Measuring the internship experience

Part 1: Measurement Internship Experience

The two-week internship was over. From the beginning of the joy to the discouragement of the period, to the end of the end, I gained a lot and learned a lot.
The theoretical knowledge of engineering geological survey has been fully utilized in this internship, and the theoretical knowledge that is difficult to understand in the classroom has been basically mastered through its own hands-on operation. There is also a preliminary understanding and understanding of the use of level, theodolite and total station. These instruments can be used to perform some basic engineering geological measurement tasks. And for two weeks, I was completely familiar with these instruments from the beginning to the present, and all of them benefited from the teacher's careful teaching. The help of the students. Make yourself a big improvement.
After two weeks of internships, I personally experienced the hardships of being a civil servant. Although it was only a few days, we got up at 5:30 in the morning and did not rest at noon. Although the sun is in the head, everyone has no complaints. All of them worked with the team leader so that the work of our group could be carried out smoothly. In the past two weeks, our six people have further deepened their understanding of each other. It is not necessary to say the feelings between us. It is good to say in the Northeast.
This internship made me realize that as a team, everyone should make their own efforts, even if you can't contribute in the main link, it doesn't matter. There is a saying, it can be more work, yes. As a team, our goal is to make our missions perfect. But I think everyone in the team should go to study, should be given to practice, the task is completed, the classmate who always works will become more and more skilled, while others will fall into a big cut during this period. I don’t think that whenever I want to reach out, I don’t wait for someone to take something for you. Is there a saying that opportunities always give people who are prepared again? We should let ourselves develop in a normal way. Use all the resources you can use to discover your potential and arm yourself with knowledge. Only then can you become a strong person.
The end of the internship is just the end of a period. What I have learned will play a positive role in my future study and work life. Learning is a matter of no end. Only by persisting and unremitting efforts, you will harvest the East you want.
Finally, I ended my internship report with my motto:
Instead of letting the society torment yourself, it is better to let yourself torture yourself.

Chapter 2:

The intense and unforgettable week of measurement internship life ended in a cheering victory. Through this internship, we have consolidated, expanded and deepened the theoretical knowledge we have learned from the classroom, mastered the basic operation of the DJ-6 theodolite, and achieved a certain level of proficiency, and also had the opportunity to learn how to draw the topographic map. . While practicing the ability to draw sketches and use CAD drawings, you also accumulate your own drawing experience and improve your drawing speed. Not only obtained the preliminary experience and basic skills of measuring actual work from this professional internship, but also focused on cultivating our independent work ability, cultivating our ability to find problems and solve problems at the test site, and further proficient in the use of measuring instruments. Skills, improve data computing ability and sensitivity to data, and have a comprehensive and systematic understanding of the whole process of mapping large-scale topographic maps in small areas. This knowledge is often rarely touched and noticed by me at school, but It is also a very important and very basic knowledge, and a certain solid foundation can be used to determine the superstructure. Therefore, this internship not only allowed me to accumulate a lot of experience, but also taught me a lot of practical knowledge, because we all understand that practice is the only criterion for testing truth, the Marxist dialectical materialist truth!
This internship also made me realize that the surveying and mapping profession is a team's job! There are seven team members in our group. Each person's work tasks are different from their respective strengths. We can work together to achieve higher efficiency. My main task is to use the instrument to measure the data. At the same time, this internship also expanded our ability to communicate and cooperate with teachers and classmates. Because people used to say that the surveying and mapping profession especially needs teamwork spirit, I have not fully understood. Indeed, once a measurement internship is completed, it is not enough to rely solely on the strength and concept of one person, and it is impossible to do the work to be done. Only the cooperation and solidarity of all the members of the group can make the internship complete quickly and efficiently. The so-called "three stinkers, the top of Zhuge Liang." In addition, this measurement internship cultivated the ability of our team to work together, enhanced the feelings between the students, and deepened the friendship. During the internship process, it is inevitable that we will encounter some embarrassing things, making everyone unhappy, but we can communicate and communicate in a timely manner, forget the unpleasantness of yesterday, and welcome the new sunrise! The principle of completing this internship is to let each team member learn the knowledge and actually operate, and can complete a job separately, and then rotate after the corresponding exercise effect, in order to achieve the purpose of joint development, rather than simply grab the time. , rushing to the progress, and getting things done, this will not meet the expected goals of the internship. Even if the work is over, 100% must be re-appeared. This is too much to waste. It is a waste of time and energy. It has destroyed the enthusiasm of the team members. Because the surveying and mapping profession has its own "Surveying and Mapping Law", it stipulates the accuracy requirements of the surveying map, which must be observed by every surveying and mapping personnel. In addition, if we are so arrogant in our daily life, we are not responsible for ourselves. Now we are used to it, and we will return to work in the future! In addition, we have the opportunity to exercise so little, and the horse is almost a waste of a great opportunity. It is a pity to lose it! Therefore, each member of our group has independent observations, record each station, and the theodolite measurement is performed on the spot, and the problem is solved in time. There is no check on the previous step, and the next step is never carried out. Measurement, to check in step by step, after returning, it is necessary to accurately calculate the internal business, because doing so can not only prevent the accumulation of errors, but also find errors in time, and can improve the efficiency of measurement and avoid inaccurate measurement. Retest. Even if we retest, we will rework with the rigorous attitude and will not be sloppy. Until the measurement requirements are met. We know that what we need to do in engineering is to be careful, patient, persevering and rigorous. Only in this way will it be easy to get on the job in the future and take less detours.
For example: pay attention to the following points when making maps:
The ruler should be straight and try to avoid shaking. When there is shaking, you should select the data to read when it is the smallest. Be sure to level the bubbles in the field of view before reading, otherwise the error will be large.
When measuring the angle with the theodolite, if the target is small, it is best to make the single line coincide with the target. If the target has a certain width, the target can be clamped with the double wire.
Be careful when measuring, because if you touch the instrument a little, you need to re-adjust the centering level, otherwise it will cause data errors and may cause damage to the instrument.
When reading data, each member must be careful, both accurate and decisive, and cannot hesitate. Any mistake can lead to the retirement of the final result.
The selection point is very important. The point must be selected in a representative place. At the same time, it should be noted that not the more points, the better. On the contrary, the excessive useless points will not only increase the labor and time required for measurement, calculation and drawing, but also Because of the many points, the clutter produces a large error.
It is necessary to first determine the roads and main buildings, and then add the remaining minors. This is not only clear, but also conducive to the accuracy of the drawings and the comparison of physical objects and graphics at any time to verify the accuracy of the measured data. We also need to be able to do a good job of measuring the range, avoid missing and retesting.
Unity is strength, discipline is the guarantee of unity through each team member, when we have completed the work of mapping, and everyone is excited when we see the drawings we draw. In the experience of our group of students in the exchange measurement, everyone feels that there are many gains. Some say that the exhibition point of the instrument is very important, because it is related to the size of the error, and some say that the midpoint of the measurement cannot be set too far, and some It is necessary to minimize the error when measuring the instrument height and target height of the total station, the use of the ruler pad during the leveling of the level gauge, and the accurate centering and leveling of the bubbles during the process of the instrument, and we must have a protective instrument. The heart should be carefully cared for by the instruments used. In school, it is even more important to go to work, so that you can avoid unnecessary troubles and so on. I think everyone gets up at 6 o'clock every morning and puts the instrument on the back of the instrument to measure with the big sun. Everyone who has calculated the error is discussing and modifying together. If necessary, they will take the trouble to re-measure. With the strength of unity, we still do very much. Strong. I also learned from others that things that were not too clear before, such as the processing of data, the simplified observation of broken points, and some of the questions of drawing were answered in the measurement.
Seeking truth and pragmatic measurement internships, I have learned a lot of real things, have a comprehensive opportunity to apply the measurement knowledge of the previous piecemeal, control measurement and topographic mapping process has a good understanding, learned The drawing of topographic maps and other things that can't be done in the classroom and the more skilled use of theodolite measuring instruments and tools have consolidate the theoretical teaching knowledge, improve the practical operation ability, and expand the communication cooperation with the students. ability. Of course, there are many teachers and teachers who help. When each of our groups basically draws a good picture, the teacher checks the results of each group. If there is a problem, let us correct it in time. In fact, think about the measurements on the campus every day, we are also a good scenery. I still remember that at 7 o'clock in the evening, we had to re-measure because of a site error. We were busy for a long time and we didn't even have time to eat dinner. In short, we also experienced a lot of ups and downs during the week. Some measurements were smooth and even zero error. Sometimes the measurement hit the wall, but everyone insisted. When we finished the measurement, everyone was very happy. Although everyone did not want to test when they were lazy, it was quite good. At the end of the internship, everyone faced the dark face and skin in the mirror. Everyone No complaints, because everyone understands the hardships. In addition, surveying and mapping is a hard-working profession. If you don't sweat or don't suffer, you can't make achievements! This week's internship also gave us a lot of lessons: because of the misreading, mistaking, and miscalculation of a certain data, it has brought us a lot of trouble, so that we know that we must do anything seriously and have a A rigorous attitude, as the saying goes, "attitude determines everything." The unity of a group is also crucial, and it is related to the progress of the entire group. Previously, our team did not have a tacit understanding, and the division of labor was not reasonable enough. The overall progress was greatly affected. Later, through the exchanges within the group, the above problems were completely solved. The progress of the internship has been greatly improved, and the progress and effect are naturally brought up.
Failure is the mother of success! I cherish the important link between the theory and the reality of the school's arrangement of internships for us. I have a deeper understanding of the close relationship between the physical objects and the drawings. I understand the drawings, what kind of objects should be displayed, and some of them are in the drawings. The place that I can't understand is so simple and clear in front of the real thing. In short, I would like to thank the school for the internship arranged to promote students' practical ability. I will cherish this experience forever. At the same time, this internship life is also the most memorable in my life.

Chapter three:

First of all, I basically mastered the knowledge of measurement in the classroom, knowing how to correctly use the level, theodolite, total station to measure distance, angle, height difference, etc., and learned how to draw the construction and topographic map. Since it is to be measured, it is inseparable from practice. Practice is the best test of the knowledge of surveying. I only have a lot of specific knowledge in the classroom, especially the use of the instrument is a mess. When the first day began to measure, my heart was still bursting with a burst of enthusiasm: how to carry on the task. When you start, it is not difficult to find out. Listen to others or read the textbook, and then do it yourself. In order to improve efficiency and measurement accuracy, you should practice frequently so that you can do the opposite.
Secondly, I understand that everything must be done carefully and carefully. There must be no sloppy sloppyness, especially when using sophisticated instruments such as level gauges and theodolites. Because a slight error can lead to a large deviation of the data, it will lead to other measurement errors in the future, and eventually lead to errors in data calculation. For example, when we first start measuring the angle, a reference point is not aimed, resulting in a small angle. Then the angle closure difference does not meet the requirements. After verification, it is found where the problem lies.
I also learned to work hard and learn the style of hard work. During the internship period, it is just the winter season. The temperature in Linyi is very low. We are a big challenge for the open-air operation. We have changed the habit of sleeping lately. We will get up at 7:00 in the morning and start measuring at less than 8:00. The winter days are dark early, so we must make full use of the daytime until it is too dark to see at night. Once a measurement internship is completed, it is not enough to rely solely on one's strength and thinking. Only the cooperation and solidarity of the group can make the internship complete quickly and efficiently. Each of our team members learned the knowledge and actually operated it, instead of grabbing the time, rushing to the progress, and rushing to work. We know that what we need to do in engineering is to be careful and rigorous.
Through this internship, I also summed up some things that should be paid attention to when measuring. The ruler should be straight and try to avoid shaking. When there is shaking, you should select the data to read when it is the smallest. Be sure to level the level bubble of the level field before reading, otherwise the error will be large. When measuring the angle with the theodolite, if the target is small, it is best to make the single line coincide with the target. If the target has a certain width, the target can be clamped with the double wire. Be careful when measuring, because if you touch the instrument a little, you need to re-adjust the centering level, otherwise it will cause data errors and may cause damage to the instrument. When reading data, each member must be careful, both accurate and decisive, and cannot hesitate. Any mistake can lead to the retirement of the final result.

Chapter 4:

Measurement is first and foremost a precise work. Through the study of measurement in the classroom during school, I have formed a basic, theoretical measurement profile in my mind. The purpose of the internship is to apply these theories. Linked to actual engineering. Metrology is the science of studying the shape and size of the earth and the location of the ground. In essence, the main task of metrology is to determine the position of the ground target in three dimensions and the change with time. In the information society, the role of metrology is increasingly important. Measurement results, as the basis of the Earth's information system, provide the most basic spatial location information. The construction of information highways, basic geographic information systems, and various thematic and professional geographic information systems are all urgently required to establish a measurement database and measurement results information system with uniform standards and sharing. Therefore, measurement is the most reliable and accurate means of acquiring and updating basic geographic information. There are many types of surveying, such as general surveying, geodesy, photogrammetry, and engineering surveying. As a student of the Department of Architectural Engineering, we have to learn all aspects of measurement. The foundation of surveying and mapping is the basis of these expertise.
Through this training, I learned that it is not enough to rely on the strength and concept of a person to complete a measurement internship. It is impossible to do the work to be done. Only the cooperation and solidarity of all the members of the group can make the internship complete quickly and efficiently. The so-called "three smugglers, the top of Zhuge Liang", only if we unite, what difficulties are no longer difficult. In addition, this measurement internship also cultivated the ability of our team to work together, enhanced the feelings between the students, deepened the friendship, and connected some of the original "strangers" closer. Of course, in the internship process, it will inevitably encounter some embarrassing things, making everyone unhappy, each has its own methods and insights, but we can communicate and communicate in a timely manner, the wrong party is not so stubborn, the right party Not so obvious, I forgot the unpleasantness of yesterday, and greeted the new sunrise! Of course, I believe that the other purpose of the school to let us train is to let each of our students have a deeper understanding of how to use the total station and level. And it is possible to complete a job alone, and then rotate after the corresponding exercise effect to achieve the purpose of joint development, instead of simply grabbing the time, rushing to the progress, and rushing to work, at this point our group is doing very well. Seriously, each team member conducts independent observations and records each station. The total station measurement is performed on the spot, and the problem is solved in time. There is no check on the previous step, and the next measurement is never taken. To check the steps step by step, and to calculate the internal industry accurately after returning, because this will not only prevent the accumulation of errors, Finding errors in time can improve the efficiency of measurement and avoid inaccurate measurement and retest. Even if we retest, we will rework with the rigorous attitude and will not be sloppy. We know that what we need to do in engineering is to be careful, patient, persevering and rigorous. So we have been overcoming the shortcomings of the past, step by step and want to move forward!
From this internship, I summed up a few points to avoid large errors, such as:
The ruler should be straight, try to avoid shaking. When there is shaking, you should select the minimum data, and then adjust the bubble of the field of view before entering, otherwise the error will be very large.
When reading data, each member must be careful, both accurate and decisive, and cannot hesitate. Any mistake can lead to the retirement of the final result.
The selection point is very important. The point must be selected in a representative place. At the same time, it should be noted that not the more points, the better. On the contrary, the excessive useless points will not only increase the labor and time required for measurement, calculation and drawing, but also Because of the many points, the clutter produces a large error.
Unity is strength, discipline is to ensure the unity of work through each team member. When we learn from the experience of our group of students in exchange measurement, everyone feels that there are many gains. Some say that the exhibition point of the instrument is very important, because it is related to the error. Size, some say that the measurement midpoint can not be set too far, the level measurement process must be used and the precise alignment and leveling of the bubbles during the instrument process, and we must have a heart care instrument, the instrument used Be careful, in school, and even more so when you are on the job, so you can avoid unnecessary troubles and so on.

Chapter 5:

On June 1st, 2019, at 8:00 am, Mr. He gave us an engineering surveying internship mobilization meeting. Our engineering management students were led by Mr. He to the school's No. 13 teaching building for a two-week engineering survey internship. Our class has 32 people and is divided into 6 groups. Zhao Jian, Zhang Yao, Deng Qiang, Xiong Zicai and I are the first group.
Now, the two-week internship is over. Through this internship, I have a deep understanding of the importance of linking theory with practice. Because it was in the summer, and these days just caught up with the hot weather, the hot sun took the lead, but during the internship, the students showed a high level of work enthusiasm and collaboration. Not afraid of the heat, even sleepless nights. Data is measured during the day, and the points are stepped up at night. Work closely together and learn from each other. The surveying and mapping work was carried out very seriously, and the internship task was completed well.
Through the measurement of internships, there are also some experiences. First of all, measurement is an accurate work. Through the process of studying engineering and measuring this course, I have formed a basic and theoretical measurement profile in my mind. The purpose of the internship is to apply these theories. Linked to actual engineering. Metrology is the science of studying the shape and size of the earth and the location of the ground. In essence, the main task of metrology is to determine the position of the ground target in three dimensions and the change with time. In the information society, the role of metrology is increasingly important, and measurement results serve as the basis of the Earth's information system, providing the most basic spatial location information. The construction of information highways, basic geographic information systems, and various thematic and professional geographic information systems are all urgently required to establish a measurement database and measurement results information system with uniform standards and sharing. Therefore, measurement is the most reliable and accurate means of acquiring and updating basic geographic information. There are many types of surveying, such as general surveying, geodesy, photogrammetry, and engineering surveying. As a student of the Department of Architectural Engineering, we have to learn all aspects of measurement. The foundation of surveying and mapping is the basis of these expertise.
Through this study, I learned the practical ability of measurement and the endurance to face difficulties. In order to complete the task as quickly as possible, we are working hard every day, although it is very tired and very hard, but we have overcome all kinds of problems. Difficulties, we also felt enriched in the internship, and also learned the unity and tacit understanding between the groups, and exercised a lot of their ability to survey and draw. First of all, I am familiar with the use of level and theodolite, and have mastered various methods of using the level and theodolite, and mastered the inspection and calibration methods of the instrument. Secondly, in the process of checking and correcting the data, the sources of various measurement errors are understood. There are three main aspects: instrument error, observation error, and external influence error. This better understands how to avoid measurement error and minimize the measurement error, that is, to select the appropriate instrument with higher precision in instrument selection. The error is eliminated by mechanical rotation or the like on the premise that the accuracy of the instrument is limited. Improve your own engineering measurement level, master the correct method, and standardize the operation. Reduce the level of error. Through various mathematical methods of processing data such as: temperature correction in distance measurement, correction of ruler length, averaging multiple measurements, correction of values, etc. to reduce errors. Third, in addition to being familiar with the use of the instrument and understanding the source and reduction measures of the principle mastery error, you should also master a set of scientific measurement methods, and follow certain measurement principles in the measurement, such as: "from the whole to the local" The principle of “controlling the broken parts first” and “from high-level to low-level” and doing “checking step by step”. This not only prevents the accumulation of errors, but also finds errors in time, and improves the efficiency and accuracy of the measurement. Through practice, I really learned a lot of real things, such as the operation of the measuring instrument, leveling, more familiar with the center, learned the digital topographic map drawing and the measurement of the broken parts, etc. Something, but during the internship, I did it. Although it was not perfect, I was successful in the twists and turns. It greatly improves the ability to do hands and brains and handle various situations.
For more than a week, we have been adhering to our own "positions", observing, recording, calculating, and delineating..... We work together to achieve better tasks. In the measurement process, we also encountered many problems, problems and difficulties. It is still very well overcome by the teacher's point of view and our serious treatment. I am very grateful for this internship, which has provided us with a chance to learn together, make progress together, and work together to complete a project. I have benefited a lot.
During the internship process, it was also found that the popularity of the internship was very important. The many years of educational activities carried out by the Chinese government to promote economic construction have achieved great success. People's concepts and consciousness have been greatly improved. However, there are still some shortcomings in the depth and breadth of economic development. Our activities can't just be superficial, we need to go deep into reality, and really let people understand the meaning. On this basis, we will gradually establish people's belief in economic development and establish the sacred status of economic development. Only in this way can our country's economic construction have hope.
