[Boutique] measurement internship report summary

Part 1: Summary of Measurement Internship Report

On June 20th, 2019, we officially started a one-week "engineering survey internship". Before that, we undertook a series of preparatory work under the guidance of the teacher. First of all, it explains the practical significance and importance of measurement tasks and measurements. We followed the teacher to the location of the survey area and read the seven control points of the school in turn. In the teacher's explanation, we know that the survey area is our school district. Although the survey area is relatively large, it is basically our entire school, and the mapping is also a plan of our entire school. In this summer season, the weather is very hot, but we are still measuring the heart of An An, taking time internships, in order to complete the task as soon as possible, we are working hard every day, although very tired, very hard, but we still overcome All kinds of difficulties, and we also felt full in the internship.

Before that, we went to the construction site to conduct on-the-spot investigations under the guidance of the teacher. But after all, it is theoretical. The actual operation is still vague for us. Therefore, this internship is a big test of our undergraduate purpose since the whole semester. We regard this internship as a tempering of our future work, linking the knowledge we have learned with reality, discovering our own shortcomings in practice and making up for our shortcomings.

Measurement is a pragmatic and realistic job, and it can't be done at all. It is also important that we maintain the originality of the data in the measurement internship. In order to ensure the correctness and validity of the calculation, we have to check whether the data of each measurement point is correct. We inevitably make some mistakes in the measurement, such as the reading is not accurate enough, the bubble is not centered, etc., will cause some errors. Therefore, we perform simultaneous calculations and measurements in the measurement, so that errors can be found in time, corrected in time, and many unnecessary troubles are avoided, saving time and improving work efficiency.

Measurement is also an accurate job, and through the study of learning and internships, a basic measurement profile is formed in my mind. The content of surveying mainly includes two parts: measurement and measurement. The tasks to be completed are precisely controlled on the giant view. From the microscopic point of view, the task of surveying is to map various scale topographic maps according to requirements; to provide positioning for the brother field. Oriented services, the establishment of engineering control networks, the installation of auxiliary equipment, the task of detecting building deformation and the completion of engineering services. This task is achieved by measuring the three basic elements of all measurements: angle measurement, distance measurement, elevation measurement.

In this internship, we learned the practical ability of measurement, and also had the patience to face difficulties, and also recognized the importance of group unity and the steps of measurement. First of all, I am familiar with the use of level and optical theodolites, I have mastered the use of levelers, and mastered the methods of inspection and calibration of instruments. Secondly, in the process of checking and correcting data, I have understood the sources of various measurement errors. There are three main aspects: instrument error, external influence error, and observation error. To understand how to avoid measurement error, the maximum is to reduce the occurrence of error, that is, to do: 1, in the instrument selection to choose the appropriate instrument with higher precision. 2. Improve your own measurement level and reduce errors. 3. Reduce the error by various mathematical methods of processing data such as taking multiple measurements and taking averages. In addition, you should master a set of scientific measurement methods, in the measurement must follow certain measurement principles, such as "from the overall with a partial", "first control after the step", "from high to low" work principles, And do the check in step by step. This not only prevents the accumulation of errors, but also finds errors in time, and can improve the efficiency of measurement. Through engineering practice, I learned the things that can't be done in the classroom, such as the drawing of digital topographic maps and the measurement of broken steps, which greatly improved the ability of hands-on and brain-moving, and also expanded the ability of communication with classmates. Once a measurement internship is completed, it is not enough to rely solely on the strength and concept of a person. Only the cooperation and solidarity of the group can make the internship complete quickly and efficiently.

For more than a week, we have been adhering to our own "positions", observing, recording, calculating, and drawing... We work together to achieve better tasks. In the measurement process, we encountered many problems and problems:

When setting up the ruler, the ruler must be selected in an important place. Therefore, the selection of points is very important. At the same time, the more Philippine points are, the better. On the contrary, the excessive useless points will not only increase the time waste of measurement, calculation and drawing, but also cause large errors due to many points.

In the process of measuring with the water level meter and the total station, the center of the bubble will also produce errors, the alignment of the crosshairs, etc.

Calculate the problem. The calculation must be done by two people, a preliminary calculation, and a check. In the process, we also encountered similar problems, but we constantly calculated the correct data in the repeated test, and minimized the occurrence of errors.

We learned a lot of things during this internship. Let me better master the basic functions of measurement and some elements of measurement, and also promote the interaction with classmates, so that I understand the importance of solidarity and mutual assistance and the correct method of instrument use.

Part 2: Summary of Measurement Internship Report

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.

Through practical measurement internships, I learned a lot of real things, such as the more proficient operation of experimental instruments, and learned the things that can't be done in the classroom, such as the drawing of topographic maps and the measurement of broken parts. Improve the ability to do hands and brains, but also expand the ability to communicate and cooperate with classmates. Once a measurement internship is completed, it is not enough to rely solely on the strength and concept of a person. Only the cooperation and solidarity of the group can make the internship complete quickly and efficiently. From this ten-day measurement, it is more important to understand the important life of several things: First, the cooperation between people is very important. If they cooperate with each other, they will collapse like a sand. Especially in conjunction with such an important measurement science; Second, the unforgettable three-week measurement internship is finally over. I have learned a lot and learned a lot.

I basically mastered the knowledge of measurement in the classroom, know how to correctly use the level, total station to measure distance, angle, height difference, etc., and learned how to draw the construction and topographic map. Metrology is the science of studying the shape and size of the Earth and determining the location of the Earth. 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.

I know that everything must be done carefully and carefully. There must be no sloppy sloppyness, especially when using precision 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.

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.

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.

I cherish the school to arrange measurement internships for us, and I have a deeper understanding of the hard work of measuring work and the close relationship between the physical objects and the drawings. There is really no blueprint for nothing. In short, although I feel tired, I still want to thank the school for the internship arranged to promote students' practical ability. I will always cherish this experience, and this internship life is also memorable in my life.
