Measuring internship diary

Xxxx year xx month xx day Wednesday sunny

Get up at 6:30 today.

The data of the measured elevation has been counted last night. Today, the azimuth measurement is prepared. In the morning, I will prepare for the measurement. I studied it carefully, and I also asked a few students. What I need to prepare is the Theodolite Measurement Record Book. According to the arrangement, a total of two measurements are to be measured at one point. One measurement is divided into the first half and the second half. The upper and lower half are averaged respectively, and the average of the two averages is taken as the point. Azimuth, the measurement order is first and then right. When the face is left, first point to the next point of the test site and adjust the view to 0 degree. Then start measuring the point. After the reading, rotate clockwise to the upper point of the test station to measure. Right: The upper point of the measurement station is measured, and then the counterclockwise rotation is performed to the next point of the measurement station after the reading is completed; the second measurement method is the same as the first measurement, except that the visual number is adjusted to near 90 degrees.

In the morning, because there was no theodolite, after re-testing the third set of elevations yesterday, I went back to the dormitory early and waited for the theodolites of the first group of students.

In the afternoon, because Yue Changqing, Wu Jia, Zhang Xianfu, and Wu Jinfeng were going to take the physical examination, they had been waiting until around 3:00 pm.

This is going to start from the n18 point, but there are too many people on the playground, starting from the bc1 point. This is the first set of data we measured, and it is also a point that took the most time and energy, because everyone is not on the instrument. Too familiar, coupled with the students who played basketball to us to bring a lot of interference, the first test back to retest several times before they barely completed the task, time spent more, but the effect is not ideal They gave the singularity of the ruler to their urgency. Everyone agreed on the rotation measurement and the ruler, and I kept recording the data.

The point on the step of the first canteen is the most unpredictable, because that point is on the steps, it is not so good to set up the instrument, so it is better to toss the instrument, but the most difficult thing is not here, but the connection The point that came down, because that point could not be observed at all, only the lead line was used to lead out the point, and the light was not good at that time. Later, the line was painted, and the light of the mobile phone was used as the light source. task.

[A little thought] This is a more delicate job. The work can't be sloppy. Any mistake in the data can lead to unpredictable consequences. Therefore, it is better to spend more time on the measurement and no error. Even the data that was fabricated to complete the task.
