Traditional blueprint adjustment largely limits the review work of surveyors. First, it is not conducive to portability. Second, it is not convenient for on-site modification, resulting in rework. Revise. However, the present invention can solve these problems to a large extent by utilizing the bluetooth transmission module of the data acquisition equipment (total station and RTK) to transmit the measured data to the electronic drawing board for immediate measurement, drawing and calculation. In addition, the present invention also has the following characteristics:

1) Convenience

Electronic drawing board is a kind of electronic mapping software, which uses iPad equipment, which makes it have a certain degree of portability, which greatly reduces the burden on field personnel. At the same time, it avoids printing drawings and saves a lot of paper quality data and protect the environment.

2) Timeliness

During the adjustment and drawing process, field personnel can directly modify and save errors on the electronic drawing board to avoid certain errors caused by field personnel due to problems such as handwriting and time. In addition, field personnel can also ensure the accuracy of the measured ground objects and prevent errors caused by the inability to measure accurate values due to paper documents, thereby ensuring data reliability. Quality inspectors can also directly use the electronic drawing board to record problems, thereby reducing the workload of their paper record problems and improving the efficiency and accuracy of quality inspection.

3) Operability

The electronic drawing board not only has certain advantages in data editing and format management, but also has a certain degree of calculation, which can directly calculate the coordinate information of conditional points and the position information between points, which is very powerful for field personnel Use function.
