Abstract
In order to improve the efficiency of precise trigonometric leveling by simplifying its
operation steps and process,we propose an automatic control strategy of precise
trigonometric leveling, and we discuss the system architecture design,
implementation mechanism of automatic control strategy and key function module
division in detail. Then we develop an automatic measurement control system
composed of measuring robot control application and server program. The system is
used in Chongqing rail transit project,and the result shows that the linkage control
of the observation process between the main station and the auxiliary station and
the automatic control of the instrument measurement are realized by the system.
The whole process does not need manual intervention,and the measurement error
is checked in real time,which not only ensures the accuracy of the original data
record,but also significantly improves the work efficiency.
