[0022] The positioning signal device 13 can be a micro radar or Bluetooth.

[0023] The retractable tripod 15 is equipped with a servo motor, a variable rod, a power supply and a wireless transmission module, and the height of the retractable tripod 15 can be controlled by the control system 5 .

[0024] The monitoring camera 11 is a high-definition camera with the functions of remote-controlled 360° rotation and automatic fill light. The support rod 12 is a rod-type structure made of steel. The monitoring camera 11 and the support rod 12 are fixed with bolts.

[0025] When the present invention is in use, the working principle of the system is to measure the horizontality of the horizontal rotating disk 4 through the inclinometer 6, and then the control system 5 uses the extension and contraction of the servo electric cylinder 3 to complete the leveling work of the device. The servo electric cylinder 3 adopts a miniature specification, and then cooperates with the positioning signal device 13 of the ruler rod system to search and locate the ruler rod system. With the help of the rotation of the horizontal rotating disk 4, the lens of the wide-angle camera 8 is aimed at the scale surface of the indium steel ruler 14. The focus servo motor 9 and the electronic eyepiece 10 are used to adjust the clarity of the surface code of the indium steel ruler 14 captured by the wide-angle camera 8, so as to achieve the best measurement effect and perform measurement readings, thereby realizing intelligent remote control of settlement observation.

[0026] The specific installation process is as follows: first, the control system 5, wide-angle camera 8, focusing servo motor 9, inclinometer 6, electronic eyepiece 10, micro servo electric cylinder 3, horizontal rotating disk 4, housing 7 and support 2 form the main measuring device, the support 2 is installed on the fixed base 1, and the base 1 is fixed at the measuring station position; secondly, the monitoring camera 11 is installed on the support rod 12 to complete the assembly of the monitoring system; finally, the positioning signal device 13, indium steel ruler 14, retractable tripod 15 and level bubble 16 form a ruler rod system, and the ruler rod system is installed at the measuring point and reference point positions. At this time, the installation of the entire settlement observation system has been completed.

[0027] This system adopts the design of inclinometer 6 and micro servo electric cylinder 3 to realize automatic leveling of the device and improve the efficiency of leveling. By setting the horizontal rotating disk 4, the problem of horizontal rotation of the device is solved.

[0028] The working process of the above unattended remote-operated displacement observation system is as follows: According to the predetermined plan, the system is installed at a predetermined position, and the information measured by the inclinometer 6 is used to adjust the micro servo electric cylinder 3 in cooperation with the remote control software and the control system 5, so that the horizontal rotating disk 4 is in a horizontal state, and the working state of the device is checked in real time with the help of the monitoring camera 11; then, according to the coordinate information of the ruler system located by the positioning signal device 13, the control system 5 is used to control the horizontal rotating disk 4 so that it rotates horizontally according to the predetermined target position until it reaches the predetermined position. When the device rotates horizontally, the rotation position can be checked in real time with the help of the monitoring camera 11.
