Description

technical field [0001] The invention relates to an automatic monitoring system used in engineering, and is especially suitable for a fully automatic deformation monitoring system for large engineering bodies based on laser alignment. Background technique [0002] The current safety assessment of dams, reservoirs, bridges and other engineering bodies mainly depends on deformation monitoring data, such as horizontal displacement, vertical displacement, deflection, inclination, surface joints and cracks, etc. The monitoring methods of horizontal displacement mainly include: movable target method, small angle method, positive and negative vertical line, tension line, vacuum laser alignment method, front intersection method and wire method, etc. The monitoring methods of vertical displacement mainly include: precision level, static level, triangular elevation, connected tube vacuum laser alignment method, etc. These methods were initially measured manually by optical instruments...

Problems solved by technology

[0003] Vacuum laser alignment system requires cooling equipment and maintains a certain degree of vacuum. It is difficult to construct and install, and it is difficult to guarantee the reset accuracy, sensitivity and vacuum degree of the wave zone plate for a long time. It affects the measurement of other measuring points. It is difficult to coordinate the cooling water and vacuum pump for a long time. If there is air leakage in the system or the reset failure of the wave zone plate, the maintenance project will be large.

The investment cost of the GPS automation system is relatively high. The total cost of the Geheyan system exceeds 6 million yuan. Excluding the software, since each deformation measurement point needs to be equipped with an antenna and a GPS receiver, the cost of a single point is also more than 200,000 yuan, and its measurement accuracy is affected. The location and measurement time have a great influence. For example, observations cannot be carried out in the corridor. To obtain accurate measurement values ​​of the measurement points, the measurement time will be longer. More importantly, the GPS satellites are launched by the US government for military purposes. From a strategic perspective Generally speaking, the monitoring of reservoirs, dams, and bridges in a country cannot rely on this method
