A centralized controller applied to reservoir dam body monitoring system

Abstract

The invention discloses a centralized controller applied in a monitoring system of a reservoir dam body. The centralized controller comprises a manager shell, a management controller, a laser transmitter and a laser-through-hole switching mechanism, wherein a laser through hole is formed in one side surface of the manager shell; the laser transmitter is arranged at the position in the manager shell, corresponding to the laser through hole; the laser-through-hole switching mechanism is arranged on the inner side wall of the laser through hole of the manager shell; and the manager controller is respectively connected with the laser transmitter and a laser-through-hole baffle mechanism. The centralized controller disclosed by the invention has the advantages that by arrangement of the laser-through-hole switching mechanism, the automatic opening and closing of the laser through hole of the manager shell are realized; a baffle plate in the laser-through-hole switching mechanism is processed and manufactured by adopting polyethylene plates, so that the cost is lower, the effects of being durable and anti-corrosive are achieved, and no deformation is caused; and the manager controller is formed by adopting an ARM 32-bit single-chip microprocessor STM32F107 with rich and powerful functions, so that the site requirements for the whole system are met.

Description

technical field [0001] The invention relates to a reservoir dam body monitoring device, in particular to a centralized controller applied to the reservoir dam body monitoring system. Background technique [0002] After concrete dams and masonry dams are built and used for water storage, under the action of water, sediment, waves, uplift pressure, temperature, and earthquakes, deformations will inevitably occur, which will seriously lead to subsidence. There are too many cases to enumerate. Dam safety monitoring technology is an international concern. [0003] The dam structural safety monitoring system involves multiple disciplines such as optics, sensors, and electronics, and its development has gone through two stages: [0004] 1. Observation stage (1891-1964), also known as prototype observation. Because the level of monitoring at this stage is relatively low, only manual observation and testing are performed on the monitoring instruments placed on the dam structure to ...

[0008] 2. Install or bury some displacement monitoring instruments on the surface of the dam body, usually only can measure single item displacement data (horizontal displacement or vertical displacement) of the measuring point

[0012] However, in the above two invention patents, the laser through-hole baffle of the centralized controller is moved and fixed through the horizontal control mechanism of the laser through-hole baffle and the vertical control mechanism of the laser through-hole baffle. When the baffle is impacted by the outside ( Object impact or strong wind), the baffle is easily damaged, resulting in water or dust in the centralized controller box, affecting the operation of the centralized controller and making it impossible to accurately monitor the reservoir dam
