Embodiment 1

[0037] refer to Figure 1 to Figure 10 , Figure 13 , a dam safety intelligent all-round monitoring device, including an all-round tilt sensor array, all-round vision sensor, embedded system, LED lighting source, sound alarm unit, power supply unit and solar charging unit; the dam safety intelligent all-round The monitoring principle is: arrange the omni-directional tilt sensor array from the dam foundation to the abutment in the depth of the dam, and arrange each dam section in the width of the dam to form a three-dimensional internal deformation monitoring sensor network. On the one hand, the omni-directional tilt sensor array is vertically buried, and then according to the length of the dam, a group of omni-directional tilt sensor arrays are properly placed on each dam section, thus forming a tilt monitoring network in the lateral direction of the dam; when the large If inelastic deformation occurs in a certain area of ​​the dam, several omni-directional tilt sensors in th...

Embodiment 2

[0051] refer to Figure 1 to Figure 12 , the rest are the same as in Embodiment 1, the difference is that a single omni-directional tilt sensor is adopted in the dam safety intelligent all-round monitoring device, so that the dam safety intelligent all-round monitoring device only needs to be fixed on the abutment of the dam, as attached Figure 11 , 12 As shown, this implementation scheme does not need to drill holes on the dam to embed an omni-directional tilt sensor array, and has the advantages of simple implementation, convenient maintenance, and low investment cost; Insufficient horizontal displacement and so on.

Abstract

The invention relates to a safe and intelligent omnibearing monitoring device for a dam, comprising an omnibearing inclination sensor array, an omnibearing vision sensor, an embedded system, an LED lighting source, a sound alarm unit, a power supply unit and a solar charging unit. Various deformations of the dam are monitored in real time through the omnibearing inclination sensor array; and whenthe deformation of the dam exceeds a certain strain threshold, the omnibearing inclination sensor array sends a trigger signal, automatically synthesizes the information of the deformed geographical position of the dam to a local panoramic image and sends to monitoring personnel. The safe and intelligent omnibearing monitoring device for the dam has the advantages of omnibearing perception detection method, omnibearing vision confirmation area, omnibearing information issue means, easy maintenance and regulation, high real-time performance, safety and reliability, low power consumption and event trigger.

Description

technical field [0001] The invention relates to a dam safety intelligent monitoring device, which belongs to the application of embedded technology, wireless network communication technology, tilt monitoring technology and panoramic video image acquisition technology in dam safety automatic intelligent monitoring, and is mainly suitable for dam safety monitoring. Background technique [0002] The dam safety monitoring instrument is the eyes and ears for people to understand the operating status of the dam. It must be able to monitor the small physical quantity changes of the dam stably and reliably for a long time in harsh environments. Therefore, in some aspects (such as measurement accuracy and long-term stability) ) Compared with other industrial monitoring industries, its requirements are higher and more difficult. From externally observed static levels, positive and negative hammers, and laser alignment to internally observed piezometers, subsidence meters, inclinometer...
