A wireless monitoring and early warning system for highway dangerous rocks

Abstract

The invention discloses a highway dangerous rock wireless monitoring and early-warning system, which comprises a plurality of low-power-consumption integrated wireless point type clinometers, a system main control device, a remote management center, a GPRS cloud server, a sound and light alarm system, an on-site RF wireless remote control transceiver, a lead-acid storage battery and a solar cell panel, wherein the remote management center is composed of a monitoring host and data management system and a GPRS DTU; and the sound and light alarm system is composed of a sound and light alarm warning billboard and text lamp light warning billboard. The highway dangerous rock wireless monitoring and early-warning system establishes a wireless sensing network and an on-site sound and light alarm control network based on a ZigBee wireless communication manager, forms a remote early-warning and remote control network based on GPRS, achieves on-site manual wireless control based on an RF wireless communication technology, is a system structural design based on three kinds of wireless communication technologies, provides the possibility of low power consumption of the on-site devices, and brings great convenience for on-site installation and deployment as well as manual operation of the devices.

Description

technical field [0001] The invention relates to a wireless monitoring and early warning system for road dangerous rocks, belonging to the technical field of dangerous rock monitoring. Background technique [0002] The existing dangerous rock or slope monitoring and early warning systems mostly use two-dimensional or three-dimensional image monitoring, radar monitoring, laser monitoring, ultrasonic monitoring, and fiber grating monitoring methods. The main difference is that the sensing and acquisition methods for mountain deformation are different. There are big differences. Therefore, the system configuration, device cost, construction cost and follow-up maintenance cost of each method are quite different. The background of dangerous rock monitoring on roads and railways is that high slopes are generally located in remote locations, and the slope itself is in a harsh special geographical environment. The power supply, burial, construction, and later maintenance of monitori...

AI Technical Summary

Problems solved by technology

[0005] 1) The cost of forming the device is high

[0006] Existing methods such as laser ranging, airborne radar, night vision camera, ultrasonic ranging, and fiber grating deformation measurement are applied to the monitoring of dangerous rocks and collapsed bodies. Rely on mains power or configure large-capacity batteries, resulting in higher overall system costs and higher initial investment

[0007] 2) Installation and maintenance are not convenient enough

[0008] Due to the harsh environment of the slopes on both sides of the road or railway, the installation and laying of the device is extremely inconvenient. For example, the fiber grating sensor cannot be laid on the dangerous rock of the slope to be monitored, but can only be laid along the railway under the slope; the camera, laser and The power consumption of the ultrasonic transmitter is high, and the power supply requirements are relatively high. It is necessary to lay cables or use large-capacity batteries to cooperate with solar panels for power supply. It is inconvenient to install on dangerous rock slopes.

[0009] 3) High application environment requirements

[0010] The existing camera image analysis and monitoring methods are affected by the activities of people or animals in the monitoring area, as well as the shaking and falling leaves of the vegetation in the monitoring area, which will lead to misjudgment in image processing, requiring manual analysis and intervention, and cannot achieve fully automated monitoring and early warning. ;Laser and ultrasonic monitoring methods, due to the characteristics of laser and ultrasonic, are significantly affected by the emission distance, rain, snow, fog and dust, and temperature, and have relatively high environmental requirements for the installation site

[0011] 4) The system function is not complete

[0012] Some of the existing dangerous rock monitoring and early warning systems only realize the monitoring function of dangerous rock emergencies, but do not have real-time monitoring of the gradual change process of dangerous rocks; Early warning function; some only provide early warning information to the remote center, without on-site real-time early warning facilities and functions; some have on-site early warning facilities, but the implementation settings are unreasonable, and the early warning system cannot be remotely controlled and activated, and the early warning function for vehicles and pedestrians cannot be truly realized
