[0002] High slopes are widely present in engineering construction, such as high slopes in water conservancy and hydropower, high slopes in mines, and high slopes in irrigation areas. They are the main geological environment and engineering bearing bodies for engineering construction. High slopes are soil slopes with a height greater than 20m and less than 100m or rock slopes with a height greater than 30m and less than 100m.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] The present invention provides an irrigation channel high slope safety monitoring system, whose working principle is to monitor the high slope area and the equipment in the area through a hydrological environment monitoring component, an irrigation area engineering monitoring component, and a protection net monitoring component, to realize data accumulation based on safety monitoring, so as to achieve the purpose of realizing real-time monitoring of the high slope, timely monitoring of the stability of the high slope, real-time grasp of the deformation law, characteristics and development trend of the high slope, and improving the application safety of the high slope and providing experience for engineering design and maintenance.

[0026] The present invention is further described in detail below with reference to examples and specific implementation modes.

[0027] like Figure 1As shown, a safety monitoring system for irrigation channel high slopes includes a hydrological environment monitoring component for monitoring the area, an irrigation project monitoring component for monitoring the irrigation project in the irrigation channel high slope area, a protection net monitoring component 3 for monitoring the protection net, a video monitoring component 4 arranged in the high slope area, and a control terminal 5 that receives data monitored by the hydrological environment monitoring component, the irrigation project monitoring component, the protection net monitoring component, and the video monitoring component. The hydrological environment monitoring component, the irrigation project monitoring component, the protection net monitoring component, and the video monitoring component can send the monitored data to the control terminal by wireless communication.

[0028] The hydrological environment monitoring component includes a hydrological monitoring unit 11 for monitoring groundwater level, pore water pressure, river water level, flow, water intake, water consumption, discharge (return) volume, groundwater extraction volume, and water quality, and an environmental monitoring unit 12 for monitoring rainfall, evaporation, ground temperature, and earthquakes.

[0029] The irrigation project monitoring component includes a first project monitoring unit 21 for monitoring the start and stop information of machinery at each pump station, gate, and hydropower station in the irrigation area, and a second project monitoring unit 22 for monitoring the pressure in the pipeline and the surface. The second project monitoring unit includes a horizontal displacement monitoring unit for monitoring surface displacement, a vertical deformation monitoring unit for monitoring the development trend of surface deformation, a crack monitoring unit for monitoring surface cracks, and a retaining structure monitoring unit for monitoring the deformation and stress of the retaining structure. Through the monitoring of the above data, the data processing of the control terminal can realize the analysis and judgment of the project status, compile and analyze the slope safety monitoring data according to the monitoring requirements, generate relevant reports and graphics, and ensure the safe operation and management of the project.

[0030] The protective net monitoring component is used to monitor the performance of the SNS flexible protective net. The protective net tension monitoring system includes a tension sensor, a signal conditioner, a data collector, an RS485 converter, a tension collection software, and a power supply module; the tension sensor is used to monitor the elastic force of the SNS flexible protective net. At the same time, the data monitored by the tension sensor is amplified by the signal conditioner and enters the data collector. The data collector calibrates the collected data and sends it to the tension collection software through the RS485 converter, and the tension collection software analyzes it; the power supply module supplies power to each part. When flying rocks or falling objects occur, the force on the SNS flexible protective net changes, and the tension sensor collects the tension of the protective net. The output signal is amplified by the signal conditioner and enters the data collector. The data collector calibrates the collection parameters and communicates with the protective net tension collection software of the central station through the RS485 interface according to the MODBUS protocol via the Ethernet / RS485 converter and the optical fiber ring network. The protection net tension acquisition software packages the collected data according to the SCSW008-2011 protocol and uploads it to the telemetry data receiving and processing software, which writes the real-time data table of the protection net tension monitoring in the database, and realizes the data display, query, report, analysis and early warning functions on the 3D GIS platform. When the system finds that the situation exceeds the safety range, such as horizontal displacement, vertical displacement, etc. exceeds the monitoring allowable value, it will trigger an alarm, and the system will automatically start the mobile phone SMS alarm function, so that relevant personnel can take emergency preventive measures in time.

[0031] The video monitoring component includes cameras installed in various areas, and the cameras send video data to the control terminal synchronously. Cameras are generally installed near high slopes prone to landslides. The video monitoring component is based on the third-generation digital, networked video monitoring system, integrating the latest research results in image processing, computer vision and artificial intelligence, and using digital computing to achieve automatic analysis and automatic alarm of abnormalities and emergencies in the monitoring scene. When installing the camera, a concrete platform can be poured in a stable position around the slope monitoring section, and the video equipment can be fixed on the platform. Regular inspections should be conducted to see if the video equipment is stable. If damaged, it should be replaced and repaired in time to ensure the continuity of monitoring work.

[0032] The control terminal is a control computer capable of analyzing and processing various data.

[0033] The wireless communication method is a short-distance wireless communication method or a long-distance wireless communication method. The details are as follows:

[0034] (1) For short-range wireless communication, dedicated wireless transceiver equipment can be used to establish a wireless local area network, using microwaves as the wireless transmission medium. Depending on the actual situation, the extended spectrum method or narrowband modulation method can be selected. The former has stronger security and anti-interference capabilities and has less interference effects on other electronic devices. The latter does not need to occupy more frequency bands and can generally choose dedicated frequency bands. Currently, the commonly used NB-Lot or Zigbee technologies belong to the narrowband application type. Wireless transceiver equipment includes modems or wireless bridges.

[0035] (2) Long-distance wireless communication method, using existing communication networks such as GSM / GPRS, CDMA mobile network and wireless transceiver module, using RS232 as the external communication interface, to build a wireless remote monitoring system, so that the location of the monitoring station and the control center can be unrestricted by distance.

[0036] High slope monitoring requires the organization and feedback of monitoring results to guide construction and maintenance work. The processing and analysis of slope observation data is an important part of the slope monitoring data management system, which is used to forecast and warn the future condition of the slope, and to scientifically evaluate the stability of the slope, predict possible slope damage, and ensure project safety.

[0037] Through the above method, the irrigation channel high slope safety monitoring system provided by the present invention monitors the high slope area and the equipment in the area through the hydrological environment monitoring component, the irrigation area engineering monitoring component, and the protection net monitoring component, realizes data accumulation based on safety monitoring, and achieves the purpose of realizing real-time monitoring of the high slope, timely monitoring of the stability of the high slope, real-time grasp of the deformation law, characteristics and development trend of the high slope, and improving the application safety of the high slope and providing experience for engineering design and maintenance.

[0038] The above is only a preferred implementation of the irrigation channel high slope safety monitoring system disclosed in the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
