Description

Technical Field

[0001] The utility model relates to the technical field of geological disaster monitoring, in particular to a multifunctional geological disaster monitoring gateway receiver circuit structure. Background Art

[0002] Geological disasters refer to natural disasters caused by changes in the geological environment, including landslides, mudslides, ground collapse, earthquakes, etc. These disasters pose a serious threat to agricultural production and farmers' lives. The geological disaster monitoring system can monitor the occurrence of geological disasters in real time, issue early warnings in a timely manner, and provide a scientific basis for disaster prevention and mitigation. The geological disaster monitoring system mainly includes geological disaster monitoring equipment and geological disaster monitoring information management system. The geological disaster monitoring equipment mainly includes geological radars, seismographs, water level gauges, displacement meters, etc., which can monitor the occurrence and development of geological disasters in real time. The geological disaster monitoring information management system can process and analyze the monitoring data in real time, generate geological disaster early warning information, and provide a scientific basis for disaster prevention and mitigation decisions.

[0003] At present, the commonly used methods for landslide monitoring include geodetic method (using theodolite, level, rangefinder, etc.), satellite positioning method (using GNSS and RTK receivers), joint measurement method (using steel tape measure, vernier caliper, telescopic automatic instrument, joint meter, displacement meter, etc.), inclinometer method (using borehole inclinometer, multi-point hammer, inclinometer, etc.), settlement method (using sinker, convergence meter, static level, water pipe inclinometer, etc.), strain measurement method (using tubular strain gauge, multi-point displacement meter, sliding micrometer, etc.

[0004] Among them, GNSS receiver is also one of the commonly used equipment for landslide monitoring. However, the existing GNSS receiver has relatively single functionality. It usually defaults to static mode during use and reports data once every hour by default. There is a situation where reporting is not timely. Therefore, a multifunctional geological disaster monitoring gateway receiver circuit structure is proposed. Utility Model Content

[0005] The utility model is a multifunctional geological disaster monitoring gateway receiver circuit structure proposed to solve the shortcomings in the prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a multifunctional geological disaster monitoring gateway receiver circuit structure, including a power module, a central processing module, a display module, a data module and a high-definition camera, wherein the central processing module is electrically connected to the display module, the data module and the power module;

[0007] The data module includes a GNSS positioning module, a 3-axis acceleration sensor, a 4G communication module, a data interface module and an Ethernet interface module, and the data interface module is connected to a high-definition camera.

[0008] Furthermore, the power module is electrically connected to a lithium battery. The lithium battery has a low self-discharge rate and can maintain a high power level even when not used for a long time. At the same time, it can provide 12-24V DC power to the power module.

[0009] Furthermore, the GNSS positioning module is used to receive satellite positioning signals and output coarse positioning messages. The advantages of the GNSS positioning module mainly include high precision, small multipath effect, strong occlusion adaptability, short delay, small size, low power consumption and fast data transmission speed.

[0010] Furthermore, the 3-axis acceleration sensor is used to obtain instantaneous acceleration value and inclination data. The 3-axis acceleration sensor is a prior art, and a corresponding model can be selected according to actual needs.

[0011] Furthermore, the 4G communication module is used to provide high-speed data transmission and wireless connection. The positioning message is processed by the central processor and then forwarded to the cloud server through the 4G wireless communication module.

[0012] Furthermore, the data interface module is used to receive transmission data from a high-definition camera, and the high-definition camera is used to obtain on-site high-definition image data. The central processing unit receives the high-definition camera image data through the data interface module.

[0013] Furthermore, the Ethernet interface module is used for network data connection, and the reported data can also be transmitted through a wired network.

[0014] Beneficial effects of the utility model:

[0015] When the utility model is in use, the multifunctional geological disaster monitoring gateway receiver circuit structure, through the set power module, central processing module, display module, data module, high-definition camera, GNSS positioning module, 3-axis acceleration sensor, 4G communication module, data interface module and Ethernet interface module, is in the monitoring process as a whole. When the built-in 3-axis acceleration sensor of the receiver detects an abnormality, it will trigger the GNSS positioning module, thereby changing the data monitoring reporting frequency and starting intensive monitoring. At the same time, the high-definition camera will automatically take a photo of the scene and upload it to the server. If both the GNSS receiver and the inclinometer accelerometer detect abnormal changes, a warning signal will be issued on the web side, which requires manual processing. In addition, the use of a comprehensive analysis of multiple data can greatly reduce the number of false alarms. BRIEF DESCRIPTION OF THE DRAWINGS
