Embodiment 1

[0059] like Figure 1-3 , a kind of debris flow monitoring and early warning sensor device based on wireless ad hoc network, including MCU, battery, three-axis acceleration sensor, geoacoustic sensor, vibration sensor, battery voltage detection circuit and power management circuit, MESH network module; described acceleration sensor , geoacoustic sensor, vibration sensor, and battery voltage detection circuit are all connected to the input interface of the MCU through the A / D converter (including the ADC that comes with the MCU), and the MESH network controller is connected to the MCU. [It can monitor the acceleration and inclination of the sensor caused by the movement and deformation of the soil. It can also monitor the vibration caused by the movement of sand and soil around the sensor at the same time, and it can also monitor the low-frequency ground sound generated by the debris flow at the same time. 】【MCU is a micro-power microcontroller】

Abstract

The invention discloses a wireless self-networking group detection based mudslide early warning sensing device, system and method. The system comprises an RTU (remote terminal unit) and multiple mudslide monitoring early warning sensing devices, wherein each mudslide monitoring early warning sensing device is taken as a MESH network node, the RTU has a concentrator for data collection integrated therein, and the RTU is in wireless communication connection with all the mudslide monitoring early warning sensing devices through the concentrator. The wireless self-networking group detection based mudslide early warning sensing device, system and method, based on multiple sensors, cooperatively realize mudslide monitoring early warning and have remarkable social benefits.

Description

technical field [0001] The invention relates to a sensor device, system and method for detecting debris flow early warning based on a wireless ad hoc network group. Background technique [0002] Debris flow is a geological disaster that occurs in mountainous areas. It is a special torrent containing a large number of sand and stones, which is characterized by suddenness, ferocity and strong destructive power. my country's landforms are complex and diverse, and are dominated by mountains, accounting for about two-thirds of the country's land area. Due to the complex geology and geomorphology of the mountainous area and the East Asian monsoon region, frequent rainstorms, coupled with human behavior, lead to frequent debris flow disasters, which seriously affect the ecological environment and people's livelihood. [0003] The basic research on debris flow and the dynamic monitoring of debris flow must carry out field scientific experiment observation. The traditional mudslide...
