Embodiment Construction

[0020] A mud-rock flow monitoring and early warning system combining GPRS and ZigBee networks, comprising the following steps:

[0021] (1) In areas where debris flow may occur, a large number of debris flow sensors are arranged to collect parameter information related to debris flow in the environment. These sensors are attached to the zigbee network, and data transmission and control are realized through the zigbee network to form a zigbee sensor network.

[0022] The sensor nodes are mainly attached to the zigbee terminal, the terminal data is transmitted to the coordinator through the router, the data format is converted through the zigbee / GPRS gateway, and finally transmitted to the remote control center through the GPRS network. At the same time, the remote control center can transmit commands to the zigbee network through the reverse link and issue detection tasks.

[0023] (2) The sensor network adopts tree topology. In order to enhance the reliability of data transm...

Abstract

The invention discloses a GPRS and ZigBee network-based debris flow monitoring and early warning system. According to the system of the invention, sensor nodes can be linked to a variety of kinds of debris flow sensors; data monitored by the sensors pass through a gateway and then are preliminarily processed through ARM equipment; processed data are connected into an IP network through GPRS connection and then are transmitted to a remote data and management center for processing and storing the data; an administrator configures a sensor network through a reverse link, releases a monitoring task and collects monitoring data; after a PC receives the data, upper computer software immediately processes and analyzes the data, and obtains data information of monitored debris flows according to the critical values of key factors, and therefore, the debris flows can be monitored, and debris flow early warning signals can be timely emitted when a disaster risk occurs; monitoring personnel switch on an image acquisition system at the ARM equipment in real time; and after the calculation of an efficient image compression algorithm, image information of a site where a disaster is to occur is transmitted to the PC or a monitoring center through a GPRS wireless network.

Description

technical field [0001] The invention belongs to the technical field of geological disaster safety, in particular to a method for real-time monitoring and early warning of debris flow disasters realized by using ZigBee and GPRS network technologies. Background technique [0002] my country is one of the countries most seriously affected by debris flows. Establishing a sound early-warning system for debris flows has become the focus of experts and scholars in related research fields to enable early warning of disasters, thereby reducing the destructive power of natural disasters and protecting people's lives and property. consensus. However, the location where the debris flow occurs is generally relatively remote, lack of power supply, and inconvenient communication, which brings huge challenges to related monitoring. [0003] Due to the characteristics of low power consumption, low cost and high capacity of ZigBee network, this project proposes a monitoring system based on Zi...
