Earthquake emergency disaster prevention method and system based on Internet of things

Abstract

The invention discloses an earthquake emergency disaster prevention method and system based on the Internet of Things. The method includes the following steps: S1, a sensing node uses a three-axis acceleration sensor to record seismic wave data and judges to obtain a judgment result; S2, an embedded gateway obtains the Judging the results and using the principle of minority obeying the majority to make earthquake emergency decision; S3, if the earthquake reaches a dangerous level, the embedded gateway sends emergency instructions to the execution node, and the execution node uses relays and gas solenoid valves to automatically cut off the circuit and gas circuit. In the present invention, the execution node uses the Internet of Things with self-organizing properties to automatically cut off the electric circuit and gas path in real time when the earthquake reaches a dangerous level, thereby effectively preventing the occurrence of secondary earthquake disasters, reducing the loss of earthquake disasters, and enabling residents to Life and property are protected from secondary disasters.

Description

technical field [0001] The invention relates to an earthquake emergency disaster prevention method and system based on the Internet of Things, and belongs to the field of information technology of the Internet of Things. Background technique [0002] The Internet of Things is based on the computer Internet, using sensor networks, RFID, wireless data communication and other technologies to construct an "Internet Of Things" covering everything in the world. In this network, items (commodities) can communicate with each other without human intervention. Its essence is to use radio frequency automatic identification (RFID) technology to realize the automatic identification of items (commodities) and the interconnection and sharing of information through wireless data links and computer Internet. The three characteristics of the Internet of Things are: 1. Wireless communication; 2. Network self-organization; 3. Energy self-supply. [0003] In recent years, there have been many ...

Problems solved by technology

In the existing technology, after the earthquake, the gate of the circuit gas circuit can only be manually closed to prevent electric leakage and air leakage, thereby preventing secondary disasters caused by it. However, due to the collapse of houses after the earthquake, manual removal It is very inconvenient to close the gate of the circuit gas circuit, and this operation will greatly increase the danger of personnel, so the operability is low
