Dangerous goods warehouse indoor positioning and emergency evacuation system based on wireless sensor network

Abstract

The invention belongs to the field of indoor environment detection, and discloses a dangerous goods warehouse indoor positioning and emergency evacuation system based on a wireless sensor network. Thedangerous goods data are collected through a dangerous goods monitoring formula; the dangerous goods real-time data monitored by the floor is received, and the received data is transmitted to a comprehensive control platform in a wirelessly mode; the door, the window and the fire extinguisher in the warehouse are controlled to be started; meanwhile, the position of the dangerous goods is positioned and warned; the system includes a fire hazard detection module, a ZigBee module, an infrared pyroelectric detection sensor, a GSM alarm and a GPS positioning module. The wireless sensor network isestablished by adopting a Zigbee protocol, the detection node has a self-networking function, and dynamic addition of the network can be realized; the expandability is strong, and the device can add corresponding functions according to actual requirements, and can be realized by only adding the corresponding terminal node and modifying the corresponding control program.

Description

technical field [0001] The invention belongs to the field of indoor environment detection, in particular to an indoor positioning and emergency evacuation system of a dangerous goods warehouse based on a wireless sensor network. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Fires are a serious threat to people's lives and properties. The number of fire deaths in China is astonishing every year. According to statistics, the average annual loss of fires in my country is nearly 20 billion yuan, and more than 2,300 people are killed or injured. [0004] The traditional fire alarm and linkage system is relatively simple, focusing on fire detection and alarm, ventilation and smoke exhaust, and sprinkler fire extinguishing. It does not provide an optimized escape route and cannot guide people to escape safely. However, dangerous goods warehouses are used to store flammable, explosive, corrosive, poisonou...
