Abstract

The invention provides a large-scale fire monitoring method and system based on time difference measurement and calculation. The fire monitoring method comprises the following steps: dividing a to-be-monitored area into a plurality of sub-areas according to area information of the to-be-monitored target area; carrying out data initialization, configuring a plurality of signal receiving devices andat least one signal transmitting device for each subarea, and obtaining a communication time difference between the signal receiving devices and the signal transmitting devices and transmitting information of the signal transmitting devices received by the signal receiving devices in each subarea; acquiring position information of each signal transmitting device according to the coordinate information of each signal receiving device and the communication time difference; and acquiring a live wire leading edge fitting curve and a live wire pushing speed according to the position information ofeach signal transmitting device. According to the invention, the fire development trend is fed back in real time.

Description

technical field [0001] The invention relates to the application field of forest fire safety, in particular to a large-scale fire monitoring method and system based on time difference measurement and calculation. Background technique [0002] The prevention and monitoring of large-scale fires is an important issue in the field of disaster protection. Once a large-scale fire occurs, the loss of life and property caused is incalculable. The prevention and monitoring of large-scale fires cannot be ignored. Once such a large fire occurs, it cannot be extinguished in a short time. The method of dividing the fire is often used to prevent the fire from spreading. This requires a real-time observation of the trend, speed, and fire area of ​​the fire. The present invention provides such observation data for rescue experts through a method based on time difference calculation, thereby minimizing the loss of life and property. [0003] Existing fire monitoring methods generally use sat...
