Design And Research Of Forest-fire Warning System Of Transmission Line

With the development of society,network has become an important guarantee for modern social development and economic progress,the coverage is more and more wide,covering not only the developed area,also has been extended to the remote mountainous areas of complex geology and climate.As a result of fire caused by line trip outage occurs frequently,to the safety and stability of the grid operation brings great hidden danger.The purpose of this paper is to study how to apply the mountain fire early warning technology to prevent the trip accident caused by fire.The main work and achievements of this paper are as follows:1 study the means and methods of mountain fire early warning.First of all,the mechanism of line trip and cause of fires are analyzed;secondly,through the concrete case of Hubei area fire trip analysis,the fire warning system must have fire warning and live video display two functions,and further clarify the design requirements of fire warning system;finally through the concrete analysis of the advantages and disadvantages of different fires early warning method,determined by a way of active warning early warning of fire plan.2 The overall design scheme of mountain fire warning system is put forward.Based on the aim and principle of the design scheme of the fire alarm system,the composition and working mode of the system are studied.This paper analyzes the technical difficulties of the application of the system,and finally puts forward the overall design scheme of the fire alarm system.The practical application shows that the system can overcome the influence of the outside environment and realize the accurate detection and recognition of the fire.3 detailed design of each subsystem of the fire alarm system.Starting from the fire recognition acquisition,were studied based on 4G remote communication network information transmission method,the solar power system power supply principle,online video monitoring center system center software system structure and management system.Through the use of fire location technology to collect information to confirm the fire forest-fire,the use of 4G technology to transmit data,the solar power technology to all-weather power,DLP large screen wall and centralized monitoring system based on distributed sensing information processing,completed the design of all the components of the system.Finally,it shows that the design scheme can realize the early warning of the surrounding fire around the clock,which provides the data basis for the operation of the line.
