Fire hazard early-warning system based on online monitoring of cable

Abstract

The invention discloses a fire hazard early-warning system based on the online monitoring of a cable, and the system mainly comprises a main unit system, a monitoring part, and an early-warning adjustment part. The online monitoring of the aging and damage conditions of all cables on a site is carried out through the monitoring part, and the temperature of a power distribution box and a frame generation signal are gathered to the main unit system for arrangement and analysis. If a potential electrical fire risk is monitored, the early-warning adjustment part transmits a fire early-warning signal to an onsite radio and an alarm, and the position of the people on the site is determined through wifi, and then an evacuation scheme is formulated at the highest speed. The system achieves the accurate monitoring of electrical fire fundamentally, carries out the early warning against the electrical fire, is accurate in information, can achieve the quickest evacuation of the people when fire happens, avoids secondary accidents, and is safe and effective.

Description

Technical field [0001] Involved in the field of intelligent monitoring systems. technical background [0002] With the development of modern science and technology, various electrical equipment has been extensively developed and utilized accordingly. Large shopping malls, office buildings, residential areas and other places with many cables are areas with a high incidence of electrical fires. At the same time, such places are also densely populated and economically concentrated places. Once a fire accident occurs, the casualties and economic losses caused cannot be estimated. Therefore, fire monitoring systems that can prevent and provide effective measures in time are becoming more and more important. The traditional fire monitoring and alarm system monitors the fire before it can be forecasted for the purpose of reducing losses, while the electrical fire monitoring system provides early warning before the fire occurs, with the purpose of avoiding losses.

Problems solved by technology

The electrical fire monitoring system that is generally implemented now basically detects the residual current signal of the equipment cable, the power quality and temperature value in the circuit through sensors, and then cooperates with on-site fire detectors to infer and predict the occurrence of electrical fires. Although this method is perfect, However, the data collected in the detection of cables is too indirect, which is likely to cause false alarms; for example, the residual current of the cable, regardless of whether the circuit has a fault, the residual current is fixed, and the method of judging the circuit fault with the residual current as a parameter does not Not accurate enough
