Description
Technical Field
The invention belongs to the technical field of intelligent fire fighting, and particularly relates to a method and a system for identifying and protecting potential safety hazards of electric leakage.
Background
The current internal leakage of the building is mainly subjected to safety protection through a fuse short-circuit measure, and the detection of electrical fire is mainly applied to the industrial field. The existing electrical fire detection technology, for example, chinese patent "an electrical fire monitoring system" with publication number CN209746754U, proposes to collect current information of 220V mains supply, and the collected data is processed and converted by a signal processing module before being sent to a central processing unit, so as to realize all-round monitoring and early warning of electrical fire risk coefficients. Chinese patent publication CN100546145C, "voltage surge protection device", proposes that a protection module comprises at least one protection element for protection against voltage surges and at least one protection element separation device connected to the protection element separation device, so that an electrical and/or mechanical separation is generated after an increase in temperature and/or current, which indicates a malfunction of the protection element. The existing electric fire early warning technology in the building, for example, chinese patent "an intelligent fire protection management system and management method with escape route" with CN110170137A, proposes that an intelligent power management terminal contains three modules of equipment monitoring, line monitoring, and alarm protection, and performs monitoring of multiple electrical parameters and line temperature, and once the line is short-circuited or a fire causes abnormal monitoring data, the intelligent power management terminal automatically cuts off the line power supply, and also includes a management method of the intelligent fire protection management system, including equipment patrol management, equipment maintenance management, equipment alarm patrol management, fire alarm management, escape route planning management, and escape route push management.
The technology mainly carries out the prevention and control of the electrical fire in the modes of short circuit monitoring, mechanical separation and data abnormity judgment, and the algorithms are established on the basis of short circuit of a line and fuse blowout. However, when the fuse is abnormal in working state, it is difficult to warn the electric fire, and once the electric fire occurs inside the building, it is difficult for people inside the building to escape effectively due to the dark and smoke environment caused by power failure and fire, thus bringing the danger to life and property.
At present, no technical scheme for effectively identifying and protecting the potential safety hazard of electric leakage in the building exists. Therefore, a method and a system for identifying and protecting the potential safety hazard of electric leakage are provided.
