Abstract

The invention belongs to the technical field of detectors and particularly relates to a detector for electric leakage fire monitoring. The detector for electric leakage fire monitoring, good in monitoring and detecting effect and low in cost, comprises a single-chip microcomputer, a temperature sensor, a smog sensor, a gas sensor, a leakage current transformer, an A/D conditioning circuit, an audible-visual alarm, an EEPROM (Electrical Erasable Programmable Read Only Memory), a keyboard, an LCD (Liquid Crystal Display), an RS485 bus, a clock, a releasing controller and a fire-fighting interface. The structural key points of the detector are that ports of the single-chip microcomputer are respectively connected with the temperature sensor, the smog sensor, the gas sensor, the A/D conditioning circuit, the audible-visual alarm, the EEPROM, the keyboard, the LCD, the RS485 bus, the clock, the releasing controller and the fire-fighting interface; and the A/D conditioning circuit is connected with the leakage current transformer.

Description

technical field [0001] The invention belongs to the technical field of detectors, in particular to a leakage fire monitoring detector. Background technique [0002] In recent years, electrical fires have remained high. In order to curb the rising trend of electrical fires, relevant government departments have successively formulated or revised relevant standards and regulations, requiring the installation of leakage fire alarm systems in buildings. The definition of leakage fire alarm system in GB13955-2005 "Installation and Operation of Residual Current Action Protection Device" is: residual current action electrical fire monitoring system refers to transformers, residual current detectors, alarms or The controller constitutes a device for real-time monitoring of electrical fires and implementing an alarm or cutting off the power supply. The new standard GB 14287-2005 "Electrical Fire Monitoring System" implemented on June 1, 2006 changed the name of "Fire Protection Leaka...
