Abstract
The utility model relates to a temperature measuring type electric fire detector. The electric fire detector comprises a temperature signal collecting circuit and a single-chip microcomputer control circuit. Output signals of the temperature signal collecting circuit are transmitted to the single-chip microcomputer control circuit by an A/D data conversion circuit. Output signals of the single-chip microcomputer control circuit are sent to a Zigbee wireless module circuit and a voice alarm circuit. When the temperature signal collecting circuit collects a signal that the surface of a cable is over-temperatured, the signal is sent to the single-chip microcomputer control circuit after pasting through the A/D data conversion circuit, the single-chip microcomputer control circuit determines the signal and sends a control signal, then the control signal is sent by the Zigbee wireless module circuit, and a data alarm center displays alarm information such as alarm addresses and locations when the data alarm center receives an alarm signal, so that safety monitoring and early warming are combined. The electric fire detector provided by the utility model is characterized by simple network, wireless transmission and low engineering cost.
