Temperature and smoke joint control fire extinguishing circuit for bus power battery cabin

Abstract

The invention discloses a temperature and smoke joint control fire extinguishing circuit for a bus power battery cabin. The circuit comprises an on-board 24-V power supply, a fire early-warning controller, an automatic fire extinguisher, a temperature detector, a smoke detector, a starting relay, a manual starting button, an audible and visual alarm, a fire extinguisher status indicator lamp and a remote monitoring terminal. The on-board 24-V power supply, the automatic fire extinguisher, the temperature detector, the smoke detector, the starting relay and the remote monitoring terminal are connected with the fire early-warning controller through a circuit. The remote monitoring terminal transmits information to the remote monitoring platform through a GRPS, and records and stores the information. The temperature and smoke joint control fire extinguishing circuit for the bus power battery cabin is used for carrying out early warning, prevention and fire extinguishing in advance when the temperature of a power battery is increased sharply and a large amount of smoke is produced before open fire occurs, and more escape time is won for passengers.

Description

technical field [0001] The invention relates to a temperature and smoke joint control fire extinguishing circuit for a power battery compartment of a passenger car. Background technique [0002] The fire safety protection and early warning of the power battery compartment of new energy buses is an important safety field. At present, most of the power battery compartments of new energy buses still use the traditional fire extinguisher control circuit. The traditional fire extinguisher control circuit automatically extinguishes the fire according to the temperature and the thermal line. The evacuation of personnel cannot play the role of early warning. However, if there is an open flame in the power battery of a bus, the fire will grow very fast, and it will be very difficult to extinguish the fire. This requires early warning and preventive fire extinguishing before the open fire in the power battery, so as to win more escape time for passengers. Contents of the invention ...
