Intelligent cabin temperature alarm system of a passenger car and passenger car

Abstract

The invention discloses an intelligent cabin temperature alarm system of a passenger car and the passenger car. The intelligent cabin temperature system of the passenger car comprises a plurality of temperature sensors, CAN instruments, a whole car controller, a smoke collecting device, smoke sensors and fire extinguishers which are correspondingly arranged in all cabins of the passenger car. Thetemperature sensor is electrically connected with the CAN instrument through a wire harness. An output port of the CAN instrument is electrically connected with an input port of a vehicle control unitthrough a wire harness; an output port of the vehicle control unit is electrically connected with an input port of a smoke collection device and an input port of a fire extinguisher through a wire harness, and the smoke collection device and the smoke sensor can be electrically connected through a wire harness. According to the passenger car intelligent cabin temperature monitoring system, the temperature of each cabin of a passenger car can be accurately and reliably monitored in real time, fire disasters are prevented, and meanwhile, a fire extinguisher can be quickly started to extinguishfire when the fire disasters occur, so that the passenger car runs more safely.

Description

technical field [0001] The invention belongs to the technical field of automobile safety technology, and in particular relates to an intelligent cabin temperature alarm system for a passenger car and a passenger car. Background technique [0002] At present, buses are an important means of transportation for people to travel. my country is vigorously advocating the policy of bus priority to solve the problem of urban congestion. The number of urban buses is increasing. In order to achieve energy saving and emission reduction, new energy buses are becoming more and more common. Usually, the passenger car fire protection system includes a control system, a manual start control button, a buzzer and a fire fighting device. When the manual start control button is pressed, a key signal is generated. After receiving the key signal, the control system outputs a control signal to make the buzzer energize and work to send out an alarm signal. At the same time, the fire-fighting device...

AI Technical Summary

Problems solved by technology

[0003] For new energy buses, the power battery compartment and the engine compartment are the parts that are most likely to catch fire. With the existing vehicle fire protection system, it is only necessary to first judge whether there is a fire through observation, and then press the manual start control button to start the fire protection device. The actual temperature of the power battery compartment and the engine compartment cannot be detected, so there will be potential safety hazards. At the same time, the driver or staff may forget to press the manual start control button in an emergency, so that the fire cannot be stopped in time. It will greatly delay the escape time of passengers, greatly affect the safety of passenger cars, and pose a serious threat to people's lives.
