Vehicle battery safety monitoring system

Abstract

The invention discloses a vehicle battery safety monitoring system. The vehicle battery safety monitoring system includes a battery monitoring unit, a communication unit, a sensor monitoring unit, an alarm unit, a communication line and a train line. The battery monitoring unit is used to measure the working condition parameters of the vehicle battery and send them to the communication unit, and the communication unit transmits them to the warning unit through the communication line. The sensing and monitoring unit is used to detect the environmental physical quantity of the working environment where the vehicle battery is located and transmit it to the warning unit via the train line. The warning unit generates and outputs warning information according to the received environmental physical quantity and working condition parameters. In the vehicle battery safety monitoring system of the present invention, a heterogeneous structure fault tolerance mechanism is designed in the sampling link, data transmission link and warning link, which can reliably monitor the failure or risk of failure of the battery and give an alarm in time, significantly improving battery safety monitoring. Reliability ensures the safety of vehicles and passengers in emergency situations.

Description

technical field [0001] The invention relates to a vehicle battery safety monitoring system. Background technique [0002] Many existing rail transit vehicles are equipped with accumulators for providing backup power supply. When the equipment is running normally, the vehicle introduces AC or DC power from the catenary, and then the traction system generates traction power, and the auxiliary inverter system generates auxiliary power, such as DC 110V auxiliary power. When the catenary fails or the auxiliary inverter system of the train fails to provide DC power supply for the train, the battery will provide a reliable backup power supply for the train to support the normal operation of the compartment emergency lighting, air conditioning emergency ventilation, train control and communication systems . Therefore, the reliable operation of batteries has become the basic guarantee for the safe operation of vehicles, especially trains. It is directly related to the personal safe...
