Description

technical field [0001] The invention relates to a power-off delay protection circuit, in particular to a power-off delay protection device for vehicle equipment based on a supercapacitor. Background technique [0002] Rail transit on-board equipment generally works under harsh environmental and electrical conditions. Therefore, the impact of the complex environment in the locomotive on electrical equipment must be considered when designing on-board system equipment. The rail transit train monitoring system is a vehicle-mounted video monitoring system, which is mainly composed of computer communication equipment such as a video server and a system host. When these devices encounter a momentary power failure, the hard disk system will cause the magnetic head to rub against the platter due to insufficient drive motor power, which will cause physical damage to the magnetic track in the long run. Moreover, the data in the computer memory cannot be dynamically refreshed in time w...
