Intelligent monitoring unit for vehicle-mounted three-phase alternating current power supply equipment

Abstract

The invention discloses an intelligent monitoring unit for vehicle-mounted three-phase alternating current power supply equipment. The intelligent monitoring unit comprises a power mother board and a control panel, wherein the power mother board comprises an auxiliary power supply unit, a lightning protection unit and a protection action executing unit; the control panel comprises a three-phase alternating current detecting unit, a three-phase alternating voltage detecting unit, an electric leakage detecting unit, a main control unit and a ground state detecting unit, wherein the ground state detecting unit adopts dual-ground detection, the control panel integrates a CAN (Controller Area Network) bus communication function and a 485 serial bus communication function. The whole intelligent monitoring unit has multiple functions of lightning protection, three-phase alternating current overcurrent, short circuit, electric leakage protection, three-phase alternating voltage overvoltage, undervoltage protection, ground state detection protection and the like, and provides a safer driving environment for a vehicle driving operator.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a monitoring device used for three-phase AC power supply equipment. Background technique [0002] At present, in the field of communication industry, three-phase AC power distribution equipment generally adopts the traditional power protection form, such as the combination of circuit breaker and lightning protection module to form AC power distribution equipment, which is used to realize power distribution, and implement overload, circuit breaker protection. [0003] In the vehicle power supply system, the vehicle smart grid includes the vehicle power supply to provide electric energy; the smart grid control unit is connected to the vehicle power supply, and can complete voltage conversion, battery parameter monitoring, battery state estimation, and overcurrent protection through the control unit. However, the traditional protection action execution unit only has overload, short circuit or...
