Power distribution management system for after-sales mobile service vehicle and operation method of power distribution management system

Abstract

A power distribution management system for an after-sales mobile service vehicle comprises a circuit breaker Q1, a voltage switching control box U1, an inverter U2, a 380V socket U3, an air compressor M1, an electric drum U4, a generator G1, a pressure switch control box U5, a starter M2, a starting relay K1, an intermediate relay K2, a start-stop switch panel U8, an oil breaker U7 and a storage battery G2, and a start switch S1 and a stop switch S2 are arranged on the start-stop switch panel U8. During operation, starting and stopping of the system are completed by operating the starting switch S1 and the stopping switch S2, 220V or 380V power supply output is selected at the pressure switching control box U1 after starting, and when the 380V power supply is output, starting and stopping of the air compressor M1 are controlled according to opening and closing of the pressure switch control box U5. According to the design, high integration of the generator and the air compressor control system is achieved, and the energy-saving effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of power supply distribution for power supply vehicles, and in particular relates to a power supply distribution management system for after-sales mobile service vehicles and an operation method thereof, which are suitable for improving the degree of system integration and energy saving and emission reduction. Background technique [0002] The control systems of the engine and the air compressor on the existing after-sales mobile service vehicle are independent of each other, the control process is cumbersome, the work efficiency is low, and there is no output voltage display function, the staff is easy to misuse without knowing it, and the air compressor When the system starts and stops, it is vulnerable to current shock, which poses a threat to the safety of the entire circuit. In addition, the low-voltage output of the generator cannot be adjusted independently, which may easily cause over-discharge and ov...

[0002] The control systems of the engine and the air compressor on the existing after-sales mobile service vehicle are independent of each other, the control process is cumbersome, the work efficiency is low, and there is no output voltage display function, the staff is easy to misuse without knowing it, and the air compressor When the system starts and stops, it is vulnerable to current shock, which poses a threat to the safety of the entire circuit. In addition, the low-voltage output of the generator cannot be adjusted independently, which may easily cause over-discharge and over-charge of the battery and shorten the battery life.
