This paper introduces a design scheme that integrates the control of the charger and the microcomputer monitoring of the DC system. The main components, the basic working principle and the main functions of the microcomputer monitoring control device of the DC system are introduced. The mature technology of the analog control charger is introduced. The control circuit of the charger is improved to realize the local control and remote control of the working mode and on / off. The measurement method of bus parameters is introduced. A simple and practical method of measuring the insulation resistance of busbar to ground is presented. Status display, alarm and printing; given the method of serial communication, to achieve the telemetry, remote information, remote adjustment, remote control
