The design of an embedded intelligent monitoring and control system of the DC power supply based on internetworking

The paper chiefly introduces the system construction and design principle of embedded intelligent monitoring and controlling system of DC power supply based on internetworking. The system is made up of main control module, assistant control module, battery monitor module and insulating resistant monitor module. It is used to monitor all necessary parameters and states of DC power supply such as bus voltages, voltages and inner resistant of battery, insulating resistant of bus and so on. And control power supply system working with the set parameters and in a high efficiency. The interface of internetworking is embedded in the monitoring and controlling system so it is a remote-controlled system. This system keeps the DC power supply system work in high stability, reliability and safety.
