Intelligent power control system and power control circuit

Abstract

The invention provides an intelligent power control system and a power control circuit. A controller, a power supply, a sampler, a large power controller and a small power controller are included. A pure electronic control method is adopted, and a PCB design and an appearance heat dissipation design are cooperated so that a large power driving capability is reached. Simultaneously, through sampling an output current in real time and cooperating with an input control state, state information of each path of power channel which carries out open circuit, a short circuit, overcurrent and the like can be acquired. The information is sent to a display unit through a CAN bus so as to carry out real-time state display and alarm. On a power control device, through an LED, a work state of power output is directly indicated. When the overcurrent and the short circuit are generated, an output channel can be automatically cut off so as to prevent a safety accident. The system and the circuit are safe, any components do not need to be replaced, and once a peripheral fault is overcome, the system and the circuit are automatically recovered to be normal and there is no use cost.

Description

technical field [0001] The invention relates to an intelligent power control system and a power control circuit thereof. Background technique [0002] One of the current power control devices is composed of fuses and relays, and there is no working status indication. After the fuses or relays fail, they need to be checked one by one, which is time-consuming and laborious. The other is also composed of fuses and relays, but the output status is increased. For detection, these status information can be sent to the bus through the CAN bus, and these statuses can be displayed on the LCD. Once the fuse burns or the relay fails, it can be easily replaced, but it cannot perform status indications such as overcurrent and output open circuit. And it cannot be protected by itself, and there is work to replace insurance and relays, which is time-consuming and expensive. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides ...
