The present invention relates to the technical field of direct current power supply, and discloses a power supply apparatus based on a CAN bus. The apparatus includes: a main power conversion module,a power distribution module, a centralized control module, and a switch control module. The main power conversion module is connected to the centralized control module by using the CAN bus. The main power conversion module is configured to convert an input voltage into multiple channels of isolated direct current voltages, and output the direct current voltages to the power distribution module tosupply power to a plurality of electrical devices. The power distribution module includes a plurality of main output switches to control the plurality of electrical devices to switch between power onand power off. The centralized control module is connected to the switch control module, and is configured to: receive a user input instruction and output a switch control signal to the switch controlmodule according to the user input instruction. The switch control module is connected to the power distribution module, and is configured to control closing and opening of the plurality of main output switches based on the switch control signal. Therefore, a safe and reliable digital direct current power supply apparatus with a simple structure and good system expansion is implemented in the present invention.
Description
technical field [0001] The invention relates to the technical field of DC power supply, in particular to a CAN bus-based power supply device. Background technique [0002] DC power supply devices are widely used in various systems to provide power for equipment in the system. Early DC power supply devices used analog technology, the output was controlled by manual switches, and instruments were used to display information such as voltage and current, but this method was not conducive to the collection and centralized control of equipment status information. With the development of technology, the current DC power supply device has adopted digital technology for centralized control, but each component module and the centralized control module / host computer mostly use serial port communication, resulting in intricate connection lines between modules and many interfaces of the centralized control module. Expansion, bulky equipment, high failure rate. Contents of the inventio...
