Abstract

The invention discloses a multi-channel digital power supply architecture based on a secondary CAN bus and a program secondary online updating method. The method comprises the following steps: establishing the multi-channel digital power supply architecture of the secondary CAN bus; a digital power supply module on an internal bus is no longer directly connected to an external CAN bus network, that is, the digital power supply module of each channel in the power supply is not provided with an external interface, a data summarization and instruction forwarding module is installed in each power supply, the data summarization and instruction forwarding module is used for summarizing internal CAN bus data, and the data summarization and instruction forwarding module is used for forwarding the data to the external CAN bus network. The data collection and instruction forwarding module is used for collecting and forwarding data through an external CAN interface, receiving data of the external CAN interface and forwarding the data to an internal CAN network, the data collection and instruction forwarding module is used as a transfer bridge for communicating internal and external two-stage CAN buses, secondary forwarding of the data is completed by using the data collection and instruction forwarding module, and program updating of network nodes of the internal CAN bus is realized.
