Equipment network access method and device based on CAN bus, equipment and medium

The invention provides an equipment network access method and device based on a CAN bus, equipment and a medium, and the method comprises the steps: determining whether there is a networked CAN device in a controller area network or not when a to-be-networked CAN device is connected with the CAN bus and is powered on; if yes, further determining whether the Baud rate of the CAN device to be accessed to the network is the same as the Baud rate of the controller local area network; and if the two are different, controlling the CAN equipment to be accessed to the network to enter a dormant state and not to access the controller local area network. According to the scheme, when the CAN device already accessed to the network exists in the controller local area network and the baud rate of the CAN device to be accessed to the network is different from the baud rate of the controller local area network, the CAN device to be accessed to the network is controlled to enter the dormant state, so that the safety of the c
