A device management method of the present application is described in detail below.

As shown in fig. 2, fig. 2 is a schematic flowchart of a device management method according to an exemplary embodiment of the present application, and taking the method as an example for being applied to the master controller 101 in fig. 1, the method may include the following steps:

s201, sending a heartbeat command to a peripheral controller of each expansion device through a first communication link.

The first communication link is an interactive host channel between the main controller and a peripheral controller of the expansion device, and may be used to transmit an operation instruction (e.g., a reset control instruction) and transmit data, and the first communication link may be a data transmission bus such as I2C, SMBus. The heartbeat command is used for instructing the peripheral controller of the expansion device to send the device state data to the main controller.

The main controller needs to detect the mounted expansion device on the first communication link before sending the heartbeat command to the peripheral controller of each expansion device periodically through the first communication link. One or more clamping grooves can be formed around the main control unit main board for inserting the expansion equipment, and if the expansion equipment is inserted into the corresponding clamping groove, the expansion equipment is externally connected to the main control unit main board, namely, the expansion equipment is mounted on the first communication link.

The reset control circuit of the target expansion equipment is connected with the reset control end of the peripheral controller of the target expansion equipment. The target expansion device is an expansion device corresponding to the peripheral controller which does not send device state data to the main controller.

And when the main controller does not receive the equipment state data sent by the peripheral controller of the expansion equipment within the preset time length, the main controller is used as the peripheral controller of the target expansion equipment in one or more expansion equipments. At the moment, the main controller generates a first reset control instruction and sends the first reset control instruction to the reset control circuit of the target expansion equipment, the reset control circuit of the target expansion equipment responds to the first reset control instruction to generate a reset trigger signal, and the reset trigger signal is sent to the reset control end of the peripheral controller of the target expansion equipment, so that the peripheral controller of the target expansion equipment executes reset operation.

In some cases, for example, when the peripheral controller is hung up, the peripheral controller may still not respond to the heartbeat command sent by the main controller after the peripheral controller of the target expansion device performs the reset operation, and therefore, manual intervention is required to perform fault handling on the peripheral controller. Based on this, as shown in fig. 3, fig. 3 is a schematic flowchart of a device management method provided in another exemplary embodiment of the present application, and taking the method as an example for being applied to the main controller 101 in fig. 1, the method may include the following steps:
