If the monitoring node does not receive the broadcast signal sent by the master module within the preset time, the monitoring node indicates that the fault caused by the damage or aging of the antenna in the master module cannot be repaired by controlling the restarting of the master module, and the standby slave module needs to be started to replace the master module to broadcast outwards. If the monitoring node receives the broadcast signal sent by the main module within the preset time, the monitoring node indicates that the system is reset by restarting the main module due to the failure caused by the problem of the broadcast signal sending system of the main module, and then the broadcast signal sending system of the main module can be restored to be normal. At this time, the antenna in the master module can normally transmit the broadcast signal, and the standby slave module is not required to be started to replace the master module. The preset time can be set according to the needs, for example, the preset time can be 2s. After the failure of the antenna of the main module is judged, the failure type of the antenna of the main module is judged by restarting the main module, and corresponding operation is performed, so that the waste of resources is avoided.

Specifically, after the monitoring node determines that the antenna of the master module has a fault, the master module may not be controlled to restart, and the standby slave module is directly started to replace the master module to broadcast outwards.
It should be noted that the standby slave module may be a monitoring node, or the monitoring node is located in a slave module other than the standby slave module. That is, the monitoring node and the standby slave module may be one device that is integrated together, where the standby slave module is the monitoring node, or the monitoring node and the standby slave module may be two physically separated devices, where the standby slave module selects a slave module without monitoring software, that is, selects a slave module other than the monitoring node as the standby slave module. In addition, the main module and the standby slave module keep basic consistency in software logic, so that main and standby switching can be performed at any time, and the response time of switching is reduced.
According to the technical scheme, when the digital key system is started or needs to be detected, a detection program is added, the broadcast signals sent by the antenna in the main module are periodically monitored through the monitoring node to locate the antenna, the radio frequency front end and the system fault of the Bluetooth digital key system, and the normal operation of the Bluetooth digital key system is ensured by directly replacing the standby slave module, so that the problems that in the prior art, the Bluetooth antenna node fails and cannot normally operate, the fault location depends on the mode that the external connection equipment of the system prompts unsuccessful connection or the fault code extraction and other passive acquisition faults are relied on are solved, the digital key function experience is affected, the user experience loss caused by the faults is relieved, and the reliability of the whole system is improved.
