considering that the prior art that the communication connection between the controller host and the cloud platform is realized through one communication link can cause the controller host to disconnect from the cloud platform after the communication link fails, thereby interrupting parking service, detecting the parking service after the interruption and maintaining the parking service when the communication link between the controller host and the cloud platform fails, and continuously interrupting the parking service.
Specifically, when the controller host in the parking lot and the cloud platform are connected and communicated through the main communication link, whether the main communication link between the controller host and the cloud platform works normally or not can be detected, so that the abnormal condition that the main communication link does not work normally can be timely found through active detection. When the detection is performed, if it is determined that the main communication link between the controller host and the cloud platform is in normal operation, step S11 may be continuously performed to continuously detect the main communication link, and if it is determined that the main communication link between the controller host and the cloud platform is not in normal operation, step S12 may be performed.
S12: the interface of the primary communication link is closed and a target secondary link is selected from the at least one secondary link.
When it is determined that the main communication link between the controller host and the cloud platform does not work normally, the interface of the main communication link may be closed, that is, an unnecessary interface may be closed, and at the same time, one auxiliary link may be selected from at least one auxiliary link set in advance between the controller host and the cloud platform as a target auxiliary link, specifically, random selection may be performed, or each auxiliary link may be numbered in advance, and selection may be performed in order of from small to large or from large to small.
It should be noted that, when only one auxiliary link is provided, the auxiliary link may be directly used as a target auxiliary link, and in order to reduce the running cost of the parking lot, one auxiliary link may be preferably provided, specifically, fig. 2 may be referred to, which shows a connection schematic diagram between the controller host and the cloud platform provided in the embodiment of the present application, and in fig. 2, one main communication link and one auxiliary link are provided between the controller host and the cloud platform.

In addition, because the communication link between the controller host and the cloud platform is switched without human intervention, the communication cost of the controller host and the cloud platform can be reduced, and the labor cost of parking lot operation is reduced.
It should be noted that after the controller host communicates with the cloud platform through the target auxiliary link according to the routing table and the default route, whether the target auxiliary link works normally or not may be detected, and when the target auxiliary link does not work normally, the controller host may switch to the main communication link or any other auxiliary link (when the main communication link is normal, the controller host may switch to the main communication link directly, and when the main communication link is abnormal, the controller host may switch to any other auxiliary link) so that the controller host may communicate with the cloud platform continuously, thereby avoiding interruption of the parking service.
According to the technical scheme, whether the main communication link between the controller host and the cloud platform in the parking lot works normally is detected, the interface of the main communication link is closed when the main communication link does not work normally is detected, the target auxiliary link is selected from the auxiliary links, the target auxiliary link is opened, the routing table and the default route are updated, so that the controller host can communicate with the cloud platform through the target auxiliary link, namely, the abnormal condition that the main communication link does not work normally can be timely found through the active detection of the main communication link, and the auxiliary link is utilized to ensure the normal connection and normal communication between the controller host and the cloud platform when the main communication link does not work normally, so that the controller host and the cloud platform are prevented from being interrupted due to the fact that the main communication link does not work normally, the interruption of parking service is avoided as much as possible, and the running stability and reliability of the parking lot are improved.
