The door management method according to claim 6, wherein the door management method further comprises: when the verification fails, obtaining a first number of verification times; comparing the first number of verification times with a first preset number of verification times; and when the first number of verification times is greater than or equal to the first preset number of verification times, determining that the door body does not meet the closing condition, and sending second alarm information to a server of the unattended battery swap station system; or when the first number of verification times is less than the first preset number of verification times, performing, by the AI edge computing unit, verification on the result that the monitoring device and its communication are normal.
The door management method according to claim 5, 6 or 7, wherein the management method further comprises: when the monitoring device or the communication of the monitoring device or both are abnormal, sending third alarm information to a server of the unattended battery swap station system.
The door management method according to any one of claims 3 to 8, wherein after the step of "when there are vehicles, persons, and/or animals in the unattended battery swap station, controlling the door control device to close the door body", the method further comprises: sending, by the controller, a second instruction to the AI edge computing unit, so that the AI edge computing unit determines, based on the second instruction, whether the door body is in a closed state; and when the door body is in the closed state, sending a third instruction to a server of the unattended battery swap station system.
The door management method according to claim 9, wherein the door management method further comprises: when the door body is in an open state, obtaining a closing time of the door body; comparing the closing time of the door body with a first preset time; and when the closing time is greater than or equal to the first preset time, sending fourth alarm information to the server; or when the closing time is less than the first preset time, controlling the door control device to close the door body.

Description

The present application claims priority of CN patent application 202310232554.3 filed on March 7, 2023 with the title "Door management method for unattended battery swap station system". Technical Field The disclosure relates to the technical field of battery swap stations, and in particular to a door management method for an unattended battery swap station system. Background Art As the new energy vehicle market continues to heat up, new energy users are also increasing day by day. With the expansion of the user base, how to replenish electric energy conveniently and quickly has become a focus of user attention. In this context, battery swap stations have emerged, which can easily and quickly replenish energy for electric vehicles by replacing traction batteries. At present, due to the increasing number of battery swap stations and the increasing labor costs, unattended battery swap stations have become an important development direction for battery swap stations. Such a battery swap station can get rid of the problem of service personnel being on duty 24 hours a day and realize battery swapping. However, a door of the current unattended battery swap station controls to determine whether to close a door body only through a sensor mounted near the door, without considering specific conditions in the station, which poses a safety hazard. CN 114 701 390 A discloses the technical field of safety protection, in particular to a safety protection method, system, medium and device for a battery charging and replacing station and the battery charging and replacing station. CN 114 906 005 A discloses a system and a method for pile-station integrated linkage calling energy supplement.
