when the first timer 211 counts for a first predetermined time and the second timer 212 counts for a second predetermined time, the second door 21 is controlled to be unlocked so that the second door 21 can be opened.
Since there may be differences in the functions of the regions, or different regions may have different requirements for the environment and the time required to restore the predetermined state, the corresponding timers may count for different times, i.e., different predetermined durations. By using the first timer 211 of the second door 21 corresponding to the third timer of the previous door and the second timer 212 corresponding to the fourth timer of the subsequent door, the second door 21 can be unlocked only when the first timer 211 reaches the first predetermined time and the second timer 212 reaches the second predetermined time, so that the corresponding second door 21 can be opened.
Preferably, the first predetermined time period is less than the second predetermined time period.
Specifically, the method further comprises:
when the first door 11 is opened, the second door 21 adjacent thereto is controlled to be locked.
The first door 11 is opened and the second door 21 adjacent to the first door is locked, so that cross contamination caused by communication between three adjacent areas is avoided.

The first door 11 is closed and locked after being opened, and the corresponding areas cannot be communicated before the environment in the areas is recovered to the preset state by timing through the timer, so that cross contamination to other areas is avoided or the areas are prevented from being polluted again before the environment is not recovered.
When the initial timer 111 counts for a first predetermined time, the first door 11 is controlled to be unlocked so that the first door 11 can be opened.
Specifically, the method further comprises:
when the second door 21 adjacent to the third door 31 is opened, the locking of the previous door adjacent to the second door and the third door 31 is controlled.

When the end timer 311 reaches a second predetermined time period, the third door 31 is controlled to be unlocked so that the third door 31 can be opened.
In this embodiment, the opening of the third door 31 does not affect the locking or unlocking of the other doors, and the closing of the third door 31 after opening does not cause any timer to be reset. Since the third door 31 connects the intermediate zone 20 and the end zone 30, the environmental conditions between the two zones are similar, and thus the intermediate zone 20 does not need to be restored after the two zones communicate with each other.
It should be mentioned that there is no chronological relationship between the above steps, and those skilled in the art can solve the technical problems in the present application by exchanging the order of the steps.

It should be understood that the definitions of the zones in fig. 1-2 are identified by enclosed spaces, and that the enclosures are not defining features of the zone structure, but are added for convenience in explaining the concept of zones, e.g., the initial zone 10 and the final zone 30 in fig. 1 are not completely enclosed.
The present invention also provides an opening and closing control method of the passage 100 described in embodiment 1, the method including the steps of:
when the first door 11 is opened, the second door 21 adjacent thereto is controlled to be locked.

When the initial timer 111 counts for a first predetermined time, the first door 11 is controlled to be unlocked so that the first door 11 can be opened.
When the second door 21 is opened, the first door 11 and the third door 31 are controlled to be locked.
When the second door 21 is closed and locked after being opened, controlling a first timer 211 and a second timer 212 corresponding to the second door 21, an initial timer 111 corresponding to the first door 11, and an end timer 311 corresponding to the third door 31 to count again, wherein the initial timer 111 counts time in synchronization with the first timer 211, and the second timer 212 counts time in synchronization with the end timer 311.
When the first timer 211 counts for a first predetermined time and the second timer 212 counts for a second predetermined time, controlling the second door 21 to be unlocked so that the second door 21 can be opened;
controlling the third door 31 to be unlocked to enable the third door 31 to be opened when the end timer 311 reaches a second predetermined time period;
