after the output module is connected with the input module of the passive lock in an adaptive mode, the energy storage battery supplies power to the first main control PCB and the locking piece of the passive lock, and based on the position information received by the GPS positioning module, the transmission module receives unlocking information of the passive lock corresponding to the position information and transmits the unlocking information to the second main control PCB, so that the second main control PCB transmits the unlocking information to the first main control PCB.
7. The key of claim 6, wherein the output module comprises a set of conductive terminals electrically connected to the energy storage battery and a set of communication terminals communicatively connected to the second master PCB.
8. A cloud server, adapted to the passive lock of any one of claims 1 to 5 and the key of any one of claims 6 to 7, wherein the cloud server is configured to receive the position information sent by the key, and send unlocking information of the passive lock corresponding to the position information to the key based on the position information, so that the key opens the passive lock.
9. A passive lock system, comprising: a passive lock, a key, and a cloud server, wherein,
the passive lock comprises a lock body, wherein a through lock hole is formed in the lock body; the first main control PCB is arranged in the lock body; the lock rods are respectively inserted into the lock holes; the locking piece is fixedly arranged in the lock body and is electrically connected with the first main control PCB, and the locking piece pushes against the locking rod inserted into the locking hole so as to lock the locking rod; the input module is arranged on the lock body and is electrically connected with the first main control PCB and the locking piece;
a key, a key body; the second main control PCB is arranged in the key body; the energy storage battery is arranged in the key body and is electrically connected with the second master control PCB; the output module is arranged on the key body and is electrically connected with the second main control PCB and the energy storage battery;
the cloud server is used for receiving the position information sent by the key and sending unlocking information of the passive lock corresponding to the position details to the key based on the position information so that the passive lock can be unlocked by the key.
10. A method of unlocking a passive lock system, the passive lock system being as recited in claim 9, the method comprising:
the key sends request information to a cloud server, wherein the request information comprises position information;
after receiving the request information of the key, the cloud server sends unlocking information of the passive lock corresponding to the position information to the key based on the position information;
after the key receives the unlocking information, the key is in adaptive connection with the passive lock so that the key supplies power to the passive lock and transmits the unlocking information to the passive lock;
and the passive lock checks the unlocking information with pre-stored verification information, and after the unlocking information is checked to be correct, the passive lock unlocks.
