In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention will now be further described with reference to the accompanying drawings.

Referring to fig. 1 to 3, an electronic lock includes a bottom plate 1, an electromagnetic lock 2, two steering engines 3 and a pair of door panels 4, where the bottom plate 1 is provided with a through hole 5, the electromagnetic lock 2 includes an electromagnet 201 and a lock body 202, the two steering engines 3 are both installed on the bottom plate 1, the two steering engines 3 are respectively connected to one door panel 4 through a rotating shaft to control an opening and closing angle of the door panel 4, one electromagnet 201 or one lock body 202 in the electromagnetic lock 2 is installed on the door panel 4, the corresponding lock body 202 or one electromagnet 201 is installed on the bottom plate 1, the door panel 4 is provided with a semi-through hole 6, and a pair of door panels forms a full-through hole matching with the through hole 5 after being closed. A buffer layer 7 is arranged in the semi-through hole. The buffer layer 7 is a sponge layer. The number of the electromagnets 201 is 4, and every two electromagnets are symmetrically arranged on one door panel 4 in a group. The steering engine 3 is a large-torque steering engine.

When the embodiment of the invention is implemented specifically, the pair of door panels 4 are symmetrically distributed on the left side and the right side of the 8L container and fixed on the deep cooling box or the birdcage rack, and the two parts of the electromagnetic lock 2 are respectively arranged on the side edges of the pair of door panels 4. When the pair of door plates 4 are closed, the electromagnetic lock can be automatically locked, and at the moment, the circular area (through hole 5) in the middle of the bottom plate 1 is tightly attached to the container and fixes the container on a deep-cooling box or a birdcage frame. When the electromagnetic lock 2 is in an open state, the door plate 4 can be respectively controlled by two steering engines to open and close the door, and the opening and closing angle of the door plate can be adjusted within a certain range.

In one embodiment, the electronic lock further comprises an alarm module. The alarm module is an audible alarm or an optical alarm or an audible and visual alarm. The alarm module is arranged to facilitate control of the electronic lock. Specifically, because the electronic lock includes a plurality of electromagnetic locks, the alarm module alerts when there is one or more of the electromagnetic locks that need to be unlocked but are not unlocked. And on the contrary, when one or more electromagnetic locks need to be locked but are not locked, the alarm module gives an alarm for prompting.

Based on the electronic lock, please continue to refer to fig. 3, which shows an electronic lock control method, the invention adopts a PLC or embedded single chip microcomputer form to make an electronic lock controller. After initialization, all locks are ensured to be in a closed state, all locks are numbered in the controller, and the controller of the electronic lock can be combined with the controller of the forking robot, the state of the cryogenic box (whether a container exists) and the state of the birdcage (whether a container exists) to form integrated background control in actual use. According to this according to the container condition judgement in cryogenic box and the birdcage and open the lock of a certain number and send out the signal of unblanking, the system can indicate whether have other locks to be in the open mode and send out the suggestion of reporting to the police before unblanking, if not then can directly unblock the lock of specific number, the steering wheel then drives the electronic door and opens the angle of setting for, and fork and get the robot and also can confirm the position that needs transport or place the container according to the serial number of unblanking, after transport or place the container and finish, this department's electronic lock will automatic closure. The process is repeated in such a way to realize the opening and closing and interlocking of the electronic lock.
