The recognition distance is adjustable and is 100 meters at most.

12. The top of the fixed plate 14 is provided with a video camera which is used for recording video and identifying information of a person using the key in the key taking/returning process.

13. The door suction switch 34 is used for giving a door opening signal to the PLC input module when the door is opened, the PLC controls the LED illuminating lamp 35 to be opened according to the signal change and gives a signal to the video unit, and the video unit starts to record the picture information of the door opening time period and identify the face information of people in the picture. When the door closing signal is given to the PLC input module by the door closing back door suction switch 34, the LED illuminating lamp 35 is turned off, and the video unit is turned off.

14. The camera video identifies personnel information and is linked with tool detection, and the key borrowing/lending record with the electronic tag is bound with the borrower information, so that tool management is facilitated, and people can be accurately reached.

15. The system records the entering and exiting of the key electronic tag and records the borrower information. And after the construction is finished every day, the system performs checking work, and the checking result is compared with the original record of the system to obtain the checking result. If a missing tool exists, the system prompts the missing information of the tool, wherein the missing information of the tool comprises the name, the serial number, the storage position, the delivery time, the borrower information, the video recording of the period of time for borrowing the materials and the historical delivery record of the modified materials which can be traced.

16. The key box door 7 is provided with a touch screen, when a worker opens the key box, the worker inputs a password on the touch screen, the information of the worker is recorded for the first time, and the password of each worker is different. After the password is input correctly, the touch screen displays the information of the key box, if all keys of the key box are in the box, the information of the missing keys is displayed. The missing key information includes the number, name, storage location, borrower, borrowing time, etc. of the key.

17. The key boxes can work independently or can work in a networking mode, a plurality of key boxes can be arranged on the vehicle, keys stored in each key box are different, a worker can inquire information of the keys to be used on the touch screen, and the keys to be used are stored in the first sockets of the key boxes at the positions.

18. The key box has a voice broadcasting function, can prompt a worker to borrow information of keys, and the voice report function can be switched on and off and edited on the touch screen and also can be edited on an upper computer.
