Key storing and taking cabinet and key management system

Technical Field

The utility model relates to an equipment management field especially relates to a key access cabinet and key management system.

Background

The key is a common unlocking tool, different access doors such as an operation access door and an evacuation access door are arranged along a track, and all keys for opening the access doors can be stored in key storage equipment such as a key disc, a key box and a key cabinet by an operation and maintenance department door of track traffic. When an engineer executes an operation and maintenance task or emergency treatment, the key corresponding to the specified access door needs to be picked up from the key storage device, and the key is actively returned to the key storage device after the field operation is completed.

However, all keys at each stage of the station along the track are usually stored in one key storage device, the variety and the number of the keys are large, and the manager of the key storage device cannot track the state of the keys in real time and efficiently.

Referring to fig. 1, fig. 1 is a schematic view illustrating a first structure of a key access cabinet according to an embodiment of the present disclosure. Exemplarily, the key access cabinet comprises a cabinet body 100, an operation module 200 and a first number of key rings 300;

the cabinet body 100 comprises a storage area 110, an operation area 120 and a first number of key hooks 130, the key rings 300 are provided with electronic tags 310, each key ring 300 is fixed on the storage area 110 through one key hook 130, and the electronic tags 310 are used for identifying keys;

the operating module 200 includes a first controller 201, a transmission portion 202, a Radio Frequency Identification (RFID) reader 203 and a RFID antenna 204, where the first controller 201 and the RFID reader 203 are both disposed in the operating area 120, the first controller 201 is connected to the transmission portion 202 and the RFID reader 203, the RFID antenna 204 is connected to the RFID reader 203, the RFID antenna 204 is fixed to the transmission portion 202, the transmission portion 202 is disposed in the cabinet 100, and the transmission portion 202 is configured to drive the RFID antenna 204 to move.

The RFID reader 203 is used to read and write the stored information of the electronic tag 310 or locate the position of the electronic tag 310. The first controller 201 is implemented by an SoC (System on Chip), which is also called a System on Chip, and the processor, the internal operating memory, the external storage, and the like are integrated inside the SoC, so that the android System can be operated. In addition, the first controller 201 may also be implemented by a central processing unit, a microprocessor, a microcontroller, and the like, which is not limited herein. It should be understood that the number of the key ring 300 and the number of the key hooks 130 are both the first number, wherein the first number is set according to actual requirements, and is not limited herein. Optionally, the radio frequency protocol of the RFID reader 203 is EPC Class1 Gen2, ISO18000-6C protocol, and the operating frequency is 902MHZ to 928 MHZ.

The cabinet 100 is made of a carbon steel plate material, each key ring 300 is correspondingly fixed to the storage area 110 through one key hook 130, and keys to be stored are hung from the key hooks 130 through the key rings 300. When the user picks up the key, the corresponding key ring 300 is picked up. The first controller 201 quickly checks out the key received by the user according to the tag information read by the RFID reader 203.

After the first controller 201 sends a read-write command or a positioning command, the transmission portion 202 drives the RFID rf antenna 204 to move. According to the position of the electronic tag 310 to be read, the position of the RFID radio frequency antenna 204 is changed, and the radio frequency signal coverage of the RFID reader-writer 203 is expanded. Even if only one RFID rf antenna 204 is provided, the rf signal can still cover the entire cabinet 100, scanning all the electronic tags 310 in the storage area 110. By moving the RFID antenna 204, the coverage of the radio frequency signal is increased, and the identification accuracy of the RFID reader 203 is further improved, which is beneficial to the miniaturization and compactness of the key access cabinet.

According to the key access cabinet, the RFID reader-writer 203 reads the electronic tag information, the current state of the accessed key is tracked efficiently and accurately in real time, and the time consumed for taking the key and counting the key is reduced.

In this embodiment, the electronic tag 310 includes a sound tag 311, a light-emitting tag 312, and a radio frequency tag 313. Each electronic tag 310, which is affixed to the key ring 300 with the key, has a unique code. The radio frequency tag 313 is used for exchanging data with the RFID reader 203, transmitting an instruction sent by the RFID reader 203 to the second controller 320, and controlling the sound emitting tag 311 to emit sound and/or controlling the light emitting tag 312 to emit light through the second controller 320. Specifically, when the user receives a specific key, the key to be received is determined, and the position of the key to be received is determined according to the tag information read by the RFID reader-writer 203. The sound tag 311 corresponding to the key to be picked up emits sound and/or the light emitting tag 312 emits light, and the position of the key to be picked up is prompted to the user. When the user misses a key to a dark environment, the sounding label 311 emits a sound and/or the luminescent label 312 emits a light, so that the user can quickly determine the position of the key in the dark environment.
