Further, the intelligent unlocking key management box includes an electronic door lock, and the door lock state detection unit includes a micro switch arranged in the electronic door lock. When the electronic door lock of the management box is opened or closed, the micro switch can The processor unit sends a binary signal.

Further, the key presence detection unit includes a gravity switch and a hook connected under the gravity switch; when the unlock key is hung on the hook, the switch signal of the gravity switch is sent to the processor unit.

Further, the display screen adopts a touch screen capable of inputting information.

The advantages of the present invention are:

1) Eight unlocking keys can be managed at the same time, and the name and status of each key are directly displayed on the display screen, which is convenient for the operation and maintenance personnel to check at a glance when the station is under normal conditions, reducing the workload of the operation and maintenance personnel and saving time.

2) The system administrator needs to swipe the card and enter the password to open the unlock key management box; the general operator needs to swipe the card, and after obtaining the authorization and approval of the authorized person, enter the verification code after passing the SMS verification to open the unlock key management box; every time the door is opened and Door closing records are automatically generated and saved, and reported to the system management host; when the unlock key is used or returned, the key usage records are also reported to the system management host, so that the recorded data will not be lost and the archives can be checked.

3) The system host is independent of the external network and the internal network, and the network port is closed; the system communication adopts SMS short message communication; the system communication has strict mobile phone number judgment, and invalid information is uniform.

detailed description

The present invention will be further described below in conjunction with specific drawings and embodiments.

The unlocking key management information system provided by the present invention includes a system management terminal and a monitoring site terminal;

The system management terminal includes the system management host and the dual-channel SMS modem connected to the system management host, as well as the authorized person's mobile phone; one of the dual-channel SMS modems is responsible for data communication with the on-site intelligent unlock key management box, and the other is responsible for receiving the authorized person and verification code people to conduct SMS text communication;

The monitoring site includes a smart unlock key management box and a verification code receiving mobile phone;

The intelligent unlocking key management box comprises a door lock state detection unit, a key in-position state detection unit, a processor unit, a storage unit, a power supply unit, a card reader unit, a display screen and a short message data transmission module of the management box; the door lock state detection The unit and the key in-position state detection unit are respectively connected to the input end of the processor unit; the processor unit is connected to the storage unit, the card reading unit, the display screen and the SMS data transmission module respectively; the power supply unit is used for power supply in the management box; the display screen Using a touch screen that can input information;

The intelligent unlocking key management box includes an electronic door lock, and the door lock state detection unit includes a micro switch arranged in the electronic door lock. When the electronic door lock of the management box is opened or closed, the micro switch can send a signal to the processor unit Send a switch signal; the door opening information can be stored through the storage unit and can be further reported to the system management host through SMS;

As shown in Figure 2, the key presence detection unit comprises a gravity switch 201, a hook 202 connected below the gravity switch 201; the gravity switch 201 is installed on the inner top wall or side wall of the key management box; When the 202 is on, the gravity switch 201 turns from closed to open due to the weight of the key (or from open to closed, depending on whether the gravity switch is initially normally closed or normally open), and the switch signal of the gravity switch 201 is sent to the processing The processor unit can monitor whether the unlocking key 203 is in place; the intelligent unlocking key management box of the present invention is configured with eight groups of gravity switches 201 and hooks 202, and can manage eight unlocking keys simultaneously. The name and status of each key are directly displayed on the display screen, which is convenient for the operation and maintenance personnel to visit the station in a normal state at a glance, reducing the workload of the operation and maintenance personnel and saving time.

The card reading unit is used to read the cardholder's card swiping information.

When the smart unlock key management box is put into operation, the corresponding authorized person and verification code recipient information are configured.

When the on-site operator swipes the card with the card and selects the authorized person and the recipient of the verification code, the unlocked key management box sends the cardholder's card number information, the selected authorized person and the recipient of the verification code to the system management host through a text message, and the system After receiving the information, the management host judges the legitimacy of the cardholder through the cardholder's card number information, and applies for authorization to the authorizer through the SMS text channel. After the authorized person's authorization and approval, the random verification code is automatically generated and sent to the unlock key management box and the verification code receiver's mobile phone through the data SMS channel and the text SMS channel respectively. The cardholder can only open it by entering the correct verification code. Unlocks the Key Management Box. The new verification code can be input through the touch screen; after the unlock key management box is opened, it will automatically record the door opening information (time, authorizer, cardholder, etc.) and actively report it to the system management host. When returning, the unlocked key management box also automatically records the key usage (time, use or return) according to the switch signal of the gravity switch and actively reports to the system management host through the SMS channel, and the system host automatically sends the key usage record to the authorized person .

This unlocking key management information system can also set up a system administrator. After the system administrator swipes the card and enters the password to unlock the key management box, the door will automatically open, while the general operator needs to swipe the card as mentioned above, pass the SMS verification, and then enter the verification code to unlock the key management. box to open the door.
