Meanwhile, the control processing device manages each electronic key box, so that the electronic key box is safer and more intelligent.
Specifically, as shown in fig. 5, the central control operation panel controls and connects a liquid crystal display touch screen 121 with a touch function, a barcode scanner/two-dimensional code reader 122, an RFID card reader 123, a fingerprint recognition module 124, a face recognition module 125, a printer with a label printing function, and a sound box, and a label printing outlet 126 is arranged below the fingerprint recognition module 124. The label printer prints a label (figure 6) with a bar code/two-dimensional code by using a self-adhesive paper tape, and the label is stuck on a paper work ticket and the equipment isolation lock. The liquid crystal display touch screen 121 is used for man-machine interaction and content display, and the bar code scanner/two-dimensional code reader is used for reading a label of a bar code/two-dimensional code and can be installed alternatively. The two-dimensional code reader 122, the RFID card reader 123, the fingerprint identification module 124 and the face identification module 125 can be used for user identification and can be installed in a single or combined mode. The sound box is used for sending out prompt voice in a corresponding operation link and is an optional accessory.
As a preferable choice of the system for managing work ticket isolation keys provided in this embodiment, the system further includes a mobile APP client, where the mobile APP client is used for performing user identity information interaction with the central control operation panel, and is used for issuing a control command to the control processing device and implementing data exchange, instead of operating on the liquid crystal display touch screen, so as to implement remote management operation.
Specifically, the system operation and use method for managing the work ticket isolation key comprises the following steps:
【1】 Method for replacing mechanical lock key by using identity recognition
Anyone needs to identify before using the key cabinet, and can continue subsequent operations after success. The method comprises the following steps:
the user touches the lcd touch screen, activates the electronic key locker, and clicks the "start of use" module, as shown in fig. 7. The control processing device requires identity recognition. According to the setting of the production unit, the user carries out identity recognition in the following way:
(1) fingerprint identification: the user puts the registered finger on the fingerprint collector of the electronic key cabinet for identification
(2) Identifying the face: the user carries out face recognition towards the face recognition camera of the electronic key cabinet, and the production unit shown in fig. 8 can select the following mode to carry out dual identity recognition:
(3) the mobile phone two-dimension code: the user opens the cell-phone APP, shows the identification two-dimensional code to the two-dimensional code reader of electron key cabinet
(4) Digital password: user inputs 6 digit cipher in digital keyboard of LCD touch screen
(5) An RFID card reader: the user presses the work card close to the RFID card reader of the electronic key cabinet to read the work card information
The above operation is completed within 60 seconds, and the operation is automatically terminated if not.
【2】 Method for managing isolation key in process of using work ticket
1. After the work ticket issuing procedure is finished, the operator on duty runs to accept the key box.
The operator on duty uses the key cabinet, selects the module of 'registering work ticket', and the LCD touch screen prompts the input of work ticket number, work responsible person and work licensor. After the input is finished, the control processing device allocates a key box in an idle state to the control processing device, and the box door is automatically opened to prompt a user to check whether the key box is empty. After the user closes the cabinet door, the key box is designated as being dedicated to the work ticket until the last step is completed, which is only used for checking whether the opened key box is in an empty box state, and after the check, the operator on duty can close the key box at any time.
After this step, the key box is marked as "unlocked" at the control processing device.
2. After the key box is distributed, the operator on duty prints the isolation label to prepare for completing the isolation measure.
The operator on duty uses the key cabinet, selects the module of "printing the isolation label" in order to paste on paper work ticket and equipment isolation lock. After the user inputs the work ticket number, the electronic key cabinet prompts the user to print the number of the bar code/two-dimensional code labels, and after the user inputs the number, the key cabinet starts to print by using a label printer provided by the user.
3. And after the work licensor checks that the safety isolation measure is consistent with the work ticket and checks that the isolation key number is correct, the isolation key is put into the key box.
The work licensor uses the key cabinet to select the 'key box opening' module, and the liquid crystal display touch screen prompts scanning of the work ticket bar code/two-dimensional code. The user shows the bar code/two-dimensional code label on the paper work ticket to the key cabinet, the control processing device identifies whether the work ticket corresponds to the work licensor, and the key box used by the work ticket is automatically opened after the work ticket is determined to be correct. After the user puts in the isolation key, the key box is closed. After the box door is closed, the key box opening right transfer module on the liquid crystal display touch screen prompts a work licensor whether to transfer the key box opening right to a work responsible person. If yes, the key box is opened by the working responsible person. If the job licensor chooses "no," he can reopen the key box.
4. After the work licensor hands over the key box opening right, the work responsible person can open the key box if necessary before handling the work ticket license.
The work responsible person uses the key cabinet, selects "open key case" module, and the LCD touch-sensitive screen suggestion scans work ticket bar code/two-dimensional code. The user shows the bar code/two-dimensional code label on the paper work ticket to the key cabinet, the control processing device identifies whether the work ticket corresponds to the work responsible person or not, and the key box used by the work ticket is automatically opened after the work ticket is determined to be correct.
5. After the work ticket approval process is finished, the work licensor can lock the key box in 2 modes. After the key box is locked, the work responsible person and the work licensor cannot independently open the key box. After this step, the key box is marked as "locked" in the control processing means.
The first method is as follows: the work licensor uses the key cabinet to select the 'work permission' module, the liquid crystal display touch screen displays work tickets of the work licensor in the previous link, and after the work licensor selects the work tickets, the key cabinet locks the corresponding key box.
The second method comprises the following steps: the work licensor uses the mobile phone APP to select the 'work permission' module, the mobile phone displays work tickets in the last link under the name of the work licensor, and after the work licensor selects the work tickets, the corresponding key box is locked by the key cabinet.
6. After the work is finished, after the work responsible person confirms that all the workers evacuate from the work site, the locking of the key box by the person in charge is released, and one of the following modes can be selected for carrying out:
the first method is as follows: the work responsible person uses the key cabinet, selects the 'work finished' module, and the liquid crystal display touch screen displays the work ticket in the last link under the name of the work responsible person, and the work responsible person finishes the operation after determining that the work ticket is correct.
The second method comprises the following steps: the work responsible person uses the cell-phone APP, selects "the work is over" module, and the cell-phone shows the work ticket that is in the previous link under the work responsible person's name, and the operation is accomplished after the work responsible person confirms to be correct.
7. The work licensor checks that the site cleaning meets the relevant requirements, and after confirming that all the workers leave the work site, the work licensor releases the locking of the work licensor on the key box, and can select one of the following modes to carry out:
the first method is as follows: the work licensor uses the key cabinet to select the module for confirming the work completion, the liquid crystal display touch screen displays the work ticket in the last link under the name of the work licensor, and the work licensor completes the operation after determining that the work ticket is correct.
The second method comprises the following steps: the work licensor uses the mobile phone APP to select the 'confirm work end' module, the mobile phone displays the work ticket in the last link under the name of the work licensor, and the work licensor completes the operation after determining that the work ticket is correct.
After the link is finished, the control processing device releases the work ticket to lock the associated key box, checks whether the key box is still cross-locked by other work tickets or not, marks the key box as 'work end' if all the locks are released, and can carry out the next operation.
8. After the operator on duty checks that all the related maintenance work is finished, the control processing device can take the isolation key back from the key box after determining that the lock of the key box is released, and the security isolation measures are released item by item.
The operator on duty uses the key cabinet, selects the module of 'opening the key box', and the LCD touch screen prompts the scanning of the work ticket bar code/two-dimensional code. The user shows the bar code/two-dimensional code label on the paper work ticket to the key cabinet, and after the control processing device identifies the work ticket, the key box is automatically opened after the key box is determined to be in the 'work completion' state. After the user takes back the isolation key, the key box is closed, the box door is automatically locked, and the control processing device resets the key box to be in an idle state.
【3】 Management method for isolating keys when work ticket isolation measures are completely overlapped with other work tickets
If two or more work tickets need to implement safety isolation measures on the same group of equipment, the key boxes at the cross isolation points can be cross locked. If the isolation measures of the work ticket are all contained in other work tickets, the work ticket can not occupy the key box, and the security management of the isolation key is realized only by cross locking of the control processing device. For example, the isolation measures of the work ticket a are all included in the work ticket B, and at this time, the key box of the work ticket a may be selected as the key box corresponding to the work ticket B without occupying the key box.
1. After the work ticket signing procedure is finished, the operator on duty selects to cross lock the key boxes of other work tickets according to the safety measures in the work tickets.
The operator on duty uses the key cabinet to select the module of 'registering work ticket', the LCD touch screen prompts the input of work ticket number, work person in charge and work licensor, and selects 'need to cross lock other key boxes' (fig. 13). The key locker then prompts for the key box associated with the currently approved work ticket (fig. 14). After a user selects one or more key boxes, the control processing device adds cross locking to the key boxes to prompt whether a special key box needs to be applied for the work ticket or not, and the user selects 'not needed'.
2. And operating the operator on duty to print the isolation label and paste the isolation label on the work ticket.
The operation is the same as [ 2 ], and the number of the cross-locked key box is added with the mark of the mark at the end.
3. The working responsible person and the working licensor see that all the key boxes on the working ticket have the 'star' number, and know that the other working ticket key boxes are completely used and are in cross isolation.
