Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention, but do not limit the invention to only some, but not all embodiments.

The inventor has found that in recent years, with the development of sophistication and standardization of enterprise management, there is a demand for registration of keys for retrieval and return.

However, the inventor has found that the current key management is basically manually completed through long-term field research. The current key management methods mainly include two types:

the first method comprises the following steps: a conventional key box using a mechanical lock. The key box is provided with a general mechanical lock, and a special register book is prepared for registering taking and returning keys. This method is very low cost, but has many disadvantages, such as: the tedious registration work increases the workload of workers and reduces the work efficiency, or the people who use the key forget to register or make up afterwards, the significance of key management is suddenly lost.

The second method comprises the following steps: the key management box with the function of automatically detecting the key by using the diode can detect whether the key is borrowed or not, the management box can accurately manage each key, but still has the defects that related information cannot be automatically recorded or manual recording is needed, and the information of the key and the information of workers cannot be automatically configured and expanded by the workers. Such key management boxes are also costly and are typically used only as keys for managing superauthorities, such as master unlocking keys, keys in places with higher security levels, and the like.

In view of the above problems, the inventor has made extensive research and extensive experimental tests, and has ingeniously and creatively proposed the key management box of the present invention in combination with the requirements of the factory and mine enterprises on the spot, key management, security, and the like, so as to solve the above problems, and the scheme of the present invention is explained and illustrated in detail below.

The key management box of the invention comprises: controller, key deposit box, wherein, the controller includes: data module, login module, processing module, control module, identification module, alarm module and storage module, the key includes: a key tag configured with radio frequency identification technology; the flowchart of the method for taking the key from the key management box is shown in fig. 1, and specifically includes:

step 101: the data module receives key taking information sent by the management platform and sends the key taking information to the processing module, the key taking information is a number of a key needing to be taken and corresponding personnel information, and the personnel information is personnel information with the key authority of taking the corresponding number.

In the embodiment of the invention, the general key taking needs to be performed by a superior manager or a person with high-level authority, and the key taking information is sent through the management platform. The current factory and mine enterprises need to use a work ticket system in work, work tickets issued in the work ticket system are accompanied by numbers of keys needing to be taken and personnel information with the key authority of taking the numbers, the work tickets can be transmitted to a data module in a controller through a wireless communication device without limitation, the data module is processed to obtain the numbers of the keys needing to be taken and the personnel information with the key authority of taking the numbers, and the information is sent to a processing module.

The key in the embodiment of the invention comprises: key tags configured with Radio Frequency Identification (RFID) technology, such as: a chemical enterprise engages in a work on a certain day, and the serial numbers of keys required to be taken in the issued work ticket are as follows: 1#, the information of the person having the right to access the 1# key is: 690830, wherein 690830 is the employee number of the employee who is busy in a chemical industry enterprise, the number represents the unique id of the employee who is busy in the chemical industry enterprise, and the superior management personnel or the personnel with high-level authority of the chemical industry enterprise can set various authorities of the employee in a certain way.

After a superior management person or a person with high-level authority issues a 001# (serial number of a work ticket) work ticket, the 001# work ticket is issued to a data module of the key management box, and after the data module receives the work ticket, the data module processes the work ticket to obtain the serial number of a key to be taken: 1#, the person with the right to access the 1# key: 690830. and the data module sends the information to the processing module.

Step 102: the login module receives login information and sends the login information to the processing module, wherein the login information comprises but is not limited to personnel information with the key authority of the corresponding number;

in the embodiment of the invention, after the work ticket is sent to the data module, related workers need to go to the site where the key management box is located, login is firstly carried out, and after the login is successful, the login module receives login information and sends the login information to the processing module. Of course, the login information includes, but is not limited to, personnel information having the right to access the key corresponding to the number. It should be noted that, when a general worker logs in, the login can be completed in the form of an account password or in the form of scanning a fingerprint.

In a general account password form, an account refers to the employee number of a worker, and a password is a password set by the worker; in the form of scanning the fingerprint, the fingerprint information of the relevant staff needs to be recorded into the login module in advance, and it can be understood that the fingerprint information is also uniquely corresponding.

For example: the staff inputs the staff number of self on the key management box in the sky: 690830 and a password 654321, or directly using a fingerprint scanning mode to log in, the login module will receive login information: 690830 log in and send the information to the processing module.

Step 103: the processing module receives the key information and the login information and judges whether the personnel information in the key information is matched with the personnel information in the login information according to the key information and the login information;

in the embodiment of the invention, the processing module receives the key-taking information from the data module and the login information from the login module, and judges whether the personnel information in the key-taking information is matched with the personnel information in the login information according to the key-taking information and the login information, the numbers of all keys in the key storage box stored by the processing module per se and the personnel information with the authority of taking the keys in the key storage box. The reason why the stored serial numbers of all the keys in the key storage box and the stored information of the persons who have the authority to access the keys in the key storage box are needed is that the persons who issue the work tickets may access the keys with the serial numbers in the issued work tickets due to various reasons.

The above-mentioned method also improves the safety to some extent, because the factory and mining enterprises generally include a large number of devices, apparatuses, etc., and the general staff can only master the operation and operation of the devices, apparatuses, etc. in charge of the staff, such as: if the first employee takes the key related to the equipment, the device and the like in the second area, the first employee may be injured because the first employee does not take the key related to the equipment, the device and the like in the second area, or the equipment and the device in the second area may be mistakenly operated to cause the equipment and the device in the second area to be failed, the operation is stopped and the like, so that the first employee is required to limit the personnel with corresponding capability and who take the related operation to take the key in the corresponding area.

It should be noted that before the key management box is used for the first time, the serial numbers of all the keys in the key storage box and the personnel information having the authority to access the keys in the key storage box need to be entered into the processing module of the key management box, and certainly, in the later use process, no matter the serial numbers of the keys are changed or the personnel information is changed, the relevant information stored in the change processing module can be updated according to the actual situation. For example: in the later use process, some new keys may be added in the key storage box, and the new keys are determined to have the numbers of the new keys, so that the numbers of the new keys need to be stored in the processing module, and by the same reason, if some keys do not need to be managed by using the key management box, the numbers corresponding to the keys need to be removed, or the numbers of some keys are changed to 6# before and are changed to 8# now, and the numbers need to be updated and changed in the processing module. The same principle is applied to the change and update of the personnel information.

For example: when the key management box is put into use at the beginning, only 10 keys are provided, and then the 10 keys are respectively numbered: 1# to 10#, there are two workers: 690830 and 690860 have the right to access the 10 keys, the information is entered into the processing module. After using for a period of time, increased 8 keys again, numbered respectively: 11# to 18#, adding one worker: 690140 has the authority to access 11# -18 # keys, but 690140 does not have the authority to access 1# -10 # keys, whereas the authority to access 690830 is changed to have the authority to access 1# -12 # keys and the authority to access 690860 is changed to have the authority to access 1# -8 # keys, the corresponding information stored in the processing module needs to be updated.

In the using process, the processing module receives the number of the key needing to be taken, which is sent by the data module: 1#, the person with the right to access the 1# key: 690830, and login information sent by the login module: 690830 log in, and the processing module has stored information on the 1# key in the key storage box and the person having the right to access the 1# key: 690830, to determine whether the person information in the key retrieval information matches the person information in the registration information. If the serial number of the key needing to be taken in the issued work ticket: 1#, the person with the right to access the 1# key: 690830, the received login information is: 690830, the processing module has stored the staff member 690830 with the authority to access the 1# key, then it is determined that the staff information in the key access information matches the staff information in the login information.

If the personnel making a work order have a mistake, the serial number of the key needing to be taken in the made work order is as follows: 1#, the person with the right to access the 1# key: 690140, but the processing module has stored the staff member 690140 without access to the 1# key, then it is determined that the staff information in the key access information does not match the staff information in the login information.

If the personnel making a work order have a mistake, the serial number of the key needing to be taken in the made work order is as follows: 1#, the person with the right to access the 1# key: 690830, but the login information received is: 690860, even if the processing module has stored the staff member 690860 with the authority to access the 1# key, the staff member information in the key access information is determined not to match the staff member information in the login information.

Step 104: under the condition that the personnel information in the key-taking information is matched with the personnel information in the login information, the processing module sends a door opening instruction to the control module;

step 105: the control module receives a door opening instruction and opens a door of the key storage box body, so that a key needing to be taken is taken;

in the embodiment of the invention, the processing module sends a door opening instruction to the control module under the condition that the personnel information in the key taking information is matched with the personnel information in the login information, and the control module can open the door of the key storage box body after receiving the door opening instruction, so that a worker can take the key to be taken.

It should be noted that the key storage case includes: electromagnetic lock and reserve mechanical lock, under the general condition, can open the chamber door that the box was deposited to the key by control module control electromagnetic lock, nevertheless if the electromagnetic lock damages, when can not normally open, can also open the chamber door that the box was deposited to the key through reserve mechanical lock for the staff takes the key that needs were taken.

In addition, the key management box also comprises a timing module, when the control module opens the box door of the key storage box body, the timing module starts to time and sends a closing instruction to the control module after preset time, so that the control module controls the electromagnetic lock to close the box door. The reason for doing so is that the situation that a worker forgets to close the door of the key storage box after taking the key may occur, if the door is not closed, the situation that the key is lost or is taken away randomly by any other person may occur, which is not allowed, so that a timing module and preset time are set, and if the worker closes the door of the key storage box after taking the key, the timing module automatically stops working and does not continue timing; if the door of the key storage box body is not closed after the key is taken by the worker, the timing module starts to time and sends a closing instruction to the control module after the preset time, so that the door of the key storage box body is automatically closed.

For example: the processing module receives the number of the key needing to be taken and sent by the data module: 1#, the person with the right to access the 1# key: 690830, and login information sent by the login module: 690830 log in, and the processing module has stored information on the 1# key in the key storage box and the person having the right to access the 1# key: 690830, judging whether the personnel information in the key fetching information is matched with the personnel information in the login information, sending a door opening instruction to the control module by the processing module, and controlling the electromagnetic lock to be opened after the control module receives the door opening instruction, so that the staff 690830 can fetch the 1# key.

Optionally, in the above process, if the processing module determines that the person information in the key information does not match the person information in the login information, the processing module may directly send an alarm instruction to the alarm module, so that the alarm module sends an alarm. It should be noted that the key management box further includes: stereo set loudspeaker, alarm module send the warning and can send alarm sound through stereo set loudspeaker, and simultaneously, alarm module sends alarm information and gives management platform, lets higher level's managers or the personnel that have high-grade authority know, has carried out subsequent processing, and this is favorable to having improved the security that the key used equally.

Step 106: the identification module receives the serial number of the taken key through a radio frequency identification technology and identifies whether the serial number of the taken key is consistent with the serial number of the key needing to be taken in the key taking information;

in the embodiment of the invention, after the worker takes the key to be taken, the identification module is required to identify again whether the number of the taken key is consistent with the number of the key to be taken in the key taking information. This is because, when the key storage box is opened, a large number of keys are arranged inside the key storage box, and although each key is provided with a label or an identifier to indicate the number of each key, a worker who takes the key may take the wrong key, so after taking the key, the identification module receives the number of the taken key again through the radio frequency identification technology, and identifies whether the number of the taken key is consistent with the number of the key which needs to be taken in the key taking information, so as to ensure that the taken key is correct.

For example: after the worker 690830 takes the 1# key, the worker swipes the key plate of the 1# key through the card swiping area, and the identification module can receive and identify the serial number of the taken key to be 1# through the RFID technology. The corresponding parts of the card swiping area are explained and illustrated below, and are not described herein again.

Step 107: under the condition that the number of the used key is inconsistent with the number of the key needing to be used in the key taking information, the identification module sends an alarm instruction to the alarm module, so that the alarm module gives an alarm;

in the embodiment of the invention, when the identification module identifies that the number of the taken key is not consistent with the number of the key needing to be taken in the key taking information, an alarm instruction is also sent to the alarm module, so that the alarm module gives an alarm to enable relevant personnel to process the alarm.

Step 108: when the number of the taken key is consistent with the number of the key needing to be taken in the key taking information, the identification module sends a storage instruction to the storage module, so that the storage module stores the number of the taken key and the personnel information of the taken key.

In the embodiment of the invention, when the identification module identifies that the number of the taken key is consistent with the number of the key needing to be taken in the key taking information, a storage instruction is sent to the storage module, and after the storage module receives the storage instruction, the number of the taken key and the personnel information of the taken key are stored.

For example: after the staff 690830 took the 1# key, through the key board of the 1# key of the district of punching the card, the identification module received and discerned the serial number of the key of being taken through RFID technique and is 1#, will be to storage module storage instruction, and storage module receives behind the storage instruction, can save the serial number of the key of being taken: 1#, and person information for key access: 690830, and automatically adds time, i.e., the information stored by the storage module would be: 2019.8.18.11:00+1# Key +690830+ access.

Optionally, in the embodiment of the present invention, the key may be divided into a general authority key and a special authority key according to an actual characteristic of the key, the special authority key may be used only after being approved by a superior administrator, and authority information of the general authority key and the special authority key is stored in the processing module. The key management box further comprises: and a request module. When the processing module judges that the personnel information in the key fetching information is matched with the personnel information in the login information and the key fetching information needs to be the key with the common authority, the processing module directly sends a door opening instruction to the control module so that a door of the key storage box body is opened; when the processing module determines that the personnel information in the key fetching information is matched with the personnel information in the login information and the key needing to be fetched in the key fetching information is a special authority key, the processing module needs to send a special authorization request instruction to the request module, wherein the special authorization request instruction is an instruction for requesting an upper-level manager to use the special authority key; after receiving the request special authorization instruction, the request module sends a request to the superior manager, and after receiving the request, the superior manager performs corresponding operation according to the actual situation.

Optionally, in the embodiment of the present invention, the key management box further includes a detection module, and after a key to be taken is taken, the detection module detects whether a geographic position of the taken key exceeds a preset range; when the geographical position of the taken key exceeds the preset range, the detection module sends an alarm instruction to the alarm module, so that the alarm module gives an alarm.

For example: after the worker 690830 takes the 1# key, the worker wants to configure a same key maliciously to achieve the purpose of some undeniable persons, and will take the 1# key to configure the key, and then certainly will exceed the range of the industrial and mining enterprises, and when the detection module detects that the geographic position of the 1# key exceeds the range (i.e. the preset range) of the industrial and mining enterprises, the detection module sends an alarm instruction to the alarm module, so that the alarm module gives an alarm, and relevant persons perform subsequent processing.

Optionally, after the related work is finished, the used key needs to be returned, and the login information further includes: referring to fig. 2, a flow chart of a method of returning a key is shown:

step 201: the login module receives the personnel information of the returned key and sends the personnel information to the processing module;

in the embodiment of the invention, when returning the key, the operator logs in firstly, and general factory and mining enterprises require the principle of who takes and returns for safety and normative considerations, namely, the key taken by the operator A needs to be returned by the operator A except special conditions, and when returning the key taken by the operator A, the login module receives the personnel information of the returned key and sends the personnel information to the processing module.

For example: the staff 690830 has taken the 1# key, and after the work was finished, it needed to return the 1# key, and it first logs in on the key management box, and the login module received the personnel information of returning the key: 690830, and to the processing module.

Step 202: the data module receives a key returning request and sends the key returning request to the processing module, the key returning request is a request for returning the taken key, and the key returning request comprises: returning the number of the key taken;

in the embodiment of the invention, after the staff logs in, the option of returning the key can be selected. It should be noted that in practical applications, there may be a case that: when the worker 690830 initially takes the 1# key, and then the work ticket is added with work content, and the worker 690830 needs to continue to take the 2# key, after the worker 690830 logs in, two options are presented, namely a return key and a take key, because the 1# key needs to be continuously used but cannot be returned at this time, the worker 690830 needs to select the option of taking the key, if the 1# key can be returned at this time, but the 2# key needs to be taken, the worker 690830 can select the option of taking the key first, complete taking the 2# key according to the method of steps 101 to 108, and then select the option of returning the key, and of course, can select the option of returning the key first, and then select the option of taking the key.

After the operator selects the option to return the keys, it is also necessary to determine the number of the keys to be returned, since the operator may have accessed more than one key, but only one or a few of the keys, rather than all, need be returned, and thus the number of the keys to be returned. After the determination, the data module receives a key returning request and sends the key returning request to the processing module, the key returning request is a request for returning the taken key, and the key returning request comprises: the number of the key taken is returned.

For example: the operator 690830 has accessed the 1# key, and at this time the 1# key needs to be returned, then after selecting the return key option, the number of the key to be returned is determined: 1#, the data module receives a rekey request: and the 1# key is sent to the processing module.

Step 203: the processing module receives the personnel information of the returned key and the key returning request, calls the number of the taken key and the personnel information of the taken key stored in the storage module, and judges whether the personnel information of the returned key and the number of the returned taken key in the key returning request are matched with the number of the taken key and the personnel information of the taken key stored in the storage module;

in the embodiment of the invention, the processing module receives the personnel information of the returned key and the key returning request, calls the stored serial number of the taken key and the personnel information of the taken key, and judges whether the personnel information of the returned key and the serial number of the returned taken key in the key returning request are matched with the serial number of the taken key and the personnel information of the taken key stored in the storage module. Since the taken key certainly has a corresponding record, when the key is returned, the judgment can be carried out only by calling the stored serial number of the taken key and the personnel information of the taken key.

Step 204: the identification module receives the number of the key to be returned and taken through the radio frequency identification technology and identifies whether the number of the key to be returned and taken is consistent with the number of the key to be returned and taken in the key returning request;

in the embodiment of the invention, in the process of returning the key, the identification module receives the number of the key to be returned and taken through the radio frequency identification technology and identifies whether the number of the key to be returned and taken is consistent with the number of the key to be returned and taken in the key returning request, so that the reason for this is to ensure the correctness of the key to be returned and avoid that a worker returning the key takes the key with return by mistake or inputs the wrong number of the key to be returned.

Step 205: under the condition that the personnel information of the returning key information and the serial number of the returned and taken key in the key returning request are matched with the serial number of the taken key and the personnel information of the taken key stored in the storage module, and the serial number of the key to be returned and taken is consistent with the serial number of the returned and taken key in the key returning request, the processing module sends a door opening instruction to the control module and sends a returned instruction to the storage module;

step 206: the control module receives a door opening instruction, and opens a door of the key storage box body, so that the key to be returned and taken is returned;

step 207: the storage module receives the returned instruction, and stores the number of the returned key and the personnel information of the returned key;

in the embodiment of the invention, the processing module sends a door opening instruction to the control module and sends a returned instruction to the storage module when judging that the personnel information of the returned key information and the serial number of the returned and taken key in the key returning request are matched with the serial number of the taken key and the personnel information of the taken key stored in the storage module and the serial number of the key to be returned and taken is consistent with the serial number of the returned and taken key in the key returning request. The control module receives the door opening instruction and controls the electromagnetic lock to open the door of the key storage box body, so that the key to be returned and taken is returned. And the storage module receives the returned instruction and stores the number of the returned key and the personnel information of the returned key.

Of course, it can be understood that, as in the case of taking the key, in the process of returning the key, if the door of the key storage box body is closed after the operator returns the key, the timing module automatically stops working and does not continue timing; if the door of the key storage box body is not closed after the key is returned by the staff, the timing module starts to time and sends a closing instruction to the control module after the preset time, so that the door of the key storage box body is automatically closed.

For example: the operator 690830 has accessed the 1# key, and at this time the 1# key needs to be returned, then after selecting the return key option, the number of the key to be returned is determined: 1#, the data module receives a rekey request: 1# key, which is sent to the processing module, the processing module judges the personnel information 690830 of the returning key information and the number of the returned and taken key in the returning key request, 1#, and the number of the taken key stored in the storage module: 1# and person information with key: 690830, and the staff 690830 swipes the key tag of the 1# key through the card swiping area, the identification module receives and identifies the number 1# of the taken key through the RFID technology, the processing module sends a door opening instruction to the control module, and sends a returned instruction to the storage module. The control module receives the door opening instruction and controls the electromagnetic lock to open the door of the key storage box body, so that the 1# key is returned. The storage module receives the returned instruction, and stores the number of the returned key: 1# and person information of return key: 690830, and automatically adds time, i.e., the information stored by the storage module would be: 2019.8.18.18:00+1# Key +690830+ Return.

Step 208: and under the condition that the personnel information of the returned key information and the serial number of the returned and taken key in the key returning request are not matched with the serial number of the taken key and the personnel information of the taken key stored in the storage module, or the serial number of the key to be returned and taken is not consistent with the serial number of the returned and taken key in the key returning request, the processing module sends an alarm instruction to the alarm module, so that the alarm module gives an alarm.

In the embodiment of the invention, as in the case of taking the key, under the condition that the personnel information of the returned key information and the serial number of the returned taken key in the key returning request are not matched with the serial number of the taken key and the personnel information of the taken key stored in the storage module, or the serial number of the key to be returned and taken is not matched with the serial number of the returned taken key in the key returning request, the processing module sends an alarm instruction to the alarm module, so that the alarm module gives an alarm.
