一种基于指纹识别系统的钥匙管理箱A key management box based on fingerprint recognition system

技术领域technical field

本实用新型涉及一种钥匙管理装置，特别是涉及一种基于指纹识别系统的钥匙管理箱。The utility model relates to a key management device, in particular to a key management box based on a fingerprint identification system.

背景技术Background technique

传统的钥匙管理方式比较落后，还是以“人管”为主，将大量钥匙集中串起来归一人保管，或把钥匙放到一般箱子里锁起来，而开箱的钥匙就存放在个别人手上。倘若保管钥匙的人不在，那么可能导致所有人都无法取到钥匙。并且借还钥匙的管理主要还是采用纸面记录的方式，不仅增加了运行人员和运行成本，而且存在漏记或记错的现象。The traditional key management method is relatively backward, and it is still dominated by "personal management". A large number of keys are collected and kept by one person for safekeeping, or the keys are put in a general box and locked, and the key to open the box is stored in the hands of an individual. If the person keeping the key is not there, it may result in no one being able to get the key. Moreover, the management of borrowing and returning keys mainly adopts paper records, which not only increases operating personnel and operating costs, but also has the phenomenon of omission or misremembering.

本实用新型的工作流程图如图3所示，本实用新型由箱体、可编程控制器、指纹识别器、液晶显示器及储存器组成。控制器采用Cortex M3为处理器，主要利用LCD液晶触摸屏进行人机互动，能够实时显示各把钥匙目前状况，通过触摸相应的虚拟按键能查看某把钥匙被谁在使用，使用时间等信息。控制器经过串口与指纹识别器通信来识别用户身份，进行相关处理后，启动电机对箱子解锁。解锁后，用户可以同时进行钥匙的取走或还回操作，无需分开两次解锁来实现。在取还钥匙后，主控制器会将记录相关钥匙的取还时间和使用者等信息，并且存储于专门的储存器中，防止断电后数据的掉失。而且，每根钥匙都配有唯一的钥匙套，令钥匙的拿取迅速、正确，避免了钥匙的乱摆放。另外，用户指纹的添加和删除无需额外通过电脑来操作，只需要在本实用新型通过被授权的用户指纹来获取高级权限便可实现，这样有利于管理层随时更新用户列表。在安全性方面，能在钥匙箱被外部因素强制打开的情况下，发出警告声来引起相关人员的注意。The working flow chart of the present utility model is as shown in Figure 3, and the utility model is made up of casing, programmable controller, fingerprint reader, liquid crystal display and storage device. The controller uses Cortex M3 as the processor, and mainly uses the LCD touch screen for human-computer interaction, which can display the current status of each key in real time. By touching the corresponding virtual button, you can check who is using a certain key, the usage time and other information. The controller communicates with the fingerprint reader through the serial port to identify the user's identity, and after related processing, it starts the motor to unlock the box. After unlocking, the user can take away or return the key at the same time, without needing to unlock twice. After the key is retrieved, the main controller will record the relevant key retrieval time and user information, and store it in a special memory to prevent data loss after power failure. Moreover, each key is equipped with a unique key cover, so that the key can be taken quickly and correctly, and the random placement of the key is avoided. In addition, the addition and deletion of user fingerprints do not need to be operated additionally through a computer, and only need to obtain high-level permissions through authorized user fingerprints in the utility model, which is beneficial for the management to update the user list at any time. In terms of safety, when the key box is forced to open by external factors, a warning sound can be issued to attract the attention of relevant personnel.

存储器与控制器之间为双向通信，控制器将钥匙信息存储进存储器，同时能读取存储器内的钥匙信息；控制器与液晶触摸屏之间为双向连接，控制器更新液晶触摸屏的显示情况，使显示处于最新状态，而液晶显示屏向控制器反馈用户在触摸屏界面的操作情况。用户对触摸屏的操作分为三种，进入取还钥匙功能、查询钥匙功能或配置功能。There is two-way communication between the memory and the controller, the controller stores the key information into the memory, and can read the key information in the memory at the same time; the controller and the LCD touch screen are two-way connected, the controller updates the display of the LCD touch screen, so that The display is up-to-date, while the LCD displays feedback to the controller about what the user is doing on the touch-screen interface. There are three types of user operations on the touch screen, entering the key retrieval function, key query function or configuration function.

当用户进入取还钥匙功能界面，通过指纹识别判断该用户是否存在，用户不存在则返回液晶触摸屏主界面，用户存在则解锁开门，在用户取还钥匙完毕且合上门后将信息反馈给控制器，由控制器更新液晶触摸屏显示钥匙状况。When the user enters the function interface of retrieving and returning the key, judge whether the user exists through fingerprint recognition. If the user does not exist, it will return to the main interface of the LCD touch screen. , the controller updates the LCD touch screen to display the key status.

当用户进入查询钥匙功能界面时，能够查询到当前某条钥匙的使用状态，在箱内或有人取出未还，谁取出等信息，使用户能及时了解钥匙动态。When the user enters the query key function interface, he can query the current use status of a certain key, such information as whether someone took it out of the box or who took it out, so that the user can keep abreast of the key dynamics.

当用户进入配置功能经过指纹识别判断是否为授权的用户，未授权用户则返回到液晶触摸屏主界面，被授权用户则进行增加用户或删除用户或设置时间操作，并将操作结果存储在存储器中，并通过存储器反馈给控制器，最后在液晶触摸屏显示更新情况。When the user enters the configuration function and judges whether he is an authorized user through fingerprint identification, the unauthorized user returns to the main interface of the LCD touch screen, and the authorized user performs operations such as adding users or deleting users or setting time, and the operation results are stored in the memory. And feed back to the controller through the memory, and finally display the update status on the LCD touch screen.

当锁门出现异常情况时，控制器通过报警系统发出警告声来引起相关人员的注意。控制器能发出锁钥匙管理箱的门等命令。When there is an abnormal situation in the locked door, the controller sends out a warning sound through the alarm system to attract the attention of relevant personnel. The controller can issue commands such as locking the door of the key management box.

上述实施例中提到的内容并非是对本实用新型的限定，在不脱离本实用新型的实用新型构思的前提下，且任何显而易见的替换均在本实用新型的保护范围之内。The contents mentioned in the above embodiments are not limitations of the present utility model, and any obvious replacements are within the protection scope of the present utility model without departing from the utility model concept of the present utility model.
