Detailed ways

At present, the locks used in the substation cabinet are basically voice-activated locks and other locks. During the use of such locks, such as voice-activated locks, the locks are unlocked according to the pre-stored voice and the voice of the staff when needed, but this unlocking method cannot be guaranteed. The person who unlocks the lock is the staff member himself. For example, if the voice of the staff member is recorded and then played, the lock may be opened by someone who cannot unlock the lock. As a result, the lock is not safe enough, and the information cannot be monitored in real time, and remote control cannot be performed when necessary. Control or coordination, as shown in Figure 1, Figure 2 is an exploded view of a specific physical embodiment, and Figure 3 is an overall structural diagram of a specific embodiment of the real object, and this embodiment 1 is an electronic smart lock device applied to power cabinets, which features In, including:

When in use, install the device on the cabinet to be unlocked. During specific installation, it is necessary to set up corresponding mechanisms on the cabinet, such as corresponding shrinkage holes, fixing by screws, etc., which will not be described in detail here. When the staff needs to unlock , there are two unlocking methods in this embodiment. In the first method, the staff transmits information to the cloud server through a terminal device (such as a mobile phone or a pad, etc.), and the cloud server judges the information transmitted by the staff, such as account information and password information, Time information, etc., if it is a person who can unlock the lock, the unlock information will be passed to the communication module, the communication module will pass the information to the central controller, the central controller will control the motor and the drive module, and the motor drive module will control the opening of the motor lock. This method is adopted When the staff need to unlock the lock, they must first judge through the cloud server before unlocking, which ensures the safety of the lock;

Method 2 When unlocking, the staff transmits the information to the cloud server through the terminal device (such as mobile phone or pad, etc.), and the cloud server judges the information transmitted by the staff, such as account information, password information, time information, etc., if it is possible The person who unlocks the lock transmits the unlock information to the terminal device, the terminal device sends a message to the communication module, the communication module transmits the information to the central controller, the central controller controls the motor and the drive module, and the motor drive module controls the opening of the motor lock. When using the method, when the staff needs to unlock the lock, they must first judge through the cloud server before unlocking, which ensures the safety of the lock;

Realize keyless unlocking, bid farewell to the state of many, miscellaneous, chaotic keys, difficult management and search; reduce the time for relevant personnel to obtain keys on the way back and forth, can quickly locate the unlocking site, grasp the current status of the lock in time, and improve the safety of the power work site management level;

It should be noted that a reset switch can also be included, which communicates with the central controller. When the reset switch is set in the accommodation space, if the reset switch is pressed, it will send information to the central controller, and the central controller will control all related devices to the original state. Status, such as motor lock, communication module, etc. are restored to the original status.

It should be noted that the central controller can adopt a central processing unit, an exemplary low-power 32-bit microprocessor of STM32F103RCT6 can be used, and the motor lock can adopt a lock cylinder driven by a motor. When the signal is sent to the motor lock, the motor drives the motor lock to open the motor lock, and directly closes the box door or cabinet door that needs to be closed when it is closed. Specifically, the box door or cabinet door can be closed manually by the staff, and the lock cylinder will be closed due to the internal elastic force. Directly lock the cabinet door. This lock cylinder can be a common lock cylinder on the market, which is sold on Taobao, Jingdong and other online sites. The details will not be described here. The motor drive module is used to drive the motor, and the circuit corresponding to the motor lock is used. Yes, it can be used to drive the motor, control the speed and number of rotations of the motor, and be used in conjunction with the motor lock. This is the prior art and will not be described in detail here.
