  Electronic locks, implemented by electromagnets (or micro-motors) and lock bodies, combine electronic technology and integrated circuit design components with a variety of innovative identification technologies (including computer network technology, built-in software cards, network alarms, lock body mechanical design). ) and other comprehensive products. It is different from the traditional mechanical lock, does not need to use a metal key, is convenient to use, and has a strong confidentiality.

  The basic structure of the

  electronic lock is now more electronic locks with 51 series single-chip microcomputer (AT89051) as the center, with the corresponding hardware circuit, complete the setting, storage, identification and display of the code, drive the electromagnetic actuator and detect its drive current value, Accept the alarm signal sent by the sensor, send data and other functions.

  The one-chip computer accepts the typed code and compares it with the code stored in the EEPROM. If the code is correct, the electromagnetic actuator is unlocked; if the code is incorrect, the operator is allowed to input the code from the beginning, and can input up to three times; if it is three times If it is not correct, the MCU will alarm the intelligent monitor via the communication line. The single-chip microcomputer sends each time the unlocking operation and the driving current value of the electromagnetic actuator to the intelligent monitor as the status information, and sends the alarm information from the sensor interface to the intelligent monitor as a basis for intelligent profiling.

  Wireless electronic locks. Non-door lock electronic locks can be used for transportation, warehousing, milk delivery vehicles, cash trucks, refrigerated trucks, drug delivery, tobacco transportation, etc. For example, it is used in the door of the cash transport truck, the manhole cover of the special vehicle and the door of the warehouse to ensure the safety of the goods transported or guarded and to avoid theft. The electronic lock uses a mechanical lock body to contact the related skills of the Internet of Things, and the lock body has a built-in wireless transceiver module. When the lock body is turned on and off, the wireless transceiver module transmits the open and close lock signals to the monitoring host for long distance. If the unlock signal received by the monitoring host appears in the abnormal period, the signal is discriminated as a pirate and bedding signal, and the monitoring host immediately generates an alarm message, so that the relevant personnel can timely dispose of it to avoid financial loss.

  Chen Feilong (hereinafter referred to as "Boke"), deputy general manager of Wenzhou Boke Electronics Co., Ltd., told us that the electronic lock is a kind of lock that combines the electronic control part with the mechanical linkage or rotating parts. One is that the normally open electronic lock is mainly applied to the security door and the access door, and the other is the normally closed type.Electronic locks are mainly used for the control of security doors or high security doors. The design principle of the normally open electronic lock includes electromagnetic and mechanical components, most of which are designed according to the working principle of the electromagnet.

  Regarding the difference in the design of electronic locks between commercial and residential structures, Zheng Yongqing (hereinafter referred to as “Kaipou”), the general manager of Kaipao Door Control Equipment (Shanghai) Co., Ltd. simply gave us some explanations, commercial and civil electronics. The basic structure design of the lock is roughly similar, the biggest difference is the background management. The biggest requirement of the civil lock is that it needs to be as simple as possible in a safe and secure situation, not complicated, and does not need to use the outside world to help unlock the lock, such as a computer. Therefore, the operation should be solved directly by the button or voice prompt. Commercial applications require more back-end software operation management, and many conditions are required to deal with the possible conditions of a complex environment.
