Electronic locks, with electromagnets (or micro-motors) and locks as the execution, will be electronic technology, integrated circuit design, combined with a variety of innovative identification technology (including computer network technology, built-in software cards, network alarm, locks mechanical design) and other integrated products. It is different from the traditional mechanical locks, without using metal keys, convenient to use, and highly confidential.

The basic structure of electronic lock

At present, most electronic locks are based on 51 series single-chip microcomputer (AT89051) as the center, with the corresponding hardware circuit, complete the password settings, storage, identification and display, drive the electromagnetic actuator and detect its driving current value, accept the alarm signal sent by the sensor, send data and other functions.

The MCU accepts the codes and compares them with the codes stored in EEPROM. If the codes are correct, it drives the electromagnetic actuator to unlock. If the codes are incorrect, the operator is allowed to input the codes from scratch up to three times. If the codes are incorrect, the MCU will report to the intelligent monitor through the communication line. Police. The SCM sends the status information of each unlocking operation and the current value of the electromagnetic actuator to the intelligent monitor, and sends the alarm information from the sensor interface to the intelligent monitor as the basis of intelligent analysis.

Wireless electronic locks. Non-door lock electronic locks, mainly used in logistics, warehousing, fresh milk delivery trucks, money carriers, refrigerated trucks, drug delivery, tobacco delivery and other transport areas. For example, it is used on the car door of the money carrier, the manhole cover of the special vehicle and the warehouse door to ensure the safety of the goods transported or guarded and to avoid theft. The electronic lock uses mechanical lock body to contact the Internet of Things related skills, the lock body built-in wireless transceiver module, when the lock body on and off, the wireless transceiver module will open and close signal long-distance transmission to the monitoring host. If the unlocking signal received by the monitoring host appears in an abnormal period of time, the signal will be identified as a stolen and prized signal, and the monitoring host will immediately alarm information, so that the personnel concerned can make timely disposal to avoid financial loss.

Chen Feilong, vice president of research and development center of Wenzhou Boke Electronics Co., Ltd. (hereinafter referred to as "Boke") tells us that electronic lock is a kind of lock which combines electronic control part with mechanical linkage or rotating parts. One is the normally open electronic lock mainly used in security doors, channel doors, the other is the normally closed electronic lock mainly used in the control of anti-theft doors or high security doors. Normally open electronic lock design principle includes electromagnetic and mechanical components, most of which are designed according to the working principle of electromagnets.

What is the difference between electronic locks in commercial and civil structure design? Zheng Yongqing, general manager of Kaibao Gate Control Equipment (Shanghai) Co., Ltd. (hereinafter referred to as "Kaibao") gives us some simple explanations. The basic structure design of commercial and civil electronic locks is similar, the biggest difference is the background management. The greatest requirement of civil locks is that they need to be as simple as possible, not complicated, and do not need outside help to unlock, such as computers. Therefore, the operation should be directly solved by buttons or voice prompts. Business needs more background software operation and management, and requires a lot of conditioning to deal with complex environments that may arise.
