Is the electronic lock safe?

Many people ask if the electronic lock is safe? This article is for everyone to answer this question, electronic lock, with electromagnet (or micro-motor) and lock body as the implementation, electronic technology, integrated circuit design, combined with a variety of innovative identification technology (including computer network technology, built-in Comprehensive products such as software cards, network alarms, lock body mechanical design). 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.

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.


Basic structure of electronic lock

Nowadays, more electronic locks are centered on the 51 series single-chip microcomputer (AT89051), equipped with corresponding hardware circuits, complete the setting, storage, identification and display of the code, drive the electromagnetic actuator and detect the driving current value, and receive the sensor. Alarm signal, 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 not correct, the MCU will alarm the intelligent monitor via the communication line. The single-chip microcomputer sends the unlocking operation and the driving current value of the electromagnetic actuator to the intelligent monitor as the status information at the moment, 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, storage, warehousing, cash trucks, refrigerated trucks, drug delivery, tobacco transportation, etc. For example, it is used for 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 being 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.

   Electronic lock principle

   Electronic lock, it is also based on 51 series single-chip microcomputer (AT89051), with corresponding hardware circuit, complete password setting, storage, identification and display, drive electromagnetic actuator and detect its drive current value, receive sensor sent alarm Signal, send data and other functions. The MCU receives the entered code and compares it with the password stored in the EEPROM. If the password is correct, the electromagnetic actuator is unlocked; if the password is incorrect, the operator is allowed to re-enter the password, up to three times; if three times If it is not correct, the MCU will alarm the intelligent monitor through the communication line. The single-chip microcomputer sends the unlocking operation and the driving current value of the electromagnetic actuator as the status information to the intelligent monitor at this time, and also sends the alarm information received from the sensor interface to the intelligent monitor as the basis of the intelligent analysis.
