An electronic lock is an electronic product that controls the work of the circuit or chip (access control system) through password input, thereby controlling the closing of the mechanical switch, and completing the task of unlocking and locking. Nowadays, the widely used electronic door locks are realized by programming with the chip as the core. The main components are: single chip microcomputer, clock, keyboard, LCD display, memory, demodulator, line multiplexing and monitoring, A/D conversion, buzzer and other units. There are many types of electronic locks, including simple circuit products, and chip-based products with higher cost performance. Nowadays, the widely used electronic code lock is realized by programming with the chip as the core. In the field of security technology, the electronic code lock with anti-theft alarm function replaces the traditional mechanical code lock, which overcomes the shortcomings of the mechanical code lock with less code and poor security performance, making the code lock both technically and in performance The above are greatly improved by one step. The principle of electronic locks is now more electronic locks are centered on the 51 series single-chip microcomputer (AT89051), equipped with corresponding hardware circuits, complete the password setting, storage, identification and display, drive the electromagnetic actuator and detect its drive current value, and receive the sensor Send alarm signal, send data and other functions. The single-chip microcomputer accepts the entered code and compares it with the password stored in the EEPROM. If the password is correct, the electromagnetic actuator is driven to unlock; if the password is incorrect, the operator is allowed to input the password from the beginning, up to three times; if it is all three times If it is not correct, the single-chip microcomputer will alarm the intelligent monitor via the communication line. The single-chip microcomputer sends each unlocking operation and the current value of the electromagnetic actuator's drive current to the intelligent monitor as status information, and also sends the alarm information received from the sensor interface to the intelligent monitor as a basis for intelligent analysis. Wireless electronic locks. Non-door lock electronic locks can be mainly used in logistics transportation, warehousing, milk transport vehicles, cash transport vehicles, refrigerated vehicles, drug delivery, tobacco delivery and other transportation areas. For example, it is used on the doors of cash transport vehicles, manhole covers of special vehicles and warehouse doors 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 Internet of Things related skills. The lock body has a built-in wireless transceiver module. When the lock body is opened and closed, the wireless transceiver module transmits the open and closed lock signals to the monitoring host over a long distance. If the unlocking signal received by the monitoring host appears in an abnormal period, the signal will be judged as a stolen opening and prying signal, and the monitoring host will immediately generate an alarm message so that relevant personnel can deal with it in time to avoid financial loss. The composition and application of electronic lock The core components of electronic lock: main board, clutch, fingerprint collector, password technology, microprocessor (CPU), intelligent emergency key. As a fingerprint lock, the most important thing should be the algorithm chip, that is, the heart is better, and you can do a good job of the mechanical part. If the recognition degree is high, anyone's fingerprint can be opened, then what is the use? Secondly, no matter what kind of lock, its essence is still a mechanical product. The fingerprint lock is a model of using modern high technology to transform traditional industries, and its core technology is first of all the grasp of mechanical technology. The mechanical technology is mainly composed of the following five aspects: 1. The reasonable design of the front and rear panels, that is, the appearance, is a sign that is significantly different from similar products. More importantly, the internal structure layout directly determines the stability and function of the product. This process involves multiple links such as design, mold making, and surface treatment. Therefore, manufacturers with more styles, relatively speaking, have stronger development and design capabilities and better stability. 2. Lock body. That is, the parent body of the bolt that can be connected to the door. The quality of the lock body directly determines the life of the product. This is the most core technology in mechanical technology and the lifeblood of fingerprint locks. It is also the most difficult problem to solve in the industry. Ninety-five percent of the existing production units cannot solve this problem, mainly through outsourcing. Powerful manufacturers have the ability to design and develop their own lock bodies. Therefore, the lock body is the core component that truly reflects the technical level of the manufacturer, and it is also the core technology of the entire fingerprint lock.
