The so-called Intelligent Electronic Lock is a comprehensive product that combines electronic technology, integrated circuit design, a plethora of electronic components, and various innovative recognition technologies (including computer networking, embedded software cards, network alarms, and mechanical design of the lock body). The electronic lock is built around the 51 series microcontroller (AT89C51) and is equipped with corresponding hardware circuits to accomplish functions such as password setting, storage, recognition and display, driving electromagnetic actuators, detecting their drive current value, receiving alarm signals from sensors, and transmitting data.

Eastdo Technology, as a leading force in the PCB reverse engineering field, employs the latest EDA design software, professional technical personnel, and advanced process technology to clone single-layer, double-layer, and multi-layer PCB circuit boards. We can handle challenging tasks, such as reverse engineering of PCBs with blind buried vias. Currently, our company has successfully completed the reverse engineering and decryption of the PCB in the intelligent electronic lock. The following is a brief introduction to the intelligent electronic lock:

Features:

1. The key is a TM card, ensuring non-duplication for secure usage.
2. Supports single or double card access and universal card opening.
3. Detects the tongue position (door closed position), providing anti-prying and obstruction alarm features.
4. Equipped with light prompts, low voltage alarm, and the capability to connect to an emergency power supply.
5. The watch card is waterproof, heat-resistant, and convenient to carry.
6. Five-level management system, featuring a lock-clearing card that can reset all types of cards without disassembling the lock and reprogramming.
7. Emergency unlocking methods: external power supply and mechanical destruction emergency unlocking.
8. Two opening methods: automatic pop-up door and manual door opening.

Application Scope:

Suitable for use in offices, enterprises, schools, hotels, supermarkets, file cabinets, storage lockers, sauna cabinets, bathing center lockers, and bank rental safes.

In developed Western countries, intelligent electronic lock technology is relatively advanced and diverse, widely applied in intelligent access control systems to manage door access securely through various advanced and reliable technologies. In China, the overall level of intelligent electronic lock technology is still relatively low, and the cost remains high. The market mainly consists of keypad electronic locks, while keypad and card-key electronic locks have been imported and adopted the international advanced level. However, domestically developed electronic locks have not formed a stable market structure, with imitation of foreign advanced technology as the primary approach.

Replacing mechanical locks with intelligent locks is an inevitable trend. We have reasons to believe that intelligent locks, with their unique technological advantages, will lead the Chinese lock industry to better development, allowing more people to use them with confidence in various scenarios, and making our future safer.
