Wireless door lock network networking principle: The wireless networked door lock system communication network is divided into two parts: wireless communication network and wired communication network. The door lock and the wireless base station (LA171) communicate via wireless signals, and the wireless base station (LA171) communicates with the management software via a wired Ethernet LAN. Generally, each floor can form a wireless communication network. There is one wireless base station (LA171), several wireless bridges (LA172), and a large number of wireless networked door locks (L5207-245, etc.). The wireless network is created by the wireless base station (LA171), and the wireless bridge (LA172) and the wireless door lock are automatically routed in the proximity principle.

Wireless networked door lock features:
1. Wireless networking: The product is developed based on the most advanced wireless networking technology open platform at this stage, and uses the 2.4GHz ISM band for communication. Each floor door lock communicates wirelessly with a wireless base station (LA171). Only one wireless base station (LA171) is required to communicate with the computer via TCP/IP protocol on each floor.
2, the power supply is simple: the door lock is powered by 4 alkaline dry batteries, the door lock and the outside world do not need any connection line, easy to install, ready to use.
3. Reliable communication: Carrier sense multiple access/collision prevention (CSMA/CA) technology is adopted to prevent multiple door locks from simultaneously transmitting data to form interference, or interference from other wireless devices.
4. Communication security: Supports the wireless transmission international standard security suite. The wireless transmission data uses AES-128 advanced encryption algorithm to provide security for wireless communication.
5. Network door locks do not affect each other: When the wireless network is interrupted, the basic function of the door lock is normal. When the network is normal, the door lock will report the opening record during the interruption.
6, real-time monitoring: the computer can monitor the switch state of the door lock and the battery state of the door lock in real time, to facilitate the management of the door lock and replace the battery.
7, the clock is accurate: the door lock has a clock inside, and the computer software can calibrate the clock in real time to ensure the accuracy of the event.
8. Remote control: In an emergency, the computer can control the opening and closing of the door lock. Achieve emergency handling of events.
9, one card multi-door, one multi-card: one card can open multiple door locks for management. Each door lock can use multiple cards to open the door.
10, efficient door opening, one card multi-use, support "one card", easy to manage.

Wireless networked door lock and computer information exchange:
1. Two-way communication: The computer can issue commands and data to the door lock through the wireless base station (LA171), and the door lock can also send data to the computer.
2. Computer operation on the door lock data: The computer can wirelessly download the card, delete the card, update the time and other data operations through the wireless base station (LA171).
3, computer remote control of the door lock: the computer through the wireless base station (LA171) can remotely control the door lock always open, after the card is restored. The remote controllable door lock is also closed.
4. Computer and door lock information exchange: The computer can check the battery status of the door lock and the switch of the door lock through the wireless base station (LA171); it can also query the card information in the door lock.
5. Door lock report data: When the door lock is opened, the door open record (card number, door opening time) will be sent to the computer to facilitate real-time monitoring of the door by the main station. The door lock will report the door lock status (switch, battery) to the computer in real time.
6. The computer corrects the door lock time: the computer can query the time of the door lock through the wireless base station (LA171), and then the time of the door lock can be calibrated by the computer to ensure the correctness of the event record.
7. Emergency handling: It can be linked with fire alarm system and anti-theft alarm system. When a fire occurs, the access door lock of the relevant area is opened; if the burglar alarm signal is received, the access door of the relevant area is blocked.
