Door-lock system based on Zigbee wireless communication technology and control method thereof

Abstract

The invention discloses a door-lock system based on a Zigbee wireless communication technology and a control method thereof. The door-lock system comprises a remote user control terminal, a wireless base station and multiple door locks, wherein the wireless base station is in data communication with the remote user control terminal through a wired network; and data communication between the door locks and the wireless base station is realized through a wireless network. The control method comprises the following steps: a wireless module receives electronic lock card information and stores the information into a storage after a card of a user is read; the wireless base station detects whether a network channel is idle, and transmits the information to the remote user control terminal when the channel is idle; the control terminal compares the information with the recorded authorization user information after receiving the information, and if the information accords with the authorization user information, feeds back an instruction to control the door locks to unlock and records the unlocking time, otherwise records the fault time and alarms a manager. According to the system and method, an interior communication network is established by using the Zigbee technology, and the system is convenient to install and high in expansibility.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a door lock system based on Zigbee wireless communication technology and a control method thereof. Background technique [0002] There are two types of traditional electronic door locks, one is communication between the bus through RS485, and the other is TCP / IP networking type. All information of the two types of electronic door locks must be input into the computer first, and then read and write. All the information on the card must also be read by the reader, and then connected to the terminal computer to work. Since each door needs to be wired and connected to the host, the wiring is complicated; and the disadvantage of wired transmission is that there are more hardware failures caused by wire layout, and the transmission cost of the transmission line is relatively high. For the buildings that have been put into use, the decoration and integrated w...

Problems solved by technology

Since each door needs to be wired and connected to the host, the wiring is complicated; and the disadvantage of wired transmission is that there are more hardware failures caused by wire layout, and the cost of transmission line transmission is higher

For the buildings that have been put into use, the decoration and integrated wiring have been completed. When installing the electronic door lock system, wiring needs to be carried out independently. The construction volume is large and the installation time is long, which affects normal work and life.

These shortcomings have seriously hindered the application of fieldbus in electronic door locks, and the application of electronic door lock technology based on wireless technology will be imperative

[0003] At present, the more popular short-distance wireless communication technologies mainly include infrared (IrDA: Infrared Data Association) technology, home radio frequency (HomeRF) technology, IEEE802.11 technology, and Bluetooth (Bluetooth) technology. High power consumption, complex protocol, limited transmission distance and poor anti-interference ability, etc., are not suitable for home networks that require low cost and low power consumption
