Abstract

The utility model discloses a wireless door lock monitoring system, which comprises a door lock circuit, a routing circuit, and a monitoring server. The door lock circuit and the routing circuit respectively comprise a Zigbee wireless module, and signals are transmitted through a wireless network established by the Zigbee wireless modules in the routing circuit and the door lock circuit, and then are sent to the monitoring server through wire connection from the routing circuit. The wireless door lock monitoring system has low cost and large network capacity.

Description

Wireless door lock monitoring system

Technical field

The utility model relates to a kind of wireless door lock monitoring system, and in particular, it relates to a kind of door lock monitoring system based on the Zigbee wireless network.

Background technology

At present, itself does not detect sensing device the door lock that occurs on the market, can not monitor and network.To install sensing device additional if door lock monitored.Carrying out networking monitoring then needs by the security protection net, does not have the security protection net just can not carry out networking monitoring.So just have these shortcomings: installing the detection sensing device additional will increase cost; The equipment of installing additional is that the wired connection influence is attractive in appearance; As itself there not being the security protection net promptly can not carry out networking monitoring.

The utility model content

The utility model has overcome some shortcomings that exist in the prior art, and the door lock that uses in the native system itself possesses the Wireless Networking function, does not need to reinstall network and gets final product wireless networking.

System comprises door lock circuit, routing circuit and monitoring server, and door lock circuit comprises keyboard 1, buzzer 2, door lock controller 3, single-chip microcomputer 9, fingerprint module 6, REID module 7, power control circuit 8, battery 4, Zigbee wireless module 5.Routing circuit comprises router one 1, Zigbee wireless module 10.

The wireless network that routing circuit and door lock circuit are set up by the Zigbee wireless module is connected, and routing circuit passes through wireless or wiredly to be connected with server.Door lock circuit is by powered battery, and is low in energy consumption.According to user's needs can be on the door of needs monitoring the door lock of mounting strap Wireless Networking function, again by the free networking of Zigbee agreement.

Big and global general-use and intact opening based on the network capacity of Zigbee agreement, the utility model are used the Zigbee wireless module to set up Wireless Networking to transmit the beneficial effect that signal has following 3 points are arranged.

1. cost is low, wireless network connects and door lock circuit relies on powered battery because set up, and does not need other laying-out, and the Zigbee module is cheap, and the Zigbee agreement is exempted from patent fee, greatly reduces so compare price with prior art on the system synthesis basis.

2. low in energy consumption, the door lock module dissipation is low, and common No. 5 batteries of four joints can use more than 1 year.

3. network capacity is big, the network topology ability is strong, the Zigbee agreement has the big characteristics of network capacity, Zigbee can adopt star, bunch tree-like, a network structure networking, and can connect to form bigger network structure by arbitrary node, theoretically, its attachable node is nearly 65000.So network capacity is big and have a good network topology ability.

The specific embodiment

For those skilled in the art are more readily understood, come the utility model is described in detail below in conjunction with accompanying

drawing

1,2,3.

The Zigbee technology is a kind of short-distance radio network technology, so need the floor of monitoring that the router that is connected with the Zigbee wireless module is installed at every layer.The utility model has 4 kinds of modes of opening the door, and 4 kinds of modes of opening the door all can be sent signal that a door has been opened to server, to reach the purpose of monitoring behind door-lock opening.But signal all is the same from the process that door lock circuit is sent to monitoring server, so the following mode of only opening door with keyboard 1 input password comes the utility model specific embodiment is described.

The door lock of the band Wireless Networking function in the native system is installed on the door of needs monitoring.The user sends control signal by keyboard 1 input password, after control signal is handled through single-chip microcomputer 9, sends control signal and to door lock controller 3 door is opened.The wireless network that the signal that the door lock of door lock circuit generation simultaneously has been opened is set up by Zigbee module in Zigbee module in the door lock circuit 5 and the routing circuit 10 sends to router one 1, router one 1 sends to monitoring server by wired connection again with the signal that receives, and server shows the switch of then monitoring door lock.Also can send a signal when door lock is opened to buzzer 2, make buzzer 2 send the sound.When signal when monitoring server sends, signal is issued router one 1 by wired connection, router one 1 sends to signal Zigbee module 10 again, Zigbee module 10 by and Zigbee module 5 between the wireless network set up send signal to door lock circuit again.Door lock circuit is by battery 4 power supplies, and power control circuit 8 is used for the control to the door lock circuit power supply.

Other 3 kinds of modes of opening the door of the present utility model, the user also can pass through fingerprint-collecting, sends control signal by fingerprint module 6, and signal re-sends to door lock controller 3 with door-lock opening after handling through single-chip microcomputer 9.The user can also pass through rfid card, sends control signal by radio-frequency module 7, and signal re-sends to door lock controller 3 with door-lock opening after handling through single-chip microcomputer 9.The 4th kind of mode of opening the door of the present utility model, the user can be directly with door-lock opening by key.

The quantity of door lock circuit decides by the quantity of actual needs.
