Description
Technical field
The present invention relates to a kind of mixed networking based on ZigBee and RS485 and its method of work and application, belong to electronics
The technical field of information communication.
Background technology
Gate control system is the system being managed to exit and entrance, and it is developed on the basis of traditional mechanical door lock
And come, either the electronic password lock gate inhibition at initial stage still have now been attained wide variety of RFID sensing cassette gate inhibition and
Emerging finger-print type gate inhibition and iris gate inhibition be unable to do without the network delivery of card information, and gate inhibition's networking is played to systematic function to pass
Important effect, is especially installed to the data throughout and stability and system construction of system.
Networking of the prior art is largely to use RS485 communication modes.Chinese patent CN105528818A discloses one
Kind be based on gate control system, the system include server, communication converter, controller, memory, card reader, electromagnetic lock, go out by
Button, fire-fighting link module and stand-by power supply；Memory is used for the emergency such as power failure suddenly as second data storage method
The storage of lower data.Communication converter is responsible for carrying out RS485 communication conversions, and fire-fighting link module is responded for fire protection warning, standby
Unit mouthful access control equipment is powered when being responsible for unexpected have a power failure with power supply.
Constructing communication network communication distance is carried out using RS485 long, can carry out multichannel communication multiple telecommunication, many gate inhibitions' work, in low speed, short
Distance, glitch-free occasion can use common twisted-pair feeder；In high speed, Long line transmission, using impedance matching (generally
120 Ω) RS485 private cables (STP-120 Ω), interference rugged environment under use armored type paired shield cable
(ASTP-120Ω)；But RS485 is typically half-duplex operation, communication distance is easily interfered within 1200 meters, impedance
Matching influences larger to communication efficiency, and then reduces a part of power.
During for live gate inhibition's construction such as building, communication line long RS485 is to construction requirement threading and cloth
Line requires comparatively laborious, and to the wall damages of building than larger, wiring can be effectively reduced by the method for radio communication
Difficulty and the destruction to wall, eliminate a large amount of manpowers and wire rod cost, with low cost, and it is good that central controller updates real-time.
There is the mode networked including WIFI with ZigBee in existing wireless communications gate inhibition's technology.Chinese patent
CN104504790A discloses a kind of radio entrance guard control system, mainly includes master server layer, embedded server layer, WiFi
Transport layer, ZigBee telegons key-course, ZigBee node key-course Pyatyi level, each level can flexibly arrange in pairs or groups to be formed 6 kinds fit
Answer the big mini system of different application scene.System that employs ZigBee and WiFi home control network communication protocols and combine embedded processing
Device integrated management gate control system.
The gate inhibition of wireless communication network is high to each radio node QoS requirement, requires high to network delay, single nothing
The cost of line communication node is higher, for the gate control system with multiple gates, if one communication node of each node installation,
Cost is greatly increased, and is also wanted extra to the supply line of each node and connected up.
The content of the invention
In view of the shortcomings of the prior art, the present invention provides a kind of mixed networking based on ZigBee and RS485.
The present invention provides a kind of method of work of the above-mentioned mixed networking based on ZigBee and RS485.
Present invention offer is a kind of to include the gate control system of the above-mentioned mixed networking based on ZigBee and RS485.
Term explanation：
1st, ZigBee gateways (Co-ordinator), is to start a kind of equipment with Configuration network, is the centromere of network
Point a, ZigBee-network only allows have a ZigBee gateway；

Standby, ZigBee-network can have multiple ZigBee routing nodes；
3rd, ZigBee terminal devices (End Device), the equipment for performing concrete function.
3 kinds of equipment above can be divided into full-function device (FFD) and half function device (RFD) according to functional completeness.Its
In, full-function device can be as telegon, router or terminal device, and half function device can only be used as terminal device.One
FFD can communicate with the other FFD of multiple RFD or multiple, and a RFD can only communicate with a FFD.
The technical scheme is that：
A kind of mixed networking based on ZigBee and RS485, including zigbee gateways, zigbee terminal nodes and RS485
Gating device；Mixed networking uses tree network topology structure, and ZigBee gateways are the root node of tree network；Zigbee gateways lead to
Zigbee terminal nodes are crossed to be connected with RS485 gating devices.
Zigbee gateways be network central controller, to whole ZigBee systems carry out network management, be responsible for formed and
Control the flow of each member in network topology, coordination network.
Zigbee terminal nodes are responsible for sending and receiving the terminal of the network information and are responsible for conversion and the place of 485 signals
Reason.
RS485 gating devices are the control nodes of hybrid network, are responsible for the transmitting-receiving of 485 signals, receive and come from ZigBee terminals
The authorization message and command information of node；The working condition for sending RS485 gating devices controls bottom to ZigBee terminal nodes
Hardware device (control authorization message writes flash storage, card reader work, door interlock switch etc.)；Each ZigBee terminal sections
Point has RS485 communication capacities, and multiple RS485 gating devices carry out RS485 communications with nearest ZigBee terminal nodes, realized whole
The networking of individual gate control system.
Choosing is had according to the present invention, the area that each zigbee terminal nodes are in charge of region is 10 ㎡.If gate inhibition's network
Distribution distance can carry out cable access network than larger.
Choosing is had according to the present invention, the zigbee terminal nodes pass through ZigBee routing nodes and the zigbee gateways
Connection；Between zigbee terminal nodes and zigbee routing nodes, pass through between zigbee routing nodes and zigbee gateways
2.4GHz wireless zigbee communication protocols connection.ZigBee routing nodes are responsible for the flow of a part of network memberses of management and control
(ZigBee terminal nodes are not to be all directly connected to zigbee gateways, and part ZigBee terminal sections are route by ZigBee
Node is connected to ZigBee gateways, so that the quantity for the ZigBee node for being connected to gateway is reduced, while being also just responsible for control
The flow of part), the control command of zigbee network gateway is sent and received, is responsible for the transfer and transmission of the network information.
Choosing is had according to the present invention, described zigbee gateways are realized based on ARM Cortex-A9.ARM Cortex-A9
Internal memory reaches as high as 8M, the L1 cache arrangements of 16,32 or 64KB 4 tunnels association is supported, for optional L2 caches control
