Embodiment two
The scenery control method based on ZigBee is proposed in embodiment one, then proposes and can realize in the present embodiment
The scenery control system based on ZigBee of above-mentioned scenery control method, the control system include gateway and the gateway base
The source device communicated in ZigBee-network and target device, in the control system：
The gateway is instructed for setting up the networking of private network for sending to the source device and the target device,
Sequence of scenes number is sent to the source device, scene configuration letter corresponding with the sequence of scenes number is sent to the target device
Breath, the scene configuration information include operational order corresponding with the sequence of scenes number；
The source device is used for obtaining sequence of scenes number from the gateway, broadcasts predetermined registration operation in the private network
Sequence of scenes number, and after triggering predetermined registration operation, sequence of scenes number is sent to target device；
The target device is used for obtaining scene configuration information from the gateway, and is receiving predetermined registration operation scene sequence
After row number, operational order corresponding with the default scene configuration information is executed.
In force, the scenery control system includes gateway, and the source being connected with gateway based on ZigBee communication agreement
Equipment and target device.In typical application scenarios, at least include a gateway in the scenery control system, as privately owned net
The coordinator of the network network structure to private network is managed；At least one source device and at least one target device.
ZigBee defines the equipment of 3 types, and every kind of equipment has the functional requirement of oneself：
ZigBee coordinators (Co-ordinator), are to start a kind of equipment with Configuration network, are the centromeres of network
Point, a ZigBee-network have only allowed a ZigBee coordinator；
ZigBee routers (Router), are a kind of equipment that supports and associate, can forward the message to other equipment,
ZigBee-network or tree network can have multiple ZigBee routers, ZigBee Star Networks not to support ZigBee routers；
ZigBee terminal units (EndDevice), execute the equipment of concrete function.
3 kinds of above equipment can be divided into full-function device (FFD) and half function device (RFD) according to functional completeness.Its
In, full-function device can be used as coordinator, router or terminal unit, and half function device can only be used as terminal unit.One
FFD can FFD other with multiple RFD or multiple communicate, and a RFD can only be communicated with a FFD.
The ZigBee communication network being made up of above-mentioned three kinds of equipment is being carried out as shown in previous embodiment step 101 is to 103
The step of before, it is necessary first to carry out the operation of netinit, specific initialization step includes：
1. determine network coordinator, first determine whether whether node is FFD nodes, then judge this FFD node whether at which
Whether coordinator be present in his network or in network.By active scan, a beacon request order (Beacon is sent
Request command), scanning time limit (T_scan_duration) is then set, if all do not had within the scanning time limit
Detect beacon, then FFD is considered as in its pos without coordinator, then now can just set up the ZigBee nets of oneself
Network, and the coordinator as this network is constantly be generated beacon and is broadcasted.
2. channel scan procedure is carried out.Including two processes of energy scan and active scan：First to specified channel or
The channel of person's acquiescence carries out energy measuring, to avoid possible interference.Letter is carried out to measured energy value incrementally
Road sorts, and abandons so much energy value beyond allowing the channel of energy level, selects to allow the channel of energy level simultaneously
It is available channel to mark these channels.Then active scan, network information search node communication radius in are carried out.These information
Broadcasted in the form of beacon frame in a network, node obtains these beacon frames by active channel scan mode, then according to this
A little information, find a best, relatively quiet channel, by the result for recording, select a channel, the channel exist
Minimum ZigBee-network, preferably without ZigBee equipment.During active scan, mac layers will abandon the service of phy layer datas
The all frames in addition to beacon for receiving.
3. network ID is set.After finding suitable channel, coordinator will for network select network identifier (PANID,
Value<=0x3FFF), this ID must be unique in the channel for being used, and can not conflict with other ZigBee-networks,
And can not be broadcast address oxFFFF (this address is reserved address, it is impossible to using).PANID can be by intercepting other networks
ID then select the mode of an ID that will not conflict obtaining, it is also possible to the channel of artificial invisible scanning was determined not later
PANID with other network conflicts.There are two kinds of address patterns in ZigBee-network：Extended address (64) and short address (16
Position), wherein extended address is distributed by IEEE tissues, for unique device identification；Short address is used for equipment mark in local network
Know, in one network, the short address of each equipment must be unique, and is passed through by his father's node distribution when node adds network
Communicated using short address.For coordinator, short address is typically set at 0x0000；
After the completion of previous step, the ZigBee mesh networks with regard to successful initialization wait for the addition of other nodes afterwards.
The most strong father node of signal in the range of choice (including coordinator) is added network when node networks, after success, a net will be obtained
Network short address simultaneously carries out sending and receiving for data by this address, and network topology and address will be stored in respective
In flash.
After initialization operation is carried out, source device and target device add network as network node by coordinator：
After node coordinator determines, node sets up connection addition network firstly the need of with coordinator.In order to set up connection, FFD is saved
Point needs to file a request to coordinator, and coordinator according to circumstances decides whether to allow which to connect after receiving the connection request of node
Connect, then the node of request connection is responded, node is set up with coordinator after being connected, and could realize the transmitting-receiving of data.Tool
The flow process of body can be divided into below step：
1. Network Search coordinator.First can active scan search ambient network coordinator, if scanning the time limit in
Detect beacon, then coordinator will be obtained for information about, at this moment just connection request is sent to coordinator.Selecting properly
Network after, mac layers will be asked to the PIB such as phyCurrentChannel, macPANID of physical layer and mac layers category in upper strata
Property is arranged accordingly.If be not detected by, after certain interval of time, node initiates to scan again.
2. association request command (Associate request command) is sent.Association request command is sent by node
Respond immediately to an acknowledgement frame (ACK) after receiving to coordinator, coordinator, while connection indication is sent to its upper strata,
Represent the connection request for having received node.But it is not intended that having built up connection, only represent that coordinator has been received
The connection request of node.After the upper strata of the mac layers of coordinator receives connection indication, by the resource situation according to oneself
(memory space and energy) decides whether the addition request for agreeing to this node, and then the mac layers to node send response.
3. mediators handle is waited.After node receives the ACK that coordinator adds request command, node mac will wait one
The section time, receive the connection response of coordinator.Within the predetermined time, if receiving connection response, it by this respond to
Its upper strata notice.And coordinator to node mac layers send response when one wait-for-response time (T_ can be set
ResponseWaitTime) waiting coordinator to add the process of request command to which, if the resource of coordinator is enough, coordinator
To the short address of node distribution one 16, and the connection response order comprising new address and successful connection state can be produced, then
This node is successfully set up connection and can start to communicate with coordinator.If coordinator resource is not enough, node to be added will
Solicited message is resend, is directly networked successfully.
4. data request command is sent.If coordinator agrees to that node is added in response time, then will produce association
Response command (Associate response command) simultaneously stores this order.After response time, node sends number
Respond immediately to ACK after receiving to coordinator, coordinator according to request command (Data request command), then by storage
Node is issued in associated response order.If after response time is arrived, coordinator does not also decide whether to agree to that node is added, then
Node will attempt to extract associated response order from the beacon frame of coordinator, can be to network successfully, otherwise again if success
Solicited message is sent until networking successfully.
5. reply.After node is subject to associated response order, an acknowledgement frame (ack) is replied to coordinator immediately, to confirm
Connection response order is received, now node will preserve short address and the extended address of coordinator, and the MLME of node is upwards
Layer sends connection and confirms that primitive, notice association add successful information.
Propose source device and target device to obtain from gateway in step 201-202,301-303 in embodiment one
The step of information realization self information updates, and the equipment in order to make gateway accurately can update request to initiation be carried out back
Multiple, the equipment for needing order to initiate to update request carries the device identification of itself in the request, specifically each device identification
Including 2 kinds of following addresses：
1.IEEEMAC addresses：
This is the address of a kind of 64, and this address is allocated by IEEE tissues, for unique mark equipment, the whole world
There is identical MAC Address without any two equipment.In ZigBee-network, it is extended address to be also sometimes MAC Address.
2.16 position short address：
