Embodiment
With reference to shown in Figure 1.The present invention has adopted with the ARM11 processor as CPU, the function of CPU comprise sensor information processing and and the user between mutual.
Fig. 2 is the present embodiment main program flow chart.At first carry out initialization, carry out ZigBee then
Networking, set up a complete zigbee mesh network and comprise two steps: netinit, node add network, and wherein node adds network and comprises two steps again: network and network through existing father node through being connected with telegon.The foundation of Zigbee network is initiated by network coordinator, and any one zigbee node will be set up a network must satisfy following 2 requirements: 1. node is the FFD node, possesses the ability of zigbee telegon; 2. node does not also have and other
Network connects, when node is connected with other networks, what this node can only be as this network
Child node is because have and have only a network coordinator in a zigbee network.The user can set alarm threshold value after the networking, and each sensor node is started working afterwards, the humiture data are sent to microprocessor handle, if the data that collect surpass threshold value then microprocessor pass through GPRS
Send alarming short message to mobile phone.The user can give the microprocessor transmitting control commands through note or Internet, makes air-conditioning carry out work according to user's requirement.
Fig. 3 is a present embodiment Temperature Humidity Sensor node process flow diagram.At first ZigBee network to be added such as node adds back humiture collection timer and starts, and the humiture parameter is periodically gathered and it is sent.
Fig. 4 is a present embodiment ZigBee gateway program process flow diagram.The requirement of automatic network-building is to press
According to certain networking algorithm, any node all might become the center aggregation node in the system, and this aggregation node receives instruction and also sends it back feedforward information, and with other node switching information.If this center aggregation node is closed, then network is elected other nodes according to algorithm automatically and is taken over sb.'s job aggregation node, continues to accomplish the monitor task to total system.
Fig. 5 is that the present embodiment microprocessor is connected synoptic diagram with the cable network module.Being connected through interfaces such as MII, RMII of mac controller and PHY realizes.In IEEE802 consensus standard series, data link layer comprises LLC and MAC two sub-layer.Wherein MAC is responsible for accomplishing encapsulation, deblocking, transmission and the receiving function of Frame.The structure of Physical layer PHY has certain difference along with the difference of transfer rate.MII is the interface that connects data link layer and Physical layer.According to agreement, the function that requires the MII interface to have has: the read/write clock synchronization of data and frame separator; Independently read/write data passage is provided; For MAC layer and PHY layer provide corresponding management and support full-duplex mode, for networks such as 10BaseTest, from the output of Ethernet PHY chip is the required differential signal of transmission.But, also needing a network isolation transformer, network isolation transformer can play effects such as suppressing common mode interference, isolation circuit and impedance matching.ZigBee has defined 3 kinds of device types: telegon, routing node and terminal node, wherein terminal node does not have routing function, can dormancy when not transmitting and receiving data.Based on this, the ZigBee network struction 3 kinds of topological structures: in star topology, mesh topology and tree topology, the star topology, all end nodes are all communicated by letter with unique routing node, and the communication between the terminal node need be through the forwarding of routing node; Tree topology is the set of a plurality of star topology; In the mesh topology, any two equipment direct mutual communication in effective communication distance, node has mulitpath to arrive other nodes; The ability that self-organization, selfreparing are arranged; When certain bar link occurs fault, node can search out other paths and transmit, but the star-network power consumption is bigger; Because node needs continuous listens for network routing information, and is in running order for a long time.Be the serviceable life and simplification network complexity that prolong node, system terminal node and routing node adopt star topology, and routing node and coordinator node adopt mesh topology.
