Description of drawings
Fig. 1 is network topology structure figure.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
According to the characteristics of air monitoring system, native system is selected hub-and-spoke configuration network as shown in Figure 1 for use.
Network is made of control node (telegon) and sensor node (for improving the convenience of setting up grid, adopting router to come replacement terminal equipment).
The major function of network has 5: (1) control node is set up network; (2) sensor node adds network; (3) sensor node transmits air speed data to controlling node; (4) the control node is uploaded air speed data; (5) host computer receives data and sending controling instruction.
The control node is born network coordination person's function, is responsible for developing and managing cordless communication network.After the networking success, the control node begins to receive the data of the sensor node transmission that adds network, and data are reached host computer.In addition, the control node also receives the steering order that host computer sends.Sensor node then is responsible for sending data to the control node.
The control node can be in the scope that own signal covers and a plurality of sensor node of not bearing network information transfer task between building network, carry out wireless connections.Begin building network after the control node starts, telegon carries out a series of session according to the regulation of ZigBee agreement in the networking process between each layer, finishes the parameter configuration of new network, sets up successfully until network.Afterwards, sensor node adds network, and each layer protocol of router and telegon is finished the configuration to self respectively, after this just can communicate by letter between the node in the network.
The detection of wind speed collection and control circuit comprise that wireless network node and sensor detect two parts.Air velocity transducer adopts three cup type air velocity transducer CM-FS2.Wireless network node adopts the CC2430 chip.
The software of air monitoring system mainly comprises wireless network transmission module node procedure and upper computer software program.The wireless network transmission module node procedure mainly is responsible for processing and the transmission of controlled wind speed data, also receives the steering order from host computer simultaneously.Upper computer software program major function is to communicate with the control node, and the information of receiving sensor node realizes sensor information reception, data demonstration, processing and functions such as analysis and steering order transmission.
The invention has the advantages that, utilize the ZigBee technology to replace the setting of traditional wiring, improved the dirigibility of networking and the extensibility of system, reduce maintenance cost.
