Step 2, open gateway node, the all the sensors node enters negotiation phase, gateway node sends data collection cycle in the mode of broadcast to all the sensors node, in the information broadcast process, sensor node is set up neighbor table, independently forms network, and sets up route, sensor node is that unit organization becomes a plurality of wireless sensor networks with bunch head simultaneously, and sends feedback information to gateway node synchronously;
After step 3, gateway node received the feedback information of all the sensors node, negotiation phase finished, and working stage is closed and entered to gateway node notice all the sensors node;
Step 4, enter working stage after, all the sensors node is regularly waken up and is carried out data acquisition all according to the determined data collection cycle of negotiation phase, and gives separately leader cluster node with the corresponding Monitoring Data synchronized transmission gathered; The Monitoring Data that each sensor node was gathered in bunch head was collected bunch and to all collected Monitoring Data packings is committed to gateway node; After gateway node receives the Monitoring Data of described all the sensors node, reinform described all the sensors node and close, enter next data collection cycle;
Step 5, gateway node are sent to the communication server with the Monitoring Data of all the sensors node, and the communication server unpacks data, and deposit database in for user or expert system inquiry;
Step 6, expert system are analyzed all Monitoring Data that deposit database in according to the chamber crop growth model, specifically according to the concrete crop in greenhouse in different growing stages to moisture content, temperature, humidity and CO
2Concentration needs, and makes and whether pours water, lowers the temperature or heat, increases CO
2The corresponding guidance program of concentration, expert system sends operation instruction information and/or early warning information by the communication server to wireless sensor network.
After the communication server described in the step 5 receives the Monitoring Data of all the sensors node, the Monitoring Data received after encapsulation and encoding process, is ceased to peasant household's mobile phone transmitting supervisory data SMS by the gsm wireless communication module.
After the communication server described in the step 6 is received early-warning conditions management information that expert system sends and wireless sensor network is carried out corresponding early warning and be provided with, when real-time Monitoring Data reached the threshold value that early-warning conditions management information sets, the early warning short message of the communication server after with early warning information encapsulation and coding was sent to peasant household's mobile phone by the gsm wireless communication module.
When the expert system described in the step 6 sends operation instruction information or early-warning conditions management information to wireless sensor network, expert system sends to the communication server with setting measurement parameter steering order earlier, send to gateway node by the communication server again, gateway node is notified all the sensors node in the mode of broadcast again, and activates all buttoned-up sensor nodes.
The invention has the beneficial effects as follows: 1, reasonable in design and use easy and simple to handle, practical.2, can guarantee effectively that the efficient information between the wireless sensor network and the communication server transmits, can realize that control information and wireless sensor network detect the unobstructed circulation of data message, thereby can in time, accurately obtain the real time data that each sensor node is monitored in the greenhouse to greatest extent, and according to after detecting data and making concrete operation instruction suggestion or early warning and be provided with, can at a high speed steering order be sent to sensor node, thereby significantly improve the yield and quality of crops.
