Design Of Environment Monitoring System For Poultry Based On Wireless Sensor Network

In recent years,the epidemic diseases of poultry were continuing to break out and spread,H7N9 and other viruses have a serious threat to human life safety,experts believe that this is closely related to the deterioration of the breeding environment,so it is so urgent for us to strengthen the poultry house environment monitoring.In view of this situation,this paper designs a set of monitoring system based on wireless sensor network.The main contents are as follows:(1)The system uses the wireless sensor network as the communication foundation,ZigBee technology as the communication means,mainly divides into the host computer system and the lower machine subsystem.The lower machine subsystem includes ZigBee nodes and gateways.The terminal nodes carrying all kinds of sensors send the collected data to the coordinator nodes through the ZigBee network.On the one hand,the coordinator node will upload data to the host computer;on the one hand,it will send data to the GPRS module through the serial port,and then the latter will send data to the mobile terminal.The host computer system mainly includes the design and development of the host computer software and the Android mobile client software.The host computer software manages,analyzes and saves the data from the coordinator node.The Android mobile client not only receives the environmental data in real time,but also sends control instructions to the terminal node when the alarm signal occurs,in order to achieve the long-term and real-time monitoring of poultry environment.(2)The main work of this paper includes two aspects.On the one hand,this paper mainly completes the hardware design and device selection of the aquaculture environment system in the lower computer system,including the design of the hardware circuit and the selection of the main chip and all kinds of sensors.On the other hand,host computer system mainly completed,including:software development environment to build;system sub-module program editing,the functional designs of software monitoring interface.Finally,the test and data analysis of the system is completed,and the data is linearly fitted by the least squares method to ensure the measurement accuracy of the system data.(3)Experimental test.The design of the system was experimented,the experimental results show that the system is simple and reliable,flexible and convenient in networking,having low power consumption and accurate monitoring data.It not only solves the shortcomings of the traditional monitoring system,but also reduces the cost of system design,improves the production efficiency and economic benefits,and promotes the intelligent development of poultry breeding industry.
