【摘要】：近年来,禽畜类流行性疾病不断爆发和传播,H7N9等病毒已严重威胁到人类的生命安全,专家认为这与养殖环境的不断恶化关系密切,因此亟待需要加强禽舍环境的监控。针对此现状,本文设计了一套基于无线传感网的养禽环境监控系统。主要内容如下:(1)该系统以无线传感网为通信基础,ZigBee技术为通信手段,主要分为上位机子系统和下位机子系统。下位机子系统包括ZigBee节点和网关,搭载有各类传感器的终端节点通过ZigBee网络将采集数据发送至协调器节点,协调器节点一方面将数据上传至上位机,一方面通过串口将数据发送至GPRS模块,再由后者将数据发送至手机终端。上位机子系统主要包括上位机软件和Android手机客户端软件的设计与开发,上位机软件管理、分析并保存来自协调器节点的数据,Android手机客户端不仅实时接收环境数据,而且在报警发生时发送调控指令给终端节点,从而实现了养禽环境远程实时监控。(2)本文主要完成的工作包括两方面。一方面是下位机系统主要完成了系统的硬件设计和器件选型,主要包括:硬件电路的设计,主芯片和各类传感器的选型。另一方面是上位机系统主要完成了包括:软件开发环境的搭建,系统子模块程序的编辑,软件监控界面的功能设计等。最后,完成了对系统的测试和数据分析,利用最小二乘法对数据进行线性拟合,保证了数据的测量精度。(3)实验测试研究。对设计的系统进行了实验,测试结果表明本系统开发设计简单可靠,组网灵活方便,功耗低且监测数据精确,不仅解决了传统监控系统的缺陷,而且降低了系统设计成本,提高了生产效率和经济收益,促进了家禽养殖业的健康持续发展。
[Abstract]:In recent years, the outbreak and spread of livestock epidemic diseases such as H7N9 virus have seriously threatened the safety of human life, experts believe that this is closely related to the deterioration of the breeding environment. Therefore, it is urgent to strengthen the monitoring of poultry house environment. This paper designs a wireless sensor network based environment monitoring system for poultry. The main contents are as follows: 1) this system uses wireless sensor network as the communication base and ZigBee technology as the means of communication. It is mainly divided into upper computer subsystem and lower machine sub-system, which includes ZigBee node and gateway. Terminal nodes with various sensors send the collected data to the coordinator node through the ZigBee network. On the one hand, the coordinator node uploads the data to the host computer. On the one hand, the data is sent to GPRS module through serial port. Then the latter sends the data to the mobile phone terminal. The upper computer subsystem mainly includes the design and development of the upper computer software and the Android mobile phone client software, and the upper computer software management. The Android mobile phone client not only receives the environment data in real time, but also sends the control command to the terminal node when the alarm occurs. Thus realized the poultry environment remote real-time monitoring. 2) the main work of this paper includes two aspects. On the one hand, the lower computer system mainly completes the hardware design and device selection of the system. It mainly includes the design of hardware circuit, the selection of main chip and various sensors. On the other hand, the host computer system mainly completes the construction of software development environment, the editing of system sub-module program. Finally, the test and data analysis of the system are completed, and the least square method is used to fit the data linearly. The test results show that the system is simple and reliable, easy to network, low power consumption and accurate monitoring data. It not only solves the defects of the traditional monitoring system, but also reduces the system design cost, improves the production efficiency and economic benefits, and promotes the healthy and sustainable development of poultry industry.
