【摘要】：目前我国畜禽大多采用封闭式养殖,养殖量位居世界前列。畜禽的产量、畜禽产品的品质受环境影响较多。有效的畜禽舍监控可以改善畜禽舍环境,优良的畜禽舍环境可以提高畜禽的产量以及畜禽产品的品质进而取得更大的经济效益。传统的畜禽舍监控系统一般采用有线方式,布线繁琐、成本高、维护困难、测量的精度也比较低。无线传感器网络的出现和发展,为畜禽舍的监控提供了新的方向,使畜禽养殖的产业化、自动化成为了可能。根据长春市明锐养殖场的实际情况,研究并设计基于ZigBee技术的畜禽舍环境监控系统。影响畜禽生长、发育、繁殖、健康和畜禽产品的生长量(蛋、奶、肉、毛)的因素比较多,但是畜禽舍内部的环境对其影响尤为明显。生长环境的好坏直接决定着畜禽生长的好坏,同时也直接关系到经济利益,所以改善畜禽舍环境尤为重要。论文在分析了畜禽舍监控和无线传感器网络在国内外发展现状的基础上,结合国内畜禽舍监控的实际情况,确定监控的环境因子和无线通信方案。并提出了以DSU1115-0601模块为核心的基于ZigBee技术的畜禽舍环境监控系统的设计。根据监控的需要,开发了以DSU1115-0601模块为硬件核心的ZigBee网络节点,节点可以驱动各种传感器。传感器节点能够实时的采集畜禽舍内环境的各因子的数据,然后把采集到的数据传给路由节点,路由节点会把采集的数据传给网络协调器,网络协调器通过串口把数据传送到上位机的监控中心。上位机的监控中心是一个友好的人机交互界面,该界面可以实时的显示上传来的数据,并可以用曲线或者柱状图等形式直观的显示出来,同时该界面还具有历史查询和打印输出功能。而且当有环境因子数据不在合理范围内时,监控中心会发出报警信号,这时PC机可以通过控制执行设备来调控畜禽舍内各环境因子,从而使畜禽舍环境一直处于一个相对稳定的适合畜禽生产的状态。通过性能测试,证明系统有效稳定且可靠,能够满足畜禽舍监控的需要。
[Abstract]:At present, most of China's livestock and poultry use closed culture, breeding volume ranks among the top in the world. The output of livestock and poultry and the quality of livestock and poultry products are affected by environment. The effective monitoring of livestock and poultry house can improve the environment of livestock house, and the good environment of livestock house can improve the output of livestock and poultry and the quality of livestock and poultry products, and then obtain more economic benefits. The traditional monitoring system of livestock and poultry house is usually wired. The wiring is tedious, the cost is high, the maintenance is difficult, and the precision of measurement is low. The emergence and development of wireless sensor network (WSN) provides a new direction for the surveillance of livestock and poultry houses, and makes the industrialization and automation of livestock and poultry breeding possible. According to the actual situation of Changchun Mingrui farm, the environment monitoring system of livestock house based on ZigBee technology is studied and designed. There are many factors affecting the growth, development, reproduction, health and the growth of livestock and poultry products (egg, milk, meat, hair), but the environment inside the livestock house has a more obvious effect on it. The quality of growth environment directly determines the quality of livestock and poultry growth, but also directly related to economic interests, so it is particularly important to improve the environment of livestock and poultry houses. Based on the analysis of the present situation of livestock house monitoring and wireless sensor network at home and abroad, combined with the actual situation of domestic livestock house monitoring, the paper determines the environmental factors and wireless communication scheme. The design of environment monitoring system based on ZigBee technology based on DSU 1115-0601 module is put forward. According to the need of monitoring, a ZigBee network node with DSU1115-0601 module as the hardware core is developed, which can drive various sensors. The sensor node can collect the data of every factor in the environment of the livestock and poultry house in real time, and then transmit the collected data to the routing node, and the routing node will transmit the collected data to the network coordinator. The network coordinator transmits the data to the monitoring center of the host computer through serial port. The monitoring center of the upper computer is a friendly human-computer interface. The interface can display the data transmitted from the computer in real time, and can be displayed intuitively in the form of curves or histograms. At the same time, the interface also has history query and print output function. Moreover, when there is an environmental factor data that is not within a reasonable range, the monitoring center will issue an alarm signal, and the PC can control the environmental factors in the livestock and poultry house by controlling the execution equipment. Thus, the environment of livestock house has been in a relatively stable state suitable for livestock production. The performance test shows that the system is effective, stable and reliable, and can meet the needs of livestock house monitoring.
