Research Of Cow Health Monitoring System Based On Wireless Sensor Networks

Wireless sensor network(WSN) is composed of a large number of sensor nodes, data-centric self-organizing network, it can collect and process data. Cow is an important part of modern agriculture and animal husbandry, the traditional large-scale intensive farming are still using manual observation method, which not only brings a heavy burden on labor,but also easy to misjudge.In this paper, under the cow health status monitoring application background,we research deeply on node positioning technology, in order to enable it to meet the application needs more,and put forward solution for wireless sensor networks to monitor the health of the cows. This paper first introduces the research background, research status of key technologies in wireless sensor networks, research significance and wireless sensor networks related knowledge.Then, it research node localization technologies of wireless sensor networks. On the basis of comparing various key location algorithms, analyze the RSSI ranging error factors and give a solution that RSSI distance mean value correction. Meanwhile, put forward optimized APIT localization algorithm based on the corrected RSSI, and give the implementation process of algorithm.Based on the structure and function of cows health monitoring and positioning systems,this paper also proposes CC2530-based wireless sensor network monitoring system, gives the hardware design of wireless sensor network nodes which can collect cows temperature, as well as software design of each module.Finally, functional test on the temperature acquisition module and positioning module, the test results show that the proposed wireless sensor network solution and localization algorithm can exactly meet the need of health monitor system and localization in dairy cow.
