Design And Implementation Of Monitoring System For Multiple Cows Body Temperature

The body temperature is one of the important parameters for cow health status and also is one of great significance reference for disease diagnosis and treatment.The data collection of cow body temperature by manual can't be real-timing and sometimes has errors lead to a lot of difficulties to management.In view of development of computer technology and applications in the agriculture,based on the current mainstream of Wi-Fi,real-time monitoring system is applied to inspect the variation of cow body temperature in this paper.The digital temperature sensor DS18B20 is used to collect cow's aural temperature,communicated with ESP8266 EX module that is integrated Cadence L106,32-bit microcontroller(MCU),a 16-bit RSIC with the complete system and self-contained Wi-Fi networking capabilities through one-wire connector.At the first time ESP8266 EX module must be configured by SmartConfig protocol with AP's(Access Point)parameters which aiming to be slinked with AP.Once the connection is successfully established,the temperature data will be sent to MCU.After received,MCU packs data and parameters send to server through UDP protocol.And the data collected have been stored in MySQL database respectively in different cow.The soft system programmed with java language can achieve real-time acquisition,storage,display and inquiry of cow's temperature data.The asynchronous communication models in view of java nio class have been used to solve the masses of service requests delivered and the request congestion excluded.The results of experiment show that errors of the proposed device are ±0.4 range of 30?-50?,the proper transfer distance of sensor node is 80 m,and the loss rate of network passage is 4.42%.The power consumption is decreased with collecting time and sleep mode.It is proved that the characteristic of low-power,small bulk,high precision of sample can be provided and applied practically.
