The Design Of Pig Body Temperature Monitoring System Based On WiFi And Cloud Platform

With the development of wireless sensor network technology,the rapid development of the Internet of Things industry,intelligent applications have penetrated into all aspects of people’s lives.In particular,the application of wireless communication network technology to daily body temperature monitoring of animal breeding has greatly improved the development of intelligent aquaculture.The traditional method of measuring the body temperature of pigs is mainly determined by rectal temperature measurement by measuring the temperature of the pig rectum using a mercury thermometer.In order to improve many safety hazards in traditional temperature measurement methods and improve the accuracy of temperature detection,this paper comprehensively analyzes the specific conditions and technical requirements of pig breeding,and desi gns an intelligent pig body temperature monitoring system.The system is developed based on the wireless communication module ESP8266 and the China Mobile OneNET IoT cloud platform.The ESP8266 chip is internally integrated with a 32-bit ARM core and 4M Flash memory to implement data acquisition and data forwarding.The ESP8266 can be used as both a communication module and a system master chip.In the design,the body temperature monitoring node of the pig mainly collects the temperature of the pig ear.Due to the activity characteristics of the pig in the farm,the nodes need to be assembled on the pig’s ear in real time during the monitoring process,and the monitoring node is required to have small volume and strong anti-interference ability.Therefore,the digital temperature sensor DS18B20 is directly connected to the wireless communication module ESP8266,which simplifies the structure of the node.At the same time,the NTC thermistor temperature acquisition circuit is designed to detect the rectal bod y temperature,and the rectal temperature which can accurately reflect the body temperature of the pig is obtained.China Mobile’s OneNET IoT cloud platform is used to complete the functions of receiving,storing and forwarding data.Design an OneNET-based web application to monitor the graphical display of data.At the same time,it also developed the APP mobile phone client corresponding to the OneNET IoT cloud platform.The mobile phone login can also perform data viewing and truly realize remote monitoring.When the temperature data exceeds the set normal body temperature threshold,the system automatically performs an audible and visual alarm to alert the user.The design realizes the functions of real-time monitoring,storage,curve drawing and abnormal alarm of the pig body temperature data,and can realize effective real-time monitoring of body temperature in the pig breeding industry,prevent diseases and improve the scientific and technological level of the intelligent aquaculture industry.
