Design of a Telemonitoring System for Data Acquisition of Livestock Environment

In order to realize the long-distance transmission of different environmental data from the field site to users, a universal project scheme of wireless telemonitoring system was designed to acclimate the characteristics of the observed places that are scattered and far away from a developed community, official sites. In this paper, integrated with modern information technologies such as sensors, communications, computer and networks, a remote environmental data acquisition system was developed that could be connected with most common sensors for agricultural environmental factors, such as air temperature and humidity, CO2, and some other harmful gases, etc. In the system, the kernel techniques of the system were to develop a seamless connection between wireless mobile network (GPRS/CDMA) and the Internet with TCP/IP software programming, the data from the remote observed sites were acquired in real time and transmitted to the central database servers. The data could be browsed, applied and downloaded by authorized users anytime and anywhere from the website with a PC, and also from the WAP site with a mobile phone. At present, it has been set up in some agricultural stations, horticultural greenhouses, methane-gas pools, as well as in animal shelters. It would be expected to extend in more livestock sites by further development both in hardware and software to meet convenient management and optimal control needs for livestock production
