Study on multi-environment factor monitoring system of the livestock breeding

To aim at the characteristics of livestock environment in china, a livestock breeding multienvironment factor monitoring system was studied. In this paper, the design thought and main function of the system were introduced, and design methods of system hardware and software described too. To begin with, the hardware part of monitoring system is build. The detection equipments of temperature and humidity, carbon dioxide, ammonia, hydrogen sulfide, as well as light monitoring equipment are included in this hardware part, and the former four sensors are assembled together in order to establish the breeding environment parameter perception concentrator. Then the technology project based on RS485 and Zigbee is respectively devised according to the different situations, and the solution of hardware anti-jamming is also proposed accordingly. Secondly, the software part of environmental monitoring system is structured. The data acquisition system based on C/S structure is mainly responsible for the information collection and storage tasks of environmental parameters, and the acquisition system is capable of 24 hours of work. Furthermore, this acquisition system also includes perfect management mechanism and reliable detection mechanism, as well as the alarm information is recorded and the management personnel is timely informed when environmental information exceeds alarm value in poultry housing. The monitoring system is featured by high precise, appropriate price, powerful function, which is suitable for most environments of barn farming in China and provides us with important reference for future environment control. © 2013 by IFSA.
