Intelligent Controlling System of Pig Growth Environment

The pig growth environment is one key factor which affects breeding economic efficiency, this paper has developed distributed automatic control system of pig house environment based on fieldbus, the system includes the networks of CAN bus and Intranet and GPRS, remote users access the system server through browser to monitor the on-site controlling units, in the growth environment, the controlling strategy is the greatest goal of the ratio of output and input, the system can present environmental regulation scheme according to growth environment information and growth information of live pigs and the status information of controlling equipments, the system uses genetic algorithms to search the optimal values of the goal setting, the experiments have shown the system is good.
