Abstract
This paper designed and realized a set of bullfrog breeding monitoring system based on Siemens S7-200 PLC, which integrates the stepping driver and stepping motor and uses the configuration king as the upper machine monitoring software. The system controls the running distance and speed for the automatic feeding management of bullfrog farm. Users can set the drinking water time, feeding time and feeding speed parameters according to the growth stage and demand of bullfrogs to ensure the accurate delivery of feed. The system has two automatic and manual operation modes, with strong flexibility, and realizes the functions of real-time monitoring, parameter setting, historical data query and alarm through the configuration king software. In addition, the system also integrates a variety of protection measures to ensure the safety of the operation, and effectively improve the level of automation and breeding efficiency of bullfrog breeding.
Key words: bullfrog breeding; PLC control; stepper motor; automatic feeding; configuration king monitoring
