Remote monitoring and controlling system of factory aquatic products breeding

The paper briefly introduces the constitution and the theory of operation of a computer-based remote monitoring and controlling system of factory aquatic products breeding with multi-environmental factors. This system is composed of many single-chip microcomputers used as fishponds controlling computers and two industrial control computers, one is used as remote monitoring computer and the other as field monitoring computer. It takes GPRS radio communication and Internet technology to communication between remote monitoring computer and field monitoring computer. The system can detect and control the breeding environmental factors such as temperature, content of dissolvent Oxygen, pH, water level, opacity and so on. It realizes the real-time monitoring and controlling the growth of the fish by computer image processing technology and it takes fault tree analysis technology to make the system reliability design. Once the system fault happen and the fish occur pathological changes and unwell, the system can give an alarm in time and inform the manager automatically by short messages.
