The monitoring system is composed of a main rack, an extended rack, a process field bus for communication between the main rack and the extended rack, a switch connected with the main rack by an Ethernet network, and a touch screen being connected with the switch and being used for controlling the main rack. The main rack is equipped with a central controller and a control power supply; and the extended rack is provided with direct input cards, direct output cards, analog input cards, and communication modules for communication with a remote control system. The system has advantages of excellent model selection and configuration performances, high universality and reliability, and high expansibility. On the basis of keeping the field hand-operated function, the secure, reliable, and precise field monitoring and remote monitoring functions are added. Meanwhile, the washing number can be combined freely based on the number of backwashing filters. Therefore, the accident potential of the field manual operation can be eliminated and the production efficiency is improved; and because of the flexible extendibility, the system can adapt to production load and operation need changes.
