Water supply hierarchical-control system
The invention provides a water supply hierarchical-control system. The water supply hierarchical-control system is composed of a water supply pump, an auxiliary control PLC controller, a main control PLC controller, an electric valve, a turbiditymeter, a residual chlorine analyzer, a pH meter, a water purification processor and an Ethernet switch; the water supply hierarchical-control system is characterized in that the water supply pump is connected with the PLC controller, the electric valve, the turbidity meter, the residual chlorine analyzer, the pH meter and the water purification processor are connected with the main control PLC controller, respectively, and the auxiliary control PLC controller and the main control PLC controller are connected with the Ethernet switch, respectively. The water supply hierarchical-control system has the beneficial effects that devices having direct a direct relation to water supply operation are connected to the auxiliary control PLC controller, while monitoring devices related to water supply are connected to the main control PLC controller, and therefore, the programming and control difficulty of the controller can be reduced and the operational reliability and safety of a water supply apparatus can be improved.
