More Information
Summary:The invention discloses a pump valve linkage control system and method, and the method comprises the steps: transmitting a circuit breaker switching-on signal through a main station PLC, and judging that a water outlet valve unit needing to be switched on is a power frequency unit through the main station PLC; when the unit of the water outlet valve is a power frequency unit, the main station PLC issues a circuit breaker closing signal; after receiving the closing signal of the circuit breaker, the i < o > slave station sends a signal indicating that the opening degree of a water valve is 30%; the i < o > slave station detects circuit breaker closing and valve feedback signals in real time. Interlocking and interconnection are carried out through an electrical control loop, a related logic program is embedded in a PLC, cooperation between the water pump unit and a water outlet valve is enhanced, and one-key starting and stopping are achieved. And when abnormity occurs in the one-key starting and stopping proc
