The invention discloses a water supply equipment control system. The system comprises a plurality of water pumps, two frequency converters, a control unit, a switching group and a water pressure sensor; the control ends of the two frequency converters are connected to the control unit, and the output ends of the two frequency converters are connected to a node A; the input end of each water pump is connected with the switching group, and the switching group is respectively connected with the control unit and the node A; the control unit controls the operation of the switching group; the switching group controls conduction or cut-off of the input ends of the water pumps and the node A; and the water pressure sensor is connected with the control unit and used for detecting the water outlet pressure of a water using point. The invention also discloses a control method of the water supply equipment control system. The system has the advantages of realizing soft start and soft stop of the water pumps, eliminating the impact current when the water pumps are started, avoiding water hammer effect, stabilizing the water supply pressure, prolonging the service life and the reliability of the equipment and better ensuring the water using safety of a user.
