Abstract

The invention provides a simulation test system and method for an integrated liquid supply control system. The simulation test system comprises a controller, a simulator and a test management server,wherein an interface function configuration module in the simulator configures a transmission interface according to test requirements; a sensor signal simulation module simulates a sensor signal according to test requirements; a signal acquisition module receives a feedback signal which is sent by the controller and generated according to the sensor signal through the transmission interface, andconverts the feedback signal into a control signal suitable for communication transmission; and the test management server obtains a test result according to whether the control signal is matched withthe test requirement or not. By the adoption of the scheme, a sensor signal simulation mode and a controller signal collection and analysis mode which better conform to field application and are higher in precision are selected, manual field testing and signal collection are replaced, rapid simulation for the control mode of the integrated liquid supply control system can be achieved, and the simulation test system is more attached to the actual operation condition of the integrated liquid supply control system.
