Abstract: In order to solve problems existed in software test of SAP integrated pressure pumping system such as low accuracy of input signal simulation and inconvenient operation, few detection channels of output signal, long check time of point table parameters and complex wiring, a software test platform for SAP integrated pressure pumping system was designed. The upper computer management software controls module groups to simulate input signal and transmit it to controller. After the input signal is collected by the controller, point table parameters are changed and transmitted to the upper computer management software. According to the input signal, the controller executes corresponding logic judgment and outputs control signal, which is collected by the module group and transmitted to the upper computer management software. The upper computer management software judges test result automatically according to whether the control signal matches the input signal. The application of the test platform improves efficiency and accuracy of test.
