The control module 120 may receive the component model information and the component position information, and after receiving the component model information and the component position information, may compare the component model information and the component position information with preset component model information and component position information. In the case of consistent contrast, a target test component may be determined; under the condition that the comparison is inconsistent, alarm prompt information can be sent out for prompting that the component information identified by the staff is not matched with the preset component information, so that the target test component is determined manually.
And the signal simulation module 130 is connected with the control module and is used for simulating generation of component input signals aiming at the target test component and acquiring component output signals corresponding to the component input signals.
In the embodiment of the present application, a signal simulation module 130 may be provided. By connecting the signal simulation module 130 with the control module 120, the control module 120 may determine a target test component according to the component model information and the component position information, and drive the signal simulation module 130 to simulate a generation component input signal according to the determined target test component. Illustratively, the signal range of the component input signal may be 0 to 20 milliamps, 1 to 5 volts, or 0 to 10 volts, depending on the component model information and the component position information. The signal simulation module 120 may input the component input signal to a specific component after simulating the component input signal, and collect a component output signal corresponding to the component input signal and output by the specific component. Illustratively, the signal range of the module output signal may be 0 to 20 milliamps, 1 to 5 volts, or 0 to 10 volts.
