[0062] Specifically, in the embodiment of the present application, for each starting control program, editing is performed in the dynamometer system controller, in addition to editing the "speed-time" curve, an intake valve opening and closing instruction is also added, which is transmitted to the main station controller in the form of an I / O signal. When a starting control program starts running, an opening valve instruction is sent to the main station PLC (the valve action given value in the program is 1), and when a starting control program ends running, a closing valve instruction is sent to the main station PLC (the valve action given value in the program is 0).
