Visual one-key sequence control test method, device and system

The invention discloses a visual one-key sequence control test method, device and system. The method comprises the steps that a sequence control request is sent to a sequence control host through a simulation sequence control centralized control master station; simulating primary and secondary equipment and receiving a sequence control instruction returned by the sequence control host according to the sequence control request; displaying the state change of the sequence control instruction executed by the simulation primary and secondary equipment, and generating remote signaling and telemetering signals; sending the remote signaling and the telemetering signal to the sequence control host; and receiving and displaying a sequence control result returned by the sequence control host according to the remote signaling and the telemetering signal. According to the invention, closed-loop automatic testing of the sequence control host can be realized, manual testing is not needed any more, and the accuracy of accep
