Abstract

A system module applied to the machine controller for simulating a machine operation screen based on a non-invasive data-extraction system, is disclosed. An image capture device of the system module can receive an original operation screen outputted from the machine controller, and transmit the original operation screen to the non-invasive data-extraction system and a high-speed image process unit for extraction of the information shown on the operation screen. The software control system can extract the operational information of the machine controller in real time, to create a machine operation flow for generating a simulated machine operation screen which is then outputted to a screen of the machine controller. As a result, the site working staff can be provided with operational information associated with the machine in real time, for example, the operational information includes currently executed operation screen, position of mouse cursor and pop-up window detection result.
