| Abstract: | Rolling canvas is a new type of advertisement . In order to reach a good propaganda effect, 16 rolling canvases on 8 advertisement machines are controlled by one Programmable Logic Controller(PLC). It is required that the canvases operate synchronistically. In their cyclic movements, canvas pictures with same order occur at the same time. After displaying for a while, they change to the next order pictures. It is under the coordination of PLC control software that canvases eliminate differences caused by machinery transmission mechanism and move in step.The control system provides manual/automatic operation modes and other functions such as periodical open/close,hold during power off and trouble diagnosis. |
