| Abstract: | The paper mainly discusses how the SIEMENS PLC controls the remote-control fire self-motion monitor, and then it provides the problem - solving plan. That is, to use SIEMENS PLC to control alternative frequency conversion governor so as to change the running speed of the self -motion monitor, to use RS-485 to finish the communication between the rear console and the front self- motion monitor of the cable remote -control fire monitor, and to provide the main parameter, equipment, software technological process and A/D conversion for the system design. |
