Firstly, this article discusses the necessariness to research and design a real time wireless safety supervisory control system of the digital natural gas field. Subsequently, based on the deep research of the related techniques and theories, I have taken part in the design of the real time wireless supervisory control system for the digital natural gas field. This system involves data acquisition and safety truncation in locale, the communication plat module by means of the USSD wireless communication technique, data processing module and the data showing module and introducing in detail the subsystem's densign and realization of the natural gas safety infromaiton plat. Lastly, this article has come to the conclusion and points out the trends. |
