【Abstract】 A design of the SCADA system used in gas dispatching network, including the data acquisition, communication and monitoring of the SCADA system, was described. The successful application of RTU that embedded “C” language editor was presented in details. The problem that T chart of the general RTU can’t communicate with substandard protocol was resolved. The ability of data acquisition of the SCADA system was improved. In the respect of communication, the mode of wireless communication was used like mobile telephone. The system became convenience and agility. Its reliability was enhanced at the same time.更多还原
