Research on SCADA system for urban pipeline network based on wireless sensor network

摘要

Summary form only given. In order to measure urban pipeline network signal and transmit the data to the data center in real time, the construction method about Supervisory Control and Data Acquisition (SCADA) system for urban pipeline network is presented based on GPRS and wireless sensor network through researching the characteristics of wireless sensor network as well as Zigbee technology. The system consists of wireless sensor network, GPRS network and monitoring center, the core of sensor node is integrated chip CC2430 called RF-SOC, which achieved the single-chip solution to field data collection and wireless transmission. The network coordinator node consisting of AVR microcontroller, RF chips and GPRS communication module plays the role of the gateway in the system. Some approaches for ensuring the reliability of data communication are discussed and system performance is validated through experiments. Experiment results show that the SCADA system based on GPRS and wireless sensor network improves the real-time property, reliability and integrity of pipeline network data with increasing the sensor node density in the monitored region.
