【Abstract】 Valves for gas pipeline leak detection and location system were analyzed based on acoustic signal. Combined with long-distance transmission GPRS /GSM network platform,system architecture model with positioning feedback was designed. The paper illustrates the composition and internal connection systems and designs the fixed device of the sensor. The leak hole acoustic signal frequency analysis table of different pipeline materials is used to design the running process block diagram of the system. Automated monitoring system proposed in the model plays an important significance for pipeline valve in leakage monitoring and positioning.更多还原
