Design and Actualization of Leakage Early Warning and Location System of Gas Pipeline

To locate and pre-alarm timely and rightly is very important for controlling and reducing the people injuring and property loss of gas leakage. Based on the actual data, and taking the synchronism stimulation as method, the three color pre-alarm and location method has been explained. Combining the function and layout of system, the pre-alarm and location composite system has been established. Then, the stimulation subsystem, the data gather subsystem and the contrastive subsystem have been analyzed detailedly. The error of pre-alarm has been eliminated through contrasting by comparing the actual data and simulation data three times, and the precisions of pre-alarm and location has been advanced. With the characteristic of low cost and high precision, the actualization of the system has great application interesting in pre-alarm and location of gas leakage.
