Abstract

An in-line detection system for finding the pipe explosion failure of water supply pipeline network is composed of the control center MTU which consists of computer, multi-channel transceiver, modem and data set, and the remote terminals (RTU) which consists of data set, modem, multi-channel transceiver, microprocessor, A / D converter, water pressure sensor, and flow sensor. An in-line detection program is stored in the memory of computer. Its advantages are easy detection and high correctness.

Description

technical field [0001] The invention belongs to the measurement category of tap water supply, and in particular relates to the detection of pipe burst faults in urban water supply pipe networks. Background technique [0002] At present, many urban water supply systems in my country have set up pipe network data acquisition systems, which automatically monitor the water pressure and flow of certain nodes in the pipe network, and use wireless methods to transmit water pressure and flow values ​​back to the control center in real time, so as to To monitor the working condition of the entire water supply system. However, due to the lack of an effective fault detection system and detection method, in the event of a sudden accident, such as a burst tube failure, it is impossible to timely and accurately locate the fault and understand the extent of the fault. Contents of the invention [0003] The object of the present ...
