The invention discloses a public heat supply network pipeline leakage sensing system based on Internet of Things. The system comprises flow meters, M-BUS processors, a GPRS network, a center server and a remote monitoring center. The flow meters are arranged in the heat supply pipe network entrance of each user and each residential district heat exchange station. The M-BUS processors are arrangedin each residential district and community. The flow meters are connected with the M-BUS processors through an M-BUS bus cable. Each M-BUS processor collects the data of a flow meter according to an M-BUS standard protocol, and sends the acquired data to the central server through the GPRS network. The central server processes the received data. The remote monitoring center remotely monitors the safe operation of the pipe network of each community according to the data processed by the central server, and views the operation status of all monitored pipe networks online. According to the invention, real-time remote monitoring is realized through data analysis and pre-warning threshold setting; the abnormal change of the flow at each monitoring point can be timely detected; and the leakage point of a pipeline is accurately located.
Description
technical field [0001] The present invention relates to the technical field of pipeline leakage perception, in particular to a system and method for detecting pipeline leakage in a heating network based on the Internet of Things. Background technique [0002] As one of the most important subsystems in the urban lifeline system, the heating pipe network system plays a decisive role in the stability of urban people's life. With the development of our society and the improvement of people's living standards, the urban heating pipe network has never been The speed of development is not only reflected in the increase in the penetration rate of heating network pipelines, but also in the gradual extension of the heating area from north to south, and the gradual expansion of the scope of heating network pipelines. Due to the long wiring of heating network pipelines and many pipeline components, with the increase of the scale of the heating network and the increase of the service lif...
