Example 1

The centralized heat supply pipe network is divided into a primary pipe network between a heat source plant and a heat exchange station, a secondary pipe network between the heat exchange station and a user unit, wherein a primary monitoring module is arranged on the primary pipe network at intervals of 2 kilometers, and a secondary monitoring module is arranged on the secondary pipe network at intervals of 1 kilometer; a pipe network between a user unit and a single hot user is set as a user terminal pipe network, and a user terminal monitoring module is installed at each terminal user; the monitoring point detection equipment is a semiconductor pressure sensor and an electromagnetic flow sensor, integrates the pressure sensor and the flow sensor, and is arranged on a special connecting pipe section with the length of 1 meter in advance. The monitoring modules on the primary pipe network are named as 1001,1002 and 1003 1001,1002,1003 …, the monitoring modules on the secondary pipe network are named as 2001,2002,2003 …, the monitoring modules on the user terminal pipe network are named as 3001, 3002 and 3003 …, and the numbering naming is beneficial to subsequent data processing and accurate and rapid fault point positioning.

The pipe network monitoring module records the pressure and flow data of the monitoring module once every 5 minutes, the data transmission and receiving module converts the pressure and flow data of the monitoring module into electric signals, and corresponding data are transmitted to the pipeline monitoring module through the pipe network monitoring point communication terminal and the wireless receiver. The communication terminal module adopts a 5G module, and 5G communication has the advantages of high speed, strong penetrating power, large communication capacity and the like. The monitoring point detection equipment is arranged on the pipeline and buried underground; soil can hinder data transmission of the data transmission receiving module, so the data transmission receiving module is installed on nearby equipment such as municipal lighting street lamps and the like, and a power supply is provided for the data transmission receiving module.

And after the pipeline monitoring module receives the data transmitted by the data transmission and receiving module, the data can be processed. Firstly, converting the electric signal of each monitoring module into pressure and flow data, then calling the pressure and flow data of the monitoring module stored in a database at the last time point, and comparing the pressure and flow data with the data; if the deviation between the current pressure or flow data and the pressure or flow data of the last time point exceeds 20%, the monitoring point is classified as a possible fault point, and the data are transmitted to an alarm module; and if the deviation of the pressure and flow data and the pressure and flow data at the last time point exceeds 20 percent simultaneously, the monitoring point is classified as a most possible fault point and is transmitted to the alarm module.

After the alarm module receives the data of the possible fault point and the maximum fault point of the pipeline monitoring module, the manual operation record is called from the database, and the monitoring data of the monitoring module fluctuates due to manual adjustment, so that the factor of manual adjustment needs to be eliminated firstly. After each manual adjustment, the pressure and flow data of each monitoring module fluctuate, a function is established between the amplitude of each manual adjustment and the pressure and flow fluctuation condition of the monitoring module in the database, and then the function relation is continuously optimized.

The method comprises the steps that after an alarm module receives a possible fault point and a maximum possible fault point, manual regulation records are called, if manual regulation records exist before four time units before data fluctuation of a monitoring module, an expected monitoring module data fluctuation range is calculated according to an established manual regulation and monitoring module data fluctuation function, if the possible fault point and the maximum possible fault point are in the fluctuation range, the monitoring module data are considered to normally fluctuate due to manual regulation, then 4 time units are continuously concerned about the possible fault point, 8 time units are continuously observed for the maximum possible fault point, whether data stop fluctuating and recover stably is observed, and if the data are reduced and gradually kept stable subsequently, the fault alert of the monitoring module is removed. If the fluctuation range of the possible fault point and the maximum possible fault point exceeds the data fluctuation range of the expected monitoring module, the maximum possible fault point is directly alarmed, the data of the next 2 time units of the possible fault point are monitored, and if the data gradually converge to the expected range, the monitoring point is disarmed.

If no manual regulation record exists before four time units before the data fluctuation of the monitoring module, the maximum possible fault point of the first-level and second-level user terminal monitoring modules and the possible fault point of the first-level and second-level monitoring modules are directly alarmed; continuously monitoring two time units for possible fault points of the secondary monitoring module and the user terminal monitoring module, and observing whether data fluctuation is converged or not; disarming the monitoring module if the data fluctuation converges to a normal level, the data fluctuation being likely due to manual operation of the subscriber unit and the single hot user; if the data continuous fluctuation does not converge, directly alarming.

The method comprises the steps of constructing an electronic map of the heat supply pipe network in advance, identifying the position and the identification of each monitoring module on the map, alarming by an alarm module after the monitoring modules break down, displaying the number and the position information of fault detection points, reminding workers to check the fault points, and eliminating pipeline faults or faults of detection equipment.

Storing data of each time unit of each monitoring module in a database, including possible fault points and maximum possible fault points for eliminating faults, recording the data of the monitoring modules, and optimizing a manual regulation data fluctuation expectation function; due to the fact that the user condition is complex, the condition of a user terminal pipe network is complex, the reduction of the pipeline flow and even the pipeline blockage caused by scaling easily occur, and the troubleshooting is difficult. Therefore, a data graph is established for the monitoring data of the user terminal monitoring module in the database, if the pressure or the flow rate of the user terminal monitoring module continuously rises or falls, although the fluctuation range of each time is not large, the reasonable pressure and flow rate threshold value is broken through finally, a worker is reminded that the pipe section where the monitoring point is located has great pipe blockage, small flow leakage or pipe deformation risk, and possible faults should be eliminated.
