Description

Technical Field

[0001] The present invention relates to the technical field of anti-theft of heating systems, and in particular to a household user water supply anti-theft monitoring system and a detection method. Background Art

[0002] With the rapid development of cities, centralized heating systems, as the basic infrastructure of cities, are becoming larger and larger, and the systems are becoming more and more complex. The impact of failures on society is becoming increasingly greater, so the reliability requirements are also becoming higher and higher. Currently, the main problems of centralized heating in cities are as follows:

[0003] In existing heating systems, water theft or accidental leaks often occur in hot water pipes in corridors or users' homes. When these situations occur, staff need to check the pipeline lines door to door for gradual investigation. The solution is not only labor-intensive, but also has a long response cycle and cannot take timely operational measures. It is difficult to achieve the ideal timely and rapid response and resolution for many leaking pipes.

[0004] Therefore, the present invention provides a household water supply anti-theft monitoring system and detection method, which installs a water stop valve and flow direction sensor on the water supply and return pipes of each household, and installs a water immersion sensor in the user's home, which can simultaneously realize intelligent judgment, water supply on and off, alarm and other functions. Summary of the Invention

[0005] The present invention proposes a household water supply theft prevention monitoring and heating system, which includes a water supply pipe and a return pipe. The system also includes a flow direction sensor, a water stop valve, a server, a communication gateway, a power supply module, and a water immersion sensor. The power supply module supplies power to the entire system. The water supply pipe and the return pipe are respectively arranged in the user's home, and the water supply pipe is provided with a water supply valve and a flow direction sensor. The return pipe is provided with a return valve and a flow direction sensor. The flow direction sensor is provided with a communication gateway. The water immersion sensor is arranged in the user's home, the water immersion sensor is connected to the communication module, and the communication gateway exchanges data with the server.

[0006] The detection method of the water supply anti-theft monitoring heating system for household users includes the following detection steps:

[0007] 1) Ensure that there is no water leakage in the water supply pipe, return pipe and user's home, open the water supply valve and return valve on the water supply pipe and return pipe respectively, use the flow direction sensor to count the water flow direction and flow rate in the water supply pipe and return pipe respectively, and transmit the statistical data to the communication gateway and upload it to the server, and record the floating range value of the water flow direction and flow rate in the water supply pipe and return pipe respectively as the reference value;

[0008] 2) At regular intervals, the flow direction sensor detects the flow rate in the water supply and return pipes and sends it as feedback data to the communication gateway. The feedback data is compared with the recorded reference value. When the feedback data differs from the reference value, the communication gateway issues a command to control the opening and closing of the water supply and return valves. The flow direction sensor determines the direction of water flow in the pipes, and then determines whether the user's home is misappropriating heating water or experiencing water leakage.

[0009] 3) At the same time, the water sensor and water stop valve installed in the user's home are linked and controlled through the communication gateway. When a water leak occurs in the user's home, the water sensor sends an alarm signal to the communication gateway to control the opening and closing of the water supply valve and the return valve, and promptly notifies and pushes the user's home information to maintenance personnel for on-site inspection and repair.

[0010] Preferably, when the flow direction sensor detects that the flow rate of the water supply pipe is greater than the benchmark reference value, and the flow rate of the return pipe is less than the benchmark reference value, the leakage sensor detects the leakage and alarms, the communication gateway triggers the detection mechanism, and controls the closure of the water supply valve and the return valve at the same time. By detecting the dynamic state of water flowing in the water supply pipe and the return pipe through the flow direction sensor, it can be proved whether there is a pipe leak in the user's home, and the communication gateway promptly pushes the detection information to the relevant personnel to arrange maintenance services.

[0011] Preferably, when the flow direction sensor detects that the flow rate of the water supply pipe is greater than the benchmark reference value, and the flow rate of the return pipe is less than the benchmark reference value, and at the same time the leakage sensor detects that there is no alarm for leakage, the communication gateway triggers the detection mechanism, and the communication gateway controls to close any water supply valve and return valve, and the flow direction sensor detects that the water flow in the same direction in the supply pipe and the return pipe stops, and detects whether the heating water source is stolen in the user's home, and the communication gateway promptly pushes the detection information to the relevant maintenance personnel for inspection.

[0012] Preferably, when the communication gateway controls the water supply valve to close, if the flow direction sensor at one end of the water supply valve shows that the water flow stops, and the flow direction sensor at one end of the return valve keeps the water flowing, it can be detected that the user's home is in the state of water theft, and the communication gateway promptly pushes the detection information to the relevant maintenance personnel for inspection.

[0013] Preferably, when the communication gateway controls the return valve to close, if the flow direction sensor at one end of the water supply valve keeps the water flowing, and the flow direction sensor at one end of the return valve stops the water flow, it can be detected that the user's home is in the state of water theft, and the communication gateway promptly pushes the detection information to relevant maintenance personnel for inspection.

[0014] Preferably, if it is detected that the user's home is in a state of stealing the heating water source, the communication gateway controls the water supply valve and the return valve to close at the same time. If the flow direction sensor stops, it can be determined that the user's home is stealing the water source.

[0015] Preferably, a communication module is provided in the communication gateway, and the communication module is an NB-Iot communication module and / or a 433MHz transmission module and / or a Thread communication module.

[0016] Preferably, the server is provided with a device for storing the flow parameters obtained by the flow sensor sent by the communication gateway, and the server is provided with a built-in data analysis and judgment algorithm, which calculates, judges and analyzes the pipeline flow data information of a single user and / or the flow data information of several users in the entire building and / or the sensor data information of several users in the entire area.

[0017] The beneficial effects of the present invention are:

[0018] 1. The flow direction sensor collects data on the water flow direction and flow rate of each household's water supply and return pipes in real time, and transmits the detection data to the server over long distances through the communication gateway at fixed intervals. By adjusting the various on-off modes of the water stop valves on the supply and return pipes, the flow direction sensor is used to detect whether there is water flow, and combined with the water immersion sensor installed in the user's home, it can quickly and in real time determine whether there is water leakage or water theft in the user's home. The response cycle from diagnosis to confirmation is short, the detection rate is high, and the staff can conduct investigations at designated locations and respond to and resolve the problem promptly and quickly.

[0019] 2. If users misuse water or seepage occurs in indoor pipes, the water supply and return valves installed on the supply and return pipes can be closed to stop heating. At the same time, the water immersion sensor installed in the user's room will detect water leakage in time and notify relevant personnel to carry out maintenance in a timely manner;

[0020] 3. The long-distance Internet of Things transmission protocol adopted collects information through flow sensors and water immersion sensors, and makes logical judgments through the gateway, so as to accurately control and prevent the flow and on-off conditions of each user or the entire building, effectively solve the problem of uneven heating effect, and improve energy utilization and heating service quality.
