Description

Technical Field

[0001] The present invention relates to the technical field of pipeline heat theft prevention, and in particular to an anti-heat theft alarm system and method. Background Art

[0002] In the existing heat supply system, especially in the central heating system of residential areas, there is a common and thorny problem: user heat theft. Users usually steal heat by privately discharging hot water in radiators to increase the temperature of their own homes, or using water in heating pipes for activities such as laundry and cleaning. This behavior not only causes heat loss to the heating company and increases energy consumption, but may also affect the heating quality due to system water replenishment, and even cause equipment damage and safety hazards;

[0003] Traditional detection methods mainly rely on the continuous replenishment of water by the community heat exchange station replenishment pump to determine whether there is water theft in the community. Although this method can detect heat theft, it cannot accurately locate specific users. Therefore, operation and maintenance personnel need to check every building and every household. This is not only time-consuming and labor-intensive, but also inefficient, and it is difficult to stop heat theft in a timely and effective manner.

[0004] In addition, due to the different age of the community pipes, the blockage conditions are also different, resulting in different flow rates, making it impractical to set a unified flow rate alarm value. Therefore, a more accurate and intelligent method is needed to monitor and control the flow rate in order to detect and stop heat theft in a timely manner, reduce the economic losses of the heating company, and improve the efficiency and safety of the heating system. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

[0012] In order to solve the above technical problems, the present invention also provides an anti-heat theft alarm method including an anti-heat theft alarm system, and also includes: installing a manual valve on the heating pipe in the user's corridor, and connecting the locking valve behind the manual valve; connecting the flow rate device behind the locking valve to monitor the water flow rate in the pipe; setting the normal value and alarm value of the pipe flow rate, when the water flow rate in the pipe is higher than the alarm value, the pipe flow rate device triggers the alarm; after triggering the alarm, the flow rate device sends an alarm signal to the remote control room; after the remote control module receives the alarm signal, if the flow rate does not drop to the normal value within five minutes, the locking valve is remotely closed to prevent users from stealing heat; after the locking valve is closed, the operating personnel communicate with the user to confirm that it is normal, and then open the locking valve through the remote control module to continue heating.

[0013] As a preferred solution of the anti-theft heat alarm method described in the present invention, the flow velocity device converts the flow velocity into a 4-20mA signal and uploads the data to the cloud platform via an IC card.

[0014] As a preferred solution of the anti-heat theft alarm method described in the present invention, the remote control module receives flow rate data from the cloud platform through the two-network balance decision execution system, and issues an alarm when the flow rate is greater than a preset value.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Example 1, reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides an anti-theft heat alarm system, including a switch module for controlling the flow state of the liquid in the pipeline 104; a speed measurement module 103 for measuring the flow rate of the liquid in the pipeline 104; and a remote control module for receiving signal information sent by the speed measurement module 103, making a judgment based on the received information and sending a signal instruction to the switch module.

[0030] Specifically, the switch module includes a manual valve 101 and a locking valve 102 connected to the manual valve 101 , and both the manual valve 101 and the locking valve 102 are disposed in a pipeline 104 .

[0031] The velocity measurement module 103 includes a flow velocity device and a receiving device disposed on the flow velocity device.

[0032] Furthermore, the flow velocity device is disposed in the pipeline 104, and the receiving device is used to convert the flow velocity information of the flow velocity device into a signal and transmit it to the remote control module. The receiving device is also used to receive a signal instruction issued by the remote control module.

[0033] It should be noted that the anti-heat theft alarm system consists of three core parts: a switch module, a speed measurement module 103 and a remote control module, which work together to achieve real-time monitoring and control of the liquid flow state in the pipeline 104 to prevent and respond to heat theft.

[0034] The switch module is responsible for directly managing the flow of liquid in the pipeline 104, including a manual valve 101 and a shut-off valve 102 connected to the manual valve 101. Both valves are installed inside the pipeline 104. The manual valve 101 allows the operator to manually control the water flow, while the shut-off valve 102 automatically opens or closes according to the instructions of the remote control module to automatically respond to the detected abnormal flow rate.

[0035] The speed measurement module 103 is composed of a flow velocity device and a receiving device. The flow velocity device is installed in the pipeline 104 and is responsible for real-time monitoring of the flow velocity of the liquid in the pipeline 104. The receiving device converts the flow velocity information detected by the flow velocity device into a signal and transmits it to the remote control module, while receiving the signal command issued by the remote control module.

[0036] The remote control module is the decision-making center of the system. It receives the flow rate signal information from the speed measurement module 103 and makes judgments based on this information. If the flow rate exceeds the preset alarm value, the remote control module will instruct the locking valve 102 to close to prevent users from stealing heat. After the flow rate returns to normal, the remote control module can instruct the locking valve 102 to reopen to continue heating; in addition, the remote control module can also collect and analyze flow rate data through the cloud platform, dynamically adjust the alarm value, and automatically close the locking valve 102 in an emergency to reduce heat loss and protect user property.

[0037] Embodiment 2, the present invention also provides an anti-heat theft alarm method, including an anti-heat theft alarm system, and also includes: installing a manual valve 101 on the heating pipe 104 in the user's corridor, and connecting a locking valve 102 behind the manual valve 101; connecting a flow rate device behind the locking valve 102 to monitor the water flow rate in the pipe 104; setting a normal value and an alarm value of the flow rate of the pipe 104, when the flow rate of the water in the pipe 104 is higher than the alarm value, the flow rate device of the pipe 104 triggers an alarm; after triggering the alarm, the flow rate device sends an alarm signal to a remote control room; after the remote control module receives the alarm signal, if the flow rate does not drop to the normal value within five minutes, the locking valve 102 is remotely closed to prevent users from stealing heat; after the locking valve 102 is closed, the operating personnel communicate with the user to confirm that it is normal, and then open the locking valve 102 through the remote control module to continue heating.

[0038] Specifically, the flow velocity device converts the flow velocity into a 4-20mA signal and uploads the data to the cloud platform via an IC card.

[0039] Furthermore, the remote control module receives flow rate data from the cloud platform through the two-network balance decision execution system and issues an alarm when the flow rate is greater than a preset value.

[0040] Furthermore, an emergency action value is set on the locking valve 102. When the flow rate is greater than or equal to the emergency action value, the locking valve 102 is automatically closed to reduce heat loss and protect user property.

[0041] The rest of the structure is the same as that of Example 1.

[0042] Example 3, reference Figure 3 This embodiment is different from the above embodiments in that: the flow velocity device in the pipeline 104 is used to collect flow velocity data of different time periods; the collected flow velocity data is analyzed to determine the abnormal pattern of the flow velocity; based on the abnormal pattern, the alarm threshold is adjusted to improve the accuracy and response efficiency of the alarm system.

[0043] Specifically, each alarm event and corresponding user information are recorded through the remote control module; a statistical report of heat theft behavior is generated based on the recorded alarm events and user information; and the statistical report is used to optimize the management and maintenance of the heating system.

[0044] It should be noted that the present invention controls the water flow by installing a manual valve 101 and a locking valve 102 on the heating pipe 104 in the user's corridor, and the flow rate device connected to the locking valve 102 is responsible for monitoring the water flow rate in the pipe 104. When the flow rate exceeds the preset alarm value, the flow rate device will trigger an alarm and send the alarm signal to the remote control room. After the remote control module receives the signal, if the flow rate does not drop to the normal value within five minutes, the locking valve 102 will be automatically closed to prevent users from stealing heat. After the locking valve 102 is closed, the remote control module will reopen the locking valve 102 to continue heating only after communication and confirmation between the operator and the user.

[0045] The flow rate device converts the monitored flow rate into a 4-20mA signal and uploads it to the cloud platform via an IC card, so that the remote control module can receive the flow rate data in real time and issue an alarm when the flow rate exceeds the preset value. In addition, an emergency action value is set on the locking valve 102. When the flow rate reaches or exceeds this value, the locking valve 102 will automatically close to reduce heat loss and protect user property.

[0046] It is also able to collect flow rate data over different time periods, analyze abnormal flow rate patterns, and dynamically adjust alarm thresholds based on these patterns, thereby improving the accuracy and response efficiency of the alarm system.

[0047] The remote control module also records each alarm event and the corresponding user information, and generates statistical reports on heat theft, which are used to optimize the management and maintenance of the heating system. The entire system is designed to improve the safety and stability of the heat supply system through automation and intelligent means, reduce the workload of operation and maintenance personnel, and optimize the operation of the heating system through data-driven methods.

[0048] The rest of the structure is the same as that of Example 2.
