Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating load monitoring technology, and more specifically, to a heating terminal load monitoring architecture and intelligent monitoring system. Background Technology
[0002] Currently, in modern cities, centralized heating systems have become a key infrastructure for ensuring residents' comfortable lives. As the crucial node directly connecting the heating system and users, the load status of the heating terminal directly affects the overall operating efficiency of the heating system, the rationality of energy distribution, and the user's heating experience. Therefore, accurately grasping the load of the heating terminal is of paramount importance for heating companies to achieve refined heating scheduling, improve energy efficiency, reduce operating costs, and optimize user service quality.
[0003] In existing technologies, the load monitoring process for heating terminals generally relies on the pressure difference and temperature difference of the supply and return water pipelines. When the load of the heating terminal fluctuates, such as due to leakage, the pressure difference and temperature difference in the supply and return water pipelines will change accordingly, thereby achieving a high accuracy in load monitoring.
[0004] However, in practical applications, heating pipes are constantly exposed to varying temperatures, causing their inner diameter to deform due to thermal expansion and contraction. This change in pipe diameter directly leads to differences in fluid velocity within the pipe, which in turn affects the accuracy of pressure monitoring. Even if the actual load on the heating terminal remains unchanged, the deviation in pressure monitoring data caused solely by the thermal deformation of the pipe's inner diameter will ultimately result in inaccurate calculations of the heating terminal load based on pressure and temperature differences. This makes it difficult to accurately determine the actual heating demand of the heating terminal, leading to errors when adjusting heating parameters. Consequently, this results in unnecessary energy waste, negatively impacts the user experience, and hinders the stable and efficient use of energy. Utility Model Content

[0059] Example 1
[0060] like Figure 1As shown, this utility model embodiment provides a heating terminal load monitoring architecture and an intelligent monitoring system including the heating terminal load monitoring architecture. The heating terminal load monitoring architecture includes a supply and return water pipeline structure 1, a temperature monitoring structure 2, a temperature-compensated pressure measurement structure 3, a flow velocity monitoring structure 4, and a speed control valve structure 5. The temperature monitoring structure 2 and the temperature-compensated pressure measurement structure 3 work together to effectively implement the predetermined heating terminal load monitoring process based on the supply and return water pipeline structure 1. The temperature compensation pressure measurement characteristics of the temperature-compensated pressure measurement structure 3 can be used to improve its pressure measurement accuracy. Simultaneously, the flow velocity monitoring structure 4 and the speed control valve structure 5 can be used to effectively adjust the water flow velocity in the supply and return water pipeline structure 1 to be consistent with the position of the temperature-compensated pressure measurement structure 3, thereby further improving the pressure measurement accuracy of the temperature-compensated pressure measurement structure 3 and enhancing the overall accuracy of the heating terminal load monitoring. The specific settings are as follows:
[0061] Please refer to Figure 1 The water supply and return pipeline structure 1 includes a water supply pipe 11 and a water return pipe 12 that are circulated to the heating terminal, which serve as the basis for the load monitoring pipe of the heating terminal.
[0062] The temperature monitoring structure 2 includes a water supply temperature sensor 21 and a return water temperature sensor 22; wherein, the water supply temperature sensor 21 is fixedly mounted on the water supply pipe 11, and the return water temperature sensor 22 is fixedly mounted on the return water pipe 12, so as to monitor the water supply temperature and the return water temperature in real time by means of the cooperation of the water supply temperature sensor 21 and the return water temperature sensor 22 respectively.

This allows for real-time monitoring of the water supply pressure and return water pressure through the water supply pressure sensor 31 and the return water pressure sensor 32, respectively. At the same time, the temperature compensation pressure measurement characteristics of the water supply pressure sensor 31 and the return water pressure sensor 32 significantly reduce the influence of temperature on the measured pressure value, making the measured pressure value closer to the actual pressure value and effectively improving the accuracy of pressure measurement.
[0064] As a preferred embodiment, both the water supply pressure sensor 31 and the return water pressure sensor 32 have a temperature-compensated pressure measuring end and a non-temperature-compensated pressure measuring end, which are used to obtain the pressure values measured before and after temperature compensation, respectively, and can further deduce the temperature difference value based on the pressure sensor, thereby comparing it with the temperature difference value measured by the temperature sensor, and then jointly judging the degree of sensor attenuation.

This allows for real-time monitoring of the water supply velocity in the water supply pipe 11 corresponding to the position of the water supply pressure sensor 31 via the water supply velocity sensor 41, and simultaneously, real-time monitoring of the return water velocity in the return water pipe 12 corresponding to the position of the return water pressure sensor 32 via the return water velocity sensor 42.
[0066] The speed regulating valve body structure 5 includes a water supply speed regulating solenoid valve 51 and a return water speed regulating solenoid valve 52; wherein, the water supply speed regulating solenoid valve 51 is fixedly mounted on the water supply pipe body 11, and the water supply speed regulating solenoid valve 51 is located at a predetermined gap position upstream of the water supply speed sensor 41 along the water supply direction a; the return water speed regulating solenoid valve 52 is fixedly mounted on the return water pipe body 12, and the return water speed regulating solenoid valve 52 is located at a predetermined gap position upstream of the return water speed sensor 42 along the return water direction b; the predetermined gap range is set to 5mm to 50mm. m; is used to adjust the closing degree of the water supply speed regulating solenoid valve 51 and / or the return water speed regulating solenoid valve 52, so as to reduce the local inner cross-section of the water supply pipe body 11 and / or the return water pipe body 12, thereby increasing the local water flow velocity, and using the flow velocity recovery distance formed by the inertia and viscosity of the water, until the water flow velocity measured by the water supply speed sensor 41 and the return water speed sensor 42 tends to be consistent within the preset error range, so as to correct the pressure measurement error caused by the difference in the inner diameter and flow velocity of the pipe body of the water supply pressure sensor 31 and the return water pressure sensor 32, and further improve the pressure measurement accuracy.
[0067] Please continue to refer to this. Figure 1The intelligent monitoring system further includes an electrical control structure 6, which includes a power supply module, a control module, a control panel, and a touch screen connected by a circuit.
