Description

Technical Field

[0001] The present invention relates to the technical field of temperature monitoring of heating pipelines, and in particular to a method and system for monitoring the temperature of a medium in a heating pipeline. Background Art

[0002] Cold regions require centralized heating in winter. To conserve energy and reduce pollution such as smoke and dust, most areas rely on centralized heating systems. A heating system consists of a heat source (such as a thermal power plant or centralized boiler room), a heating network, heat exchange stations, and heat users. The heat source provides thermal energy and transfers it to the heat exchange station via the heating network. The heat exchange station then transfers the heat to the heat user through the corresponding heating network. The heating network consists of a large number of connected heating pipes. Maintaining a stable temperature within these pipes is crucial when providing heat to residential users, therefore, monitoring the temperature of the medium within these pipes is essential.

[0003] At present, the medium temperature in the heating pipe, that is, the water temperature, is usually collected by a plug-in temperature collector. Considering that the medium temperature in the heating pipe needs to be collected for a long time and the platinum resistance thermometer has good long-term stability, in the current heating system, the plug-in temperature collector usually uses a platinum resistance thermometer to obtain the medium temperature in the heating pipe for a long time.

[0004] However, long-term use of platinum resistance thermometers can lead to measurement deviations, resulting in inaccurate temperature monitoring of heating pipes and adversely affecting the control of heat supply in the heating system. Because the intubation-type platinum resistance thermometers used are expensive and complex to replace, when temperature deviations occur, the thermometers are typically not directly replaced. Instead, the measured medium temperature is corrected. Prior art methods primarily rely on manual field temperature measurements to calibrate the measured data from platinum resistance thermometers. However, this calibration method requires significant manpower and resources. When a large number of platinum resistance thermometers are installed in a heating pipe, manual calibration is inefficient and subject to human error. Summary of the Invention

[0005] In order to address the deficiencies of the above-mentioned prior art, the present invention provides a method and system for monitoring the temperature of the medium in the heating pipe. In view of the problems that the existing use of an intubation-type platinum resistance thermometer to measure the medium temperature in the heating pipe for a long time is inaccurate, which in turn affects temperature monitoring, and the existing temperature correction scheme is inefficient and wastes manpower and material resources, on the basis of using an intubation-type platinum resistance thermometer to measure the medium temperature in the heating pipe, a patch thermometer is added to the wall of the heating pipe corresponding to the platinum resistance thermometer, and the temperature correction is performed using the temperature measured by the patch thermometer, replacing the manual correction scheme, thereby achieving more efficient and accurate measurement of the medium temperature in the heating pipe, ensuring the accuracy of temperature monitoring, and ensuring stable heating for users in residential areas.

[0013] According to a further technical solution, the step of determining whether the first temperature change curve and the second temperature change curve are reasonable includes:

[0014] Based on the obtained temperature change curve, the temperature deviation between the maximum temperature value and the minimum temperature value in the temperature change curve is obtained. If the temperature deviation is greater than the preset deviation value, the obtained temperature change curve is determined to be unreasonable; otherwise, the obtained temperature change curve is determined to be reasonable.

[0015] Further technical solutions also include:

[0016] Based on the obtained first temperature change curve and the second temperature change curve, respectively, average the measured temperatures at each time point within the preset time period to obtain a first temperature average value and a second temperature average value;

[0017] The first temperature average value and the second temperature average value are compared. If the average deviation between the first temperature average value and the second temperature average value is greater than a preset average deviation, it is determined that the first temperature change curve is unreasonable.

[0018] In a further technical solution, the correction value is a correction value within a time period from the current correction time point to the next correction time point;

[0019] The sum of the temperature detected by the platinum resistance temperature sensor during the period from the current calibration time point to the next calibration time point and the calibration value is used as the medium temperature in the heating pipeline detected by the calibrated platinum resistance temperature sensor.

[0038] Example 1

[0039] In response to the problems that the existing use of intubation-type platinum resistance thermometers to measure the medium temperature in heating pipes for a long time is inaccurate, which in turn affects temperature monitoring, and the existing temperature correction scheme is inefficient and wastes manpower and material resources, this embodiment provides a method for monitoring the medium temperature in heating pipes. On the basis of using intubation-type platinum resistance thermometers to measure the medium temperature in the heating pipes, a patch thermometer is added to the heating pipe wall corresponding to the platinum resistance thermometer in the heating pipe. The temperature measured by the patch thermometer is used for temperature correction, replacing the manual correction scheme. Temperature monitoring is performed based on the corrected medium temperature to ensure the accuracy of monitoring.

[0040] This embodiment provides a method for monitoring the temperature of a medium in a heating pipeline. Figure 1 As shown, the specific steps include:

[0041] Step S1, obtaining a first temperature change curve of a medium in the heating pipeline detected by a platinum resistance temperature sensor in the heating pipeline at a preset frequency within a preset time period;

[0042] Step S2: obtaining a second temperature change curve of the wall surface of the heating pipe detected by the patch temperature sensor at a preset frequency within a preset time period; the patch temperature sensor is arranged on the wall surface of the heating pipe corresponding to the position (i.e., the measuring point) of the platinum resistance temperature sensor;

[0043] Step S3: determining whether the first temperature change curve and the second temperature change curve are reasonable. If both are reasonable, calculating the temperature error at each time point within a preset time period based on the first temperature change curve and the second temperature change curve, averaging the temperature errors at each time point, and obtaining a correction value.

[0044] Step S4: Correcting the temperature measured by the platinum resistance temperature sensor obtained until the next calibration time point based on the correction value;

[0045] Step S5: Based on the temperature measured by the calibrated platinum resistance temperature sensor, the temperature of the medium in the heating pipeline is monitored in real time.

[0046] There are a large number of interconnected heating pipes in the heating pipe network. An inserted platinum resistance temperature sensor is used in each heating pipe to be measured to measure the temperature of the medium in the pipe. Although the platinum resistance temperature sensor has good long-term stability, it will still have certain measurement deviations after long-term use. Considering that the heating pipes are usually made of steel and iron structures, which have good thermal conductivity, and in order to further ensure the heating performance, the outer surface of the heating pipe is usually covered with an insulation layer, so that the temperature of the pipe wall is infinitely close to the temperature of the medium in the heating pipe. Therefore, in order to further correct the problem of temperature measurement errors caused by long-term use of the platinum resistance temperature sensor, this embodiment sets a patch temperature sensor on the wall of the heating pipe corresponding to the position of the platinum resistance temperature sensor. The patch temperature sensor is located outside the outer surface of the heating pipe and inside the insulation layer, and the patch temperature sensor is used to measure the wall temperature of the heating pipe at the same position. Since the chip temperature sensor is low in cost and easy to install on the wall of the heating pipe, and when the chip temperature sensor is abnormal or damaged, it can be simply replaced, more importantly, although the chip temperature sensor cannot measure temperature for a long time, it has the performance of accurately measuring temperature in a short time, and the accuracy of temperature measurement in a short time is high. Therefore, the chip temperature sensor is used to measure the wall temperature of the heating pipe at the same position (i.e., the same measuring point), and the measured temperature is used as the standard for calibrating the temperature measured by the platinum resistance temperature sensor. The measurement error of the platinum resistance temperature sensor is obtained to correct the measured temperature, thereby ensuring the normal and accurate temperature monitoring.

[0047] Therefore, in steps S1 and S2 above, at the current calibration time point, a first temperature change curve of the medium within the heating pipe, detected by the platinum resistance temperature sensor within the heating pipe at a preset frequency and within a preset time period, and a second temperature change curve of the wall surface of the heating pipe, detected by the patch temperature sensor at a preset frequency and within a preset time period, are obtained. Considering that patch temperature sensors are capable of accurately measuring temperatures over short periods of time, in this embodiment, a preset time period is used to ensure the accuracy of temperature measurements obtained using the patch temperature sensor. Furthermore, since temperature sensors typically measure temperature at a specific point in time, this embodiment also presets a corresponding frequency, measuring the temperature at each point in the preset time period at the preset frequency, thereby obtaining the corresponding temperature change curves.

[0048] In the above step S3, based on the acquisition of the first temperature change curve and the second temperature change curve, it is determined whether the acquired first temperature change curve and the second temperature change curve are reasonable, thereby determining whether the platinum resistance temperature sensor and the patch temperature sensor are operating normally. Under normal circumstances, temperature changes will not fluctuate over a large range in a short period of time. Therefore, when a large range of fluctuations occurs, it is considered that the temperature sensor is abnormal, and the temperature data collected is also abnormal. In this embodiment, based on the acquired temperature change curve, the temperature deviation between the maximum temperature value and the minimum temperature value in the temperature change curve is obtained. If the temperature deviation is greater than the preset deviation value, it is considered that the acquired temperature change curve is unreasonable, that is, the corresponding temperature sensor is abnormal. Otherwise, the corresponding temperature sensor is operating normally.

[0049] In addition, considering that the performance of platinum resistance temperature sensors is relatively stable under normal circumstances, this embodiment, in order to further detect whether the temperature measured by the patch temperature sensor is reasonable, also includes: based on the obtained first temperature change curve and the second temperature change curve, respectively calculating the average of the measured temperatures at each time point within a preset time period, obtaining the first temperature average value and the second temperature average value, and comparing the first temperature average value and the second temperature average value. If the average value deviation between the first temperature average value and the second temperature average value is greater than the preset average value deviation, it is considered that the first temperature change curve measurement is incorrect, that is, the patch temperature sensor is abnormal.

[0050] Furthermore, when it is detected that the chip temperature sensor is abnormal and the platinum resistance temperature sensor is also abnormal, an alarm is issued to remind the staff to check, repair or replace the chip temperature sensor and platinum resistance temperature sensor of the corresponding measuring point; at the same time, the temperature data of the measuring point is discarded until the repair is completed.

[0051] When it is detected that the chip temperature sensor is abnormal and the platinum resistance temperature sensor is normal, an alarm is issued to remind the staff to check, repair or replace the chip temperature sensor at the corresponding position; at the same time, the temperature data of the measuring point is discarded until the repair is completed.

[0052] When it is detected that the chip temperature sensor is normal but the platinum resistance temperature sensor is abnormal, an alarm is issued to remind the staff to check, repair or replace the platinum resistance temperature sensor at the corresponding position; at the same time, the temperature detected by the chip temperature sensor at the current calibration time point of the measuring point replaces the temperature detected by the platinum resistance temperature sensor during the period from the current calibration time point to the next calibration time point until the maintenance is completed.

[0053] When the chip temperature sensor and the platinum resistance temperature sensor are detected to be normal, that is, when the temperatures detected by the platinum resistance temperature sensor and the chip temperature sensor are both reasonable, the temperature error at each time point within a preset time period is calculated based on the first temperature change curve and the second temperature change curve, and the temperature errors at each time point are averaged to obtain a correction value. It should be noted that this correction value is the correction value for the period from the current correction time point to the next correction time point.

[0054] In step S4, the temperature measured by the platinum resistance temperature sensor until the next calibration time point is corrected based on the correction value. Specifically, the sum of the temperature measured by the platinum resistance temperature sensor from the current calibration time point to the next calibration time point and the correction value is used as the corrected temperature of the medium in the heating pipe measured by the platinum resistance temperature sensor.

[0055] Finally, in step S5, the temperature of the medium in the heating pipe is monitored in real time based on the temperature measured by the calibrated platinum resistance temperature sensor. Specifically, the temperature measured by the calibrated platinum resistance temperature sensor is compared with a preset temperature range. If the temperature measured by the calibrated platinum resistance temperature sensor is within the temperature range, the temperature of the medium in the heating pipe is considered normal. Otherwise, the temperature of the medium in the heating pipe is considered abnormal, and an alarm is issued to prompt personnel to conduct appropriate inspections and repairs.

[0056] Furthermore, the calibrated temperature measured by the platinum resistance temperature sensor is uploaded to a remote client, which displays the calibrated temperature measured by the platinum resistance temperature sensor in real time on a display. Simultaneously, an alarm message is uploaded to the remote client, which issues an alarm.

[0057] Furthermore, the real-time temperature data measured by the platinum resistance temperature sensor and the patch temperature sensor are stored for subsequent viewing and analysis by staff.

[0058] Furthermore, the real-time temperature data and deviation values ​​measured by the platinum resistance temperature sensor and the patch temperature sensor are uploaded to the remote client and displayed in real time on the display of the client.

[0059] Through the above scheme, on the basis of the existing technology, this embodiment adds a patch thermometer to the wall of the heating pipe at the corresponding measuring point, and uses the temperature measured by the patch thermometer to correct the temperature measured by the platinum resistance thermometer, replacing the manual correction scheme, thereby achieving more efficient and accurate medium temperature measurement in the heating pipe, ensuring the accuracy of temperature monitoring, and ensuring stable heating for users in residential areas. In addition, the patch temperature sensor is low in cost and easy to install, which greatly reduces the waste of manpower and material resources.
