[0037] Embodiments of the present application are described below in detail, examples of which are shown in the accompanying drawings, in which the same or similar elements or elements having the same or similar functions are denoted throughout by the same or similar reference numerals. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0038] A temperature measurement method, device, electronic device and storage medium according to embodiments of the present application are described below with reference to the accompanying drawings.

[0039] Figure 1 A flowchart of a temperature measurement method according to an embodiment of the present application is shown in FIG. 1, which includes the following steps. Figure 1

[0040] S101, obtaining configuration parameters of an overfire air layer of a boiler.

[0041] In implementation, in the process of combustion, an object in the furnace of the boiler needs to introduce overfire air to achieve the purpose of supplementing the air volume in the later stage of combustion in the boiler. Optionally, an overfire air nozzle can be arranged on the boiler wall of the boiler, and the introduction of overfire air in the furnace is realized by the gas flow input into the furnace through the overfire air nozzle.

[0042] As can be seen, the overfire air in the furnace of the boiler is composed of flowing gas flow. Since the overfire air is derived from the air outside the boiler, and there is a certain degree of temperature difference between the inside and outside of the boiler, the overfire air layer introduced from the outside of the boiler has a certain degree of influence on the temperature in the boiler.

[0043] Further, in order to avoid the influence of the overfire air layer on the temperature measurement in the boiler, the relevant parameter information of the overfire air layer can be obtained, so that the measurement position of the temperature in the boiler can avoid the influence range of the overfire air layer.

[0044] In an embodiment of the present application, the relevant parameter information of the overfire air layer can be obtained from the relevant hardware structure information of the boiler, and determined as the configuration parameters of the overfire air layer.

[0045] The configuration parameters can include the position of the overfire air layer in the boiler, the influence range of the overfire air layer on the temperature in the boiler, and other related information.

[0046] S102, determining a target cross section for temperature measurement of the boiler according to the configuration parameters.

[0047] ​In the embodiments of the present application, according to the configuration parameters of the overfire air layer, the position of the overfire air layer in the boiler and the related information of the influence range of the overfire air layer on the temperature inside the boiler can be determined.

[0048] In order to realize the temperature control inside the boiler, the temperature information of the overall space inside the boiler needs to be obtained, and therefore, the temperature information of the overall space inside the boiler can be obtained by measuring the temperature of the corresponding region of the cross section inside the boiler.

[0049] Optionally, in order to avoid the influence of the overfire air layer on the temperature measurement result inside the boiler, the cross section region for temperature measurement inside the boiler can be determined according to the configuration parameters of the overfire air layer.

[0050] Further, the cross section region can be determined as the target cross section for temperature measurement of the boiler.

[0051] In S103, the sound wave field of the target cross section is constructed, and the target temperature of the boiler corresponding to the target cross section is determined according to the sound wave signal in the sound wave field.

[0052] In the embodiments of the present application, in order to accurately and safely obtain the temperature information of the boiler in the region corresponding to the target cross section, the temperature measurement can be realized by a non-contact method.

[0053] Optionally, the temperature of the internal space of the boiler in the region corresponding to the target cross section can be measured by the sound wave signal.

[0054] Further, the corresponding sound wave field can be constructed for the target cross section, the corresponding equipment is arranged around the target cross section according to the set condition, so as to realize the construction of the sound wave field on the target cross section, and the temperature information of the internal space of the boiler in the region corresponding to the target cross section is obtained through the sound wave signal in the sound wave field.

[0055] Optionally, the related parameters of the sound wave signal in the sound wave field can be calculated based on a set algorithm, and the temperature of the internal space of the boiler in the region corresponding to the target cross section is obtained according to the calculation result.

[0056] Optionally, the related parameters of the sound wave signal in the sound wave field can be analyzed and processed based on a set data processing method, and the temperature of the internal space of the boiler in the region corresponding to the target cross section is obtained according to the analysis result.

[0057] Further, the temperature of the internal space of the boiler in the region corresponding to the target cross section can be determined as the target temperature corresponding to the target cross section.

[0058] The temperature measurement method provided in the application determines a target section for temperature measurement in the internal space of the boiler through configuration parameters of the overfire air layer of the boiler, and obtains the temperature of the internal space of the boiler on the region corresponding to the target section through the acoustic wave signal in the acoustic wave field constructed on the target section, as the target temperature of the target section. In the application, the setting position of the target section avoids the influence range of the overfire air layer, improves the accuracy of the internal temperature measurement of the boiler, and realizes the accurate temperature measurement under the premise of not changing the internal temperature distribution of the boiler through the non-contact temperature measurement of the acoustic wave signal, optimizes the temperature measurement method, and improves the safety and applicability of the temperature measurement.

[0059] In the above embodiments, the determination of the target section and the acquisition of the target temperature on the target section can be combined with the following Figure 2 It is further understood that Figure 2 The flowchart of the temperature measurement method of another embodiment of the application is shown in FIG. 2, which includes the following steps: Figure 2

[0060] S201, obtaining the first position information of the overfire air layer in the boiler from the configuration parameters.

[0061] In the process of determining the target section, in order to weaken the influence of the overfire air layer on the temperature measurement result, the temperature influence range corresponding to the overfire air layer can be determined according to the position of the overfire air layer in the boiler, so as to realize effective avoidance of the overfire air layer.

[0062] Optionally, the overfire air layer has corresponding configuration parameters, and the related information of the configuration parameters of the overfire air layer can be obtained from the hardware structure information of the boiler.

[0063] Further, the position of the overfire air layer in the boiler can be determined through the configuration parameters of the overfire air layer, and the related information of the position of the overfire air layer in the boiler is marked as the first position information.

[0064] The first position information can be the vertical distance between the overfire air layer and the plane where the bottom of the boiler is located, or other related information that can describe the specific position of the overfire air layer in the boiler, which is not limited here.

[0065] In some implementations, the related information of the position of the overfire air layer in the boiler can be directly obtained from the configuration parameters of the overfire air layer, so as to determine the first position information of the overfire air layer in the boiler.

[0066] In another implementation, the overfire air layer can be formed by the gas flow sprayed into the internal space of the boiler through the overfire air nozzle configured on the wall of the boiler, so the first position information of the overfire air layer in the boiler can be determined through the position information of the overfire air nozzle on the wall of the boiler. ​

[0067] Therefore, the first setting information of the overfire air nozzle on the boiler wall of the boiler can be obtained from the configuration parameters.

[0068] The first setting information can include setting position information of the overfire air nozzle on the boiler wall, and setting quantity information, etc.

[0069] Further, the first position information of the overfire air layer in the boiler is determined according to the first setting information.

[0070] Optionally, the vertical distance between the setting position of each overfire air nozzle and the surface where the bottom of the boiler is located can be obtained from the first setting information, and the difference between the maximum value and the minimum value of the obtained vertical distance data is obtained, and the position with the vertical distance between the setting position of each overfire air nozzle and the surface where the bottom of the boiler is located is determined as the position of the overfire air layer in the boiler, and the related information of the position is the first position information corresponding to the overfire air layer.

[0071] S202, the second position information of the measurement surface for measuring the temperature of the boiler is determined according to the first position information and the preset relative relationship.

[0072] In the implementation, the measurement surface for measuring the temperature of the internal space of the boiler has a preset relative position relationship with the overfire air layer, so the position information of the measurement surface in the internal space of the boiler can be determined according to the first position information corresponding to the overfire air layer and the preset relative position relationship.

[0073] Optionally, the setting direction and setting distance of the measurement surface relative to the overfire air layer and other related information can be determined from the preset relative relationship, and the corresponding position information of the measurement surface in the internal space of the boiler is determined and marked as the second position information.

[0074] For example, the preset relative relationship is set to include that the measurement surface is parallel to the overfire air layer and is set above the overfire air layer, and the vertical distance between the measurement surface and the overfire air layer is 5 meters. In the scenario where the vertical distance between the overfire air layer and the surface where the bottom of the internal space of the boiler is located is 20 meters, the measurement surface is set at a vertical distance of 25 meters from the surface where the bottom of the internal space of the boiler is located.

[0075] Further, the information can be determined as the second position information.

[0076] S203, the cross section of the boiler at the second position information is determined as the target cross section.

[0077] Further, after the second position information of the measurement surface for measuring the temperature of the internal space of the boiler is determined, the corresponding area of the furnace of the boiler at the second position information can be obtained.

[0078] The second position information may be continuous position information along the inner wall of the boiler. Therefore, the cross section of the furnace of the boiler corresponding to the second position information may be used as the measurement surface and determined as the target cross section.

[0079] S204 , dividing the target section into regions and obtaining target sub-sections after the target section is divided.

[0080] In implementation, there may be differences in the corresponding temperatures of different areas inside the boiler. Therefore, in order to obtain accurate temperature information of the boiler's internal space and to achieve temperature control of the boiler's internal space, the target cross-section can be divided into regions.

[0081] Optionally, the target cross section may be divided into regions according to the number of burners arranged on the inner wall of the boiler, and the sub-regions obtained after the division may be determined as target sub-sections of the target cross section.

[0082] like Figure 3 As shown, the front wall and the rear wall of the boiler furnace are respectively provided with 18 burners. Figure 3 The target section shown is set parallel to the surface where the bottom of the boiler is located. Then, a cutting line between the front wall and the rear wall can be constructed in a direction perpendicular to the plane where the front wall or the rear wall of the furnace is located, and the target section can be divided into 18 areas.

[0083] Accordingly, in order to better control the flame direction and temperature in the furnace, a cutting line between the left wall and the right wall can be constructed in a direction perpendicular to the plane of the left or right wall of the furnace to divide the target section into three areas.

[0084] Furthermore, the target section is divided into 54 regions, and the 54 regions are used as target sub-sections of the target section.

[0085] S205: Obtain a set value for the number of acoustic wave paths on the target sub-section.

[0086] In order to achieve contactless measurement of the temperature on the target sub-section, a corresponding acoustic wave field can be constructed for the target sub-section, and the temperature of the corresponding area of ​​the target sub-section can be measured based on the acoustic wave signal in the acoustic wave field.

[0087] Since there is a certain correlation between the accuracy of temperature measurement and the number of acoustic wave signal transmission paths in the corresponding area, there is a set number requirement for the acoustic wave signal transmission paths in the acoustic wave field on the target sub-section.

[0088] Optionally, the set value of the number of acoustic wave paths on the target sub-section can be obtained based on the relevant accuracy requirements of temperature measurement, or based on the relevant experimental results of simulation experiments, which is not limited here.

[0089] S206, construct the sound wave field corresponding to the setting value, and acquire the target temperature on the target section according to the sound wave signals in the sound wave field.

[0090] In the embodiments of the present application, the corresponding sound wave transceiving elements can be arranged around the plane where the target section is located, so as to construct the corresponding sound wave field for the target section.

[0091] In some implementations, the number of sound wave transceiving elements and the arrangement positions can be acquired according to the number of sound wave signal propagation paths in the sound wave field on the target section, so as to construct the sound wave field on the target sub-section.

[0092] The second arrangement information of the sound wave transceiving elements on the boiler wall corresponding to the target section can be determined according to the setting value.

[0093] Optionally, the related calculation can be performed according to the setting algorithm, and the related arrangement information of the sound wave transceiving elements in the corresponding region of the target section on the boiler wall can be determined from the calculation result, and the arrangement information is determined as the second arrangement information of the sound wave transceiving elements on the boiler wall.

[0094] The second arrangement information can include the arrangement positions and the number of the sound wave transmitting elements in the sound wave transceiving elements, and the arrangement positions and the number of the sound wave receiving elements.

[0095] Further, the corresponding sound wave transceiving elements are arranged at the corresponding positions on the boiler wall according to the second arrangement information, so as to construct the sound wave field corresponding to the target section.

[0096] The sound wave signals are transmitted by the sound wave transmitting elements arranged at the corresponding positions, and the sound wave signals are received by the sound wave receiving elements arranged at the corresponding positions, so as to construct the sound wave field on the target section.

[0097] As shown in Figure 3 , if the number of sound wave propagation paths in the sound wave field corresponding to the target sub-section is set to be at least 5, it can be determined according to the setting value that 8 sound wave transmitting elements and 12 sound wave receiving elements need to be arranged on the boiler wall in the boiler, and the arrangement positions are as shown in Figure 3 , and then the sound wave field as shown in Figure 3 is constructed for the target section.

[0098] In some other implementations, there can be abandoned holes at the corresponding positions of the target section on the boiler wall in the boiler, and in this case, the sound wave transceiving elements can be arranged on the abandoned holes.

[0099] It should be noted that when the boiler is in operation, there may be combustion dust generated. After the acoustic transceiver element is arranged on the boiler, the combustion dust may adhere to the acoustic transceiver element, thereby affecting the performance of the acoustic transceiver element.

[0100] Therefore, the boiler wall of the boiler is configured with a purge pipeline. The purge pipeline can be arranged at a position away from the acoustic transceiver element by a set distance, such as Figure 3 The purge pipeline arranged at the corresponding position of the acoustic transceiver element in the periphery of the acoustic transceiver element achieves the purpose of cleaning the adhering matter of the acoustic transceiver element through the arrangement of the purge pipeline.

[0101] Further, in order to obtain the acoustic signals in the acoustic field, corresponding acoustic signal transmission equipment needs to be arranged at the corresponding arrangement position away from the acoustic transceiver element. The corresponding acoustic signal transmission cable can be arranged on the boiler wall of the boiler, such as Figure 3 So that the acoustic signals in the acoustic field on the target section can be transmitted to the set server, thereby realizing the temperature measurement on the target section.

[0102] Optionally, the restored temperature field on the target section can be obtained according to the acoustic signals, and the corresponding target temperature of the boiler on the target section can be obtained from the restored temperature field.

[0103] In the embodiment of the present application, the corresponding fly time can be calculated according to the waveform of the acoustic signals in the acoustic field on the target section, and the path average speed on the acoustic signal propagation path is obtained. Further, according to the relationship between the propagation speed of the acoustic signals in the corresponding medium in the internal space of the boiler and the temperature, the average temperature on the acoustic signal propagation path is determined.

[0104] Further, according to the set restoration algorithm and the above-mentioned obtained related parameter information, the temperature field of the target section is restored, and the restored temperature field of the target section is obtained.

[0105] In the implementation, the restored temperature field has related temperature information of the target section, so that the set temperature on the target section can be obtained from the related information of the restored temperature field, and the set temperature is determined as the target temperature of the boiler inside on the target section.

[0106] For example, the corresponding acoustic field can be constructed for the target section as shown in Figure 3 The temperature field of the target section in Figure 3 is restored according to the acoustic signals therein, and then the target temperature of the target section is obtained from the restored temperature field of the target section as shown in Figure 4 .

[0107] In the embodiments of the present application, in order to realize the sub-regional high-precision control of the temperature inside the boiler, after the target temperature is obtained, the regional temperature on the target sub-section can also be obtained from the target temperature on the target section.

[0108] Optionally, the target temperature on the target section can be subjected to data calculation of the setting algorithm, and according to the calculation result, the temperature on the target sub-section inside the boiler is determined as the regional temperature of the target sub-section.

[0109] Optionally, the relevant temperature information on the target sub-section can be extracted by screening from the relevant temperature information shown by the restored temperature field of the target section, so as to obtain the regional temperature of the target sub-section.

[0110] Wherein, the regional temperature on the target sub-section can be obtained as shown in Figure 5 .

[0111] The temperature measurement method provided in the present application determines the target section according to the first position information of the overfire air layer in the boiler, further divides the target section into corresponding target sub-sections, determines the setting information of the sound wave transceiving element according to the number setting value of the sound wave transmission path in the sound wave field on the target sub-section, and arranges the sound wave transceiving element at the set position to construct the sound wave field on the target section. Further, the target temperature on the target section is obtained according to the sound wave signal in the sound wave field, and correspondingly, the regional temperature on the target sub-section inside the boiler is obtained according to the target temperature of the target section. In the present application, the setting position of the target section avoids the influence range of the overfire air layer, improves the accuracy of the temperature measurement inside the boiler, divides the target section into sub-regions, realizes the acquisition of the temperature information of multiple regions inside the boiler, improves the temperature control precision inside the boiler, realizes the temperature measurement in a non-contact manner through the sound wave signal, realizes the accurate temperature measurement without changing the temperature distribution inside the boiler, optimizes the temperature measurement method, and improves the safety and applicability of the temperature measurement.

[0112] For better understanding of the above embodiments, the Figure 5 further understanding, Figure 5 the flowchart of the temperature measurement method of another embodiment of the present application is shown in Figure 6 , which comprises:

[0113] From the hardware parameter information of the boiler, the first setting information of the overfire air nozzle is obtained, and then the first position information of the overfire air layer in the boiler is determined. Further, according to the first position information of the overfire air layer and the preset relative condition, the target section at the second position information is determined.

[0114] The target section is regionally divided, a divided target sub-section is obtained, and second setting information corresponding to the acoustic transceiving element is determined according to a set value of the number of acoustic signal transmission paths in the acoustic field on the target sub-section. Further, the acoustic transceiving element is arranged on the boiler wall corresponding to the second position information of the target section to construct the acoustic field corresponding to the target section.

[0115] Further, the acoustic signal in the acoustic field is obtained according to the signal transmission cable corresponding to the acoustic transceiving element, the temperature field on the target section is restored, the target temperature of the boiler interior on the target section is obtained from the restored temperature field, and the regional temperature on the target sub-section is determined according to the target temperature of the target section.

[0130] The temperature measurement device proposed in this application uses the configuration parameters of the boiler's burnout air layer to determine a target cross-section within the boiler's interior for temperature measurement. Furthermore, the target cross-section is divided into regions to obtain corresponding target sub-cross-sections. Based on the set value for the number of acoustic wave transmission paths within the acoustic wave field of the target sub-section, the device determines the configuration information for acoustic wave transceivers and arranges the acoustic wave transceivers at the set positions to construct an acoustic wave field on the target cross-section.
