[0002] With the intelligent development of the power industry, higher requirements are put forward for the accuracy and reliability of the material level monitoring of the dust removal hopper. Currently, the digital quantity signals (such as high / low level alarms) are usually transmitted to the dust removal control room through control cables, and then are connected to the DCS (Distributed Control System) system after being converted by the PLC (Programmable Logic Controller) system. However, with the intelligent upgrade of the power plant, the digital quantity signals can only provide threshold alarms and cannot reflect the continuous change of the material level in the hopper in real time, resulting in the ash discharge control relying on empirical judgment, with low efficiency. Moreover, in practical applications, the types of ash materials always change, which easily leads to errors in the material level monitoring. Summary of the Invention

[0009] According to a second aspect of the present disclosure, there is provided a dust - removal ash - hopper material - level correction system, the system includes: At least one material - level meter; A data processing device, configured to determine a radiation reference value corresponding to the current target material type in the ash hopper when a correction trigger condition is met, the radiation reference value being capable of characterizing the radiation intensity of the ash hopper in the full - material state, and store the radiation reference value in each of the material - level meters; The material - level meter is configured to, in response to receiving a material - level monitoring request, obtain an actual detected value of the current radiation intensity of the ash hopper as a target detected value, and determine the material - level information of the ash hopper according to the radiation reference value and the target detected value.

[0010] Optionally, the system further includes a material - type corrector for receiving a correction request input by a user; The data processing device is further configured to, when the material - type corrector receives the correction request, obtain correction information input by the user and determine the correction information as the radiation reference value.

[0015] Other features and advantages of the present disclosure will be described in detail in the subsequent specific implementation part. Brief Description of the Drawings

[0016] The drawings are used to provide a further understanding of the present disclosure, and constitute a part of the specification. They are used to explain the present disclosure together with the following specific implementation manners, but do not constitute a limitation to the present disclosure. In the drawings: Figure 1 is a flowchart of a method for correcting the material level of a dust removal ash hopper provided according to an embodiment of the present disclosure; Figure 2 is a block diagram of a device for correcting the material level of a dust removal ash hopper provided according to an embodiment of the present disclosure; Figure 3 is an exemplary block diagram of a system for correcting the material level of a dust removal ash hopper provided according to an embodiment of the present disclosure; Figure 4 is a block diagram of an electronic device shown according to an exemplary embodiment. Detailed Description of the Invention

[0017] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present disclosure, and are not intended to limit the present disclosure.

[0018] It should be noted that all actions of obtaining signals, information or data in the present disclosure are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where the location is located and obtaining the authorization given by the owner of the corresponding device.

[0019] Figure 1 It is a flowchart of a method for correcting the material level of a dust removal hopper provided according to an embodiment of the present disclosure. The method provided by the present disclosure can be applied to the material level monitoring scenario of a dust removal hopper to correct and optimize the material level monitoring result in this scenario and improve the accuracy of material level monitoring. By way of example, a passive nuclear level gauge can be used in the present disclosure.

[0020] As Figure 1 shown, the method for correcting the material level of the dust removal hopper provided by the present disclosure may include steps 11 to 14.

[0021] In step 11, when the correction trigger condition is met, a radiation reference value corresponding to the current target material type in the hopper is determined.

[0022] Among them, the radiation reference value can represent the radiation intensity of the hopper in the full material state. The radiation intensity can be represented by the count value of a specific ray per unit time. For example, if a passive nuclear level gauge is used, the radiation intensity can be represented by the count value of γ rays per unit time. Correspondingly, the radiation reference value is the count value of γ rays per unit time when the hopper is in the full material state. By way of example, for the material type of coal gangue ash, the radiation intensity is generally in the range of 800 - 1000, and for the material type of ordinary coal ash, the radiation intensity is generally in the range of 300 - 600.

[0023] The full material state of the hopper can be set according to actual needs, and can be determined according to the maximum allowable height of the material in the hopper. When the material in the hopper reaches the maximum allowable height, it is considered that the hopper is in the full material state. The maximum allowable height can be set according to actual needs, for example, set to the highest height of the hopper, or lower than the highest height of the hopper.

[0024] In a possible implementation manner, meeting the correction trigger condition may include receiving a correction request input by the user. That is to say, when a correction request input by the user is received, it can be considered that the timing of correction is met, that is, the correction trigger condition is satisfied.

[0025] Optionally, in the application scenarios of the present disclosure, a material type corrector may be provided, which may provide a correction function that can be manually triggered by the user (for example, a function button that can be triggered, etc.). Thus, when the user triggers the correction function of the material type corrector through an operation, a corresponding correction request will be received. Therefore, it can be considered that the correction trigger condition is met.

[0026] Correspondingly, step 11 may include the following steps: When a correction request is received, obtain the correction information input by the user; Determine the correction information as the radiation reference value.

[0027] When the user inputs a correction request, the user may input correction information, which may carry the radiation reference value. Thus, the correction information input by the user can be directly determined as the radiation reference value.

[0028] This implementation mode is equivalent to the user manually inputting the radiation reference value for correction. For example, the user can input correction information through empirical data. For another example, after the user manually discharges ash and confirms the ash level, the user can observe the data change of the level gauge to obtain the correction information for input.

[0029] In another possible implementation mode, meeting the correction trigger condition may include detecting that the ash hopper is in a full material state. That is to say, when it is detected that the ash hopper is full of materials, it can be considered that the timing of correction is met, that is, the correction trigger condition is met.

[0030] Optionally, in the application scenarios of the present disclosure, a limiter may be set inside the gray scale, and the limiter may be set at the highest allowable height of the materials in the ash hopper. In this way, whenever the height of the materials in the ash hopper reaches the highest allowable height, the limiter will be triggered to send a signal. Therefore, the limiter can be used to detect whether the ash hopper is in a full material state.

[0031] In this implementation mode, step 11 may include the following steps: When it is detected that the ash hopper is in a full material state, obtain at least one actual detection value of the radiation intensity of the ash hopper when it is in the full material state as a reference value; Determine the radiation reference value according to at least one reference value.

[0032] Optionally, the material type corrector provided by the present disclosure may also collect the radiation intensity of the ash hopper when the ash hopper is in a full material state to obtain an actual detection value. The principle of collecting the radiation intensity is the same as that of the level gauge. For example, if a passive nuclear level gauge is used in the present disclosure, the material type corrector may collect the γ-ray count value per unit time.

[0033] Therefore, when the ash hopper is detected to be in a full material state by the limiter, the material type corrector can be triggered to collect the actual radiation intensity at the full material state, that is, the actual detection value, as the reference value.

[0034] Among them, when the ash hopper is detected to be in a full material state, the material type corrector can be triggered to collect periodically, obtaining multiple actual detection values, that is, obtaining multiple reference values. These reference values can be used as the radiation intensity reference when the ash hopper is in a full material state with the current target material. Exemplarily, the collection can be performed at a period of 2 s (seconds).

[0035] After obtaining at least one of the above reference values, the radiation reference value can be determined according to the at least one reference value. Optionally, the radiation reference value can be determined in the following manner: Among the at least one reference value, determine the target reference value that is greater than or equal to the radiation intensity threshold; Determine the average value of the target reference values as the radiation reference value.

[0036] Among them, the radiation intensity threshold can be determined according to actual requirements. For example, it is determined according to the minimum radiation intensity of the target material type to ensure that the reference value used in the correction is reasonable and avoid interference data.

[0037] In this way, the reference values greater than or equal to the radiation intensity threshold are screened as credible target reference values, and then the average value of the target reference values is determined as the radiation reference value, which can improve the correction accuracy.

[0038] It should be noted that the material type corrector can stop the collection work when the ash hopper is no longer in the full material state. Based on this, whenever the material type corrector collects an actual detection value, it can start timing and record the timing duration. When the timing duration reaches the preset duration and no new actual detection value is obtained, the collection of the actual detection value can be stopped, and the step of determining the radiation reference value according to at least one reference value can be started.

[0039] Exemplarily, the preset duration can be set to the duration of several collection cycles. For example, if the collection cycle is 2 s, the preset duration can be set to 6 s (3 collection cycles).

[0040] Through the above steps, the radiation reference value corresponding to the current target material type in the ash hopper can be determined.

[0041] In step 12, store the radiation reference value.

[0042] Optionally, after step 11, the radiation reference value that conforms to the current target material type can be determined, and this radiation reference value can be stored. Exemplarily, it can be stored in each level gauge used in the present disclosure.

[0043] Under normal circumstances, the level gauge calculates the height corresponding to the current actual radiation intensity based on the radiation reference value (corresponding to the full material height) and the current actual radiation intensity, that is, the current material level of the target material type in the ash hopper. For example, the difference between the actual radiation intensity and the radiation intensity when the ash hopper is empty, divided by the difference between the radiation reference value and the radiation intensity when the ash hopper is empty, can obtain the percentage of the current material level occupying the material level height when full, so as to calculate the current material level. Therefore, the high accuracy of the radiation reference value is beneficial to improving the measurement accuracy of the level gauge.

[0044] In step 13, in response to receiving a material level monitoring request, obtain the actual detection value of the current radiation intensity of the ash hopper as the target detection value.

[0045] In step 14, determine the material level information of the ash hopper according to the radiation reference value and the target detection value.

[0046] When a material level monitoring request is received, the actual detection value of the current radiation intensity of the ash hopper can be obtained as the target detection value. Furthermore, based on the target detection value and the stored radiation reference value, the material level information of the ash hopper can be determined. The determined material level information can be uploaded to the DCS system.

[0047] Through the above technical solution, when the correction trigger condition is met, the radiation reference value corresponding to the current target material type in the ash hopper is determined and stored to accurately record the radiation intensity in the full material state of the ash hopper, providing accurate data support for subsequent data processing. And when a material level monitoring request is received, by obtaining the actual detection value of the current radiation intensity of the ash hopper and combining the stored radiation reference value, the material level information of the ash hopper can be determined more accurately. Thus, by updating the radiation reference value in real time, the radiation reference value always corresponds to the actual material type in the ash hopper, effectively avoiding the measurement error problem caused by the change of the material type, and then ensuring the accuracy and reliability of the material level monitoring. And by storing the radiation reference value, a stable reference basis can be provided for subsequent material level monitoring, further improving the intelligent level and adaptability of the material level monitoring, which is beneficial to providing strong technical support for the efficient and safe operation of thermal power plants.

[0048] Figure 2 It is a block diagram of a dust ash hopper material level correction device provided according to an embodiment of the present disclosure. As Figure 2 shown, the device 20 includes: A first determination module 21, configured to determine a radiation reference value corresponding to the current target material type in the ash hopper when the correction trigger condition is met, and the radiation reference value can represent the radiation intensity of the ash hopper in the full material state; A storage module 22, configured to store the radiation reference value; An acquisition module 23, configured to acquire an actual detection value of the current radiation intensity of the ash hopper as a target detection value in response to receiving a material level monitoring request; A second determination module 24, configured to determine the material level information of the ash hopper according to the radiation reference value and the target detection value.

[0049] Optionally, the satisfaction of the correction trigger condition includes receiving a correction request input by a user; The first determination module 21 includes: A first acquisition sub-module, configured to acquire correction information input by a user when receiving the correction request; A first determination sub-module, configured to determine the correction information as the radiation reference value.

[0050] Optionally, the satisfaction of the correction trigger condition includes detecting that the ash hopper is in a full material state; The first determination module 21 includes: A second acquisition sub-module, configured to acquire at least one actual detection value of the radiation intensity of the ash hopper when the ash hopper is in the full material state as a reference value when detecting that the ash hopper is in the full material state; A second determination sub-module, configured to determine the radiation reference value according to the at least one reference value.

[0051] Optionally, the second determination sub-module includes: A third determination sub-module, configured to determine a target reference value greater than or equal to a radiation intensity threshold value among the at least one reference value; A fourth determination sub-module, configured to determine an average value of the target reference value as the radiation reference value.

[0052] Optionally, the radiation reference value is the count value of the gamma ray per unit time.

[0053] Regarding the device in the above embodiments, the specific manners in which each module performs operations have been described in detail in the embodiments related to the method, and will not be elaborated herein.

[0054] The present disclosure further provides a dust removal ash hopper material level correction system, and the system includes: At least one level gauge; A data processing device, configured to determine a radiation reference value corresponding to a current target material type in the ash hopper when a correction trigger condition is satisfied, where the radiation reference value can represent the radiation intensity of the ash hopper in a full material state, and store the radiation reference value in each level gauge; The level gauge is used to obtain the actual detection value of the current radiation intensity of the ash hopper in response to receiving a level monitoring request, use it as the target detection value, and determine the level information of the ash hopper according to the radiation reference value and the target detection value.

[0055] Exemplarily, a passive nuclear level gauge can be adopted in the present disclosure.

[0056] The radiation reference value can characterize the radiation intensity of the ash hopper in the full-load state. The radiation intensity can be characterized by the count value of specific rays per unit time. For example, if a passive nuclear level gauge is adopted, the radiation intensity can be characterized by the count value of γ rays per unit time. Correspondingly, the radiation reference value is the count value of γ rays per unit time of the ash hopper in the full-load state. Exemplarily, for the material type of coal gangue ash, the radiation intensity is generally in the range of 800-1000, and for the material type of ordinary coal ash, the radiation intensity is generally in the range of 300-600.

[0057] The full-load state of the ash hopper can be set according to actual requirements. It can be determined according to the maximum allowable height of the material in the ash hopper. When the material in the ash hopper reaches the maximum allowable height, it is considered that the ash hopper is in the full-load state. The maximum allowable height can be set according to actual requirements, such as set to the highest height of the ash hopper, or lower than the highest height of the ash hopper.

[0058] As Figure 3 shown, in a possible implementation manner, the dust removal ash hopper level correction system may further include a material type corrector for receiving a correction request input by the user; The data processing device is further configured to obtain the correction information input by the user and determine the correction information as the radiation reference value when the material type corrector receives the correction request.

[0059] That is to say, in the case of receiving the correction request input by the user, it can be considered that the correction timing is met, that is, the correction trigger condition is satisfied.

[0060] The material type corrector can be provided with a correction function that can be manually triggered by the user (for example, a function button that can be triggered, etc.). Thus, when the user triggers the correction function of the material type corrector through an operation, a corresponding correction request will be received, so it can be considered that the correction trigger condition is satisfied.

[0061] This method is equivalent to the user manually inputting the radiation reference value for correction. Exemplarily, the user can input correction information through empirical data. For another example, after the user manually discharges ash and confirms the ash level, the user can observe the data change of the level gauge to obtain correction information for input.

[0062] Among them, the data acquisition device can communicate with the material type corrector through wireless communication.

[0063] Optionally, as Figure 3 shown, the dust removal hopper material level correction system further includes a material type corrector and a limiter disposed inside the hopper; The limiter is used to detect whether the hopper is in a full material state; The material type corrector is used to collect the actual detected value of the radiation intensity of the hopper when the hopper is in a full material state; The data processing device is further configured to trigger the material type corrector to collect at least one actual detected value of the radiation intensity of the hopper when it is in a full material state as a reference value when the limiter detects that the hopper is in a full material state; The data processing device is further configured to determine a radiation reference value according to at least one reference value.

[0064] The limiter can be set at the highest allowable height of the material in the hopper. In this way, whenever the material height in the hopper reaches the highest allowable height, the limiter will be triggered to send a signal. Therefore, the limiter can be used to detect whether the hopper is in a full material state.

[0065] The limiter can trigger an alarm in the form of a digital quantity limit switch being closed when the material level in the hopper reaches the full material height, and at the same time trigger the power-on operation of the material type corrector.

[0066] The principle of the material type corrector for collecting radiation intensity is the same as that of the material level gauge. For example, if a passive nuclear material level gauge is used in the present disclosure, the material type corrector can collect the γ-ray count value per unit time.

[0067] Therefore, when it is detected that the hopper is in a full material state by the limiter, the material type corrector can be triggered to collect the actual radiation intensity of the gray scale when it is in a full material state, that is, the actual detected value, as a reference value.

[0068] Among them, when it is detected that the hopper is in a full material state, the material type corrector can be triggered to collect periodically to obtain multiple actual detected values, that is, multiple reference values are obtained. These reference values can be used as the radiation intensity reference when the hopper is in a full material state with the current target material. Exemplarily, the collection can be performed at a period of 2 s (seconds).

[0069] Optionally, the data processing device is further configured to determine a target reference value greater than or equal to the radiation intensity threshold among at least one reference value, and determine the average value of the target reference values as the radiation reference value.

[0070] Optionally, the data processing device is further configured to start timing whenever an actual detected value collected by the material type corrector is obtained, and determine the radiation reference value according to at least one reference value when the timing duration reaches a preset duration and no new actual detected value is obtained.

[0071] Optionally, the material type corrector can also be used to stop the acquisition when the ash hopper is no longer full.

[0072] Exemplarily, the preset duration can be set to the duration of several acquisition cycles. For example, if the acquisition cycle is 2 s, the preset duration can be set to 6 s (3 acquisition cycles).

[0073] Among them, the radiation intensity threshold can be determined according to actual requirements. For example, it is determined according to the minimum radiation intensity of the target material type to ensure that the reference value used for correction is reasonable and avoid interference data.

[0074] In this way, the reference values greater than or equal to the radiation intensity threshold are screened as credible target reference values, and then the average value of the target reference values is determined as the radiation reference value, which can improve the correction accuracy.

[0075] The data processing device can broadcast the radiation reference value to each level gauge by wireless communication to store the radiation reference value in each level gauge.

[0076] It should be noted that Figure 3 the implementation scenario with 4 level gauges shown in

[0077] is only an example and is not used to limit the present disclosure. Usually, the level gauge will calculate the height corresponding to the current actual radiation intensity, that is, the current material level of the target material type in the ash hopper, according to the radiation reference value (corresponding to the full material height) and the current actual radiation intensity. For example, the difference between the actual radiation intensity and the radiation intensity when the ash hopper is empty, divided by the difference between the radiation reference value and the radiation intensity when the ash hopper is empty, can obtain the percentage of the current material level in the material level height when full, so as to calculate the current material level. Therefore, the high accuracy of the radiation reference value is beneficial to improving the measurement accuracy of the level gauge.

[0078] When receiving the material level monitoring request, the actual detection value of the current radiation intensity of the ash hopper can be obtained as the target detection value. Furthermore, based on the target detection value and the stored radiation reference value, the material level information of the ash hopper can be determined. The determined material level information can be uploaded to the DCS system, intelligent power plant or industrial control computer, etc.

[0079] Optionally, the data processing device can be connected to the DCS through a twisted pair or optical cable to achieve communication with the DCS.

[0080] Optionally, the data processing device can be connected to the industrial control computer through a twisted pair or optical cable to achieve communication with the industrial control computer.

[0081] Optionally, the data processing device can be connected to the intelligent power plant through a network port to achieve communication with the intelligent power plant.

[0082] In the above manner, by updating the radiation reference value in real time, the radiation reference value always corresponds to the actual material type in the hopper, effectively avoiding the measurement error problem caused by the change of the material type, and then ensuring the accuracy and reliability of the material level monitoring. Moreover, by storing the radiation reference value, a stable reference basis can be provided for subsequent material level monitoring, further improving the intelligent level and adaptability of the material level monitoring, which is conducive to providing strong technical support for the efficient and safe operation of thermal power plants.
