Description

Technical Field

[0001] This invention belongs to the field of de-temperature and pressure reduction equipment and involves data analysis technology. Specifically, it is a dual-mode control box and its control system for de-temperature and pressure reduction actuators. Background Technology

[0002] A desuperheater / pressure reducer is a device that reduces high-temperature, high-pressure steam to low-pressure, low-temperature steam that can be used by customers. Taking the boiler superheater outlet as an example, the steam generated by the boiler passes through the superheater outlet to the turbine to do work. The turbine has a range requirement for the parameters of the incoming steam. If the steam parameters at the superheater outlet exceed the high limit required by the turbine, it will damage the turbine. Therefore, a desuperheater / pressure reducer must be used to reduce the parameters to within the applicable range.

[0003] Existing desuperheating and pressure reducing actuators cannot monitor parameters such as deformation and cracks in their pipelines during operation, which leads to certain safety hazards during operation. Furthermore, it is impossible to take targeted measures to handle abnormalities when the desuperheating and pressure reducing actuators malfunction.

[0004] To address the aforementioned technical problems, this application proposes a solution. Summary of the Invention

[0029] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] like Figure 1 As shown, the dual-mode control box and its control system for the de-icing and pressure-reducing actuator include a processor installed inside the programmable local control box. The damaged original control unit is removed, and a self-designed electric valve "programmable local control box" is installed. This box can meet the requirements of electric opening and closing and opening degree adjustment in local mode, as well as the requirements of programmable opening, programmable closing and programmable opening degree adjustment in central control mode. A self-made valve scale index is used, and a scale dial is made using a mechanical guide rod and an insulating plate to facilitate observation of the valve opening degree. The limit switches for the open and closed positions are modified so that the electric valve can automatically stop after reaching the position, whether in local or programmable mode. After the modification, the control box is installed separately from the valve body and steam pipeline, which reduces the damage of the ambient temperature to electrical components, ensures the safe and stable long-term operation of power generation, avoids unplanned equipment shutdowns, has high economic benefits, and effectively improves safety and environmental benefits.

[0032] The processor has communication connections with a deformation monitoring module, a crack monitoring module, an operational evaluation module, and a storage module.

[0033] The deformation monitoring module is used to monitor the deformation of the pipeline of the desuperheating and pressure reducing actuator. It generates a monitoring cycle and divides it into several monitoring periods. The pipeline of the desuperheating and pressure reducing actuator is marked as the monitoring object. Several monitoring points are set on the side of the monitoring object. Images are captured at the beginning and end of each monitoring period and marked as the front and rear images, respectively. The front and rear images are compared to obtain the distance between the same monitoring point in the front and rear images and marked as the deviation value of the monitoring point. The deviation values ​​of all monitoring points are summed and averaged to obtain the deformation coefficient of the monitoring object within the monitoring period. The deformation threshold is obtained through the storage module. The deformation coefficient is compared with the deformation threshold: if the deformation coefficient is less than the deformation threshold, the deformation state of the monitored object during the monitoring period is determined to meet the requirements; if the deformation coefficient is greater than or equal to the deformation threshold, the deformation state of the monitored object during the monitoring period is determined to not meet the requirements, a deformation warning signal is generated and sent to the processor, and the processor sends the deformation warning signal to the operation evaluation module after receiving the deformation warning signal; the deformation of the pipeline of the de-temperature and pressure reducing actuator is monitored, and the deformation state at the beginning and end of each monitoring period is compared in a periodic monitoring manner, so as to obtain the deformation coefficient by numerical calculation based on the deviation value of all monitoring points, and the deformation state of the monitored object during the monitoring period is fed back through the deformation coefficient.

[0034] The crack monitoring module is used to monitor cracks in the pipeline of the desuperheating and pressure reducing actuator. It enlarges the front and rear images into pixel-level images and performs grayscale transformations to obtain front and rear grayscale images. The module retrieves the crack and corrosion grayscale ranges. Pixels in the front grayscale image whose grayscale values ​​fall within either the crack or corrosion grayscale range are marked as front crack pixels. Pixels in the rear grayscale image whose grayscale values ​​fall within either the crack or corrosion grayscale range are marked as rear crack pixels. The ratio of the number of front crack pixels to the number of pixels in the front grayscale image is marked as the front crack coefficient. The ratio of the number of rear crack pixels to the number of pixels in the rear grayscale image is marked as the rear crack coefficient. The difference between the rear crack coefficient and the front crack coefficient is marked as the crack mark value. The system obtains the crack marking threshold through the storage module and compares the crack marking value with the crack marking threshold. If the crack marking value is less than the crack marking threshold, the crack status of the monitored object during the monitoring period is determined to meet the requirements. If the crack marking value is greater than or equal to the crack marking threshold, the crack status of the monitored object during the monitoring period is determined to not meet the requirements. A crack warning signal is generated and sent to the processor. After receiving the crack warning signal, the processor sends it to the operation evaluation module. Crack monitoring is performed on the pipeline of the de-cooling and depressurization actuator. The crack grid of the pipeline is counted using image processing technology. Then, the difference in the proportion of crack grids between the pre-image grayscale image and the post-image grayscale image is compared to obtain the crack marking value. The crack marking value is used to provide feedback on the crack status of the monitored object during the monitoring period.

[0035] The operation evaluation module is used to perform operation evaluation analysis on the pipeline of the desuperheating and pressure reducing actuator. When the operation evaluation module receives a deformation warning signal or a crack warning signal, it marks the corresponding monitoring period as the evaluation period and obtains the processing data CL, ambient temperature data HW, and lumped data JZ of the monitored object within the evaluation period. The processing data CL is the volume value of steam processed by the desuperheating and pressure reducing actuator within the evaluation period. The process of obtaining the ambient temperature data HW includes: obtaining the air temperature value of the external environment of the monitored object and marking it as the ambient temperature value, and marking the maximum value of the ambient temperature value within the evaluation period as the ambient temperature data HW. The process of obtaining the lumped data JZ includes: dividing the evaluation period into several sub-periods, obtaining the volume value of steam processed by the desuperheating and pressure reducing actuator in each sub-period and marking it as the processing value of the sub-period, and calculating the variance of the processing values ​​of all sub-periods within the evaluation period to obtain the lumped data JZ. The operation coefficient Y of the monitored object within the evaluation period is obtained by the formula YX=α1*CL+α2*HW+α3*JZ. X, where α1, α2, and α3 are proportionality coefficients, and α1 > α2 > α3 > 1; the operating threshold YXmax is obtained through the storage module, and the operating coefficient YX is compared with the operating threshold YXmax: if the operating coefficient YX is less than the operating threshold YXmax, a maintenance optimization signal is generated and sent to the processor. After receiving the maintenance optimization signal, the processor sends it to the mobile terminal of the management personnel; if the operating coefficient YX is greater than or equal to the operating threshold YXmax, an aging replacement signal is generated and sent to the processor. After receiving the aging replacement signal, the processor sends it to the mobile terminal of the management personnel; the operation of the desuperheating and pressure reducing actuator pipeline is evaluated. When the monitored object shows crack or deformation abnormalities, the operating coefficient is obtained by comprehensively analyzing parameters such as the steam processing capacity of the desuperheating and pressure reducing actuator, the operating environment temperature, and the concentration of steam processing. The treatment measures are marked according to the operating coefficient to improve the efficiency of abnormal handling.

[0036] Example 2

[0037] like Figure 2 As shown, the dual-mode control method for a de-icing and de-stressing actuator includes the following steps:

[0038] Step 1: Deformation monitoring of the pipeline of the de-temperature and pressure reducing actuator: Generate a monitoring cycle and divide the monitoring cycle into several monitoring periods. Mark the pipeline of the de-temperature and pressure reducing actuator as the monitoring object. Obtain the deformation coefficient of the monitoring object within the monitoring period. Determine whether the deformation state of the monitoring object within the monitoring period meets the requirements by using the deformation coefficient.

[0039] Step 2: Crack monitoring of the pipeline of the de-temperature and pressure reducing actuator: Enlarge the front and back images into pixel grid images and perform grayscale transformation to obtain front grayscale images and back grayscale images respectively. Process the front and back grayscale images to obtain crack mark values. Use the crack mark values ​​to determine whether the crack status of the monitored object meets the requirements during the monitoring period.

[0040] Step 3: Perform operational evaluation and analysis on the pipeline of the de-temperature and pressure reducing actuator: Obtain the processing data CL, ambient temperature data HW, and centralized data JZ of the monitored object during the evaluation period, and perform numerical calculations to obtain the operating coefficient YX of the monitored object during the evaluation period. Generate maintenance optimization signals or aging replacement signals through the operating coefficient YX and send them to the processor.

[0041] The dual-mode control box and its control system for desuperheating and pressure reducing actuators generate a monitoring cycle and divide it into several monitoring periods during operation. The pipes of the desuperheating and pressure reducing actuators are marked as monitoring objects. The deformation coefficient of the monitoring object within each monitoring period is obtained, and the deformation state of the monitoring object within the monitoring period is judged based on the deformation coefficient to determine whether it meets the requirements. The front and rear images are enlarged into pixel-level images and subjected to grayscale transformation to obtain front and rear grayscale images. The front and rear grayscale images are processed to obtain crack marking values, and the crack marking values ​​are used to determine whether the crack state of the monitoring object within the monitoring period meets the requirements. The processing data CL, ambient temperature data HW, and lumped data JZ of the monitoring object within the evaluation period are acquired and numerically calculated to obtain the operating coefficient YX of the monitoring object within the evaluation period. The operating coefficient YX is used to generate a maintenance optimization signal or an aging replacement signal and sent to the processor.

[0043] The above formulas are all derived from software simulation using a large amount of data, and are selected to be close to the actual values.

[0044] The size of the coefficient is a specific value obtained by quantifying each parameter to facilitate subsequent comparison. The size of the coefficient depends on the amount of sample data and the corresponding operating coefficient initially set by those skilled in the art for each set of sample data. As long as it does not affect the proportional relationship between the parameter and the quantified value, such as the operating coefficient being proportional to the value of the processed data.
