Description

Technical Field

[0001] The present invention relates to the technical field of substation noise monitoring, and more specifically, to a real-time monitoring and multi-dimensional analysis system for substation noise. Background Art

[0002] In order to meet the high-speed development of China's economy, more and more urban substations are being built; at the same time, in recent years, there have been more and more domestic governance projects for substation noise in order to alleviate the environmental protection pressure brought by complaints and disputes caused by substation noise. Investigations have found that there are still some deficiencies in the governance of substation noise projects: the primary and secondary relationships of substation noise control objectives are not clear; there are biases in the understanding of standards; the governance plans are relatively rough, the simulation analysis is too simple, and the distribution of substation noise cannot be fully displayed, resulting in the phenomenon that the governance effect of the project is not good and the project cost is inflated. Currently, the means commonly used in substation project governance is still the sound insulation control technology. As the environment where the substation is located becomes more complex, the closer and higher the sensitive points are, the greater the governance difficulty. A simple sound barrier cannot complete the control of noise alone, and a complex combination of sound barriers is required to achieve the control effect. This will inevitably increase the difficulty of predicting the noise control effect.

[0003] For existing substation noise detection methods and systems disclosed in patents with application numbers CN201110110992.X and CN201911149412.0, the monitoring data at the monitoring points are directly approximated as the sound source data to calculate the noise value at the receiving point, ignoring the sound loss between the monitoring point and the noise source. The calculation results are inaccurate, the analysis is too simple, and at the same time, the identification analysis of background noise and emission noise and the historical playback of the identification analysis are not provided, and the specific impact of the emission noise in the environment cannot be confirmed.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0044] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0045] Next, refer to Figures 1 to 6 to describe the substation noise real-time monitoring and multi-dimensional analysis system provided according to some embodiments of the present invention.

[0046] Embodiment 1:

[0047] A substation noise real-time monitoring and multi-dimensional analysis system includes a modeling module, a data module, a calculation module and a display module. The modeling module is connected to the calculation module, the calculation module is connected to the display module, and the data module is respectively connected to the modeling module, the calculation module and the display module, wherein:

[0048] The modeling module is used to extract the basic data of the substation, set the scene type, establish the geometric model of the substation, design the position of the detection points according to the actual situation, establish the detection points, and associate the detection points with the sound sources to provide basic data for the calculation module and the display module;

[0049] Such as Figure 1As shown in the figure, the specific operation process of this embodiment is as follows: The modeling module first establishes a static model for substation noise calculation and the positions of monitoring points, associates the monitoring points with the sound source devices established in the static model. The calculation module first performs grid preprocessing on the static model, taking the midpoint of each grid as the receiving point of the entire grid. Therefore, the size of the grid determines the calculation accuracy, and the grid size can be selected according to the processing capacity and accuracy requirements. In this embodiment, the side length of the grid is 0.08m, and this grid accuracy can make full use of computer resources, and the calculation results are very close to the actual accurate values. The calculation module obtains monitoring data, updates the sound source information in real time, and performs real-time calculations on the basis of the static model that has undergone grid preprocessing. Finally, the display module completes dynamic display and static analysis display. The dynamic display module includes three-dimensional dynamic display and real-time curve display, and the static analysis display includes generating prediction reports, noise straight-line distribution analysis, noise plane contour line analysis, and optimization calculation parts.

[0050] The modeling module includes a static model establishment unit and a detection point design unit, where:

[0051] The static model establishment unit simulates the substation scene according to the substation basic data and creates a substation environmental noise calculation model;

[0052] The detection point design unit designs the positions of detection points according to the substation equipment installation situation and the substation basic data, sets the detection point position attributes, and associates the detection points with the sound source devices;

[0053] The substation basic data includes: the plan view of the substation and its surrounding environment, the position relationship parameters of the sound source devices, buildings, and off-station sensitive targets, the geometric parameters of the buildings, fences, and off-station sensitive targets within the substation, the spatial height parameters of the substation and off-station, the sound power zone level of the surrounding environment, etc.

[0054] One sound source device can be associated with multiple detection points, and one detection point can only be associated with one sound source device. The detection points include sound source detection points, data verification detection points, and sensitive target detection points, where:

[0055] The sound source detection points are arranged adjacent to the sound source devices and are used to obtain the original noise monitoring data of the sound source devices;

[0056] The data verification detection points are set at any point within the substation, and the measured data of these detection points are used to verify the calculated data of the sound sources;

[0057] The sensitive target detection points are arranged adjacent to the sensitive targets and are used to obtain the noise data at the positions of the sensitive targets in real time.

[0058] Such as Figure 2As shown in the figure, establish a detection point, set the detection point location attribute, and associate the detection point with the data module and the noise source. The modeling module needs to correctly configure the client and connect to the Internet to obtain the data source in the data module. If the data source is not associated, the detection point will not be able to obtain noise data. The noise source refers to the noise source in the scene modeling. After the detection point is associated with the noise source, the noise data of the noise source can be calculated based on the noise data obtained by the detection point and the position relationship between the detection point and the noise source. If a noise source is associated with multiple detection points, the noise value of the noise source will be averaged based on the noise values calculated from multiple detection points. If a noise source is associated with a detection point, the noise source cannot be deleted in the scene. It needs to be disassociated before it can be deleted to ensure the normal flow of data and avoid data storms.

[0059] Embodiment 2:

[0060] On the basis of the above embodiment, the data module is used to collect information data of the substation end, obtain detection point data, transmit data between modules, and uniformly manage the data transmitted from each module to the data module, so as to realize data upload and call;

[0061] The data module includes a collection terminal, a transmission unit and a database, wherein:

[0062] The acquisition terminal is set at the detection point to obtain the noise data at the detection point;

[0063] The transmission unit is respectively connected with the acquisition terminal, the modeling module, the calculation module and the display module for data transmission;

[0064] The database is used to store basic information of the substation, calculated noise data and substation noise distribution calculation results. The database is connected to the acquisition terminal, modeling module, calculation module and display module through the transmission unit.

[0065] The database includes an original data buffer and a calculation result buffer, wherein:

[0066] The raw data buffer is used to store the basic information of the substation and the noise data collected by the acquisition terminal, and provide the raw calculation data for the calculation module;

[0067] The calculation result buffer is used to store the substation noise distribution calculation results and provide calculation result storage for the calculation module.

[0068] like Figure 3As shown in the figure, the data module stores the call logic as follows: After the system starts, it reads the parameters, starts the control interface for function selection, selects to start the sampling thread, calculation thread, and data upload thread. At the same time, parameter settings can be made in the function selection section, and the parameters are read again through the parameter file. After the parameters are updated, sampling is started again. Data acquisition, result calculation, and data upload are carried out synchronously. The microphone is started to continuously collect noise until manually turned off. The collected data is transmitted to the raw data buffer. At the same time, the calculation module repeatedly reads the raw noise data from the raw data buffer and performs calculations, outputs the calculation results to the interface, and transmits the calculation results to the calculation result buffer. Meanwhile, the data stored in the calculation result buffer and the raw data buffer is uploaded to the server at regular intervals according to the parameter settings. Whether the data is uploaded successfully can be determined by the flashing of the red and green lights. Whether the upload is successful or not, the data upload for the next time period starts. Data acquisition, result calculation, and data upload are parallel, which can effectively improve the calculation efficiency. The calculation function is synchronized using the acquisition waiting time. The raw data and calculation data are independently partitioned to avoid the spread of the impact of partial data damage.

[0069] Embodiment 3:

[0070] Based on any of the above embodiments, the calculation module is used to calculate the substation noise distribution. According to the scene type, it dynamically obtains the monitoring data of the detection points, performs reverse calculations, and obtains the sound source data of the sound sources associated with the detection points. The sound source data includes the background noise of the detection points and the sound power level data at the sound sources obtained by using the reflection surface engineering method. And it uses the sound source data and scene information to perform full-scene noise distribution calculation and analysis;

[0071] The calculation module includes a grid preprocessing unit and a real-time calculation unit, where:

[0072] The grid preprocessing unit is connected to the modeling module, and performs grid processing on the three-dimensional space, obstacles, and diffraction paths in the substation calculation model. The side length of the cube generated by the grid can be adjusted according to the required accuracy;

[0073] The real-time calculation unit is connected to the grid preprocessing unit. On the substation calculation model after grid processing, it uses the reflection surface engineering method to calculate the sound power level of the noise source. The sound power level result of the noise source is the average value of the results obtained by reverse calculations at multiple detection points, and uses the detection points other than the detection points bound to the noise source for result verification. It uses the calculated sound source data to perform full-scene distribution calculation and analysis, and at the same time calculates the influence of the background noise on the detection point noise data.

[0074] Such as Figure 4As shown in the figure, the processing flow of the calculation module is as follows: obtain the detection point data from the server of the data module. If the data acquisition is unsuccessful, repeat the data acquisition step. After successful acquisition, determine whether the data has been updated. If not, repeat the data acquisition. When the data is updated, use the detection point data to inversely calculate the noise data of each sound source, and calculate the noise distribution of the prediction point / line / surface / space according to the preprocessing result of the three-dimensional space grid of the substation.

[0075] The specific method for inversely calculating the accurate data of the noise source according to the detection point monitoring data by using the reflection surface method is as follows:

[0076] Determine the reference body and calculate the characteristic sound source size;

[0077] Select the measurement surface shape and calculate the measurement surface area. The measurement surface envelopes the measured noise source and terminates at the reflection plane where the sound source is placed;

[0078] Calculate the continuous steady-state sound level with the same mean square sound pressure as the measured sound pressure during the measurement time;

[0079] Calculate the average time-averaged sound pressure level;

[0080] Perform background noise correction and environmental correction on the average time-averaged sound pressure levels measured at all microphone positions on the measurement surface, and calculate the average value;

[0081] Calculate the frequency-weighted and octave band sound power levels of the measured sound source;

[0082] Calculate the A-frequency weighted sound power level from the octave band data:

[0083]

[0084] In the formula, L Wk is the sound power level of the k-th 1 / 1 octave or 1 / 3 octave band; C k is the A-frequency weighting value, which can be queried according to the A-frequency weighting value look-up table; k min and k max are the values corresponding to the lowest and highest frequency bands of the center frequency within the measured frequency range respectively.

[0085] Example 4:

[0086] Based on any of the above embodiments, the display module performs real-time calculation and display according to the data obtained by the calculation module, constructs a three-dimensional scene roaming display model of the substation, generates a prediction point analysis report, and displays the noise distribution of the line and space.

[0087] The display module includes a dynamic display module and a static analysis display module, where:

[0088] The static analysis display module generates a prediction point analysis report based on the data obtained by the calculation module, displays the noise distribution in a straight line and in space, and provides noise identification analysis.

[0089] The dynamic display module performs real-time calculations based on the data obtained dynamically in real time, draws real-time noise curves, creates a 3D scene roaming display model of the substation, and displays the noise change and distribution in the form of an animation.

[0090] The identification analysis of the noise includes emission noise analysis, background noise analysis, measured noise analysis, and comparison with the noise standard limits.

[0091] The display module can retrieve the data stored in the data module and perform historical data playback display.

[0092] As Figure 5 shown, the noise identification analysis analyzes the composition of the noise at each moment through the horizontal comparison of the emission noise, background noise, measured noise, and the day-night standard limits of the regional noise. Among them, the measured noise is the actual measurement data of the detection point, and the measured noise is composed of the background noise and the emission noise. The background noise includes the sounds emitted by the natural environment such as wind sounds and insect chirping, and the emission noise is the actual impact of the noise source output by the calculation module on the detection point. Through the calculation and display of the environmental noise in this embodiment, the noise composition of the detection point is clearly displayed. By comparing with the day and night standard limits of the regional noise, the impact of the environmental noise is removed, and it is easy to judge whether the emission noise meets the standard, and flexible treatment can be carried out. In the figure, the two straight lines L1 and L2 are the day and night standard limits of the regional noise, and the three fluctuating curves S1, S2, and S3 are the measured noise, emission noise, and background noise respectively.

[0093] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
