Description

Technical Field

[0001] The present invention relates to the technical field of intelligent power supply control systems, and in particular to an intelligent power supply control system for industrial equipment. Background Art

[0002] With the advent of the Industrial 4.0 era, the industrial production process has undergone profound changes, and automation and intelligence have become the core driving force. Under this wave, enterprises’ demand for power supply is no longer just satisfied with the basic power supply function, but pursues a higher level of stability, reliability and intelligent management. In order to meet this challenge, the intelligent power control system of industrial equipment came into being. The integrated application of advanced technologies in this system has improved the continuity and stability of the power supply of industrial equipment, and has also improved production efficiency and safety, reduced maintenance costs, and laid a solid foundation for the transformation and upgrading of enterprises to intelligent manufacturing. Although the intelligent power control system of industrial equipment has achieved some results in improving the intelligence level of power supply, it still faces some challenges in practical application and urgently needs improvement. First, due to the remote environment of the factory, especially in areas prone to lightning, the existing system has insufficient protection capabilities when facing extreme weather such as lightning, which can easily cause damage to the power supply equipment, and then cause power outages, causing short-term industrial production obstacles and property losses; secondly, during the operation of industrial equipment, the load of the power supply equipment changes greatly, and there is a lack of real-time and comprehensive monitoring mechanism, making it difficult to detect and deal with overload conditions in a timely manner, increasing the risk of equipment failure. Summary of the invention

[0003] In order to solve the above problems, the present invention provides an intelligent power control system for industrial equipment, including an industrial equipment power data acquisition module, an industrial equipment power data processing module and an industrial equipment power data analysis module; The industrial equipment power supply data acquisition module obtains the atmospheric electric field value and the lightning echo signal through the atmospheric electric field meter and the radar respectively, obtains the real-time voltage data of the load through the Hall sensor, and obtains the real-time load current data by combining the Ohm's law formula; The industrial equipment power supply data processing module sets the atmospheric electric field value range of different levels of lightning weather, draws a two-dimensional coordinate curve graph of the atmospheric electric field value; processes the echo signal, generates a lightning image using GIS, calculates the mean value of the lightning safety image grid data, and draws a two-dimensional grid coordinate graph of the lightning image grid data; establishes a two-dimensional coordinate system, maps the current data collected by the sensor to the coordinate system, and obtains a load current data curve graph; The industrial equipment power supply data analysis module analyzes the atmospheric electric field value, GIS lightning image data, lightning image raster data and load current data, and obtains the forecast data of lightning activity within 24 hours, the spatial distribution of lightning occurrence and the interaction relationship with other geographical elements, the intensity change law of lightning activity and power overload conditions, and feeds back the abnormalities to the client.

[0004] Furthermore, the process of obtaining the atmospheric electric field value by the industrial equipment power supply data acquisition module includes: Based on the principle that a conductor generates induced charges in an electric field, the atmospheric electric field meter has a built-in high-precision sensor to measure the electric field strength of the surrounding environment in real time. The sensor consists of a stator and a movable plate. The stator is fixed and used to induce charges; the movable plate is grounded and driven to rotate by a motor to shield the stator. When the movable plate rotates, the stator is alternately exposed to the atmospheric electric field and shielded by the movable plate, generating an alternating electric signal. The larger the alternating electric signal, the greater the electric field strength. The built-in electric field data processing mechanism of the atmospheric electric field meter reads the atmospheric electric field value in real time.

[0005] Furthermore, the process of obtaining the lightning echo signal by the industrial equipment power supply data acquisition module includes: The radar emits electromagnetic waves in horizontal and vertical directions. The electromagnetic waves are scattered by the atmosphere and its suspended matter to form echo signals. The received echo signals are used to analyze the changes in the reflectivity, speed and polarization characteristics of the clouds. The radar receives the echo signals and collects lightning echo signals.

[0006] Furthermore, the process of obtaining real-time load current data by the industrial equipment power supply data acquisition module includes: The Hall sensor is placed in an industrial equipment environment. Based on the Hall effect principle, the current flowing through the two ends of the load changes, and the magnetic field generated by the current changes accordingly. The Hall sensor converts the change of the magnetic field into a change of voltage, and obtains the real-time voltage data of the two ends of the load. Through Ohm's law U=IR, the rated voltage of the industrial equipment 220V and the load voltage values ​​collected at each time are used to calculate the load current data under the rated voltage and the load current data at each time.

[0007] Furthermore, the process of obtaining the two-dimensional coordinate curve diagram of the atmospheric electric field value by the industrial equipment power supply data processing module includes: Lightning weather is divided into three levels according to the atmospheric electric field value: yellow warning, orange warning and red warning: yellow warning, orange warning and red warning respectively describe the lightning level occurring when the atmospheric electric field value is within 0~2kv, 2kv~4kv and 4kv~6kv; A two-dimensional coordinate system is established, the vertical axis is set as the atmospheric electric field value, the horizontal axis is set as time, and three lightning atmospheric electric field value ranges are set as 0~2kv, 2kv~4kv, and 4kv~6kv. The atmospheric electric field values ​​collected by the atmospheric electric field instrument at each moment are mapped to the two-dimensional coordinate system to form an irregular curve, and a two-dimensional coordinate curve graph of the atmospheric electric field value is obtained.

[0008] Furthermore, the process of obtaining the two-dimensional grid coordinate diagram of the thunder film image raster data by the industrial equipment power supply data processing module includes: According to the frequency characteristics of noise, filtering is used to filter out the noise contained in the echo signal received by the radar, and weaker lightning echo signals are collected multiple times to accumulate into normal lightning echo signals; GIS visualization is used to obtain lightning images in industrial monitoring areas. Argis software is used to calculate lightning image raster data. The raster data of lightning safety occurrence are summed and averaged to establish a two-dimensional grid coordinate system with the horizontal axis as time in months and the vertical axis as the lightning raster image data value. The mean of the raster image data of lightning safety occurrence is used to obtain the central two-dimensional rectangular grid coordinates filled with three horizontal lines. The mean of the real-time lightning raster image data is used to obtain the central two-dimensional rectangular grid coordinates filled with three oblique lines. The central two-dimensional rectangular coordinates of the mean of the real-time raster image data of lightning in the industrial area are mapped to the central two-dimensional rectangular coordinates of the mean of the raster image data of lightning safety occurrence to obtain the two-dimensional grid coordinate map of the lightning image raster data.

[0009] Furthermore, the process of obtaining the load current data curve graph by the industrial equipment power supply data processing module includes: The load current calculated using the rated voltage is set as the overload threshold of the industrial equipment power supply, and a two-dimensional coordinate system is established, with the vertical axis being the current value at each moment and the horizontal axis being time. The overload threshold is mapped to the coordinate system to form a parallel line parallel to the horizontal axis, marked with a red line; the actual load current value at each moment is then mapped to the coordinate system to form an irregular curve, marked with a black line, to obtain a load current data curve graph.

[0010] Furthermore, the industrial equipment power supply data analysis module analyzes the atmospheric electric field value two-dimensional coordinate curve graph, GIS thunder film image data, thunder film image grid data two-dimensional grid coordinate graph and load current data curve graph, and feeds back the abnormality to the client, including: S1. According to the distribution range of atmospheric electric field values ​​at different levels, the two-dimensional coordinate curve of atmospheric electric field values ​​is analyzed to determine the level of lightning weather. When the atmospheric electric field value reaches 0~2kv, a yellow lightning warning is triggered, indicating that there will be lightning activity in the next 6 hours; when the atmospheric electric field value reaches 2kv~4kv, an orange lightning warning is triggered, indicating that there is a high possibility of lightning activity in the next 2 hours, and a high possibility of lightning disasters; when the atmospheric electric field value reaches 4kv~6kv, a red lightning warning is triggered, indicating that there is a very high possibility of lightning activity in the next 2 hours, and a high possibility of lightning disasters; S2. Obtain the spatial distribution of lightning activity and its interaction with other geographical elements through GIS lightning image data, use GIS geographic information system platform to obtain the spatial distribution layer of lightning activity, intuitively display the geographical location and frequency of lightning activity, analyze the differences in lightning activity under different terrain conditions, the role of vegetation cover on lightning activity, and the effect of building layout on lightning protection. Use GIS lightning image raster data two-dimensional grid coordinate map to save and record lightning data from the past to the present. According to the distribution of three horizontal lines and three oblique lines in the grid, analyze the months corresponding to the number of grids exceeding the mean value of lightning grid image data, and predict the high-incidence season of lightning; S3. Analyze the current overload threshold of industrial equipment and its load current data curve to obtain the working status of the power supply at each moment. When the current overload threshold is not exceeded, the power supply system works normally; when the current overload threshold is exceeded, the power supply is overloaded; S4. The industrial equipment power supply data analysis module transmits the anomalies generated in the above analysis process to the client through wireless transmission, and the client takes measures to prevent lightning weather and deal with power overload.

[0011] The beneficial effects of the present invention are as follows: the present invention includes an intelligent power supply control system including an industrial equipment power supply data acquisition module, an industrial equipment power supply data processing module, and an industrial equipment power supply data analysis module. Compared with the intelligent power supply control system of traditional industrial equipment, the present invention implements stricter real-time monitoring of the working current of the power supply equipment and the lightning data of its surrounding environment, and promptly feeds back the abnormalities to the client, which takes measures to prevent lightning weather and deal with power overload, thereby solving the problems of power supply equipment damage caused by lightning weather and power supply interruption caused by overload of power supply equipment, and further promotes the intelligent power supply control system to supply the power necessary for the normal operation of industrial equipment and the troubleshooting of power supply equipment.
