Description

Technical Field

[0001] The present invention relates to the technical field of ventilation control, and specifically provides a ventilation control method, system and storage medium for a power distribution cabinet. Background Art

[0002] A power distribution cabinet is an electrical device used for distributing and managing electric power, and is widely applied in places such as buildings, factories, infrastructure, data centers, etc. The main function of the power distribution cabinet is to receive, distribute and control the flow of electric power, so as to ensure the safe, stable and efficient operation of electrical equipment. The power distribution cabinet contains various electrical components and wires inside, and heat will be generated during operation. If effective ventilation control is not carried out, the temperature may rise beyond the safe operating range of the equipment, resulting in component damage, performance degradation or fire risk. The change of temperature and humidity will affect the performance and service life of electrical components. Through ventilation control, the internal environment of the power distribution cabinet can be kept stable, and faults caused by drastic changes in temperature and humidity can be avoided. Therefore, the ventilation control of the power distribution cabinet is of great significance in ensuring safety, extending the service life of equipment, saving energy consumption and ensuring continuous power supply.

[0003] At present, the working conditions and environmental factors of the power distribution cabinet often change, and the fixed-gear ventilation adjustment cannot adapt to different usage scenarios and requirements. The fixed adjustment cannot collect and analyze real-time data, which limits the evaluation and optimization of the ventilation effect. The decision-making process lacking data support affects the long-term management efficiency. The fixed-gear ventilation adjustment mode faces multiple challenges in the modern power system, and there is an urgent need to adopt a more flexible and intelligent control mechanism to improve the ventilation efficiency and reduce energy consumption, so as to enhance the safety of electrical equipment.

[0042] S1: Communicate and connect with sensors built in the distribution cabinet to monitor and collect the operation information of the distribution cabinet, and store the collected operation information of the distribution cabinet; specifically, the sensors built in the distribution cabinet include: temperature sensors, humidity sensors, air flow sensors, load sensors, and vibration sensors; the operation information of the distribution cabinet includes: temperature, humidity, air flow rate, ventilation intensity, electrical power consumption, and equipment vibration intensity; the specific collection steps are as follows:

[0043] Arrange multiple temperature sensors at different heights and positions inside the distribution cabinet to obtain comprehensive temperature distribution information, obtain the temperatures at different heights and positions inside the distribution cabinet corresponding to the collection time points, calculate their average values, obtain the average temperature at different heights and positions inside the distribution cabinet corresponding to the current collection time point, and use this average temperature as the temperature corresponding to each collection time point inside the distribution cabinet;

[0045] Arrange multiple air flow sensors at different heights and positions inside the distribution cabinet to obtain comprehensive air flow rate information, obtain the air flow rates at different heights and positions inside the distribution cabinet corresponding to the collection time points, calculate their average values, obtain the average air flow rate at different heights and positions inside the distribution cabinet corresponding to the current collection time point, and use this average air flow rate as the air flow rate corresponding to each collection time point inside the distribution cabinet;

[0046] Arrange multiple load sensors at the power inlets of key equipment inside the distribution cabinet to obtain comprehensive load information, obtain the electrical loads corresponding to the collection time points inside the distribution cabinet, calculate their average values, obtain the average electrical load corresponding to the current collection time point inside the distribution cabinet, and use this average electrical load as the electrical load corresponding to each collection time point inside the distribution cabinet;

[0047] By arranging multiple vibration sensors at key parts of key equipment (such as motors and fans) inside the power distribution cabinet, comprehensive vibration information is obtained to get the vibration intensity corresponding to the acquisition time point inside the power distribution cabinet, and its mean value is calculated to obtain the average vibration intensity corresponding to the current acquisition time point inside the power distribution cabinet, and this average vibration intensity is used as the vibration intensity corresponding to each acquisition time point inside the power distribution cabinet.

[0048] S2: Calculate and analyze the operation information of the power distribution cabinet to obtain the ventilation evaluation value of the power distribution cabinet and send it to step S3; specifically as follows:

[0049] Obtain the numerical value of the temperature inside the power distribution cabinet and mark it as Wij, where i = 1, 2, 3... I, I takes positive integer values, I represents the total number of power distribution cabinets, and i represents the serial number of any one power distribution cabinet; where j = 1, 2, 3... J, J takes positive integer values, J represents the total number of acquisition times, and j represents the serial number of any one acquisition time; set a temperature threshold, the temperature threshold is set as the maximum safe operating temperature and mark it as W 阈值 ; Obtain the relative humidity inside the power distribution cabinet and mark it as Dij, set a humidity threshold, the humidity threshold is set as the maximum safe operating humidity and mark the humidity threshold as D 阈值 ; Obtain the air flow rate inside the power distribution cabinet and mark it as Lij; obtain the power consumption of the electrical equipment inside the power distribution cabinet and mark it as Gij; set a power consumption threshold, the power consumption threshold is set as the rated power upper limit and mark it as G 阈值 ; Obtain the vibration intensity of the power distribution cabinet and mark it as Zij; set a vibration intensity threshold, the vibration intensity threshold is set as the maximum safe vibration intensity and mark it as Z 阈值 ;

[0050] Substitute the dimensionless numerical values of the temperature value Wij, the temperature threshold W 阈值 , the relative humidity value Dij, the humidity threshold D 阈值 , the air flow rate Lij, the electrical power consumption value Gij, the power consumption threshold G 阈值 , the vibration intensity value Zij and the vibration intensity threshold Z 阈值 into the set formula Yij = a1×f W (Wij, W 阈值 ) + a2×f D (Dij, D 阈值 ) + a3×f L (Lij) + a4×f G (Gij, G 阈值 ) + a5×f Z (Zij, Z 阈值)Calculate the ventilation evaluation value Yij of the power distribution cabinet, where a1, a2, a3, a4, and a5 are the set weight factors respectively; where f W 、f D 、f L 、f G and f Z represent the normalization functions of each parameter. The temperature function f W is specifically as follows: The humidity function f D is specifically as follows: The air flow rate function f L is specifically as follows: The power consumption function f G is specifically as follows: The vibration intensity function f Z is specifically as follows: It can be seen from the formula that when the temperature value is greater than the temperature threshold, the higher the temperature value, the less safe the working state of the power distribution cabinet indicates, and the greater the ventilation evaluation value of the power distribution cabinet; when the humidity value is greater than the humidity threshold, the greater the humidity value, the higher humidity will cause equipment condensation, corrosion and insulation performance degradation, thus increasing the risk of equipment failure, and the greater the ventilation evaluation value; the lower the air flow rate, the higher the ventilation evaluation value; when the electrical power consumption value is greater than the power consumption threshold, the greater the electrical power consumption value, the higher power consumption may cause overheating, equipment damage or system failure, and the greater the ventilation evaluation value; when the vibration intensity value is greater than the vibration intensity threshold, the greater the vibration intensity value, the greater the potential risk of the power distribution cabinet indicates, and the greater the ventilation evaluation value; Send the ventilation evaluation value to S3;

[0051] Through real-time data collection and multi-dimensional analysis, it is possible to better judge whether the working state of the power distribution cabinet is safe, thus reducing the damage risk of electrical equipment in the power distribution cabinet caused by overheating, overhumidity or excessive vibration, and ensuring its safe and stable operation; by monitoring power consumption and air flow rate and optimizing ventilation management, higher energy utilization efficiency may be achieved and energy consumption may be reduced; by dynamically calculating the ventilation evaluation value and performing classification management, refined ventilation control is achieved, the safety, reliability and maintenance efficiency of the equipment are improved, higher energy utilization efficiency is achieved, and energy consumption is reduced.

[0052] S3: Mark the ventilation state of the power distribution cabinet and match the ventilation intensity according to the marking result; the specific steps are as follows:

[0053] Step 1: Obtain the ventilation evaluation value Yij of the power distribution cabinet, and set a ventilation evaluation threshold range. Compare and analyze the ventilation evaluation value with the set ventilation evaluation value threshold range. When the ventilation evaluation value is less than the minimum value of the set ventilation evaluation value threshold range, it indicates that the ventilation state of the power distribution cabinet is normal and no ventilation regulation is required. When the ventilation evaluation value is within the set ventilation evaluation value threshold range, mark the power distribution cabinet as a power distribution cabinet to be ventilated intensively. When the ventilation evaluation value is greater than the maximum value of the set ventilation evaluation value threshold range, mark the power distribution cabinet as a power distribution cabinet with priority for intensive ventilation.

[0054] Step 2: Obtain the basic ventilation intensity of the power distribution cabinet as T 基础 , from which the ventilation intensity of the normally ventilated power distribution cabinet can be obtained as T 基础 ; Substitute the dimensionless values of the basic ventilation intensity value T 基础 and the ventilation evaluation value Yij into the set formula group to calculate the ventilation intensity value Tij of the power distribution cabinet, where b1 and b2 are the set weight factors respectively. It can be seen from the formula that the power distribution cabinets to be ventilated intensively and with priority for intensive ventilation correspond to different ventilation intensity values respectively, and the ventilation intensity value of the power distribution cabinet to be ventilated intensively is greater than the ventilation intensity value of the power distribution cabinet with priority for intensive ventilation.

[0055] Step 3: Set several intensity ranges, each intensity range corresponding to a wind force value. Compare and match the ventilation intensity value with all the set intensity ranges to obtain the corresponding wind force value, and regulate the ventilation of the power distribution cabinet according to the wind force value. After maintaining the ventilation regulation state for a fixed duration, return to the ventilation monitoring module to re-monitor and analyze to obtain the ventilation evaluation value, and update the ventilation evaluation value to Step 1.

[0056] Step 4: Repeat the above steps until the ventilation prediction value is less than the threshold. Count the number of cycles P from Step 1 to Step 3. Set a cycle number threshold. When the cycle number P is greater than the cycle number threshold and the ventilation prediction value is still greater than the maximum value of the ventilation prediction threshold range, mark this power distribution cabinet as a high-risk power distribution cabinet and send it to S4.

[0057] By dynamically monitoring and regulating the ventilation status of the power distribution cabinet, adjusting system parameters and ventilation strategies, the safe and stable operation of the equipment is ensured; by adaptively regulating the wind force, it is more flexible than traditional fixed wind force regulation, not only improving the ventilation effect and safety of the power distribution cabinet, but also having a positive impact on energy conservation and resource utilization; effective ventilation can extend the service life of electrical equipment and reduce failures and losses caused by environmental factors; setting up an early warning mechanism can issue an alarm in a timely manner when the ventilation status of the power distribution cabinet is abnormal, facilitating the rapid adoption of measures to prevent accidents, which not only helps to improve the reliability and safety of the power distribution system, but also provides a guarantee for enterprises to save costs, optimize resource allocation and enhance the ability to respond to emergencies.

N, N is a positive integer, N represents the total number of background maintenance personnel, and n represents the number of any one background maintenance personnel; obtain the location information of the high-risk power distribution cabinet, and obtain the current locations of each background maintenance personnel, calculate the distance difference between the location of the background maintenance personnel and the location of the high-risk power distribution cabinet to obtain the interval distance between each background maintenance personnel and the high-risk power distribution cabinet, and mark it as MRn;

[0060] Step 2: Obtain the personnel information of the background maintenance personnel to be maintained, where the personnel information includes: name, age, working years and number of maintenance times; mark the working years and number of maintenance times of the background maintenance personnel to be maintained as QRn and HRn respectively; substitute the dimensionless values of the interval distance MRn, the working years QRn and the number of maintenance times HRn of the maintenance personnel into the set formula Calculate the priority value KRn of the background maintenance personnel to be maintained, where b3, b4 and b5 are respectively set weight factors, and their magnitudes are custom-set, and e is the natural constant; it can be seen from the formula that the closer the distance between the maintenance personnel to be maintained and the high-risk power distribution cabinet (the smaller the interval distance), the larger the priority value of the background maintenance personnel; the closer the working years of the background maintenance personnel are to the set priority working years, the larger the priority value of the background maintenance personnel; the more maintenance times of the maintenance personnel to be maintained, the larger the priority value of the background maintenance personnel; it should be noted that the priority working years of the background maintenance personnel can be set by professionals in the industry according to needs;

[0061] Step 3: Mark the background maintenance personnel with the highest priority value as the maintenance personnel for this time, and send the maintenance instruction to the terminal of this maintenance personnel. After the maintenance personnel confirm the maintenance instruction, update the status of this maintenance personnel to the maintenance-in-progress status and remove it from the sequence of personnel to be maintained;

[0062] Step 4: Match and allocate the personnel to be maintained in sequence according to the ventilation estimated value of the high-risk power distribution cabinets, and repeat the above Steps 1 to 3 until the maintenance of all high-risk power distribution cabinets is completed; when a maintenance personnel completes the maintenance of a power distribution cabinet each time, increase the maintenance times of this maintenance personnel by one, update the working status of this maintenance personnel to the sequence of personnel to be maintained, and upload the maintenance information of this maintenance personnel to the background maintenance terminal; the maintenance information includes: staff information, maintenance duration, maintenance log, etc.;

[0063] Through rapid early warning and personnel matching, ensure that high-risk power distribution cabinets can be maintained in a timely manner, reducing the risk of equipment failures; through priority value calculation, reasonably allocate maintenance tasks, improve the work efficiency of maintenance personnel, and ensure that experienced personnel give priority to handling important problems; through dynamically updating the status and maintenance times of maintenance personnel, continuously optimize subsequent scheduling decisions; through maintenance logs and statistical data, provide a basis for future maintenance plans and resource allocation, enhancing the scientific nature of decision-making; timely maintenance of high-risk power distribution cabinets helps prevent accidents and ensure the safe operation of the power system.

[0071] Obtain the supervision data of the ventilation holes corresponding to the power distribution cabinet, where the supervision data includes the ventilation hole images and the corresponding collection time, and analyze the supervision data. The specific analysis process is as follows:

[0072] The vent image is divided into several areas, and the areas that are not analyzed are eliminated. The remaining areas are magnified several times to obtain the pixel grid image corresponding to the area. The color and brightness of each pixel grid corresponding to the pixel grid image are identified to obtain several preset colors, where each preset color corresponds to a grayscale value; the color corresponding to each pixel grid in the pixel grid image is matched with several preset colors to obtain the corresponding grayscale value, and all the matched grayscale values ​​are summed to obtain the total grayscale value corresponding to the area; the brightness corresponding to each pixel grid is matched with the standard brightness corresponding to the corresponding vent image acquisition time. If the brightness corresponding to the pixel grid is lower than the standard brightness, the brightness difference between the two is calculated. If the brightness difference is greater than the set brightness threshold, the brightness difference is marked as a dark change value; all the dark change values ​​of the area are summed to obtain the total dark change value; the total grayscale value of the area and the corresponding values ​​of the total dark change value are converted into straight line lengths according to a certain ratio. , a semicircle is constructed with the total gray value as the radius, and then a semicone is constructed with the total dark value as the height of the semicircle, the volume of the semicone is identified and the value of the volume is marked as the monitoring value of the area; the monitoring values ​​of all remaining areas are summed up to obtain the total monitoring value; when the total monitoring value is greater than the set monitoring threshold, a monitoring instruction is generated and sent to the vent cleaning device; the vent cleaning device includes a driving unit and a cleaning unit, the driving unit drives the cleaning unit to move on the corresponding vent of the distribution cabinet, the cleaning unit cleans the vent and blows the generated dust out of the distribution cabinet; when the vent cleaning device receives the monitoring instruction, the total monitoring value is converted into a cleaning time according to a certain ratio, wherein the larger the total monitoring value, the longer the corresponding cleaning time; then the vent cleaning device controls the driving unit to drive the cleaning unit to move along the preset path, and at the same time the cleaning unit cleans the vent and blows the generated dust out of the distribution cabinet; after cleaning, the vent cleaning device is reset.
