Description

Technical Field

[0001] The present invention relates to the field of charging piles, and in particular to a filter cotton replacement method, equipment, device, storage medium and electronic equipment. Background Art

[0002] DC charging piles are outdoors for a long time, and most of them are air-cooled. Dust and pollutants in the air directly enter the charging piles, corroding the components and materials inside the charging piles and shortening the service life of the product.

[0003] Because of the air-cooled heat dissipation method, the air inlet of the charging pile uses a high-efficiency filter to prevent dust. In areas with moderate or above dust, the filter is easily blocked. When the filter is blocked, the internal temperature of the charging pile rises, which will affect the safety and life of the charging pile over time. Therefore, after-sales personnel are often required to frequently visit the site to replace and maintain the filter cotton, which not only increases the maintenance cost of the equipment but also shortens the service life of the product. However, the current solution can only make it more convenient for after-sales personnel to replace the filter cotton, but does not reduce the frequency of after-sales personnel going to the site. Therefore, how to reasonably increase the life of the charging pile while reducing the number of manual replacements has become a problem. Summary of the invention

[0059] Among them, the terminal 130 can communicate with the server 110, and the terminal 130 may include a first terminal and a second terminal. The first terminal is used for the staff to receive the information transmitted by the server, and the second terminal is used for the user to receive the information transmitted by the server.

[0060] Based on this, the present application provides a filter cotton replacement method, equipment, device, storage medium and electronic device. The present application is described in detail below in conjunction with the accompanying drawings.

[0061] See also Figure 2 , Figure 2 : is a flow chart of a filter cotton replacement method provided in an embodiment of the present application, the method is applied to a server of a charging pile control system, the charging pile control system also includes a target charging pile, the target charging pile includes an air inlet, an air outlet and a filter cotton replacement device, the air inlet is equipped with a filter cotton, and the filter cotton and the filter cotton replacement device are connected; Figure 2 As shown, the method comprises the following steps:

[0062] S210, obtaining filter cotton remaining information of the target charging pile, where the filter cotton remaining information includes a remaining amount.

[0063] The target charging pile is equipped with a filter cotton replacement device, which stores disposable filter cotton. When the filter cotton needs to be replaced, the filter cotton is taken from the disposable filter cotton for replacement. The filter cotton remaining amount information is used to indicate whether there is any remaining available filter cotton, which is represented by the filter cotton remaining amount information, that is, the filter cotton remaining amount information includes a remaining amount, and the filter cotton remaining amount information may also include no remaining amount.

[0064] Specifically, the remaining number of filter cottons can be obtained through the filter cotton replacement device, or through a specific sensor device. For example, it can be calculated based on the original number and the number of replacements, or it can be obtained by a sensor, or it can be determined comprehensively by the remaining replaceable number and other factors. The specific process of obtaining the remaining number of filter cottons is not limited here.

[0065] The remaining amount can be determined based on the number of filter cottons and the first wind speed difference after the last use. Specifically, when it is detected that the number of remaining replaceable filter cottons of the charging pile is 0, and the first wind speed difference of the currently used filter cotton has not been detected to have reached the preset second wind speed threshold during use, it is determined that the remaining amount of filter cotton at this time is remaining, wherein the second wind speed threshold may be greater than the wind speed threshold.

[0066] In a possible embodiment, obtaining filter cotton remaining information of a target charging pile includes:

[0067] 211. Obtain the remaining replaceable quantity in the filter cotton replacement device, where the remaining replaceable quantity is the stock of unused filter cotton except the currently used filter cotton;

[0068] 212. If the replaceable quantity reaches the replacement quantity threshold, obtain usage data of the currently used filter cotton, the usage data indicating whether the currently used filter cotton reaches the preset second wind speed threshold during use, the usage data including reaching and not reaching; if the usage data is reaching, the filter cotton remaining amount information is no remaining amount; if the usage data is not reaching, the filter cotton remaining amount information is remaining amount;

[0069] 213. If the replaceable quantity does not reach the replacement quantity threshold, the filter cotton remaining information is that there is a surplus.

[0070] S220: If the filter cotton remaining amount information indicates that there is a remaining amount, obtain a charging pile parameter set of the target charging pile, where the charging pile parameter set includes a first wind speed difference, and the first wind speed difference is determined based on the wind speeds of the air inlet and the air outlet.

[0071] If the server detects that the filter cotton remaining amount information is a remaining amount, the charging pile parameter set of the target charging pile is obtained, and the charging pile parameter set may include multiple types of data, specifically including a first wind speed difference, which is calculated and determined based on the obtained wind speeds of the air inlet and the air outlet. Specifically, the target charging pile also includes a wind speed sensor, and the wind speeds of the air inlet and the air outlet may be obtained by the sensor.

[0072] In a possible embodiment, the charging pile control system also includes a first terminal, and the first terminal is used for staff to receive information transmitted by the server, and the filter cotton remaining information includes no remaining. The method also includes: if the filter cotton remaining information is no remaining, sending replacement information to the first terminal to prompt the staff to update the filter cotton replacement equipment; displaying a suspension of use information on the target charging pile to prompt the user that the target charging pile is unavailable.

[0073] The charging pile control system also includes a first terminal, and the server of the charging pile control system can communicate with the first terminal. The first terminal is a terminal used by the staff, which can be a computer, mobile phone, tablet computer, electronic watch or other electronic device, which can receive information from the server and convey information to the staff. The above-mentioned replacement information can be in various ways such as push, pop-up window, system information, phone call, etc., and the method and content are not limited here.

[0074] Among them, the target charging pile may also have an operation screen, and the target charging pile may display the suspension information on the operation screen of the target charging pile. In some cases, the charging pile control system also includes a second terminal, and the second terminal is used for the user to receive information transmitted by the server. After the second terminal establishes a connection with the target charging pile, the suspension information may also be sent to the second terminal. Specifically, the connection may be established by scanning a QR code or the like. If the target charging pile has an operation screen and there is currently no user's second terminal connected to the target charging pile, the suspension information is only displayed on the operation screen. If the target charging pile does not have an operation screen, the suspension information is sent to the second terminal after the user's second terminal establishes a connection with the target charging pile.

[0075] For example, the user scans the QR code of the target charging pile through the second terminal, and the server has determined that the filter cotton remaining information is no remaining at this time, and then sends a suspension information to the second terminal to inform the user that the target charging pile is unavailable.

[0076] Among them, if the filter cotton remaining information of the charging pile is no remaining, it means that the current charging pile has no replaceable filter cotton. If the filter cotton is blocked during use, it may cause the filter cotton to be unable to be replaced and cause the temperature to be too high. The target charging pile will display suspended use and prompt the staff to update the filter cotton replacement equipment.

[0077] Among them, no remaining can be determined based on the number of filter cottons and the first wind speed difference after the previous use. Specifically, when it is detected that the remaining replaceable number of filter cottons in the charging pile is 0, and the first wind speed difference of the currently used filter cotton during use has reached the preset second wind speed threshold, it is determined that the filter cotton remaining information at this time is no remaining.

[0078] It can be seen that in this embodiment, after it is determined that there is no available filter cotton, notification information is sent to the staff and the user respectively, thereby reducing the situation where the target charging pile is used for charging when there is no replaceable and usable filter cotton, thereby increasing the life of the charging pile.

[0079] S230, determining a first correlation between the first wind speed difference and a preset wind speed threshold, the first correlation including a first relationship, the first relationship indicating that the first wind speed difference is greater than the wind speed threshold, and if the first correlation is the first relationship, obtaining an internal temperature value inside the charging pile.

[0080] Among them, the preset wind speed threshold can be a preset value obtained through experiments or experience, which is used to judge the situation of the first wind speed difference. The first correlation relationship characterizes the size relationship between the first wind speed difference and the wind speed threshold, including the first relationship, and can also include the second relationship. If the first wind speed difference is greater than the wind speed threshold, that is, the first correlation relationship is the first relationship, then the internal temperature value inside the charging pile is obtained, and the second relationship characterizes that the first wind speed difference is less than or equal to the wind speed threshold.

[0081] Among them, if the first wind speed difference is less than or equal to the wind speed threshold, that is, the first correlation relationship is the second relationship, it means that the filter cotton of the current target charging pile works normally, and no other operations are performed, and the acquisition and judgment of the first wind speed difference are continued.

[0082] S240, determining a control instruction based on the internal temperature value, and sending the control instruction to the target charging pile, where the control instruction includes replacing the filter cotton.

[0083] After determining that the first correlation between the first wind speed difference and the preset wind speed threshold is the first correlation, the internal temperature value is obtained, and a control instruction for controlling the target charging pile is determined based on the internal temperature value. The control instruction may be to replace the filter cotton, which is used to instruct the target charging pile to replace the filter cotton. After determining the control instruction, the control instruction is sent to the target charging pile so that the target charging pile controls the filter cotton replacement device to perform the replacement operation. Specifically, after the control instruction is sent, the target charging pile receives the control instruction and controls the filter cotton replacement device to perform the replacement operation.

[0084] In a possible embodiment, the charging pile parameter set further includes the working state of the target charging pile, where the working state includes the charging state; if the working state is the charging state, determining the control instruction based on the internal temperature value, and sending the control instruction to the target charging pile includes:

[0085] 221. Determine a second correlation between the internal temperature value and a preset first temperature threshold, the second correlation including not exceeding the temperature threshold and exceeding the temperature threshold;

[0086] 222. If the second correlation is that the temperature threshold is not exceeded, obtaining an internal temperature set, the internal temperature set including a plurality of third temperature values ​​in a preceding time period; and determining a control instruction based on the internal temperature set;

[0087] 223. If the second correlation is exceeding the temperature threshold, obtain the ambient temperature value, and determine the control instruction based on the ambient temperature value.

[0088] Among them, a second correlation between the internal temperature value and the preset first temperature threshold is determined, and the second correlation may be within the temperature threshold and beyond the temperature threshold. If the temperature threshold is not exceeded, the internal temperature set of the stored previous time period is obtained, and the internal temperature set includes multiple third temperature values ​​of the previous time period. The above-mentioned previous time period is a period of time before the current moment. The time length of the previous time period can be preset, or it can be determined according to the charging time. The charging time is the time length from the moment when the target charging pile starts charging to the current moment. Specifically, the previous time period can be the charging time, or it can be a part of the previous time length according to the preset time period, which is not limited here. The third temperature value can be the temperature value obtained according to the preset step length in the previous time period. For example, a third temperature value can be obtained every 10 minutes. If the temperature threshold is exceeded, the ambient temperature value is obtained, and the control instruction is determined according to the ambient temperature value.

[0089] Specifically, if the temperature threshold is exceeded, the control instruction may be determined based on the relationship between the ambient temperature value and the internal temperature value.

[0090] It can be seen that in this embodiment, when the first wind speed difference of the target charging pile exceeds the wind speed threshold and the working state is the charging state, the control instruction is determined according to the relationship between the internal temperature value and the temperature threshold. Based on the multi-level judgment logic, the filter cotton replacement conditions of the target charging pile can be made more refined, thereby reducing the filter cotton cost to a certain extent.

[0091] In a possible embodiment, the target charging pile also includes a fan device, which is arranged at the air outlet, and the control instruction also includes increasing the fan speed. The control instruction is determined based on the internal temperature set, including: obtaining the end time of the current working state of the target charging pile, the end time of the working state is the charging end time of the current charging order of the target charging pile; determining the temperature rise rate based on the internal temperature set; based on a third correlation between the temperature rise rate and the first temperature threshold, the third correlation includes exceeding the order time and not exceeding the order time; if the third correlation is exceeding the order time, determining the control instruction is to replace the filter cotton; if the third correlation is not exceeding the order time, determining the control instruction is to increase the fan speed.

[0092] Among them, in addition to replacing the filter cotton, the control instruction can also be to increase the fan speed. After obtaining the internal temperature value, the end time of the current working state of the target charging pile is obtained, which can be the charging end time of the current charging vehicle. Then, the temperature trend is predicted based on the internal temperature value to obtain the temperature rise rate. According to the temperature rise rate and the charging end time, it is determined whether the time when the temperature rise reaches the first temperature threshold will exceed the charging end time. If it will exceed the charging end time, the control instruction is determined to replace the filter cotton. If it does not exceed the charging end time, the control instruction is determined to increase the fan speed.

[0093] Increasing the fan speed may be increasing the fan speed according to a preset fan speed. The preset fan speed may be a limit value of the fan or any value higher than the current speed, which is not specifically limited here.

[0094] Specifically, the temperature rise rate is determined based on the internal temperature set, and the specific process based on the third correlation between the temperature rise rate and the first temperature threshold may include: obtaining the temperature rise rate based on the pre-trained temperature trend prediction model and the internal temperature value. Among them, the training process of the temperature trend prediction model may include: performing data preprocessing on the fourth temperature value to obtain multiple standard fourth temperature values, the data preprocessing includes data cleaning and standardization processing, and the fourth temperature value is historical data used for training; constructing a temperature trend prediction model to be trained based on a neural network model, and the neural network model may include but is not limited to any one of a recurrent neural network, a long short-term memory network or a self-attention mechanism, and an autoregressive integral sliding average model; obtaining a first prediction result based on multiple standard fourth temperature values ​​and the temperature trend prediction model to be trained; obtaining an evaluation parameter based on the first prediction result and the actual result; and repeatedly training based on the evaluation parameter and the evaluation parameter threshold until a trained temperature trend prediction model whose evaluation parameter meets the evaluation parameter threshold is obtained. The specific process based on the third correlation between the temperature rise rate and the first temperature threshold may also include calculating by linear regression analysis and the like.

[0095] It can be seen that in this embodiment, by predicting the temperature rising rate when no processing is performed and the time to end charging, it is determined whether the temperature will reach the temperature threshold at the end. If it will be reached, the fan speed is increased, which is beneficial to slow down the rate of internal temperature increase, so that the charging end temperature does not reach the temperature threshold, thereby reducing the number of times the filter cotton is replaced and reducing costs.

[0096] In a possible embodiment, determining a control instruction based on an ambient temperature value includes: determining a temperature difference between an internal temperature value and an ambient temperature value; if the temperature difference is less than a temperature difference threshold, determining that the control instruction is to replace the filter cotton; if the temperature difference is greater than or equal to the temperature difference threshold, determining that the control instruction is to increase the fan speed.

[0097] The internal temperature value and the ambient temperature value may be obtained by a sensor, and the specific sensor is not limited here. After obtaining the internal temperature value and the ambient temperature value, the temperature difference is calculated, and then the control instruction is determined based on the size relationship between the temperature difference and the temperature difference threshold. Specifically, if the temperature difference is less than the temperature difference threshold, the control instruction is determined to replace the filter cotton. If the temperature difference is greater than or equal to the temperature difference threshold, the control instruction is determined to increase the fan speed to reduce the internal temperature rise rate.

[0098] Among them, while controlling to increase the fan speed, the charging power of the target charging pile can be appropriately reduced. Specifically, the fan speed and charging power can be comprehensively adjusted through the proportional-integral-differential (PID) control algorithm. Specifically, the process may include: determining the mapping relationship between the internal temperature value, the ambient temperature value, the fan speed, and the charging power based on the pre-trained simulation model; determining; determining the mapped target fan speed and target charging power based on the current internal temperature value, ambient temperature value, fan speed, and charging power; then determining the output control instruction based on the target fan speed, target charging power, fan speed, charging power, and PID control algorithm, and issuing a control instruction based on the output control instruction, and the control instruction also includes adjusting the fan speed based on the target fan speed and adjusting the charging power based on the target charging power. Specifically, a speed error is obtained based on the fan speed and the target fan speed, and a power error is obtained based on the target charging power and the charging power; a first speed control parameter is obtained based on the speed error and the first gain ratio, and a first power control parameter is obtained based on the power error and the first gain ratio; a second speed control parameter is obtained based on the speed error and the second gain ratio, and a second power control parameter is obtained based on the power error and the second gain ratio; a third speed control parameter is obtained based on the speed error and the third gain ratio, and a third power control parameter is obtained based on the power error and the third gain ratio; an output speed control parameter is obtained based on the first speed control parameter, the second speed control parameter and the third speed control parameter, and an output power control parameter is obtained based on the first power control parameter, the second power control parameter and the third power control parameter; and then specific control instructions are determined according to the output speed control parameter and the output power control parameter.

[0099] It can be seen that in this embodiment, by judging the difference between the ambient temperature value and the internal temperature value, it is judged whether it is necessary to increase the internal temperature to slow down the heating rate, thereby reducing the number of times the filter cotton is replaced.

[0100] In a possible embodiment, the working state also includes an idle state. If the working state is an idle state, a control instruction is determined based on the internal temperature value, and the control instruction is sent to the target charging pile, including: determining a second correlation between the internal temperature value and a preset first temperature threshold, the second correlation includes not exceeding the temperature threshold and exceeding the temperature threshold; if the second correlation is not exceeding the temperature threshold, the control instruction is determined to increase the fan speed. If the second correlation is exceeding the temperature threshold, the control instruction is determined to replace the filter cotton.

[0101] S250, if the control instruction is to replace the filter cotton, detect the second wind speed difference, the second wind speed difference is the difference in wind speed generated during the replacement operation of the filter cotton replacement equipment according to the control instruction, until it is detected that the second wind speed difference meets the standard range of wind speed difference, the standard range of wind speed difference is the difference range of wind speed when the filter cotton is not blocked.

[0102] Among them, after sending the control instruction, the second wind speed difference is continuously detected until it is detected that the second wind speed difference and the wind speed threshold meet the preset wind speed difference standard range. The above-mentioned wind speed difference standard range is the range of the wind speed difference between the air inlet and the air outlet when the filter cotton is not blocked, which can be obtained by experiment or based on empirical values, and is not specifically limited.

[0103] In a possible embodiment, the charging pile control system also includes a second terminal, and the second terminal is used for users to receive information transmitted by the server. After the step of detecting the second wind speed difference, the method also includes: detecting the wind speed change trend of the second wind speed difference within a preset detection time period, and the range relationship between the second wind speed difference and the standard range of the wind speed difference at the end of the preset detection time period; if the range relationship is that the second wind speed difference is not within the standard range of the wind speed difference, or the wind speed change trend does not meet the preset wind speed change trend standard, a fault message is sent to the first terminal, and the fault message is used to prompt the staff that a fault has occurred in the target charging pile or the filter cotton replacement equipment; the charging power of the target charging pile is reduced, and a prompt message is sent to the second terminal, and the prompt message is used to prompt the user that the charging power of the target charging pile is reduced.

[0104] The second terminal may be a mobile phone, watch, computer, tablet computer, or other device used by the user that can be used to receive information sent by the target charging pile.

[0105] The preset detection time period is a set detection time length, which can be any time length. In actual use, it can be set to 30 seconds or 1 minute, etc. It can be specifically determined according to the time length of the filter cotton replacement device to replace the filter cotton. For example, if it takes 30 seconds to replace the filter cotton, the preset detection time period can be set to 35 seconds, and the second wind speed difference is continuously detected within the preset detection time period. The wind speed difference standard range is the preset wind speed difference range.

[0106] The wind speed change trend of the wind speed difference can be a linear fitting relationship obtained based on the second wind speed difference obtained by sampling at each sampling step, which can characterize the trend of change. For example, each second wind speed difference can be arranged in chronological order to obtain a curve of second wind speed differences with varying magnitudes. The preset wind speed change trend standard can be a wind speed change trend set by experiment or experience, specifically, it can be a slope change condition of the curve, for example, the slope is less than 0 or less than a preset value.

[0107] Among them, if the second wind speed difference is not within the standard range of the wind speed difference, a fault message is sent to the first terminal, and the charging power of the target charging pile is reduced, and a prompt message is sent to the second terminal; if the wind speed change trend does not meet the preset wind speed change trend standard, a fault message is sent to the first terminal, and the charging power of the target charging pile is reduced, and a prompt message is sent to the second terminal. If the second wind speed difference is within the standard range of the wind speed difference, and the wind speed change trend meets the preset wind speed change trend standard, it indicates that the filter cotton has been successfully replaced, and a filter cotton replacement prompt message can be sent to the first terminal to inform the staff that the filter cotton of the target charging pile has been replaced.

[0108] It can be seen that in this embodiment, whether the replacement process is normal is judged according to the second wind speed difference value of the replacement process, so as to avoid the situation where the replacement still cannot work normally, reduce the probability of dangerous situations, and improve the life of the charging pile.

[0109] It can be seen that by implementing the embodiments of the present application, the filter cotton remaining information of the target charging pile is obtained, and the filter cotton remaining information includes the remaining amount; if the filter cotton remaining information is a remaining amount, the charging pile parameter set of the target charging pile is obtained, and the charging pile parameter set includes a first wind speed difference, and the first wind speed difference is a first correlation between the first wind speed difference and the preset wind speed threshold value determined based on the wind speeds of the air inlet and the air outlet, and the first correlation includes a first relationship, and the first relationship characterizes that the first wind speed difference is greater than the wind speed threshold value. If the first correlation is the first relationship, the internal temperature value inside the charging pile is obtained; a control instruction is determined based on the internal temperature value, and a control instruction is sent to the target charging pile, and the control instruction includes replacing the filter cotton; if the control instruction is to replace the filter Cotton, detect the second wind speed difference, the second wind speed difference is the difference in wind speed generated during the replacement operation of the filter cotton replacement equipment according to the control instruction, until it is detected that the second wind speed difference meets the standard range of wind speed difference, the standard range of wind speed difference is the difference range of wind speed when the filter cotton is not blocked. Compared with the existing strategy of directly judging whether it needs to be replaced according to the wind speed and informing the staff to replace the filter, this solution sets up a filter cotton replacement device and adds multi-level decision-making such as filter cotton residue, wind speed, and temperature to obtain control instructions, so as to control the filter cotton replacement device to automatically replace the filter cotton, which reduces the workload of the staff on the basis of improving the life of the charging pile, improves the efficiency of filter cotton replacement, and saves the filter cotton cost to a certain extent.
