Description

Technical Field

[0001] This application relates to the technical field of charging piles, and in particular to a method, system, device and storage medium for monitoring power failure of charging piles. Background Art

[0002] Power failure of a charging pile means that when a charging device is connected to the charging pile and charging, the charging device abnormally disconnects from the charging pile before reaching the charging requirements set by the user; for example, after the charging device is connected to the charging pile, the user sets a charging time of 2 hours through the APP, but the charging pile disconnects from the charging device before being fully charged for 2 hours, which is regarded as power failure of the charging pile.

[0003] In related technologies, it is often found that when charging piles in some communities or office buildings charge charging devices, the charging devices are unplugged by others, resulting in the charging devices not being able to meet the charging requirements, thus affecting the charging experience of the users who have already charged. Summary of the Invention

[0004] In order to improve the charging experience of the users who have already charged, this application provides a method, system, device and storage medium for monitoring power failure of charging piles.

[0005] In a first aspect, this application provides a method for monitoring power failure of a charging pile, adopting the following technical solution:

[0006] A method for monitoring power failure of a charging pile includes:

[0007] Assign a corresponding charging QR code to each idle charging pile within the monitoring area, and the charging QR code jumps to the corresponding charging interface in response to a QR code scanning request;

[0008] Determine whether there is an occupied idle charging pile;

[0009] If so, mark the occupied idle charging pile as an occupied charging pile, and generate an occupancy QR code. The occupancy QR code replaces the charging QR code corresponding to the occupied charging pile, and the occupancy QR code jumps to the corresponding charging pile allocation interface in response to a QR code scanning request.

[0010] By adopting the above technical solution, an idle charging pile represents a charging pile that is not connected to a charging device. The charging pile is assigned a charging QR code, so that after the user connects the charging device to the charging pile, the user can directly enter the charging interface through the charging QR code to operate and realize the charging of the charging device by the charging pile. When the charging pile is working, it is marked as an occupied charging pile and generates an occupancy QR code to replace the charging QR code. In this way, when other users want to use this charging pile, even if they scan the code, they will not enter the charging interface, but enter the charging pile allocation interface to provide information about other available charging piles, guiding other users to quickly find a substitute idle charging pile for charging, thus preventing other users from unplugging the current charging device and improving the charging experience of the charged users.

[0011] Optionally, the monitoring method further includes:

[0012] Determine whether there is a disconnection between the occupied charging pile and the charged device;

[0013] If so, mark the powered-off occupied charging pile as a powered-off charging pile, and determine whether the charged duration of the powered-off charging pile reaches the corresponding charging requirement;

[0014] If so, convert the corresponding occupancy QR code into the charging QR code;

[0015] If not, then further determine whether the charged duration matches the charging disconnection duration preset by the charged user;

[0016] If so, convert the corresponding occupancy QR code into the charging QR code, and send a first prompt message to the charged user terminal, where the first prompt message is used to indicate that "the charging device has reached the charging disconnection duration and is disconnected".

[0017] By adopting the above technical solution, if other users forcibly unplug the charged device, since the charging pile is disconnected from the charged device, the charging pile is marked as a powered-off charging pile, and it is determined whether the charged duration of the powered-off charging pile reaches the corresponding charging requirement. If so, the corresponding occupancy QR code can be directly converted into the charging QR code, and other users can use this charging pile for charging; if not, it is further determined whether the charged duration matches the charging disconnection duration preset by the user. If so, the corresponding occupancy QR code can be converted into the charging QR code, and a first prompt message is sent to the charged user terminal to remind the charged user; thus, available resources can be released in a timely manner and the accuracy of resource allocation can be optimized.

[0018] Optionally, the step of further determining whether the charged duration matches the charging disconnection duration preset by the charged user further includes:

[0019] If not, collect and store the video information at the power-off charging pile, control the power-off charging pile to output a warning message, and send a second prompt message to the charged user terminal; the warning message is used to indicate that "the charging device is not fully charged and is prohibited from use"; the second prompt message is used to indicate that "the charging device is abnormally disconnected".

[0020] Receive the monitoring and viewing instruction sent by the charged user terminal.

[0021] Based on the monitoring and viewing instruction, send the video information to the charged user terminal.

[0022] By adopting the above technical solution, if the charged is unplugged by other users before the set charging disconnection duration is reached, the video information at the power-off charging pile can be collected and stored, and the power-off charging pile can be controlled to output a warning message to warn other users, and a second prompt message can be sent to the charged user terminal to prompt the charged user; when the charged user sends a monitoring and viewing instruction, the stored video information is sent to the charged user terminal, so as to facilitate the charged user to trace back.

[0023] Optionally, the steps before the occupancy QR code jumps to the charging pile allocation interface after responding to the scan request include:

[0024] Obtain the first position information of the idle charging pile, the second position information of the occupied charging pile with the charged duration reaching the corresponding charging requirement, and the third position information of the occupied charging pile with the charged duration matching the charging disconnection duration set by the charged user.

[0025] Judge whether the quantities of the first position information, the second position information and the third position information are all 0;

[0026] If not, screen the available charging pile closest to the current user according to the personnel position information of the current user and display it in the charging pile allocation interface.

[0027] By adopting the above technical solutions, the utilization rate of charging piles is improved: by dynamically monitoring the status of charging piles (idle, occupied, about to be available), the system can allocate charging resources more efficiently and reduce the idle time of charging piles. The user experience is optimized: according to the user's location and charging needs, the system intelligently recommends the nearest available charging piles, reducing the time for users to search for charging piles and enhancing convenience. Dynamic scheduling is supported: by monitoring the charged duration and the charging disconnection duration set by the user, the system can predict the available time of charging piles and allocate the about-to-be-available charging piles to users in advance to avoid waste of resources. The waiting time is reduced: through real-time screening and allocation, users can quickly find available charging piles, reducing the queuing waiting time and enhancing the charging efficiency. Intelligent management: the system can automatically process complex charging pile status information and perform intelligent matching according to user needs, reducing manual intervention and lowering management costs.

[0028] Optionally, after determining that the quantities of the first location information, the second location information, and the third location information are not all zero, the following steps are further included:

[0029] Generate the priority of available charging piles from near to far from the current user according to the personnel location information of the current user;

[0030] Obtain the image information of each of the available charging piles in the priority;

[0031] According to the image information, screen the available charging pile with the largest parking space interval and display it in the charging pile allocation interface.

[0032] By adopting the above technical solutions, the user experience is enhanced: by screening the charging pile with the largest parking space interval, it is ensured that users have enough space to park and operate when using, avoiding inconveniences caused by narrow spaces. The allocation of charging piles is optimized: not only considering the distance factor, but also combining the image information to analyze the actual availability of charging piles, avoiding the ineffective use of charging piles due to space limitations. The charging efficiency is improved: through the dual screening of priority and image information, the charging piles can be allocated more accurately, reducing the time for users to search and wait.

[0033] Optionally, the monitoring method further includes:

[0034] If the quantities of the first location information, the second location information, and the third location information are all zero, then obtain the error value between the charged duration of the occupied charging pile or the idle charging pile with a non-zero location quantity and the corresponding charging requirement;

[0035] Screen the minimum error value;

[0036] Adjust the power of the charging pile corresponding to the minimum error value according to the minimum error value and the distance between the position of the charging pile corresponding to the minimum error value and the position of the person, and display the basic information of the charging pile in the charging pile allocation interface.

[0037] By adopting the above technical solutions, resource release acceleration in extreme scenarios: By increasing the power of the charging pile closest to completion, significantly shortening its charging time, quickly releasing the charging pile resources, and alleviating the congestion problem of all charging piles being occupied during peak periods. Minimizing user waiting time: Prioritize adjusting the "minimum error value pile" closest to the current user, reducing the subsequent moving time of the user to the charging pile, achieving a two-dimensional optimization of "time + space"; enabling the available charging pile to complete the current charging work when other users move to this available charging pile.

[0038] Optionally, the step of adjusting the power of the charging pile corresponding to the minimum error value includes:

[0039] Input the minimum error value, the distance between the position of the charging pile corresponding to the minimum error value and the position of the person, and the current power corresponding to the charging pile into a pre-constructed power adjustment formula to obtain the adjusted power of the charging pile;

[0040] The power adjustment formula is: P = P0 + K1×Δt - K2×d; where P is the adjusted power, P0 is the current power, K1 is the adjustment coefficient of the minimum error value affecting the power, Δt is the minimum error value, K2 is the adjustment coefficient of the distance between the position of the charging pile corresponding to the minimum error value and the position of the person affecting the power, and d is the distance between the position of the charging pile corresponding to the minimum error value and the position of the person.

[0041] In a second aspect, the present application provides a monitoring system for charging pile power failure, adopting the following technical solutions:

[0042] A monitoring system for charging pile power failure, comprising:

[0043] A two-dimensional code generation module, used to assign a corresponding charging two-dimensional code to each idle charging pile within the monitoring area, and the charging two-dimensional code jumps to the corresponding charging interface in response to a scanning request;

[0044] A judgment module, used to judge whether there is an occupied idle charging pile;

[0045] An identification module, used to mark the occupied idle charging pile as an occupied charging pile and generate an occupancy two-dimensional code after the idle charging pile is occupied. The two-dimensional code generation module replaces the charging two-dimensional code corresponding to the occupied charging pile with the occupancy two-dimensional code, and the occupancy two-dimensional code jumps to the corresponding charging pile allocation interface in response to a scanning request.

[0046] By adopting the above technical solution, an idle charging pile represents a charging pile that is not connected to a charging device. The charging pile is given a charging QR code, so that after the user connects the charging device to the charging pile, the user can directly enter the charging interface through the charging QR code to operate and realize the charging of the charging device by the charging pile. When the charging pile is working, it is marked as an occupied charging pile and generates an occupancy QR code to replace the charging QR code. In this way, when other users want to use this charging pile, even if they scan the code, they will not enter the charging interface, but enter the charging pile allocation interface to provide information about other available charging piles, guiding other users to quickly find a substitute idle charging pile for charging, thus preventing other users from unplugging the current charging device and improving the charging experience of the already charged users.

[0047] In a third aspect, the present application provides a device, adopting the following technical solution:

[0048] A device, comprising:

[0049] A memory storing a monitoring program for the power failure of the charging pile;

[0050] A processor for executing the program stored on the memory to implement the steps of the above-mentioned monitoring method for the power failure of the charging pile.

[0051] In a fourth aspect, the present application provides a computer-readable storage medium, adopting the following technical solution:

[0052] A computer-readable storage medium storing a computer program that can be loaded and executed by a processor to implement the above-mentioned monitoring method for the power failure of the charging pile.

[0053] In summary, the present application has at least the following beneficial effects:

[0054] 1. An idle charging pile represents a charging pile that is not connected to a charging device. The charging pile is given a charging QR code, so that after the user connects the charging device to the charging pile, the user can directly enter the charging interface through the charging QR code to operate and realize the charging of the charging device by the charging pile. When the charging pile is working, it is marked as an occupied charging pile and generates an occupancy QR code to replace the charging QR code. In this way, when other users want to use this charging pile, even if they scan the code, they will not enter the charging interface, but enter the charging pile allocation interface to provide information about other available charging piles, guiding other users to quickly find a substitute idle charging pile for charging, thus preventing other users from unplugging the current charging device and improving the charging experience of the already charged users.

[0055] 2. If another user forcibly unplug the charged device, since the charging pile is disconnected from the charged device, the charging pile is marked as a powered-off charging pile, and it is determined whether the charged duration of the powered-off charging pile meets the corresponding charging requirements. If so, directly convert the corresponding occupied QR code into a charging QR code, and other users can use this charging pile to charge; if not, it is determined again whether the charged duration matches the charging disconnection duration preset by the user. If so, the corresponding occupied QR code can be converted into a charging QR code, and a first prompt message is sent to the terminal of the charged user to remind the charged user; thus, available resources can be released in a timely manner and the accuracy of resource allocation can be optimized; if the set charging disconnection duration is not reached and the charged device is unplugged by another user, the video information at the powered-off charging pile can be collected and stored, and the powered-off charging pile is controlled to output a warning message to warn other users, and a second prompt message is sent to the terminal of the charged user to prompt the charged user; when the charged user sends a monitoring and viewing instruction, the stored video information is sent to the terminal of the charged user, so as to facilitate the charged user to trace back.

[0063] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the attached drawings in the embodiments of the present invention Figure 1 - attached Figure 6, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0064] The first embodiment of this application discloses a method for monitoring the power failure of a charging pile. Refer to Figure 1 , as an implementation manner of this monitoring method, this monitoring method may include S110 - S140:

[0065] S110, assign a corresponding charging QR code to each idle charging pile in the monitoring area. The charging QR code will jump to the corresponding charging interface in response to a QR code scanning request;

[0066] S120, determine whether there is an idle charging pile occupied;

[0067] S130, if so, mark the occupied idle charging pile as an occupied charging pile and generate an occupancy QR code. The occupancy QR code replaces the charging QR code corresponding to the occupied charging pile. The occupancy QR code will jump to the corresponding charging pile allocation interface in response to a QR code scanning request;

[0068] S140, if not, do not respond.

[0069] Specifically, the monitoring area refers to an area within a community, office building, park, etc. where a charging pile is installed, and the area of the monitoring area can be modified and set. When each charging pile is idle, it is marked as an idle charging pile, and the display screen at the charging pile displays the charging QR code externally. The charging interface includes information such as the corresponding charging pile number, power information, charging requirement information, charging disconnection setting information, and payment information, etc. The charging requirement information represents options for the conventional charging duration, and the charging disconnection setting information represents options for the disconnection charging duration. It should be noted that if a charging pile corresponds to two charging ports, each charging port can be numbered as an independent charging pile, that is, each charging port corresponds to a charging QR code or an occupancy QR code.

[0070] By obtaining the identifier of the charging pile, it is determined whether the idle charging pile is occupied. If the idle charging pile is connected to the charging device and the user's payment is successful, it indicates that the idle charging pile is occupied, and this charging pile is marked as an occupied charging pile. And an occupancy QR code is generated to replace the charging QR code to achieve the transformation of the QR code. The charging pile allocation interface includes the charging status of each charging pile, the number of the nearest available charging pile to the current user, the number of the available charging pile with the largest stay spacing, and the number of the occupied charging pile with power adjustment, etc. The charging status includes the charged duration, charging power, etc.

[0071] Refer to Figure 2, before jumping to the charging pile allocation interface, S210 - S260 can be executed:

[0072] S210, obtain the first position information of idle charging piles, the second position information of occupied charging piles whose charged duration reaches the corresponding charging requirements, and the third position information of occupied charging piles whose charged duration matches the charging disconnection duration set by the charged user;

[0073] S220, determine whether the quantities of the first position information, the second position information, and the third position information are all 0;

[0074] S230, if not, then filter out the available charging pile closest to the current user according to the personnel position information of the current user, and display it in the charging pile allocation interface;

[0075] S240, if so, then obtain the error value between the charged duration of the occupied charging pile or idle charging pile with a non - zero position quantity and the corresponding charging requirements;

[0076] S250, filter out the minimum error value;

[0077] S260, according to the minimum error value, the distance between the position of the charging pile corresponding to the minimum error value and the personnel position, adjust the power of the charging pile corresponding to the minimum error value, and display the basic information of this charging pile in the charging pile allocation interface.

[0078] Specifically, the current user refers to the user who wants to use this charging pile subsequently. The personnel position information of the current user can be obtained through GPS positioning on the mobile terminal of the current user. If there are available charging piles, then according to the personnel position of the current user and the positions of the available charging piles, determine the available charging pile closest to the personnel position. If there are no available charging piles, then obtain the error value between the charged duration of the occupied charging pile or idle charging pile and the corresponding charging requirements, and filter out the minimum error value from multiple error values.

[0079] And input the minimum error value, the distance between the position of the charging pile corresponding to the minimum error value and the personnel position, and the current power of this charging pile into the pre - constructed power adjustment formula to obtain the adjusted power of this charging pile, so that this charging pile outputs according to the adjusted power.

[0080] The power adjustment formula is: P = P0 + K1×Δt - K2×d; where, P is the adjusted power, P0 is the current power, K1 is the adjustment coefficient of the minimum error value affecting the power, Δt is the minimum error value, K2 is the adjustment coefficient of the distance between the position of the charging pile corresponding to the minimum error value and the personnel position affecting the power, and d is the distance between the position of the charging pile corresponding to the minimum error value and the personnel position.

[0081] The basic information of the charging pile includes the charging pile number, the location within the monitoring area, the charging power of the charging pile, the charged duration, the remaining charging duration, etc.

[0082] For example, if the current power of the available charging pile P0 is 30 kW, K1 = 0.5 kW / hour, K2 = 0.01 kW / m, the minimum error value Δt = 2 hours, and the distance between the available charging pile and the current user's location is 2 meters (i.e., d = 2 meters), then the adjusted power P = 30 + 0.5×2 - 0.01×2 = 30.98 kW.

[0083] In addition, referring to Figure 3 , after the judgment in S220 is No, the steps that the monitoring method can further execute include S231 - S233:

[0084] S231, generate the priority of the available charging piles from near to far from the current user according to the personnel location information of the current user;

[0085] S232, obtain the image information of each available charging pile in the priority;

[0086] S233, screen the available charging pile with the largest stay spacing according to the image information and display it in the charging pile allocation interface.

[0087] Specifically, a camera is installed at each charging pile display screen to collect video information or image information at the charging pile. After the image is collected, the spacing between adjacent charging devices at the charging pile can be recognized through a conventional image recognition algorithm to screen the largest stay spacing, so as to display the available charging pile corresponding to the largest stay spacing in the charging pile allocation interface.

[0088] The above is for the case of preferentially scanning the code without unplugging the charged device. If the charged device is preferentially unplugged, referring to Figure 4 and Figure 5 , the monitoring method may include S310 - S390:

[0089] S310, judge whether there is an occupied charging pile disconnected from the charged device;

[0090] S320, if not, do not respond;

[0091] S330, if so, mark the powered-off occupied charging pile as a powered-off charging pile and judge whether the charged duration of the powered-off charging pile reaches the corresponding charging requirement;

[0092] S340, if so, convert the corresponding occupied QR code into a charging QR code;

[0093] S350, if not, then judge whether the charged duration matches the charging disconnection duration preset by the charged user;

[0094] S360, if so, convert the corresponding occupied QR code into a charging QR code, and send a first prompt message to the charged user terminal;

[0095] S370, if not, collect and store the video information at the power-off charging pile, control the power-off charging pile to output a warning message, and send a second prompt message to the charged user terminal;

[0096] S380, receive the monitoring view instruction sent by the charged user terminal;

[0097] S390, based on the monitoring view instruction, send the video information to the charged user terminal.

[0098] Specifically, the first prompt message is used to represent that "the charging device has reached the charging disconnection duration and the connection is disconnected". The warning message is used to represent that "the charging device is not fully charged and is prohibited from use"; the second prompt message is used to represent that "the charging device is abnormally disconnected". The content of the first prompt message, warning message and second prompt message can be edited and modified as long as it conforms to the representation meaning.

[0099] In addition, an audible and visual alarm is installed at each display screen, and the audible and visual alarm responds to the warning message and performs a warning action.

[0100] In addition, after sending the second prompt message, the charged user can enter the charging APP or mini-program, click on the monitoring view virtual button to send a monitoring view instruction. When receiving the monitoring view instruction sent by the charged user terminal, send the video information to the charged user terminal, so as to facilitate the charged user to trace the user who unplugged the charging device or give feedback to the property management, etc.

[0101] A scenario of this embodiment is as follows:

[0102] If the monitored area is a charging pile layout area under an office building, the idle charging piles in the monitored area are assigned charging QR codes; when it is determined that an idle charging pile is marked as an occupied charging pile, it indicates that the charging pile has been connected to a charging device and is charging, so a corresponding occupied QR code is generated to replace the charging QR code. If a user wants to use this charging pile:

[0103] In one case, if the user directly scans the code, the system will obtain the first location information of the idle charging piles, the second location information of the occupied charging piles whose charged duration has reached the corresponding charging requirements, and the third location information of the occupied charging piles whose charged duration matches the charging disconnection duration set by the charged user. Then, it will judge whether the number of the first location information, the second location information, and the third location information is 0. If so, it will obtain the error value between the charged duration of the occupied or idle charging pile with a non-zero location number and the corresponding charging requirements, and filter out the minimum error value. Then, it will input the minimum error value, the distance between the charging pile location corresponding to the minimum error value and the personnel location, and the current power of the charging pile into the pre-constructed power adjustment formula to obtain the adjusted power of the charging pile, so that the charging pile outputs according to the adjusted power, and display the basic information of the charging pile in the charging pile allocation interface.

[0104] In another case, if the user directly unpluggs the charged device, mark the occupied charging pile with power-off as a power-off charging pile, and judge whether the charged duration of the power-off charging pile has reached the corresponding charging requirements. If not, then judge whether the charged duration matches the charging disconnection duration pre-set by the charged user. If not, collect and store the video information at the power-off charging pile, control the power-off charging pile to output a warning message, and send a second prompt message to the charged user terminal; when receiving the monitoring and viewing instruction sent by the charged user terminal, send the video information to the charged user terminal.

[0105] Based on the above method embodiment, the second embodiment of the present application discloses a monitoring system for charging pile power-off. Refer to Figure 6 , the monitoring system may include:

[0106] A two-dimensional code generation module 101, configured to assign a corresponding charging two-dimensional code to each idle charging pile within the monitoring area. The charging two-dimensional code jumps to the charging interface in response to a code scanning request;

[0107] A judgment module 102, configured to judge whether there is an idle charging pile occupied;

[0108] An identification module 103, configured to mark the occupied idle charging pile as an occupied charging pile after the idle charging pile is occupied; the two-dimensional code generation module 101 generates an occupancy two-dimensional code, and the occupancy two-dimensional code replaces the charging two-dimensional code corresponding to the occupied charging pile. The occupancy two-dimensional code jumps to the charging pile allocation interface in response to a code scanning request;

[0109] An information sending module 104, configured to send a first prompt message to the charged user terminal, and the first prompt message is used to represent that "the charging device has reached the charging disconnection duration and the connection is disconnected";

[0111] The image acquisition module 105 is configured to acquire and store video information at the powered-off charging pile when the charged duration does not match the charging disconnection duration preset by the user;

[0112] The control module 106 is configured to control the powered-off charging pile to output a warning message, and the information sending module 104 also sends a second prompt message to the charged user terminal; the warning message is used to indicate that "the charging device is not fully charged and is prohibited from being used"; the second prompt message is used to indicate that "the charging device is abnormally disconnected";

[0113] The instruction receiving module 107 is configured to receive a monitoring and viewing instruction sent by the charged user terminal; the information sending module 104 sends the video information to the charged user terminal based on the monitoring and viewing instruction.

[0114] The modules of the monitoring system for the charging pile power failure correspond one by one to the monitoring method for the charging pile power failure, and will not be elaborated here.
