Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a method for querying the status of charging piles based on the Internet of Things. Background Technology

[0002] With the strategic transformation of the global energy structure and the deep penetration of the concept of sustainable development, the new energy vehicle industry, as a key lever for achieving carbon peaking and carbon neutrality goals in the transportation sector, has ushered in unprecedented development opportunities. New energy vehicles, represented by pure electric vehicles, are gradually replacing traditional fuel vehicles centered on internal combustion engines, becoming the mainstream choice for public transportation, due to their significant advantages in environmental protection and energy conservation. These vehicles use electricity as their sole or primary driving energy source, relying on the energy stored in their power battery packs for propulsion. This fundamental shift in energy paradigms also places new and higher technical demands on their energy supply infrastructure. The refueling process for traditional gasoline vehicles is a physical fluid filling process that takes very little time, usually within 3 to 5 minutes, achieving a highly mobile replenishment mode that is almost "refuel and go". In contrast, the charging process for new energy vehicles is essentially an electrochemical reaction process. Even in DC fast charging mode, it usually takes 30 minutes to 1 hour to replenish the battery from a low charge state to 80%, while AC slow charging takes several hours or even overnight. This difference in energy replenishment time fundamentally determines that the unit service time of charging pile facilities is much longer than that of gas pumps, resulting in new energy vehicle owners having to queue for charging.

[0003] New energy vehicle parking lots are typically located in shopping malls, hotels, or popular tourist attractions. New energy vehicle owners usually visit these locations during weekdays and holidays. If the journey is long, they need to recharge upon arrival. However, before traveling, owners cannot check the availability of charging stations in the parking lot. Their travel decisions lack data support, relying solely on static, historical charging station maps for navigation. Upon arrival, owners search for available charging stations. If all stations are occupied, they spend considerable time searching the entire parking lot before waiting in long queues. Alternatively, they may choose other nearby parking lots, but the availability of charging stations there is uncertain, potentially leading to another time-consuming search and long waits, resulting in significant opportunity costs. Meanwhile, when new energy vehicle owners arrive at their destination for the first time and search for charging stations in parking lots, the in-car intelligent voice system constantly reminds them of the vehicle's remaining battery level, increasing their psychological burden and significantly impacting their travel experience. If the remaining battery level is insufficient to reach the designated parking lot, the vehicle may run out of power and break down on public roads, in underground garages, or at transportation hubs. This not only endangers the safety of passengers but may also cause traffic congestion and even secondary accidents, requiring the use of social rescue resources and increasing public management costs. On the other hand, due to a lack of information transparency, new energy vehicle owners tend to flock to a few well-known or familiar charging stations, causing these stations to operate under overload for extended periods, resulting in severe queues and a surge in average service waiting times. Conversely, some relatively remote or newly constructed charging stations are underutilized, leading to serious resource idleness. This resource mismatch macroscopically reduces the average utilization rate and return on investment of the entire charging network. Summary of the Invention

[0004] The purpose of this invention is to provide a charging pile status query method based on the Internet of Things, thereby solving the aforementioned problems in the prior art.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A method for querying the status of charging piles based on the Internet of Things, the method comprising the following steps: The server receives and stores the parking lot address and the corresponding query system QR code; the terminal logs into the server to search for parking lots near the destination and obtains the corresponding query system QR code. The terminal scans the QR code of the query system to log in to the corresponding parking lot management platform and obtain the usage status of the parking lot charging piles.

[0006] By connecting various parking lot management platforms together, users can first search for parking lots near their destination using electronic devices such as mobile phones and tablets before traveling. They will then obtain a QR code for the parking lot query system, scan it to log in to the corresponding parking lot management platform, and check the availability of charging stations. Users can access detailed information about the charging station availability before departure. If no charging stations are available at the selected parking lot, users can continue to check the availability of charging stations in other parking lots near their destination. This allows users to know the availability of charging stations near their destination before traveling, enabling them to choose a parking lot with sufficient available charging stations. This effectively avoids long waits at parking lots where no charging stations are available, or vehicles running out of power and becoming stranded on the road while trying to find another parking lot. Because this solution allows new energy vehicle users to check the availability of charging stations near their destination before traveling, and if no available charging stations are found near their destination, they can choose to use parking lots further away with available charging stations. This effectively increases the utilization rate of relatively remote or newly built charging stations, avoids resource idleness, and improves the user's travel experience.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the usage status of the parking lot charging piles includes the number of currently available charging piles in the parking lot and the number of currently available charging piles for reservation.

[0009] The further beneficial effects of adopting the above are: providing the number of available charging stations for users to refer to when they go to which parking lot, and allowing users to reserve charging stations before going to the parking lot, thus avoiding the situation where available charging stations are used by vehicles entering during the journey, resulting in no charging stations available when users arrive at the parking lot.

[0010] Furthermore, the usage status of the parking lot charging pile also includes the amount of electricity being charged by the charging pile for the new energy vehicle being charged, and the estimated time for completion of charging.

[0011] The further beneficial effect of adopting the above is that when it is found that there are no available charging piles in the corresponding parking lot, it is possible to make plans in advance based on the estimated time for the corresponding new energy vehicle to complete charging or which charging piles will be available at the corresponding time.

[0012] Furthermore, the formula for calculating the number of currently available charging stations is N=MX*S; where N is the number of currently available charging stations, M is the number of currently available charging stations, X is the average number of vehicles entering the parking lot, and S is the reservation duration.

[0013] The further beneficial effect of adopting the above is that, since the vehicles entering the parking lot include gasoline vehicles and electric vehicles, and the electric vehicles include electric vehicles that need to be charged and electric vehicles that do not need to be charged, the number of currently available charging piles calculated based on the average traffic flow entering the parking lot is the minimum number, which effectively ensures that after a user makes a reservation, there will be an available charging pile available for him / her when he / she arrives at the parking lot within the reserved time.

[0014] Furthermore, the parking management platform pushes the remaining reservation time to the terminal at preset intervals.

[0015] The further beneficial effect of adopting the above is that it enables users to know the remaining reservation time in a timely manner and arrive at the parking lot in time within the reservation period.

[0016] A charging pile status query system based on the Internet of Things, characterized in that it includes a server and a terminal; The server is used to receive and store the parking lot address and the corresponding query system QR code; The terminal is used to log in to the server to search for parking lots near the destination and obtain the corresponding query system QR code; it is also used to scan the query system QR code to log in to the corresponding parking lot management platform and obtain the usage status of the parking lot charging piles.

[0017] The further beneficial effects of adopting the above approach are as follows: By connecting various parking lot management platforms to the network, users can first search for parking lots near their destination using electronic devices such as mobile phones and tablets before traveling. They can then obtain a QR code for the parking lot query system, scan the QR code to log in to the corresponding parking lot management platform, and obtain information on the availability of charging piles. Users can access detailed information on the availability of charging piles in the corresponding parking lot before departure. If no charging piles are available at the searched parking lot, users can continue to search for the availability of charging piles in other parking lots near their destination. This allows users to know the availability of charging piles in parking lots near their destination before traveling, enabling them to choose a parking lot with sufficient available charging piles. This effectively avoids the situation of arriving at a parking lot only to find no available charging piles, waiting for a long time, or running out of battery and being stranded on the road while trying to find another parking lot. Because this solution allows new energy vehicle users to check the availability of charging piles in parking lots near their destination before traveling, they can choose to use a parking lot further away if no available charging piles are found. This effectively increases the utilization rate of relatively remote or newly built charging piles, avoids resource idleness, and improves the user's travel experience.

[0018] Furthermore, the usage status of the parking lot charging piles includes the number of currently available charging piles in the parking lot and the number of currently available charging piles for reservation.

[0019] The further beneficial effects of adopting the above are: providing the number of available charging stations for users to refer to when they go to which parking lot, and allowing users to reserve charging stations before going to the parking lot, thus avoiding the situation where available charging stations are used by vehicles entering during the journey, resulting in no charging stations available when users arrive at the parking lot.

[0020] Furthermore, the usage status of the parking lot charging pile also includes the amount of electricity being charged by the charging pile for the new energy vehicle being charged, and the estimated time for completion of charging.

[0021] If a parking lot has no available charging stations, it can be planned in advance by considering the estimated time for the new energy vehicle to complete charging or which charging stations will be available at that time.

[0022] Furthermore, the formula for calculating the number of currently available charging stations is N=MX*S; where N is the number of currently available charging stations, M is the number of currently available charging stations, X is the average number of vehicles entering the parking lot, and S is the reservation duration.

[0023] The further beneficial effect of adopting the above is that, since the vehicles entering the parking lot include gasoline vehicles and electric vehicles, and the electric vehicles include electric vehicles that need to be charged and electric vehicles that do not need to be charged, the number of currently available charging piles calculated based on the average traffic flow entering the parking lot is the minimum number, which effectively ensures that after a user makes a reservation, there will be an available charging pile available for him / her when he / she arrives at the parking lot within the reserved time.

[0024] Furthermore, the terminal is also used to receive the remaining reservation time pushed by the parking management platform at preset intervals.

[0025] The further beneficial effect of adopting the above is that it enables users to know the remaining reservation time in a timely manner and arrive at the parking lot in time within the reservation period. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

Furthermore, "above," "on top of," and "on top" can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0031] Example 1 like Figure 1 As shown, a method for querying the status of charging piles based on the Internet of Things (IoT) includes the following steps: The S101 server receives and stores the address of the parking lot and the corresponding query system QR code; the S201 terminal logs into the server to search for parking lots near the destination and obtains the corresponding query system QR code. The S301 terminal scans the QR code of the query system to log in to the corresponding parking lot management platform and obtain the usage status of the parking lot charging piles.

[0032] By connecting various parking lot management platforms together, users can first search for parking lots near their destination using electronic devices such as mobile phones and tablets before traveling. They will then obtain a QR code for the parking lot query system, scan it to log in to the corresponding parking lot management platform, and check the availability of charging stations. Users can access detailed information about the charging station availability before departure. If no charging stations are available at the selected parking lot, users can continue to check the availability of charging stations in other parking lots near their destination. This allows users to know the availability of charging stations near their destination before traveling, enabling them to choose a parking lot with sufficient available charging stations. This effectively avoids long waits at parking lots where no charging stations are available, or vehicles running out of power and becoming stranded on the road while trying to find another parking lot. Because this solution allows new energy vehicle users to check the availability of charging stations near their destination before traveling, and if no available charging stations are found near their destination, they can choose to use parking lots further away with available charging stations. This effectively increases the utilization rate of relatively remote or newly built charging stations, avoids resource idleness, and improves the user's travel experience.

[0033] In practice, users scan the QR code of the query system via their terminals. If they do not have an account, they can click the registration box and register an account according to the system prompts. During the registration process, users need to fill in the vehicle's license plate number. After completing the registration, they can log in and query the usage status of the parking lot charging piles through the parking lot management platform. They can also query the corresponding charging time and the corresponding fee. Furthermore, when users arrive at the parking lot and finish charging, they can also pay online through the parking lot management platform. This can effectively avoid too many vehicles queuing at the parking lot exit to pay, and can effectively improve the user's travel experience.

[0034] Example 2 This embodiment is a further improvement on embodiment 1, as detailed below: The usage status of the parking lot charging piles includes the number of currently available charging piles and the number of currently available charging piles for reservation.

[0035] The system provides parameters on the number of available charging stations for users to refer to when they are going to a parking lot. Users can reserve charging stations before going to the parking lot to avoid the situation where available charging stations are used by vehicles entering during the journey, resulting in no charging stations available when users arrive at the parking lot.

[0036] In practice, the number of available charging piles refers to those that are unused and not reserved. Further information on the usage status of parking lot charging piles includes the time when an available charging pile completes charging and the duration of use. A timer is installed on each charging pile. The timer starts when the charging pile begins charging (i.e., when the charging head connects to the charging port of the new energy vehicle), triggering the timer switch. When charging is complete and the user disconnects the charging head from the charging port, the timer switch is triggered again, stopping the timer. This records the usage time of the charging pile and the moment it stops. When a user finds an available charging pile through the parking lot management platform, they can see the number of times the charging pile was used that day before charging ended, the total usage time, and the idle time from the time charging ended to the time the user inquired. This idle time is the cool-down period from the time the charging pile ended to the time the user inquired. Therefore, users can use this information to select the optimal available charging pile when there are enough available charging piles. When charging stations are used for extended periods without adequate cooling, their high temperature slows down charging power, thus prolonging charging time. Therefore, by considering the cumulative number of times a charging station has been used that day before the end of charging, the cumulative usage time, and the idle time from the end of charging to the customer's inquiry, the optimal idle charging station can be selected, further improving charging efficiency. This method also effectively prevents some charging stations in the parking lot from being reused repeatedly while others remain underutilized. Since repeatedly used charging stations have shorter lifespans than less frequently used ones, allowing users to know the cumulative number of times a charging station has been used that day before the end of charging, the cumulative usage time, and the idle time from the end of charging to the customer's inquiry, allows for more even usage of all charging stations in the parking lot. This facilitates large-scale maintenance and management of charging stations, avoiding sequential maintenance of charging stations from the same batch, which is detrimental to parking lot management.

[0037] Furthermore, the availability of charging stations in parking lots also includes the charging protocols compatible with the available charging stations, such as AC slow charging (GB / T 20234.2) and DC fast charging (GB / T 20234.3), as well as the compatibility range of the power and voltage of the available charging stations. Users can access this information through the parking lot management platform to know in advance whether available charging stations can charge their new energy vehicles. If the charging protocol is incompatible, even if the new energy vehicle's charging head can connect to the charging port, the charging station cannot interact with the vehicle, resulting in charging failure. Therefore, by publishing information such as the compatible charging protocols (AC slow charging (GB / T 20234.2) and DC fast charging (GB / T 20234.3)) and the compatibility range of the power and voltage of the available charging stations on the parking lot management platform, users can accurately know whether available charging stations in the parking lot are compatible with their new energy vehicles, thus ensuring successful charging and effectively avoiding situations where available charging stations cannot be used for charging.

[0038] The usage status of the parking lot charging piles also includes the amount of electricity being charged by the charging piles currently in use for the new energy vehicles being charged, and the estimated time for the charging to be completed.

[0039] If a parking lot has no available charging stations, it can be planned in advance by considering the estimated time for the new energy vehicle to complete charging or which charging stations will be available at that time.

[0040] Example 3 This embodiment is a further improvement on embodiment 2, as detailed below: The formula for calculating the number of currently available charging stations is N=MX*S; where N is the number of currently available charging stations, M is the number of currently available charging stations, X is the average number of vehicles entering the parking lot, and S is the reservation duration.

[0041] Since the vehicles entering the parking lot include gasoline vehicles and electric vehicles, and electric vehicles include those that need charging and those that do not, the number of currently available charging stations calculated based on the average traffic flow entering the parking lot is taken as the minimum number. This effectively ensures that after making a reservation, users can find an available charging station to use when they arrive at the parking lot within the reserved time.

[0042] Example 4 This embodiment is a further improvement on embodiment 3, as detailed below: The parking management platform pushes the remaining reservation time to the terminal at preset intervals.

[0043] Users are informed of the remaining reservation time in a timely manner, enabling them to arrive at the parking lot within the reserved time slot.

[0044] Example 5 A charging pile status query system based on the Internet of Things, including a server and a terminal; The server is used to receive and store the parking lot address and the corresponding query system QR code; The terminal is used to log in to the server to search for parking lots near the destination and obtain the corresponding query system QR code; it is also used to scan the query system QR code to log in to the corresponding parking lot management platform and obtain the usage status of the parking lot charging piles.

[0045] By connecting various parking lot management platforms together, users can first search for parking lots near their destination using electronic devices such as mobile phones and tablets before traveling. They will then obtain a QR code for the parking lot query system, scan it to log in to the corresponding parking lot management platform, and check the availability of charging stations. Users can access detailed information about the charging station availability before departure. If no charging stations are available at the selected parking lot, users can continue to check the availability of charging stations in other parking lots near their destination. This allows users to know the availability of charging stations near their destination before traveling, enabling them to choose a parking lot with sufficient available charging stations. This effectively avoids long waits at parking lots where no charging stations are available, or vehicles running out of power and becoming stranded on the road while trying to find another parking lot. Because this solution allows new energy vehicle users to check the availability of charging stations near their destination before traveling, and if no available charging stations are found near their destination, they can choose to use parking lots further away with available charging stations. This effectively increases the utilization rate of relatively remote or newly built charging stations, avoids resource idleness, and improves the user's travel experience.

[0046] Example 6 This embodiment is a further improvement on embodiment 5, as detailed below: The usage status of the parking lot charging piles includes the number of currently available charging piles and the number of currently available charging piles for reservation.

[0047] The system provides parameters on the number of available charging stations for users to refer to when they are going to a parking lot. Users can also reserve charging stations before going to the parking lot to avoid the situation where available charging stations are used by vehicles entering during the journey, resulting in no charging stations available when users arrive at the parking lot. In practice, the number of available charging stations refers to those that are not in use and have not been reserved. Further information on the usage status of parking lot charging stations includes the time when an idle charging station completes charging and the duration of use. By setting a timer on the parking lot charging station, the timer starts when the charging station begins charging. That is, when the charging head is connected to the charging port of the new energy vehicle, the timer switch set on the charging head is triggered, and the timer starts counting. When the user separates the charging head from the charging port of the new energy vehicle after charging is completed, the timer switch is triggered again, and the timer stops counting. This records the usage time of the charging station, and the timer also records the time when it stops counting. When a user finds available charging stations through the parking management platform, they can see the station's total usage count and duration before the end of the day, as well as the idle time from the time the user inquired about the station. This idle time is essentially the cooling-off period for the charging station. Therefore, users can use this information to select the optimal available charging station when there are enough available stations. If a charging station has been used for a long time without sufficient cooling, its high temperature will reduce charging power and prolong charging time. Therefore, by referring to the charging station's total usage count and duration before the end of the day, and the time from the time the user inquired about the station, the idle time of the charging station is... Knowing when to select the optimal idle charging station can further improve charging efficiency. This method also effectively prevents some charging stations in a parking lot from being reused repeatedly while others remain underutilized. Since reused charging stations have shorter lifespans than less frequently used ones, knowing the cumulative number of times a charging station has been used that day before the end of charging, the cumulative usage time, and the idle time from the end of charging to the time the customer inquires allows users to select the optimal idle station. This ensures a more even distribution of usage across all charging stations in the parking lot, facilitating large-scale maintenance and management of charging stations and preventing sequential maintenance of charging stations from hindering parking lot management.

[0048] Furthermore, the availability of charging stations in parking lots also includes the charging protocols compatible with the available charging stations, such as AC slow charging (GB / T 20234.2) and DC fast charging (GB / T 20234.3), as well as the compatibility range of the power and voltage of the available charging stations. Users can access this information through the parking lot management platform to know in advance whether available charging stations can charge their new energy vehicles. If the charging protocols are incompatible, even if the new energy vehicle's charging head can connect to the charging port, the charging station cannot interact with the vehicle, resulting in charging failure. Therefore, by publishing information such as the compatible charging protocols (AC slow charging (GB / T 20234.2) and DC fast charging (GB / T 20234.3)) and the compatibility range of the power and voltage of the available charging stations on the parking lot management platform, users can accurately know whether available charging stations in the parking lot are compatible with their new energy vehicles, thus ensuring successful charging and effectively avoiding situations where available charging stations cannot be used for charging.

[0049] The usage status of the parking lot charging piles also includes the amount of electricity being charged by the charging piles currently in use for the new energy vehicles being charged, and the estimated time for the charging to be completed.

[0050] If a parking lot has no available charging stations, you can find out in advance which charging stations will be available at the corresponding time based on the estimated time it takes for the new energy vehicle to complete charging, thus allowing you to make plans ahead of time.

[0051] The formula for calculating the number of currently available charging stations is N=MX*S; where N is the number of currently available charging stations, M is the number of currently available charging stations, X is the average number of vehicles entering the parking lot, and S is the reservation duration.

[0052] Since the vehicles entering the parking lot include gasoline vehicles and electric vehicles, and electric vehicles include those that need charging and those that do not, the number of currently available charging stations calculated based on the average traffic flow entering the parking lot is taken as the minimum number. This effectively ensures that after making a reservation, users can find an available charging station to use when they arrive at the parking lot within the reserved time.

[0053] The terminal is also used to receive the remaining reservation time pushed by the parking management platform at preset intervals.

[0054] Users are informed of the remaining reservation time in a timely manner, enabling them to arrive at the parking lot within the reserved time slot.

[0055] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
