[0074] Figure 1 A flow chart of a shared electric vehicle unlocking method based on NFC technology of the present invention is shown;

[0075] Figure 2 A block diagram of a shared electric vehicle unlocking system based on NFC technology of the present invention is shown. DETAILED DESCRIPTION

[0076] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0077] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0078] Figure 1 A flow chart of a shared electric vehicle unlocking method based on NFC technology of the present invention is shown.

[0079] like Figure 1 As shown, the present invention discloses a shared electric vehicle unlocking method based on NFC technology, comprising:

[0080] S101, after the user terminal opens a preset applet or app on the mobile terminal, obtains a distance value between the mobile terminal and a preset NFC tag;

[0081] S102, if the distance between the mobile terminal and the preset NFC tag is less than a preset first distance threshold, extracting vehicle information on the preset NFC tag;

[0082] S103, sending the vehicle information on the preset NFC tag to the mobile terminal for display, and triggering the unlocking window;

[0083] S104, when the user clicks on the unlocking window, the shared electric vehicle associated with the preset NFC tag will be unlocked.

[0084] According to an embodiment of the present invention, the operation and maintenance personnel write the vehicle information to the NFC (near field communication technology) tag through the operation and maintenance end, and install the NFC tag to the corresponding vehicle. After the user opens the preset applet or app, he approaches the NFC tag. When the distance value between the mobile terminal and the preset NFC tag is less than the preset first distance threshold, the data exchange between the two devices is realized through battery sensing, so as to obtain the vehicle information on the preset NFC tag, and display the vehicle information on the preset NFC tag on the mobile terminal, and pop up the unlocking window for the user to select and confirm.

[0085] According to an embodiment of the present invention, it also includes:

[0086] Based on a preset first time period, obtaining the power value of the shared electric vehicle in the current time period;

[0087] If the power value of the shared electric vehicle is less than the preset first power threshold, a low power value is displayed and the unlocking window is cancelled;

[0088] Calculate the difference between the power value of the shared electric vehicle in the current time period and the current value of the shared electric vehicle in the previous time period to obtain a first power difference;

[0089] If the first power difference is greater than the preset second power threshold, the power value on the preset NFC tag is revised according to the power value of the shared electric vehicle in the current time period.

[0090] It should be noted that the shared electric vehicle is equipped with an update system, which obtains the power value of the shared electric vehicle at every preset first time period. When the power value of the shared electric vehicle is less than the preset first power threshold, the corresponding shared electric vehicle will not be able to be used. Therefore, the unlocking window is cancelled to avoid the user from being unable to use the shared electric vehicle normally after opening the lock. In addition, when the first power difference of the shared electric vehicle in adjacent time periods is greater than the preset second power threshold, it means that the power value of the corresponding shared electric vehicle has changed. Therefore, the power value on the preset NFC tag is revised through the update system to avoid misleading consumers.

[0091] According to an embodiment of the present invention, it also includes:

[0092] Get the destination entered by the user and the current location;

[0093] According to the destination input by the user, the current location and the preset navigation system, the cycling route is obtained, and the corresponding cycling distance value is obtained;

[0094] Divide the corresponding riding distance value by the preset power consumption value per unit distance to obtain the predicted power consumption value of the current riding;

[0095] Subtract the power value of the shared electric vehicle in the current time period from the predicted power consumption value of the current ride to obtain a second power difference value;

[0096] If the second power difference is less than a preset third power threshold, a power shortage prompt message is triggered.

[0097] It should be noted that the user can also select the current shared electric vehicle by entering the destination before unlocking. When the second power difference is less than the preset third power threshold, it means that the shared electric vehicle selected by the current user may not have enough power to reach the destination. Therefore, the power shortage prompt information is triggered to avoid blind selection by the user and improve the service quality of shared electric vehicles.

[0098] According to an embodiment of the present invention, it also includes:

[0099] According to the vehicle information on the preset NFC tag, the operating range of the vehicle on the preset NFC tag is obtained;

[0100] Determine whether the destination input by the user is within the operating range of the vehicle on the preset NFC tag, and if not, generate out-of-use range information;

[0101] The out-of-use range information is sent to the user end for prompting.

[0102] It should be noted that shared electric vehicles have a specific operating range, and the preset NFC tag contains the operating range of the corresponding shared electric vehicle.

[0103] According to an embodiment of the present invention, after generating the out-of-use range information, the method further includes:

[0104] Get the distance value that is out of range;

[0105] The distance value beyond the usage range is multiplied by the preset cost coefficient to obtain the additional dispatching fee;

[0106] The additional dispatching fee is sent to the user terminal for display, and if the user terminal accepts the corresponding additional dispatching fee, an unlocking window is triggered;

[0107] If the user does not accept the corresponding additional scheduling fee, the unlocking window is triggered.

[0108] It should be noted that when the user's purpose exceeds the operating range of the corresponding shared electric vehicle, additional dispatching fees will be required, and the greater the distance value beyond the usage range, the higher the corresponding additional dispatching fees. The fee coefficient is a value greater than 0.

[0109] According to an embodiment of the present invention, after the triggering of the power shortage prompt information, the method further includes:

[0110] Extract the positioning information from the preset NFC tag;

[0111] According to the positioning information in the preset NFC tag and the preset shared electric vehicle database, other shared electric vehicles within the preset first range are extracted;

[0112] Extracting the power values ​​of other shared electric vehicles within a preset first range;

[0113] Calculate the difference between the predicted power consumption value of the current ride and the power values ​​of other shared electric vehicles within the preset first range in turn to obtain a third power difference value;

[0114] If there is a third power difference that is greater than or equal to a preset third power threshold, the shared electric vehicle corresponding to the third power difference is set as a candidate shared electric vehicle;

[0115] If there are multiple candidate shared electric vehicles, extract the location information of the candidate shared electric vehicles;

[0116] Compare and analyze the location information of the candidate shared electric vehicle with the location information in the preset NFC tag to obtain the location distance value;

[0117] Arrange the positioning distance values ​​in ascending order to obtain the minimum positioning distance value;

[0118] The alternative shared electric vehicle corresponding to the minimum positioning distance value is set as the optimal shared electric vehicle for the current user's riding, and a light prompt message is generated;

[0119] The lighting prompt information is sent to the optimal shared electric vehicle for lighting prompt.

[0120] It should be noted that there may be multiple shared electric vehicles in each parking area. When the mobile terminal held by the user triggers the low-battery prompt information, the location in the preset NFC tag is extracted, and the preset shared bicycle database is queried according to the location in the preset NFC tag to find all existing shared electric vehicles in the same parking area, and set them as other shared electric vehicles within the preset first range. When there is only one alternative shared electric vehicle, the light prompt information of the only alternative shared electric vehicle is triggered to let the user notice and make a selection.

[0121] According to an embodiment of the present invention, it also includes:

[0122] If there is no third power difference greater than or equal to the preset third power threshold, extracting the cycling route;

[0123] Based on the cycling route, obtain the range of the cycling route;

[0124] Determine whether there are other shared electric vehicles within the riding route. If so, extract the locations of other shared electric vehicles and set the other shared electric vehicles as initial candidate shared electric vehicles.

[0125] Compare and analyze the positioning information in the preset NFC tag and the position of the initial candidate shared electric vehicle to obtain the initial candidate distance difference;

[0126] Divide the initial candidate distance difference by the preset power consumption value per unit distance to obtain the power consumption value of the initial candidate distance;

[0127] Subtract the power value consumed by the initial candidate distance from the power value of the shared electric vehicle in the current time period to obtain a first power difference;

[0128] If the first power difference is less than the preset first power threshold, the initial candidate shared electric vehicle corresponding to the power value consumed by the initial candidate distance is deleted;

[0129] Extracting the positions of the remaining initial candidate shared electric vehicles;

[0130] Obtaining a remaining distance value according to the positions of the remaining initial candidate shared electric vehicles, the destination input by the user, and the preset navigation system;

[0131] Divide the remaining distance value by the preset power consumption value per unit distance to obtain the power consumption value of the remaining distance;

[0132] Extract the current power value of the remaining initial candidate shared electric vehicles;

[0133] Subtract the power value consumed by the remaining distance from the current power value of the remaining initial candidate shared electric vehicles to obtain a second power difference;

[0134] If the second power difference is greater than or equal to the preset first power threshold, the corresponding initial candidate shared electric vehicle is set as a formal candidate shared electric vehicle;

[0135] Sort the official candidate shared electric vehicles from near to far according to the current distance to the user, and extract the official candidate shared electric vehicle with the closest distance as the optimal candidate shared electric vehicle;

[0136] The best candidate shared electric vehicle and its corresponding location are sent to the mobile terminal for display.

[0137] It should be noted that the cycling route range is set by a preset range width base. For example, if the preset range width base is 10 meters, the cycling route is used as a benchmark, and the left and right ends of the cycling route are expanded 10 meters outward to set the corresponding cycling route range. When there is no third power difference greater than or equal to the preset third power threshold, it means that there is no shared electric vehicle in the parking area where the user is located that can directly reach the destination. Therefore, the conversion of shared electric vehicles can be achieved through standby shared electric vehicles. The user selects a shared electric vehicle in the current parking area, rides for a while, arrives at the position of the optimal standby shared electric vehicle, and then switches to the optimal standby shared electric vehicle to reach the final destination to complete the journey; when there is no formal standby shared electric vehicle, a prompt message indicating that the destination cannot be reached directly will be displayed on the mobile terminal.

[0138] According to an embodiment of the present invention, the step of obtaining the preset power consumption value per unit distance specifically includes:

[0139] Get historical riding data information of shared electric vehicles;

[0140] Divide the historical riding data of shared electric vehicles according to preset areas to obtain the historical riding data of shared electric vehicles in different areas;

[0141] Extracting a preset area that the cycling route passes through, and determining historical cycling data corresponding to the preset area that the cycling route passes through;

[0142] Extract the total riding distance value and the total power consumption value from the historical riding data of the preset area passed by the corresponding riding route;

[0143] Divide the total power consumption value by the total riding distance value to obtain the corresponding preset power consumption value per unit distance.

[0144] It should be noted that there are differences in traffic in different regions, which will affect the power consumption per unit distance of shared electric vehicles. For example, shared electric vehicles in areas with smooth traffic will definitely save more power than in areas with congested traffic. Therefore, the historical riding data of shared electric vehicles is divided by region to improve the accuracy of the preset power consumption per unit distance.

[0145] Figure 2 A block diagram of a shared electric vehicle unlocking system based on NFC technology of the present invention is shown.

[0146] like Figure 2 As shown, the second aspect of the present invention provides a shared electric vehicle unlocking system 2 based on NFC technology, including a memory 21 and a processor 22, wherein the memory stores a shared electric vehicle unlocking method program based on NFC technology, and the shared electric vehicle unlocking method program based on NFC technology is executed by the processor to implement the following steps:

[0147] After the user opens the preset applet or app on the mobile terminal, the distance value between the mobile terminal and the preset NFC tag is obtained;

[0148] If the distance between the mobile terminal and the preset NFC tag is less than a preset first distance threshold, extracting the vehicle information on the preset NFC tag;

[0149] Send the vehicle information on the preset NFC tag to the mobile terminal for display and trigger the unlocking window;

[0150] When the user clicks on the unlocking window, the shared electric vehicle associated with the preset NFC tag will be unlocked.

[0151] According to an embodiment of the present invention, it also includes:

[0152] Based on a preset first time period, obtaining the power value of the shared electric vehicle in the current time period;

[0154] Calculate the difference between the power value of the shared electric vehicle in the current time period and the current value of the shared electric vehicle in the previous time period to obtain a first power difference;

[0155] If the first power difference is greater than the preset second power threshold, the power value on the preset NFC tag is revised according to the power value of the shared electric vehicle in the current time period.

[0156] According to an embodiment of the present invention, it also includes:

[0157] Get the destination entered by the user and the current location;

[0159] Divide the corresponding riding distance value by the preset power consumption value per unit distance to obtain the predicted power consumption value of the current riding;

[0160] Subtract the power value of the shared electric vehicle in the current time period from the predicted power consumption value of the current ride to obtain a second power difference value;
