[0002] Shared electric bicycles are increasingly becoming the preferred means of transportation for short-distance travel, but after the large-scale popularization of shared electric bicycles, there are problems of random parking and disorderly placement.

[0003] However, this technical solution has the following defects: 1. The ground device sets a groove or a convex brow for accommodating the foot support, and there is no fixed connection between the electric bicycle foot support and the ground device. Not only does the ground device require a large area (the width and length of the ground device need to be greater than the width and length of the bottom of the foot support), but it also causes greater impact on pedestrians and other vehicles, has high cost and high damage rate, and lacks fixed connection, which makes the bicycle unstable and prone to falling; 2. The ground device needs to distinguish the left and right or up and down positions of the sensor (or inductor), which requires a higher position for placing the sensor in the ground device, and cannot adapt to more complex use environments; 3. The data calculation amount is large, the data calculation error rate is high, and the detection accuracy is low when detecting the directional parking of the vehicle, which not only slows down the vehicle returning speed, but also causes the vehicle to be unable to return or parked abnormally.

[0030] The e-bike compliance placement detection device, method, system and storage medium of the present application have the following advantages:

[0031] (1) There is only one passive radio frequency tag in the ground plate installed on the road surface, and the passive radio frequency tag does not need to distinguish left and right or up and down positions. Compared with the technical solution of the traditional ground device which adopts multiple sensors or needs to deploy sensors in left and right or up and down positions, not only can effectively reduce the length or width of the road surface ground plate, reduce the impact of the ground plate on pedestrians and other vehicles, reduce the cost and damage rate, but also effectively reduce the installation requirements of the sensors in the ground plate, improve the adaptability of the ground plate to the use scene.

[0032] (2) Through the structural design of the ground plate and the bottom of the foot support, the foot support is at different heights when placed in compliance and when placed non-compliance, effectively distinguishing the vertical distance between the reader and the tag when the foot support is placed in compliance and non-compliance, so as to judge whether the e-bike is placed in compliance according to whether the reader identifies the tag. Compared with the technical solution of the traditional ground device which needs multiple sensors to cooperate with the sensors in the vehicle to realize fixed-point and directional parking, not only can effectively reduce the complexity of data processing and improve the speed of vehicle identification, but also can effectively reduce the error rate of multiple data cooperation and improve the identification accuracy of fixed-point and directional parking.

[0033] (3) The edge of the ground plate is at the same horizontal height as the front surface of the ground plate, without the need for a convex brow. Compared with the technical solution of the traditional ground device which adopts a convex brow, not only can further reduce the impact of the ground plate on pedestrians and other vehicles, but also can effectively reduce the production and manufacturing difficulty of the ground plate, reduce the cost and damage rate.

[0034] (4) The foot support is supported by the embedded structure. Compared with the technical solution of the traditional ground device whose size needs to be larger than the size of the foot support bottom to accommodate the foot support, not only can further reduce the area of the ground plate and reduce the impact of the ground plate on pedestrians and other vehicles, but also can improve the stability of the vehicle placement and avoid the single vehicle from falling.

[0035] (5) According to the transmission power of the RFID reader, the length of the foot support bottom protrusion or the edge height of the ground plate is calculated, compared with the technical solution of the traditional ground device which needs multiple sensors to cooperate with the sensors in the vehicle to realize the fixed-point and directional parking, the detection accuracy of the single bicycle parking angle can be effectively improved, and the standardization of the single bicycle parking can be improved.

[0036] (6) The ground plate has a multi-level structure and triggers the transmission structure to move the RFID tag to the upper layer position of the ground plate level structure when the foot support is placed in compliance, compared with the traditional technical solution of multiple RFID tags fixed in the ground plate and realizing fixed-point and directional parking according to multiple sensors cooperating with the sensors in the vehicle, the requirements for the transmission power of the RFID reader and the deployment position of the RFID tag can be reduced, and the use scene adaptability of the ground plate can be effectively improved.

[0037] (7) The ground plate has a multi-level structure, and when the ground plate is not parked or the single bicycle is not placed in compliance on the ground plate, the RFID tag is in the lower layer position of the ground plate level structure, compared with the traditional technical solution of multiple RFID tags fixed in the ground plate and realizing fixed-point and directional parking according to multiple sensors cooperating with the sensors in the vehicle, not only can effectively reduce the error rate of directional data calculation and improve the probability of successful parking, but also effectively protect the RFID tag from being damaged.

[0038] (8) According to the vertical distance threshold and / or the receiving sensitivity of the reader and / or the radio frequency signal coverage range index of the reader and / or the feedback signal strength index of the tag, the transmission power of the RFID reader is calculated, compared with the traditional technical solution of calculating the transmission power only according to the distance between the reader and the ground plate, the more accurate reader transmission power is obtained from the distance, receiving sensitivity, signal coverage and signal attenuation, etc. Different ground plate structures and different compliance placement detection device use scenarios can be effectively adapted, and the detection error of the electric bicycle parking angle can be reduced, and the accuracy of the electric bicycle compliance placement detection can be improved.

[0045] The present application will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present application, but do not limit the present application in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present application. These all belong to the protection scope of the present application.

[0046] The electric bicycle compliance placement detection device according to the present embodiment comprises a ground plate installed on the road surface and an RFID reader installed on the bicycle foot support, and the ground plate internally deploys an RFID tag. When the foot support is placed in a set position, the electric bicycle is in a compliance placement state, and when the foot support is placed in other positions, the electric bicycle is in a non-compliance placement state. The set position is a space with latitude, longitude, direction and shape set on the ground plate, and the other positions have different latitude, longitude and / or direction and / or shape and / or height from the set position. The compliance placement refers to the deviation of the latitude and longitude and direction of the parked electric bicycle from the preset latitude and longitude and direction within a preset range. When the RFID reader can identify the RFID tag, it is determined that the foot support is in compliance placement, otherwise it is determined that the foot support is in non-compliance placement.

[0047] In the present embodiment, the preset latitude is the position of the set-point parking (the position of the ground plate in the present embodiment), and the preset direction is the directional parking (the forward direction of the ground plate in the present embodiment). In the compliance placement, the deviation of the latitude and longitude is not more than 0.1°, and the deviation of the direction angle is not more than ±10° (allowing the inclined placement within ±10° angle).

[0048] In a preferred embodiment, the ground plate has an overall shape of an ellipse or a rectangle or a circle or any other irregular shape.

[0049] The set position comprises a ground plate recessed space accommodating the foot support bottom protruding part and / or a ground plate protruding space accommodating the foot support bottom recessed part. The ground plate protruding space and / or the ground plate recessed space have axial asymmetry (in the present embodiment, according to the direction of the foot support compliance placement, the ground plate protruding space and / or the ground plate recessed space have asymmetry along the horizontal axis), and the position of the foot support bottom recessed part or protruding part corresponds to the position of the ground plate protruding space or recessed space.

[0050] The raised space of the floor plate is any one or a combination of multiple types of spherical, hemispherical, arc-shaped, cylindrical, conical, cubic, rectangular, parallelogram, rhomboid, polygonal, spiral, stepped, or irregularly shaped protrusions that match the recessed part at the bottom of the foot support; the recessed space of the floor plate is any one or a combination of multiple types of spherical, hemispherical, arc-shaped, cylindrical, conical, cubic, rectangular, parallelogram, rhomboid, polygonal, spiral, stepped, or irregularly shaped recesses that match the raised part at the bottom of the foot support.

[0051] As one embodiment of this invention, the schematic diagram of the land sign structure is as follows: Figure 1 As shown in the diagram, the bottom structure of the foot support is as follows: Figure 2 As shown, the signpost 11 is cylindrical in shape, and the recessed space 111 is also cylindrical, meaning it is a designated location with set latitude, longitude, direction, and shape. The position of the recessed space is offset from the lateral central axis of the signpost 11. The recessed space 111 is used to accommodate the bottom protrusion 121 of the foot support 12. The bottom protrusion 121 of the foot support is a cylindrical protrusion that matches the recessed space of the signpost. When the foot support 12 is properly positioned, the protrusion 121 of the foot support can be completely embedded into the recessed space 11. 1. At this time, the vertical distance between the RFID tag 113 in the floor sign and the RFID reader 122 on the foot support is equal to the sum of the thickness of the floor sign shell and the thickness of the foot support shell. When the foot support 12 is not placed in accordance with regulations, the protrusion 121 of the foot support will not be embedded in the recessed space 111 of the floor sign. At this time, there is a gap between the foot support 12 and the front of the floor sign 11. The vertical distance between the RFID tag 113 in the floor sign and the RFID reader 122 on the foot support is greater than the sum of the thickness of the floor sign shell and the thickness of the foot support shell.

[0052] In a preferred embodiment, the degree of dimensional correlation between the recessed space of the parking sign and the protruding part at the bottom of the kickstand, or the degree of dimensional correlation between the protruding space of the parking sign and the recessed part at the bottom of the kickstand, is calculated based on the compliant parking direction of the bicycle. As one embodiment of this approach, such as... Figure 1 The dimensions of the recessed space 111 shown are slightly larger than those of the floor plan. Figure 2 The dimensions of the protrusion 121 at the bottom of the support shown represent the degree of dimensional correlation, ensuring that the protrusion fits perfectly into the recessed space 111 of the floor sign when the support is placed correctly. However, the protrusion 121 cannot fit into the recessed space 111 of the floor sign when the latitude and longitude of the support deviates from the set latitude and longitude by more than 0.1° and / or when the angle of the parking direction deviates from the set direction by more than ±10°.

[0053] A diagram illustrating the relationship between the footrest and the floor tile when placed in compliant and non-compliant configurations is shown below. Figure 3 As shown.

[0054] In a preferred embodiment, the length of the protrusion of the foot support bottom is calculated according to the transmitting power of the RFID reader. As an embodiment of this example, the length of the protrusion of the foot support bottom is positively correlated with the transmitting power of the RFID reader, as shown in the placement relationship Figure 3 . The length of the unembedded part is represented by variable f, and the transmitting power of the RFID reader is represented by variable p. The length f of the protrusion of the foot support bottom is calculated as f = e1·p + e2·p2 + e3, where e1, e2 (e2 > 0), e3 are calculation coefficients obtained through prior training. e2

[0055] In a preferred embodiment, the edge of the ground plate is at the same level as the front surface of the ground plate.

[0056] In another preferred embodiment, the edge of the ground plate is higher than the front surface of the ground plate; the height of the edge is calculated according to the transmitting power of the RFID reader. As an embodiment of this example, the height of the edge is positively correlated with the transmitting power of the RFID reader. The height of the edge is represented by variable q, and the transmitting power of the RFID reader is represented by variable p. The height q of the edge is calculated as q = k1·p + k2·p2 + k3, where k1, k2 (k2 > 0), k3 are calculation coefficients obtained through prior training. k2

[0057] In a preferred embodiment, the width of the ground plate is smaller than the width of the foot support bottom.

[0058] In a preferred embodiment, the protrusion 121 of the foot support bottom is embedded in the recessed space 111 of the ground plate, so that the foot support is fixed to the ground plate without the need for other connecting structures between the foot support and the ground plate.

[0059] In another preferred embodiment, the side surface of the recessed space 111 of the ground plate has a connecting structure 112 for fixing the protrusion 121 of the foot support bottom in the recessed space 111 of the ground plate. The connecting structure 112 includes any one or a combination of multiple types of fixing connecting structures, such as a buckle structure, a latch structure, a protrusion extrusion structure, a magnetic fixing structure, etc. As shown in the ground plate connecting structure 112 Figure 1 , which is a protrusion extrusion structure.

[0063] In this embodiment, a vertical distance threshold is set in advance to distinguish between the e-bike foot support compliant placement and the e-bike non-compliant placement (the deviation of the latitude and longitude of the foot support placement from the set latitude and longitude exceeds 0.1°, and the deviation of the direction angle of the foot support placement from the set square exceeds ±10°, usually the foot support is placed on the ground sign in the opposite direction or at an angle, or not placed on the ground sign) of the RFID reader and the RFID tag (usually the vertical distance threshold is slightly larger than the vertical distance between the RFID reader and the RFID tag when the e-bike foot support is placed compliantly). For example, when the e-bike foot support is placed compliantly, the vertical distance between the RFID reader and the RFID tag is 0.8 cm (the sum of the thickness of the ground sign groove and the thickness of the foot support lower sleeve), and when the e-bike foot support is placed non-compliantly, the vertical distance between the RFID reader and the RFID tag is 1 cm, then the vertical distance threshold is in the range of 0.8 cm to 1 cm, and here the vertical distance threshold r = 0.85 cm.

[0065] wherein the vertical distance threshold is the vertical distance threshold r calculated in the above embodiments; the receiving sensitivity of the RFID reader is represented by the variable m; the radio frequency signal coverage index of the RFID reader is the coverage degree of the range formed by the radio frequency signal emission direction of the RFID reader to the RFID tag (the ratio of the RFID tag area covered by the radio frequency signal of the reader to the total area of the tag), represented by the variable n; the feedback signal strength index of the tag is either the feedback signal strength generated after the tag is excited by the unit power radio frequency signal emitted by the reader or the ratio of the feedback signal strength generated after the tag is excited by the test signal emitted by the reader to the test signal strength, represented by the variable h.

[0090] Embodiment three, a correct placement detection method for an electric bicycle

[0091] The flow chart of the correct placement detection method for an electric bicycle in this embodiment is as shown in Figure 5 , which includes:

[0092] Step S01, calculating the vertical distance threshold. The vertical distance threshold is calculated according to the vertical distance between the RFID reader and the RFID tag when the bicycle foot prop is placed correctly and / or the vertical distance between the RFID reader and the RFID tag when the bicycle foot prop is not placed correctly;

[0093] Step S02, calculating the transmitting power of the RFID reader according to the vertical distance threshold and / or the receiving sensitivity of the reader and / or the radio frequency signal coverage index of the reader and / or the feedback signal strength index of the tag;

[0094] Step S03, when the e-scooter is returned, the RFID reader transmits the radio frequency signal according to the calculated transmitting power;

[0095] Step S04, after the RFID tag in the ground plate receives the radio frequency signal, it generates an induced current to excite a feedback signal and sends it to the RFID reader;

[0096] Step S05, the RFID reader acquires the signal feedback by the RFID tag;

[0097] Step S06, judging whether the foot support is placed in compliance according to whether the RFID reader can identify the RFID tag.

[0098] In this embodiment, in step S01, for the e-scooter compliance placement detection device described in any of the above embodiments, the vertical distance threshold r = 0.85 cm is obtained according to the calculation method in the above embodiments.

[0099] In step S02, the transmitting power p of the RFID reader is calculated according to the calculation method in any of Table A.

[0100] In step S03, when the e-scooter is returned, the RFID reader transmits the radio frequency signal according to the transmitting power calculated in step S02.

[0101] In another preferred embodiment, the RFID reader transmits the radio frequency signal at a certain frequency or the RFID reader transmits the radio frequency signal through physical triggering when the e-scooter is returned or the RFID reader transmits the radio frequency signal through sensor triggering when the e-scooter is returned or the RFID reader transmits the radio frequency signal after the person sends a return instruction through a mobile terminal when the e-scooter is returned.

[0102] In steps S04 and S05, if the vertical distance between the RFID tag in the ground plate and the RFID reader is less than 0.85 cm, the RFID tag in the ground plate can receive the radio frequency signal transmitted by the RFID reader and generate an induced current, the induced current excites a feedback radio frequency signal (the feedback radio frequency signal strength is positively correlated with the size of the induced current) and sends it to the RFID reader, the RFID reader can receive the signal feedback by the RFID tag, otherwise the reader cannot receive the signal feedback by the RFID tag or can only receive a very low intensity feedback signal (the feedback radio frequency signal strength is outside the receiving sensitivity of the RFID reader).

[0103] In step S06, if the signal strength of the feedback of the RFID tag received by the RFID reader is within the receiving sensitivity of the RFID reader, the RFID reader can identify the RFID tag information, thereby determining the compliant placement; if the RFID reader cannot receive the feedback of the RFID tag or the received feedback signal strength is outside the receiving sensitivity of the RFID reader, the RFID reader cannot identify the RFID tag information, thereby determining the non-compliant placement.

[0104] A computer readable storage medium of an embodiment of the present application stores a computer program for electronic data exchange, wherein the computer program causes a computer to execute the method of any of the above embodiments.
