Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clearly understood, the embodiments of the present disclosure are described in further detail below with reference to the accompanying drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the embodiments of the disclosure and that no limitation to the embodiments of the disclosure is intended.
First, before specifically describing the technical solution of the embodiment of the present disclosure, a technical background or a technical evolution context on which the embodiment of the present disclosure is based is described. At present, a shared vehicle generally uses satellite positioning and Bluetooth spikes to realize fixed-point parking, and then uses a magnetometer and an angle/acceleration sensor to realize directional parking by using a related inertial navigation algorithm. However, the positioning accuracy of satellite positioning is only about 10 meters in an open environment, and therefore the redundancy of the electronic fence at the station location needs to be greater than 10 meters to ensure normal vehicle returning of a user. And bluetooth spike technique can promote positioning accuracy to about 1 meter, can have certain improvement to the fixed point parking, but bluetooth signal easily receives the interference, and human or metal shelters from and all can influence bluetooth positioning accuracy, also is difficult to accomplish accurate parking, and bluetooth spike cost is higher in addition, and a position just need be laid every 1 ~ 2 meters in general parking spot, and the spike still needs built-in battery, and the battery also needs regular replacement to be maintained, and the total cost price is too big for promoting the cost. Although magnetometers can provide reliable, low cost and high precision orientation by measuring the earth's magnetic field. However, the output of the magnetometer is distorted by the self and the ambient magnetic field environment to generate errors, such as offset errors, scale factor errors, non-orthogonal errors, installation errors, hard magnetic and soft magnetic errors, and the like, and the errors change along with the change of the environment, so that the calibration difficulty is high, and the use of an actual sharing bicycle and an electric bicycle is not facilitated; the angle/acceleration sensor can realize directional navigation by using a related inertial navigation algorithm, a signal transceiver is not required to be arranged in the angle/acceleration sensor, the system is not influenced by environmental change, signal blocking and the like, but the problems of accumulated error, higher cost and the like exist, the practicability of the system is greatly weakened, and therefore the problem that a user cannot accurately perform fixed-point directional parking by the conventional fixed-point directional parking method is solved. In view of this, how to solve the problem that the user cannot accurately perform fixed-point directional parking becomes a problem to be solved urgently at present. In addition, it should be noted that, from the problem of determining that the user cannot accurately perform fixed-point directional parking and the technical solution described in the following embodiments, the applicant has paid a lot of creative efforts.
The following describes technical solutions related to the embodiments of the present disclosure with reference to a scenario in which the embodiments of the present disclosure are applied.
Referring to fig. 1, a coil detector 10 is shown, the coil detector 10 comprising: a signal generator 101, a signal detector 102 and at least one first coil 103; the signal generator 101 is connected with the signal detector 102; the signal generator 101 is used for sending an induction signal when a car returning request signal is acquired; the signal detector 102 is used for detecting feedback information generated after the induction signal is interfered by the magnetic field, so that the sharing equipment executes the returning operation according to the feedback information; the magnetic field interference is generated by mutual inductance between the first coil and the second coil of the parking pile.
The coil detector 10 may be disposed inside the shared device, below the shared device vehicle body, or on the handle of the shared device, and the present embodiment does not limit the disposition position of the coil detector 10. Alternatively, the sharing device may be a non-motorized or motorized vehicle such as a bicycle, electric bicycle, scooter, motorcycle, or the like.
Specifically, when the signal generator 101 acquires a return request signal of the sharing device, it sends an induction signal, a first coil included in the coil detector 10 can generate mutual inductance with a second coil of the parking pile to generate magnetic field interference, the induction signal sent by the signal generator 101 is subject to the magnetic field interference to change, and feedback information is generated, and the signal detector 102 can detect the feedback information generated after the induction signal is subject to the magnetic field interference, so that the sharing device can execute a return operation according to the feedback information. Generally, when the sharing device performs a car returning operation, certain parking requirements need to be met, for example, when the sharing device meets fixed-point and/or directional parking, the sharing device can perform the car returning operation, and then the sharing device can determine whether the sharing device meets the fixed-point and/or directional parking according to the feedback information detected by the signal detector 102, and perform the car returning operation again in case of the fixed-point and/or directional parking. For example, the feedback information generated after the signal detector 102 detects that the induction signal is interfered by the magnetic field may include current information, and the sharing device may determine whether the sharing device is parked in a parking pile according to the detected current information, and perform a returning operation if the sharing device is parked in the parking pile; or, the feedback information generated after the signal detector 102 detects that the induction signal is interfered by the magnetic field may include phase information, and the sharing device may determine, according to the detected phase information, whether the sharing device parks in the parking pile according to a specified parking direction, and if so, perform a returning operation; still alternatively, the feedback information generated after the signal detector 102 detects that the induction signal is interfered by the magnetic field may include current information and phase information, and the sharing device may determine whether the sharing device is parked in the parking pile and whether the sharing device is parked in the parking pile according to the specified parking direction according to the detected current information and phase information, and perform a returning operation if the sharing device is parked in the parking pile and the parking is performed in the parking pile according to the specified parking direction.
Alternatively, the sensing signal sent by the signal generator 101 may be a sinusoidal waveform signal, or may be a signal with other waveforms. Optionally, when acquiring the car return request signal, the signal generator 101 may send the sensing signal according to a preset time interval, or send the sensing signal in real time.
Alternatively, the first coils 103 included in the coil detector 10 may be arranged in the coil detector 10 at predetermined intervals. Alternatively, the first coil 103 may be an active coil. Alternatively, the first coil 103 may be a PCB coil or a metal coil. It can be understood that, since the first coil 103 is an active coil, optionally, resistors with different sizes may be loaded on two ends of the first coil 103 to provide power for the first coil 103. Optionally, the number of turns of the first coil 103 may be set according to an interval between adjacent parking piles of the parking spot, if the interval between adjacent parking piles of the parking spot is larger, the number of turns of the first coil 103 is larger, and if the interval between adjacent parking piles of the parking spot is smaller, the number of turns of the first coil 103 is smaller. It is understood that the coil detector in this embodiment includes the first coil 103 for generating mutual inductance with the second coil of the parking pile to generate magnetic field interference, and therefore, the first coil 103 only needs to be capable of generating mutual inductance with the second coil of the parking pile, and the number and type of the first coil 103 are not limited in this embodiment.
The coil detector comprises a signal generator, a signal detector and at least one first coil; the signal generator is connected with the signal detector, the signal generator can send induction signals when obtaining a vehicle returning request signal, the first coil and the second coil of the parking pile generate mutual inductance to generate magnetic field interference, the signal detector can detect feedback information generated after the induction signals are interfered by the magnetic field, the sharing equipment can execute vehicle returning operation according to the feedback information detected by the signal detector, and certain guidance effect can be played on vehicle returning of the sharing equipment through the feedback information, so that the sharing equipment can be ensured to accurately perform fixed-point directional parking.
In a scenario where the signal detector 102 detects feedback information generated after the sensing signal is interfered by the magnetic field, the feedback information includes a current value generated after the sensing signal is interfered by the magnetic field and a waveform phase of the sensing signal after the sensing signal is interfered by the magnetic field, in an embodiment, as shown in fig. 2, the signal detector 102 includes a current sensor 1021, and the current sensor 1021 is configured to detect the current value and the waveform phase.
Specifically, the feedback information generated after the sensing signal detected by the signal detector 102 is interfered by the magnetic field includes a current value generated after the sensing signal is interfered by the magnetic field and a waveform phase of the sensing signal after the sensing signal is interfered by the magnetic field, and the signal detector 102 may detect the current value generated after the sensing signal is interfered by the magnetic field and the waveform phase of the sensing signal after the sensing signal is interfered by the magnetic field through the included current sensor 1021. Optionally, after the current sensor 1021 detects the current value generated by the magnetic field interference of the sensing signal, the waveform phase of the sensing signal after being interfered by the magnetic field may be detected through the detected current value, for example, if the current sensor 1021 detects that the current value generated by the magnetic field interference of the sensing signal is larger, the current sensor 1021 may determine that the waveform phase change amplitude of the sensing signal after being interfered by the magnetic field is larger, and if the current sensor 1021 detects that the current value generated by the magnetic field interference of the sensing signal is smaller, the current sensor 1021 may determine that the waveform phase change amplitude of the sensing signal after being interfered by the magnetic field is smaller, it is understood that the magnetic field interference generated by the same kind of coils is the same, and further the waveform phase of the sensing signal tends to the same phase, and the magnetic field interference generated by the opposite kind of coils is different, so that the waveform phase of the sensing signal tends to different phases, if the waveform phase change amplitude of the induction signal after being interfered by the magnetic field is larger, the second coil of the parking pile can be determined to be the same type of coil, and if the waveform phase change amplitude of the induction signal after being interfered by the magnetic resonance is smaller, the second coil of the parking pile can be determined to be different types of coils. It is understood that if the larger the current value detected by the current sensor 1021 is, the stronger the reaction of the mutual inductance between the first coil 103 included in the coil detector 10 and the second coil of the parking pile is, the larger the number of the second coils of the parking pile can be determined; if the smaller the current value detected by the current sensor 1021 is, the weaker the reaction of the mutual inductance between the first coil 103 comprised by the coil detector 10 and the second coil of the parking pile is, the lower the number of second coils of the parking pile can be determined.
Alternatively, in another embodiment, in order to improve the efficiency of the current value generated by the magnetic field interference on the sensing signal and the waveform phase of the sensing signal after the magnetic field interference, as shown in fig. 3, the signal detector 102 may include a current sensor 1021 and a phase detector 1022, where the current sensor 1021 is used for detecting the current value; and a phase detector 1022 for detecting a phase of the waveform. Optionally, if the phase detector 1022 detects that the waveform phase of the induction signal after being interfered by the magnetic field is the first phase, it indicates that the second coil of the parking pile is the same kind of coil; if the phase detector 1022 detects that the waveform phase of the induction signal after being disturbed by the magnetic field is the second phase, it indicates that the second coil of the parking pile is the opposite type coil.
Further, the sharing device may determine that the second coil included in the parking pile is detected when the signal detector detects a current value generated by the magnetic field interference on the induction signal, and may further determine that the sharing device is parked in the parking pile; in addition, adjacent coils in the second coils included in the detected parking piles are determined to be different types of coils according to the waveform phase of the induction signals after being interfered by the magnetic field, so that the shared equipment can be determined to meet the requirement of directional parking, and the shared equipment can execute the returning operation under the condition that the shared equipment is determined to be parked in the parking piles and meets the requirement of directional parking.
In this embodiment, the current sensor included in the signal detector can detect the current value generated by the magnetic field interference of the sensing signal and the waveform phase of the sensing signal after the magnetic field interference, so that the structure of the signal detector is simpler, the current value generated by the magnetic field interference of the sensing signal and the waveform phase of the sensing signal after the magnetic field interference can be accurately detected, and the detection accuracy of the current value generated by the magnetic field interference of the sensing signal and the waveform phase of the sensing signal after the magnetic field interference is improved.
In some scenarios, it is necessary to amplify the induction signal transmitted by the signal generator 101 to increase the energy of the transmitted induction signal, and in one embodiment, as shown in fig. 4, the coil detector 10 further includes a power amplifier 104; the power amplifier 104 is connected to the signal generator 101 and the signal detector 102, respectively, and the power amplifier 104 is used for amplifying the sensing signal.
The power amplifier (power amplifier) refers to an amplifier that can generate maximum power output to amplify the energy of the transmitted sensing signal under a given distortion rate condition. Specifically, after the signal generator 101 transmits the induction signal, the induction signal may be amplified by the power amplifier 104 connected to the signal generator 101 to increase the energy of the transmitted induction signal, so that the signal detector 102 can more easily detect the feedback information generated after the induction signal is interfered by the magnetic field.
In this embodiment, the power amplifier can increase the energy of the sensing signal sent by the signal generator, so that the signal detector can more easily detect the feedback information generated after the sensing signal is interfered by the magnetic field, and further the sharing device can execute the returning operation according to the detected feedback information, thereby ensuring the accuracy of the returning operation executed by the sharing device.

Optionally, the parking piles 20 include at least two second coils 201 of opposite types, which may be arranged in the parking piles 20 at equal intervals according to a preset arrangement pitch. Optionally, the second coil may be a PCB coil, or may be a metal coil. Optionally, the first coil in the coil detector may include one coil or a plurality of coils, and the second coil 201 may generate magnetic field interference by mutual inductance with one coil in the first coil or generate magnetic field interference by mutual inductance with a plurality of coils in the first coil. For a detailed description of the embodiment that the sharing device realizes the parking of the sharing device according to the feedback information generated after the magnetic field interference, reference is made to the description in the embodiment corresponding to the coil detector, and this embodiment is not described herein again.
The parking pile provided by the embodiment comprises at least two second coils with opposite types, and the second coils can generate mutual inductance with the first coil in the coil detector to generate magnetic field interference, so that the shared equipment can accurately execute parking operation of the shared equipment according to feedback information generated after the magnetic field interference, and the accuracy of the parking operation executed by the shared equipment is improved.
