Detailed ways

In order to make those skilled in the art better understand the technical solutions in one or more embodiments of the present specification, in the following one or more embodiments of the present specification, in one or more embodiments of the present specification, The technical solutions are described clearly and completely, and it is obvious that the described embodiments are only a part of the embodiments, rather than all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on one or more embodiments of the present disclosure without departing from the inventive scope are intended to be within the scope of the disclosure.

With the increase in the number of shared vehicles (for example, shared bicycles, shared electric vehicles), in some places, a plurality of parking areas are divided for the vehicles, and the users of the vehicles can park the vehicles in the parking area after the end of use. Avoid chaos and disruption affect life management. For example, a parking area dedicated to shared vehicle parking may be provided at the subway station, or a shared vehicle parking area may be drawn at the door of the living quarter, or a parking area may be divided on the outdoor road of the office.

For the manager of the shared vehicle, whether the shared vehicle is parked in the parking area according to regulations requires understanding and formulating further management strategies. The vehicle positioning method provided by one or more embodiments of the present specification can help the manager to more accurately determine whether the shared vehicle is parked in the parking area. In addition, since the parking of the shared vehicle is restricted by the parking area, the image of the parking area may be referred to as an "electronic fence" to restrict the user of the shared vehicle from parking the vehicle into the area corresponding to the fence. The vehicle positioning method of the present disclosure may be to achieve vehicle positioning by an electronic fence system.

1 illustrates an implementation of an electronic fence system. As shown in FIG. 1, the electronic fence system can include three devices: a signal transmitting device 11, a vehicle positioning device 12, and a vehicle management device 13.

The signal transmitting device 11 can be disposed on the shared vehicle. Taking the shared bicycle as an example in FIG. 1 , it can be understood that other vehicles such as a shared electric vehicle and a shared automobile can also be applied to the system. In one example, the signal transmitting device 11 may be a Bluetooth signal transmitting device for transmitting a Bluetooth signal for Bluetooth positioning of the shared bicycle in accordance with the Bluetooth signal. In the example of using other short-range positioning methods (for example, UWB (Ultra Wide Band) technology, ZigBee), the signal transmitting device 11 may also be a device for transmitting other short-range positioning signals. Example to describe.

The signal transmitting device 11 can broadcast two kinds of data, one is a vehicle identification of a shared bicycle, that is, a vehicle ID that uniquely identifies the vehicle, and the other data is a Bluetooth signal. The broadcast of the above two kinds of data may be a periodic broadcast, or may be a broadcast of the departure data when the bicycle lock is shared.

Wherein, the vehicle positioning device 12 can be disposed in a parking area for parking the vehicle, the parking area has its own area identification, and the vehicle parked in the area is not limited, for example, the user of the vehicle ends at a certain parking area. For the car, park the car in the parking area.

The vehicle positioning device 12 can be configured to receive the vehicle identification and the Bluetooth signal transmitted by the signal transmitting device 11, and can also perform a positioning operation on the vehicle according to the Bluetooth signal by using a Bluetooth positioning algorithm to obtain location information of the vehicle. In one example, the location information can be the distance between the shared bicycle and the vehicle positioning device 12. Next, the vehicle positioning device 12 can also transmit the area identification of the parking area in which it is located, the vehicle identification of the vehicle, and the calculated vehicle position information to the vehicle management device 13.

As in the example of FIG. 1, the vehicle management device 13 can be placed in the cloud. In other examples, the vehicle management device 13 may be located at other locations as well. The vehicle management device 13 can determine, according to the location information transmitted by the vehicle positioning device 12, whether the vehicle corresponding to the vehicle identification is parked in the parking area corresponding to the area identification. For example, if the location information is the distance between the vehicle and the vehicle positioning device 12, then if the distance is within a predetermined distance threshold, it may be determined that the vehicle is parked in the parking area.

In the vehicle positioning method of one or more embodiments of the present specification, the positioning of the vehicle parking can be realized by the electronic fence system illustrated in FIG. 1 above, and it is determined whether the vehicle is parked in a predetermined parking area. The execution process of the positioning method will be described by the flowchart shown in Fig. 2 as follows.

In step 200, the signal transmitting device on the shared bicycle broadcasts the data.

The method of the present example is described by taking the shared bicycle in FIG. 1 as an example, but is not limited thereto. A shared bicycle can be an internet bike that starts riding and billing through a mobile phone scan code. A signal transmitting device can be provided on the shared bicycle, and the device can transmit a short-range positioning signal, such as a Bluetooth signal. In other examples, the signal transmitting device can also transmit signals such as UWB for vehicle positioning.

The signal transmitting device may broadcast data when the user triggers the parking action. For example, after the user finishes using the vehicle, the shared bicycle may be triggered to enter the locked state by the action of locking or the like, and the signal transmitting device starts broadcasting data. The broadcasted data may include a vehicle identification that uniquely identifies the vehicle, and the vehicle management device of the subsequent cloud may identify the corresponding vehicle by the vehicle identification; the broadcasted data may further include a Bluetooth signal. If there is a parking area (which may be called an electronic fence) near the user's parking, the Bluetooth signal may be received by the vehicle positioning device in the parking area and thereby identify whether the vehicle is parked in the parking area; otherwise, if there is no parking area near the parking area The cloud can think that this parking is free parking.

In step 202, the vehicle positioning device of the parking area performs a positioning operation on the vehicle according to the positioning signal to obtain position information of the vehicle.

In this example, the positioning operation of the shared bicycle can be performed by using a Bluetooth positioning algorithm, which is to know the distance of the measured shared bicycle by sensing the signal strength of the vehicle positioning device receiving the Bluetooth signal to achieve positioning. For example, the vehicle positioning device can measure the received signal strength of the received Bluetooth signal, and according to the received signal strength, use a Bluetooth positioning algorithm to perform a positioning operation on the vehicle to obtain a distance between the vehicle and the vehicle positioning device. Generally, the stronger the received signal, the closer the vehicle is to the parking area.

The signal receiving module for receiving the Bluetooth signal in the vehicle positioning device may be configured with at least one. Exemplarily, three signal receiving modules can be set to more accurately locate the position of the shared bicycle through the three-point positioning algorithm, and the accuracy can be in the range of 3 to 5 meters.

In step 204, the vehicle location device of the parking area transmits the location information to the vehicle management device.

In this step, the vehicle positioning device may transmit the area identification of the parking area, the vehicle identification of the shared bicycle, and the position information calculated in step 202 to the vehicle management device in the cloud. The area identifier may be information for uniquely identifying the parking area, for example, geographic location information such as latitude and longitude of the parking area, or may also be an ID of the parking area.

In one or more examples of the present specification, the location information may be the distance between the shared bicycle and the vehicle locating device. In other examples, the location information may also be a determination result of determining whether the bicycle is parked in the parking area. After transmitting the above information to the vehicle management device in the cloud, the vehicle management device can perform parking management and further business activities, for example, rewarding parking for a bicycle in the parking area, or punishing the behavior that the parking is not in the parking area, as described in the following steps. .

In step 206, the vehicle management device in the cloud determines whether the shared bicycle is parked in the parking area.

In this step, the vehicle management device may acquire a distance threshold corresponding to the area identifier according to the received area identifier. Different areas identify the corresponding parking area, and the distance threshold may be different. For example, in the parking area near the subway station, the demand for sharing bicycles is generally larger, and there are more shared bicycles parked, so the area of this parking area is also larger. The distance threshold can be set larger. For another example, the parking area at the entrance of the residential area can be relatively small, so the distance threshold can be set slightly smaller.

The cloud may store a correspondence between the area identifier of each parking area and a distance threshold, and obtain a distance threshold corresponding to the identifier of the area according to the correspondence. The vehicle management device may compare the distance between the received vehicle and the vehicle positioning device with the distance threshold. If the distance is within the range of the distance threshold, it may be determined that the shared bicycle corresponding to the vehicle identifier stops at the parking area corresponding to the area identifier. in.

In step 208, the vehicle management device in the cloud performs corresponding service processing according to the location of the vehicle.

For example, the vehicle management device may award or punish the vehicle user accordingly depending on whether the vehicle is parked in the parking area. For example, a shared bicycle parked in a parking area can give feedback to the user, red envelopes, and there is no incentive activity for bicycles that are not parked in the parking area.

The vehicle positioning method of the present example can achieve positioning of the vehicle by installing a transmitting device for transmitting a close positioning signal on the vehicle and cooperating with a vehicle positioning device disposed in the parking area to achieve close positioning of the vehicle. Higher accuracy and more accurate vehicle positioning; and, when using Bluetooth positioning, can make power consumption lower. The method can help the shared vehicle operator to constrain the vehicle user to park the vehicle into the designated parking area, and solve the problem that the shared vehicle is randomly stopped and placed.

In order to implement the vehicle positioning method described above, one or more embodiments of the present specification also provide a vehicle positioning apparatus.

The positioning operation module 32 is configured to perform positioning operations on the vehicle according to the positioning signal to obtain position information of the vehicle; the positioning operation module may include an embedded CPU system and a positioning algorithm.

The network transceiver module 33 is configured to send the location information, the vehicle identifier, and the area identifier of the parking area to the vehicle management apparatus, so that the vehicle management apparatus determines, according to the location information, whether the vehicle corresponding to the vehicle identifier is stopped.
