In contemporary society, with the development of science and technology and the progress of society, people have more and more travel demands, and the convenience of travel is more and more concerned. At present, vehicles are still important vehicles for people to go out, such as buses, taxis and the like, and great help is brought to people to go out. Particularly, under the condition of advocating green travel, public transport means mainly comprising buses are increasingly becoming the preferred travel means for the public. The bus at the present stage has the advantages of environmental protection, comfortable carriage environment and low traffic cost, but places with poor experience feeling exist. Specifically, at the present stage, there are various payment methods for passengers after getting on the bus, such as cash payment, two-dimensional code scanning payment, NFC payment, bus card swiping payment, and the like. The problems in the prior art are that the passenger needs to draw out the payment tool to be close to the designated area of the vehicle to realize payment, the payment is not automatic enough, the payment is not convenient and quick enough, and the convenience of payment, namely the convenience of vehicle charging, is influenced.

Exemplary method

As shown in fig. 1, an embodiment of the present invention provides a UWB-based vehicle control method, specifically, the method includes the following steps:

step S100, a target object is acquired based on UWB.

Among them, Ultra Wide Band (UWB) technology is a wireless carrier communication technology, which started from the pulse communication technology that was established in the 60 th century of 20 th. UWB technology utilizes ultra-wide baseband pulses with extremely wide frequency spectrum for communication, and is also known as baseband communication technology and wireless carrier communication technology. At present, the UWB technology is rapidly developed and widely applied, and positioning and ranging can be carried out based on the UWB technology. The target object is a user getting on the vehicle, i.e., a passenger. In this embodiment, when a user gets on a vehicle, the user can be positioned and range-measured based on the UWB technology, and a specific user (passenger) getting on the vehicle is determined as a target object.

And step S200, controlling the vehicle to send payment information to the mobile terminal of the target object so as to trigger the mobile terminal of the target object to carry out automatic payment based on the payment information.

The mobile terminal of the target object may be a smart phone of a boarding passenger, and may also be a smart band or other wearable smart terminal, which is not specifically limited herein. Specifically, when a user carries a plurality of mobile terminals, one of the terminals may be designated in advance to implement the above-described functions. The vehicle may be a vehicle with a toll demand, such as a bus or a taxi, and in this embodiment, the bus is taken as an example for specific description. When detecting that a user gets on the bus, the user who gets on the bus is used as a target object, the bus is controlled to send payment information to the smart phone of the target object, and the smart phone of the target object is triggered to automatically pay based on the received payment information. Because bus charges are typically fixed (e.g., charges of 2 dollars), the smart phone can automatically pay a preset fee based on the payment information. In another application scenario, when the vehicle is a taxi or other vehicle with unfixed fee, the passenger getting on the taxi can be used as the target object, and when the target object (passenger) gets off the taxi, the vehicle is controlled to send the corresponding fee charging information and the specific fee to the smart phone corresponding to the target object, so that the smart phone is triggered to automatically pay. The specific fee calculation mode may be set and adjusted according to actual requirements, and is not specifically limited herein.

As can be seen from the above, the UWB-based vehicle control method provided by the embodiment of the present invention obtains the target object based on the UWB; and controlling the vehicle to send payment information to the mobile terminal of the target object so as to trigger the mobile terminal of the target object to carry out automatic payment based on the payment information. Compared with the scheme that a passenger needs to draw out a payment tool (or cash) to be close to a designated area of a vehicle to realize payment in the prior art, the scheme of the invention automatically acquires the target object of getting on the vehicle based on UWB, controls the vehicle to send payment information to the mobile terminal of the target object to trigger the mobile terminal of the target object to automatically pay to finish automatic charging, does not need the passenger to draw out the payment tool (or cash) to be close to the designated area of the vehicle, enables the payment (and charging) to be more convenient and rapid, is favorable for improving the convenience of payment and the convenience of vehicle charging.

In this embodiment, as shown in fig. 2, the step S100 includes:

and S101, acquiring distance information of the distance object to be measured based on the UWB ranging technology.

And step S102, acquiring a target object based on the distance information and a preset distance threshold.

The object to be measured may be a user near the bus, for example, a user detectable by a UWB ranging device disposed on the bus. Specifically, the UWB distance measuring device provided on the bus locates the smart mobile terminal (in this embodiment, a smart phone) of the user to realize the location and distance measurement of the user. In this embodiment, the UWB ranging apparatus provided on the bus acquires distance information of nearby users based on the UWB ranging technology. The distance information may include a distance from the user (distance object to be measured) to the UWB ranging apparatus, and may also include a distance from the user to a predetermined position in the vehicle. The preset distance threshold is a preset distance for judging whether a user gets on the vehicle or not, and can be set and adjusted according to actual requirements, and is not specifically limited herein. For example, in the present embodiment, the distance threshold may be set to 0.5 m in advance, and when the distance from the user to the UWB ranging device is less than 0.5 m, the user is considered to be a boarding passenger as a target object.

UWB is a communication system with accurate positioning, and the positioning accuracy can reach centimeter level. Fig. 3 is a schematic diagram of a principle of UWB positioning according to an embodiment of the present invention, as shown in fig. 3, when UWB ranging is performed, a UWB transmitting device (including an antenna transmitting unit) and a UWB receiving device (including 3 antenna receiving units distributed in a "right-angle" shape) are needed, when the UWB transmitting device and the UWB receiving device are placed face to face (where the face-to-face placement refers to the face-to-face placement of antennas of two devices), two antenna receiving units (unit 1 and unit 2) in the horizontal direction of the receiving device can perform positioning in the horizontal direction on the transmitting device by calculating the time of flight and the angle of arrival of the antenna transmitting unit to the two antenna receiving units (unit 1 and unit 2), and similarly, two antenna receiving units (unit 2 and unit 3) in the vertical direction of the receiving device can perform positioning in the horizontal direction by calculating the time of flight and the angle of arrival of the antenna transmitting unit to the two antenna receiving units (unit 2 and unit 3), the transmitting device can be positioned in the vertical direction, so that the transmitting device can be positioned in three dimensions in space, and the distance between the transmitting device and the receiving device can be calculated. In order to be able to achieve precise positioning, the UWB antenna receiver, in particular the 3 receiver antenna elements of the receiver, must lie within 120 ° of the horizontal orientation of the transmitter, and must also lie within 120 ° of the vertical orientation of the transmitter.

In this embodiment, the smart phone of the user is a UWB transmitting device, which includes an antenna transmitting unit, the UWB receiving device is installed on the bus, and the UWB receiving device includes 3 UWB receiving antenna units distributed in a "right angle" shape. Fig. 4 is a schematic diagram of an installation position of a UWB receiving device of a bus according to an embodiment of the present invention, and as shown in fig. 4, in this embodiment, 3 UWB receiving devices are arranged in a front door area of the bus, and distances between every 2 UWB receiving devices are equal, so that coverage of each angle in the front door area of the bus is realized, and a smart phone can be positioned in any orientation. In this way, when a user gets on the vehicle, the user can be located by at least 1 of the 3 UWB receiving devices, regardless of which direction the user's smart phone is facing. As shown in fig. 4, the UWB receiving device B positions the smartphone in the horizontal direction and the vertical direction, and then calculates the distance from the smartphone to the UWB receiving device (which may be preset to 1 UWB receiving device out of 3 UWB receiving devices, for example, the UWB receiving device a), and when the calculated distance value is smaller than a preset distance threshold value (for example, 0.5 m), it may be considered that the user getting on the vehicle is detected, and the user is taken as a target object.

Specifically, in this embodiment, the step S200 includes: and controlling the vehicle to send payment information to the mobile terminal of the target object through the UWB communication technology so as to trigger the mobile terminal of the target object to automatically pay based on the payment information.

In this embodiment, the UWB receiving device provided in the vehicle may be controlled to directly send payment information to the smart phone of the target object through the UWB communication technology, thereby avoiding reestablishing communication connection and reducing the time required for payment. In the actual use process, the payment information may also be sent through other communication methods, which is not specifically limited herein.

Wherein, the payment information comprises a collection two-dimensional code. Further, the payment information may further include a fee. In practical use, the payment information may further include other information for payment, such as a collection account number, and is not limited herein. In this embodiment, the vehicle is a bus, so the fee may be set in advance, for example, to 2 yuan. Specifically, the collection two-dimensional code may be a collection two-dimensional code of a smartphone of a bus driver.

Further, in the present embodiment, the payment information may be directly transmitted through the UWB receiving device (for example, the UWB receiving device B shown in fig. 4) that establishes the UWB communication connection with the smartphone of the target object, thereby avoiding reestablishing the communication connection, reducing the time required for payment, and improving the convenience of payment and charging. Specifically, the UWB receiving device B sends a string corresponding to the payment two-dimensional code (the payment two-dimensional code is a string of 18 16-ary character strings), to the smart phone of the target object, and the smart phone receives the payment two-dimensional code and then automatically pays. So, at whole payment process, the user need not to draw out the smart mobile phone, also need not to remove the smart mobile phone to appointed region, can realize automatic payment, is favorable to making payment (and charge) more convenient quick.

Specifically, in this embodiment, as shown in fig. 5, after the step S200, the method further includes:

step S300, acquiring the number of target objects and the position information of the vehicle.

Step S400, sending the number of the target objects and the position information to a scheduling center.

And step S500, triggering the dispatching center to carry out vehicle dispatching control based on the number of the target objects and the position information.

Specifically, for each bus, the number of target objects on the bus and the position information of the bus may be acquired based on a preset interval (which may be a time interval or a distance interval), so as to determine the flow of people at different stations. The dispatching center is used for dispatching buses for times. During practical application, if the bus number of the bus is always sent out with the same frequency, the demand cannot be met by the bus number of times in a peak period, the phenomenon that people are crowded in limited carriages is caused, and the phenomenon that empty carriages are caused by the bus number of times in an off-peak period is caused. In the prior art, a picture of getting-on of a passenger is usually captured by a camera installed in a bus, and then the picture is sent to a bus dispatching center, and then the number of people getting-on is roughly judged by manpower, so that the frequency of getting-on is adjusted, and a dispatching mode in the prior art is not accurate and intelligent enough, so that the dispatching control of the bus cannot be performed timely, quickly and accurately.

In the embodiment, on the basis of capturing the action of getting on the bus of the passenger based on the UWB communication technology and carrying out automatic payment, the number of the target objects and the position information corresponding to the bus are obtained based on the statistics of the number of the payers, and the number of the target objects and the position information are reported to the dispatching center, and the dispatching center can analyze the information uploaded by all the buses and dynamically adjust the bus dispatching frequency of the buses. The position information is GPS position information corresponding to the vehicle. The number of the target objects can be obtained by counting payment completion information received by a smart phone of a driver. Further, the number of the target objects may be the number of passengers getting on the bus at each bus stop counted respectively. At a bus stop, the driver's smartphone can also obtain current GPS location information.

Specifically, the step S400 includes: and based on a preset sending period, sending the number of the target objects and the position information to a dispatching center through a cascaded wireless sensing network.

The preset sending period is a preset period for uploading the number and the position information of the target objects to the dispatching center. The transmission period may be determined according to time (for example, the period is determined according to a preset interval time), or may be determined according to a vehicle travel distance (for example, the period is determined according to a preset distance interval according to a vehicle travel distance), and is not particularly limited herein.

In this embodiment, the smart phone of the bus driver establishes a wireless-fidelity (Wi-Fi Aware) network, so that the number of passengers getting on the bus at each stop and the corresponding real-time GPS location information are transmitted to the bus dispatching center through the cascaded wireless Aware network.

Specifically, in this embodiment, as shown in fig. 6, the step S500 includes:

step S501, triggering the dispatching center to analyze and acquire target object dense sites and target object sparse sites based on a preset number threshold, the number of target objects sent by all vehicles, and the location information.

And step S502, improving the vehicle departure frequency corresponding to the target object dense station.

And step S503, reducing the vehicle departure frequency corresponding to the target object sparse station.

The preset number threshold is a preset threshold for judging the passenger density, and the number threshold may include a dense threshold and a sparse threshold, and the dense threshold is higher than the sparse threshold. Furthermore, different dense threshold values and sparse threshold values can be set for different bus stops respectively. When the number of target objects of a certain site is higher than the corresponding dense threshold value, the site is considered to be dense in people stream, and the site is taken as a target object dense site; and when the number of the target objects of a certain site is lower than the corresponding sparse threshold value, the people flow of the site is considered to be sparse, and the site is taken as a target object sparse site. Therefore, the number of the target objects can be counted at each bus stop, and whether the pedestrian flow of each stop is dense or sparse is judged. Further, the dispatching center can be triggered to judge the density degree of the people flow of each corresponding station by combining big data analysis based on the number of target objects and the station position information of each station, which are sent by all vehicles. For the target object dense station, the bus departure frequency of the station can be improved, and part of buses can be controlled to pass over part of target object sparse stations and directly drive to the target object dense station. For the target object sparse station, the bus departure frequency of the station can be reduced. Further, the dispatching control of the departure intervals of the vehicles can be performed based on the position information sent by each vehicle, for example, when the position intervals between the buses on the same line are too dense, the departure intervals between the buses on the line can be increased, otherwise, the departure intervals between the buses on the line are reduced, and the dispatching control method can be specifically set and adjusted according to actual requirements, and is not specifically limited herein.

In the embodiment, the description is also based on a specific application scenario, at a bus stop, a Wi-Fi Aware network is established by a smart phone of a bus driver according to smart phones in other vehicles (including buses and private cars), and the smart phone can automatically plan a shortest path (shortest path for wireless sensing network signal transmission) from the current position of the bus to a dispatching center by combining with a pre-installed map application. Fig. 7 is a schematic diagram of a wireless sensing network according to an embodiment of the present invention, where fig. 7 shows a Wi-Fi Aware network in which 4 wireless sensing groups (groups) are cascaded, that is, a Wi-Fi Aware Group 1 using a bus driver smart phone as a main device, a Wi-Fi Aware Group 2 using a private car a driver smart phone as a main device, a Wi-Fi Aware Group 3 using a private car B driver smart phone as a main device, and a Wi-Fi Aware Group 4 using a private car C driver smart phone as a main device, where a maximum communication range of each Group is 200 meters. In the Wi-Fi Aware network shown in FIG. 7, the Wi-Fi Aware group 1 is taken as an example to describe the process of building the Wi-Fi Aware group by a bus driver smart phone. According to a Wi-Fi Aware protocol, a Wi-Fi Aware group has 3 roles, namely a main device, a non-main synchronous device and a non-main asynchronous device, and the building process of the Wi-Fi Aware group can be divided into the following 3 steps: the method comprises the following steps that firstly, a bus driver smart phone is used as a main device and sends a discovery beacon frame to discover surrounding private car smart phones to form a Wi-Fi Aware group, and a plurality of private car smart phones randomly become non-master synchronous devices or non-master asynchronous devices; secondly, the master device and the non-master synchronization device of the group send synchronization beacon frames to synchronize the clock of the whole network, so as to reduce the power consumption of the group; and thirdly, in the group, the main device, the non-main synchronous device or the non-main asynchronous device can receive and transmit the service discovery frame to acquire the specific information. After the Wi-Fi Aware group is successfully established, one device in the group may send a message to another device in the same group, may send a message to multiple devices in the same group, or may broadcast a message to all devices in the same group, where the message is carried on a service discovery frame. The specific message is delivered through the service discovery frame in the embodiment on the premise of conforming to the Wi-Fi Aware protocol. Fig. 8 is a schematic diagram of a format of a service discovery Frame according to an embodiment of the present invention, where Category means that the type of the Frame is a Public Action Frame (Public Action Frame); action Field refers to the frame of public Action associated with a given manufacturer; OUI refers to organization Unique number (organization Unique Identifier); OUI Type refers to the Type of OUI; attributes refers to Attributes, including service description Attributes and manufacturer specific Attributes. In the manufacturer-specific Attribute, Attribute ID refers to the number of the manufacturer-specific Attribute; length refers to the sum of the byte lengths of OUI and Body; OUI refers to the manufacturer's number; body refers to manufacturer specific information. Fig. 9 is a schematic diagram of a simplified format of a service discovery frame according to an embodiment of the present invention, where a Body field in fig. 9 is the Body field in fig. 8, and fig. 10 is a schematic diagram illustrating a definition of a message ID in fig. 9 according to an embodiment of the present invention. In fig. 9, the message ID field has different values and corresponding meanings, and reference is specifically made to fig. 10. After the Wi-Fi Aware group 1 is successfully established, a circular area with a bus driver smart phone as a center and a radius of 200 meters is formed, and a network with a plurality of private cars is arranged in the circular area. Fig. 11 is a schematic diagram of a format of a message for screening private cars by a bus driver smart phone according to an embodiment of the present invention, where the bus driver smart phone knows a shortest path from a bus to a dispatching center, and therefore, the bus driver smart phone broadcasts information for screening private cars in group 1, and requests that a private car driver smart phone within a preset range threshold (e.g., a range of plus or minus 10 meters in an arrow direction) responds from a current position of the bus shown in fig. 7, and a corresponding message format is shown in fig. 11. Fig. 12 is a schematic diagram showing a format of a message that a private car driver smart phone responses to can transmit bus-carried passenger information according to an embodiment of the present invention, where after receiving the message, the private car driver smart phone of group 1 indicates that bus-carried passenger information can be transmitted if the private car driver smart phone is within a range threshold, and a corresponding message format is shown in fig. 12. Generally speaking, in daytime, there are more private cars in a city, the bus driver smart phone receives response messages of a plurality of private car driver smart phones, and the current position of the private car is attached to the messages, so that the bus driver smart phone calculates the current distance between the bus and the private car, and randomly selects one private car driver smart phone as a relay (the distance between the private car and the bus is between 100m and 200 m). Then, the smart phone of the bus driver sends the information of the current position of the bus, the number of people getting on the bus stop and the like to the selected private car, and the message format of the corresponding smart phone for transmitting the passenger carrying information of the bus is shown in fig. 13. After the bus driver smart phone sends the bus passenger information, the message for dissembling the group is broadcasted, and the message format for dissembling the Wi-Fi Aware group by the corresponding smart phone is shown in fig. 14. Similarly, the smart phone of the driver A of the private car also sends the corresponding information of the current position of the bus, the number of passengers getting on the bus at the bus stop and the like according to the process, and finally the information is transmitted to the dispatching center, and the detailed process is not repeated. The bus dispatching center is fixed in position and known, the bus dispatching center is provided with Wi-Fi hardware equipment and supports a Wi-Fi Aware protocol, after receiving bus passenger information, the private car C calculates the distance between the current position of the private car C and the bus dispatching center, and if the distance is less than 200m, a smart phone of a driver of the bus C and the bus dispatching center establish a Wi-Fi Aware group and send the bus passenger information to the bus dispatching center; and if the distance is greater than 200m, the smart phone of the private car C driver transmits the bus passenger information by taking other private cars as relays until the distance between the last private car and the bus dispatching center is less than 200m, and the last private car and the bus dispatching center construct a Wi-Fi Aware group and send the bus passenger information to the bus dispatching center. Further, in order to encourage private cars to participate in the motivation for delivering information, a corresponding reward mechanism may be provided. In the practical application process, the bus passenger carrying information (including the number of the target objects at the stop and the corresponding stop position information) is sent out from the bus, and the bus passenger carrying information is received by the dispatching center, so that the time consumption is very short (within 1 second). All running buses in a city can send corresponding real-time passenger carrying information to a bus dispatching center in real time, and the bus dispatching center can judge stations with dense pedestrian flow (stations with dense target objects) and stations with sparse pedestrian flow (stations with sparse target objects) by combining big data analysis and dynamically adjust the stations. Specifically, for stations with large pedestrian volume, the departure frequency of the buses can be increased, and partial buses can directly drive to the stations with large pedestrian volume when passing the stations; if the passenger flow of all stops of a certain bus line in a certain time period is less, the departure frequency of the buses of the line can be reduced; if the bus breaks down and is anchored, the bus departure frequency can be increased; if the intervals between the buses on the same line are too dense or too sparse, the departure interval time of the buses on the line can be properly adjusted. Therefore, the phenomenon that the bus is full of people or empty can be greatly reduced. The format schematic diagram (for example, fig. 8) provided in this embodiment only illustrates the format of the corresponding message, and some specific values are not filled, and the specific values may be determined and filled according to actual requirements in the actual use process, which is not specifically limited herein.
