Description
Technical Field
The invention relates to the field of network taxi taking, in particular to a network taxi appointment rapid identification method.
Background
In the process of using the network car reservation by passengers, the problem that the reserved car is inconsistent with the actual riding car sometimes occurs. In order to avoid such operation risks, the current method of the network platform is to issue the information of the model, color, license plate and the like of the operated vehicle to the mobile phone of the passenger, so that the passenger can observe and verify the information by himself. However, in some cases, the license plate of the reserved vehicle (i.e. the fake-licensed vehicle) is applied by the illegal vehicle, and even the external features of the appearance, the vehicle type and the like of the vehicle are basically consistent, which increases great difficulty for the identification of the passenger, thereby causing great threats to the safe passenger departure and the orderly operation of the network car reservation market.
In 2016, the temporary method for managing the service of taxi appointed by network is released and implemented. The method makes clear requirements on the normative operation of the network appointment car, wherein the following requirements are stipulated: the network appointment vehicle should be equipped with a vehicle satellite positioning device and an emergency alarm device (hereinafter, the device is simply referred to as a vehicle-mounted terminal) having a driving recording function. It should be noted here that the vehicle location information viewed by the passenger on the mobile phone application is not generally obtained from the vehicle-mounted terminal, but is still obtained from the mobile phone application of the driver, that is, there is a possibility that the location of the vehicle to be called up displayed on the mobile phone application of the passenger is not consistent with the actual location of the vehicle, which becomes a loophole available to the illegal driver.
Disclosure of Invention
In order to solve the problems, the invention aims to provide a method for quickly identifying network appointment, which carries out Bluetooth communication by using a Bluetooth device address of a vehicle-mounted terminal of the network appointment so as to achieve the purpose of identifying legal network appointment.
The specific scheme is as follows:
a network taxi appointment quick identification method comprises the following steps:
s1: a passenger issues a car calling request to a service platform through a mobile terminal, and the service platform issues a car calling task to a vehicle-mounted terminal according to the car calling request;
s2: after the driver responds to the car calling task, the Bluetooth equipment address of the vehicle-mounted terminal configured on the car to be called is sent to the service platform;
s3: the service platform sends the received Bluetooth equipment address to the passenger mobile terminal;
s4: after the vehicle to be called arrives at the passenger boarding place, the Bluetooth device of the vehicle-mounted terminal is started and set to be in a paging scanning state; the passenger opens the Bluetooth function of the mobile terminal, generates a frequency hopping sequence and a device access code required by paging by using the received Bluetooth device address, and performs Bluetooth paging on the vehicle-mounted terminal;
s5: and judging whether the mobile terminal receives a paging response of the Bluetooth of the vehicle-mounted terminal within a limited time, if so, judging that the vehicle is a legal vehicle registered after approval and verification by the network car booking service platform, and if not, judging that the vehicle is an illegal vehicle.
Furthermore, the vehicle-mounted terminal is fixedly arranged on the vehicle by using an anti-dismounting technology, when the vehicle-mounted terminal is illegally dismounted, the service platform receives an illegal dismounting alarm, and the service platform forbids the order-taking function of the vehicle-mounted terminal.
Further, the method for generating the frequency hopping sequence and the device access code required for paging in step S4 is generated by using a 79-hop system specified in the bluetooth specification.
The invention adopts the technical scheme and utilizes the characteristics of Bluetooth frequency hopping communication to disclose a Bluetooth interactive communication mode different from the traditional processing mode, which is used for identifying and verifying the truth of the network appointment. The method removes the pairing and authentication of the link manager communication and the inquiry process of the Bluetooth baseband communication in the Bluetooth application, simplifies the paging process of the Bluetooth baseband communication and the like, only partially utilizes the paging process of the Bluetooth baseband communication, and only needs to receive the paging response of the equipment, namely only needs the first 2 steps of the paging process, thereby generating unexpected technical effects.
The bluetooth frequency hopping sequence is random, at least pseudo-random, does not know the address of the bluetooth device, and is difficult to generate a corresponding frequency hopping sequence, so the possibility of cracking the method is very small. In addition, most of mobile phones used by the passengers in a call have the Bluetooth function, the identification process is very quick and efficient, and the method has good popularization.
In the whole interaction process, the passenger mobile phone does not record information such as the address of the vehicle-mounted terminal Bluetooth device and the like because the pairing and authentication process is not carried out. Therefore, the method can not reveal the address information of the Bluetooth equipment of the vehicle-mounted terminal and can be used repeatedly.

Detailed Description
To further illustrate the various embodiments, the invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. Those skilled in the art will appreciate still other possible embodiments and advantages of the present invention with reference to these figures. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.
The invention will now be further described with reference to the accompanying drawings and detailed description.
The first embodiment is as follows:
an embodiment of the present invention provides a method for quickly identifying a network appointment, as shown in fig. 1, which is a schematic flow chart of the method for quickly identifying a network appointment according to the embodiment of the present invention, and the method may include the following steps:
s1: the passenger issues a car calling request to the service platform through the mobile terminal, and the service platform issues a car calling task to the vehicle-mounted terminal according to the car calling request.
The mobile terminal is a mobile terminal with a Bluetooth function.
The issuing of the car calling request is that the car calling request is issued by using an application corresponding to a service platform installed on the mobile terminal.
The vehicle-mounted terminal is fixedly arranged on a vehicle by using an anti-dismounting technology, when the vehicle-mounted terminal is illegally dismounted, the service platform can receive an illegal dismounting alarm, and the service platform can forbid the order receiving function of the vehicle-mounted terminal.
S2: and after the driver responds to the car-calling task, the Bluetooth equipment address of the vehicle-mounted terminal configured on the car to be called is sent to the service platform.
S3: and the service platform sends the received Bluetooth equipment address to the mobile terminal of the passenger.
S4: after the vehicle to be called arrives at the passenger boarding place, the Bluetooth device of the vehicle-mounted terminal is started and set to be in a paging scanning state. The passenger opens the Bluetooth function of the mobile terminal, generates a frequency hopping sequence and a device access code required by paging by using the received Bluetooth device address, and performs Bluetooth paging on the vehicle-mounted terminal.
Bluetooth communication is a frequency hopping communication technology, and a certain number of frequencies (for example, 16 channel frequencies) are randomly arranged and selected on 23 or 79 channels (for short, 23 or 79 hops) of a 2.4G frequency band to perform fast frequency hopping. The hopping sequences of both communication parties do not coincide with each other, and communication cannot be performed. The common bluetooth usage mode is that the master device searches for the slave device, and then switches to a paging process after obtaining the bluetooth address information of the slave device, and then switches to a piconet for communication after paging is completed, and then various application communications can be performed after the processes of pairing and authentication (the paired devices can skip pairing and direct authentication).
In the paging process, the frequency hopping sequence used by the paging party and the paged party is generated by the address of the Bluetooth device of the paged device through a certain algorithm. The baseband communication during paging also takes the access code generated by the address of the bluetooth equipment of the paged equipment through a certain algorithm as the identification mark, the access code is incorrect, and the receiver discards the received data. The normal paging process comprises three steps: 1. paging by the master control equipment, and scanning and paging by the slave equipment; 2. the slave device scans the page to the master device and responds to the page; 3. and the master device receives the response of the slave device, sends the basic parameters of the piconet communication to the slave device and then enters the piconet communication process.
When the condition that 23 hops or 79 hops are already specified, the paging frequency hopping sequence and the access code generated by the Bluetooth device address have uniqueness.
When the Bluetooth equipment address of the vehicle-mounted terminal is known, the Bluetooth inquiry process can be skipped, and the Bluetooth equipment address is directly utilized to carry out Bluetooth paging on the vehicle-mounted terminal. The frequency hopping sequence and the device access code required by the paging operation are generated by the bluetooth device address of the paged vehicle-mounted terminal according to a bluetooth specification algorithm, and the 79-hop system specified in the bluetooth specification is adopted in the embodiment.
S5: and judging whether the mobile terminal receives a paging response of the Bluetooth of the vehicle-mounted terminal within a limited time, if so, judging that the vehicle is a legal vehicle registered after approval and verification by the network car booking service platform, and if not, judging that the vehicle is an illegal vehicle.
The passenger mobile terminal only needs to page the Bluetooth device of the vehicle-mounted terminal, does not need to enter a piconet for communication and establishing connection, and does not need to perform subsequent operations such as Bluetooth pairing, authentication and the like with the vehicle-mounted terminal Bluetooth according to the traditional Bluetooth communication processing. The vehicle-mounted terminal Bluetooth does not enter an inquired state, namely the vehicle-mounted terminal Bluetooth is invisible to other Bluetooth devices which do not know the vehicle-mounted terminal Bluetooth address, so that only the mobile terminal of a passenger can successfully perform Bluetooth paging on the vehicle-mounted terminal corresponding to a summons vehicle, and other Bluetooth devices cannot page the vehicle-mounted terminal because the other Bluetooth devices do not know the vehicle-mounted terminal Bluetooth address.
The embodiment of the invention utilizes the characteristic of Bluetooth frequency hopping communication, discloses a Bluetooth interactive communication mode different from the traditional processing mode, and is used for identifying and verifying the truth of a network appointment. The method removes the pairing and authentication of the link manager communication and the inquiry process of the Bluetooth baseband communication in the Bluetooth application, simplifies the paging process of the Bluetooth baseband communication and the like, only partially utilizes the paging process of the Bluetooth baseband communication, and only needs to receive the paging response of the equipment, namely only needs the first 2 steps of the paging process, thereby generating unexpected technical effects.
The bluetooth frequency hopping sequence is random, at least pseudo-random, does not know the address of the bluetooth device, and is difficult to generate a corresponding frequency hopping sequence, so the possibility of cracking the method is very small. In addition, most of mobile phones used by the passengers in a call have the Bluetooth function, the identification process is very quick and efficient, and the method has good popularization.
In the whole interaction process, the passenger mobile phone does not record information such as the address of the vehicle-mounted terminal Bluetooth device and the like because the pairing and authentication process is not carried out. Therefore, the method can not reveal the address information of the Bluetooth equipment of the vehicle-mounted terminal and can be used repeatedly.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
