Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, although the description uses the charging of an electric vehicle as an example to describe the automatic authentication method of the present invention, it is obvious that the method of the present invention is also applicable to other authentication occasions, and those skilled in the art can make adjustments to the application occasions as needed without departing from the basic principle of the present invention, and therefore, the present invention will also fall into the protection scope of the present invention.
The automatic authentication system based on distance activation comprises a positioning module, an authentication module and a control module. The positioning module is used for acquiring the positions of the first target and the second target, and further determining the distance between the first target and the second target according to the positions of the first target and the second target. In a preferred embodiment, the first object is a mobile terminal, such as an electric car, whose real-time position can be obtained by means of a positioning module. However, the second objective is a fixed terminal, such as a charging pile, whose position can be obtained in real time by the positioning module, or can be pre-stored and called directly by the positioning module. Therefore, the term "acquiring" in the present application should be understood in a broad sense, and may be either acquiring the real-time position of the moving object or directly or indirectly calling the pre-stored position of the fixed object. Furthermore, the positioning module may be a part of an existing system, such as a positioning module of an existing car navigation system, or may be a separate device independent of an existing system, without departing from the basic principle of the present invention, and therefore, will fall within the scope of the present invention.
The control module can be respectively communicated with the positioning module and the authentication module, and is used for comparing the distance between the first target and the second target with a set threshold value and activating the authentication module when the distance is less than or equal to the set threshold value. Similarly, the control module may be physically part of an existing system, such as the vehicle VCU itself or a sub-module thereof, or may be a dedicated device separate from the existing system.
The authentication module is used for authenticating the first target. When the authentication module is activated, the second target authenticates the first target through the authentication module. Further, when the authentication request information of the first target collected by the authentication module is matched with the pre-stored legal authentication information, the second target provides authorization for the first target.
Further, the authentication module preferably comprises a first authentication module and a second authentication module. The first authentication module is arranged on the first target, and the second authentication module is arranged on the second target. When the distance between the first target and the second target is smaller than or equal to the set threshold value, the first authentication module and the second authentication module are activated simultaneously (or the control module activates one authentication module first and then activates the other authentication module by the activated authentication module first), the first authentication module sends authentication request information outwards, the second authentication device matches the authentication request information with the pre-stored legal authentication information after receiving the authentication request information, and then whether the second target should pass the authentication request of the first target is judged according to the matching result. Like the positioning module and the control module, the first authentication module and the second authentication module can be implemented in combination with the existing system or can be configured as dedicated modules.
Alternatively, the person skilled in the art may also set an authentication module (such as the second authentication module described above) only on the second object, if necessary. And when the distance between the first target and the second target is less than or equal to the set threshold value, the second authentication module is activated and sends authentication invitation information to the outside. The first target sends authentication request information to the second authentication module when receiving the authentication invitation information; the second authentication module matches the authentication request information with the pre-stored legal authentication information and judges whether the authentication request of the first target should be passed or not according to the matching result.
Furthermore, the person skilled in the art can also set an authentication module (such as the first authentication module mentioned above) only on the first object, if necessary. When the first authentication module is activated, the first authentication module directly sends authentication request information outwards. And after receiving the authentication request information, the second target matches the pre-stored legal authentication information, and then judges whether the second target passes the authentication request of the first target or not according to the matching result.
In a preferred embodiment of the present invention, the first object is an object to be charged and replaced, and specifically, the object to be charged and replaced may be an electric automobile, an electric bicycle, or the like. The second object is a charging and replacing facility, which may be, in particular, a dc charging pile, an ac charging pile, a dc charger, an ac charger, a mobile charging vehicle, or the like. Therefore, the authorization of the second target to the first target is to charge or replace the battery object to be charged or replaced by the charging and replacing facility, for example, the charging pile authorizes charging of the electric vehicle, or the mobile charging vehicle authorizes charging of the electric vehicle.
The automatic authentication method based on distance activation according to the present invention will be described in detail with reference to the accompanying drawings in conjunction with a charging pile and an electric vehicle.
As shown in fig. 1, the automatic authentication method based on distance activation of the present invention mainly includes: step S110, acquiring the positions of a charging pile and an electric automobile; step S120, determining the distance between the charging pile and the electric automobile according to the positions of the charging pile and the electric automobile; step S130, comparing the distance with a set threshold value; step S140, when the distance is less than or equal to the set threshold value, activating the authentication module; and S150, authenticating the electric automobile through the authentication module.
Specifically, in step S110, the positions of the charging pile and the electric vehicle are obtained through the positioning module. As mentioned above, the "acquisition" can be either a real-time location, for example for an electric vehicle, or a call to a pre-stored location, for example for a charging post.
Specifically, in step S120, the positioning module determines the distance between the charging pile and the electric vehicle according to the position obtained in step S110. Or a person skilled in the art can calculate the real-time distance between the charging pile and the electric vehicle according to the positions of the charging pile and the electric vehicle through other functional modules or functional units, such as a control module.
Specifically, in step S130, the real-time distance obtained in step S120 is compared with a set threshold. The threshold value may be set by a person skilled in the art according to actual conditions or safety requirements, and may be, for example, 5m, 10m, 20m, or the like. It should be further noted that the value of the threshold is not too large, so that the charging pile is prevented from frequently authenticating a passing legal electric vehicle; the value of this threshold value should not the undersize yet, when avoiding electric automobile to close on filling electric pile, fills electric pile and has not yet authorized electric automobile, influences user's the experience of charging.
Specifically, in step S140, when the real-time distance is less than or equal to the set threshold, the control module activates the authentication module; when the real-time distance is larger than the set distance, the control module enables the authentication module to keep a standby state or a closed state. The technical effect of the setting is that even if other people illegally steal the authentication key and send an authentication request to the authentication module on the charging pile, if the electric automobile which is legally registered is not near the charging pile, the authentication module can keep a non-working state, so that the illegal electric automobile cannot pass authentication and cannot be charged.
Furthermore, the mode of determining that the real-time distance between the charging pile and the electric automobile is smaller than or equal to the set threshold value can be judged by an infrared judgment module, an ultrasonic judgment module, a laser judgment module, a double-shooting judgment module and the like besides the positioning module. Those skilled in the art can understand that the control module, the positioning module and other forms of distance determination modules may be disposed on the electric vehicle, the charging pile, or a remote location, such as a background server or a cloud server.
Specifically, in step S150, the charging pile authenticates the electric vehicle through the authentication module. Preferably, the authentication module comprises a first authentication module and a second authentication module. The first authentication module is arranged on the electric automobile, and the second authentication module is arranged on the charging pile. When the distance between the charging pile and the electric automobile is smaller than or equal to a set threshold value, the first authentication module and the second authentication module are activated simultaneously (or one authentication module is activated firstly, and then the other authentication module is activated by the authentication module which is activated firstly), the first authentication module sends authentication request information outwards, the second authentication device matches the authentication request information with pre-stored legal authentication information after receiving the authentication request information, and then whether the charging pile passes the authentication request of the electric automobile is judged according to the matching result.
Those skilled in the art can also set an authentication module (such as the second authentication module described above) only on the charging pile according to needs. And when the distance between the charging pile and the electric automobile is smaller than or equal to a set threshold value, the second authentication module is activated and sends authentication invitation information to the outside. The electric automobile sends authentication request information to the second authentication module when receiving the authentication invitation information; the second authentication module matches the authentication request information with the pre-stored legal authentication information and judges whether the authentication request of the electric automobile should be passed according to the matching result.
The person skilled in the art can also set an authentication module (such as the first authentication module described above) only on the electric vehicle as required. When the first authentication module is activated, the first authentication module directly sends authentication request information outwards. And after receiving the authentication request information, the charging pile matches the authentication request information with prestored legal authentication information, and then judges whether the charging pile should pass the authentication request of the electric automobile or not according to the matching result.
In a preferred embodiment, the sending and receiving of the authentication invitation information and/or the authentication request information may be performed by a wireless communication method or a wired communication method. The wireless communication method may be, for example, WIFI, bluetooth, ZIGBEE, or the like, and the wired communication method may be, for example, power line carrier communication (PLC), or the like. In addition, the contents of the authentication invitation information and the authentication request information can be flexibly set according to the requirements. As an example, the authentication invitation information may include parameters related to the charging post and charging inquiry information for confirming the electric vehicle, and the authentication request information may include, but is not limited to, a frame number (VIN code) of the electric vehicle, an engine number (motor number), a battery number, a specific identification code preset and stored in the electric vehicle, or other numbers capable of identifying the identity of the electric vehicle. Changes and modifications in the information content do not depart from the basic concept of the present invention and thus fall within the scope of the present invention.
Further, in order to execute the method of the present invention, a legal electric vehicle needs to be registered and authenticated in the charging pile in advance, or in a background database or a cloud database that can communicate with the charging pile, which is a default premise of the technical scheme of the present invention. In other words, the technical scheme of the invention only judges the distance between the legally registered electric automobile and the charging pile, and because other electric automobiles are not in communication with the system of the invention, the system of the invention does not need to judge the distance between the legally registered electric automobile and the charging pile, and cannot judge the distance between the legally registered electric automobile and the charging pile. In addition, the operation of receiving the authentication request can be performed at the charging pile or at a remote end depending on the setting position of the authentication device. Moreover, the matching and judging operation can be performed by the second authentication module at the charging pile, or by a background server at a remote end.
Furthermore, in a preferred embodiment of the present invention, an authentication device capable of performing authentication information interaction with an authentication module on the charging pile is disposed on the electric vehicle, and specifically, the authentication device may be a smart car key, a vehicle-mounted smart terminal disposed on the vehicle, a mobile phone, or the like. Or other devices which are not easy to lose and are not easy to be falsely used by other people can be used as the authentication device by the technical personnel according to the needs.
It should be noted that, when the specific electric vehicle is the subject of legal registration and authentication in advance, in step S140, when the real-time distance between the electric vehicle and the charging pile is smaller than the set distance threshold, the charging pile directly provides authorization for the electric vehicle, so as to simplify the authentication process.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
