Description
Technical Field
The invention relates to the technical field of charging piles, in particular to a charging method and system based on a radio frequency identification technology.
Background
Along with the development of new energy, the electric automobile serving as a future traffic tool is rapidly developed, a large number of electric automobile types are promoted by traditional automobile manufacturing enterprises and new automobile manufacturing forces on the market, and meanwhile, the charging pile matched with the electric automobile types is formed. Because of numerous vehicle types, the types of the charging piles are various, and the surrounding ecology of the electric vehicle is still required to be improved continuously although related standards are used for constraint and standardization. Taking the electric automobile charging process as an example, identity confirmation of the vehicle (user) is needed before charging, the charging can be approved only after the right confirmation is successful, and charging after the charging is finished can not be realized, so that plug-and-play charging can be realized, namely after the charging gun is connected with the electric automobile, the identity of the vehicle (user) can be automatically identified and confirmed, and the charging can be checked without errors. At present, some plug-and-play schemes exist in the industry, but as unified standards are not available, and differences exist among different manufacturers, different piles and different vehicle types, compatibility cannot be achieved.
In the traditional technology, the scheme of non-plug-and-play basically comprises two types, namely, the scheme is that the user identity information is confirmed through the card swiping identity, the scheme needs the card swiping operation of a charging pile when a user charges, the plug-and-play charging cannot be realized, the user experience is poor, the user identity card is easy to lose and crack, and the management and control risk exists. Under the application scene of the charging pile operation station, the station faces a large number of clients, if each client is enabled to transact cards, the management is not very realistic and difficult, and the clients without cards are lost; under the scene of sharing the private pile, the private pile cannot share the card-free user. The other is to identify identity information by means of scanning two-dimension codes by a mobile phone, wherein the two-dimension codes with unique corresponding identification are adhered to the pile body of the charging pile, and the user needs to scan codes by using an APP (Application) supported by the charging pile during charging, and identity confirmation is carried out through the charging pile and a mobile phone cloud platform. The identity confirmation requires that the user can not realize plug and play by scanning codes, and APP supported by a charging pile is required in the mobile phone, so that the universal compatibility is poor.
In the conventional technology, the plug-and-play scheme generally includes the following steps, firstly, the mobile phone charging pile Bluetooth (BT) communication plug-and-play: when a user carries a mobile phone to enter a Bluetooth communication range of a charging pile, the mobile phone and the charging pile establish Bluetooth communication, data interaction confirms identity, and the universal compatibility is poor even if plug-and-play is realized, and the universal compatibility is not unified, so that the universal compatibility is difficult to realize due to the fact that differences exist between different brands and different models. And the mobile phone and the charging pile Bluetooth communication can not determine which parking space is communicated with the mobile phone, and only the electric vehicle in the parking lot can be confirmed to be communicated with the mobile phone, and a user is required to make a selection on the APP. Second, the bluetooth communication of the vehicle stake (BT) plug and play: at present, the vehicle stake communication mainly is through bluetooth, when the electric vehicle enters into the bluetooth identification range of the charging stake, the vehicle stake carries out bluetooth communication to establish connection, and identity confirmation is carried out after data interaction, so that plug and play is realized, but the scheme needs to support bluetooth communication on hardware and software communication protocols between the vehicle stake, and the general compatibility is poor because of differences among different manufacturers, different models and different vehicle types. Thirdly, plug-and-play of car stake accuse wired communication (CAN, PLC, CP mode): the current technical scheme of vehicle pile wired communication mainly comprises an alternating current charging pile and a direct current charging pile, wherein the alternating current pile is communicated through a CP signal, the direct current pile is communicated by adopting CAN (controller area network) in national standard and the direct current pile is communicated by adopting PLC (programmable logic controller) in European standard. The vehicle pile wired communication is feasible in theory, can realize plug and play, but has no unified standard and poor universal compatibility, and is difficult to realize due to the differences among different manufacturers, different models and different vehicle types. Fourth, visual recognition (VI) plug-and-play: the electric vehicle enters the identification range of the charging pile camera, the identity is confirmed by identifying the license plate of the vehicle type, and the plug-and-play charging is realized, but the technical scheme has high cost and has the influence of camera blind areas and environmental brightness. Fifth, plug-and-play without identity confirmation: the charging pile defaults to be connected with the charging gun and the vehicle, and can be directly charged, so that the scheme is easy to have the risk of stolen charging.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a flowchart of a charging method based on a radio frequency identification technology according to an embodiment of the present invention.
As shown in fig. 1, the charging method based on the radio frequency identification technology according to the embodiment of the invention may include the following steps:
s1, when a vehicle enters a preset range of radio frequency identification, acquiring vehicle information, and acquiring identity information of a user according to the vehicle information.
According to one embodiment of the present invention, acquiring vehicle information includes: vehicle information is obtained by identifying an on-board unit and/or an electronic license plate of the vehicle.
Specifically, as shown in fig. 2, a radio frequency identification device is installed above each charging pile, each charging pile corresponds to one parking space, and when a vehicle arrives at the front end of the parking space, the radio frequency identification device identifies a vehicle-mounted unit and/or an electronic license plate of the vehicle to acquire vehicle information, and acquires identity information of a user corresponding to the vehicle according to the vehicle information.
It should be noted that, the position, the transmitting power and the angle of the radio frequency identification device on the parking space are set to limit the range of the antenna radiation and the receiving area of the radio frequency identification system; in order to reduce the interference of adjacent parking spaces, different channels are adopted for different parking spaces, the frequency of each channel is slightly different in the allowable range, the difference of the parking spaces is reflected through the difference of the frequencies, and the adjacent interference is avoided by distinguishing the parking spaces by matching with a narrow-band receiving technology. Taking fig. 2 as an example, the radio frequency identification device 1 in the parking space 1 adopts the frequency of the channel 1 to identify the vehicle on the parking space, and when the vehicle 1 receives the information, the frequency of the channel 1 is adopted to reply; the radio frequency identification device 2 in the parking space 2 adopts the frequency of the channel 2 to identify the vehicle on the parking space, and the frequency of the channel 2 is adopted to reply after the vehicle 2 receives the information. Therefore, each parking space has different channel frequencies, and the OBU or the electronic license plate on the vehicle can correspondingly send out different channel frequencies, so that parking space distinction and interference prevention are realized. And, the radio frequency identification device supports the main stream working frequency (for example, the main stream working wave band mainly comprises 900MlHz, 2.45GHz and 5.8GHz frequency bands), and the transmission power can be adjusted within the allowable range to ensure the identification distance. Therefore, different channels are adopted in different parking spaces, the frequencies of the channels are slightly different in the allowable range, the difference of the parking spaces is reflected through the difference of the frequencies, and then the parking spaces are distinguished by matching with a narrow-band receiving technology to avoid adjacent interference.
S2, judging whether the identity information of the user meets the preset charging condition.
According to one embodiment of the present invention, the preset charging conditions may include: one or more of completing identity registration, completing payment setup, and reserving a user.
That is, the user needs to register and bind the fund account in the cloud server on the premise of realizing plug-and-play and non-inductive payment by using the charging system, and the registered information needs to be consistent with the OBU or electronic license plate information, so that the cloud server has authentication basis for the received vehicle identity information. Whether the vehicle meets the condition of plug and play or not is judged according to the identity information of the user, for example, whether the user completes registration of the identity information on the APP or whether payment setting is completed or not is judged, for example, charging fee deduction can be directly carried out from a bank card and a rechargeable card bound on the OBU after charging is finished, or fee deduction is carried out through a fund account bound with the OBU or an electronic license plate, and whether the vehicle is a reservation user or not is judged. The reservation user means that the user reserves the charging time in the APP in advance.
According to one embodiment of the present invention, determining whether the identity information of the user satisfies a preset charging condition includes: the identity information of the user is sent to a cloud server; judging whether a user meets preset charging conditions or not through a cloud server; when the identity information of the user meets the preset charging condition, a charging instruction is sent to the charging pile through the cloud server, so that the charging pile charges the vehicle.
That is, whether the user meets the preset charging condition is judged through the cloud server, and when the user inserts the charging gun into the vehicle, the vehicle can be charged through the charging pile. When the parking space is provided with the barrier gate or the ground lock, the barrier gate or the ground lock on the parking space is controlled to be opened when the identity information of the user meets the preset condition, so that the vehicle can conveniently enter the parking space, and when the user inserts the charging gun into the vehicle, the vehicle is charged through the charging pile.
According to another embodiment of the present invention, determining whether the identity information of the user satisfies a preset charging condition includes: the identity information of the user is sent to the charging pile; judging whether a user meets preset charging conditions or not through the charging pile, and charging the vehicle when the identity information of the user meets the preset charging conditions; or the identity information of the user is sent to the cloud server through the charging pile, and when the cloud server judges that the identity information of the user meets the preset charging condition, a charging instruction is sent to the charging pile so that the charging pile charges the vehicle.
In other words, authentication can be performed through the cloud server (whether the identity information of the user meets the preset charging condition or not) and authentication can also be performed through the charging pile.
And S3, charging the vehicle when the identity information of the user meets the preset charging condition.
Specifically, when the identity information of the user satisfies a preset charging condition, the charging stake begins to charge the vehicle when the user inserts the charging gun into the vehicle. After the charging is finished, the charging pile informs the cloud server to carry out electric charge settlement, and a settlement account can be a bound fund account or a bank card and a rechargeable card in the OBU. In addition, the radio frequency identification device is also used for identifying whether the vehicle leaves the parking space, and when the vehicle leaves the parking space, the cloud server is informed to settle parking fee. After the vehicle leaves the parking space, the control barrier or ground lock is closed.
According to an embodiment of the present invention, the above charging method based on the radio frequency identification technology further includes: receiving a reservation charging instruction of a user through a cloud server, wherein the reservation charging instruction comprises: reserving charging time and reserving a charging parking space; the cloud server distributes the charging piles according to the reserved charging instruction and feeds back the position information of the reserved charging piles to the user; the reserved charging pile is locked before the reserved user arrives at the reserved charging pile or the reserved charging time. It should be noted that, the reservation charging instruction may further include a charging pile for reservation charging, when two charging guns are arranged on the charging pile, two parking spaces are generally corresponding, at this time, the reservation of the parking spaces is needed, and when only one charging gun is arranged on the charging pile, both the reservation of the parking spaces and the charging pile can be achieved.
Further, according to an embodiment of the present invention, before the subscriber arrives at the reserved charging pile or reaches the reserved charging time, locking the reserved charging pile includes: when the reserved user arrives at the reserved charging pile and the reserved charging time is not reached, controlling the charging pile to charge the vehicle; and when the reserved user does not reach the reserved charging pile and the reserved charging time is not reached, delaying the first preset time, and unlocking the reserved charging pile if the reserved user does not reach the reserved charging pile yet. The first preset time can be calibrated according to actual conditions.
Specifically, the user can reserve and charge through the mobile phone APP, when the user clicks the reservation function, the cloud server receives a reservation and charge instruction, distributes proper charging piles according to the reserved time place of the user, informs the user and the charging piles, and the charging piles are in a locking state before the vehicle of the user reaches. That is, the reserved parking space charged by the mobile phone has exclusivity in unit time, and the vehicle can be allowed to enter only if the reserved vehicle reaches the parking space and is identified as the reserved parking space by the radio frequency identification, and the road gate or the ground lock on the parking space can be used for allowing the vehicle to enter.
In addition, when the identity information of the user is identified as the reserved user, the vehicle is charged when the plug-and-play condition is met, otherwise, the vehicle is not allowed to enter the reserved parking space. When the reserved time is reached, if the reserved vehicle information is not recognized, delaying the first preset time, and if the reserved vehicle information is not recognized yet, unlocking the charging pile to prevent the charging pile from being occupied. The parking space and the charging condition of the destination charging station are obtained remotely through the reservation function of the mobile phone, the parking space and the charging service are reserved in advance, and the shortage of the parking space and the charging in the peak period is avoided.
In one embodiment of the invention, for a private pile user, as long as the OBU or the electronic license plate at the vehicle end of the private pile user is in the radio frequency identification range of the charging pile, the identity can be confirmed to be plugged and charged, and the risk of theft and brushing is avoided. Under the private pile sharing scene, the vehicle can be plugged and charged immediately after registering or reserving, and identity confirmation is carried out through an OBU or an electronic license plate of the radio frequency identification vehicle end after the vehicle arrives at the site, so that the problem that the private pile sharing is not supported under the existing plug and play scheme is solved.
As a specific example of the present invention, as shown in fig. 3, the above-described charging method may include: and the user uploads vehicle information and binds the fund account through the mobile phone APP, and the information is registered in the cloud server. The mobile phone APP reserves to charge, the purpose of the step is to reserve to charge as an optional step, and the mobile phone APP is used for checking the parking space and the charging pile condition of the destination charging station to reserve the parking space and the charging pile. The vehicle enters a radio frequency identification range, the radio frequency identifies OBU or electronic license plate identity information, and the identified vehicle information is transmitted to a cloud server. The cloud server performs identity authentication on the received vehicle information, and the authentication is performed mainly according to the information which is registered and bound by the user and comprises reservation information. The cloud server judges whether the identity information accords with the plug-and-play condition according to the authentication, if so, the cloud server informs that the parking space guiding control opens a barrier gate or a ground lock and performs acousto-optic reminding, and informs that the charging pile is ready for plug-and-play charging, and if not, the cloud server does not do any operation, and the parking space guiding control does not do any operation. The vehicle stops into the correct parking space under the assistance of parking space guidance control, and the charging pile performs a plug-and-play charging program after the gun is inserted. And conventional charge state monitoring and charge fee metering are carried out in the charging process. After the charging is completed, the charging pile informs the cloud platform to carry out electric charge settlement, and a settlement account can be a bound fund account or a bank card or a rechargeable card in the OBU. Whether the radio frequency identification vehicle leaves the ground or not is judged, if the vehicle leaves the ground, the cloud server is informed of parking fee settlement, and if the vehicle does not leave the ground, the judgment is continued. After the vehicle leaves the ground and the cost is settled, the parking space guiding control closes the barrier gate or the ground lock, and the whole flow of charging is finished.
In summary, in the charging method according to the embodiment of the present invention, the radio frequency identification-based plug-and-play charging method supports the non-inductive payment, and the radio frequency identification technology confirms the identity information of the vehicle to implement the plug-and-play charging, so that the charging cost can be directly deducted after the charging is completed; the mobile phone reservation charging is supported by the plug-and-play charging mode based on the radio frequency identification, the parking space and the charging condition of the target charging station are obtained remotely through the mobile phone reservation function, the parking space and the charging service are reserved in advance, and the peak parking space and the charging shortage are avoided; the plug-and-play charging system based on radio frequency identification supports an anti-occupation function, a reserved parking space for charging is reserved through a mobile phone, and a vehicle can be allowed to enter only when the reserved vehicle reaches the parking space and is reserved through radio frequency identification; based On the plug-and-play charging mode based On radio frequency identification, the vehicle detection function is supported in the parking space, if a vehicle is in the radio frequency identification parking space, the OBU (On board Unit) or electronic license plate information can be read, and if no vehicle is in the radio frequency identification parking space, the OBU or electronic license plate information can not be identified.
