Detailed Description

In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

The embodiment provides a quick positioning based pre-charging system which comprises a charging pile terminal, a user mobile terminal and a server. The stake end of charging includes that a plurality of fills electric pile, every fills electric pile and all includes two rifle that charges, rifle A and the rifle B that charges promptly, equal fixed mounting has the location label in the handle of every rifle that charges, this location label can acquire the charging parameter information and the positional information who correspond the rifle that charges to with these information routing to the electric pile that fills that corresponds, fill electric pile and again with these information routing to server, make the server can acquire the charging parameter information and the positional information of the rifle that charges on all fill electric pile. The user needing charging can input charging parameter information matched with the vehicle in the user mobile terminal and send the charging parameter information to the server through the user mobile terminal, after the server receives the charging parameter information sent by the user mobile terminal, the server searches the position information of the charging gun with the same charging parameter information and sends the position information to the user mobile terminal, and therefore the user can quickly search the matched charging gun for charging. It should be noted that the user mobile terminal may be a mobile phone or a vehicle-mounted computer, and the charging parameter may be input in an APP in the mobile phone or the vehicle-mounted computer.

The positioning tag comprises a main control module, a positioning module and a power supply module. The power supply module is electrically connected with the main control module and the positioning module and supplies power to the positioning module and the power supply module. The main control module is also electrically connected with the positioning module. The positioning module can be controlled by the main control module, positions the charging gun at the position and sends the position information to the main control module. The main control module can acquire charging parameter information of the charging gun, and sends the acquired charging parameter information and the received position information to the corresponding charging pile. The charging parameters of the charging gun include a charging voltage, an output current, a rated power, and the like. In addition, when the charging pile dynamically distributes new charging parameters to the charging gun, the positioning tag can acquire the latest charging parameters of the charging gun in real time.

The master control module comprises a master control chip with the model number NRF 52832. The positioning module comprises a UWB module, in addition, three positioning base stations are fixedly arranged in the area where the charging pile is located, each positioning base station comprises a base station UWB module, a base station main control module, a GPRS wireless communication module and a power supply module, and the power supply module is electrically connected with the base station UWB module, the base station main control module and the GPRS wireless communication module and supplies power with the power supply module. The base station main control module is also electrically connected with the base station UWB module and the GPRS wireless communication module. The base station main control module can control the base station UWB module to communicate with the UWB module in the positioning label. The distance between the positioning tag and each positioning base station can be calculated through the communication time and the signal transmission rate of the UWB module in the positioning tag and the UWB modules of the base stations in the three positioning base stations, then through mutual transmission of information between the three positioning base stations, a point can be determined through the three distances, the point is the accurate position of the positioning tag, and finally, the base station main control module controls the GPRS wireless communication module to send the position information to the server. See figure 2 for a detailed schematic. UWB modules in the positioning tags and base station UWB modules both contain high-frequency counters, and positioning accuracy reaches the centimeter level. The base station main control module also comprises a main control chip with the model number of NRF 52832.

In addition, every fills electric pile and disposes three parking stall, is parking stall 1, parking stall 2 and parking stall 3 respectively, refers to fig. 3, and rifle A's that charges cable length can supply in rifle A extends parking stall 1 and parking stall 2, and rifle B's that charges cable length can supply to charge rifle B and extend in parking stall 2 and parking stall 3.

The charging parameter that needs when the user can only with the charging parameter phase-match of rifle A that charges, and the rifle A that charges when just charging the vehicle in the parking stall 1, the location label in the rifle A that charges can pinpoint rifle A's position to send to the server through filling electric pile, the server can judge according to the positional information of the rifle that charges that receives that rifle A that charges is extending parking stall 1 at present, the server can send information to user mobile terminal this moment, remind the user that rifle A that charges is being occupied. Meanwhile, the server can judge whether the charging gun A is in a state of charging the vehicle according to the running state of the charging gun A, so that whether the vehicle connected with the charging gun A is charged is judged. If the charging gun A is not in the running state, the vehicle is indicated to be charged, the server can acquire the information of the vehicle owner according to the vehicle information connected with the charging gun A at the moment, then the vehicle owner is contacted to move, a subsequent user can conveniently charge, and the problem that the unused charging pile occupies is avoided.

The embodiment also provides a pre-charging method of a pre-charging system based on quick positioning, which comprises the following steps:

step S1: inputting charging parameter information needing to be matched at a user mobile terminal;

step S2: the server searches whether the charging pile end has a charging gun matched with the charging parameter information, if so, the step S3 is carried out, and if not, the searching is continued;

step S3: the server acquires position information corresponding to the charging gun, and judges whether the charging gun is located at an initial position in the charging pile or not according to the position information of the charging gun, if so, the user moves the vehicle to a parking space adjacent to the corresponding charging gun for charging, and if not, the step S4 is carried out;

step S4: the server judges whether the corresponding charging gun is in the running state, if so, the step S2 is returned to; if not, the server acquires corresponding user information according to the vehicle information connected with the corresponding charging pile, and the server contacts the user to perform vehicle moving processing;

step S5: the user moves the vehicle to the parking space adjacent to the corresponding charging gun for charging.

According to the invention, the charging parameter information and the position information of the charging gun are obtained through the positioning tag and are sent to the server through the charging pile, a user can input the charging parameter information required by the vehicle and send the charging parameter information to the server, and the server searches the position information of the charging pile with the corresponding charging parameter information and sends the position information to the user, so that the user can quickly search the matched charging gun for charging.
