The identification module is installed on the street lamp and used for identifying the electric automobile and outputting an identification signal. Specifically, the identification module comprises a positioning unit and a wireless connection unit, and the identification module is wirelessly connected with the electric automobile through the wireless connection unit. The wireless connection module can be an RFID module, an NFC module or a Bluetooth module, and is connected with the electric automobile through a near field communication technology, the wireless connection module is not limited uniquely, the electric automobile can be connected and the connection state can be identified, and the wireless connection module is preferably a Bluetooth module. Certainly, in order to be wirelessly connected with the wireless connection unit, the electric vehicle itself needs to be configured with a communication module matched with the bluetooth module, and can only be connected with one wireless connection unit at a time, which is not described herein again.
It should be noted that, in order to ensure that the location of the electric vehicle identified by the identification module is indeed within the wireless charging range of the street lamp, the wireless connection distance of the wireless connection unit is smaller than the charging action range of the wireless charging transmission module.
The positioning unit is used for positioning the street lamp and outputting a positioning signal representing the position of the street lamp. The street lamps arranged on one side of the road in a single row are matched with unique codes, in order to simplify the setting mode of the positioning unit and reduce the setting cost of the positioning unit, the positioning unit is arranged as a code storage unit, and the positioning signals output by the positioning unit are the coded data matched with the street lamps. When the wireless connection unit is wirelessly connected with the electric automobile, the identification signal output by the identification module comprises a positioning signal.
The data processing module comprises a speed calculating module, a distance calculating module and a time calculating module. When the identification module identifies that the electric automobile enters the charging range of the street lamp, the identification module outputs an identification signal to the data processing module, and the speed calculation module calculates the running speed of the electric automobile according to the coded data in the identification signal; the distance calculation module calculates the budget distance between the electric automobile and the current street lamp according to the coded data; the time calculation module is used for calculating the estimated time of the electric automobile reaching the range of the current street lamp according to the driving speed and the estimated distance. The data processing modules in the adjacent street lamps are in wired communication connection, preferably, the data processing modules are communicated with one another by adopting a 485 communication protocol.
In order to simplify the calculation of the driving speed and the estimated distance, the data processing module stores a preset unit distance, the preset unit distance is the average distance between adjacent street lamps, the estimated distance is the product of the preset unit distance and the number of the street lamps between the current street lamp and the street lamp where the electric automobile is located, and the driving speed is data obtained by dividing the preset unit distance by the time taken by the electric automobile to drive from the previous street lamp to the current street lamp position. The data processing module forms transmission data by the coded data, the driving speed data and the transition data output by the identification module connected with the data processing module and sends the transmission data to the data processing module of the target street lamp, the target street lamp is a street lamp which is positioned behind the street lamp where the identification module is positioned along the standard driving direction of the road where the street lamp is positioned, the standard driving direction is the direction indicated by a hollow arrow in figure 1, the transition data is gradually reduced along with the transmission times of the transmission data, and the transmission of the transmission data is stopped when the preset transition data in the transmission data received by the data processing module is zero.
As shown in fig. 1, the three street lamps are sequentially arranged along the power standard driving direction, and the numbers are respectively 10, 15 and 20, four street lamps of No. 11-14 are further arranged between the street lamp of No. 10 and the street lamp of No. 15, and four street lamps of No. 16-20 are further arranged between the street lamp of No. 15 and the street lamp of No. 20.

And after receiving the transmission data, the data processing module in each target street lamp calculates the budget distance and the budget time, wherein the budget distance calculated by the No. 20 street lamp is 9 times of the preset unit distance, and the budget time is the budget distance divided by the driving speed in the transmission data.
And in the driving process of the electric automobile, each target street lamp calculates the estimated time and the estimated distance according to the latest transmission data.
And after the data processing module calculates the budget time, transmitting the budget time to the switching module. The switching module is arranged on a power supply loop of the wireless charging transmitting module, and controls the wireless charging transmitting module to be electrified when the budget time is greater than or equal to a lowest preset threshold and is lower than a highest preset threshold. The lowest preset threshold is zero, and the highest preset threshold is the maximum preset time set according to the preset unit distance. Certainly, when the identification module of the street lamp identifies that the street lamp enters the charging range of the current street lamp, the data processing module transmits the identification signal to the switching module, and the switching module receives the identification signal and then controls the wireless charging transmitting module to be electrified. When the data processing module does not receive the identification signal within the preset time, a disconnection signal is output, and the switching module receives the disconnection signal and then controls the wireless charging transmitting module to be powered off.
The power module comprises a mains supply connection unit and a photovoltaic power generation unit, namely, the wireless charging system is powered by adopting a hybrid power supply mode of mains supply and photovoltaic power generation, and specific details of power supply of the power module are not limited herein.
From the above, it can be seen that: when the street lamp discerns that electric automobile enters into self charging range, the target street lamp that is located the street lamp rear can calculate electric automobile and go to the time that corresponds the target street lamp, if the time of using is less than the biggest time of predetermineeing, then control wireless transmitting module that charges circular telegram to avoid wireless transmitting module frequently to cut off the power supply with in the short time, prolonged wireless charging system's life.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
