Based on the implementation environment shown in fig. 1, an embodiment of the present application provides a method for communication between a vehicle and a charging pile, as shown in fig. 2, where the method for communication between a vehicle and a charging pile may be performed by the vehicle and the charging pile, and the method includes steps 201-206.

Step 201, the charging pile establishes a service socket through the bluetooth communication device of the charging pile, and the charging pile monitors a connection signal of the vehicle according to the service socket.

The charging pile establishes a server socket through the Bluetooth communication equipment of the charging pile, a server socket function exists in a program of the Bluetooth communication equipment of the charging pile, the server socket function is a set of functions for creating the server socket, the type of the server socket needs to be specified in the process of creating the server socket through the server socket function, and a server IP (Internet Protocol ) address and a server port number. The server socket function specifies the server IP address and the server port number, i.e. informs the server on which server IP address and server port number to monitor the client's request. In the embodiment of the application, the type of the socket at the server is used for determining the data transmission mode between the server and the client to correspond to different actual requirements, the IP address at the server is used for identifying the address of the server in the network, and the port number at the server is used for identifying the port of a specific application program in the server.

By way of example, the charging stake of the present application is any charging stake that is equipped with a bluetooth communication device and is capable of establishing a server socket. The server socket refers to an interface for communication between different devices, and the devices for communication by means of the socket are respectively: client and server. The client is the end initiating the connection signal, and the server is the end receiving the call connection signal.

In the embodiment of the application, the charging pile is used as a service end, and the vehicle is used as a client. Before the client performs call connection, the server is in a monitoring state, and monitors whether the client requires to establish connection. The server socket established by the server receives the connection signal of the client, and the server executes corresponding program operation through the connection signal of the client. The connection signal of the client is sent to the charging pile by the vehicle through the client socket established by the Bluetooth communication equipment of the vehicle. The state of the charging pile is in a blocking state before the charging pile waits for the vehicle to send the connection signal, and the blocking state refers to that the charging pile waits for the vehicle to send the connection signal, and the charging pile can carry out subsequent operation after receiving the connection signal sent by the vehicle.

The follow-up operation comprises communication between the vehicle and the charging pile, the vehicle can send interactive vehicle information to the charging pile in the communication process of the vehicle and the charging pile, and the charging pile performs corresponding operation according to the vehicle information. The selection of the vehicle information depends on signal selection and state judgment of the whole vehicle system, the vehicle information is required to be screened before communication connection, and feasibility and convenience are required to be considered when the vehicle information of interaction between the vehicle and the charging pile is screened.

For example, the current electric quantity information of the vehicle is selected as the vehicle information, so that the charging time and the charging speed of the vehicle can be optimized, and the charging pile can automatically adjust the charging voltage and the charging current according to the current electric quantity and the charging requirement of the vehicle by determining the electric quantity condition of the vehicle, so as to achieve the best charging effect, thereby achieving the effects of shorter charging time and faster charging speed; and whether the fault information of the vehicle is selected as interaction data, and the charging pile judges whether to execute charging operation according to the fault information of the vehicle so as to avoid further damage to the vehicle in the charging process, and meanwhile, the state information of the vehicle can be sent to a charging pile background management system through the charging pile, so that the maintenance of the vehicle is facilitated.

In step 202, the vehicle establishes a client socket through the bluetooth communication device of the vehicle, and the vehicle sends a connection signal to the charging pile according to the client socket.

The vehicle establishes a client socket through the Bluetooth communication device of the vehicle, and as the server, the vehicle needs to establish a client socket through a client socket function, specify the type of the socket, connect the server IP address and the server port number of the server through a connection function, and send a connection signal to the server through the established client socket. In the embodiment of the application, the data content contained in the connection signal is not limited, and the server can perform corresponding reply operation on the connection signal after receiving the connection signal.

And 203, under the condition that the charging pile receives a connection signal sent by the vehicle according to the socket of the service end, the charging pile is in wireless connection with the vehicle.

After the charging pile receives a connection signal sent by the vehicle through a service end socket established by the charging pile, the blocking state of the charging pile is changed into a connection state, the charging pile establishes a connection socket through Bluetooth communication equipment of the charging pile, the connection socket is used for communicating with the vehicle, and the charging pile continues to execute monitoring operation through the service end socket established by the Bluetooth communication equipment of the charging pile. The charging pile is communicated with the vehicle through a connection socket established by Bluetooth communication equipment of the charging pile, and the charging pile detects whether the process of establishing connection with the vehicle is abnormal or not.

Illustratively, the charging stake transmits a connection confirmation message to the vehicle through the connection socket. Wherein the connection confirmation message indicates that the charging stake has successfully received the connection request of the vehicle and created a new connection with the vehicle through the connection socket. And after the vehicle receives the connection confirmation message sent by the charging pile through the connection socket, the vehicle communicates with the charging pile through the connection socket. If the charging pile successfully receives the connection request of the vehicle and sends a connection confirmation message to the vehicle, and the vehicle successfully receives the connection confirmation message sent by the charging pile, the vehicle and the charging pile are considered to be free of abnormality, and the vehicle and the charging pile are not abnormal, so that the vehicle and the charging pile are successfully connected.

In one possible implementation manner, the charging pile successfully receives the connection request of the vehicle as a first step, the charging pile sends a connection confirmation message to the vehicle as a second step, and the vehicle successfully receives the connection confirmation message sent by the charging pile as a third step, wherein at least one step is not normally executed, and the condition that at least one end of the vehicle and at least one end of the charging pile are abnormal is indicated, and the condition that the vehicle and the charging pile are connected in an abnormal manner is indicated. The embodiment of the application does not limit the reasons why at least one of the three steps is not normally executed, and whether the reasons cause the at least one of the three steps to be not normally executed indicates that at least one end of the vehicle and the charging pile is abnormal.

In step 204, after the wireless connection between the vehicle and the charging pile is successful, the vehicle sends the vehicle information to the charging pile in a wireless communication manner through the Bluetooth communication device of the vehicle.

After the wireless connection between the vehicle and the charging pile is successful, the vehicle and the charging pile perform wireless communication, the vehicle sends vehicle information to the charging pile, the charging pile sends charging pile information to the vehicle, and two-way wireless communication is established between the vehicle and the charging pile. The embodiment of the application does not limit the process of bidirectional wireless communication, and at least one of the charging pile and the vehicle sends information to the other side, so that the vehicle and the charging pile are considered to be in wireless communication operation.

In the wireless communication process of the vehicle and the charging pile, the vehicle encrypts the vehicle information to reduce the risk of vehicle information leakage, the encryption mode adopts a key encryption mode, the key is set by a charging pile background system and is divided into a vehicle key and a charging pile key, and the vehicle key and the charging pile key are identical or symmetrical so that the charging pile can adopt the charging pile key to decrypt the vehicle information encrypted by the vehicle key.

The vehicle sends vehicle information to the charging pile in a wireless communication manner through the bluetooth communication device of the vehicle, wherein the vehicle information is screened out through the combination of signal selection and state judgment of the whole vehicle system and feasibility and convenience principles in step 201.

If the vehicle information includes the current electric quantity information of the vehicle, the charging pile can know the current electric quantity condition of the vehicle through the received current electric quantity information of the vehicle, and the charging pile automatically adjusts the charging voltage and the charging current according to the current electric quantity of the vehicle so as to achieve the optimal charging effect, so that the charging time is shorter, the charging speed is faster, and the service life of the vehicle battery can be prolonged; if the vehicle information comprises the abnormal information of the vehicle, after the charging pile receives the abnormal information of the vehicle sent by the vehicle, the charging pile stores and judges whether the vehicle is abnormal, so that the charging pile can conveniently judge whether to execute the charging operation or not, and further damage to the vehicle in the charging process is avoided. After the charging pile judges the vehicle information, if the vehicle is not abnormal, the charging pile continues to execute wireless communication operation with the vehicle.

In step 205, when the charging pile determines that the vehicle is abnormal according to the vehicle information, the charging pile feeds back the vehicle information to the charging pile background system, and the charging pile sends the charging pile information to the vehicle in a wireless communication manner through the bluetooth communication device of the charging pile, wherein the charging pile information is used for reminding the driver of the vehicle of the condition of the charging pile.

Under the condition that the charging pile determines that the vehicle is abnormal according to the vehicle information, the charging pile feeds back the vehicle abnormality information to the charging pile background management system, and the charging pile is used as a basis for after-sales or daily maintenance of a background staff or a vehicle maintainer on the vehicle. Similarly, after the vehicle sends other vehicle information except the current electric quantity information and whether the vehicle is abnormal or not to the charging pile, the charging pile stores and judges the other vehicle information in the vehicle information. The embodiment of the application does not limit the mode of judging and processing other vehicle information contained in the vehicle information by the charging pile.

For example, if the other vehicle information includes vehicle battery temperature information, if the charging pile determines that the temperature of the vehicle battery is too high according to the vehicle battery temperature information, the charging pile may send warning information of the too high vehicle battery temperature to the vehicle through wireless communication. In the embodiment of the application, the form of the warning information for the excessive temperature of the battery of the vehicle is not limited, and the warning information can be displayed by sound or a vehicle display screen, so that the driver of the vehicle can be reminded.

The charging pile sends charging pile information such as whether the charging pile has faults or not to the vehicle in a wireless communication mode through Bluetooth communication equipment of the charging pile, and reminds a driver of the vehicle of the condition of the charging pile, wherein a pile management system of the charging pile collects the information of the charging pile and responds to the information sent to the charging pile by the vehicle. For example, when the vehicle sends vehicle battery temperature information to the charging stake, the stake management system executes the charging stake to send temperature warning information to the vehicle operation when the vehicle battery temperature exceeds a threshold temperature. The threshold temperature is the highest temperature that can not damage the vehicle when the vehicle battery is in operation.

Illustratively, the charging stake information wirelessly transmitted to the vehicle by the charging stake's bluetooth communication device includes: whether the charging pile is abnormal or not, the charging pile sends the abnormal information of the charging pile to the vehicle, the vehicle receives the abnormal information of the charging pile or not, the vehicle stores and judges whether the abnormal information of the charging pile or not, and when the vehicle judges that the charging pile is abnormal according to the information of the charging pile, the vehicle can perform charging operation through the charging pile, and then the vehicle and the charging pile continue to perform wireless communication operation. In the embodiment of the application, the abnormal condition of the charging pile is not limited, for example, the abnormal condition of the charging pile comprises the condition that the charging pile is occupied by other vehicles, the charging line of the charging pile is damaged, and the like, so that the charging pile cannot perform charging operation with the vehicles. If the charging pile is abnormal, the charging pile management system can inform the charging pile management personnel, and the charging pile management personnel can maintain the charging pile conveniently.

In step 206, if the condition of the charging pile is that the charging pile is abnormal or has been used by other vehicles, the charging pile notifies the vehicle to replace the charging pile.

Under the condition that the charging pile is abnormal or used by other vehicles, the charging pile can inform the vehicle of changing the charging pile, the informing mode is not limited, for example, the vehicle reminds a driver of changing other charging piles through a vehicle-mounted display screen or other modes, and the inconvenience that the driver of the vehicle can obtain information after swiping a card and inserting a gun can be avoided. Illustratively, the charging stake information wirelessly transmitted to the vehicle by the bluetooth communication device of the charging stake further includes: and the power information of the charging pile is sent to the vehicle by the charging pile, the vehicle receives the power information of the charging pile, the vehicle stores and matches the power information of the charging pile, if the power of the charging pile can be matched with the charging power of the vehicle, the vehicle displays the matching information, and if the power of the charging pile is not matched with the charging power of the vehicle, the vehicle displays the mismatching information, so that a driver of the vehicle is reminded of replacing the charging pile.

In a possible implementation manner, when the vehicle determines that the charging pile performing wireless communication with the vehicle is abnormal or is occupied by another vehicle according to the received charging pile information, the vehicle and the other charging piles within the coverage area of the bluetooth communication device of the vehicle perform wireless communication operation, where the manner in which the vehicle and the other charging piles establish wireless communication connection is the same as the method described in step 201, step 202 and step 203 in this embodiment, and will not be repeated here. If at least one charging pile can be matched with the vehicle and normally charges in the wireless communication process of the vehicle and other charging piles within the Bluetooth coverage range of the vehicle, the first charging pile which can be matched with the vehicle can send the number or position information of the first charging pile to the vehicle in a wireless communication mode, and the vehicle informs a driver to drive the vehicle to search the position of the charging pile after receiving the number or position information of the first charging pile. The application does not limit the mode that the vehicle informs the driver to drive the vehicle to find the position of the charging pile, for example, the notification information is played through voice, or the notification information is displayed through the display screen of the vehicle.

If, in the wireless communication process between the vehicle and the other charging piles within the bluetooth communication range of the vehicle, the other charging piles within the bluetooth communication range of the vehicle cannot be matched with the vehicle and perform normal charging operation, the vehicle establishes wireless communication connection through any charging pile capable of performing wireless connection between the bluetooth communication device of the vehicle and any charging pile capable of performing wireless connection within the bluetooth communication range of the vehicle in the manner described in step 201, step 202 and step 203 in the embodiment of the present application, and any charging pile capable of performing wireless connection between the vehicle is referred to as a first relay charging pile, where the first relay charging pile is capable of communicating with the other charging piles outside the bluetooth communication device coverage of the vehicle, and in the embodiment of the present application, the communication manner between the first relay charging pile and the other charging piles is not limited as long as the first relay charging pile is capable of communicating with the other charging piles.

For example, the first relay charging stake transmits the communication information to the charging station system, which transmits the communication information to the other charging stake.

The embodiment of the application does not limit how many second relay charging piles exist between the first relay charging pile and other charging piles, and only needs to enable any two sides of the first relay charging pile, other charging piles and the charging station system to communicate through the existing second relay charging piles. In the process of communication between any two sides of the first relay charging pile, other charging piles and the charging station system, the second charging pile which can be matched with the vehicle and is subjected to charging operation is screened out through the first relay charging pile or the charging station system. The embodiment of the application does not limit the mode of screening the second charging pile.

The vehicle informs the driver to drive the vehicle to find the location of the second charging stake. The application does not limit the mode that the vehicle informs the driver to drive the vehicle to find the position of the charging pile, for example, the notification information is played through voice, or the notification information is displayed through the display screen of the vehicle. After the driver of the vehicle drives the vehicle and changes to the second charging pile, the vehicle establishes wireless connection with the second charging pile, and the step of establishing wireless connection between the vehicle and the second charging pile can refer to the step of establishing wireless connection between the vehicle and the charging pile, which is not described herein.

In the case where the wireless communication between the vehicle and the charging pile is completed, the wireless communication between the vehicle and the charging pile is disconnected. If the disconnection operation is normal, when the wireless communication is completed or the vehicle actively requests the disconnection, the normal disconnection operation needs to be performed. At least one of the vehicles or the charging piles needs to send a corresponding disconnection signal to the other party through wireless communication between the charging piles and the vehicles, after the at least one of the vehicles or the charging piles receives the disconnection signal, if the at least one of the vehicles or the charging piles determines that the other party is ready for disconnection according to the disconnection signal and no vehicle information or charging pile information which needs to be sent to the other party exists, the at least one of the vehicles or the charging piles sends a reply disconnection signal to the other party, and after the at least one of the vehicles or the charging piles receives the reply disconnection signal sent by the other party, the at least one of the vehicles or the charging piles performs disconnection operation, so that wireless communication between the two parties is disconnected.
