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.

The data processing method can be interactively executed by the vehicle-mounted equipment and the terminal equipment. As shown in fig. 1, the data processing method may include, but is not limited to, the following steps:

s101, acquiring a verification data packet of an application program of the vehicle-mounted device and an update data packet of the application program of the vehicle-mounted device.

Specifically, the vehicle-mounted device may acquire a verification data packet of the application program of the vehicle-mounted device, and acquire an update data packet of the application program of the vehicle-mounted device, where the verification data packet may be used to verify validity of the update data packet of the application program of the vehicle-mounted device. The verification data packet may be a database that is sent to the vehicle-mounted device in advance by the terminal device and stored in the vehicle-mounted device, and the vehicle-mounted device may be directly obtained from the database of the vehicle-mounted device. The check packet may be a check packet that the terminal device transmits to the in-vehicle device before transmitting the update packet of the application program in the in-vehicle device to the in-vehicle device, or may be a check packet that the terminal device transmits to the in-vehicle device together with transmitting the update packet of the application program in the in-vehicle device to the in-vehicle device.

Optionally, the vehicle-mounted device may request a verification data packet for verifying an update data packet of an application program of the vehicle-mounted device from the terminal device, and when the vehicle-mounted device acquires the verification data packet, acquire the update data packet of the application program of the vehicle-mounted device from the terminal device through a direct communication connection. In this way, only after the vehicle-mounted device receives the verification data packet, the update data packet of the application program of the vehicle-mounted device is obtained from the terminal device, so that the problem that the validity of the update data packet of the application program of the vehicle-mounted device cannot be verified when the verification data packet is not received can be avoided.

Optionally, the vehicle-mounted device may establish a direct communication connection between the vehicle-mounted device and the terminal device, so that data interaction between the vehicle-mounted device and the terminal device may be performed through the direct communication connection, for example, the vehicle-mounted device receives a verification data packet sent by the terminal device through the direct communication connection. The direct communication connection is a communication mode, so that data can be directly transmitted between two interactive parties without forwarding by a third party (such as a base station). It can be understood that after the direct communication connection is established between the vehicle-mounted equipment and the terminal equipment, the vehicle-mounted equipment and the terminal equipment can directly perform data communication, so that the data transmission safety between the vehicle-mounted equipment and the terminal equipment can be improved, and meanwhile, the data transmission rate can be improved, the transmission time can be shortened, and the energy consumption can be reduced. Wherein the direct communication connection may include, but is not limited to, a bluetooth connection near field communication (Near Field communication, NFC) connection, an ultrasonic connection, an electromagnetic wave connection, an infrared connection, and the like. The communication data format protocol session constraint can be carried out between the vehicle-mounted equipment and the terminal equipment so as to agree on the communication rules between the two communication parties. Wherein, the terminal device may include: smart terminals with data processing functions such as smart phones, tablet computers, notebook computers, desktop computers, wearable devices, smart home and head-mounted devices.

Optionally, the direct communication connection may be a bluetooth connection, and specific content of establishing the direct communication connection between the vehicle device and the terminal device may include: generating a network connection request, wherein the network connection request carries a Bluetooth identifier and a Bluetooth connection protocol corresponding to Bluetooth in the vehicle-mounted equipment. And sending a network connection request to the terminal equipment, and receiving a network connection response message sent by the terminal equipment, wherein the network connection response message is generated based on the network connection request when the terminal equipment receives the network connection request. And establishing direct communication connection between the vehicle-mounted equipment and the terminal equipment through Bluetooth of the vehicle-mounted equipment according to the network connection response message.

Specifically, the vehicle-mounted device acquires a bluetooth identifier and a bluetooth connection protocol corresponding to bluetooth in the vehicle-mounted device, and further, the vehicle-mounted device can send a network connection request to the terminal device according to a network connection request generated by the bluetooth identifier and the bluetooth connection protocol. The terminal equipment can scan the network connection request, and after the terminal equipment scans the network connection request of the vehicle-mounted equipment, the terminal equipment can receive the network connection request, and generates a network connection response message according to the network connection request of the vehicle-mounted equipment so as to determine that direct communication connection is established with the vehicle-mounted equipment. Further, the terminal device may send the network connection reply message to the vehicle-mounted device, and the vehicle-mounted device may receive the network connection reply message sent by the terminal device. And establishing direct communication connection between the vehicle-mounted equipment and the terminal equipment through Bluetooth in the vehicle-mounted equipment according to the network connection response message. The bluetooth in the vehicle-mounted device may be bluetooth of the vehicle-mounted device, or may be bluetooth of an upgrade device connected to the vehicle-mounted device. Specifically, when the bluetooth in the vehicle-mounted device is the bluetooth of the vehicle-mounted device, the bluetooth identifier and the bluetooth connection protocol of the bluetooth of the vehicle-mounted device can be obtained through upgrading application in the vehicle-mounted device, and a network connection request is generated according to the bluetooth identifier and the bluetooth connection protocol of the bluetooth of the vehicle-mounted device. When the Bluetooth in the vehicle-mounted equipment is the Bluetooth accessed to the upgrading device in the vehicle-mounted equipment, the network connection request can be generated by accessing the upgrading device in the vehicle-mounted equipment according to the Bluetooth identifier and the Bluetooth connection protocol of the Bluetooth of the upgrading device.

Specifically, the vehicle-mounted device may broadcast the network connection request generated according to the bluetooth identifier and the bluetooth connection protocol of the vehicle-mounted device through the broadcasting service of bluetooth. The terminal equipment can acquire a target Bluetooth identifier (namely, a Bluetooth identifier of the vehicle-mounted equipment) to be connected, and if the terminal equipment determines that the Bluetooth identifier (namely, the Bluetooth identifier of the vehicle-mounted equipment) carried in the received network connection request is the target Bluetooth identifier, the terminal equipment establishes Bluetooth connection with the vehicle-mounted equipment according to the Bluetooth identifier of the vehicle-mounted equipment. After the terminal equipment determines that Bluetooth connection is established with the vehicle-mounted equipment, a communication channel between the vehicle-mounted equipment and the terminal equipment is established by acquiring a Bluetooth connection protocol of the vehicle-mounted equipment, and then a direct communication channel between the vehicle-mounted equipment and the terminal equipment is established by Bluetooth of the terminal equipment and Bluetooth of the vehicle-mounted equipment.

Optionally, after the direct communication connection is established between the vehicle-mounted device and the terminal device, a specific manner of the vehicle-mounted device obtaining the update data packet of the application program of the vehicle-mounted device may include: the communication status check data packet may be obtained from the terminal device via a direct communication connection. And acquiring the data receiving state of the vehicle-mounted equipment, generating a state indicating value for reflecting the data receiving state of the vehicle-mounted equipment, and adding the state indicating value into the communication state check data packet when the state indicating value is a valid value to obtain a communication state response message. And sending the communication state response message to the terminal equipment through direct communication connection, and acquiring the update data packet from the terminal equipment.

Specifically, after the direct communication connection is established between the vehicle-mounted device and the terminal device, the terminal device may generate a communication status check packet for checking whether the vehicle-mounted device is in an acceptable state (i.e., the vehicle-mounted device is in a state in which it can receive data of the terminal device). After the terminal device generates the communication state check data packet, the communication state check data packet can be sent to the vehicle-mounted device through direct communication connection. The vehicle-mounted equipment receives the communication state check data packet sent by the terminal equipment through direct communication connection, and further, the vehicle-mounted equipment can acquire the data connection state of the vehicle-mounted equipment to generate a state indication value for reflecting the data receiving state of the vehicle-mounted equipment. The status indication value is used for reflecting the data receiving status of the vehicle-mounted equipment, and if the status indication value is 1, the data receiving status of the vehicle-mounted equipment is indicated to be in a receivable status (namely, the vehicle-mounted equipment can receive the data sent by the terminal equipment); when the status indication value is 0, the data receiving status of the in-vehicle apparatus is indicated as an unreceivable status (i.e., the in-vehicle apparatus cannot receive the data transmitted by the terminal apparatus). Further, when the status indication value is an effective value, the vehicle-mounted device may add the status indication value to the communication status check data packet to obtain a communication status response message, and send the communication status response message to the terminal device through direct communication connection, so as to obtain the update data packet from the terminal device. The terminal equipment can receive a communication state response message returned by the vehicle-mounted equipment through direct communication connection, wherein the communication state response message is used for indicating the terminal equipment to allow the vehicle-mounted equipment to acquire an update data packet when a state indication value is an effective value; when the status indication value is a valid value, the status indication value reflects that the data receiving status of the in-vehicle device is a receivable status. If the in-vehicle device directly transmits to the terminal device communication status response information including a status indication value (that is, the status indication value may be 0 or 1), the communication status response information indicates that the terminal device is not allowed to acquire the update packet when the status indication value is an invalid value, and reflects that the data reception status of the in-vehicle device is an unreceivable status when the status indication value is an invalid value.

Specifically, when the in-vehicle apparatus generates a status indication value for reflecting the data reception status of the in-vehicle apparatus, the field description information of the status check field, which is a field for describing the data reception status of the in-vehicle apparatus, may be acquired from the communication status check packet. Further, the in-vehicle apparatus may generate a status indication value reflecting the data reception status of the in-vehicle apparatus from the field description information of the status check field and the data reception status of the in-vehicle apparatus. For example, the field description information of the field check field is: if the data receiving state of the vehicle-mounted equipment is an acceptable state, the state indication value is 1; if the data reception state of the in-vehicle apparatus is an unacceptable state, the status instruction value is 0. Then, when the data reception state of the in-vehicle apparatus is the receivable state, the status instruction value is 1; when the data reception state of the in-vehicle apparatus is the non-receivable state, the status indication value is 0.

Specifically, as shown in table 1, table 1 is a definition rule of a communication status check packet, and as shown in table 1, the field check field is "xor check 1 byte", and the field description information of the field check field is: the abnormal state indication value is 0 (i.e., if the data reception state of the in-vehicle apparatus is an unacceptable state), or the state indication value is 1 (i.e., if the data reception state of the in-vehicle apparatus is an acceptable state). When the terminal device times out and does not receive a response message (i.e. a communication state response message) or the response message is wrong (i.e. transmission fails), the processing of retransmitting for 3 times at most is needed. The retransmission time interval is 100 ms, 300 ms, 600 ms. And if the terminal equipment does not receive a response after timeout for 2 seconds, the terminal equipment considers failure, and the Bluetooth connection is disconnected to carry out updating processing again. The normal time interval of the in-vehicle device during transmission is fixed at 50 milliseconds.

TABLE 1

Specifically, the vehicle-mounted device may obtain, from the terminal device, a verification data packet for verifying an update packet of an application program of the vehicle-mounted device through a direct communication connection. The update data packet of the application program of the vehicle-mounted device is used for carrying out iterative update (i.e. upgrading) on the application program in the vehicle-mounted device, so that the defect of the application program in the vehicle-mounted device can be repaired, and new program application can be pushed to enrich the application functions of the vehicle-mounted device, so that better business service is provided for users. The verification data packet of the update data packet is a data verification protocol, and is used for verifying the validity of the update data packet, for example, whether the update data packet is complete, whether the content is tampered, and the like can be verified through the verification data packet. The verification data packet of the update data packet is obtained through direct communication connection, so that the obtaining safety of the verification data packet can be improved.

Specifically, if the vehicle-mounted device acquires the verification data packet sent by the terminal device, the vehicle-mounted device can acquire the update data packet of the application program of the vehicle-mounted device from the terminal device through direct communication connection. After receiving the check data packet sent by the terminal device, the vehicle-mounted device may return a receiving response message for the check data packet to the terminal device, so as to notify the terminal device that the vehicle-mounted device has received the check data packet. After the terminal device sends the check data packet to the vehicle-mounted device, if the receiving response message for the check data packet returned by the vehicle-mounted device is not received within a first preset duration, the vehicle-mounted device is determined to not receive the check data packet, and the check data packet is sent to the vehicle-mounted device again through direct communication connection. After encrypting the update data packet, the terminal device sends the encrypted update data packet to the vehicle-mounted device.

Specifically, if the vehicle-mounted device receives the check data packet, the vehicle-mounted device may send a receiving response message for the check data packet to the terminal device through the direct communication channel, and after the terminal device receives the receiving response message for the check data packet sent by the vehicle-mounted device, the vehicle-mounted device may send an update data packet of an application program of the vehicle-mounted device to the vehicle-mounted device through direct communication connection. Specifically, if the vehicle-mounted device receives the check data packet, a receiving response message for the check data packet may be sent to the terminal device through the direct communication channel, and at the same time, the vehicle-mounted device sends an acquisition request for the update data packet of the application program in the vehicle-mounted device to the terminal device under the condition that the vehicle-mounted device is ready to acquire the update data packet. The terminal equipment receives an acquisition request about an update data packet of an application program in the vehicle-mounted equipment, which is sent by the vehicle-mounted equipment, and sends the update data packet of the application program in the vehicle-mounted equipment to the vehicle-mounted equipment through a direct communication channel when the vehicle-mounted equipment is in a receivable state. In this way, only after the vehicle-mounted device receives the verification data packet, the update data packet of the application program of the vehicle-mounted device is obtained from the terminal device, so that the problem that the validity of the update data packet of the application program of the vehicle-mounted device cannot be verified when the verification data packet is not received can be avoided.

Optionally, the specific manner of acquiring the update data packet from the terminal device by the vehicle-mounted device may include: acquiring equipment attribute information of the vehicle-mounted equipment, and generating an update data packet acquisition request carrying the equipment attribute information. And sending the update data acquisition request to the terminal equipment through direct communication connection. Receiving an update data packet of an application program of the vehicle-mounted equipment returned by the terminal equipment through direct communication connection; the update data packet is matched with the equipment attribute information carried by the update data acquisition request.

Specifically, the vehicle-mounted device may acquire device attribute information of the vehicle-mounted device, where the device attribute information may include a device identifier, a device manufacturer, a device model, and the like. The vehicle-mounted device can also generate an update data packet acquisition request carrying device attribute information, and send the update data packet acquisition request to the terminal device through direct communication connection. After receiving an update data packet acquisition request carrying device attribute information sent by the vehicle-mounted device, the terminal device can acquire an update database, wherein the update database comprises M candidate update data packets and configuration protocol files corresponding to each candidate update data packet, the configuration protocol files are used for indicating attribute information corresponding to the corresponding candidate update data packet, M is a positive integer, and if M can take the values of 1,2 and 3 …. Further, the terminal device may acquire, from the update database, a candidate update packet whose attribute information matches the device attribute information as an update packet of the application program of the in-vehicle device. The terminal device can send the update data packet of the application program of the vehicle-mounted device to the vehicle-mounted device through direct communication connection. For example, if the device model of the in-vehicle device is X123, the terminal device may acquire, from the update database, a candidate update packet having attribute information of X123 as an update packet of an application program of the in-vehicle device according to the device model X123. In this way, the vehicle-mounted device directly acquires the update data packet corresponding to the vehicle-mounted device from the terminal device, so that the update data packet of the application program of the vehicle-mounted device can be quickly acquired, the data quantity of data transmission can be reduced, and the acquisition efficiency of the update data packet is improved. The terminal device may parse attribute information corresponding to each candidate update data packet according to the configuration protocol file.

Optionally, the terminal device may send the M candidate update data packets in the update database and the configuration protocol file corresponding to each candidate update data packet to the vehicle-mounted device through direct communication connection, and after the vehicle-mounted device receives the M candidate update data packets and the configuration protocol file corresponding to each candidate update data packet, the device attribute information of the vehicle-mounted device may be obtained. And acquiring candidate update data packets with attribute information matched with the equipment attribute information from the M candidate update data packets according to the configuration protocol file corresponding to each update data packet, wherein the candidate update data packets are used as update data packets of application programs of the vehicle-mounted equipment. In this way, the vehicle-mounted device can acquire the update data packet of the application program in the vehicle-mounted device at one time, and the update data packet is prevented from being acquired from the terminal device for multiple times.

S102, verifying the validity of the update data packet according to the verification data packet to obtain a verification result.

Specifically, after the vehicle-mounted device acquires the update data packet, the validity of the update data packet may be verified according to the verification data packet to obtain a verification result, where the verification result may include that the update data packet has validity, or that the update data packet does not have validity. In this way, by verifying the update package, the validity of the update package can be ensured, and further, the update of the application program in the in-vehicle device according to the update package having the validity can be ensured.

Optionally, the vehicle-mounted device may verify the integrity of the update data packet according to the check data packet, and if the update data packet is determined to have no integrity according to the check data packet, determine that the update data packet has no validity; and if the updating data packet is determined to have the integrity according to the checking data packet, determining that the updating data packet has the validity. For example, the check data packet indicates that the update data packet has P bytes, and if the update data packet is P bytes, the update data packet is determined to have integrity; if the update data packet is not P bytes, it is determined that the update data packet does not have integrity.

Optionally, the vehicle-mounted device may verify the correctness of the update data packet according to the check data packet, and if the update data packet is determined to be inaccurate (i.e. the content is tampered) according to the check data packet, determine that the update data packet does not have validity; if the update data packet is determined to have accuracy (i.e. the content is not tampered) according to the check data packet, the update data packet is determined to have validity. For example, if the code value indicated in the check data packet is Q and the code value obtained by the vehicle-mounted device for coding the update data packet is not Q, determining that the update data packet is inaccurate; if the obtained code value is Q, the updated data packet is determined to be accurate.

And S103, if the verification result indicates that the update data packet has validity, updating the application program of the vehicle-mounted equipment according to the update data packet.

Specifically, if the vehicle-mounted device determines that the verification result indicates that the update data packet has validity, the application program in the vehicle-mounted device is updated according to the update data packet, so that the defect of the application program in the vehicle-mounted device can be repaired, and new program application can be pushed to enrich the application functions of the vehicle-mounted device, so that better business service is provided for a user.
