In the embodiment of the present invention, after receiving the sleep notification sent by the system chip, the network access device establishes a long connection (i.e., a first long connection) with the cloud server based on the first preset communication protocol.
103. After receiving the wake-up message sent by the cloud server through the first long connection, the network access device wakes up the system chip.
The wake-up message is compiled by the cloud server based on a first preset communication protocol.
In the embodiment of the invention, when the cloud server needs to issue the vehicle control instruction to the system chip, the cloud server compiles the wake-up message based on the first preset communication protocol and sends the wake-up message to the network access equipment through the first long connection with the network access equipment; after receiving the wake-up message sent by the cloud server through the first long connection, the network access device can wake up the system chip, so that the system chip enters a wake-up state from a dormant state.
Specifically, in this step, the network access device may send a wake-up notification to the system chip through its own virtual network card to wake up the system chip, but is not limited thereto.
Further, in the embodiment of the present invention, when the cloud server compiles the wake-up packet based on the first preset communication protocol, the cloud server may further add a wake-up request identification code in a variable header of the wake-up packet; after receiving the wake-up packet, the network access device also needs to record the wake-up request identifier included in the wake-up packet into a local log, so as to query the wake-up record in the following.
104. The system chip establishes a second long connection with the cloud server based on a second preset communication protocol so that the cloud server sends the vehicle control command to the system chip through the second long connection.
The second preset communication protocol specifically comprises the following steps: message queue Telemetry Transport protocol (MQTT), the second long connection is specifically: MQTT long links.

Specifically, in this step, the system chip may establish a second long connection with the cloud server through a preset program, where the preset program is specifically an IOT-Service program, but is not limited thereto.
Compared with the prior art that the efficiency of a mode that a cloud server sends a wake-up short message to a network access device to wake up the system chip and establish long connection with the cloud server is low, the method for waking up the system chip provided by the embodiment of the invention sends a sleep notification to the network access device by the system chip when a preset sleep moment is reached or a sleep instruction is received, and enters a sleep state; the network access equipment establishes a first long connection with a cloud server based on a first preset communication protocol after receiving a sleep notification sent by a system chip, and wakes up the system chip after receiving a wake-up message sent by the cloud server through the first long connection; after the system chip enters the awakening state, a second long connection is established with the cloud server based on a second preset communication protocol, so that the cloud server sends the vehicle control command to the system chip through the second long connection. Because the network access device can establish long connection with the cloud server after the system chip enters the dormant state, when the cloud server needs to issue a vehicle control instruction to the system chip, the cloud server can send a wake-up message to the network access device through the long connection with the network access device at the first time so as to wake up the system chip and establish the long connection with the cloud server, and therefore the efficiency of establishing the long connection between the wake-up system chip and the cloud server can be effectively improved.

202. After receiving the dormancy notification, the network access device establishes a first long connection with the cloud server based on a first preset communication protocol.
In the embodiment of the invention, after receiving the dormancy notification sent by the system chip, the network access equipment establishes a first long connection with the cloud server based on a first preset communication protocol. The following describes how the network access device establishes the first long connection with the cloud server based on the first preset communication protocol.
(1) The network access equipment sends an establishment message to the cloud server based on the first preset communication protocol.
The message is established by the network access equipment and compiled based on a first preset communication protocol.
In the embodiment of the invention, after receiving the sleep notification sent by the system chip, the network access device firstly needs to compile an establishment message based on a first preset communication protocol, and then sends the compiled establishment message to the cloud server.
Further, in the embodiment of the present invention, when the network access device writes the establishment packet based on the first preset communication protocol, the network access device further needs to perform signature processing on the identification code corresponding to the vehicle to which the network access device belongs by using a preset signature key to generate a digital signature, and add the generated digital signature to the variable header of the establishment packet, so that the cloud server verifies the identity of the network access device based on the digital signature included in the establishment packet to determine whether to establish a long connection with the network access device, where the identification code corresponding to the vehicle to which the network access device belongs may be, but is not limited to: a VIN code (Vehicle Identification Number) or an engine code corresponding to a Vehicle to which the network access device belongs.
(2) After receiving the confirmation message fed back by the cloud server, the network access device establishes a first long connection with the cloud server.
The confirmation message is compiled by the cloud server based on a first preset communication protocol.
In the embodiment of the present invention, after receiving the establishment message sent by the network access device, the cloud server compiles a confirmation message based on the first preset communication protocol and feeds back the compiled confirmation message to the network access device, and after receiving the confirmation message fed back by the cloud server, the network access device can successfully establish a long connection (i.e., a first long connection) with the cloud server.
Further, in the embodiment of the present invention, when the establishment message sent by the network access device to the cloud server includes the digital signature, after receiving the establishment message sent by the network access device, the cloud server further needs to verify the identity of the network access device based on the digital signature: decrypting the digital signature by using a preset signature key to obtain an identity code corresponding to a vehicle to which the network access equipment belongs, judging whether the identity code corresponding to the vehicle to which the network access equipment belongs is in a white list, if so, judging that the verification is successful, and at the moment, the cloud server needs to compile a confirmation message based on a first preset communication protocol and feed the compiled confirmation message back to the network access equipment; if not, the verification is judged to be failed, and at the moment, the cloud server needs to send error reporting information to the network access equipment.
Further, in the embodiment of the present invention, after the network access device establishes the first long connection with the cloud server based on the first preset communication protocol, the network access device further needs to compile a heartbeat message (i.e., a first heartbeat message) based on the first preset communication protocol according to a preset time interval (i.e., a first preset time interval), and send the first heartbeat message to the cloud server through the first long connection; after receiving a first heartbeat message sent by the network access device through the first long connection, the cloud server needs to compile a heartbeat message (i.e., a second heartbeat message) based on a first preset communication protocol, and send the second heartbeat message to the network access device through the first long connection, so as to maintain the first long connection.
203. After receiving the wake-up message sent by the cloud server through the first long connection, the network access device sends a wake-up confirmation message to the cloud server through the first long connection, and disconnects the first long connection.
And the awakening confirmation message is compiled by the network access equipment based on the first preset communication protocol.
In the embodiment of the invention, when the cloud server needs to issue the vehicle control instruction to the system chip, the cloud server compiles the wake-up message based on the first preset communication protocol and sends the wake-up message to the network access equipment through the first long connection with the network access equipment; after receiving the wake-up message sent by the cloud server through the first long connection, the network access device writes a wake-up confirmation message based on the first preset communication protocol, and sends the wake-up confirmation message to the cloud server through the first long connection so as to inform the cloud server that the system chip is about to be woken up, and disconnects the first long connection with the cloud server.
Further, in the embodiment of the present invention, when the wake-up message sent by the cloud server to the network access device includes the wake-up request identification code, and when the network access device compiles the wake-up confirmation message based on the first preset communication protocol, the cloud server needs to add the wake-up request identification code to the variable header of the wake-up confirmation message, so that the cloud server determines that the wake-up confirmation message fed back by the network access device corresponds to the wake-up message sent by the cloud server.
204. The network access device wakes up the system chip.
In the embodiment of the invention, the network access device sends the awakening confirmation message to the cloud server through the first long connection, and can awaken the system chip after the first long connection with the cloud server is disconnected, so that the system chip enters the awakening state from the dormant state.
205. The system chip establishes a second long connection with the cloud server based on a second preset communication protocol so that the cloud server sends the vehicle control command to the system chip through the second long connection.
In step 205, a second long connection is established between the system chip and the cloud server based on a second preset communication protocol, so that the cloud server issues the vehicle control command to the system chip through the second long connection, which may refer to the description of the corresponding part in fig. 1, and details of the embodiment of the present invention will not be repeated here.
Further, in the embodiment of the present invention, after the cloud server issues the vehicle control command to the system chip through the second long connection, the system chip may directly disconnect the second long connection; the second long connection can also be maintained to prevent the cloud server from issuing the vehicle control instruction to the system chip again in a short time. Specifically, the system chip and the cloud server may maintain the second long connection in the following manner: the system chip writes heartbeat messages (namely third heartbeat messages) based on a second preset communication protocol according to a preset time interval (namely a second preset time interval), and sends the third heartbeat messages to the cloud server through a second long connection; after receiving the third heartbeat message sent by the system chip through the second long connection, the cloud server needs to compile a heartbeat message (i.e., a fourth heartbeat message) based on a second preset communication protocol, and send the fourth heartbeat message to the system chip through the second long connection, so as to maintain the second long connection.
Further, in the embodiment of the present invention, when the system chip is in the wake-up state and there is data to be uploaded, the system chip needs to establish a long connection (i.e., a second long connection) with the cloud server based on the second preset communication protocol, and upload the data to be uploaded to the cloud server through the second long connection. Specifically, in this step, the system chip may establish a second long connection with the cloud server through a preset program, where the preset program is specifically an IOT-Service program, but is not limited thereto.
