Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The following describes a wake-up system of a vehicle-mounted terminal, a vehicle, a server, and a wake-up method of a vehicle-mounted terminal according to embodiments of the present invention with reference to the accompanying drawings.
Fig. 2 is a block diagram of a wake-up system of a vehicle-mounted terminal according to an embodiment of the present invention. As shown in fig. 2, the wake-up system of the vehicle-mounted terminal according to the embodiment of the present invention includes: control terminal 100, server 200, and in-vehicle terminal 300. The control terminal 100 and the server 200 perform wireless communication, and the server 200 and the in-vehicle terminal 300 perform wireless communication.
The control terminal 100 is configured to receive a control instruction of a user and send the control instruction to the server 200.
In one embodiment of the present invention, the control terminal 100 may be a mobile phone, a tablet computer, a PC, or the like.
Specifically, when the user needs to control the vehicle, the user sends a control instruction, for example, an instruction to control the on-board air conditioner, to the server 200 through the application program in the control terminal 100.
The server 200 transmits a control command to the in-vehicle terminal 300 to wake up the in-vehicle terminal 300 when determining that it is in a connected state with the in-vehicle terminal 300.
Specifically, the server 200 receives the control instruction transmitted by the control terminal 100, and transmits the control instruction to the in-vehicle terminal 300 to wake up the in-vehicle terminal 300 when it is determined that the in-vehicle terminal 300 is online in real time.
The vehicle-mounted terminal 300 is configured to periodically send a first network packet to the server 200 in the sleep state to maintain a communication connection with the server 200, and the vehicle-mounted terminal 300 is further configured to control the vehicle according to a control instruction after waking up.
Specifically, when the in-vehicle terminal 300 is in a sleep state (i.e., a low power consumption state), the in-vehicle terminal 300 maintains a communication connection with the server 200, that is, the in-vehicle terminal 300 is online in real time with respect to the server 200. The real-time online of the in-vehicle terminal 300 means that the in-vehicle terminal 300 sends the first network packet to the server 200 at regular time in a dormant state so as to maintain the communication connection with the server 200. The vehicle-mounted terminal 300 is on line in real time in the dormant state, so that the response speed of the vehicle-mounted terminal 300 to the control instruction of the user is improved.
It should be noted that, the in-vehicle terminal 300 sends a first network data packet (may be referred to as a low power consumption heartbeat packet) to the server 200 at regular time in the sleep state, and the in-vehicle terminal 300 sends a second network data packet (may be referred to as a normal heartbeat packet) to the server 200 at regular time in the normal operation state to maintain the connection of the communication link, where the first network data packet and the second network data packet are different, for example, the format and the data content of the network data packet are different, so that the server 200 distinguishes the normal heartbeat packet and the low power consumption heartbeat packet.
In addition, if the in-vehicle terminal 300 receives the control command transmitted from the server 200 in the sleep state, it wakes itself up and controls the corresponding components in the vehicle to execute the control command.
In an embodiment of the present invention, the server 200 is specifically configured to: when a control instruction sent by the control terminal 100 is received, whether a first network data packet sent by the vehicle-mounted terminal 300 is received within a preset time is judged, if yes, the vehicle-mounted terminal 300 is judged to be in a connected state, and if not, the vehicle-mounted terminal 300 is judged to be in a non-connected state.
In one embodiment of the present invention, the server 200 is further configured to generate a prompt message when determining that the vehicle-mounted terminal 300 is in a non-connected state, and transmit the prompt message to the control terminal 100 to be provided to the user.
Specifically, after the server 200 receives the control instruction sent by the control terminal 100, the server 200 determines whether the in-vehicle terminal 300 is online according to the recent (i.e., within the preset time) reception condition of the low-power-consumption heartbeat packet. For example, if the server 200 normally receives a low-power heartbeat packet in the near term (for example, within 100 seconds before and after the server 200 receives the control instruction), it is determined that the in-vehicle terminal 300 is online in real time, and then the control instruction is sent to the in-vehicle terminal 300, so that the in-vehicle terminal 300 executes the control instruction of the user; if the server 200 does not receive the low-power-consumption heartbeat packet recently, it is determined that the vehicle-mounted terminal 300 is not online, that is, the server 200 and the vehicle-mounted terminal 300 are disconnected from each other in a communication manner, then the server 200 directly notifies the user that the vehicle-mounted terminal 300 is not online, and the vehicle cannot be controlled.
In one embodiment of the present invention, as shown in fig. 3, the in-vehicle terminal 300 includes: a control chip 310 and a wireless communication module 320.
In one embodiment of the present invention, the wireless communication module 320 is a 2G/3G/4G wireless communication module.
When the vehicle-mounted terminal 300 is in the sleep state, the wireless communication module 320 periodically enters the wake-up mode to send the first network packet to the server 200, and sends a wake-up signal to the control chip 310 to wake up the control chip 310 when receiving a control instruction; the control chip 310 wakes up the wireless communication module 320 after waking up; the wireless communication module 320 sends the control instruction to the control chip 310 after waking up; the control chip 310 controls the vehicle according to the control command.
Specifically, before the in-vehicle terminal 300 enters the sleep state, the in-vehicle terminal 300 is networked to the server 200, and performs tasks such as network communication after the authentication is successful. When an engine of a vehicle is turned off, the entire vehicle needs to enter a low power consumption state, then, when the vehicle-mounted terminal 300 obtains a vehicle flameout notification from a vehicle CAN bus (controller area network field bus), the control chip 310 controls the wireless communication module 320 to enter a sleep state, and turns off power supplies of other components, the control chip 310 enters a power-down mode, the vehicle-mounted terminal 300 enters a low power consumption state, namely the sleep state, and the current of the vehicle-mounted terminal 300 in the sleep state is small, for example, the current does not exceed 5 mA.
More specifically, when the in-vehicle terminal 300 enters the sleep state, the wireless communication module 320 wakes up periodically to transmit the low power consumption heartbeat packet to the server 200, and at this time, the control chip 310 and other components of the in-vehicle terminal 300 are still in the sleep state, so that power consumption is reduced, and the wireless communication module 320 continues to enter the sleep state after transmitting the low power consumption heartbeat packet each time. Because the task of sending the low-power-consumption heartbeat packet is relatively simple and the power consumption is not high, the time from the time of awakening to send the data to the time of entering the dormant state again is short, the functional requirements of real-time online and data awakening of the vehicle-mounted terminal 300 can be met, and the performance requirement of low power consumption can also be met.
Further, when the vehicle-mounted terminal 300 is in the sleep state, if the wireless communication module 320 receives a control instruction issued by the server 200, the wireless communication module 320 generates a pulse to wake up the control chip 310 as an external interrupt, after the control chip 310 enters the normal operating state from the sleep state, the control chip 310 sequentially wakes up the wireless communication module 320 and turns on the power supplies of other components, after the wireless communication module 320 wakes up, the control instruction is sent to the control chip 310, after the control chip 310 receives the control instruction, the control chip 310 starts to process the control instruction of the user to control the vehicle to execute a corresponding operation (for example, turn on the vehicle-mounted air conditioner), after the vehicle-mounted terminal 300 controls the vehicle to execute the control instruction, the execution result is uploaded to the server 200 through the wireless communication module 320, and the server 200 issues the execution result to the control terminal 100 of the user, the control terminal 100 provides the execution result to the user, for example, informing the user that the in-vehicle air conditioner is turned on.
The in-vehicle terminal will be further described with reference to fig. 3 and 4.
Specifically, as shown in fig. 3, the wireless communication module 320 is physically connected to the control chip 310 through a serial port, a USB interface, or another communication interface, and the control chip 310 communicates with the wireless communication module 320 through the interface to implement the sending and receiving functions; the low-power sleep management pin and the sleep wake-up pin of the wireless communication module 320 are connected to a GPIO (General Purpose Input Output) port (not shown) of the control chip 310, the control chip 310 controls the time and the scene when the wireless communication module 320 enters the low power consumption, and the wireless communication module 320 generates a pulse at the sleep wake-up pin after receiving the network data to wake up the control chip 310 of the vehicle-mounted terminal 300; in addition, the power control and power on/off pins of the wireless communication module 320 are controlled by the control chip 310 of the in-vehicle terminal 300.
In one embodiment of the present invention, the wireless communication module 320 provides a call interface instruction to support the control chip 310 to set, query, and execute the related functions through the instruction. For example, setting the state of the wireless communication module 320, such as a low power consumption state, and automatically returning a result code after a network is disconnected; basic information of the wireless communication module 320, such as model and registration state, is inquired; and executing the tasks of returning signal strength and the like.
In addition, the wireless communication module 320 also supports automatic network packet transmission, and parameters such as a transmission IP address, a port, data content, and a transmission period are configurable.
In one embodiment of the present invention, the function of the wireless communication module 320 to send the first network packet in the dormant state at regular time is preset. For example, the setting is performed before the in-vehicle terminal 300 is shipped from the factory. Specifically, the in-vehicle terminal 300 sets parameters of the wireless communication module 320 for periodically transmitting the network data packet after entering low power consumption through the interface instruction provided by the wireless communication module 320, for example, the parameters are set as: IP address, port, format and content of network data packet, data channel, period of timing transmission, etc. For example, the transmission format and the transmission content of the first network packet are as follows: "send 16 bytes of 0xAA data to 128.0.17.51IP address, 5001 port in UDP transport with sending cycle 90 s".
As shown in fig. 4, the in-vehicle terminal 300 includes a wireless communication module 320, a control chip 310, and other components and peripheral circuits 330 connected to the control chip 310.
In some embodiments of the present invention, the wireless communication module 320 may be a GSM/2G, GPRS/2.5G, CDMA/3G or LTE/4G wireless module.
In one embodiment of the present invention, the wireless communication module 320 may employ a WCDMA/3G module, such as a 3G extrapolation SIM card.
The wireless communication module 320 provides a set of AT (Attention) command set, and the control chip 310 or the PC of the in-vehicle terminal 300 can call AT commands (a modem command language) to perform communication interaction with the wireless communication module 320.
In one embodiment of the present invention, the control chip 310 may be selected from a highly integrated microcontroller with excellent low power performance.
As shown in fig. 4, a UART (Universal Asynchronous Receiver/Transmitter) interface of the control chip 310 is connected to a standard 8-wire serial port UART of the wireless communication module 320, and the control chip 310 sends an AT command through the UART interface, interrupts and receives a result code returned by the wireless communication module 320, and network data sent by the server 200. The WAKEUP _ IN is a low power consumption sleep management pin of the wireless communication module 320, and the control chip 310 pulls down the pin to notify the wireless communication module 320 to enter a sleep state, and the control chip 310 pulls up the pin to wake up the wireless communication module 320 from the low power consumption state; the WAKEUP _ OUT is a UART _ RI pin of the wireless communication module 320, and generates a pulse when the wireless communication module 320 receives a control instruction sent by the server 200, the WAKEUP _ OUT is connected to a GPIO port of the control chip 310, and when the control instruction arrives, the pulse output by the UART _ RI pin of the wireless communication module 320 is used as an external interrupt to wake up the control chip 310, thereby implementing a function of waking up the vehicle-mounted terminal 300 by network data; POWER refers to 3 pins (not shown in fig. 4) for POWER control and POWER on/off of the wireless communication module 320, the control chip 310 controls the wireless communication module 320 to be powered on and powered off through the POWER control pin, and controls the wireless communication module 320 to be powered on and powered off through the POWER on/off pin, so that the control chip 310 performs POWER on/off or restart operations on different occasions.
In an embodiment of the present invention, the other components connected to the control chip 310 and the peripheral circuit 330 may include a GPS location information collecting module, a plug-in memory chip, a power supply system, and the like.
In some embodiments of the present invention, if the requirements for power consumption and the like are not high, real-time online of the vehicle-mounted terminal in the sleep state can be realized in the following manner. For example, when the vehicle-mounted terminal is in a sleep state, the control chip automatically wakes up at regular time, and simultaneously wakes up the wireless communication module to complete the task of sending the low-power-consumption heartbeat packet to the server, and then enters the sleep state.
The awakening system of the vehicle-mounted terminal of the embodiment of the invention has the advantages that the vehicle-mounted terminal sends a first network data packet to the server at regular time in a dormant state so as to keep communication connection with the server, when a user wants to control a vehicle, the user sends a control instruction to the server through the control terminal, the server sends the control instruction to the vehicle-mounted terminal when judging that the vehicle-mounted terminal is in a connection state so as to awaken the vehicle-mounted terminal, the vehicle-mounted terminal controls the vehicle according to the control instruction after awakening, the vehicle-mounted terminal keeps a real-time online state in the dormant state, and the vehicle-mounted terminal immediately awakens and executes the control instruction when receiving the control instruction, so that the real-time performance is greatly improved, the waiting time of the user for remotely controlling the vehicle is effectively reduced, and the system adopts wireless network data to awaken the vehicle-, the service cost of the vehicle-mounted terminal is reduced, and the user experience is further improved.

And S3, the vehicle-mounted terminal controls the vehicle according to the control instruction after waking up, wherein the vehicle-mounted terminal sends the first network data packet to the server at regular time when being in the dormant state so as to maintain the communication connection with the server.
In one embodiment of the invention, the vehicle-mounted terminal comprises a wireless communication module, and when the vehicle-mounted terminal is in a dormant state, the wireless communication module enters an awakening mode periodically to transmit the first network data packet to the server so as to maintain communication connection with the server.
Specifically, the vehicle-mounted terminal comprises a wireless communication module and a control chip. When an engine of a vehicle is flamed out, the whole vehicle needs to enter a low power consumption state, and then when the vehicle-mounted terminal acquires a vehicle flameout notification from a vehicle CAN bus, the control chip controls the wireless communication module to enter a dormant state, and turns off the power supply of other parts, the control chip enters a power-down mode, and the vehicle-mounted terminal enters a low power consumption state, namely the dormant state.
Further, after the vehicle-mounted terminal enters the sleep state, the wireless communication module wakes up regularly to send the low-power heartbeat packet to the server, and at the moment, the control chip and other components are still in the sleep state, so that the power consumption is reduced, and the wireless communication module continues to enter the sleep state after sending the low-power heartbeat packet each time. Because the task of sending the low-power-consumption heartbeat packet is relatively simple and the power consumption is not high, the time from the time of awakening to send the data to the time of entering the dormant state again is short, the functional requirements of real-time online and data awakening of the vehicle-mounted terminal can be met, and the performance requirement of low power consumption can also be met.

Specifically, after receiving a control instruction sent by the control terminal, the server determines whether the vehicle-mounted terminal is online according to the recent (i.e., within a preset time) reception condition of the low-power-consumption heartbeat packet. For example, if the server normally receives a low-power-consumption heartbeat packet recently (e.g., within 100 seconds before and after the server receives the control instruction), the vehicle-mounted terminal is determined to be online in real time, and the control instruction is sent to the vehicle-mounted terminal, so that the vehicle-mounted terminal executes the control instruction of the user; and if the server does not receive the low-power-consumption heartbeat packet recently, judging that the vehicle-mounted terminal is not on line, namely, the server and the vehicle-mounted terminal are disconnected in communication.
In one embodiment of the present invention, further comprising: and the server generates prompt information when judging that the server is in a non-connection state with the vehicle-mounted terminal, and sends the prompt information to the control terminal to be provided for the user.

Fig. 9 is a flowchart of a wake-up method of a vehicle-mounted terminal according to an embodiment of the invention. As shown in fig. 9, the wake-up method includes the following steps:
s101, the vehicle-mounted terminal performs initialization operations including initialization operations on a hardware driver, a clock, a communication module, a global variable and the like when the whole vehicle is started immediately before delivery, is powered on again or the control chip is restarted.
S102, after initialization is completed, the vehicle-mounted terminal is networked to a background server in a dialing APN mode, and then login, namely identity authentication, is carried out.
For example, the vehicle-mounted terminal opens 4 socket wireless connections and selects a UDP transmission protocol, wherein the number of the opened socket wireless connections is determined according to actual requirements, and the UDP protocol is selected because the embodiment of the invention is mainly used for transmitting a large amount of network data and has higher requirements on high speed, simple structure and small load.
S103, the vehicle-mounted terminal sets parameters of a low-power-consumption heartbeat packet sent by the communication module in a dormant state.
The selected wireless communication module can negotiate with a supplier, and after the version of the wireless communication module is updated, the wireless communication module can send the first network data packet according to the set parameter period in the dormant state. For example, the parameters are set as: parameters such as an IP address, a port, data content, a data channel, and a sending period are sent, for example, a socket2 link is selected to keep a socket2 link in a dormant state to be communicated with a server. For example, the transmission format and the transmission content are: "send 16 bytes of 0xAA data to 128.0.17.51IP address, 5001 port in UDP transport with sending cycle 90 s".
It should be noted that the parameter setting for sending the low-power heartbeat packet to the wireless communication module may be completed before the vehicle leaves the factory. After the vehicle leaves the factory, the wireless communication module has the function of sending the first network data packet at regular time in the dormant state.
And S104, the vehicle-mounted terminal executes various tasks in a normal working state.
For example, various network tasks are performed, such as collecting vehicle real-time information, vehicle terminal status information, collecting location information, collecting CAN data, forwarding data, exception handling, and the like.
And S105, judging whether the vehicle is flameout or not by the vehicle-mounted terminal according to the collected vehicle state CAN message. If the engine is not turned off, the process continues to step S104, and if it is determined that the engine is turned off, the in-vehicle terminal is ready to enter a low power consumption state, and then step S106 is performed.
And S106, the vehicle-mounted terminal enters a sleep state.
The work required to be completed in the step comprises uploading the states of the vehicle and the vehicle-mounted terminal to a server, storing relevant data and variables, turning off the power supplies of other parts, and pulling down the low-power consumption dormancy management pin of the wireless communication module by the control chip.
S107, in the sleep state, the vehicle-mounted terminal periodically sends a low-power-consumption heartbeat packet to the server.
For example, if the set transmission cycle is 1min, when the transmission cycle is 1min, the wireless communication module automatically wakes up, sends 16Byte 0xAA to the socket2IP address and the port in the UDP protocol to the server, and enters the sleep state after the sending is completed.
It should be noted that, if the vehicle-mounted terminal is not networked before entering the sleep state or the wireless communication module automatically wakes up to find that the network is disconnected, the wireless communication module automatically completes the networking action.
And S108, the wireless communication module of the vehicle-mounted terminal judges whether network data arrives or other interrupts occur. If yes, step S109 is executed, and if no, step S107 is continued.
The network data refers to data sent by a server through a wireless network.
And S109, waking up the control chip and other components of the vehicle-mounted terminal.
If the wireless communication module receives a control instruction (for example, an instruction for controlling the on-board air conditioner) sent by the server, the wireless communication module outputs a pulse at the UART _ RI pin to wake up the control chip, and transmits the received control instruction to the control chip through the UART interface.
After the control chip is awakened, the low-power-consumption dormancy management pin WAKEUP _ IN of the wireless communication module is pulled up to awaken the wireless communication module, and the control chip performs operations of initialization, power supply of other parts, network data uploading task recovery and the like. In addition, the wireless communication module sends the control instruction to the control chip after awakening.
And S110, the vehicle-mounted terminal executes the control command and returns the execution result to the server.
Specifically, a control chip of the vehicle-mounted terminal analyzes the control instruction, issues the analyzed control instruction to a CAN bus of the vehicle, and after a series of interactions with the CAN bus, the vehicle turns on the air conditioner or does not turn on the air conditioner, the vehicle-mounted terminal collects CAN messages of success or failure of opening or other results, uploads a result data packet for executing the turning on of the air conditioner to the server, and then issues the result data packet to a user client by the server, so that a user CAN know an execution result.
In the awakening method of the vehicle-mounted terminal of the embodiment of the invention, the vehicle-mounted terminal sends the first network data packet to the server at regular time in the dormant state so as to keep the communication connection with the server, when the user wants to control the vehicle, the control terminal receives the control instruction of the user and sends the control instruction to the vehicle-mounted terminal through the server, the vehicle-mounted terminal immediately wakes up when receiving the control instruction, and controls the vehicle according to the control instruction, the vehicle-mounted terminal keeps a real-time online state in a dormant state, when the vehicle-mounted terminal receives the control instruction, the vehicle-mounted terminal immediately wakes up and executes the control instruction, thereby greatly improving the real-time performance, effectively reducing the waiting time of the user for remotely controlling the vehicle, in addition, the method wakes up the vehicle-mounted terminal by adopting the wireless network data without a telephone/short message mode, reduces the service cost of the vehicle-mounted terminal and further improves the user experience.
