The specific embodiment of the vehicle-mounted terminal of the present invention is substantially the same as the following embodiments of the vehicle monitoring method, and is not described herein again.
Referring to fig. 2, a first embodiment of the present invention provides a vehicle monitoring method including:
step S10, detecting whether the vehicle is in a sleep state;
in this embodiment, a vehicle-mounted terminal is installed in a vehicle, the vehicle-mounted remote terminal device is provided with a microcontroller MCU module and a 4G communication module (MPU for short, the same below), the MCU is used for connecting and collecting the CAN network data of the entire vehicle, and the MPU is used for receiving and analyzing the CAN data collected by the MCU and uploading the data to a remote service platform through network communication, so that the vehicle-mounted terminal CAN monitor the vehicle in real time; specifically, in this embodiment, whether real-time CAN data exist in the CAN bus network inside the vehicle is detected, and if it is detected that no real-time CAN data exist in the CAN bus network inside the vehicle, the controller inside the vehicle is in a closed state and no control information is sent, that is, the vehicle enters a sleep state; otherwise, the CAN bus network in the vehicle CAN be detected to have real-time CAN data, and the running of the CAN data shows that the vehicle does not enter the dormant state to run. The operation of the vehicle is required to be cooperatively regulated by a controller in the vehicle, the operation is mainly realized through CAN message data issued on a CAN bus, when the controller in the vehicle stops operating and enters a closing state, the controller to be closed sends corresponding CAN message information to prompt the controller to enter the closing state at present, and then the internal state of the vehicle CAN be determined through the CAN message information of the vehicle in the vehicle.
Step S20, if the vehicle is in a dormant state, controlling a timing module in the vehicle-mounted terminal to start timing;
step S30, if it is detected that the timing time in the timing module reaches a first preset time, the vehicle is waken up.
In this embodiment, according to the detection result in step S10, if the obtained result is that the vehicle is in a sleeping state, then the timing module inside the vehicle-mounted terminal is started and starts timing, the timing module may be started after the vehicle enters the sleeping state, and the control is not required through the CAN data, so that a large amount of power consumption is not consumed, meanwhile, the timing module further has a timing function, and may set a target time, the time setting may be a standard timing time set by the vehicle-mounted terminal when leaving the factory, for example, the general set timing time is set between 4 hours and 8 hours, and if the set time is too short, the vehicle will be frequently started, and the interior of the vehicle will frequently perform a sleep-wake-up operation, which may cause a certain loss to the vehicle. Therefore, the vehicle is awakened when the sleeping time recorded in the timing module reaches the set first preset time so as to prevent the vehicle from being in a low power consumption state for a long time and influencing the normal use of the controller in the vehicle, and therefore the vehicle needs to be awakened regularly in the sleeping state.
The implementation provides a vehicle monitoring method, which detects whether a vehicle is in a dormant state in real time; if the vehicle is in a dormant state, a timing module in the vehicle-mounted terminal is started, the dormant state is timed, when the timing time in the timing module reaches a first preset time, the standing vehicle is awakened, a regular awakening strategy can periodically acquire parameter information required by normal operation of the vehicle, and effective data support is provided for subsequent smooth operation of the vehicle.
Further, step S30 specifically includes:
step S31, waking up a microcontroller MCU module in the vehicle-mounted terminal;
and step S32, the MCU module is controlled to wake up the controller area CAN network node of the vehicle and send CAN message data.
In this embodiment, when it is detected that the sleep timing time recorded by the timing module inside the vehicle-mounted terminal reaches the first preset time, the timing module wakes up the microcontroller MCU module inside the vehicle-mounted terminal by generating corresponding data, and the woken-up MCU module sends the CAN message data to the CAN bus network, so as to wake up the CAN network, and the CAN network node resumes sending the CAN message data.
Further, after step S31, the method further includes:
step S33, controlling the MCU module to wake up a microprocessor MPU module in the vehicle-mounted terminal, wherein the MPU module is used for receiving and analyzing CAN data collected by the MCU;
and step S34, controlling to upload the analyzed CAN data to a remote service platform.
In this embodiment, after waking up the MCU module in step S31, the MCU module also wakes up the CAN network and wakes up the microprocessor MPU module, and the MPU module is configured to receive and analyze the CAN data collected by the MCU, so as to realize that the MPU module uploads the CAN data to the remote service platform through network communication, thereby realizing monitoring of the vehicle state.
Further, after step S32, the method further includes:
step S35, recording the duration of CAN message data transmission;
and step S36, if the duration time is detected to reach a second preset time, controlling the CAN network to sleep.
In the embodiment, after the vehicle is awakened, the timing module of the vehicle-mounted terminal records the awakening time of the vehicle, namely, by detecting the duration of CAN message data transmission in the CAN network and when the duration reaches the second preset time, then the CAN network dormancy control instruction is started to control the CAN network to enter the dormancy state, the second preset time may also be preset and may vary somewhat depending on the vehicle model or brand, e.g., generally, the duration of the second preset time CAN be set to be less than two minutes, the CAN data of the whole vehicle CAN be acquired, the electric quantity of a 12V battery of the vehicle CAN not be greatly lost, and when the vehicle is awakened regularly, if the electric quantity of the 12V battery of the whole vehicle is lower, the standby battery of the vehicle-mounted terminal can be switched to supply power so as to realize the awakening and sleeping of the vehicle. Therefore, in the embodiment, the second preset time is set for awakening the vehicle during operation, so that the condition that the CAN data of the whole vehicle is acquired and too large loss of the vehicle is not caused CAN be met, and the purpose of remotely monitoring the vehicle is achieved.
Further, step S36 includes:
step S37, controlling the MCU module to sleep;
in step S38, the control MPU module initializes reset.
In step S39, the MPU module is controlled to enter the sleep mode and starts a timer module inside the in-vehicle terminal.
In this embodiment, after the vehicle CAN network operates for the second preset time, the MCU module of the vehicle-mounted terminal is started in advance to sleep, so that the vehicle CAN network enters a sleep state, and the vehicle enters a low power consumption mode. After the MCU module and the CAN network are dormant, the MPU module does not need to perform data processing, and then after a certain time, the MPU module is controlled to start initialization reset so as to ensure that the system is in an optimal state. Meanwhile, when the vehicle is detected to be in a dormant state, a timing module in the vehicle-mounted terminal starts a new dormant timing.

The timing module 20 is used for controlling a timing module in the vehicle-mounted terminal to start timing if the vehicle is in a dormant state;
and the awakening module 30 is configured to awaken the vehicle if it is detected that the timing time in the timing module reaches a first preset time.

Therefore, the vehicle is awakened when the sleeping time recorded in the timing module reaches the set first preset time so as to prevent the vehicle from being in a low power consumption state for a long time and influencing the normal use of the controller in the vehicle, and therefore the vehicle needs to be awakened regularly in the sleeping state.
