step S11, detecting whether the load voltage of the vehicle is smaller than a first preset voltage;
step S12, if the load voltage of the vehicle is detected to be smaller than the first preset voltage, switching to a standby battery of the vehicle-mounted terminal for power supply.
In the embodiment, a vehicle-mounted terminal is installed in a vehicle, the vehicle-mounted terminal is connected with other modules in the vehicle through a whole vehicle CAN network, so that the vehicle-mounted terminal CAN acquire CAN signals in the vehicle in real time to determine the running state of each part in the vehicle, a communication module in the vehicle-mounted terminal is connected with a remote service platform through the communication network, the communication module of the vehicle-mounted terminal CAN acquire data information in an internal memory of the vehicle-mounted terminal in real time, and the vehicle-mounted terminal CAN transmit the data information of the vehicle to the remote service platform for storage through the communication module in real time; the vehicle-mounted terminal is internally provided with a standby battery, the standby battery is used when the vehicle-mounted terminal fails in power supply of the vehicle main battery, the vehicle main battery and the vehicle-mounted terminal are connected through a connecting circuit to supply power for normal operation of the vehicle-mounted terminal, the vehicle main battery is used for supplying power for the power utilization terminal in the vehicle, the vehicle-mounted terminal is further provided with a detection circuit, the detection circuit is used for detecting a real-time load voltage value in the vehicle, the load voltage is a voltage value of a vehicle-mounted 12V battery in the vehicle, the real-time voltage value of the vehicle-mounted 12V battery is detected according to the vehicle-mounted terminal and compared with a preset first preset voltage value, and when the load voltage is smaller than the first preset voltage, the vehicle-mounted terminal switches internal power supply from the original vehicle main battery to the standby battery of the vehicle-mounted terminal to supply power, so that normal operation of the vehicle-mounted terminal is guaranteed.
The embodiment provides a power supply management method of a vehicle-mounted terminal, which is characterized in that whether the load voltage of a vehicle is smaller than a first preset voltage or not is detected, and when the load voltage of the vehicle is smaller than the first preset voltage, power supply inside the vehicle-mounted terminal is required to be switched to a standby battery in real time to supply power, so that the influence of sudden power failure of the vehicle on the vehicle is avoided, the discharging switching logic of the standby battery is simplified, and the subsequent effective uploading of vehicle data is guaranteed.
Further, after step S12, the method further includes:
step S21, recording the working operation time of the standby battery;
and S22, if the running time of the standby battery reaches the first preset time, controlling the vehicle-mounted terminal to sleep.
In this embodiment, after the power supply in the vehicle terminal is switched to the standby battery of the vehicle terminal, the timing module in the vehicle terminal records the working operation time of the standby battery in real time, and presets the first preset time for the independent working of the standby battery, where the first preset time refers to the optimal time set by the standby battery for the power supply operation of the vehicle terminal, the service life of the vehicle terminal battery is reduced if the operation time is too long, and the too short operation time cannot provide effective data support for the subsequent normal operation of the vehicle, and in general, the set first preset time is 10 minutes, and after the working operation time of the standby battery in the vehicle reaches the first preset time, the sleep module in the vehicle terminal is started to enable the vehicle terminal to enter a sleep state, where the sleep mode is to sleep according to the normal CAN network logic, and the timing sleep setting of the vehicle terminal not only ensures the service life of the standby battery, but also reduces the energy consumption of the vehicle.

In this embodiment, in the process that the running time of the standby battery in the vehicle-mounted terminal does not reach the set first preset time, the vehicle terminal determines whether the vehicle-mounted terminal receives the CAN data transmitted in the vehicle through the internal detection module, and generally, when the power supply battery in the vehicle-mounted terminal changes, if the vehicle has real-time data to upload to the vehicle terminal, the vehicle-mounted terminal still receives the CAN data in the vehicle, so that other modules of the vehicle stored in the vehicle-mounted terminal transmit related CAN data information to the vehicle-mounted terminal through the CAN network, and at the moment, the vehicle-mounted terminal uploads the received data to the remote service platform for storage in real time, so that the timely transmission and storage of the real-time data information in the vehicle is realized, effective data support is provided for normal operation of the vehicle in the future, and the subsequent normal use of the vehicle is ensured.

In this embodiment, based on the detection result in step S31, whether real-time CAN data is received in the vehicle-mounted terminal, if the real-time CAN data is not received in the vehicle-mounted terminal, then it is further checked whether there is any data that is not timely transmitted to the remote service terminal in the communication module of the vehicle-mounted terminal, if it is detected that CAN data to be uploaded is stored in the communication module of the vehicle-mounted terminal, in the standby battery power supply state of the vehicle-mounted terminal, at this time, the data in the communication module of the vehicle-mounted terminal is also uploaded to the remote service platform according to the frequency stored by the previous data or the set frequency; for example, if the data storage frequency in the communication module of the vehicle-mounted terminal is 2 seconds, the data is uploaded to the remote service platform in the communication module of the vehicle-mounted terminal according to the frequency of 2 seconds. In this embodiment, when it is detected that the data information which is not timely sent to the remote service platform is stored in the communication module of the vehicle-mounted terminal, each component inside the vehicle-mounted terminal cannot affect the normal operation of each component due to the change of the power supply battery, that is, the data information of the vehicle is timely uploaded to the remote service platform, and effective data support is provided for the subsequent analysis of the vehicle.
Further, after step S22, the method further includes:
s51, waking up the vehicle-mounted terminal;
in this embodiment, after the vehicle-mounted terminal enters the sleep mode, the vehicle-mounted terminal is subsequently awakened according to actual needs. The method comprises the steps that when a vehicle-mounted terminal starts to sleep, a sleep timing module is started, the timing module is used for recording the duration of the vehicle-mounted terminal in a sleep mode, after the duration of the sleep mode of the vehicle-mounted terminal reaches a preset set time, the timing module wakes a micro controller MCU module in the vehicle-mounted terminal, the waken MCU module generates CAN message data and sends the CAN message data to a CAN bus network, and then the CAN network is waken, so that CAN network nodes resume sending the CAN message data, and the purpose of waking the vehicle-mounted terminal is achieved; besides, the wake-up vehicle-mounted terminal can also control the vehicle-mounted terminal to be converted into the working mode from the sleep mode according to the wake-up instruction sent by the external controller besides the timed wake-up, and the external controller can be a vehicle key matched with the starting vehicle.
Step S52, detecting whether the load voltage of the vehicle is greater than a second preset voltage;
and step S53, if the load voltage of the vehicle is larger than the second preset voltage, the vehicle-mounted terminal is controlled to restart, and the vehicle-mounted terminal is switched to the main battery to supply power.
In this embodiment, after the vehicle-mounted terminal is awakened, according to the detection circuit of the vehicle-mounted terminal, the voltage value of the real-time load voltage in the vehicle is detected, and according to the second preset voltage in the vehicle, the detected load voltage is compared with the second preset voltage, if the load voltage of the vehicle is greater than the second preset voltage, the power supply battery in the vehicle-mounted terminal is switched to the main battery for supplying power to the vehicle, that is, the vehicle is 12V battery for supplying power, and when the power supply in the vehicle-mounted terminal is switched to the main battery for supplying power, the system is restarted in the vehicle-mounted terminal at this time, so as to ensure that the terminal equipment resumes normal operation, and further improve the robustness of the vehicle-mounted terminal, wherein the second preset voltage is greater than the first preset voltage.
In step S54, if the load voltage of the vehicle is less than or equal to the second preset voltage, the standby battery of the vehicle-mounted terminal is continuously supplied.
In this embodiment, if the detected load voltage of the vehicle is less than or equal to the second preset voltage, the main battery of the vehicle cannot be used to supply power to the vehicle in the vehicle-mounted terminal, so that the standby battery still continues to be selected to supply power to the vehicle-mounted terminal.
In addition, the embodiment of the invention also provides a computer storage medium, wherein the computer storage medium is stored with a battery management program of the vehicle-mounted terminal, and the battery management program of the vehicle-mounted terminal realizes the steps of the battery management method of the vehicle-mounted terminal when being executed by a processor.
