Based on the characteristics of short vehicle starting time and long in-situ waiting time when the conventional underground coal mine rubber-tyred vehicle is used, a vehicle-mounted terminal with quick starting and long waiting time needs to be provided; however, the existing vehicle-mounted terminal has short standby time after the vehicle is flameout, and has about 30S of starting time when restarting; when the vehicle-mounted terminal is applied to a rubber-tyred car, the requirement of waiting for scheduling in a time on the rubber-tyred car cannot be met, and potential safety hazards are also caused. Aiming at the problems, the invention provides a switching method and a switching system for the power-saving working mode of the mining intrinsic safety type vehicle-mounted terminal.

Step S106, detecting that the power supply mode of the intrinsic safety power supply module is battery power supply, controlling to disconnect the power supply of the camera module, and entering a power saving mode.

As an optional embodiment, in the power saving mode, the camera is powered off, and the switching method further includes a process that the MCU controls the camera through the intrinsic safety power supply module to realize automatic power restoration, where the process includes the following steps:
Step S202, receiving a second ignition signal, and controlling the intrinsic safety power supply module to switch from battery power supply to external power supply;
And step S204, detecting that the power supply mode of the intrinsic safety power supply module is external power supply, controlling and recovering to supply power to the camera module, and entering a normal working mode.
In order to further improve the standby time of the vehicle-mounted terminal, the method is suitable for scheduling and using the underground coal mine rubber-tyred vehicle, and when the vehicle-mounted terminal is not needed to be used after the vehicle is flameout, the MCU processing unit can control the vehicle-mounted terminal to be switched from the power-saving mode to the low-power-consumption mode. As an alternative embodiment, the vehicle-mounted terminal may be controlled to switch from the power saving mode to the low power consumption mode by a manual operation, and the manual operation flow includes the following steps:
step S108, receiving a control signal and displaying a working mode selection popup window;
Step S110, a low power consumption mode determining command is received;
And step S112, a sleep command is sent to the android module so that the mining intrinsic safety type vehicle-mounted terminal enters a low-power consumption mode from a power saving mode.
The control command may be to set a low power button on the vehicle terminal by pressing the power key for a long time or explicitly, and send an operation command for entering the low power mode by pressing the low power button for a long time. For example, a long press of the on-off key 10S on the display screen of the in-vehicle terminal determines to enter the low power consumption mode.
As an optional implementation manner, the switching method can automatically enter a low-power consumption mode by detecting the battery power in the intrinsic safety power supply module, and the control flow is as follows:
And step S302, detecting that the residual battery capacity of the intrinsic safety power supply module is not more than 20% of the maximum battery capacity, and controlling the intrinsic safety type vehicle-mounted terminal to enter a low-power consumption mode. The step does not need to be directly entered manually, the power consumption of the low-power mode is about 100mA, and in the state, the vehicle-mounted terminal can stand by for about 10 days, and the vehicle-mounted terminal can be kept in contact with a ground dispatching center when the vehicle-mounted terminal is applied to a rubber-tyred car in a mine, so that the vehicle dispatching is facilitated.
When the vehicle enters a low power consumption mode, the vehicle ignites again, the vehicle terminal is connected to the external electricity, and the wake-up can be realized through the control of the MCU processing unit, and the specific wake-up steps are as follows:
step S114, receiving a third ignition signal, controlling the intrinsic safety power supply module to switch from battery power supply to external power supply, and recovering power supply to the camera module;
And step S116, sending a wake-up command to the android module so as to switch the mining intrinsic safety type vehicle-mounted terminal from a low-power consumption mode to a normal working mode.
