Based on the characteristics of short vehicle starting time and long in-situ waiting time when the existing underground coal mine rubber-tyred vehicle is used, a vehicle-mounted terminal with quick starting and long standby time needs to be equipped; however, the conventional in-vehicle terminal has a short standby time after the vehicle is turned off, and has a start time of about 30S when restarting; when the vehicle-mounted terminal is applied to the rubber-tyred vehicle, the requirement of waiting for scheduling on the rubber-tyred vehicle in a ready mode cannot be met, and potential safety hazards are also caused. The invention provides a switching method and a system for the power-saving working mode of a mining intrinsic safety type vehicle-mounted terminal, aiming at the problems.
The invention discloses a method for switching power-saving working modes of a mining intrinsic safety type vehicle-mounted terminal, which is applied to an MCU processing unit arranged in the mining intrinsic safety type vehicle-mounted terminal and comprises the following steps:
step S102, receiving a first ignition signal, connecting an external power supply, and starting all functional modules of the mining intrinsic safety type vehicle-mounted terminal; the mining intrinsic safety type vehicle-mounted terminal comprises a functional module, an intrinsic safety power supply module, an android module, a camera module, a voice module and a display module, wherein the functional module supplies power to an MCU processing unit, the android module, the camera module, the voice module and the display module are controlled by the MCU processing unit, and the intrinsic safety power supply module comprises external power supply and battery power supply;
step S104, receiving a flameout signal, and controlling the intrinsic safety power supply module to be switched from external power supply to battery power supply;
and S106, detecting that the power supply mode of the intrinsic safety power supply module supplies power to the battery, controlling to cut off the power supply of the camera module, and entering a power saving mode.
The steps S102-S106 realize the process that the vehicle-mounted terminal enters the power saving mode from the normal working mode, and essentially adopts the process that the MCU processing unit controls the camera module to automatically power off; the first ignition signal is generally vehicle ignition, and the vehicle-mounted terminal is powered by a whole vehicle power system; when the vehicle is flamed out, this ampere of power module switches the battery power supply, if the vehicle that corresponds keeps letting on the normal work of vehicle terminal system, the battery electric quantity can only support and make a video recording and speech communication in the short time, consequently, through cutting off the power supply to the module of making a video recording to guarantee this ampere of power module's battery electric quantity can support vehicle terminal to carry out long-time speech communication, can avoid the phenomenon of the unable dispatch that takes place communication interruption and lead to when being applied to colliery rubber-tyred car in the pit.
As an optional embodiment, in the power saving mode, the camera has no power, and the switching method further includes a process in which the MCU processing unit controls the camera to automatically reset the power supply through the intrinsically safe power supply module, where the process includes the following steps:
step S202, receiving a second ignition signal, and controlling the intrinsic safety power supply module to be switched from battery power supply to external power supply;
and S204, detecting that the power supply mode of the intrinsic safety power supply module is external power supply, controlling to recover power supply 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 of the underground coal mine rubber-tyred vehicle, and after the vehicle is flamed out, when the vehicle-mounted terminal is not needed to be used, the method can control the vehicle-mounted terminal to be switched from the power-saving mode to the low-power-consumption mode through the MCU processing unit. As an optional implementation manner, the vehicle-mounted terminal may be controlled to switch from the power saving mode to the low power consumption mode through a manual operation, and the manual operation process includes the following steps:
step S108, receiving a control signal and displaying a working mode selection popup;
step S110, receiving a low power consumption mode determining command;
and step S112, sending a sleep command to the android module so that the mining intrinsic safety type vehicle-mounted terminal can enter a low power consumption mode from a power saving mode.
The control command can be an operation command for entering a low power consumption mode by long-pressing the power-off key or explicitly setting a low power consumption button on the vehicle-mounted terminal. For example, a long press of the on/off key 10S on the display screen of the in-vehicle terminal determines that the low power consumption mode is entered.
As an optional implementation manner, the switching method may automatically enter the low power consumption mode by detecting the battery power in the intrinsically safe power supply module, and the control flow is as follows:
step S302, detecting that the residual electric quantity of the battery of the intrinsic safety power supply module does not exceed 20% of the maximum capacity of the battery, controlling to enter a low power consumption mode, and enabling the mining intrinsic safety type vehicle-mounted terminal to be dormant. The step does not need to be directly entered manually, the power consumption of the low power consumption mode is about 100mA, the vehicle-mounted terminal can be in standby for about 10 days in the state, and the vehicle-mounted terminal can keep contact with a ground dispatching center when being applied to rubber-tyred vehicles in mines, so that the vehicle dispatching is facilitated.
After the vehicle enters the low power consumption mode, the vehicle is ignited again, the vehicle terminal is connected with external power, and the vehicle terminal can be awakened through the control of the MCU processing unit, specifically, the awakening step is as follows:
step S114, receiving a third ignition signal, controlling the intrinsic safety power supply module to be switched from battery power supply to external power supply, and recovering power supply to the camera module;
and S116, sending a wake-up command to the android module so that the mining intrinsic safety type vehicle-mounted terminal can be switched to a normal working mode from a low power consumption mode.
