Method and system for switching power-saving working modes of mining intrinsic safety type vehicle-mounted terminal

Abstract

The invention provides a method and a system for switching power-saving working modes of a mining intrinsic safety type vehicle-mounted terminal, and relates to the field of vehicle-mounted terminals. The method is applied to an MCU processing unit of the mining intrinsic safety type vehicle-mounted terminal and comprises the steps that a first ignition signal is received, external power supply is connected, and all functional modules of the mining intrinsic safety type vehicle-mounted terminal are started; wherein the function module comprises an intrinsic safety power supply module, and the intrinsic safety power supply module comprises an external power supply and a battery power supply; receiving the flameout signal, and controlling the intrinsic safety power supply module to be switched to battery power supply; when battery power supply is detected, power supply of the camera module is cut off, and a power-saving mode is entered; when it is detected that the battery remaining capacity of the intrinsic safety power supply module does not exceed 20%, a low-power-consumption mode is controlled; or, receiving the control signal, and jumping out of the low-power-consumption mode to select the pop-up window; and selecting and sending a sleep command to the Android module, and controlling to enter a low-power-consumption mode. According to the method, the problems that an existing vehicle-mounted terminal is slow in starting and short in standby time are solved by switching the power-saving working mode of the vehicle-mounted terminal.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted terminals, in particular to a method and system for switching the power-saving working mode of a mine-used intrinsically safe vehicle-mounted terminal. Background technique [0002] Based on the special application scenario of coal mining, the existing rubber-wheeled vehicles used in coal mines have the characteristics of short start-up time and long in-situ waiting time when working underground. However, the current vehicle-mounted terminals on the market are characterized by After the vehicle is turned off, the standby time is short. Once the vehicle is turned off, the ground dispatch center and other drivers will not be able to get in touch with the driver of the vehicle, resulting in the situation that the vehicle cannot be dispatched and some vehicles are idle. In addition, after the vehicle is ignited, the on-board terminal starts slowly, usually taking 30S. At this time, the driver ...

Problems solved by technology

[0002] Based on the special application scenario of coal mining, the existing rubber-tyred vehicles used in underground coal mines have the characteristics of short vehicle start-up time and long waiting time in situ; however, the vehicle-mounted terminals currently on the market are characterized by The standby time of the vehicle is short after the engine is turned off. Once the vehicle is turned off, the ground dispatch center and other drivers will not be able to get in touch with the driver of the vehicle, resulting in the situation that the vehicle cannot be dispatched using vehicle dispatch, and some vehicles are idle.

In addition, after the vehicle is ignited, the vehicle-mounted terminal starts slowly, usually taking 30 seconds. At this time, the driver cannot observe the situation inside and outside the vehicle through the video monitoring of the vehicle-mounted terminal, and cannot communicate with the ground dispatching center.

The problem of slow startup and short standby time of the vehicle-mounted terminal is an important issue that plagues the safety of rubber-tyred vehicles driving underground
