Method for controlling low power consumption of industrial vehicle-mounted display screen and industrial vehicle-mounted display device

Abstract

The invention discloses a method for controlling low power consumption of an industrial vehicle-mounted display screen and an industrial vehicle-mounted display device. The method comprises the stepsthat when the industrial vehicle-mounted display device receives a triggering condition of a low-power-consumption mode, a starting identifier normally started in a driving program of an industrial vehicle-mounted display screen is removed; the industrial vehicle-mounted display device sends a starting instruction of a low-power-consumption mode to the industrial vehicle-mounted display screen; the industrial vehicle-mounted display screen starts a driving program of the industrial vehicle-mounted display screen according to the starting instruction, and the started industrial vehicle-mounteddisplay screen is in a low-power-consumption mode. According to the method, after the display screen enters the low-power-consumption mode (such as power failure), the display screen enters the simpleunderlying driver during restarting, the linux operating system does not need to be started, the process time is short, the consumed power is low, and when normal starting is needed, the linux systemis started, the display screen is started, and user operation and parameter display are facilitated. Therefore, the system power consumption can be greatly reduced.

Description

technical field [0001] The invention relates to a vehicle-mounted display control technology, in particular to a method for controlling low power consumption of an industrial vehicle-mounted display and an industrial vehicle-mounted display device. Background technique [0002] At present, in vehicle applications, the vehicle battery supplies power to the entire vehicle electronic control system, and the cycle of engineering vehicles from production to storage to sale to customers may be long, especially when the market conditions are not good, and some may last several For one month or even more than one year, if there is no special person to charge the battery during the storage period, the battery may lose power or even be damaged due to the long-term power consumption of the entire electronic control system. [0003] Therefore, the main engine of the engineering vehicle puts forward low power consumption requirements for the on-board electronic control system to minimize...
