Civil aviation airborne cockpit clock

Abstract

The invention discloses a civil aviation airborne cockpit clock. The civil aviation airborne cockpit clock comprises a control assembly (100), a display assembly (200) and a power supply assembly (300), wherein the power supply assembly (300) is used for supplying needed voltage for the control assembly (100) and the display assembly (200), the display assembly (200) is an LCD (Liquid Crystal Display) which is provided with a backlight module, and the control assembly (100) comprises a microcontroller (110), a key module (120), a backlight regulating module (130), a clock module (140), a communication module (150), a display driving module (160) and a backlight control module (170). According to the civil aviation airborne cockpit clock disclosed by the invention, the local time and the UTC (Universal Time Coordinated) time can be switched, the civil aviation airborne cockpit clock can be in communication with an airplane control system and other airborne devices, the self-calibration can be carried out, the brightness of a display screen can be regulated, the endurance timing and the stopwatch timing can be carried out, the display power consumption is less, the timing accuracy is high, and the quick identification is easy.

Description

technical field [0001] The invention relates to the technical field of aviation clocks, in particular to a civil aviation airborne cockpit clock. Background technique [0002] An aviation clock is disclosed in the prior art, please refer to the Chinese patent, patent application number: 20101058198.5, the title of the invention is "A Multifunctional Aviation Clock", and the authorized announcement number: CN 102096370B. This patent document discloses a dual-display aviation clock combining a mechanical pointer type and an LED digital type, and the pointer will block the time displayed by the LED during operation. The revealed clock can only provide local time display and timing services for flight personnel, cannot simultaneously display UTC time and local time, has no self-calibration function, and cannot provide clock signals for other equipment on the aircraft, and cannot meet the needs of existing civil aviation aircraft. The functional requirements of the on-board cock...
