Embodiment Construction
[0022] Such as figure 1 As shown, the civil aviation airborne cockpit clock of the present invention includes a control assembly 100 , a display assembly 200 and a power supply assembly 300 . The control component 100 includes an MCU 110 , a button module 120 , a backlight adjustment module 130 , a clock module 140 , a communication module 150 , a display driver module 160 and a backlight control module 170 . The clock module 140 includes a crystal oscillator chip, a local time clock unit (the first clock unit) 141, and a coordinated world time clock unit (the second clock unit) 142. The two clock units can use two readable and writable real-time clock chips for Records time and provides data for local time and UTC. The communication module 150 includes a data transceiving unit and a level shifting unit. The receiving end of the data transceiving unit is interconnected with the ARINC429 bus inside the cockpit, and the transmitting end of the level shifting unit is interconnec...
