Aviation timing method and system for providing dual time display and UTC (Universal Time Coordinated) timing and sending

Abstract

The invention discloses an aviation timing method and an aviation timing system for providing dual time display and UTC (Universal Time Coordinated) timing and sending. A clock system used comprises a microcontroller (110), a button module (120), a clock module (140) and a communication module (150). The clock module (140) comprises a crystal oscillating unit (143) and a read-write MAN (Metropolitan Area Network) clock unit (141) for recording local time and a read-write UTC clock unit (142) for recording coordinated universal time, wherein the read-write MAN clock unit (141) and the read-write UTC clock unit (142) are respectively connected with the crystal oscillating unit (143). The method comprises the steps of: 1) carrying out initial setup of the system; 2) receiving a UTC data signal; 3) writing the UTC data to the clock module (140); 4) reading time and date data from the clock module (140); and 5) switching to display dual time and dual date. With the application of the technical scheme provided by the invention, display, timing and sending of double-timing and dual time can be realized.

Description

technical field [0001] The invention relates to the technical field of aeronautical clocks, in particular to an aeronautical timing system and method for providing dual time display and UTC time correction and transmission. Background technique [0002] The aviation clock involves aviation safety and has many special requirements. The Chinese invention patent with the application number 20101058198.5 and the invention name "A Multifunctional Aviation Clock" discloses a dual-display aviation clock combining mechanical pointer and LED digital. It can provide flight personnel with local time display and timing services. It cannot display UTC time and MAN time at the same time. The clock has no self-calibration function, and it cannot provide clock signals for other equipment on the aircraft. It cannot meet the needs of existing civil aviation airborne cockpit equipment. Functional requirements for timekeeping clocks. Contents of the invention [0003] The technical problem t...
