Tower clock control system and tower clock power down time chasing method

Abstract

The invention provides a tower clock control system and a tower clock power down time chasing method. The system comprises a control device, a timing system, a clock core driver, a clock core motor, aHall sensor, a clock movement, a GSM wireless communication device and an interface circuit. The control device is connected with the timing system, the clock core driver, the GSM wireless communication device and the interface circuit. The clock core motor is connected with the clock core driver, the Hall sensor and the clock movement. According to the tower clock control system and the tower clock power down time chasing method, which are provided by the invention, at least two timing methods in GPS timing, RTC chip timing, clock timing of the control device, input timing based on an external key, and GSM-based input timing are used to carry out timing on a tower clock, so as to improve the accuracy of timing; according to the specific circumstances of power down, the type of time chasing is determined; a time chasing scheme is determined according to the type of time chasing; and when a specific time chasing process is carried out according to the time chasing scheme, the Hall sensor is used to judge the position of a pointer to realize accurate time chasing.

Description

technical field [0001] The invention relates to the field of large-scale clock control, in particular to a tower clock control system and a power-off time tracking method for the tower clock. Background technique [0002] Tower clock is an important role in public life, as a public facility in public places (such as stations, squares, airports, etc.), it provides convenience for people's lives. With the development of the economy, there are more and more tower clocks in urban buildings. However, most of the existing tower clocks use small-scale integrated circuits to control stepper motors for time tracking. The entire system is bulky and the accuracy is not high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tower clock control system and a power-down time tracking method for the tower clock, which adopts GPS timing, RTC chip timing, control device own clock timing, external button input timing, and GSM inpu...
