Embodiment Construction

[0015] In order to better illustrate the realization side of a kind of pointer type CDMA quartz clock control method of the present invention, its specific realization method is described as follows (see figure 1 ):

[0016] A pointer type CDMA quartz clock control method The whole system includes a movement drive circuit module 4, a disposable high-energy lithium sub-battery module 1, a CDMA timing module 2, a spare clock module 3, a jumping second gear box 5, a second sweeping gear box 6, Segment LCD Module7.

[0017] A control method for an analog CDMA quartz clock, which uses a disposable high-energy lithium sub-battery module with an output voltage of 3.6V to supply power to the drive circuit module of the movement. The second-sweeping movement and the second-jumping movement are powered, and the quartz clock pointer is driven to run. The movement drive circuit module is also connected with a CDMA timing module, and the CDMA timing module controls the second-sweeping...

Abstract

The invention relates to a control method of a pointer type CDMA quartz clock, and belongs to the technical field of clock production and processing. According to the control method of the pointer type CDMA quartz clock provided by the invention, the pointer type clock is mainly subjected to timing by taking a precise satellite time provided by a CDMA mobile phone network signal which is wide in signal coverage and great in signal intensity as a standard time by virtue of a CDMA circuit module. The method does not severely require the geographic position of the quartz clock as that of a radio controlled clock. The position is random. Even if the clock is mounted in a building, the CDMA signal is also powerful, so that the defect that the radio controlled clock cannot receive weak signals or mistakenly decodes the signals is avoided effectively. Moreover, a receiving antenna is built in the quartz clock like that of a mobile phone, so that the clock is very easy to mount and suitable for various occasions such as domestic use and office. The CDMA circuit module provides the precise satellite time and the theoretical error of the provided time is nearly zero while the actual error does not exceed 5 milliseconds.

Description

technical field [0001] The invention relates to a method for controlling an analog CDMA quartz clock, which belongs to the technical field of clock production and processing, and in particular relates to a method for controlling an analog CDMA quartz clock. Background technique [0002] The maintenance-free analog quartz clocks that can automatically adjust the time that appear on the market mainly include area network time service quartz clocks, GPS quartz clocks or radio wave quartz clocks. [0003] The technical disadvantage of the regional network clock is that it needs to receive the time sent by the master clock server in various networks or the standard time of the NTP server through the 485 network or Ethernet local area network, or the CAN network to realize automatic time calibration, and the error is large , generally within 1 second, communication interfaces and cables need to be laid during the pre-decoration period of the user’s occupancy in the building.
