Problems solved by technology

[0003] The watches that people use in daily life are also regulated by the atomic time generated by atomic clocks. However, since different watches use different atomic clocks, there may be errors between the generated atomic times, making it inevitable that there are large or small differences between different watches. or small error

Embodiment

[0028] Such as figure 1 As shown, the second-generation Beidou satellite timing watch mainly includes the second-generation Beidou satellite signal receiving antenna, Beidou chip module, watch chip, hands, and power supply. Among them, the Beidou second-generation satellite signal receiving antenna, Beidou chip module, and watch chip are connected in sequence. The pointer is installed on the watch chip, and its rotation is controlled by the single-chip microcomputer in the watch chip; the power supply is respectively connected to the Beidou second-generation chip module and the watch chip. The mode selection button is directly connected to the Beidou second-generation chip module and the watch chip, and forms a parallel relationship with the branch circuit where the power supply is located. By controlling the switch state of the mode selection button, the control of the power supply can be realized, so as to realize the dual sleep and work of the watch. mode. In the present i...

Abstract

The invention discloses a second generation Beidou satellite time service watch, which belongs to the time service technology of the watch and mainly solves the error problem of the existing watch. The second generation Beidou satellite time service watch comprises a watch chip, a pointer arranged on the watch chip, a power supply source connected with the watch chip, and a second generation Beidou satellite signal reception antenna connected with the watch chip, wherein the second generation Beidou satellite chip module is further connected with the power supply source. The invention further provides an implementation method of the watch; the high-precision time service function of the Beidou satellite is applied to the watch so that an ordinary watch also has high-precision time service function; therefore, the practicability of ordinary watch is greatly improved.

Description

technical field [0001] The invention relates to a watch, in particular to a Beidou second-generation satellite time service watch and its realization method. Background technique [0002] my country's Beidou satellite navigation system has the functions of navigation, positioning, timing and short-message communication. It can navigate, position and time continuously and in real time around the clock. It has a wide coverage and is easy to use. The clock of the Beidou navigation satellite uses an atomic clock signal with high stability, so the timing of the Beidou navigation system is a high-precision time. At present, the Beidou timing receiving device can realize the reception of high-precision time signals. With the construction of my country's Beidou second-generation satellite navigation system, the size of the Beidou timing receiving device has been continuously miniaturized, which has continuously expanded its application range. [0003] The watches that people use in...
