Pointer-type multifunctional intelligent clock

Abstract

The invention provides a pointer-type multifunctional intelligent clock, belongs to the quartz clock design technology field, and especially relates to a design method for a pointer-type multifunctional intelligent clock based on dual mode bluetooth. The intelligent clock comprises a clock face, pointers and a movement, and also comprises a movement gear case and a movement drive circuit. The movement drive circuit supplies power through a charging cell of 4.2V. A standby clock module is connected with the movement drive circuit. The movement drive circuit is connected with a temperature and humidity sensor module, a combustible and poisonous gas detection module, a PM 2.5 particle detection module and a low-power-consumption dual mode bluetooth interface module. The low-power-consumption dual mode bluetooth interface module is connected with an audio frequency decoding and power amplifier module and a TF storage card module. The pointer-type multifunctional intelligent clock achieves development towards intelligent, people-friendly and network household directions and which is an inexorable trend in the current high-speed network information-based society.

Description

technical field [0001] The invention relates to a pointer type multifunctional intelligent clock, which belongs to the technical field of quartz clock design, in particular to a pointer type multifunctional intelligent clock. Background technique [0002] There are three main types of pointer-type quartz clocks that can automatically control the calibration time that appear on the market at present: [0003] The first one is powered by 220V AC power supply, and the central master clock or NTP server in the network is obtained through the local Ethernet or 485 network or the Internet to obtain the standard time, and then automatically time service for the analog quartz clock terminal. [0004] The biggest disadvantage of this product: [0005] (1) It cannot be powered by batteries; (2) It needs to obtain time service through a wired network. Generally, it is necessary to lay communication network interfaces and power cables during the pre-decoration period of the user's occ...

AI Technical Summary

Problems solved by technology

[0005] (1) It cannot be powered by batteries; (2) It needs to obtain time service through a wired network. Generally, it is necessary to lay communication network interfaces and Power cables are mostly used in public places such as office buildings, hospitals, railways, and squares. They are not suitable for civilian use, and they consume a lot of power and are expensive. They require real-time online power supply

[0006]Second, the analog clock itself does not need a wired network, and directly receives GPS signal timing, but a long outdoor antenna is required, because it is generally received in homes and office buildings. No GPS information, not conducive to installation and construction, and requires 220V power supply online, not suitable for indoor independent applications

The biggest disadvantage of this product: (1) Although it solves the problem of outdoor antennas, it has great limitations. The coverage of wireless long-wave timing stations is not perfect. Even in areas that can be covered, the signals falling in buildings are very weak , there are strict requirements on the location of the address. When installing indoors, the shielding of the building to radio waves must be considered. It is necessary to manually hold a quartz clock and install it after moving indoors. Moreover, the decoding circuit is complex, the decoding time is long, and the efficiency is low.

(2) Different countries have different frequencies of radio waves, different decoding
