In the utility model, the contents are accurately displayed such as date, time, week and temperature, and the usage is convenient.

Description

The LED radio wave clock

Technical field

The utility model relates to a kind of LED radio wave clock.

Background technology

Radio controlled timepiece be in quartz electronic clock and watch, increased receive ratio long wave signal, data processing, from the functional structure of normal moveout correction, so just can receive the time reference signal that the cell site, ground sends with long wave, every radio controlled timepiece is after receiving this accurate time-code, through data processor processes, can be from the time error of walking of normal moveout correction quartz electronic clock and watch, controlled by unified accurate time-code, thereby realized the high-precision metering time of all radio wave clocks and shown the consistance of time.Existing radio wave clock function singleness, the piezoelectric effect of general using quartz crystal and the two poles of the earth tubular type liquid crystal display date, time and week, no display environment temperature etc., and there is no standby power supply, when cutting off market electricity, single-chip microcomputer can't operate as normal, and liquid crystal can not show, when last civil power, need reset the time, very trouble.

Summary of the invention

In view of the deficiencies in the prior art, the LED radio wave clock that provides a kind of function more, easy to use is provided the purpose of this utility model, and content such as this LED radio wave clock can accurately show date, time, week and temperature is easy to use.

To achieve these goals, the technical solution of the utility model is: a kind of LED radio wave clock, comprise single-chip microcomputer, it is characterized in that: described single-chip microcomputer is connected with RCC(Radio Control Clock) receiver module, driver module, temperature detecting module and crystal oscillator, described RCC receiver module receives the electric wave signal that launch in the radio station, the data-signal of the I/O mouth output of described single-chip microcomputer is lighted the charactron of LED display module behind driver module, described LED display module shows the data content from single-chip microcomputer output, described single-chip microcomputer also is connected with the control panel that is used for manually being provided with display data content, described single-chip microcomputer, the RCC receiver module, the LED display module is powered by power module.

Further, described single-chip microcomputer also is connected with standby power supply module.

Further, described control panel is the control panel of mechanical key formula or touch controlled key formula.

Compared with prior art, the utlity model has following advantage: (1) this LED radio wave clock adopts LED to show, have the brightness height, operating voltage is low, power consumption is little, miniaturization, the life-span is long, shock-resistant and steady performance, can clearly illustrate contents such as date, time and week, and this crystal oscillator can guarantee that this LED radio wave clock timekeeping performance is higher; (2) this LED radio wave clock is provided with temperature detecting module, accurately the temperature of testing environment and show by the LED display module; (3) this LED radio wave clock also is provided with standby power supply, and when cutting off market electricity, standby power supply is for the single-chip microcomputer operate as normal, and display screen does not show, need not reset contents such as time when last civil power.
