Abstract

The utility model discloses a time setting positioning device of pointer type radio-wave clock, which comprises a singlechip, a RCC receiving circuit, a demodulator, a enter key, an output driver and a LCD. Wherein, the RCC receiving circuit is connected with the calibrating signal input interface of the singlechip via the demodulator; each of other parts is connected with the relevant input or output interfaces of the singlechip; the calibrating signal is received by the RCC receiving circuit and is imported to the singlechip via the demodulator; after decided and treated by the singlechip, the signal drives the motor regulating pointer via the driven circuit and, and is imported to LCD. As the locate mode controls the LCD display through the same chip and the motor drives the pointer locate, the utility model can locate quickly, easy and accurately and distinguish the position of the pointer. Meanwhile, the product has a small and reliable structure.

Description

Indicator type electric wave clock to the time locating device

Technical field

The utility model relate to a kind of to the time locating device, especially relate to a kind of indicator type electric wave clock to the time locating device.

Background technology

Existing correction to ordinary clock to the time, generally be by manually regulating, some are hung on the wall clock, take off comparatively speaking and hang up cumbersomely, and manual adjustments is also not too accurate.Some high-grade radiowave timepieces are also arranged, adopt the photoelectricity locator meams to realize automatic adjusting, adopt the cost of products of photoelectricity locator meams manufacturing very high, and the correction location is not accurate enough.

The utility model content

The purpose of this utility model be to provide a kind of from the low indicator type electric wave clock of normal moveout correction accurate positioning and cost to the time locating device.

The purpose of this utility model can realize by following technical measures: a kind of indicator type electric wave clock to the time locating device, comprise that single-chip microcomputer, RCC receiving circuit, detuner, input button, output drive and the LCD LCD, above-mentioned RCC receiving circuit is connected with calibration electric wave signal input interface on the single-chip microcomputer through detuner, above-mentioned other each ingredients separately with single-chip microcomputer on corresponding I/O port be connected; By RCC receiving circuit receive clock calibration electric wave signal, through being input to single-chip microcomputer after the detuner demodulation, single-chip microcomputer is regulated pointer by output signal after the judgment processing through the output driving circuit CD-ROM drive motor, simultaneously the single-chip microcomputer output signal shows to LCD display, and time of always indicating with pointer time that LCD shows (time, minute, second) (time, minute hand) is consistent.

The utility model also comprises backlight and project circuit, hummer, separately with single-chip microcomputer on corresponding I/O port be connected; Be used to throw the demonstration time.

The utility model locator meams shows by same chip controls LCD and motor drives the pointer location, can locate fast, simply and very exactly, and differentiate the residing position of minute hand at that time, and utilize the product of the manner manufacturing, its structure, volume is less and reliable.

Fig. 2 is the circuit theory diagrams of the utility model specific embodiment.

Embodiment

As shown in Figure 1, a kind of indicator type electric wave clock to the time locating device, comprise single-chip microcomputer, RCC receiving circuit, detuner, input button, output driving, LCD LCD, backlight and project circuit and hummer, the RCC receiving circuit is connected with calibration electric wave signal input interface on the single-chip microcomputer through detuner, above-mentioned other each ingredients separately with single-chip microcomputer on corresponding I/O port be connected; By RCC receiving circuit receive clock calibration electric wave signal, through being input to single-chip microcomputer after the detuner demodulation, single-chip microcomputer is regulated pointer by output signal after the judgment processing through the output driving circuit CD-ROM drive motor, simultaneously the single-chip microcomputer output signal shows to LCD display, and time of always indicating with pointer time that LCD shows (time, minute, second) (time, minute hand) is consistent.Single-chip microcomputer is also controlled backlight simultaneously in addition and project circuit, hummer are used to throw the demonstration time and give the correct time.

As shown in Figure 2, entire product is divided two groups of power supply power supplies, a lithium battery; Other one group is the outer AA battery that can change at any time 2 joints (being VDD) of machine.Nominal voltage is 3V, and both can not switch by switch module U2 and triode Q3 simultaneously to the single-chip microprocessor MCU power supply.

When VDD=0 is an outside AA battery when not installing, the output OUTPUT=0 of switch module U2, triode Q3 conducting this moment, CR2032 gives single-chip microcomputer U1 (TM8706) power supply by the C-E of diode D1, triode Q3; When VDD=1, the OUTPUT=1 of switch module U2, this moment, triode Q3 ended, and internal cell can not have been powered by Q3.

Capacitor C 11, C4, C6, four electric capacity of C7 constitute booster circuit, provide 4.5V step pulse voltage for LCD work.Capacitor C 5, C9 are power filtering capacitor, capacitor C 8 is the reset capacitance of single-chip microcomputer U1, BZ1 is a hummer, driven by resistance R 1, triode Q1, LAMP is the bulb of pointer window projection light, and LED1 is the light source that projection is used, both are driven by resistance R 4, triode Q4 simultaneously, crystal oscillator X1, capacitor C 1, C2, C12 form master frequency oscillator 32768HZ, and 43, the 44 pin output of single-chip microcomputer U1 drives the pulse of movement motor, when normally walking during pattern pulse second hand of output in per 15 seconds beat once.Button MODE ,+,-for establishing the button of functions such as setting-up time, date, alarm clock, time zone.Button SOOZE is the projection lamp switch, whenever opens 5 seconds by pointer projecting lamp and projection under the normal mode, then enters the nap pattern by the SNOOZE key when alarm clock arrives.The ROTATION button is the Projection Display turning effort, whenever by a Projection Display Rotate 180 degree.Button S1_MSF is the selected element of RCC standard, and complete machine receives DCF signal (Europe) during disconnection, receives MSF signal (Britain) during short circuit.

The PON mouth is a control RCC accepting state, the RCC receiving function starts when PON=0, the signal of receiving by antenna is input to single-chip microcomputer U1 by the TCO mouth by TCO_IN and goes to identify time, date after resistance R 9, triode Q2, resistance R 10, capacitor C 10 shapings after decoding, show by LCD, export corresponding pulse simultaneously and make pointer forward corresponding position to.When PON=1, the RCC receiving function is closed.

After externally battery takes off, complete machine is grouped into 0:00, allow CPU time continue operation with the internal cell memory and with low-power consumption, after external cell loaded onto, complete machine ran to AM4:00 at once, and the beginning automatic reception, if successfully receive, then show at once and forward the current standard time to,, then walk back the singlechip CPU time if take defeat.
