Description

Full-time electric clock

The utility model relates to Full-time electric clock, a kind of remote-controlled analog electronic clock that is used for family or public place of more clearly saying so.

Advantages such as existing digital dock has accurately, is easy to control, noiseless, but the effect that human eye is watched is so directly perceived not as analogue.And as machinery or electronic pointer clock, exist again wayward, noise arranged, be afraid of drawbacks such as vibration.The being seen simulated pointer clock with formations such as light emitting diodes in market, owing to can not indicate Hour Minute Second simultaneously, the effect that human eye is watched is still not as traditional mechanical indicator clock.

Purpose of the present invention, be to overcome the shortcoming of above-mentioned two kinds of clock and watch, simulate traditional pointer and indicate Hour Minute Second simultaneously with the unit that singly shows of individual pen, wherein hour hands show with three adjacent unit, minute hand shows that with individual unit second hand shows with the individual unit that flashes.Small time taking on the clock dial was with system conversion automatically in 24 hours, and clock dial can be used as and shows that secondary clock connects remote control with cable many places.

For achieving the above object, the utility model is made up of simulated clock simulation clock dish, thermometer, button, power supply and the casing of single-chip microcomputer and control thereof.When wherein single-chip microcomputer can be accepted the school of external standard time sign indicating number, also be connected to not power down clock chip, also can read in temperature data displays temperature on clock dial of thermometer, also can adjust time or date, also can put and decide time switch by button.This part circuit can with clock plate on a plate, also can separate, clock plate is connected, by the single-chip microcomputer remote control with cable many places as independent secondary clock.Single-chip microcomputer can be exported the above universal time clock signal in eight time zones simultaneously, shows a plurality of zebra times for the clock plate that inserts respectively, also can sequentially show the time all over the world, and place name is simultaneously displayed on the clock plate.The circuit of clock plate is made of shaping circuit, monostable circuit, shift register, code translator, addressable latch and display, and such circuit structure element is arranged easily, and is compact reliable.Wherein, shaping circuit gives the anti-phase data input pin of delivering to shift register of shaping with the pulse-length modulation sign indicating number of single-chip microcomputer output, also send into simultaneously monostable circuit, make it to produce respectively the pulse of two kinds of width, a kind of narrower shift pulse as shift register, a kind of broad behind 38 code translators, as the latch pulse of addressable latch after pulse train has sent, just shift register is static, first four of the eight bit data of its output is energized to the addressable latch of choosing behind 38 code translators, back three bit data are the inside addressing of addressable latch, and last one digit number is according to importing as latch data.Correspondingly like this have 64 independent outputs, 60 display units of supplying with 60 five equilibriums on the whole garden of clock plate wherein, 1 switching signal as 24 hours scale making nixie displaies, the number of the small time takings such as 12,15,18,21 in the small time takings such as 3,6,9,12 in this signal deciding morning and afternoon, this number can be reduced to the display unit of non-number.Tens display units on the clock plate are directly driven by integrated circuit, shared one of its current-limiting resistance.In addition, four on the head of shift register output can gating another organize 38 code translators, energize and latch data for another group latch then, be sent to and imitate pendulum luminotron and matrix display.7 imitative pendulum luminotrons are arranged in that to be the garden arcuation on the clock plate luminous in turn, and swing back and forth once a second.Two buttons are arranged on the clock plate, when pressing " moving key ", it is motionless that then imitative pendulum luminotron is parked in a certain position, the function of this position representative is respectively timing, transfer to divide, transfer second, regularly, locking etc., can make luminotron move one and select a certain function by " moving key ", this moment by " adding key " then this function promptly come into force, promptly or add one hour or set and remove regularly etc., when for a long time not during button, show return automatically normal.

In order to increase the combination property of this clock, on clock plate, also be provided with digital thermometer and show temperature at that time.Light activated element also is housed, the luminosity of clock plate is regulated automatically with ambient light illumination.Hummer also is housed in the clock, gives the correct time or the timing locking by the Single-chip Controlling integral point.The power supply of clock plate can be adopted the mode of mirage common-battery, and promptly data ride on the power lead and transmit.Driving circuit on the clock plate can adopt high voltage circuit to drive the high-voltage large current display device.Matrix display on the clock plate is used to show area, year, month, day or the temperature etc. of universal time.To bigger demonstration occasion, available many Full-time electric clocks combination shows, display unit can adopt element address coding and decoding conllinear mode, to improve simple and direct property, the reliability of circuit, the luminous or not reflective object of the plant of the also available electromagnetism turnover panel of display unit, electrochromism, different colours, water spray flower etc. itself is represented.

Task of the present utility model comes to this and finishes.

The utility model Full-time electric clock is simulated traditional clock pointer with the display unit of individual pen and is indicated Hour Minute Second simultaneously, small time taking on the clock dial was with system conversion automatically in 24 hours, both can do for a short time as table clock, being used for automobile, cabin etc. locates, can do very greatly again, as huge metope clock, easy to connect, of many uses.Owing to be annular arrangement, can decorate easily around various article such as picture frame, wall, sign etc., have practicality and artistic value concurrently.
