Abstract

The utility model relates to an electronic screen for displaying the time of world time zones, which is mainly composed of a calendar display section and a time display section which are controlled by a one chip computer. The calendar and the time are displayed in LED digital form, and the names of the time zones are displayed in letter form with lighting diode dot arrays. Consequently, the purpose of simultaneously displaying the standard time and the accurate date of the different time zones of the world is achieved.

Description

Time zone, whole world electronic display

The utility model relates to a kind of giant-screen electronic display that can accurately show all parts of the world etalon time and date simultaneously, and the timing that is widely used in public places such as hotel, airport, station, harbour shows.

Calendar clock when prior art is a kind of whole world district at present, it is combined on the big frame by a common quartz clock and two hemisphere zone timepieces, is pointer-type constantly during the district.Though this clock and watch also can show all parts of the world etalon time and date, timing shows not directly perceived, not eye-catching, operation inconvenience when using the school, and the high deficiency of cost, giving promote the wider application brings difficulty.

The utility model purpose is to overcome above-mentioned prior art deficiency, manufacture and design a kind ofly have the accuracy of timekeeping height, display screen is big, easy to operate, when having power down to walk automatically again simultaneously, power on and recover attractive in appearance, the novel electronic display of functions such as demonstration automatically.

The utility model is made of Single-chip Controlling part and screen body two large divisions, with reference to theory diagram 1, narrating its principle of work is: by special-purpose monolithic IC clock chip provide standard year, month, day, week, the time, branch the precise time data, read these data by single-chip microcomputer, and the difference during according to shown world district, carry out data processing, give the application-specific integrated circuit chip of display driver then, the real-time digital of display device shows when realizing whole world district.Also be provided with specially in the circuit simultaneously when providing power down to walk, power on and recover the power supply that shows the IC clock chip.The general structure that its screen body is realized is: manufacture and design a kind of rectangle screen big frame, on framework, be inlaid with by monolithic processor controlled electronic calendar and show and several (how much deciding according to will show the whole world district time) electronics show constantly, calendar is shown as current year, month, day, week, constantly be shown as the same day the time, branch.

The utility model has following characteristics than prior art:

1, accuracy of timekeeping height, long-term use error is little, 0.2 minute/year.

2, display screen is big, brightness is high, font is clear, bright-coloured eye-catching, visual range far reaches 60 meters.

Be benchmark during 3, with Beijing, can once proofread all electronics and show constantly.

4, easy for installation, have good thermal adaptability, can bear working temperature is-40～-60 ℃, optimum working temperature is-20～50 ℃.

Specific implementation structure of the present utility model can give to be described in detail with reference to the embodiment accompanying drawing.

Fig. 2 configuration screen general structure synoptic diagram;

The graphic screen general structure of Fig. 3 synoptic diagram.

Among Fig. 2, electronics key when display part, 4 control circuit boards, 5 schools constantly when 1 screen big frame, 2 electronic calendar display parts, 3 districts.

As shown in Figure 2, an electronic calendar display part (2) is inlayed on the left side (or top) at screen metal big frame (1), the right (or below) in big frame (1) is inlaid with Beijing, Tokyo successively ... New York etc. are display part (3) constantly, key (5) when the back of big frame (1) and side are equipped with control circuit board (4) and school respectively.Wherein calendar part year, month, day, week show with two LED, and part shows that with four LED spread pattern is constantly Regional title and colon show with a plurality of 16 * 16 * 4 LED array in the screen, the area title is divided into two kinds of fixed and varying types, display screen when display screen, varying type then are the whole world district during a kind of multi-region of fixed composition, the title number in time zone increases or reduces with software setting.Time zone title, calendar and showing constantly combine the year, month, day that just shows global different time zone exactly, week, the time, branch.

Among Fig. 3, key when 1 screen big frame, 2 world map patterns, 3 electronic calendar display parts, 4 electronics moment display part, 5 control circuit boards, 6 schools.

As shown in Figure 3, on screen metal big frame (1), be painted with world map pattern (2), electronic calendar display part (3) is inlayed in the appropriate location, below of left side screen big frame (1), when world map pattern (2) corresponding, respectively inlay electronics display part (4) constantly on the zone position, control circuit board (5) is installed in back at big frame (1), key when in the below, side of big frame (1) four schools being installed.

When using the utility model, extremely simple during the school, in the time of just can finishing whole school in one minute.

Claims

1, electronic display when a kind of displaying calendar and whole world district constantly is characterized in that the calendar in the time zone in the whole world, time zone and is simultaneously displayed on the giant-screen with digital form with the mode that makes up constantly.

2, when district whole world as claimed in claim 1 electronic display, its feature also is the calendar in time zone and constantly is presented at intuitively on the screen that is painted with the world map pattern.
