Description

A kind of LED clock chi

Technical field

The utility model relates to a kind of LED clock chi.

Background technology

Ruler is the teaching and schooling apparatus imparting knowledge to students and often use in students'learning, existing ruler, although structure is fairly simple, but function ratio is more single, it is only a kind of instrument being used as to measure, and when student takes an examination, because there is the restriction of test time, student is in order to hold the distribution of test time, usually can wear wrist-watch and see the time, or see clock in classroom, wear wrist-watch or religion indoor suspension clock, dispersion energy is all needed to go the time of seeing, be unfavorable for that examinee focuses one's attention on and carry out answer, and ruler is also the standing apparatus in examination hall, therefore, design the clock chi of a kind of ruler and clock combination, both be convenient for carrying, be convenient to again student concentration answer, also can know rapidly the concrete time simultaneously, be convenient to the distribution of examination assurance time.

Utility model content

For problems of the prior art, the purpose of this utility model is to provide a kind of LED clock chi.

Described a kind of LED clock chi, comprises ruler body, it is characterized in that described ruler body is pasted being provided with transparent paster, and with scale on described paster, the inside of described ruler body is provided with LED lamp bead and controls the control system of LED lamp bead.

Described a kind of LED clock chi, is characterized in that the side of described ruler body is provided with a red LED lamp pearl at interval of 1cm from 0 scale, is provided with 24 red LED lamp pearls altogether, red LED lamp pearl represent the corresponding time time.

Described a kind of LED clock chi, is characterized in that the opposite side of described ruler body arranges a blue led lamp pearl at interval of 0.5cm from 0 scale, and for being provided with 60 blue led lamp pearls, blue led lamp pearl represents dividing of corresponding time.

Described a kind of LED clock chi, is characterized in that the length of described ruler body is 30cm.

Described a kind of LED clock chi, it is characterized in that described control system comprises controller, described controller is connected with clock module, battery, LED lamp bead.

The utility model novel structure, reasonable in design, by arranging red LED lamp pearl in ruler inside and blue led lamp pearl represents Shi Hefen respectively, examinee is facilitated to know the concrete time in time on examination hall, the ruler of this kind of vibrational power flow simultaneously, easy to carry, diverse in function, is convenient to examinee and focuses one's attention on answer.

Embodiment

Below in conjunction with Figure of description, the utility model is described in further detail:

As shown in figures 1 to 6, a kind of LED clock chi of the utility model, use when being mainly used in examination, comprise the ruler body 1 that length is 30cm, ruler body 1 is pasted and is provided with transparent paster, with scale on paster, the inside of ruler body 1 is provided with LED lamp bead 2 and controls the control system of LED lamp bead, this control system comprises controller 3, and controller 3 is connected with clock module 4, battery 5, LED lamp bead 2.The side being specially ruler body 1 is provided with a red LED lamp pearl at interval of 1cm from 0 scale, is provided with 24 red LED lamp pearls altogether, red LED lamp pearl represent the corresponding time time; The opposite side of ruler body 1 arranges a blue led lamp pearl at interval of 0.5cm from 0 scale, is provided with 60 blue led lamp pearls altogether, and blue led lamp pearl represents dividing of corresponding time.

LED lamp bead application matrix keyboard principle has saved I/O mouth resource, and I/O makes line, and multi-way switch exports and makes alignment.Be divided into 2 row, 1 row has 24 LED, red, during expression; 1 row has 60 LED, blue, represents and divides.The utility model can be used as ruler, can be used as again clock (when can show, dividing), be suitable for using in student examination process.

Utility model works principle: the base plate schematic diagram being illustrated in figure 1 LED clock chi, sticks light transmissive material, paster with scale numeral on the surface of this base plate, when relevant LED lights, time corresponding, point numeral can show, i.e. current time.The scale of ruler on the left of such as Fig. 1, total scale 30cm, scale 0-23 place is each LED, and in figure, arrow represents LED, red, representative " time ".As represented " dividing " on the right side of Fig. 1, arrow represents LED, blue.Such as, current time is 11: 12, then the red LED at left scale 11 place is bright, and the blue led at right scale 12 place is bright simultaneously, and the known current time of user is 11: 12.The time range of display when being 0 when 0 point-23 59 points.

Clock module circuit diagram adopts DS1302 circuit as shown in Figure 3: perpetual calendar clock chip, and after completing Initialize installation by program, as long as the button cell that standby electricity source VCC2 connects has electricity, chip can self-clocking, realizes perpetual calendar clock function.As long as controller reads the data of DS1302 by SPI interface, the time data information that current date Hour Minute Second etc. is detailed can be known.The utility model only needs " time ", " dividing " data

As shown in Figure 4, depict expression " time " the circuit diagram of 23 LED, have employed CD4051 Multiplexer Channel HS1-HS8 as alignment, the HSEL1-HSEL3 of controller is as line, and CON1 selects control line as the sheet of C4051.Can realize the control of 3*8 totally 24 LED like this, the utility model controls 24 LED, and therefore LED numbering is D1-D24, when representing 0-23 respectively.Citing: set controller to read current time as 21: 15 from clock circuit, then D10 should be made to light, so controller makes CON1=0, HSEL3-HSEL1=101, i.e. HSEL3=HSEL1=1, HSEL2=0.With seasonal H3H2H1=001, the HS2 passage of CD4051 (U1) and X is namely chosen to connect, so D10 lights.59 the LED circuit figure representing " dividing " in like manner, do not draw.The determinant of 8*8 can control 64 LED, and the utility model controls to represent the LED divided and is numbered L1-L60, corresponding point 0-59.

The utility model make use of the common function of controller, and these are all prior art, does not need to carry out separate procedure and writes, do not repeat them here.
