Longer Electronics Co.,Ltd--数码万年历IC

This company supplies digital ten thousand calendar IC (also to be called digital information to undergo IC, the good luck experience, LED clock IC, digital clock IC and so on).

Digital ten thousand calendar IC, is refers to uses the nixietube (LED) to demonstrate the year, month and day, the time, the week, the lunar calendar, the solar terms, the temperature, along the time, the countdown and so on, simultaneously has the integral point to report time and to decide the noisy function the specific IC (i.e. IC).

In the demonstration part, I take charge of IC to be possible to realize the basic display unit (refers to year, month, date and so on elemental area) many kinds of combinations. The week may use the unit nixietube, 7 photo tubes, the rice character nixietube to demonstrate that the unit nixietube may demonstrate 1-6, 8,1-7,2-8 three kind of situations. Brightness may in the daytime and the evening automatic transformation (white dawn, evening dark).

(Integral point reports time in the sound and decides the part noisily), the digital ten thousand calendar IC content sends Chinese pronunciation to report time with 20 many kinds of chord musics, may also design meets the domestic need, may also design meets the international need. Unique function: When comes the electricity (alternating current) the Times, may use in the electricity reminder.

In the overall plan cost aspect, besides digital ten thousand calendar IC, the nixietube and some essential components, does not have other commonly used actuation integrated circuit, like 74HC164,74HC595 and so on.

In the performance aspect, digital ten thousand calendar IC has the good quality, the stability, the time accuracy and the anti-jamming.

2、 Digital ten thousand calendar's electricity s is mad the performance index

(1) demonstrates brightness to be even, the greatest brightness has the enough brightness, does not glitter (including when integral point reports time or decides is noisy, when network voltage fluctuation)
(2) is in luck accurately, the mean diurnal error <0.5 second (has consummation performance besides IC also to need to choose good crystal, electric capacity, but also has in production time uses specialized equipment to carry on debugging calibration.)
(3) when normal work the complete machine power loss is small, the transformer or the stabilovolt (for example use) the long-firing operation does not give off heat. Waits for an opportunity when complete machine electric current <8uA, the guarantee battery backup can the long time maintenance time accuracy.
(4) the network voltage large scale fluctuation either the network voltage instantaneous (or vibrates continuously) when produces the strong jamming, ten thousand calendars do not halt, demonstrate not chaotic.

Explained:
1st, in the form said the hardware hypothesis function's meaning is refers to ten thousand calendars the default state function to be possible to jump the line through the hardware to establish, if on/afternoon LED instruction (12/24 hour) the default state may jump the line through the hardware to establish.

4、 May provide service (in view of existing IC)

(1) line board design;

(2) primary device and production equipment purchase channel introduction;

(3) technique of production instruction;

(4) visits the technical service;

(5) produces the technical training service;

Special explanation: Regarding purchases ten thousand calendar cassette mechanisms the factory and wants to produce ten thousand calendar cassette mechanisms voluntarily the factory, may send above the high school or the specialized middle school the cultural level staff member comes me to take charge of carries on training, Bao Jiaobao the meeting

5，Digital ten thousand calendar IC has custom-made the service

Continues the special function ten thousand calendar IC to have custom-made the development.
For example:
- Foreign language pronunciation and so on English, German ten thousand calendar IC developments;
- Conforms to pattern which the various countries' use custom's ten thousand calendars demonstrated;
- Radio automatic timing function; Does not use the worry time again the accuracy;
- Wireless doorbell;
- . . . . . .
