KD482或KD483是时钟打点报时专用集成电路,用它们制作的程控音乐打点报时器具有线路简单、调试简便、体积小及成本低的特点。该报时器到达整点钟时无需人工触发就可以自动奏出一段音乐,然后模拟钟声打出相应的点数。在晚上23点到第二天5点可以选择是否进行奏乐打点报时。整个打点报时走时精度高(日误差1s)、体积小,非常适合家庭自动报时使用,也可作为石英钟和LED电子钟打点使用。本文以KD483集成块制作的报时器为例介绍其制作使用方法。
KD482 or KD483 is a special integrated circuit clock ticking time, with their program-controlled music RBI timer with simple lines, easy commissioning, small size and low cost. When the timer reaches the whole hour, you can automatically play a piece of music without manual triggering, and then simulate the bells to play the corresponding points. At 23:00 to 5:00 the next day you can choose whether to play music strike time. Accuracy of the entire RBI strike time (day error 1s), small size, ideal for home use automatic timing, but also as a quartz clock and LED electronic clock RBI use. In this paper, KD483 integrated block production timer as an example to introduce its production methods.
