把BCD码翻译成显示16进制数或不同状态的方法大多是在计算机的数据处理中及电子线路的控制中应用,目前还没有把这种译码的方法做成单独的教具玩具使用。本新型的目的就是把BCD码—16进制数这种译码的逻辑关系做成一种教具玩具来使用。本新型的技术特征在于用集成电路4—16线译码器或BCD—7段—16进制译码锁存推动器,配上显示器和集成电路音乐片及喇叭来演示这种逻辑译码的关系并发出音乐。 说明

本实用新型是用电子器件和显示装置组成的具有知识性和音乐趣味性的智力电子教具玩具。

把0000-1111这四位二进制数即BCD码用电子器件翻译成1-16线呈不同状态或直接显示16进制数的方法大多是在计算机的数据处理中及电子路线的控制中应用。目前还没有把这种BCD码-16进制译码的逻辑关系做成单独的教具玩具,供学习和玩使用。

把BCD码翻译成16线呈不同的状态或显示16进制数可以用电子器件搭成,也可以采用现有的集成电路4-6线译码器74154或采用BCD-7段-16进制译码锁存推动器MC,14495。但这只是一些功能器件,还不能用来作为教具玩具直观的演示这种逻辑关系。

本实用新型的目的是把BCD码翻译成1-16线呈不同显示状态或显示16进制数的方法做成一种单独的演示器来演示这种逻辑关系,另外在该装置中配上集成音乐电路片使它在演示时产生音乐,以增加它的趣味性。这种演示器可以作为教具供初学计算机基本知识的人学习BCD码使用,也可以供儿童当作玩具使用。

本新型是这样实现的:采用4-16线译码器74154作为翻译器,输入部分用4个“断开”或“接通”表示“0”或“1”的开关作为BCD码的输入接到74154的输入端,这4个开关可以组成16种不同的状态,那么在74154的输出端配上驱动电路带动指示灯或继电器就可得到16个其中之一的灯亮或不亮,继电器动作或不动作来显出对应于BCD码所表示的16进制数的演示,也可以采用BCD-7段-16进制锁存译码推动器MC,14495,在输出部分配上共阴极7段数码管直接显示16进制数,另外,再在该装置中配上音乐电路片和喇叭使它在演示时发出音乐。

本新型所演示的BCD码-16进制数之间的逻辑关系是电子计算机的基本知识之一,因此它可以作为教具使用;也可以作为知识性、智力及趣味性的玩具使用。本新型机壳可以用塑料制作,输入用四只开关,用一只集成电路译码器,输出配上驱动显示器,另外再配上一只集成电路音乐片和喇叭就可实现。本新型使用器件不多,电路简单,成本低,容易制作,特别适合于批量生产。

本新型的制作方法及电路框图由以下的实施例及附图给出。

附图是根据本新型提出的音乐智力电子教具玩具的电路框图。

下面结合附图详细说明本新型提出的具体实现方法。

该新型包括用四个开关组成BCD码输入〔1〕,开关和译码器〔2〕相连接,译码器和显示器〔3〕相连接。另外再配一片集成音乐电路片〔4〕和一只喇叭〔5〕,电源〔6〕和电源开关〔7〕。

在四个开关完成选定的BCD码后,按下电源开关〔7〕译码器〔2〕即把开关组成的BCD码翻译成所显示的状态或数字在显示器〔3〕上显示出来,同时音乐电路片〔4〕和喇叭〔5〕的电源接通并发出音乐。

Yesterday, while I was at work, my cousin stole my apple ipad and tested to see if it can survive a thirty foot drop, just so she can be a youtube sensation. My iPad is now broken and she has 83 views. I know this is entirely off topic but I had to share it with someone!|

Hi there! I know this is kinda off topic but I was wondering which blog platform are you using for this website? I'm getting sick and tired of Wordpress because I've had issues with hackers and I'm looking at options for another platform. I would be great if you could point me in the direction of a good platform.|

An interesting discussion is definitely worth comment. There's no doubt that that you ought to publish more about this issue, it might not be a taboo matter but generally folks don't speak about these subjects. To the next! Many thanks!!|

When I originally commented I seem to have clicked on the -Notify me when new comments are added- checkbox and now whenever a comment is added I get 4 emails with the exact same comment. Perhaps there is a way you can remove me from that service? Cheers!|

You actually make it appear really easy along with your presentation but I in finding this topic to be actually one thing that I feel I might by no means understand. It sort of feels too complicated and very extensive for me. I'm looking forward in your next publish, I'll attempt to get the cling of it!|

Currently it appears like Movable Type is the top blogging platform out there right now. (from what I've read) Is that what you are using on your blog?|

Its like you learn my thoughts! You seem to know so much approximately this, such as you wrote the e-book in it or something. I believe that you simply could do with some percent to drive the message house a little bit, but other than that, that is wonderful blog. A fantastic read. I'll certainly be back.|
