数码变换器件通常用于显示装置及其它要求使用特殊数码的外部设备中,有的国外器件公司专门设计制造了各种数码变换器件供系列产品的配套使用。目前国内有的变换器件尚无生产,因此需要花费外汇,花费时间去订购。下面所介绍的方法,既简单易行,又省时省功省钱,不仅效果完全一致,和有的国外模块比较起来,几何尺寸也小得多。警如AD公司生产的BOM1615存贮模块,基本功能是将14位二进制码(对应全方位的360°角度量)变换成5位BCD码,满码显示为359.98°。因此它特别适合于轴角变换系统的快速实时显示。图1是某伺服系统中的一个轴角数据传送与显示电路。其工作过程简述如下。自整角机CX将天线指向数据(如方位角、仰角等)的模拟量送到转换电路SDC1704模块中去,(如接
Digital conversion devices are usually used in display devices and other external devices that require special digital products. Some foreign device companies specially design and manufacture various digital conversion devices for supporting the use of serial products. At present, there are still some domestic conversion devices without production, so need to spend foreign exchange, take the time to order. The method described below is not only simple and easy, but also saving time and effort, not only the effect is exactly the same, but also the geometric size is much smaller compared with some foreign modules. Alarm BOM1615 storage module such as AD company, the basic function is to 14-bit binary code (corresponding to all-round 360 ° angle measurement) into 5-bit BCD code, full code display is 359.98 °. It is therefore particularly suitable for rapid real-time display of shaft angle conversion systems. Figure 1 is a servo system in a shaft angle data transmission and display circuit. The working process is as follows. CX from the synchro antenna will point to the data (such as azimuth, elevation, etc.) analog sent to the conversion circuit SDC1704 module (such as access
