| 摘 要： | 在数据采集系统经常要用到各类模拟量输出不一致的传感器，由于其输出不一致，造成了处理上的困难。采用软硬件结合设计了电平调节模块，用户操作Pc机向单片机AT89S52发送上升或下降命令，单片机AT89S52通过调节数／模转换器MAX521的输出，使相应传感器通道输出电平升高或降低，使各输出一致。

| Abstract: | In the development of the Master-Slaver data collection system, we often use all kinds of analog signals sensors. The sendouts of these sensors are repugnant, so it is discommodious to handle this data. To solve the problem, the author developed a module for adjusting electrical levels of the sensors to standardize by the use of sendout of AT89S52 through MAX521. This method has been applied in some data collection system. |
