摘要
系统采用单片机技术进行现场模拟电压采样处理并进行数据传输,将外部采进来的模拟信号转换成数字信号,经过调制、滤波、解调之后,在另一单片机最小系统板将采集的数据结果显示出来,完成了整个数据采集与传输过程.系统具有发送端设定8路顺序循环采集与指定某一路采集的功能.
The system adopts the technology of single-board microprocessor to s ample and handle the scene's analyogical voltage, and also transmit signals. swi tch the analog signals which is sampled from exterior to the digital signals, af ter modulation, sieving waves, and demodulation, the sampling data are displayed on the another smallest single-board microprocessor system-board, so that the whole process is accomplished. The system can enactment eight-way circular col lection in order in the sender.
