analog voltage signal meaning in Chinese

模拟电压信号

Firstly , a system was developed in functions to collect infrasound data , to transform analog voltage signal from detector into discrete signal by a / d card and to process the data by using methods of digital signal process
首先设计一套数据采集系统，次声波信号通过传感器被转换成模拟电压信号，通过a d板将其转换为离散的数字序列，输入计算机。利用数字信号处理的原理和方法对异常次声信号进行分析处理。
When it works , the system receives analog voltage signals produced by fruits from a pressure sensor , and these signals are sent to an a / d converter after they are amplified and filtered by the signal adjustment circuit . then , these analog voltage signals are converted to digital signals , which are sent to at89c51 microcomputer . after digital signals processed by the system software , every fruit ' s sorting level is deduced
工作时，系统通过压敏式压力传感器采集水果重量产生的电压模拟信号，将该信号放大、滤波后，送入a d转换器，转换后的数字信号进入at89c51单片机，经系统软件进行运算处理后，得出水果所属分选等级，并向分选开关发出开关量信号，实现对水果的动态称重和实时分选控制。
