摘　　要：对于模数转换模块来说,一般会采用八位的MCU,然后将其扩充成32K RAM,通过一个网络接口芯片可以实现同以太网的连接。在模数转换器模块,通常会配备可编程的放大器,并且在里面具有已标定好的程序,还存在许多数字滤波算法。通过分析剪裁TCP/IP协议,从而可以实现部分协议。利用浏览器,并不需要额外的编程,可以实现对于模拟数据的浏览,并且可在浏览器上面直接配置模块。For analog to digital conversion module,a eight bit MCU is generally used,and then expanded to 32K RAM.The connection with Ethernet can be achieved through a network interface chip.In the ADC module,it is usually equipped with a programmable amplifier and has a calibrated program in it,and there are many digital filtering algorithms.By analyzing the TCP/IP protocol,some protocols can be realized.With the browser,you don't need additional programming,you can browse for analog data,and you can configure modules directly on your browser.
