摘要
转换模块采用8位MCU,扩充32kRAM,经网络接口芯片与以太网连接,使用24位Σ-Δ模数转换芯片,实际分辨率不低于17位。模块内有可编程放大器,嵌有标定程序和多种数字滤波算法。经分析裁剪TCP/IP协议,在模块中嵌入裁剪后的协议,实现部分协议。使用网络浏览器,无需编程,能直接浏览模块采集到的模拟量数据,可在浏览器上配置模块。
The A/D Modula uses MCU of 8-bit and 32kRAM extended .It connets with the ethernet through the chip of the network interface and uses ∑-A A/D chip of 24-bit so that it can get the resolution higher than 17 bit.There are amplifier v,＇bo can be programed and the program be pre-established procedures and a lot of algorithms about filtering in the modula .We must streamline the TCP/IP protoeals and embed the protocal who can be streamlined .we can use the Web browser to observe the simulation data collected from the modula and configure the modula through the browser, do not need to program.
