和电路

Because the Hall probe circuit, magnetic-flux meter circuit and extension measurement circuit share the same A/D converter, but MAX110 only have two channel, so the system use CD4052. CD4052 is the analog switch controlled by microcomputer, which can switch the three input channels. The singles is passed to microcomputer after A/D converted.

所有与模拟电路有关的低频接口控制线都采用光电耦合器TPL521进行隔离，而频率较高采用6N137构成单片机相关外围器件的隔离，以便抑制数字电路的尖脉冲和其他噪声对模拟电路产生干扰，提高系统的信号噪声比。

Hardware design includes equipment selection ,I/O address assigning ,exterior input circuit designing ,exterior output circuit designing , the joint circuit of sensor etc .

This is the logic circuit of a microcomputer and microprocessors are often the same as a microcomputer.

这是微型计算机的逻辑电路，微处理器的逻辑电路是和微型计算机的逻辑电路一样的。

Just pay attention to that the gains for plus and minus signals are the same, and the area of the signal around zero. I checked the LM35, the accuracy is good, but does it need 2 diodes in series to measure the temperature lower than -20 degree C? You could consider TC1047A that I used before, it doesn't need any other component, and it can go directly to A/D.

我用4051是想将AD620的＋/-输出信号不通过绝对值电路，而是接一个反相电路，反相前后的信号通过4051和极性判断电路有选择的将信号的绝对值电压再送入AD，用这个方法也能处理温度传感器LM35的输出信号，我想这是个比较安全的方法了吧！

It consists of many ele- mentary pulse networks such as: Transistor forming and shaping circuit,trrnsistor blocking oscillator,multivibrator,time delay circuit and "and" gate,etc.
