本装置是一个以HT46R71D 为主芯片，配合传感器组成的汽车轮胎气压检测装 置，最终取高三位有效值于LCD 显示，有四种显示单位供切换（Psi、Bar、Kpa、 Kgf/cm2）。本装置仅为参考范例，使用时，为提高准确度，建议多量测些组数 据来构建Sensor Output Voltage - Discharge Time (V-T)表格，并作相应校准。-This device is a HT46R71D-based chips, with sensors detecting vehicle tire pressure devices, and ultimately take the high-three RMS in LCD display, there are four types of display units for switching (Psi, Bar, Kpa, Kgf/cm2). Only reference to an example of the device, when used to improve the accuracy of the proposed多量measured set of data to build more Sensor Output Voltage- Discharge Time (VT) forms, and the corresponding calibration.

RS-485接口具有较强的抗干扰性，数据传输的距离较远，在一些应用中常常需要把RS-232标准的信号转换为RS-485的标准信号进传输。图中所示电路允许数据在RS-232/RS-485这两个不兼容的串行数据接口间传递。传输速度为480波特时，传输距离可达1750米。图中双RS-232收发器IC1将主机(PC)输出的RS-232电平转换为TTL电平，驱动高速RS-485收发器IC2 的输入，倒相器使IC2、IC3在受到起始位时被激活。-RS-485 trying to lay all the thoroughly bleed at the nose picking up the birthday 扰 fern cavity 强 ， Chu Huai basin cavity beat escapement for the birthday candle远Now ， Which instance, using Beckmannia中
