由8051组成的单片机系统通常情况下，P0口分时复用作为地址、数据总线，P2口提供A15-A8即高8位地址，P3口用作第二功能，只有P1口通常用作I/0口。P1口是8位准双向口，它的每一位都可独立地定义为输入或输出，因此既可作为8位的并行I/O口，也可作为8位的输入输出端。当工作在输入方式时，对应位的锁存器必须先置1,才能正确地读到引脚上的信号,否则,执行读引脚指令时,若对应位的锁存器的值为0，读的结果永远为0。-By 8051, composed of single-chip microcomputer system under normal circumstances, P0 timeshare I reuse as address, data bus, P2 I provide A15-A8 high eight address, P3 mouth for the second function, I usually only P1 for I/0 I. P1 I was eight quasi-two-way port, it can be independent of each and every defined as input or output, it can be used as 8-bit parallel I/O port, can also be used as 8-bit input and output side. When the work in the input, the corresponding bit latch must first buy one in order to correctly read the signal pin, or pin the implementation of reading instruction, if the corresponding bit latch the value of 0, Reading the results of Forever to 0.

用一片ARM芯片，对电网中的谐波信号进行采集，然后通过GPRS发送给上位机，上位机对采集到的电网中的谐波信号进行分析。以确定电网中谐波的情况。-With an ARM chip, the harmonics of the grid signal acquisition, and then sent to the GPRS PC, PC to the power grid of the collection of harmonic signal analysis. To determine the grid in the case of harmonic.

PID是控制智能小车的经典算法在过程控制中，按偏差的比例（P）、积分（I）和微分（D）进行控制的PID控制器（亦称PID调节器）是应用最为广泛的一种自动控制器。它具有原理简单，易于实现，适用面广，控制参数相互独立，参数的选定比较简单等优点；而且在理论上可以证明，对于过程控制的典型对象──“一阶滞后＋纯滞后”与“二阶滞后＋纯滞后”的控制对象，PID控制器是一种最优控制-PID control of the smart car is the classic algorithm in process control, according to the percentage of deviation (P), Integral (I) and differential (D) control of PID controller (also known as PID regulators) is the most widely used as a automatic controller. It has simple, easy to realize, the application of a wide range of control parameters are independent of each other, the selection of relatively simple parameters, etc. and in theory can be proved that for a typical process control objects ─ ─
