该程序为C8051F单片机的程序，其主要功能为： 单片机每一秒发送一次如下内容： 学号 = “各自的学号” 日期 = “年-月-日” 通信参数：19200bps,8N1   无硬件握手  看门狗定时器打开 (The program for the C8051F MCU procedures, its main function as follows: )

电子称重的实现首先是通过压力传感器采集到被测物体的重量并将其转换成电压信号。输出电压信号通常很小，需要通过前级信号处理电路进行准确的线性放大。放大后的模拟电压信号经AD转换进入主控单片机中，再将结果显示在人机界面。(The realization of electronic weighing is firstly to collect the weight of the measured object through a pressure sensor and convert it into a voltage signal. The output voltage signal is usually very small, which requires accurate linear amplification through the front signal processing circuit. The amplified analog voltage signal is converted into the main MCU by AD, and the results are displayed in the man-machine interface.)

实现雷达的信息接收的插件脚本，剩下的就是凑字数了，第一次上传东西，不知道有没有人看！(Achieve radar information receiving plug-in script, the rest is the word count, the first time to upload things, do not know if there is anyone to see!)

本文叙述了现在几种成熟的PID控制算法，对PID控制器的设计进行了研究，包括对控制器的硬件选型和软件设计，对合适的硬件给予详细的介绍，对程序的运行给出详细的程序流程图。 功能PID控制器的核心选用了ATMEL公司的AT89C51单片机，通过合适的外接硬件来完成模拟数据量的采集处理，数据的模数数模转换，液晶显示，按键输入等。(This paper describes several mature PID control algorithms, and studies the design of PID controller, including the hardware selection and software design of the controller, the detailed introduction of the appropriate hardware, and the detailed program flow chart for the operation of the program. The core of the functional PID controller is ATMEL MCU AT89C51, which completes the collection and processing of analog data, data analog to digital conversion, LCD display and keypad input through the appropriate external hardware.)
