To lower place machine and superordination machine, serial news report hardware and software realize the main body of a book having carried out design.

本文对下位机与上位机串行通讯的硬件和软件实现进行了设计。

Key location getting off place machine and the superordination machine serial news report being that entire system middle is the most important and degree of difficulty is maximal.

下位机与上位机的串行通讯是整个系统中最重要且难度最大的关键所在。

Supervisory control system reads superordination machine less than the workstation.

上位机监控系统读不到工作站。

Based on MCGS software of PLC control system, PLC hardware structure of the typical and superordination machine (ordinary PC or industrial IPC machine) through RS232 serial connection lines or RS485 communication.

基于MCGS 组态软件的PLC 监控系统的典型硬件结构中PLC 与上位机(普通PC 机或工业IPC 机)之间通过RS232 或RS485 串行线路连接进行通信。

Design middle in system , give a monolithic machine a signal by the keyboard scan, the monolithic machine is responsible for carrying out analysis on the signal and handling , passes on to superordination machine again.

在系统设计中，通过键盘扫描给单片机一个信号，单片机负责对信号进行解析和处理，再传给上位机。

Based on the characteristics of the chip we designed to control the hydraulic servo system for the core of this system, control circuit valve using digital potentiometer, through programming, automatic regulation resistance, high AD698 and accurately by an LVDT valve mechanical displacements converted single polarity dc voltage, through the simulation, the design of PID algorithm of closing valves, the degree of control system and superordination machine, realize the valve control circuit of adjustment and control.

基于上述特点我们设计了以单片机为控制核心的液压伺服阀控制电路，本系统采用数字电位器，通过编程自动调节电阻值，采用AD698 与LVDT 配合，高精确地将阀门的机械位移转换成单极性直流电压，通过模拟PID调节算法，设计实现了对阀门开合程度的控制，该系统与上位机进行通信，实现对阀门控制电路的调试及监控。

In the last two decades, morphological and electrophysiological studies have revealed that primary sensory information from the pelvic organs is conveyed to the lumbosacral spinal cord by the pelvic nerve, and then mediated by the secondary spinal neurons to supraspinal sites.

近二十余年的形态学和电生理学研究表明，盆腔内脏器的感觉是主要由盆神经传递至腰骶髓，然后由脊髓内的二级神经元向上位脑结构传递。

Ovary superior, 1-loculed, 3-5-carpelled, syncarpous, with 3-5 parietal placentae each with 1 to many anatropous ovules; style simple; stigmas variously shaped.

子房 上位，1室，3-5心皮，合心皮，3-5个侧膜胎座，没个胎座有一到多个倒生胚珠；花柱单一；柱头形状各异。

The servo controller regards TI Company DSP chip TMS320LF2407A as the main chip,has adopted standard ISA bus structure,has high -integration and high-agility,has accomplished in real-time complex boolean calculation and control algo- rithms during motion control,and can be used to realize high-speed and high-accuracy servo control for mul- tiple axis.

O前言以DSP为核心的多轴伺服控制器越来越广泛地应用在运动控制系统中，上位机只需对被控对象实施总体的控制和管理，而位置反馈信号的采集，闭环控制计算及控制量的输出均由伺服控制器完成，具有运算速度快，支持复杂的运动算法的特点，能实现高速度、高精度的位置伺服或轨迹

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
