如何制作LabView控件，赖卫国整理，方便可行(How to make labview control, Lai Weiguo collation, convenient and feasible)

说明：  【智能四路交通灯控制系统模拟】 这款交通灯模拟系统基于labview软件开发，界面全部自己设计，简洁明了，功能多样化、实用化、具体化，最大程度还原真实的十字路口交通灯控制系统。在以往单纯的红绿交替变化上添加功能如下 1.数码管倒计时功能和灯光闪烁功能，四路人行道灯。 2.配备有操作板可以人为设置各路口交通灯的亮灭时间、闪烁频率，报警器频率，字符串提示。控制暂停和全灭。 3.数码管显示的系统实时年月日及时间。 4.显示以及交通管制中的7种模式（普通模式、三向禁行、南北通行、东西通行、夜间模式、维修模式、紧急模式）和每种模式持续的时间（用计时器来体现）。 现实中可以根据实际路况和需要进行有目地的调整，使交通更加通畅高效。([simulation of intelligent four-way traffic light control system] 1. Digital tube countdown function and light flashing function, four-way sidewalk light. 2. Equipped with operation panel, it can manually set the on / off time, flashing frequency, alarm frequency and string prompt of traffic lights at each intersection. Control suspension and total extinction. 3. The real-time date and time of the digital tube display system. 4. Display and seven modes in traffic control (general mode, three-way traffic prohibition, north-south traffic, east-west traffic, night mode, maintenance mode, emergency mode) and duration of each mode (reflected by timer). In reality, it can be adjusted according to the actual road conditions and needs to make the traffic more smooth and efficient.)

说明：  可实现TCP/IP连接后数据的读取与写入(TCP/IP data read and write)

基于Hilbert包络解调及倒谱分析法，在LabVIEW平台开发的齿轮箱故障诊断程序(Hilbert envelope demodulation, cepstrum analysis, and in LabVIEW platform developed by Gearbox Fault Diagnostics)

普源DS1000系列示波器labview RS232和GPIB通信驱动.(this is labview driver for Rigol DS1000.)

用于测量信号的振幅谱与功率谱，对初学LABVIEW做信号分析会有帮助。(Used to measure the signal amplitude spectrum and the power spectrum, signal analysis for beginners LABVIEW do help.)

一个LABVIEW登陆界面，可以实现到主界面的跳转(A LABVIEW login screen, you can achieve a jump to the main interface)

通过串口读取数据，利用示波器实现波形的显示，同时具有保存数据，回放图形的功能。(Read data through the serial port, use an oscilloscope to achieve waveform display, but also has to save the data, playback graphics.)

说明：  用labview对数据库进行访问链接的介绍和例程，初学者应该具备数据库知识。(Introduction to using labview for database access links and routines, beginners should have database knowledge.)

说明：  工业显示屏用于生产现场数据的显示与记录. 有与数据库交互与S7交互的操作.(Industrial display screen is used to display and record data of production site There are interactive operations with database and S7)
