LED分光機(jī)控制系統(tǒng)設(shè)計(jì)

摘    要

本文設(shè)計(jì)介紹了LED及LED分光機(jī)的概念、現(xiàn)狀及發(fā)展趨勢(shì)，通過對(duì)分光機(jī)功能及結(jié)構(gòu)的了解和學(xué)習(xí)，分清各個(gè)系統(tǒng)的主要功能任務(wù)和相互關(guān)系；對(duì)整個(gè)LED的檢測(cè)、分選流程進(jìn)行初步設(shè)計(jì)，進(jìn)而選擇適合的控制方式；PLC控制系統(tǒng)可靠性高，抗干擾能力強(qiáng)配套齊全，功能完善，適用性強(qiáng)；系統(tǒng)的設(shè)計(jì)、建造工作量小，維護(hù)方便、易于改造；體積小、質(zhì)量輕、功耗低。將它用于分光機(jī)整個(gè)送料、檢測(cè)、分選系統(tǒng)的控制，既能滿足整個(gè)測(cè)量過程的精確性，又能實(shí)現(xiàn)給料、測(cè)量和送料過程的相互協(xié)調(diào)和配合工作；由此根據(jù)輸入輸出點(diǎn)的分配再對(duì)各個(gè)硬件系統(tǒng)進(jìn)行具體設(shè)計(jì)和選型，完成硬件系統(tǒng)的配置；而各個(gè)系統(tǒng)的連接通過電氣圖表示，可以直接進(jìn)行分光機(jī)的組裝和接線；軟件部分采用PLC梯形圖的編程方式，簡(jiǎn)單實(shí)用，實(shí)現(xiàn)了整個(gè)LED分選系統(tǒng)的自動(dòng)化。

ABSTRACT
 
This paper introduced the concept,the status quo and development trend of the LED and the LED sorting machine. Through the understanding and learning about the         function and structure of the LED sorting machine,we can distinguish the various systems of the main tasks and functions of mutual relations; Detection of the entire LED, the separation process preliminary design and then choose the appropriate control.The PLC control system is reliability, choose a strong anti-interference capabilities, improved function, the applicability.The system design, construction workload is small, maintenance-friendly, easy to transform small size, light weight, low power consumption.
It will be used to feed the whole machine by, detection, separation of the control system, can meet the entire process of measuring the accuracy, but also to achieve expected,  measurement and feed the process of mutual coordination and cooperation work. From the point based on input and output of the distribution to the various hardware systems for the design and selection, complete hardware system configuration. And the various systems of electrical connections through plans that can be directly carried out to the machine assembly and wiring. Some software used PLC ladder programming, is simple and practical realization of the entire LED automatic sorting system.

Key words： LED sorting machine, Auto-election, PLC, Hardware system
