本文是关于德州市巨泰机床制造有限公司生产的 T2225 型深孔镗床提出的 技术改造项目。其原本控制系统是由继电器与接触器组合而成的传统控制系统， 采用硬接线方式，因而存在着诸多弊端。例如产品精度不高，稳定性差，容易产 生废品；系统反应速度偏慢，存在延迟；控制线路杂乱，长时间工作运行会使其 线路表面绝缘层老化或破裂，极易造成短路，给设备和生产人员带来极大的安全 隐患。

在仔细对原本控制系统进行分析后，着重对原系统存在的问题和以后发展和 生产的要求，结合用户提出的要求，给出了采用 PLC（可编程序控制器）来控制 的方案。

本方案主要由可编程控制器、触摸屏、变频器及组态软件构成，它可以使主 电机软启动和平稳调速，实现电机速度可控化。依靠编程进行输入控制，实现控 制智能化、自动化。具备人机交互、故障记录功能，大大的提高了产品加工的能 力，减轻了劳动者的工作强度，降低了故障发生率，灵活度有了显著的提高，给 工厂带来了巨大的经济效益。

该改造方案实施效果良好，符合预期功能要求，具有良好的经济性和实用性， 适合推广应用，具备良好的发展前景。

T2225 Type Deep Hole Boring Machine Intelligent Control System Based On PLC

Abstract In recent years, with the rapid development of electronic and information technology, people's life has changed a lot。 At the same time, greatly promoted the progress of science and technology, so that the advantages of high-tech products embodied in all aspects of life, for the development of industrial production and progress to provide a powerful force。

This article is about the technical transformation project of DeZhou JuTai machine tool manufacturing T2225 type deep hole boring machine limited company produces the。 The original control system is the traditional relay and contactor control system consists of the combination of the hard wiring way, so there are many disadvantages。 Such as product precision is not high, poor stability, easy to produce waste; system response speed is too slow, delay; control line clutter, the long time use will the line surface insulation coating aging or rupture, extremely easy to cause a short circuit and equipment and production personnel to bring great security risks。

In carefully on the original control system are analyzed, focusing on  the problems existing in the original system and the later development and production requirements, combined with the requirements of the user, is given by PLC (programmable controller) to control scheme。

The program is mainly composed of programmable controller, touch screen, frequency converter and configuration software。 It can make the main motor soft start and speed control, and realize the speed control of the motor。 Depending on the programming input control, intelligent control, automation。 With human-computer interaction, fault recording function, greatly improves the ability of processing products, reducing the labor intensity, reduce the failure rate, flexibility has increased significantly, to the factory has brought enormous economic benefits。

The implementation of the reform program is good, in line with the expected functional requirements, with good economic and practical, suitable for promotion and application, with good prospects for development。
