BCS．I型烘干机控制系统的设计与实现中文摘要BCS-I型烘干机控制系统的设计与实现中文摘

要

集成电路(IC)生产过程中，电子部件需要进行高温烘烤一定时间后冷却再进行测试。目前市场上小型烘干机使用很不方便，不具备恒温计时及快速冷却等功能，也无法实现后台监测管理，仍靠人工观察和纸质保存信息。因此，开发一种能解决上述问题的新型烘干机系统对IC生产过程具有重要意义。

本系统是受苏州工业园区一家IC生产企业委托开发。整个系统主要由两大部分组成。第一部分为以Freeeasle M08HC908GP32 MCU为核心的嵌入式采集与控制系统，其硬件由MCU及其支撑电路、LCD、电位器、热电耦、三色报警灯、红外传感器、数据采集与控制模块等组成，嵌入式软件主要包括数据采集与滤波、三色报警灯驱动控制、LCD显示及串行通信等。第二部分为PC方的软件系统。主要功能是与MCU方进行串行通信、物理量回归、通过数据库操作实现对控制器历史状态的查询与管理等。

文中给出了控制器的串行通信、串口HUB、数据采集和A／D转换、LCD显示、继电器驱动等部分的硬件设计以及面向这些硬件对象的软件设计，阐述了PC方软件数据库结构与软件设计要点。重点介绍了串口HUB的硬件设计以及分段直线回归方法的设计与实现。

目前，新型烘干机系统在该公司得到了广泛的应用，现控制与管理4套烘烤机与冷却箱，可扩展至100套。本系统运行安全可靠，大大节约了成本，提高了公司的经济效益，具有良好的应用推广价值。

Abstract The Design and Implementation ofBCS-I Back Control System

The Design and

of BCS--I

Bake Control System

Abstract

IIl IC procedure of production,the dectron component for high-temperafum baking need

to maintain a Cel'tain period of time，and then test after cooling．But in the current market,small

oven

has no functions ofthermostats,rapid cooling and background monitoring management,and

artificial observation and paper-preservation is very inconvenient．So it has the important

si班6c锄ce to develop a IleW OVen system for the IC production to solve these problems．The system w勰el"lttxlsted to development by all IC production in the Suzhou it corporation comprises two main components．The first is the embedded acquisition and control system,its hardware contains MCU and support circuit,LCD，potentiometers，three-alarm-light,．infrared sensors,data acquisition and control module，and its embedded sofbvare contains data acquisition

and filtering,the drive control of three-alarm-light,LCD displaying and communication with PC etc．The second is PC’s son啊啊re that implements communication with MCU,the block straight-line regression,implementing the operation of the database on the

history ofstate controller's search and records management．

This paper shows the hardware design of serial communication,serial port HUB，data acquisition and A／D converting，LCD displaying and relay driving,and the S0ft懈design o f

these hardware object-oriented,describes the database structure and software design features of PC's software．It introduces the hardware of serial port HUB，the design and implementation of

the block straight-line regression in details．

Now,the new ovell system has been run steadily and reliably in this company．It can

control and manage 4 bakes and 4 cooling boxes，and can be expanded tO 1 00 bakes and 1 00

cooling boxes．It is proved that the system can save the cost and improve the company's economic efficiency．The application ofthis system is very promising and valuable．

Keywords：Bake T emperature Control System,Thermoelectric coupling，Infrared sensors，
