摘 要
 防火卷帘门是现代化建筑防火的必备设施，主要用于内墙，电梯间，通道厅堂，室内间隔等处，也可以作为外墙使用。兼有防火，防风，防雨和防盗等多种动能。
 本设计为防火卷帘门智能控制装置设计，既实现单片机自动控制防火卷帘门，本设计选用的cpu为89c52，最小系统具有复位和地址锁存功能。在数据存储器方面选用6264。I/O口扩展选用8155，内部含有两个8位和一个6位的可编程并行I/O口。在本设计中探测器选用P732型感烟探测器和TWDD型电子定温探测器，属于开关量输出，信号通过电阻降压传输给cpu，cpu接到火灾信号通过高音喇叭和发光二极管发出声光报警，然后发出指令启动三相电机，释放卷帘门，设有中间限位。卷帘门下降分两步，烟探测器报警卷帘门释放至中间限位处，温探测器报警卷帘门释放至底部。在卷帘门边设有手动按钮，手动控制装置应能够优先插入急停操作。三相电机通过继电器由单片机控制，本设计软件部分主要实现探测器自动报警并启动三相电机和按键中断功能。

Abstract
 The fire protection volume curtain gate is the modernized construction fire protection necessary facility, mainly uses in the inner wall, between the elevator, channel main hall, in room gap and so on place, also may take the outer wall use.Has at the same time the fire protection, windproof, rainproof and security and so on many kinds ofkinetic energy.
 This design for protects from fire the volume curtain gate intelligence control device design, also realizes the monolithic integrated circuit automatic control fire protection volume curtain gate, this design selects cpu is 89c52, the smallest system has the replacement and the address lock saves the function.Selects 6264 in the data-carrier storage aspect.The I/O part expansion selects 8155, the interior includes two 8 and 6 programmable parallel I/O part.The detector selects the P732 feeling smoke detector and the TWDD electron in this design decides the warm detector, belongs to the switch quantity output, the signal receives the fire signal through the resistance voltage dropping resistor transmission to cpu, cpu sends out the acousto-optics through the tweeter and the light emitter diode to report to the police, then sends out the instruction to start the three-phase electrical machinery, the release volume curtain gate, is equipped with the middle spacing.The volume curtain gate drops divides two steps, the smoke detector reports to the police the volume curtain gate release to the middle spacing, the warm detector reports to the police the volume curtain gate release to the base.Is equipped with the manual button nearby the volume curtain gate, the hand control equipment should be able first to insert stops the operation anxiously.The three-phase electrical machinery through the relay by the monolithic integrated circuit control, this design software part mainly realizes detector auto-alarm and starts the three-phase electrical machinery and the pressed key interrupt function.
  Key words: Monolithic integrated circuit; Detector; Three-phase electrical machinery;
