单片机多功能暗室控制仪的研制

The development of multi-function control system for darkroom based on a single-chip. computer

本文介绍了一种用单片机（８０３１）的多功能暗室控制仪。它能对医院放射科暗室内的照度、显影定影液的温度和循环报时单元进行自控。软件设计中使用了模糊数字Ｐ．Ｉ．Ｄ控制算法。提高了显、定影液的恒温精度。本仪器适用于中、小型医院放射科使用。

This paper introduces a multi-function darkroom system based on a single-chip-computer(8031).The system automatically controls luminosity,temperature of developing and fixation liquid,and time device that.cyclically gives correct time for the darkroom of radiological department of hospital Programmed instruction or learning uses dim P.I.D. count for high precision of constant temperature of developing and fixation liquid.This system is suitable for both smell and medium-sized hospitals.
