智能工业湿度控制系统设计 摘 要 本文展开了对智能工业湿度控制系统的研究。设计了基于单片机 AT89C51 的智能湿度控制系统，该系统主要由数字主控单元、水箱、抽水泵、加湿器、传感器等单元构成。数字主控单元主要由按键显示模块、压力、湿度采集模块、输出控制等模块构成。 按键显示模块为用户提供了人机交互的通道。用户可以通过键盘输入预先需要设定的参数，比如系统时间、排水时间等。LCD 显示模块能够显示时间和湿度数值、系统工作指示、电源工作指示、控制系统故障指示、以及水位高度、制水和停止制水的状态等信息。 为保证湿度控制的精度，系统选用了高精度的湿度传感器 HM1500 作为湿度检测单元。 在加湿器方面系统采用了国内外使用较多的超声波加湿器。 论文对所设计的高精度湿度控制进行了总结，讨论了系统设计的不足和改进 思路，为课题今后进一步的深入研究和系统性能的进一步提高奠定了基础。 关键词：工业加湿器 智能湿度控制系统超声波 加湿器 AT89C51 Abstract we began the research for intelligent industrial humidity control system. Our intelligent humidity control system is based on AT89S51 which is mainly composed of digital MCU, water tank, lift pump, filter, humidifier, sensors, reverse osmosis membrane etc. The digital control unit consists mainly of key display module, pressure and humidity acquisition module and the output control module, etc. Firstly, the key display module provides a way for human-computer interaction. The users can set the parameters in advance by keyboard, such as the system time, drainage time etc. Then the LCD display module can display the time and humidity values, system work instructions, power, control system fault instructions, and water level, water producing and stopping state. The pressure sensor is mainly used to detect external water information. The high humidity control precision is one of our key researches, so that a highly precise humidity sensor HM1500 is chosen as a period test unit in the system. The ultrasonic humidifier frequently used in foreign countries is adopted in the system. At the end of this thesis we have a conclusion about the disadvantage of the system design and improvement methods,.
