摘要
为了保护在某些特殊环境(如大气受有毒物质严重污染区域)中工作的人员不受有毒物质的侵害,人们往往借助于某些防护装置,这些防护装置一般采用超压的工作原理,即保证防护装置内环境的气压高于外界大气压。本文针对现有超压控制仪的原理和缺点,提出了一种改进的内环境超压控制仪设计,并介绍了新型超压内环境控制仪的硬件结构和程序设计。
In order to protect operators who work at some special environments, such as zones badly polluted by toxicant, some protective equipments are used. These equipments normally employ the principle of positive pressure, i.e., ensuring that the air pressure of inner environment is higher than the atmospheric pressure. This paper puts forward a new design of positive pressure control instrument based on the current pressure control instruments, and introduces the hardware structure and software design of the control instrument.
