【摘要】：随着我国医疗系统的不断发展以及壮大,各种精密设备也越来越多,这对水质的要求也就越来越高。在这种环境背景下,水处理系统在医疗系统中的应用显得尤为重要。在检验科、透析室、层流手术室、重症监护室等很多科室都需要安装水处理系统以达到用水标准。水质的严格控制直接关系到设备的正常运转,这也是避免设备高故障率以及多发医疗事故的必要措施。针对某医院的层流手术室水处理系统为研究对象,重新设计了医院层流手术室的水处理系统并进行了测试。文中论述的系统结合了国内外先进水处理系统设计经验,根据实地环境以及用水标准采用反渗透技术进行水处理。该层流手术室除了需要对原水进行过滤脱盐以外,还要求将水的电导率控制在要求范围之内,该设计采用PLC与模糊控制相结合的方法,解决电导率控制建立准确数学模型难的问题。在模糊控制算法上进行了优化与积分处理,使得电导率控制能够适应外界多因素的干扰,将电导率维持在要求范围之内。本文主要论述水处理系统的过滤方法、硬件设计、软件设计、算法的优化及分析等。该系统应用在医院层流手术室,电导率值基本稳定,误差维持在了规定范围之内,达到了手术室用水标准。
[Abstract]:Along with our country's medical system continues to develop and grow, all kinds of precision equipment is also increasing, the water quality requirements are increasingly high. In this context, the application of water treatment system in the medical system is particularly important. In the laboratory, dialysis room, laminar flow operation room, ICU and other departments you need to install a water treatment system to achieve the water standard. Strict control of water quality is directly related to the normal operation of the equipment, which is the necessary measures to avoid the high rate of equipment failure and multiple medical accident. According to the water treatment system of a laminar flow operation room of the hospital as the research object, the redesign of the water treatment system of hospital and laminar flow operation room the test system is discussed in this paper. Combined with the domestic and foreign advanced water treatment system design experience, according to the field environment and water standards by reverse osmosis water treatment. The laminar flow operation room in addition to the filtration of raw water, but also requires the conductivity of water control in the range of requirements, the design method of using PLC combined with fuzzy control, established the accurate mathematical model of conductivity control difficult problem. In the fuzzy control algorithm are optimized and integrated, which can control the conductivity to adapt to the interference of external factors, will maintain the conductivity in the range of requirements. Filtering method, this paper mainly discusses the water treatment system hardware design, software design, algorithm optimization and analysis. The system used in hospital laminar flow operation room, stable value of conductivity, maintaining the error within specified range, reached the standard of operation room the use of water.
