- 摘要:
- 为实现对医学小气候的空气质量监控,采用多种生物医学传感器和数据采集技术,提出一种有害气体智能监测方案。该方案采用现场可编程门阵列(FPGA),方便对传感器的非线性和时间滞后性进行校正,实现对小气候空气质量实时监测; 同时,采用模糊控制算法,根据《室内空气质量标准》GB/T18883-2002的要求,通过空气调节和净化,实现对室内空气质量的实时调控。测试表明,该套方案的可靠性和智能化程度高,适用于医疗机构、大会堂、交通枢纽等人流密集的公共场所。
- Abstract:
- In order to realize the air quality monitoring of the medical microclimate, a variety of biomedical sensors and data acquisition technology are adopted, and a scheme on intelligent detection is proposed in the paper. The FPGA is used to improve the nonlinear and time delay of sensor parameters. The real-time monitoring of the air quality in microclimate is achieved based on the technology. Meanwhile, fuzzy control algorithm is selected to control the indoor air quality with the air conditioning and purifying meet the criterion of the "indoor air quality standards" GB/T18883-2002. The practical test shows that this scheme is high reliability and intellectualized, and fit for the medical institutions, hall, transportation hub and other crowded public environments.
