摘要
针对传统气体检测的系统软件滤波方法不能够剔除全部毛刺点的问题,提出一种基于先验规则均值滤波算法空气监测无线传感系统的设计。系统含有被测量光照强度、CO2浓度、温度、湿度,利用硅光电池、红外二氧化碳探头、复合温湿度传感器SHT21对四种参数进行数据采集,采用GPRS无线通信技术、Modbus协议、实现了现场监测传感器和上位机监控软件之间的通信,便于用户监控、查询和建立温室环境模型,从而有效地实现了对多个温室大棚内监测点数据的远程监控和环境分析。
Aiming at the problems that the traditional filtering software for greenhouses gas monitoring system is not able to remove all burrs point,a wireless monitoring system based on the prior rules average filtering for greenhouses gases is proposed. System includes measuring light intensity,CO2concentration,temperature and humidity. It uses silicon photovoltaic cells,infrared carbon dioxide sensor,complex temperature-humidity sensors SHT21 to collect four parameters. It uses the GPRS wireless communication technology and Modbus protocol to achieve detection sensors and realizes the communication between the monitoring software and users. So the system realizes the remote monitoring and environmental analysis on the greenhouse data from multiple points effectively.
