Design of monitoring environmental factors of endangered plant Paphiopedilum armeniacum

【目的】实时了解杏黄兜兰所在生存环境的各项参数,掌握其最佳生长环境,为进一步实时控制其环境参数,促进物种的繁殖生长,防止物种的濒危灭绝,保护生态环境提供参考。【方法】运用AT89C51单片机为控制处理核心,以杏黄兜兰生长环境的温度、湿度、光照强度为监测参数,选用DS18B20温度传感器、HS1101湿度传感器、TSL235光频转换器进行数据采集,并采用PTR2000模块实现短距离无线传输。【结果】AT89C51单片机可实现对温度、湿度、光照强度等多个环境因子的共同监测,将环境因子值显示于数码管,传输距离可达300m。【结论】设计方案适用于杏黄兜兰所生长的云南福贡、碧江、泸水等地区的环境监测,其传感器选型符合当地特殊的环境要求,数据采集及传输方式合理有效,可以实现室外条件下多个环境因子的共同监测和无线传输。

[Objective]The present research was conducted to understand the real-time environmental parameters of Paphiopedilum armeniacum and to master its optimal living environment in order to provide references for further environmental parameters control,species growth promotion and propagation,species extinction prevention,and ecological environment protection.[Method]Using AT89C51 as the microcontroller,parameters such as temperature,humidity,and light intensity of the living environment were monitored and the data were collected by DS18B20 temperature sensor,HS1101 humidity sensor,TSL235 light-frequency converter,respectively,and then the data were wirelessly transmitted by PTR2000 module.[Result]AT89C51 singlechip could jointly monitor temperature,humidity,light intensity,and other environmental factors;the corresponding values of environmental factors were displayed on nixie tube with the transmission distance of 300 meters.[Conclusion]This research design is suitable for monitoring environmental factors of Fugong,Bijiang,and Lushui regions of Yunnan Province,where Paphiopedilum armeniacum are grown.Environmental factors measurements,such as outdoor joint monitoring and wireless transmission,could be understood based on the sensors adaptability to local environment,reasonable data collection,and different transmission modes.
