摘要
设计了以AT89C52单片机为核心的温室环境多参数自动监测仪。采用传感器HIH-3610,DS18B20,TSL2561以及AM-4模块对多个环境参数检测,通过TLC1549模数转换器或I2C总线与单片机接口相连;实现了温室环境多参数动态采集与显示、数据USB存储、参数在线修改和4～20mA远程传输等功能。现场运行表明:监测仪运行可靠,检测精度高,数据传输实时性好,具有很好的实用价值。
Automatic monitor for greenhouse environment multi - parameters was designed and the single chip microcomputer was AT89C52. In this monitor, sensors of HIH -3160, DS18B20 ,TSL2561and AM -4 modular could detect several green -house environment parameters. The interface was TLC15949 digital -analog converter or I2C bus between sensors and MCU. This monitor had realized many functions such as dynamical multi - parameters collection and display, USB data storage, parameters on -line modification and 4 -20mA signal remote transmission. The field operation shows that： the monitor has reliable operation, high measuring accuracy, good real -time performance and practical value.
