摘　　要：该文提出一套基于单片机的家居环境监测器的设计方案。以STC89C516单片机作为主控模块,使用霍尔传感器、盖革计数管和甲醛传感器作为数据采集模块,实时获取室内电磁辐射强度、电离辐射剂量率和甲醛浓度的监测数据,并通过GPRS通信模块,将3项监测数据以短信方式向房主手机定时发送。初步测试中,在系统程序指定手机上成功接收到3项监测数据,均值分别为4.61 mT、1.0372 mSv/y和0.0499 mg/m^(3)。测试结果表明,系统总体设计合理、各功能模块运行稳定,实现多参数实时监测的预期目标,可应用于家居环境的监测。Based on Microcontroller Unit technology,a design scheme of Home Environment monitor was proposed.In this system,STC89C516 MCU was used as the main control module.Hall sensor,Geiger counter tube and formaldehyde sensor were used as data acquisition modules to obtain electromagnetic radiation intensity,ionizing radiation dose rate and indoor formaldehyde concentration data in real time.GPRS communication module was used to send the real-time monitoring data to homeowner regularly by mobile short message.In the test experiments,short messages of the monitoring data were successfully received by the designated mobile telephone in the computer program.The average values of electromagnetic radiation intensity,ionizing radiation dose rate and indoor formaldehyde concentration were 4.61 mT,1.0372 mSv/y and 0.0499 mg/m^(3).The test results show that the design schemeis reasonable,operation of each functional module is stable and expected function of real-time multi-parameter monitoring is achieved.This system can be applied to the home environment monitoring.
