毕业设计(论文) 基于SPCE061A的环境测试仪的设计与实现 摘 要 环境测试仪是人们生活中经常用到的电子测量仪，本文对基于SPCE061A的环境测试仪的设计与实现进行了详细的研究。环境测试仪主要用于环境温度测量和光线强度测试，借以发现温度与光线强弱是否符合我们的生理需要。虽然现今市面上有很多环境测试仪，但针对人们学习生活需要的环境测试仪却很少，尤其是光线强度的测量，因此设计出可见光范围内的光线测试仪十分必要。 本设计以凌阳SPCE061A单片机作为控制平台，以红外线作为传输介质。系统采用热敏电阻作为温度传感器，光敏电阻作为光线传感器，实现环境温度值和光线强度值的测量，测试结果表明了环境温度高低和光线状态，并由语音播报以提醒人们保护眼睛。该环境测试仪在视距范围内可以独立灵活使用，而不受物理位置影响。本测试仪在测量时，系统进行十次测量，再取平均值，大大提高了测量精度。最后，通过对硬件和软件的调试，系统达到了本设计的要求。 关键词 SPCE061A；温度测量；光线测量；传感器 Abstract Environmental testing for peoples lives is often used in the electronic measuring instrument, the paper-based environment SPCE061A instrument design and implementation of a detailed study. Environmental testing is mainly used for measuring ambient temperature and light intensity test to find temperature and light intensity is in accordance with our physiological needs. Although many of todays market environment tester, but for people to study the needs for environmental testing are few, especially light intensity measurement, designed within the framework of the visible light tester is very necessary. The design Sunplus SPCE061A SCM is a control platform to the infrared as a transmission medium. The system uses the thermistor to take the temperature sensor, photosensitive resistance takes the optical fiber sensor, to achieve environmental temperature and light intensity of the measurement, test results showed that the ambient temperature and lighting levels, and by the voice broadcast to remind people of eye protection. The test environment within the framework of flexibility in the use of independent, free from the physical location of impact in-the-horizon. The test instrument in the measurement, the measurement system is takes 10 times the average, greatly improving the measurement accuracy. Finally, the hardware and software debugging, the system reached the design requirements.
