电子制冷隧道温湿度控制系统的设计与实现

摘要

针对隧道的潮湿低温环境，设计并实现了基于 STC12C5A32S2单片机的电子制冷温湿度控制系统。系统通过对温湿度数据进行固定时间间隔的突变检测及增加积分环节的措施，保证了数据的稳定性和准确性；反馈控制技术的采用使系统能够在较短时间内将温湿度调控至正常范围。测试结果表明，该系统可满足隧道中恶劣的环境要求，且运行稳定，性能良好。%According to the damp and low temperature environment in tunnel,a electronic refrigeration tem-perature and humidity control system based on STC12C5A32S2 was designed and realized.It detected the temperature and humidity algorithm after a certain time and added integrators to ensure the stability and the accuracy of the data.The feedback control technology was also used to make the controling temperature and humidity to the normal range in short time.Testing results showed that the system could meet the require-ments of harsh environment in the tunnel,and have stable running and good performance.
