摘要
针对人们在生活中对温湿度的测量系统提出的新要求,如较快的响应速度、高精度、高度集成等功能,为了满足现代用户对温湿度检测的功能和性能需求,提出了一种基于STM32和CAN总线协议的温湿度检测系统。该系统通过CAN总线,实现数据在各个系统中实时高效的传输。最后对整个系统精度进行实验验证,其温度测量精度达到±0.3℃,湿度精度±2%RH。实验结果表明,该系统具有精度高、性能稳定等特性,能快速高效地将当前环境的温湿度值反馈给用户。
For people in the life of the measurement system of temperature and humidity of the new requirements,such as rapid response speed,high precision,high integration and so on.In order to meet the needs of the modern user's function and performance requirements,a temperature and humidity detection system based on STM32 and CAN bus protocol is proposed.The system realizes real-time and efficient transmission of data through CAN bus.Finally,the accuracy of the whole system is tested,the accuracy of the temperature reaches±0.3℃,and humidity reaches±2%RH.The test results show that the system has high accuracy and stable performance and it also can be quickly and efficiently.
