摘　　要：对当前物联网技术及工业设备数据信息采集方式进行调查和分析。本系统采用滤波理论和算法,将所需采集的模拟信号转换为数字信号。使用STM8L系列单片机结合LoRa无线技术,实现数据低功耗、远距离的传输,同时在终端将数据实时存储到SD卡中,实现数据远程、连续、有序地采集。在数据传输方面设计了一套高效安全的数据传输协议,检测数据传输中的错误,保证通信系统的安全性。该系统有效实现低功耗远程A/D数据采集,通过高效安全的数据传输协议提高系统的可靠性,同时对采集数据进行实时存储,全面提高系统的性能。The paper researches the investigation and analysis of the data collection methods of the Internet of things and industrial equipment. The system uses the theory and algorithm of the filter to convert the analog signal to digital signal. Lowpower-consumption and long-distance transmission is achieved by the use of STM8 L Series MCU combined with LoRa wireless technology,meanwhile in the terminal data is stored to the SD card in real time,and remote,continuous and orderly data collection is further realized. In the aspect of data transmission,a set of efficient and secure data transmission protocol is designed,which can detect the errors in the data transmission and ensure the security of the communication system. The system can effectively realize the remote A/D data acquisition with low power consumption,improve the reliability of the system through the efficient and secure data transmission protocol,store the data in real time,and improve the performance of the system.
