存储式交通气象传感器数据采集系统

Stored Traffic Weather Sensor Data Acquisition System

针对交通气象监测等领域对数据采集系统数据安全性与低成本的要求,设计一种基于存储式的气象数据采集系统,系统利用RS485自动收发电路采集前端气象传感器输出的气象监测区域采集时间、能见度、风速、风向、降水、气压、温度、相对湿度等数据信号;以STM32F103主控芯片进行数据处理,通过FatFS文件系统移植、SPI通信实现数据存储,提升对低信号区域气象灾害的监测和预警能力。试验结果表明,此系统能实时采集、解析、存储气象传感器数据,具有数据存储量大、兼容性强、成本低、稳定性高的优势,便于对交通气象传感器进行长期采集、存储、分析。

Aiming at the requirements of data security and low cost of data acquisition system in the field of transportation meteorological monitoring and other fields,a storage-based meteorological data acquisition system is designed,and the system utilizes RS485 automatic transceiver circuits to collect data signals such as time of meteorological monitoring area collection,visibility,wind speed,wind direction,precipitation,barometric pressure,temperature,relative humidity and so on from the outputs of front-end meteorological sensors;and the data processing is carried out with the STM32F103 master control chip.The STM32F103 main control chip is used for data processing,and data storage is realized through FatFS file system transplantation and SPI communication to enhance the monitoring and early warning capability of meteorological disasters in low-signal areas.The test results show that this system can collect,parse and store the weather sensor data in real time,with the advantages of large data storage,strong compatibility,low cost and high stability,which is convenient for the long-term collection,storage and analysis of the traffic weather sensor.
