摘要
针对传统输电线路机械式风速风向采集系统的不足,设计了一种以ARM为核心的风速风向采集仪。该系统采用STM32处理器,以超声波时差法为测试手段,同时采用温度补偿技术,地磁角校正技术以及GPS定位技术,实现了输电线路风速风向的准确监测,并通过GPRS实时发送数据至主控室。该系统具有免维护、功耗低、精度高、安装方便等优点,可广泛用在输电线路监测环境中。
To overcome shortcomings of traditional mechanical anemometer wind acquisition system of power transmission line, the ARM wind collect instrument was designed.The system used STM32 as processor,ultrasonic-time-difference testing method and temperature compensation technology, geomagnetic angle correcting and GPS positioning technology realizing accurate test of wind speed and wind direction of transmission line, and the collected data can be real-time transmitted to the main control room.The system is free-maintenance, and has low power consumption, high precision, and convenient installation, which can be widely used in power transmission line monitoring environment.
