基于ModBus的远程数据采集器设计
|
摘要
为了满足工业数据采集应用场景的远程监控与处理,设计了一款具有互联网+特性的远程数据采集器.该采集器采用STM32作为主控制器,同时采集处理16路信号数据.各路数据采集通道均采用磁耦隔离保护,保证硬件和数据的安全、稳定.通信电路采用RS485接口和ESP8266无线通信模块,将采集到的数据基于ModBus/TCP协议分别传输至PC上位机和网络云端,进行存储备份和实时监控.该数据采集器经系统测试,具备较高的采集精度和数据稳定性,满足工业现场应用需要.
In order to satisfy the application scenario of industrial data acquisition remote monitoring and processing,a remote data collector with Internet plus initiative features was designed.The data collector is mainly controlled by STM32,16 signals can be collected and processed at the same time.All data acquisition channels are protected by magnetic coupling isolation,Ensure hardware and data security and stability.The communication circuit adopts RS485 interface and ESP8266 wireless communication module to transmit the collected data to PC upper computer and network cloud based on ModBus/TCP protocol respectively for storage backup and real-time monitoring.The system test showed that the data collector had high precision and data stability,meet the requirements of industrial application.
