基于北斗通信的河道水质监测系统设计

Design of River Water Quality Monitoring System Based on Beidou Communication

针对当前水污染监测费时费力的问题,为了实现实时在线检测水质信息,提出了一种基于北斗通信的浮标监测系统,该系统包括浮标体数据采集系统和岸基接收站系统。以新型设计的浮标为载体的数据采集系统,采用STM32芯片,通过RS485协议读取传感器数据后发送并保存至SD卡中;同时通过北斗模块将数据发送至岸基,岸基上位机可远程浏览浮标状态数据、水质数据以及位置信息。整个系统采用太阳能供电方式,以此完成从数据采集、数据保存到数据传输、数据处理。经测试,整个系统运行状况良好,可实现水质自动化监测,达到预期设计要求。

In view of the current time-consuming and laborious problem of water pollution monitoring,and realizing real-time online detection of water quality information,a buoy monitoring system based on Beidou communication is proposed,which includes a buoy body data acquisition system and a shore-based receiving station system.The data acquisition system with the newly designed buoy as the carrier adopts the STM32 chip,reads the sensor data through the RS485 protocol,sends it to the SD card,and sends the data to the shore base through the Beidou module.The shore-based host computer can be viewde remotely buoy status data,water quality data,and location information.The entire system uses solar power to complete data collection,data storage,data transmission,and data processing.After testing,the whole system is in good working condition,and the water quality can be automatically monitored to meet the expected design requirements.
