Abstract：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.
