Abstract: In the process of extensive monitoring of artificial fish ponds, the method of manual monitoring shows its shortcomings such as low efficiency, poor real-time performance and limited monitoring range. In view of the requirements of miniature, low cost and real-time of modern fish pond monitoring system, A set of multi-node wireless network monitoring system based on FPGA is constructed, which realizes real-time monitoring of dissolved oxygen content and temperature in different locations in fish ponds, not only enlarges the monitoring range of fish ponds, but also improves the monitoring efficiency greatly compared with traditional artificial monitoring. Firstly, the multi-node wireless network fish pond monitoring system is built by using multiple XBee wireless data transmission modules. Secondly, the embedded system is designed with MicroBlaze as the core, and the parallel data processing mechanism is designed. Multi-sensor data processing and judgment, to ensure the continuous operation of the system; Finally, through the FPGA and fish pond terminal control module communication to complete the real-time adjustment of dissolved oxygen content in the fish pond.
