为了提高基层农业信息化水平,大大改善对农业设施的监控效率,结合温室温度预测控制算法,实现了以FPGA为处理器的智慧粮仓内环境预警监控系统。该系统通过Verilog HDL硬件描述语言在FPGA内部设计各个功能模块,由FPGA芯片完成对传感器的驱动并建立通信链路,通过存储器操作指令控制传感器读取、转换温度数据,最后利用调整后的温室温度预测算法对任意时刻后的仓内温度进行预测,判断预测值是否超过预设报警值,同时由开发板上的数码管和LED显示实时温度以及预警信号。实验分为白天和夜晚两组,分别验证不同环境下的预测结论。实验结果表明,该系统实现了分辨率为0.062 5℃的温度监控显示,并能够较为精准...

In order to improve the level of basic agricultural informatization and greatly improve the monitoring efficiency of agricultural facilities,combined with the algorithm of greenhouse temperature prediction and control,the intelligent grain bin environment early warning monitoring system is realized.Each function module in FPGA is designed through Verilog HDL.The driver of the sensor and the communication link are accomplished by FPGA chip.The temperature sensor is controlled by memory operation instructions from the chip for reading and convert...
