摘　　要：当前智能监测系统由于尺寸较大,导致生产成本过高,且安装维护非常复杂。为此,针对大型物联网设备,设计一种智能嵌入式监测系统。给出系统的总体结构,将S3C2440处理器作为核心控制器,依据传感器采集的监测数据对大型物联网设备进行异常检测,当传感器向处理器传输的数据值高于报警阈值时,处理器将利用LCD液晶屏对结果进行显示,发出蜂鸣报警,把高于阈值的数据保存至嵌入式数据库中。详细介绍S3C2440处理器、RS 232串口、蜂鸣器、SD卡、NAND FLASH存储器和传感器的硬件结构。软件设计时,给出系统的程序开发流程和建立Qt/Embedded项目文件的详细代码。实验结果表明,所设计系统不仅监测精度高,且实时性强,整体性能优越。The current intelligent monitoring system has high production cost, and complicated installation and mainte- nance due to its large size, therefore, an intelligent embedded monitoring system was designed for large-scale IOT equipments. The overall structure of the system is given. The S3C2440 processor is taken as the core controller of the system to perform the anomaly detection of the large-scale lOT equipment according to the monitoring data acquired by the sensor. When the data value t transmitted by sensor to the processor is higher than the alarm threshold, the processor will display the result by means of LCD screen, give a buzzing alarm, and save the data higher than the threshold into the embedded database. The hardware structures of $3C2440 processor, RS 232 serial port, buzzer, SD card, Nand Flash memory and sensor are introduced in detail. The pro- gram development process of the system is given and the detail code of the Qt/Embedded project file is established in software design. The experimental results show that the system has high monitoring precision, good real-time performance and superior overall performance.
