基于树莓派的无人值守信息处理系统

Unattended information processing system based on Raspberry Pi

摘要:

国内畜牧业智能化程度不高,相关环境监测系统依赖进口。针对这种情况,结合树莓派和多传感器设计并实现了一种无人值守信息处理系统,采用温度,湿度,图像和声音等传感器阵列,通过树莓派wiringPi驱动库进行驱动,实现对猪场的复杂环境进行实时监测。程序设计中采用多进程技术使各模块协同工作,保证了系统稳定高效运行。图像处理算法基于Open Source Computer Vision Library(OpenCV)设计,通过对图像中目标物的特征进行扫描,从而判断目标物状态。系统数据经处理后,通过树莓派板载的WIFI传输到上位机,便于生成数据日志。整个测试系统搭载在一个移动平台上,能够实现移动监测。本系统经过测试,系统稳定运行,温湿度数据测量精度可达0.1,系统能够对危险情况及时响应。

Abstract:

The intelligent degree of domestic animal husbandry is not high and the related environmental monitoring system depends on the import. In response to this situation, an unattended information processing system was designed and implemented based on Raspberry Pi and multisensor. The platform used temperature, humidity, image and voice sensors array which were driven by raspberry wiringPi drive library to realize the real-time monitoring on the complex environment of pig farm. In the program design, multi process technology is used to make the modules work together to ensure the stable and efficient operation of the system. The image processing algorithm is designed based on Open Source Computer Vision Library (OpenCV) and the target state is judged by scanning the characteristics of objects in images. Measured data were processed and transmitted to PC through the Raspberry Pi WIFI to built the log file. The driver of the hardware was realized by using the wiringPi integrated library. The whole test system was carried on a mobile platform to realize mobile monitoring. In system testing, the system runs steadily, the measurement accuracy of temperature and humidity data is up to 0.1, and the system can respond to the dangerous situation in time.
