摘要:

有效、快速地评价猪肉新鲜度对猪肉品质监测具有重要意义。然而,传统的感官评价方法过于主观,理化分析又耗时过长且具有破坏性。虽然射频信号被用于定位、材料识别、生命体征监测,但在肉类新鲜度检测方面并未受到重视。提出了一种实时、无损、低成本的基于信道状态信息(CSI, channel state information)的猪肉新鲜度检测系统Wi-freshness。该系统基于泛在网络(商用Wi-Fi)部署和实施,是物联网在生鲜农产品领域一个新的应用。Wi-freshness包括CSI数据感知、数据预处理、检测建模和新鲜度检测4个模块。考虑Wi-freshness需要处理的数据特征值不多,以及对预测的实时性要求较高的特点,提出一种基于宽度学习系统(BLS, broad learning system)的检测模型。实验结果表明,Wi-freshness系统能达到93%以上的检测准确率。

Abstract:

Effective and rapid detection of pork freshness is important for pork quality.However, traditional sensory evaluation methods are too subjective, physical and chemical analysis methods are time-consuming and destructive.Recently, radio frequency is widely used in the field of location, material identification and human body monitoring, while, the meat freshness detection is ignored.A real-time, non-destructive and low-cost system for pork freshness detecting based on channel state information (CSI) was proposed.It is a new application of internet of things in the field of fresh agricultural products based on ubiquitous network (commercial Wi-Fi).The proposed Wi-freshness consists of four modules: CSI data sensing, data pre-processing, detection modelling and freshness detection.Considering the need for Wi-freshness data characteristic value processing is not much, and high demand for real-time prediction characteristics, a detection model based broad learning system (BLS) was proposed.Experiment shows that Wi-freshness system can achieve more than 93% detection accuracy.

Key words: channel state information, Wi-Fi, pork freshness detection, broad learning system
