Wi-freshness: research on CSI-based pork freshness detecting system by Chao NIU, Weidong YANG, Pengming HU, Xiangshang GAO, Erbo SHEN

“…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.…”

Design and Simulation of Cam Pressurized CVT by Hao Jianjun, Liu Yunyun, Lan Jiashui, Xiong Feng

“…Aiming at the problems of the current CVT actuated by hydraulic control system,such as high energy consumption,complicated control systems,speed ratio and transmission ability being limited by metal belt axial deflection,a new designed cam pressurized CVT hydraulic system is proposed,which is composed of cam automatic pressurized device and closed hydraulic system.The cam pressurized device automatically provides most of the clamping force,the closed hydraulic control system provides the auxiliary clamping force and changes the speed ratio.The new designed hydraulic control system with simple-structure can leave out expensive reversing values and reduce overflow loss,therefore it has advantages of less component parts,energy conservation,environmental protection and low cost.The structure design and working principle of the CVT system are introduced,and the simulation analysis is carried out by using the Matlab/Simulink software.The simulation results show that the cam pressurized CVT hydraulic control system has the significant advantages of fast dynamic response,stable performance and so on.…”
