Automatic Recognition and Detection System Based on Machine Vision
Published 2022-01-01“…This paper combines machine vision with motion control theory and uses pulse coupled neural network (PCNN) edge detection and recognition algorithms to preliminarily design a set of machine vision automatic recognition and detection systems and carry out detection and recognition experiments on small parts such as relay covers. The experimental results show that the whole process of part size detection and recognition, including part feeding, image acquisition, size recognition, part screening, and reset of the experimental platform, can be completed within 5 s and can carry out high-precision dynamic recognition and detection when the part moves at a speed of 1 m/s. …”

Distributed data storage and transmission for space Internet of things
Published 2018-12-01“…Based on the concepts and related techniques of Internet of things (IoT),tracking the development tendency of the satellite IoT and LEO constellation communication system abroad,and the deployment of the integrated satellite-terrestrial information network in China,the concept of space Internet of things (Space IoT) with its framework and main characteristics was proposed.Space IoT has the different concept compared to the traditional IoT,not just using the relay satellite to implement remote machine-to-machine communication.Space IoT is a ubiquitous IoT system under the integrated satellite-terrestrial information network architecture,and an expansion of the terrestrial IoT in the global three-dimensional world,and a service and application platform of multiple information technologies.With the recently era of big data,the space IoT has to face some data storage and transmission problems,such as excessive system load,data loss,frequent link interruption,high energy consumption,etc.Establishing a space-oriented IoT integrated distributed storage and transmission system was to meet the requirements of security guarantee and cross-domain interconnection with massive information businesses.Development status of related technologies were illustrated.At last,the prospect and thought of the future research of space Internet of things were presented.…”

Distributed IOS-SM transmission scheme with joint antenna and IOS unit selection for high-speed railway scenario
Published 2023-04-01“…A distributed intelligent omni-surface (IOS) -assisted spatial modulation (SM) transmission scheme was proposed to address the problem of transmission rate degradation caused by the high signal penetration loss in closed carriages in the high-speed railway scenarios.Firstly, SM technology was utilized to ensure that the indexed information section was not affected by penetration loss.Then, to reduce the high path loss and power loss of the long-range IOS windows, the distributed IOS was selected by traversal algorithm according to the principle of maximizing the received signal-to-noise ratio, and the best IOS window was activated to transmit the SM modulated information.Finally, to reduce the impact of the missing direct view path gain on the overall system performance, the antenna removal principle and the sequential selection method were used to dynamically and selectively activate the receiving antenna and IOS unit under the power consumption model.The simulation results show that the proposed scheme is more suitable for the high-speed railway wireless communication scenario than the conventional relay-forwarding and reconfigurable intelligence surface -SM (RIS-SM) schemes.And with the power loss model, the distributed IOS-SM scheme chosen by the combined antenna and IOS unit is still able to guarantee high performance transmission of the system.…”

Emergence of Prediction by Reinforcement Learning Using a Recurrent Neural Network
Published 2010-01-01“…In a task where an agent gets a reward when it catches a moving object that can possibly become invisible, it was observed that the agent learned to detect the necessary factors of the object velocity before it disappeared, to relay the information among some hidden neurons, and finally to catch the object at an appropriate position and timing, considering the effects of bounces off a wall after the object became invisible.…”
