Information Coding for Cockpit Human-machine Interface

引用

Chinese Journal of Mechanical Engineering 2011年第4期24卷 707-712页

作者： ZHANG Lei ZHUANG damin WANYAN Xiaoru School of Aeronautic Science and Engineering Beihang University Beijing 100191 China

Pilot needs to process lots of information when operating an aircraft, and reasonable information coding can greatly improve the correct rate and speed of information identification. At present, related researches are mainly performed in the laboratory, and the experiment method for abstract simulation is often used to research single digit information coding. The research results demonstrate a lack of systematization and applicability. The present study is based upon information coding methods of human-machine interface under real time in flight simulators. Subjects are required to perform an aircraft landing and the corresponding experiment task. The correct rate and reaction time are chosen as the performance evaluation indexes, combined with eye movement data. The advantages and disadvantages of different information coding methods are also evaluated and analyzed. The experiment results demonstrate that the effect of color coding on the correct rate of information identification is not significant, but the effect on the speed of information identification is obviously significant. The study demonstrates that on a black background, red, green and yellow are suitable colors for color coding, but blue is not. The position of information on the performance of information identification is also significant. The center of the interface is better than the edge, and the left position is superior to the right. The impact of language and a person＇s mother tongue should also be considered in practical applications. The study shows that the Chinese has a higher correct rate of identification than English. As the experiment research method in the present study is based on flight simulator, the actual utility and application value can be guaranteed. The research results have the ability to offer improvements in ergonomic reference for cockpit human-machine interface design.

An experimental analysis of situation awareness for cockpit display interface evaluation based on flight simulation

引用

Chinese Journal of Aeronautics 2013年第4期26卷 884-889页

作者： Wei Hengyang Zhuang damin Wanyan Xiaoru Wang Qun School of Aeronautic Science and Engineering Beihang University

Aircraft cockpit display interface （CDI） is one of the most important human-machine interfaces for information perceiving. During the process of aircraft design, situation awareness （SA） is frequently considered to improve the design, as the CDI must provide enough SA for the pilot to maintain the flight safety. In order to study the SA in the pilot-aircraft system, a cockpit flight simulation environment is built up, which includes a virtual instrument panel, a flight visual display and the corresponding control system. Based on the simulation environment, a human-in-the-loop experiment is designed to measure the SA by the situation awareness global assessment technique （SAGAT）. Through the experiment, the SA degrees and heart rate （HR） data of the subjects are obtained, and the SA levels under different CDI designs are analyzed. The results show that analyzing the SA can serve as an objective way to evaluate the design of CDI, which could be proved from the consistent HR data. With this method, evaluations of the CDI design are performed in the experimental flight simulation environment, and optimizations could be guided through the analysis.

A model for discrimination and prediction of mental workload of aircraft cockpit display interface

引用

Chinese Journal of Aeronautics 2014年第5期27卷 1070-1077页

作者： Wei Zongmin Zhuang damin Wanyan Xiaoru Liu Chen Zhuang Huan School of Aeronautic Science and Engineering Beihang University

With respect to the ergonomic evaluation and optimization in the mental task design of the aircraft cockpit display interface, the experimental measurement and theoretical modeling of mental workload were carried out under flight simulation task conditions using the performance evaluation, subjective evaluation and physiological measurement methods. The experimental results show that with an increased mental workload, the detection accuracy of flight operation significantly reduced and the reaction time was significantly prolonged; the standard deviation of R-R intervals（SDNN） significantly decreased, while the mean heart rate exhibited little change; the score of NASA_TLX scale significantly increased. On this basis, the indexes sensitive to mental workload were screened, and an integrated model for the discrimination and prediction of mental workload of aircraft cockpit display interface was established based on the Bayesian Fisher discrimination and classification method. The original validation and cross-validation methods were employed to test the accuracy of the results of discrimination and prediction of the integrated model, and the average prediction accuracies determined by these two methods are both higher than 85%. Meanwhile, the integrated model shows a higher accuracy in discrimination and prediction of mental workload compared with single indexes. The model proposed in this paper exhibits a satisfactory coincidence with the measured data and could accurately reflect the variation characteristics of the mental workload of aircraft cockpit display interface, thus providing a basis for the ergonomic evaluation and optimization design of the aircraft cockpit display interface in the future.

CS_2 extraction and FTIR & GC/MS analysis of a Chinese brown coal

引用

Mining Science and Technology 2010年第4期20卷 562-565页

作者： TIAN damin LIU Xiangyun DING Mingjie Department of Chemistry and Chemical Engineering Henan University of Urban Construction Pingdingshan 467044 China School of Chemical Engineering China University of Mining & Technology Xuzhou 221008 China

The abundance of low-rank coals in China, such as bituminous and brown coals, makes studies of their composition and structure of great significance to both coal chemistry research and for efficient utilization of the coal. We describe how a Chinese brown coal was ultrasonically extracted with carbon disulfide （CS2） and the raw and extracted coals were characterized by Fourier Transform Infrared Spectroscopy （FTIR）. The corresponding extract was analyzed with a coupled gas chromatograph mass spectrometer （GC/MS）. The FTIR analysis shows a great abundance of amidocyanogen, carbonyl, aromatic and hetero aromatic rings and single carbon-beteroatom bonds. This suggests the possible occurrence of compounds like alcohols, phenols, amines, esters, carboxylic acids, ethers, aromatics or heteroaromatics. The GC/MS analysis of the CS2 extract detected 62 compounds, among which the non-polar ones were of lower abundance while the polar ones were in higher abundance and were structurally diverse. This demonstrates the compositional and structural complexity of Shengli coal.

New insights into carbon-based and MXene anodes for Na and K-ion storage: A review

Journal of Energy Chemistry 2021年第11期30卷 660-691,I0016页

作者： Zhensheng Hong Hajar Maleki Tim Ludwig Yichao Zhen Michael Wilhelm damin Lee Kwang-Ho Kim Sanjay Mathur Fujian Provincial Key Laboratory of Quantum Manipulation and New Energy Materials College of Physics and EnergyFujian Normal UniversityFuzhou 350117FujianChina Institute of Inorganic Chemistry University of CologneGreinstr.650939 CologneGermany Fujian Provincial Collaborative Innovation Center for Advanced High-Field Superconducting Materials and Engineering Fuzhou 350117FujianChina Global Frontiers of Hybrid Interfacial Materials Pusan National UniversitySouth Korea

Na-ion batteries and K-ion batteries are promising alternatives to vastly used lithium-ion batteries mainly due to the larger natural abundance of sodium and potassium resources. Carbon-based and MXene materials have received increasing attention due to their unique layered structure to accommodate the larger sodium and potassium ions. It’s proposed that ionic size disparity (K^(+): 1.38 Å;Na^(+): 0.97 Å;Li^(+): 0.76 Å) leads to sluggish intercalation and extraction kinetics in larger alkali metal ions (AMIs). Nevertheless, the electrochemical inactivity of sodium intercalation in graphite suggests that different chemical properties of AMs and their interactions with carbon host and electrolytes is crucial for interfacial instability and irreversible capacity loss. Structural modifications by expanding interlayer spacing and defect engineering enable reduced diffusion barriers and enhanced insertion of sodium or potassium, but it blurs the electrochemical performance between battery and capacitor. This review provides insight into 2D carbon materials and their architectures for Na and K-ion batteries through an in-depth analysis of structure–property interdependence and different electrochemical mechanisms supported by both experimental and theoretical data to discuss the promises and challenges of post-lithium batteries. Finally, the perspectives and potential directions regarding material design concepts for 2D carbon-based nanomaterials and MXene phases for metal-ion storage are proposed.
