面向夜间任务的货轮驾驶舱光环境评估

During night driving, the light source in the cockpit comes from electronic screens, and the brightness has a direct impact on the driver's visual ergonomics. Based on the characteristics of the cargo ship cockpit light environment during night driving, the performance of participants under different screen brightness is analyzed through dark environment experiments. From the perspective of task effectiveness, the light environment of the cargo ship cockpit is evaluated based on three dimensions of cognitive efficiency, dark adaptability, and comfort. The experimental data is fitted to construct a light environment evaluation model of the cargo ship cockpit for night tasks. And it is concluded that the task performed well when the screen brightness value is controlled at 20 cd / m² . It plays a guiding role in the optimization of the light environment of the cockpit during cargo ship night driving.
