Description

Vehicle-mounted display UI interface design method based on equipment state information Technical Field The invention belongs to the technical field of UI design, and particularly relates to a vehicle-mounted display UI interface design method based on equipment state information. Background A display interface (UI) is an interface between a person and a system, which refers to a collection of interaction methods performed by a user and some systems, and these systems refer not only to a computer program but also to a specific machine, a device, a complex tool, etc. Interactive design (Interaction Design, abbreviated IXD) is a design area of defining, designing the behavior of an artificial system, focusing on the content and structure of communication between two or more interacting individuals, in order to enable these individuals to cooperate with one another to achieve a certain objective. Interactive design aims to create and establish meaningful relationships between people and products and services, centered on "embedding information technology in the world of matter that is full of social complexity". The systematic design is a comprehensive design method based on system thinking, and focuses on the structure, function, behavior and performance of the whole system, and the system is planned and designed as a whole to realize the optimal performance and benefit of the system. The LCU is a train contactless programmable logic control unit Logic Control Unit, is a set of on-board computer system specially designed for logic control of railway vehicles, adopts computer and network technology, replaces the traditional contact control circuits such as an intermediate relay, a time relay, a bistable relay and the like of a train by using contactless circuits such as an optocoupler, a field effect transistor and the like, and realizes the functions of train logic control, fault diagnosis, comprehensive protection and the like. In the process of developing a device display system, the interface data is often required to be updated in real time according to the logic calculation state information of the built-in software, and operations such as real-time control are performed on the interface elements. The current display devices DMI are mostly fixed display interfaces, display contents are limited by software program codes, the display contents are positioned by dividing the interfaces by codes, the display of the devices is updated according to updated values of the devices, and the same display device needs to display information of different devices from different manufacturers. Taking the display of the equipment of the train programmable logic control unit as an example, the LCU equipment comprises a plurality of IO plug-ins, can acquire a plurality of data, can show the state and state information of plug-in operation states, software versions, ETH, MVB, CAN, 5G channels and the like on the data display, and can also show information of switching value states, equipment line connection states and the like. And the data which can be acquired are currently displayed by relying on a general display DMI. For the man-machine interaction scheme of the current LCU vehicle-mounted equipment, the following defects exist in actual operation: 1) The data display of the LCU is mostly displayed through a display installed on the railway vehicle, is limited by the existing expression mode of the display, cannot completely display the state information which can be acquired, and is not friendly to the interactive mode of customized information display and graphical display data. 2) Because of the limitation of the screen size of the display of the driving platform of the railway vehicle, the traditional screen displays more text content, displays various data through text and color, and has the problem of crowded content and difficult distinguishing; 3) The state of the switching value of the locomotive is various, the interface state and the link relation are displayed in a multi-purpose text form in a general mode, and the operation efficiency is greatly influenced under the condition that the problem points and the equipment state need to be quickly positioned and repaired; 3) The running state of the LCU vehicle-mounted host computer is judged only by virtue of the colors of the characters or the indicator lamps, the fault detection method is single, the problem causes are difficult to accurately locate, and the daily maintenance and the fault detection of equipment are inconvenient.
