Problems solved by technology

[0003] At present, most of the on-board monitors on the train adopt the method of classification control and display, that is, display different types of information content through different monitors, which leads to multiple monitors with different styles on the train control console, which affects the driving personnel to a certain extent. The judgment of information may easily lead to misoperation in emergency situations, and at the same time, it requires a high memory of the driver and affects the appearance

Embodiment 1

[0053] figure 1 It shows a schematic structural diagram of a large-screen display device for trains provided by Embodiment 1 of the present invention, refer to figure 1 It can be seen that the device includes:

[0054] Display H, which is composed of multiple sub-displays seamlessly spliced;

[0055] A plurality of display control boards C, which are respectively connected to each sub-display correspondingly, and are used to drive each corresponding sub-display according to a control instruction;

[0056] A plurality of main control boards B, which are correspondingly connected to each display control board C, are used to generate control instructions and send them to the display control board to drive the corresponding sub-display screens;

[0057] Touch screen G, which is seamlessly spliced ​​by multiple sub-touch screens;

[0058] A plurality of touch panels D, which are respectively connected to each sub-touch screen correspondingly, and are used to drive each correspon...

Embodiment 2

[0092] Taking the display screen composed of two sub-display screens as an example, in this embodiment, the display screen is seamlessly spliced ​​by two sub-LCD screens, each screen is controlled by a separate display control board, and the interior of the LCD screen is spliced. Stronger shock resistance. The touch screen is a capacitive touch screen, which is also seamlessly spliced ​​by two touch screens, each of which is controlled by a separate touch panel.

[0093] It should be noted that the large-screen display not only meets the function of simple display, but also needs to communicate with peripherals to obtain information data, mainly to collect the status data of other major electronic products on the train, such as temperature , operation-related parameters, etc., and interact with the driver, that is, the driver can open the corresponding content or control switches by touching or pressing buttons. The structure and main functions that can be satisfied or supporte...

Abstract

The invention provides a large-screen display device for a train, which comprises a display screen formed by splicing a plurality of sub-display screens, a plurality of display control panels correspondingly connected with the sub-display screens, and a plurality of main control panels correspondingly connected with the display control panels, the main control boards generate control instructions and send the control instructions to the display control boards to drive the corresponding sub-display screens, the touch screen is formed by splicing a plurality of sub-touch screens, the touch panels are correspondingly connected with the sub-touch screens, and the expansion board comprises interfaces connected with the main control boards, the display control boards and the touch panels. Data communication between the touchpad and the main control board and data and instruction communication between the device and other modules of the train are achieved. By adopting the device, the problems of complicated display and inconvenience in checking in the prior art can be solved, a console environment is attractive, the data communication with each functional module of a train can be stably and reliably realized, the realization difficulty of design is controlled, and the fund and time for researching and developing targeted hardware are saved.

Description

technical field [0001] The invention relates to the technical field of vehicle displays, in particular to a large-screen display device for trains. Background technique [0002] With the increasing application of rail transit in the field of transportation, in order to realize the precise control of trains, compared with ordinary vehicles or other living facilities, the on-board hardware equipment and on-board data processing facilities of trains undoubtedly need to meet higher requirements. As an important facility on the train, the on-board display device of the train is mainly used to record and display various state information parameters during the operation of the train and the specific information of the required components on the train, and at the same time feed back various related parameters or information to the The driver, in addition, it also serves as a human-machine interface for direct communication with the driver. [0003] At present, most of the on-board ...
