Locomotive touch display system

Abstract

The invention relates to a locomotive touch display system. The system comprises a plurality of touch displays, a communication module and a lower computer, wherein, each of the touch displays comprises a touch screen, a mainboard, a display screen, a backlight inverter unit and a power source, any one of the touch displays can be set as a host and the other computers are set as slaves based on setting, and the host exchanges data with the slaves by a TCP / IP network; the mainboard comprises a central processing unit, a touch control unit, a check and storage unit, a display driving unit, backup batteries and a plurality of outgoing interfaces; the communication module provides communication link between the touch displays and a lower computer, and the lower computer collects the data of various systems of a locomotive by a sensor package, inquires instructions based on the data of the host in the touch displays, transmits response data based on a communication protocol to control the operating logic of the locomotive, and transmits the response data to the touch displays by the communication module to display conditions of the locomotive. The locomotive touch display system meets the use needs of the current railway locomotives and user operation habits, is convenient for use and maintenance, and is applicable to the use of DF7-type locomotives.

Description

technical field [0001] The invention relates to a display device for a locomotive, in particular to a touch display system for a locomotive. Background technique [0002] At present, with the improvement of domestic and foreign users' requirements for the overall performance of locomotives, the existing display devices can no longer meet the requirements of the locomotive market for small batches, diversification, and intelligent products. The display devices of domestic railway locomotives are mostly man-machine interfaces suitable for use in single cabs and have function keys. The hardware is mostly based on the X86 motherboard, and the communication and display programs are developed in C language under the DOS operating system. The existing display technology mainly has the following deficiencies: 1. The program is huge and difficult to debug and change; 2. There is no function such as diagnosis prompts in the state of locomotive failure and it cannot provide timely help...
