Embodiment 1

[0015] Such as figure 1 ~ As shown in 3, the interior of the locomotive on-board display device is composed of a 5.7” or 8.4” TFT wide-temperature display, an inverter, a 200MCPU module, a 64M hard disk, an intelligent voice module, and an aviation plug for signal input and output. The 20W DC power supply passes through The inverter powers the display, and the rest of the unit is powered by a 60W DC power supply. The aviation plug transmits the signal of the external vehicle equipment to the 200MCPU module. According to the program setting, the CPU module stores the signal of the external vehicle equipment through the 64M hard disk, or displays the signal through the 5.7” or 8.4” TFT wide temperature display. The intelligent voice module is used for prompting vehicle location.

[0016] The signal of the external vehicle equipment is transmitted to the microprocessor through the communication link, and the microprocessor processes the signal. According to the preset program, ...

Embodiment 2

[0022] The microprocessor is a high-speed embedded microprocessor with simplified instructions, low power consumption, and a high-performance display chip. It is equipped with a 10.4” TFT true color screen, which can achieve a display resolution of 800X600 and takes up little space. It is suitable for various mobile working environments .Because the dispatching locomotive is located outdoors all the year round and the ambient temperature changes greatly, in order to ensure the reliability of the work, the display screen is a liquid crystal screen with wide temperature electronic components.

[0023] In order to meet the special temperature requirements of vehicle equipment, industrial-grade wide-temperature electronic components are used. In order to communicate with other signal equipment on the vehicle, a communication link with photoelectric isolation is used to improve the anti-interference ability and system reliability. The communication link can be RS232, RS485 or CAN s...

Abstract

The invention relates to a vehicle display device for locomotive, which consists of a display screen, a storage, a micro processor, a graphics processor, a voice module, a communication link and a sealing framework; the vehicle display device for locomotive used under the conditions of limited space, large environmental temperature change and serious dust erosion has excellent dust-proof, shake-proof and anti-interference performances when being used for scheduling locomotives in railway yard.

Description

technical field [0001] The invention relates to a display device, especially for a locomotive on-board display device under the conditions of limited space, large changes in ambient temperature, serious dust erosion, and vibration of the locomotive body, such as a locomotive on-board display device used for locomotive dispatching in railway marshalling yards . [0002] Background technique [0003] In the railway transportation system, locomotive dispatching work is very busy. The locomotive driver’s cab has a small space and there are many parameters to be observed. There is an urgent need for an intelligent display device with a clear interface and storage of road network graphics information, which can provide functions such as data, graphics, symbols, colors, and voices to replace Monochrome, low-brightness, and simplistic display devices. At the same time, because the train is an outdoor sports vehicle, the ambient temperature changes greatly, the car body has vibrat...
