Problems solved by technology

Because the locomotive has many types of data to be displayed, the traditional display device makes it difficult for the locomotive driver to quickly find the required data; For all data, assuming that the baud rate of the transmission is 9600bit / s, it will take 0.4 seconds even if there is no delay, but if the delay of 2 microseconds is added for each bit transmission, then the time to transmit all the data will exceed 1 seconds
This has a large data delay in program design and cannot meet the requirements

Embodiment Construction

[0010] Now in conjunction with accompanying drawing, the present invention will be further described:

[0011] Such as figure 1 As shown, a display unit of an electric locomotive consists of five parts: the on-site information processing unit 1 in the network control system TCMS is responsible for the acquisition and output of the locomotive I / O quantity, and then transmits the collected data to the vehicle through the locomotive communication bus The microcomputer 2, the vehicle-mounted microcomputer processes the data through the RS485 communication interface 3, and transmits the data to the locomotive display processing unit 12 according to the RTU communication protocol; the 110V power supply module 4 is used to convert the 110V DC power supply for the locomotive into a stable and reliable display unit. required power supply; resistive touch screen 11, used for touch-type man-machine dialogue; man-machine interface display (LCD) 7, used for locomotive operation monitoring,...

Abstract

The present invention discloses an electric locomotive driver display unit. The unit comprises a RS485 communication interface (3), a 110 V power supply module (4), a locomotive displaying and processing unit (12), a resistance type touch screen (11) and a locomotive displaying unit man-machine interface (7), wherein the displaying contents of the locomotive displaying unit man-machine interface (LCD) (7) comprise: a locomotive running interface set (5), a locomotive maintenance interface set (9), a failure diagnosis and alarm (6), a test interface (9) and program update and failure download (8). According to the present invention, the labVIEW programming is adopted on the embedded XPE operating system, the split screen and classification display is adopted, such that the locomotive driver can find the required data by the rapid browse manner; the split screen request of data transmission is adopted, only the data requested by the current screen is transmitted, the amount of the data is less, the data delay is less, the driving requirements of the locomotive driver can be met.

Description

technical field [0001] The invention relates to a display device for an electric locomotive, in particular to a display unit for an electric locomotive driver. Background technique [0002] The electric locomotive driver display unit is a key component in the electric locomotive network control system TCMS, an important platform for the driver to monitor and control the locomotive, and an important tool for locomotive maintenance and testing. Because the locomotive has many types of data to be displayed, the traditional display device makes it difficult for the locomotive driver to quickly find the required data; For all data, assuming that the baud rate of the transmission is 9600bit / s, it will take 0.4 seconds even if there is no delay, but if the delay of 2 microseconds is added for each bit transmission, then the time to transmit all the data will exceed 1 seconds. This has a large data delay in program design and cannot meet the requirements. Contents of the inventi...
