Abstract
The utility model discloses a locomotive operation information display device which adopts an ARM chip as a processor. As the ARM chip has high stability and is not easy to be affected by environmental factors, the locomotive operation information display device has high stability.
Description
Technical field
The utility model relates to the locomotive technology field, particularly relates to a kind of locomotive operation information display device.
Background technology
The driver is driving railway locomotive (abbreviation: locomotive), often need by the operation information of devices such as instrument with reference to locomotive.
The information that traditional mechanical type instrument can provide seldom, and is nor directly perceived, can not well be known by the driver.So the intelligent display unit just occurred, at present the intelligent display unit that uses of locomotive industry mainly contains following two kinds: based on the display terminal of digital signal processing DSP and complex programmable logic device (CPLD) (display driver) with based on the display terminal of the Industrial PC Computer of the X86 of Intel framework.
Though it is more or less freely that these two kinds of display terminals are developed, vibrated easily, the influence of dust, humidity, high temperature and other environmental problems, and situations such as the power consumption quantitative change is big, fluctuation of service, loss of data occurred.So locomotive needs a stable high locomotive information display device that is not subject to environmental influence.
