Locomotive display device with 4G transmission and data recorder functions

Abstract

The invention discloses a locomotive display device with 4G transmission and data recorder functions, which realizes the functions of locomotive information display, recording and wireless remote transmission based on a CAN bus. According to the invention, a PC104 mainboard serves as a main control module, obtains real-time locomotive information through a CAN communication module and performs control output, display and storage according to information changes; a multifunctional power supply module is responsible for supplying power to each module in the device, monitoring the temperature ofan industrial liquid crystal display screen, heating when the temperature is low, receiving an external switching value signal and transmitting the external switching value signal to the PC104 mainboard through RS232; and a 4G / GPS module integrates 4G communication and GPS positioning functions, and can transmit locomotive operation data to a network terminal. The locomotive display device adoptsan embedded windows system, and further designs test programs of the modules in addition to loading application programs, so that there is no need to change software storage media or test software inproduct testing and application stages. The modules are connected by adopting a stack structure of PC104, thereby being conducive to increasing and tailoring functions while ensuring the stability, and having universal applicability.

Description

technical field [0001] The invention relates to the field of locomotives, in particular to a locomotive display device integrating 4G transparent transmission and data recorder functions. Background technique [0002] At present, the biggest difficulty in the troubleshooting of locomotive CAN bus is sporadic faults. This makes it impossible for even the most experienced engineers to accurately determine the source of the problem. For example, a freight locomotive experienced an emergency unloading due to CAN communication abnormality during the 10,000-kilometer journey, but the ground test could not reproduce the fault, and engineers needed to spend a lot of time to find the root of the problem. This sporadic communication anomaly seriously affects the safety of locomotive operation. The potential faults of locomotives in operation cannot be predicted by the driver. If the real-time data of the locomotive can be transmitted to the network terminal, the expert system of the...
