Method and apparatus for controlling, diagnosing and telecommunication managing locomotive and automobile

Abstract

The invention uses an embedded real time multi-task operation system, a high speed embedded communication processor and massive high capacity memories to ensure the high performance of the VCM for processing the communication and data. The VCM hardware system is a CPU-based embedded type system that comprises a CPU subsystem, a memory subsystem, a MVB communication subsystem, a power subsystem and a communication interface subsystem that provides multi kinds of field bus interfaces. The VCM software system uses a modularization hierarchical architecture, and the said equipment driver layer is the lowest layer of the system software.

Description

Technical field [0001] The present invention belongs to a locomotive / vehicle control method and device, in particular to a communication and process control platform in a multifunctional locomotive / vehicle bus (MVB)-based distributed control system, which can realize the functions of MVB 4 types of equipment, including The locomotive / vehicle control module and structure of the multifunctional locomotive / vehicle bus (MVB). Background technique [0002] The vehicle control module (hereinafter referred to as VCM) is mainly suitable for vehicle and process control, fault diagnosis and communication management of locomotives / vehicles. It can also be applied to process monitoring systems in related fields such as subway trains or automation control systems. Its application environment meets relevant industries. Standards (iron standard TB3021-2001, etc.) stipulate. As the core function module in a fieldbus-based distributed control system, VCM can easily realize the vehicle-level / train...

AI Technical Summary

Problems solved by technology

VCM is mainly used in the vehicle control processing platform based on MVB bus, but there are following deficiencies in the existing vehicle control module (or unit, the same below): ①The control function is single, which is mainly due to the slow processing speed of the CPU and the lack of abundant available Caused by the controls of the control system

②The communication function is limited. On the one hand, the CPU speed is slow, which cannot meet the MVB communication requirements of a smaller communication cycle. On the other hand, the vehicle bus module does not have CAN and Ethernet in the past, which limits its application field

③The processing speed of CPU is low, the general speed is tens of megahertz, and the functions of communication, control and diagnosis cannot be taken into account, which limits its scope of application

④The price is expensive, because the plug-in structure is generally used, and the number and types of components need to be greatly increased

⑤The device is bulky and inconvenient to use and install on site, which greatly limits its scope of use

⑥The ability to diagnose and record faults is limited, mainly due to low speed and small storage space
