Internal combustion locomotive diesel engine system monitoring device

Abstract

The invention provides an internal combustion locomotive diesel engine system monitoring device which is mounted near a diesel engine and is capable of reducing a large amount of long-distance locomotive wire arrangement and lowering the manpower and material costs. The internal combustion locomotive diesel engine system monitoring device comprises a shell, a signal collection plate used for collecting a signal and a main control panel, wherein the signal collection plate and the main control panel are connected inside the device through a flexible flat cable. The internal combustion locomotive diesel engine system monitoring device is mounted near the diesel engine and is capable of reducing a large amount of long-distance locomotive wire arrangement and lowering the manpower and materialcosts; and an information collection part circuit and a control part circuit are isolated digitally, the anti-interference capability of the device is significantly improved, and the influence on other control equipment of a locomotive is reduced.

Description

technical field [0001] The invention relates to the field of microcomputer network control of a diesel locomotive, in particular to a monitoring device for a diesel engine system of a diesel locomotive. Background technique [0002] Diesel engine is the core component of diesel locomotive, which involves many aspects such as driving safety, environmental protection and energy saving of diesel locomotive. The control of diesel engine system is an important part of the whole vehicle control of diesel locomotive. Signals of various specifications and parameters including quantity input signal, frequency quantity signal, and feedback output signal, among which, 24V switch quantity signal includes some switch quantity signals including gear position signal; analog quantity input signal is divided into current type, Voltage type and thermal resistance type, current type input signals include diesel engine oil pressure, oil temperature signals, etc., thermal resistance type input s...

AI Technical Summary

Problems solved by technology

[0003] At present, all kinds of signals in the diesel engine system on the locomotive are wired to the electrical cabinet of the locomotive, collected and processed by the vehicle control device installed in the electrical cabinet, and finally sent to the MVB network of the locomotive. The wiring of the locomotive wiring The quantity is large, the distance is long, and the signal is directly connected to the vehicle controller without isolation, and the anti-interference ability is poor. Due to the complex grounding of the diesel engine system itself, the feedback signal is easy to cause interference to other signals of the locomotive

[0004] The purpose of the present invention is to solve the problems of the diesel engine system control structure in the prior art, such as large amount of wiring, long distance, easy interference of signals and mutual interference between each other, as well as relatively low analysis and diagnosis functions of the diesel engine system, etc. defect problem
