Diesel engine running condition detection method and system

Abstract

The invention provides a diesel engine running condition detection method and system. The method includes: acquiring and recording running status of working conditions of working systems of a diesel engine, wherein the running data includes discrete data and continuous data; adding the running status into running status data lists of the working systems corresponding to the running data; displaying the running status data lists of the working systems of the diesel engine in a preset mode; judging whether the diesel engine is broken down or not according to the running data, if yes, performingfault diagnosis analysis according to the running data within the preset period before and after the fault time, and generating a fault diagnosis report according to the analysis result. By the arrangement, sufficient data support is provided for fault analysis of the diesel engine, the running data belonging to the same working systems is added to the same running status data lists, the running status acquired is no longer isolated, and the fault of the diesel engine is rapidly positioned and diagnosed.

Description

technical field [0001] The invention relates to the technical field of fault detection, in particular to a method and system for detecting the running state of a diesel engine. Background technique [0002] With more and more types and quantities of electrical equipment, among these electrical equipment, there are not only fire-fighting equipment such as fire pumps and sprinkler pumps, but also electrical equipment such as domestic pumps and elevators that require reliable power supply. The reliability of the power consumption of these equipment, when the municipal power grid cannot provide reliable power supply, the emergency diesel generator set is usually used as the backup power supply for the above-mentioned equipment in the design. [0003] In the prior art, the emergency diesel engine event recorder device is usually used to record the operating status of the emergency diesel engine, and the recorded data only includes the line-type data during the operation of the di...

AI Technical Summary

Problems solved by technology

At present, the emergency diesel engine event recorder device cannot record the working state of the throttle lever

During the start-up of the diesel engine, once the throttle lever appears due to the lack of remote recording signal in the design, once the body governor jams or the stroke deviates during the start-up of the diesel engine test, it will not be possible to locate the fault

For another example, the electronic governor on the diesel engine body sends a continuous 0-1A DC current adjustment signal to the throttle lever actuator. The existing emergency diesel engine event recorder device cannot detect this adjustment signal. If the engine is abnormal, the diesel engine will work abnormally, and it is difficult to locate the fault

[0005] Further, since a large amount of data in the emergency diesel engine event recorder device is isolated from each other, an effective data link cannot be formed, and only under the subjective judgment of an engineer with rich on-site debugging experience, can the data be extracted from the huge amount of waveform data. Very small amount of fault information, huge workload, time-consuming and labor-intensive, low efficiency
