Problems solved by technology

[0003] However, if there is a problem with the existing generator set, it needs to be inspected by professional personnel on site to determine the fault; this requires the power station to be equipped with professional maintenance personnel, and the cost is very high; if the power station is not equipped with professional maintenance personnel, you need Sending professional maintenance personnel to the site for inspection does not require high costs and is very inefficient

example 1

[0072] see Figure 5 , which shows an example graph of the combined start-up curve of the start-up failure based on this scheme.

[0073] The figure shows:

[0074] 1) The battery voltage drops normally when starting, indicating that the battery voltage is normal;

[0075] 2) The discharge current of the battery is normal, indicating that the electrical circuit of the starter motor is normal;

[0076] 3) The engine speed is zero, and the fault judgment is: the most common and likely fault is the jamming of the top teeth of the starter motor.

example 2

[0078] see Figure 6 , which shows an example diagram of the combination curve obtained based on this scheme when the engine is started.

[0079] based on Figure 6 From the combination curve when the engine is started, it can be seen that the rise of the engine oil pressure lags behind the increase of the speed by nearly 2 seconds, and the build-up of the engine oil pressure is slow. Frequent starts may cause abnormal wear of the engine. It is recommended to check and repair the oil gear pump or check whether the oil is normal. .

[0080] Finally, it needs to be explained that the above-mentioned method of the present invention, or specific system units, or some units thereof, are pure software architectures, and can be deployed on physical media through program codes, such as hard disks, optical discs, or any electronic devices (such as smart phone, computer-readable storage medium), when the machine loads and executes the program code (such as a smart phone loads and exec...

Abstract

The invention discloses a remote fault diagnosis method. The method comprises the following steps: capturing various running state parameters of generator sets; carrying out real-time and remote transmission of the captured state parameters; and remotely carrying out composite curve analysis and variation tendency analysis on the acquired various state parameters, and determining starting failures, potential running fault risks and starting reliability assessments of the generator sets according to analysis results. The method adopting the scheme has the advantages that remote diagnosis of faults of the generator sets in a power station can be accurately achieved, so that problems in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to the generator set technology, in particular to the fault diagnosis technology of the generator set. Background technique [0002] The internal combustion generator set is a device that converts chemical energy into electrical energy. It is used as a mobile power supply to provide power for field users and mobile equipment (such as ships, etc.), and as an important electrical equipment that cannot be interrupted (such as steelmaking furnaces, surgery, etc.) As a backup power supply for laboratories, nuclear power plants, data centers, fire-fighting facilities, etc.), the stability and reliability of its work and the reliability of starting are very important. It can be seen that as a safety product, once a problem occurs in the generator set, how to quickly diagnose the fault of the generator set is very meaningful. [0003] However, if there are problems with existing generator sets, professional personnel must conduct on-site...
