A generating set remote fault diagnosis and health monitor system and a data capture method

Abstract

The invention provides a generating set remote fault diagnosis and health monitor system comprising a generating set data collector module and a cloud server module. The system is connected to a generating set controller and auxiliary electric control equipment around the generating set through the generating set data collector module, acquires various operation data and states of the generating set and data of the peripheral auxiliary electric control equipment, transmits the data and the states to a cloud server module through an Internet to carry out operation data recording, diagnoses reasons of faults, carries out performance analysis calculating on the data which are in accordance with characteristics regularly to obtain performance data and latent fault information of the generating set, and is further connected to a data monitor center and a user terminal through the Internet to realize functions of remote on-line fault diagnosis, latent fault alarm and performance analysis of more than 1000 generating sets so as to raise diagnosis efficiency and accuracy, reduce human cost and evection cost, discover latent faults in advance and maintain the generating set in a healthy state.

Description

technical field [0001] The present invention relates to the field of data acquisition technology for remote online health monitoring and fault diagnosis of generator sets and cloud service diagnosis technology, specifically, to a method for realizing remote data acquisition of generator sets, capturing data, monitoring and The invention relates to a system for controlling and controlling peripheral electric control components of a generating set, and connecting data to the Internet, and a data capturing method. Background technique [0002] Internal combustion engine generator sets are widely used as important backup power sources in communication engineering, fire protection and industrial applications. There will always be various failures during the operation of the unit. How to find out various potential problems in advance to prevent them from being discovered when they need to be used, and how to reproduce the failure scene when a failure occurs during operation, so th...

Problems solved by technology

[0003] The existing genset controller cannot monitor the performance of the genset, which causes the genset to work with illnesses and eventually lead to serious failures

For example: when the load changes, the speed or voltage response of the unit is slow, and the frequency or voltage fluctuates greatly, resulting in severe impact on the load and even affecting safe production

Although the cloud server can receive the collected unit data and perform performance analysis and calculation, but under the existing network speed, especially under the 2G and 3G networks, it is still impossible for one server to simultaneously generate real-time data for hundreds of generator sets Recording, fault diagnosis, performance analysis, discovery of potential faults, etc., because any network instability will affect the transmission of real-time data, and eventually cause the data to be incomplete and cannot be analyzed normally

[0004] In addition, as a remote data acquisition and control device directly connected to the generator set, there are security problems when connected to the Internet, such as: hackers attack by rewriting program codes, etc.

In addition, the existing genset controllers or monitoring systems cannot detect potential faults in advance and have no health monitoring capabilities. These are long-standing problems that have not been well resolved
