Embodiment 1

[0022] A remote on-line diagnosis system for a power plant boiler, comprising: an on-site measurement and control local area network and a remote diagnosis center, the remote diagnosis center including a remote diagnosis center local area network 1, a database server 2, a diagnosis server 3, a Web server 4 and a data storage server 5 are connected to each other through the remote diagnosis center LAN, the diagnosis server is connected to a group of diagnosis modules 6, the data storage server is connected to the central storage disk array 7, and the remote diagnosis center LAN is connected to the on-site measurement and control The data forwarding server 8 of the local area network is connected to the Internet through a firewall and a VPN router;

[0023] The data forwarding server is connected to a database server 9, and the database server is connected to a group of data acquisition servers 10 installed in the unit.

Embodiment 2

[0025] According to the remote online diagnosis system for power plant boilers described in Embodiment 1, the remote diagnosis center adjusts and improves the analysis model on the basis of accumulated operation data and actual on-site operation, forms a module for abnormal diagnosis of equipment failures, and monitors the status of power plant units in real time. And by combining the actual situation of on-site operation and maintenance and expert diagnosis experience, when data abnormalities are found, corresponding operation and maintenance analysis results, suggestions and guidance are given;

[0026] The remote diagnosis center adopts the method of Ethernet based on VPN technology to build, and the structure adopts a three-layer architecture that separates the database server, diagnosis server and Web server. The diagnosis server implements fault diagnosis for remote customers by calling the diagnosis service program. The server is used to store the data collected by the d...

Embodiment 3

[0029] The online diagnosis method of the above-mentioned utility boiler remote online diagnosis system, the steps of the online diagnosis method are as follows:

[0030] 1. The boiler operation data collected on site is transmitted to the remote diagnosis center through the VPN network;

[0031] 2. The remote diagnosis center trains the data samples collected on site through the model to establish a fault diagnosis model;

[0032] 3. The remote diagnosis center performs wavelet transformation on the field signal data, extracts fault features, and inputs the operating data into the online diagnosis system as the input layer;

[0033] 4. The remote diagnosis center analyzes and diagnoses the fault and obtains the diagnosis result;

[0034] 5. Output the diagnosis result generation report to the user.

[0035] The workflow is:

[0036]The remote online diagnosis system for power plant boilers is composed of on-site measurement and control LAN and remote diagnosis center. The...
