Abstract

The invention provides an online boiler expansion monitoring system which comprises a data acquisition conversion module, a data analysis control module and a data storage module. The data acquisitionconversion module is connected with the data analysis control module by EBUS communication; and the data analysis control module is connected with the data storage module by MODBUS communication; Thedata acquisition conversion module comprises an expansion detection indicator and a displacement sensor, and is used to collect the expansion amount of an expansion point and converts the expansion amount to an electric signal. Equipment deformation caused by improper igniting pressurizing or adverse installation and maintenance can be discovered timely, cracks and leakage due to uneven expansionare prevented, monitoring basis is provided for the security of a boiler, labor and material forces are saved, the monitoring expansion condition can be monitored in real time, possible dangers can be pre-judged timely, equipment damage is timely avoided, and the safety of the boiler is improved substantially.

Description

technical field [0001] The invention belongs to the field of boiler monitoring, and in particular relates to an online monitoring system for boiler expansion. Background technique [0002] At present, the research and development work on the online detection of boiler expansion is very active. The existing expansion indicators mainly include the following two types: one is to monitor by setting a three-dimensional expansion indicator on the main parts of the boiler. At present, most of the indicators are mechanical, and it is necessary to manually climb to the installation point to read the parameters. Real-time continuous expansion situation, can not real-time alarm and other problems. The other is a boiler thermal expansion monitoring system based on the acoustic principle. The sound signal is sent out by the sound wave generator, and after being received by the sound wave receiver, the signal is sent to the host computer. After calculation and analysis, it is displayed o...
