Digital vibration signal intelligent transmitter

Abstract

The invention provides a digital vibration signal intelligent transmitter, and relates to the technical field of rotary machinery. The digital vibration signal intelligent transmitter comprises a vibration sensor used for collecting and outputting vibration signals generated by a tested device; and a transmitter body connected with the vibration sensor through a transmission line and remotely connected with a data analysis center, wherein the transmitter body comprises a receiving module used for receiving the vibration signals collected by the vibration sensor; a processing module used for processing the vibration signals to parameterize the vibration signals and outputting a parameterization result; a communication module connected with the processing module and used for sending the parameterization result to the data analysis center for further trend analysis; and a power supply module used for supplying power to the receiving module, the processing module and the communication module. The method effectively reduces the amount of transmitted data, so that network bandwidth cost and cloud data storage cost of the data analysis center are effectively reduced, and a data productionsolution is provided for long-term trend analysis of time domain parameters of the vibration signals.

Description

technical field [0001] The invention relates to the technical field of rotating machinery, in particular to a digital vibration signal intelligent transmitter. Background technique [0002] With the continuous development of modern industry and science and technology, as basic equipment widely used in various fields of the national economy, rotating machinery and equipment are widely used as key equipment in electric power, petrochemical, aviation and other fields. Due to its complex structure and long-term operation under harsh conditions such as high temperature, high speed and fluid-structure coupling, abnormally large vibrations often occur due to parts failure, long-term wear and other reasons, and continue to operate without human intervention. , which will soon lead to serious failure of rotating machinery and equipment to shutdown, resulting in major economic losses and even safety accidents. Therefore, it is very necessary to carry out continuous online monitoring ...
