Vibration data analysis system and data transmission method thereof

Abstract

The invention discloses a vibration data analysis system. The vibration data analysis system comprises data analysis equipment and at least one set of vibration sensors associated with the data analysis equipment. The data analysis equipment comprises a first communication module suitable for conducting communication according to a first communication protocol, a second communication module suitable for conducting communication according to a second communication protocol, and a communication control module suitable for broadcasting a communication establishment instruction through the first communication module, receiving vibration data through the second communication module and broadcasting a communication interruption instruction through the first communication module. Each vibration sensor comprises a first communication module suitable for conducting communication according to a first communication protocol, a second communication module suitable for conducting communication according to a second communication protocol, and a communication control module suitable for establishing connection with the data analysis equipment through the second communication module, sending vibration data to the data analysis equipment through the second communication module and interrupting connection with the data analysis equipment through the second communication module. The invention further discloses a data transmission method of the vibration data analysis system.

Description

technical field [0001] The invention relates to the field of data acquisition, in particular to a vibration data analysis system and a data transmission method thereof. Background technique [0002] At present, data analysis equipment on the market generally adopts a wired method to interconnect with vibration sensors. This method has three main disadvantages: (1) The industrial site environment is harsh, the installation environment is complicated, and wiring is difficult; (2) The number of channels is limited. The wired method needs to provide a physical interface for each vibration sensor, but due to the size limitation of the equipment, it is difficult to provide enough external interfaces; (3) Wiring distance limitation. For large equipment, the length of the cable directly limits the distribution range of the measuring points. [0003] Due to the inherent defects of wired communication, the market demand for wireless networking gradually emerged. However, conventiona...

[0002] At present, data analysis equipment on the market generally adopts a wired method to interconnect with vibration sensors. This method has three main disadvantages: (1) The industrial site environment is harsh, the installation environment is complicated, and wiring is difficult; (2) The number of channels is limited.

However, conventional wireless communication methods will also face the problems of low communication rate and poor real-time performance. Therefore, a new communication scheme between data analysis equipment and vibration sensors is needed to make up for the inherent defects of wired networking and ensure wireless networking. Offline high-speed data transmission and good real-time performance
