The data analysis device includes: a first communication module adapted to communicate according to a first communication protocol; The second communication module of protocol communication; The communication control module is adapted to broadcast communication connection establishment instructions through the first communication module; Receive vibration data through the second communication module; Broadcast communication connection disconnection instructions through the first communication module; Each vibration sensor It includes: a first communication module adapted to communicate according to a first communication protocol; a second communication module adapted to communicate according to a second communication protocol; a communication control module adapted to establish a connection with a data analysis device through the second communication module; through the second communication module The second communication module sends the vibration data to the data analysis device; the connection with the data analysis device is disconnected through the second communication module. The invention also 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
