Sensor networking time-staggered awakening control method and system based on ZigBee technology

Abstract

The invention discloses a sensor networking time-staggered awakening control method and system based on a ZigBee technology. The method comprises the steps: enabling a sensor to collect a vibration signal and an instantaneous temperature of a vibration measurement point, obtaining a vibration state value of the vibration measurement point through edge calculation, and uploading the vibration statevalue to an industrial IOT box; collecting acceleration original value data via the sensor according to a command of the industrial Internet of Things box and uploads the acceleration original valuedata to the industrial Internet of Things box; controlling the sensor to wake up in a staggered manner, acquiring an acceleration original waveform of the vibration measurement point, storing the acceleration original waveform in a local flash memory, and waiting for a command of the industrial Internet of Things box to export data to the industrial Internet of Things box. According to the methoddisclosed in the invention, hundreds of vibration measurement points are comprehensively managed by the public industrial Internet of Things box; hundreds of infrared temperature measurement and vibration sensors are sequentially awakened in a time-staggered awakening mode, the vibration condition waveform of the current vibration measurement point is collected, parameters such as the dormancy time, the vibration automatic awakening function enabling and the collection wavelength of the infrared temperature measurement and vibration sensors can be configured, and the method is effective and reliable.

Description

technical field [0001] The invention relates to the technical field of monitoring sensors, in particular to a ZigBee technology-based sensor network wake-up control method and system at staggered times. Background technique [0002] At present, most of the vibration monitoring systems on steel rolling motors use wired vibration sensors, which are expensive and cumbersome in wiring. Most motors cannot be monitored, affecting production efficiency. Therefore, a wireless vibration sensor is needed to monitor the vibration of the rolling motor. Most of the wireless vibration sensors currently used in the long-distance range can only transmit the vibration state value of dozens of bytes, and cannot realize the transmission of the original vibration waveform with a large amount of data. It is even more difficult to monitor hundreds of vibration measurement points on the machine and collect the original vibration waveform with a large amount of data. [0003] As a low-speed, low...
