Abstract

The invention discloses a power management method of a vibration monitoring system based on an acceleration switch. The normally-open type acceleration switch having definite threshold acceleration is selected to be used for being connected with a power supply and a load of the vibration monitoring system, the acceleration switch monitors environment acceleration, when the environment acceleration is equal to or greater than the threshold acceleration of the switch, the acceleration switch is switched off, the load is connected with the power supply, and the vibration monitoring system enters a work state; and when the environment acceleration is less than the threshold acceleration of the switch, the acceleration switch is switched on, the load and the power supply are disconnected, and the vibration monitoring system keeps an outage state and enters a next monitoring period. According to the vibration monitoring system, the acceleration switch is utilized to achieve dynamic power management of event driving, structural complexity of the system is reduced, and system power consumption is reduced.

Description

technical field [0001] The invention relates to a power management method, in particular to a power management method for a vibration monitoring system based on an acceleration switch. Background technique [0002] Vibration is a common phenomenon in nature and engineering. Tracking and monitoring environmental vibration information is of great significance for geological disaster prediction, building health assessment, and equipment fault diagnosis. Due to the wide area and complexity of the application environment of the vibration monitoring system, it is difficult to replace the system power supply frequently. Therefore, an efficient and reasonable power management method is the key to prolonging the service life of the system. [0003] At present, dynamic power management technology is a research hotspot in power management. The basic idea of ​​this technology is to control the system to switch to different energy consumption states in a timely manner through different m...
