The present invention relates to a self-powered wireless vibration autonomous alarm system and a method thereof which can monitor the mechanical vibration of an external environment and send an alarm / prompt signal autonomously and wirelessly when a vibration amplitude is greater than a specific preset threshold value, and belong to the sensor technology and internet of things field. An autonomous alarm microsystem of the present invention is composed of a vibration self-sensing energy collector, an energy conversion and storage unit, a control circuit and a wireless emission circuit. The vibration self-sensing energy collector has a driving threshold value, does not generate power when an environment vibration amplitude is less than the threshold value and converts the vibration mechanical energy into the electric energy only when the environment vibration amplitude is greater than the threshold value, a sent out AC is converted into a DC in the energy conversion and storage unit and is stored, and when detecting that the electric energy accumulates to a certain extent, the control circuit controls the wireless emission circuit to be powered on and to emit the alarm / prompt signal to report an event.
Description
technical field [0001] The invention relates to the field of sensor technology and the field of the Internet of Things, in particular to a self-powered wireless vibration autonomous alarm system. Background technique [0002] With the development of energy harvesting technology and low-power electronic technology, a variety of self-powered wireless sensor node schemes have also been proposed internationally. An earlier paradigm is the "smart dust" concept that emerged in 1992. This concept was developed by the University of California, Berkeley in 1999. The project uses a large number of intelligent sensing / computing nodes to form a network, each node is powered by solar energy, and realizes network communication through lasers. Due to the clearance requirement of laser communication and the limitation of solar energy by the weather, the mainstream communication method of the self-powered sensor node solution is radio frequency transmission and reception, and the energy is...
