Abstract

The utility model provides a sensor energy supplied device for structure is monitored for a long time belongs to civil structure monitoring field. The utility model discloses the device utilizes parts such as solar panel, piezoelectricity pole, permanent magnet to come power supply unit, includes based on photovoltaic power supply principle, piezoelectricity power supply principle, electromagnetic induction power supply principle that the wind power generation principle is with solar energy, wind energy, the collection of environmental vibration equal energy form and storage to the energy that is suitable for various external natural environment is collected, has guaranteed sufficient electric energy deposit, reaches the purpose of lasting power supply, is favorable to building structure's long -term monitoring. Solar panel is solar energy collection not only, regards as wind power generation's the blade and the lumped mass of piezoelectricity pole rod end again to reduce device occupation space, carry high energy and gather the utilization efficiency.

Description

Technical field [0001] The invention belongs to the field of building structure monitoring, and relates to a device that uses solar energy, wind energy, and vibration mechanical energy to supply energy to sensors. Background technique [0002] In the long-term operation process of civil engineering buildings, under the combined action of various external loads such as wind load, environmental erosion, artificial load, etc., it will cause a certain degree of damage to the building. If these damages are not discovered in time, the accumulated damage will be reduced. The ability of the building to resist external loads, which will affect the safe operation of the building. In order to evaluate the health of the building, it is necessary to conduct health monitoring on the building. [0003] The traditional health monitoring method is to use wired sensors, and use cables to transmit the data information of the sensors to the data receiving base station. However, the cable routing dis...
