Abstract

The invention provides a flue-external wall temperature difference energy collecting device. The energy collecting device comprises a heat collecting plate, a flue-side circuit board, a bidirectionalporous brick, a perforated insulating layer and an external-wall-side circuit board which are sequentially arranged from the wall of a cement thin-wall discharge flue to an insulating external wall; P-type cement-based Seebeck effect bars and N-type cement-based Seebeck effect bars are arranged in the bidirectional porous brick and the perforated insulating layer. The flue-external wall temperature difference energy collecting device can conveniently and lastingly supply power to wireless sensor networks in an environment-friendly way.

Description

technical field [0001] The invention relates to an energy collection device in an intelligent building, in particular to a device for collecting energy by using the temperature difference between the flue and the outer wall of an intelligent civil building, which is used for powering a wireless sensor node of an intelligent building with low power consumption. Background technique [0002] In the future, a large number of sensor nodes will be distributed in smart buildings, such as indoor and outdoor temperature, humidity, illuminance, wind speed, and wind direction sensors. They all need to solve the problem of node power supply. There are usually two options. First, wiring to achieve power supply and transmission of measurement signals. Consider When it comes to the large number of sensors, the huge volume of the enclosure structure and the possible moving parts, the wiring design and construction costs are relatively high; second, the battery is powered, and the measuremen...
