Description
Technical field
The utility model relates to the energy collecting devices in intelligent building, build more particularly, to using a kind of smart utility
Flue-interior temperature difference carries out the device of collection of energy, for the intelligent building wireless sensor node power supply for low-power consumption.
Background technique
A large amount of sensor nodes, such as the temperature of indoor and outdoor, humidity, illumination, wind speed, wind direction are distributed in the following intelligent building
Sensor, be both needed to solve node powerup issue, usually there are two types of selection, first, wiring realize power supply and measuring signal biography
It passs, it is contemplated that number of sensors is various, the building enclosure scale of construction is huge and movable part that may be present, wires design and construction generation
Valence is larger；Second, battery power supply, measuring signal wireless transmission, i.e. building wireless sensor network, kind of method wiring is tired before avoiding
Disturb, but there are still certain negative effects: a) battery capacity is limited, limits node service life, b) node often do not recycle, chemistry
Secondary pollution caused by battery.

The Carbon Fiber Cement-based Composites of cement-base composite material and N-type semiconductor property, solidification are respectively formed p-type cement base
Seebeck effect stick and N-type cement base Seebeck effect stick, the end of every two adjacent cement base Seebeck effect stick
Portion a, metal film of corresponding flue lateral circuit plate surface, is realized and p-type cement base Seebeck effect stick and N-type cement base
The electric connection of Seebeck effect stick；
The temperature electromotive force forward direction at all p-type cement base Seebeck effect stick both ends is concatenated, each N-type cement base Seebeck
Effect stick is reversely concatenated with each p-type cement base Seebeck effect stick, two after all cement base Seebeck effect stick concatenations
A total exit should be arranged in indoor circuit board, and accumulator module, sensor module, wireless transport module should all also be arranged
Lateral circuit plate indoors；
Take p-type cement base Seebeck effect stick and the quantity of N-type cement base Seebeck effect stick identical and spatially interleaved
Arrangement, and numbered, all odd-numbereds are p-type cement base Seebeck effect stick, and even-numbered is N-type cement base
Seebeck effect stick, the two quantity is equal, its indoor circuit board one end of p-type cement base Seebeck effect stick of the first number
The metal film of contact is a total exit, the p-type cement base Seebeck effect stick of the first number and flue lateral circuit plate one end
Metal diaphragm contacts, the metal film with second number N-type cement base Seebeck effect stick contact, i.e., first number p-type water
Mud base Seebeck effect stick and the N-type cement base Seebeck effect stick of the second number share a piece of gold on flue lateral circuit plate
Belong to film, realizes and be electrically connected；The metal film of N-type cement base Seebeck the effect stick other end and indoor circuit board of second number
Contact, the metal film are contacted with the p-type cement base Seebeck effect stick that third is numbered, i.e., the N-type cement base of the second number
Seebeck effect stick and the p-type cement base Seebeck effect stick of third number share piece of metal on lateral circuit plate indoors
Film is realized and is electrically connected；And so on, until the indoor circuit board of the N-type cement base Seebeck effect stick contact of maximum number
On metal film be another total exit.
