Intelligent system with amplifying circuit for house leasing

Abstract

The invention discloses an intelligent system with an amplifying circuit for house leasing. The intelligent system is characterized by comprising a central controller, a camera, a server, an intelligent lock and displacement sensors, wherein the displacement sensors are multiple, each piece of furniture in a house is provided with one displacement sensor, information detected by the displacement sensors is transmitted to the central controller, the camera is arranged at the door, image information acquired by the camera is transmitted to the central controller, the central controller controls the locking and unlocking of the intelligent lock according to commands from the server, the information detected by the displacement sensors is transmitted to the central controller through a sampling circuit, a filtering circuit and the amplifying circuit in sequence, the amplifying circuit comprises an operational amplifier U1 and an operational amplifier U2, and a resistor R1 is connected with a non-inverting input end of the operational amplifier U1 in series. The intelligent system with the amplifying circuit for house leasing achieves the advantage of reducing house rent expense.

Description

technical field [0001] The invention relates to the field of information processing, in particular to an intelligent system for house rental with an amplifier circuit. Background technique [0002] At present, with the development of the country's economy, the mobility of the population is also increasing, and the demand for renting houses is also increasing. However, when renting houses, most of them are rented through physical leasing companies. Although the use of leasing companies is convenient for the landlord, but The labor cost of the intermediary is passed on to the tenants, which pushes up the rent price. Contents of the invention [0003] The object of the present invention is to propose an intelligent system for renting a house with an amplifying circuit in view of the above-mentioned problems, so as to realize the advantage of reducing the rent. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A...
