House renting network system provided with power amplifying circuit

Abstract

The invention discloses a network system for house rental with a power amplifying circuit, which is characterized in that it includes a central controller, a camera, a server, an intelligent lock, and a displacement sensor. There are multiple displacement sensors, and each house Displacement sensors are installed on the home, and the information detected by the displacement sensors is transmitted to the central controller. The camera is set at the door, and the image information collected by the camera is transmitted to the central controller. The central controller controls the smart lock according to the command from the server. The furniture is embedded with a radio frequency chip, and a card reader is installed at the door. The information detected by the displacement sensor is transmitted to the central controller after being sequentially passed through the sampling circuit, the filter circuit and the power amplifier circuit; the power amplifier circuit : Including operational amplifier U1 and operational amplifier U2, resistor R1 is connected in series with the non-inverting input terminal of operational amplifier U1. Realize the advantages of reducing rent costs.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a network system for house rental with a power amplifying 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 a network system for house rental with a power amplifier circuit to achieve 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 network system for house rental with a power ampl...
