Network system provided with sampling circuit and used for house leasing

Abstract

The present invention discloses a network system provided with a sampling circuit and used for house leasing. The network system is characterized in that the network system comprises a central controller, a camera, a server, a smart lock and displacement sensors; a plurality of displacement sensors are adopted; each hone appliance of 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 doorway of the house; image information collected by the camera is transmitted to the central controller; the central controller controls the opening and closing of the smart lock according to commands from the server; radio frequency chips are embedded in furniture; a card reader is installed at the doorway of the house; the information detected by the displacement sensors pass through the sampling circuit, a filtering circuit and an amplifying circuit sequentially, and then is transmitted to the central controller; the sampling circuit comprises an operational amplifier U1, an operational amplifier U2 and an operational amplifier U3; and a resistor R1 is connected with the in-phase input end of the operational amplifier U1. With the network system adopted, renting costs can be decreased.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a network system for house rental with a sampling 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 sampling 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 sampling circuit, includi...
