Smart home security and protection system

Abstract

The invention discloses a smart home security and protection system, and the system comprises a vibration sensor, a gate magnetic and window magnetic sensor, an infrared sensor, a smoke sensor, a temperature sensor, a smoke sensor, a flow sensor, a pressure sensor, a first signal processing circuit, a second signal processing circuit, a third signal processing circuit, a power carrier communication circuit, a microprocessor, a keyboard, a camera, a drive circuit, a relay, an electric bell, a display, a wireless communication module, a mobile terminal, a voice alarm circuit, and an Ethernet interface. The mobile terminal is provided with a smart home security and protection APP. The drive circuit comprises a triode, a rectification diode, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a first capacitor, a second capacitor, and a power supply. The system has many functions, can achieve the remote monitoring and querying of the home safety condition at any time and places, and improves the safety and reliability of the circuit.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a smart home security system. Background technique [0002] With the continuous improvement and improvement of modern home life, people's security needs for the home environment are no longer satisfied with simple anti-theft. In the case of meeting the anti-theft function, it is also necessary to prevent fire prevention and gas poisoning. The security systems that appear on the market now have relatively single functions, only have simple anti-theft functions, and cannot realize remote real-time monitoring and query of family security conditions. In addition, the drive circuit of the relay in the existing security system lacks a corresponding circuit protection function, resulting in poor circuit safety and operational reliability. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a smart home with various functions, which c...
