Design of household intelligent security system based on single chip microcomputer

Abstract

A temperature sensor, a smoke broadcaster, a carbon monoxide sensor and an infrared sensor are controlled by a single chip microcomputer, and the temperature value, the smoke concentration value, the gas concentration value, and whether there is someone breaking in are displayed on a liquid crystal display in real time. If a host is at home (set by a button), the voice broadcasts 'The current indoor temperature is too high, please be careful of fire!' when the temperature is too high, the voice broadcasts 'There is smoke inside now, please check whether there is fire!' when the concentration of smoke is too high, the voice broadcasts 'The concentration of gas is too high inside, please check whether there is gas leakage and ventilate the room and close the valve in time!' when the concentration of leakage gas is too high, and the voice broadcasts 'Someone breaks in!' when someone breaks in. If the host is not at home (set by the button), when these happen, texts in the voice information can be sent to the host through a GSM module.

Description

technical field [0001] The invention relates to the field of home security systems, in particular to the design of an intelligent home security system. Background technique [0002] With the rapid development of society and the improvement of living standards, liquefied petroleum gas, piped gas or natural gas have entered most urban households, and people's lives are inseparable from various home appliances. Many changes have been made in life, but also increased risk of fire and gas poisoning. At the same time, the rapid development of modern cities has added many new problems. Cases such as burglary and robbery often occur. More and more people urgently need a safe living space. Now the main protective measure is to protect the house through anti-theft windows or anti-theft nets. Although it has a certain anti-theft effect, it is very unsightly and brings more security risks, so the home smart security system came into being. Contents of the invention [0003] The main...
