Safe and energy-saving monitoring terminal for household power and gas consumption

Abstract

The invention provides a safe and energy-saving monitoring terminal for household power and gas consumption. A liquefied gas sensor and a carbon monoxide sensor of the safe and energy-saving monitoring terminal are used for detecting harmful gases in a room and automatically controlling an exhaust fan to work, so as to exhaust the harmful gases; when the harmful gases can be still detected after the exhaust is continued for a period of time, the alarm is realized in sound, light and mobile phone short message ways; the work of a relay connected to an air conditioner and a socket and a power supply of the relay can be controlled in a keyboard-input, infrared remote control or mobile phone short message way; when doors and windows are opened, a power supply of the air conditioner is automatically closed by detecting a door / window magnetic control switch, so that the effect of saving energy is achieved; an LCD (Liquid Crystal Display) is used for displaying the states of each switch, each relay and each sensor in a liquid crystal way so as to bring convenience for observation and operation; and the states of each sensor, each switch and each relay can be remotely queried to learn the conditions in the house and the work of the relay can be remotely controlled in the mobile phone short message way.

Description

technical field [0001] The invention relates to the technical field of automatic control and remote monitoring, in particular to a control technology for monitoring indoor liquefied gas, harmful gas concentration of carbon monoxide, opening and closing of doors and windows, automatic and remote control of exhaust fans, air conditioners and sockets. Background technique [0002] The application of MQ series sensors in harmful gas monitoring has matured, and there are already sensor networks or wireless sensor networks combined with RS-485 bus; the technology of remote control through mobile phone calls or sending text messages is also developing rapidly, and this technology has matured. There are already technologies for remote control through mobile phones, such as mobile phone remote control detonators, etc.; most of the existing residential area monitoring systems use RS-485 bus networking to realize access control systems and video monitoring, etc., due to the presence of ...

AI Technical Summary

Problems solved by technology

[0003] The safe use of electricity and gas has always been a major fire protection problem for families, especially when only the elderly and children are at home. Due to their lack of safety awareness, it may cause liquefied gas leakage, and burning charcoal and coal for heating in winter may produce carbon monoxide and other harmful substances. Gas, or use electric fire, turn on the air conditioner to heat, and turn on the air conditioner to cool in summer, etc., which will cause the electrical equipment to run for a long time, which can easily cause disastrous consequences. The automatic control and remote monitoring system designed for household electricity and gas consumption Has high practical value
