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, ...

Embodiment Construction

[0008] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0009] figure 1 Among them, 1 is the interface circuit of MBUS equipment, which can be composed of TSS721A integrated circuit as the core, and the TSS721A integrated circuit is connected to the first asynchronous serial communication port of the microcontroller MCU. Let the TSS721A integrated circuit work in the external power supply mode, the working current is set to 12mA, and the parameters of each component can be used in its data sheet. The MBUS device interface circuit is connected to the RS-232 / MBUS bus transponder with the application number of 201210257258.0 through a pair of twisted pairs, and the RS-232 / MBUS bus transponder is then connected to the host computer through the RS-232 bus. The host computer can be a GSM module or PC with RS-232 interface. The host computer can inquire about the switching status of the relay group, the opening status o...

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 ...
