The indoor main control system The system communicates with the indoor parameter detection and equipment control unit through the wireless module. The user's mobile phone terminal mainly realizes that the user can control the indoor equipment by sending the mobile phone text message and receive and view the relevant alarm information through the mobile phone.

The beneficial effects of the utility model are as follows:

The monitoring of indoor environmental parameters (including temperature, humidity, luminosity, human body infrared signals, etc.) can be realized through various sensors. Users can set various environmental parameters and control the working status of related equipment through the main control system installed indoors. , so that the indoor environmental parameters are automatically maintained within the range set by the user. If any parameter exceeds the set range, an instruction will be sent automatically to control the corresponding equipment to change the indoor environmental parameters, such as turning on/off the humidifier, controlling the curtains The degree of light transmission, the closing/opening of windows, pyroelectric sensors and photoelectric sensors are installed in places that do not require long-term lighting such as kitchens and bathrooms, and the working status of lighting equipment is automatically controlled according to the current luminosity and whether there are personnel activities . The lighting in the living room automatically adjusts its brightness according to the ambient light. The system can also automatically control the status of drying racks, doors, windows, curtains, etc. according to weather conditions. Since each sensor and the lower computer, between the lower computer and the upper computer, between the equipment to be controlled and the lower computer, and between the lower computer and the user's mobile phone are all connected by wireless communication, so the trouble of wiring is avoided, and the system structure is very simple. , easy to install.
