Household Appliances Intelligent Control and Energy Management System Design

Household appliances control

At present, the control methods of household appliances mainly include manual control, mechanical timing control, remote control and microcomputer control.

Manual control

Manual control is the control method used by most of the previous household appliances. After the household appliance is plugged in, the household appliance can be operated normally by pressing the power switch by hand, such as an electric kettle, an electric hot pot, and a hair dryer.

2. Mechanical timing control

The mechanical timing control is to install a mechanical timer in the household appliance. After the household appliance is plugged in, the timer is rotated by hand to set the working time of the electrical appliance. After the electrical appliance exceeds the working time, the appliance is turned off or enters a thermal state, such as electricity. Rice cookers, fans, etc.

3. Remote control

Remote control is the use of infrared remote control to control the work of household appliances, such as air conditioners, televisions, video players and digital TV set-top boxes.

4. Microcomputer control

Microcomputer control is also called automatic control. It is the control method used for home appliances produced in the near future. It uses the internal single-chip microcomputer of the household appliances to design various working procedures in advance. After the household appliances are plugged in, they are pressed down.

Intelligent Control Design for Household Appliances

The intelligent control design of household appliances is based on the control of the host computer to unify the control of indoor various home appliances without changing the control method of the existing home appliances.

The intelligent control system for household appliances is mainly composed of two parts: hardware and software. The software is partially integrated inside the control host and is generally completed by the manufacturer. The hardware part mainly includes a control host, a smart socket, and an infrared transponder.

There are currently three kinds of smart sockets, one is a one-way control smart socket based on radio frequency wireless control, that is, the power socket can only receive the control information of the control host; the other is a bi-directional control smart socket based on ZigBee wireless networking, ie power The outlet can not only receive the control information of the control host, but also can return the switch status and operating parameters of the home appliance to the control host, and control the host to receive the return information before analyzing and processing. If the power outlet can transmit the value of the power supply voltage to the control host at any time, the control host can automatically shut off the power supply when the power supply voltage is unstable, and send a warning message to the user. The third type is a Wi-Fi wireless smart outlet, which is different from it. See the introduction above.

The function of the infrared transponder has been introduced before. It is an indispensable device in the intelligent control system for household appliances. It can replace a variety of infrared remote controllers with a smart phone or a tablet computer. For example, the user used to watch TV programs. Using TV remote controllers, digital TV set-top box remote controllers, and sometimes DVD remote controllers, the use of home appliance intelligent control systems eliminates the hassle of learning to use many remote controllers and makes it easy to control various appliances in the home.

The intelligent control system for household appliances can not only facilitate the remote control of various indoor electrical appliances, but also realize the remote control of household appliances. That is, the mobile phone or tablet computer can be used at any time and any place to control the on-site air conditioner, washing machine, television, micro cooker, induction cooker, etc. via the Internet and mobile phone wireless network. If you are on the way home, you can use your mobile phone to turn on your home's air conditioners or electric water heaters, so that when you enter the door, you have a comfortable living environment.

The intelligent control system for home appliances also has features such as one-button multi-machine control or combination with lighting as scene control, and can also cooperate with the control host to realize remote scene control of household appliances.

The intelligent control design of household appliances should be based on the distribution of indoor household appliances, and smart power outlets and common power outlets should be designed and installed. Household appliances controlled by infrared transponders, such as air conditioners and televisions, can be installed with ordinary power outlets, but they must be controlled first. The host learns the infrared remote control of the air conditioner and TV set to the infrared transponder.
