As shown in FIG. 1 , the present invention provides a home control system and method based on a smart speaker. This embodiment mainly provides a home control system and method for regulating and controlling light strip switches. Compared with the prior art, all the The light strip is designed to work independently, and a single voice control is used to control the work of multiple light strips, instead of controlling all the light strips at one time, thus saving power and protecting energy.

Among them, the home appliance classification module divides the home appliances into a light strip partition module 1 and an independent control electric appliance module. The independent control electric appliance module includes a TV, an air conditioner, a refrigerator, and a curtain.

The principle of using smart speakers for smart home control is: classify household appliances, and set up an independent microcontroller processor in each household appliance; The speaker converts the voice commands into control commands for controlling various household appliances; after the microcontroller receives the control commands, it controls the household appliances to perform corresponding operations.

The light strip partition module 1 is used to divide the light strip into a plurality of independently controlled panels according to the home area.

The micro-control unit 2 is connected with each light strip partition module 1, and is used for controlling the power-on and power off and working mode of each light strip partition module 1.

The light strips in the light strip partition module 1 include ambient lights suitable for different occasions and lights with different brightness levels. The micro-control unit 2 defines the usage scenarios of the ambient lights as various life scenarios. Select the working mode of the lighting according to the program set by the time point.

The smart speaker 3 is connected with the micro-control unit 2 through Bluetooth or wireless network communication, and is used for sending control commands of voice conversion to the micro-control unit.

The positioning identification unit 4 is installed on each of the light strip partition modules 1, and is used to determine the relative distance between each of the light strip partition modules 1 and the smart speaker 3, and to identify each of the light strip partitions User action within module 1.

Specifically, the positioning identification unit 4 includes a positioning chip 401 and an infrared sensor 402, and the smart speaker 3 determines the relative position between the light strip partition module 1 and the smart speaker 3 by identifying the positioning chip 401 , the smart speaker 3 monitors the user action of each of the light strip partition modules 1 through the infrared sensor 402 to automatically control the power-off operation of each of the light strip partition modules 1 .

The voice recognition unit 5, installed in the smart speaker 3, includes a sound wave recognition component 501 and a sounding position recognition component 502, the sound wave recognition component 501 is used to identify the user identity of the control command, and the sounding position recognition component 502 502 is used to determine the relative position between the control instruction and the smart speaker 3 .

A plurality of light strip partition modules 1 adjacent to the current moving position are turned on at the same time to work.

As the innovation point of this embodiment, the existing patents, such as the invention patent with application number 201911071743.7, mainly use the combination of infrared sensors and light intensity sensors to realize the regulation of home light strips, so the user's body must move to the corresponding Only after the light strip area is located, the light strip in the light strip area can be turned on. Obviously, the user experience is poor, and the user is easy to fall in the dark space.

In order to solve the above problems, this embodiment uses a remote control method to determine the regulation of a certain light strip, to determine the movement path of the user from the current position to the target light strip area and the corresponding light strip, and in the process of the user's movement, The light strips included in the moving path are turned on in turn, so that before the user enters the dark space, the light strip can be automatically turned on and adjusted, thus avoiding the existing home control system "people are advanced, lights are advanced". The drawbacks of "behind the light".

At the same time, the way of controlling the automatic turn-off of the light strip in this embodiment is controlled by the combination of the infrared sensor and the light intensity sensor. Therefore, when a light strip area is still not used by a user after a period of time, the light strip will automatically turn off the lights. In order to solve this problem, the light strips of this embodiment are turned on in sequence, avoiding the problem of turning on all the light strips on the moving path at one time and automatically turning off the lights, thereby further improving the use experience.

It is further explained that the moving path planning unit 7 plans the moving path of the user according to the position of the user who issued the voice command and the position of the lighting area to be turned on, and the specific implementation steps are:

The smart speaker 3 determines the current position of the user according to the infrared sensor 402 of each of the light strip partition modules 1, and sequentially controls the light strip partition modules 1 on the moving path to turn on lights.

Wherein, the switch control time period of the infrared sensor 402 of each of the light strip partition modules 1 when no human body is detected is 10-20 minutes.

Therefore, this embodiment avoids voice control of all light strips being powered on or powered off at the same time. All light strips are designed to work independently, and a single voice control is used to control the work of multiple light strips, which saves power and reduces energy waste. It is also in line with the user's living habits and will not bring trouble to the user.

The smart speaker converts the voice commands and sends them to the microprocessor. The light intensity sensor on the light strip module simultaneously controls the power-on operation of the household light strip module.
