Among them, in the voice recognition intelligent control system based on power carrier of the present invention, the host computer can work independently or communicate with each other.

For example: when the host is working independently, the host will not receive instructions through the power carrier module, but only collect voice instructions through the voice recognition module of the machine, and then control household appliances through the output execution module.

For example: the process of hosts communicating with each other is that when the voice recognition module of one of the hosts (assumed to be host A) collects voice commands, the voice commands are recognized and judged by the main controller CPU of host A and then converted into digital compression The signal is then sent to the power network through the power carrier module of host A, and then transmitted to another host (assumed to be host B) through the power network. The main controller CPU of host B receives the above-mentioned digital compressed signal through the power carrier module of this machine, Then the main controller CPU of host B decompresses and restores the instruction, and finally the main controller CPU of host B sends the instruction to the output execution module of the machine, and the output execution module controls the corresponding household electrical equipment according to the instruction.

Assume that host A is installed in room 1, and the slave output physical execution module A1 is installed on the light in room 1; suppose host B is installed in room 2, and the slave output physical execution module B1 is installed on the light in room 2 on; and so on;

1. In-room control: When it is necessary to turn on the light in room 1, the user in room 1 can say "turn on the light", and the voice recognition module of host A will collect the voice of "turn on the light" Instructions, and then control the lights in room 1 to turn on through the physical execution module A1 output from the slave; wherein, because the hosts in other rooms cannot collect voice commands or very weak voice commands, the lights in other rooms will not be turned on;

2. Control outside the room: When it is necessary to turn on the light in room 2, the user in room 1 can say "turn on the light in room 2", and the voice command of "turn on the light in room 2" is sent by the host A's The main controller CPU recognizes and judges and converts it into a digital compressed signal, and then sends it to the household power network through the power carrier module of host A, and then transmits it to host B through the household power network. The main controller CPU of host B passes the power carrier module of the machine After receiving the above-mentioned digital compression signal, the main controller CPU of host B decompresses and restores the command, and then controls the lighting in room 2 to turn on through the output physical execution module B1 of the slave. In the same way, the control between other rooms is the same. Of course, this kind of mutual control can be combined arbitrarily, and there is no distinction between master and slave, but there is priority identification.

To sum up, the voice recognition intelligent control system based on the power carrier of the present invention can realize the daily control of household appliances through voice commands, such as: switching lights, adjusting the brightness of lights, switching electric water heaters, electric curtains, fans, TVs, etc. , time reporting, temperature and humidity registration and so on.
