Specific working process:

Fig. 1 is a schematic diagram of the structure principle of the utility model, and the smart socket is composed of an STM single-chip microcomputer, a power supply module, a 433M wireless module, a relay and a button. The power supply module is 220V AC input, after the power supply module outputs 15V DC, the 15V DC outputs 3.3V DC through the 3.3V regulator chip to supply power to the STM microcontroller and 433M wireless module, the 433M wireless module has an antenna for receiving and transmitting wireless signals, STM The microcontroller is used to control the opening and closing of the relay. STM microcontroller and 433M wireless module adopt SPI communication protocol, the button can give STM microcontroller control signal, smart socket and smart host use 433M wireless communication method for two-way communication, smart host and mobile phone communicate through the network.

The STM microcontroller uses STMS103F3P6, the 3.3V regulator chip uses the 7533 voltage regulator chip, the 433M wireless module uses the SI 4463 wireless communication module, and the relay uses a 5V/16A relay. The 433M wireless module is used to realize the wireless communication of the socket.

Each independent intelligent socket of the utility model has a unique ID number, and the communication commands between the socket and the intelligent host include a host operation command, a host query socket state command, a manual operation command, and a learning command. After pressing the button on the socket for 5 seconds, the indicator light will flash once, indicating that the socket is in the learning state. At this time, the host sends a learning command to obtain the unique ID number of the smart socket. The smart host sends commands to the socket according to the ID number. After the socket with the ID number receives the command, the STM microcontroller executes the corresponding operation according to the corresponding command. After receiving the host’s open operation command, the relay closes and the LED lights up and replies the information that the socket has been opened to the host, and saves the open state to the EEPROM. , after receiving the host switch operation command, the relay is disconnected, the LED light goes out, and the information that the socket is closed is returned to the host, and the off state is saved to the EEPROM. When receiving the host query socket status command, the STM microcontroller reads the status of the socket from the EEPROM and replies the status of the socket at this time to the host. When manually operating the button to control the socket, the timer scanning method is used to detect the button is pressed, and wait to let go after detecting that the button is pressed. After the button is released, the socket state is reversed and the socket state is sent to the host, and the socket state is saved in EEPROM. The host will reply to the socket after receiving the manual operation command. If the socket does not receive the reply from the host, it will send the status of the socket to the host again every 1s. It can send up to three times, and it will stop sending until it receives the reply from the host.

The state of the EEPROM storage socket adopts the following scheme: the STM microcontroller has its own EEPROM inside, and the EEPROM starts to store data 50 times from the first storage unit, and then transfers to the next unit to store data 50 times, and so on, when the last unit is stored 50 times , and go to the first cell to start storing again. This is beneficial to improve the storage life of the EEPROM and prolong the service life of the socket. After the socket is powered off, the socket will read the state before the state in the EEPROM is restored when the socket is powered on again.

The smart socket provided by the utility model can respond to the commands sent by the smart host in time to perform corresponding actions and automatically reply the response signal while saving the socket state, and can manually control the power on and off of the socket through the buttons on the socket and actively send the socket state to the smart socket. The host also saves the status of the socket, and there is an indicator light on the socket to indicate the status of the socket in real time. By using the smart socket in a smart home system, stable two-way communication, real-time acquisition of the socket state, and real-time storage of the socket state can be well realized. Specifically, it can be applied in homes, communities, corporate office environments, hotels and other places to provide users with efficient and convenient work and lifestyle.

The above is only the preferred embodiment of the utility model, and it should be pointed out that, for those of ordinary skill in the art, some modifications can also be made without departing from the principle of the utility model, and these improvements should also be considered Within the protection scope of the present utility model.
