Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example

[0017] Please see Figure 1-2 This utility model provides a technical solution: a wireless smart socket control system for home use, including a smart controller and a wireless communication module. The smart controller includes an MSP430F149 microcontroller, a power conversion circuit, a clock circuit, a relay module, an AC voltage / power detection circuit, and an audible and visual alarm circuit. It is mainly responsible for data processing, system power supply, timing, and workload control. The wireless communication module includes a WIFI communication module and a SIM900A module. This part is used for transmitting and receiving signals and is the bridge between the user and the smart controller. It plays a leading role in the USB interface.

[0018] It also includes a 5V / 2A USB interface, which can expand the system or charge mobile phones or tablets. The power conversion circuit and AC voltage / power detection circuit are both connected to the MSP430F149 microcontroller. The output of the MSP430F149 microcontroller is electrically connected to the LCD12864, and the input of the MSP430F149 microcontroller is electrically connected to the GSM module. The input of the GSM module is connected to the SMS control. The MSP430F149 microcontroller is electrically connected to the audible and visual alarm circuit.

[0019] The input end of the WIFI communication module is connected to a mobile APP;

[0020] The output terminal of the relay module is electrically connected to a socket.

[0021] Working Principle: The smart socket can operate in normal mode or timer mode, which can be switched via a mobile app. After the system is powered on, the power is converted to DC 5V or 3.3V through a power conversion circuit to supply power to devices such as the MSP430 microcontroller, Wi-Fi signal, and relays. Then, through an AC voltage (current) transformer, the system uses the instantaneous voltage (current) collected for pre-checking the normal voltage / current range before entering the system. If the system detects that the voltage (current) value is outside the set range, the relay immediately cuts off the power and issues an audible and visual alarm. During operation, the mobile app communicates with the microcontroller via the Wi-Fi module and controls the relay's on / off state. When the power load is running, if the voltage (current) rises above a preset threshold, the relay cuts off the power and sends an audible and visual alarm, providing protection for household appliances and the smart socket.

[0022] When the relay is de-energized, the user can set the system time via a mobile app. When the time expires, the relay is energized and loads the main circuit. While the relay is active, the de-energizing time can be set. Throughout the process, it continuously monitors the system's power and voltage (current) values ​​to check if they exceed set thresholds. All voltage (current), power, and time information can be displayed on the LCD12864 screen.

[0023] A stable power supply is essential for safe and proper operation. The system chip offers both 5V and 3.3V power supplies. To improve the safety of terminal devices and reduce system design costs, we designed a power conversion process, see [link to relevant documentation]. Figure 2The system is connected to 220V AC, which is then stepped down to 12V AC via a transformer. An AC-DC converter then converts the 12V AC to 12V DC. The system chips require 5V DC and 3.3V DC. Therefore, two voltage reduction steps are necessary: ​​first, converting 12V DC to 5V DC, and then converting 5V DC to 3.3V DC. The 12V DC powers the GSM module, the 5V DC powers the display screen, audible and visual alarms, and relays, and the 3.3V DC powers the WiFi module.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
