When working, the system is powered on, and the microcontroller module is initialized. After initialization, the microcontroller module is in a cyclic waiting state, the status display module displays the current system status, and the real-time clock module displays the current time; the microcontroller module detects the Bluetooth communication module in real time. Whether there is a control command, if there is no control command, the microcontroller module continues to be in a circular waiting state; the wireless signal transmitting module sends out a control command, and when the Bluetooth communication module receives the control command, the microcontroller detects the control command and judges the control command Whether the command is a valid command, and return the command information to the wireless signal transmitting module for the user to check. If the command is invalid, the alarm module will send out an alarm sound, and the display module will display ERROR. If the command is valid, the corresponding command will be executed and realized through the controlled electrical interface module The power supply is controlled, and the status display module displays the current system status at the same time; after executing a task, the microcontroller module returns to the original cycle waiting state.
