When the product leaves the factory, the default wire 10 is normally connected, and at this time, the product is in a power-off low-power consumption state. After the product is installed, when the machine needs to be started, the lead is cut off manually. When the product detects that the lead is disconnected, normal operation is started, so that the product is started. The beacon is always in a power-on running state after being powered on, and generally does not need to be powered off again.
And if the power-off is needed, connecting the disconnected wires.
Referring to fig. 5, the specific implementation process of booting is as follows: a certain pin P in the mcu (microcontroller unit) is connected to the positive power supply VCC through a resistor R. Meanwhile, pin P is directly connected to power ground GND, and the conductor 10 outside the product body connects pin P to power ground GND, so that pin P is actually at a low level in this default case.
When the pin P is disconnected from the power ground GND, i.e. the lead 10 outside the product body is cut off, as shown in fig. 4, or the conductive cloth/conductor is pulled out, the pin P is pulled to a high level by the power VCC through the resistor R.
When detecting that the pin P is at low level, the power supply automatically turns to a low-power-consumption shutdown state. When detecting that the pin P is at high level, the power supply automatically turns to normal power-on operation state.
