Wireless sensing system with backup power
A wireless sensing system includes a power supply unit, a control unit, a backup power unit, and a wake-up unit. The control unit includes a microprocessor. The microprocessor acts according to a forced shutdown instruction and transmits the forced shutdown instruction to the wake-up unit through an internal control pin in order for the wake-up unit to generate a forced shutdown clock matching the forced shutdown instruction, transmit the forced shutdown clock to the power supply unit, and thereby stop the power supply unit from generating electricity, and for the backup power unit to transmit the electricity stored therein to the wake-up unit and thereby enable the wake-up unit to maintain its basic electrically driven functions. The backup power unit can supply a small amount of electricity to sustain the basic electrically driven functions of the system.
