Interrupt multiplexing system and method and electronic equipment

The invention discloses an interrupt multiplexing system and method and electronic equipment, and relates to the technical field of Internet of Things equipment. The system comprises a main control unit, and a low-power-consumption interruption port, an analog-to-digital converter and a general input/output interface unit which are connected with the main control unit, the system also comprises a plurality of interrupt sources connected with the low-power-consumption interrupt port, the plurality of interrupt sources multiplex one path of the low-power-consumption interrupt port, and the plurality of interrupt sources are connected with one path of a common interface of the analog-to-digital converter or an independent interface of the universal input/output interface unit. And the main control unit detects the level of the interface of the analog-to-digital converter or the state of the interface of the single general input/output interface unit based on the preset level to determine a target interrupt sourc
