Problems solved by technology

At present, most of these measurement and control system subsystem modules are powered by a unified power supply, but sometimes, it is inconvenient to provide a unified power supply for these modules, and they need to be powered independently. If they are powered independently, they cannot control the standby and work of their respective modules through bus communication

Abstract

The invention discloses a zero-power-consumption standby and signal awakening device. The device comprises an MCU (microcontroller unit), a photoelectric coupler A and a photoelectric coupler B, wherein each photoelectric coupler comprises a primary side and a secondary side, the primary side comprises a light-emitting diode, the secondary side comprises a secondary side triode, an emitter of the secondary side triode of the photoelectric coupler A and an emitter of the secondary side triode of the photoelectric coupler B are connected with a complete machine power supply, a collector of the secondary side triode of the photoelectric coupler A and an anode of the primary side light-emitting diode of the photoelectric coupler B are connected through a lead, and a power taking point C is arranged on the lead; a collector of the secondary side triode of the photoelectric coupler B and a VCC on the MCU are both connected with the power taking point C, a GPIO end of the MCU is connected between the photoelectric coupler B and a resistor, and the other end of the resistor is grounded.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a zero-power consumption standby and signal wake-up device. Background technique [0002] More and more household appliances and electronic products have a standby function. The standby function reduces the number of times of manual power-off and startup, which is convenient for users. However, there is still a certain amount of standby power consumption in standby, and a long-term standby state will cause a large waste of electric energy. Now in electronic products, especially in the field of measurement and control, there are more and more distributed measurement and control systems. Usually, a distributed measurement and control system is divided into a main control module and several sub-modules. Each module is connected and coordinated by a bus. get the job done. At present, most of these measurement and control system subsystem modules are powered by a unified power s...
