All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a functional block diagram of a low power switch control circuit according to an embodiment of the present invention. As shown in fig. 1, the low power consumption switch control circuit 100 includes: the electronic switch module 20, the main control module 30, the man-machine interaction module 40, the photoelectric coupling module 50 and the locking module 60. Wherein,
the electronic switch module 20 is configured to determine that the main control module 30 can receive the power of the power supply 200 when turned on, and determine that the main control module 30 cannot receive the power of the power supply 200 when turned off. The power supply 200 may be a storage battery or a commercial ac power.
The man-machine interaction module 40 is configured to receive power of the power supply 200 and to accept a trigger operation to generate a trigger signal. The man-machine interaction module 40 can be any one of a key switch, a touch switch, a photoelectric sensing switch, a touch screen and a wireless control receiving circuit, and the wireless control receiving circuit can be a Bluetooth control receiving circuit, an infrared control receiving circuit and the like. In practical applications, the man-machine interaction module 40 may receive a triggering operation such as manual manipulation, touch, approach, wireless remote control, etc. to generate a triggering signal.
The optocoupler module 50 is configured to turn on the electronic switch module 20 and generate a characterization start signal in response to the trigger signal. The photoelectric coupling module 50 is affected by the trigger signal, so that the electronic switch module 20 is turned on, so that the main control module 30 can receive the electric energy of the power supply 200; in addition, the optocoupler module 50 also generates a characterization activation signal in response to the trigger signal.
The main control module 30 is configured to generate an on-state lock signal in response to the characterization start signal upon receipt of power from the power supply 200. The main control module 30 can be a microcontroller such as a singlechip, FPGA, ASIC, DSP and the like. After the electronic switch module 20 is turned on, the main control module 30 can receive the electric energy of the power supply 200, so that the main control module 30 is powered on and started, and the main control module 30 receives and responds to the characterization start signal to generate an on state locking signal.
The lockout module 60 is configured to lockout the electronic switch module 20 to the on state in response to the on state lockout signal. The locking module 60 receives and responds to the on-state locking signal to lock the electronic switch module 20 in the on-state, so that the electronic switch module 20 is continuously in the on-state all the time, and the main control module 30 can continuously receive the electric energy of the power supply 200 to control some types of load operation all the time.
The starting process comprises the following steps:
in the standby or off state, the electronic switch module 20 is in an off state, such that the main control module 30 cannot receive the power of the power supply 200, and some types of loads are not operated. When the man-machine interaction module 40 is triggered, a trigger signal is generated, the photoelectric coupling module 50 responds to the trigger signal to enable the electronic switch module 20 to be turned on, so that the main control module 30 can receive the electric energy of the power supply 200, in addition, the photoelectric coupling module 50 responds to the trigger signal to generate a characteristic starting signal, the main control module 30 responds to the characteristic starting signal to generate a conducting state locking signal when receiving the electric energy of the power supply 200, and the locking module 60 responds to the conducting state locking signal to lock the electronic switch module 20 into a conducting state, so that the main control module 30 can continuously receive the electric energy of the power supply 200 to control some types of load work, and the starting process is completed.
Static standby or shutdown process:
in the start-up state, the main control module 30 may be configured to generate the off-state locking signal under the condition that the preset condition is satisfied, and the locking module 60 is configured to lock the electronic switch module 20 into the off-state in response to the off-state locking signal, and since the electronic switch module 20 determines that the main control module 30 cannot receive the power of the power supply 200 when being turned off, the main control module 30 cannot control some types of load operations, thereby completing the static standby or shutdown process. The preset condition may be that the man-machine interaction module 40 is not triggered within a preset time period, or that a preset time point is reached, etc.
Dynamic standby or shutdown process:
in the start-up state, when the man-machine interaction module 40 is triggered, a trigger instruction is generated, the photoelectric coupling module 50 generates a characteristic stop signal in response to the trigger instruction, the main control module 30 generates an off-state locking signal in response to the characteristic stop signal, the locking module 60 is configured to lock the electronic switch module 20 in the off-state in response to the off-state locking signal, and since the electronic switch module 20 determines that the main control module 30 cannot receive the power of the power supply 200 when being turned off, the main control module 30 cannot control some types of load work, thereby completing the dynamic standby or shutdown process. It should be noted that the trigger instruction may be the same as the trigger signal, and the characteristic stop signal is the same as the characteristic start signal, for example, the trigger instruction and the trigger signal are both high-level signals, and the characteristic stop signal and the characteristic start signal are both low-level signals. The master control module 30 may be configured to determine a low level signal generated by the optocoupler module 50 in the on state as indicative of the stop signal, thereby generating an off state lock signal in response to the indicative of the stop signal; the master control module 30 may also be configured to determine the low level signal regenerated by the photocoupling module 50 as indicative of a stop signal, thereby generating an off-state lock signal in response to the indicative of the stop signal.

Some types of human-machine interaction modules 40 require only a few microamps of current to meet the operating requirements.

in the starting state, when the man-machine interaction module 40 is triggered, a high-level signal is generated to enable the NPN triode 52 to be turned on, the power supply 200, the PNP triode 22, the first resistor 23, the light emitting tube of the photocoupler 51, the NPN triode 52 and a current path are formed, the photoelectric receiving tube of the photocoupler 51 is turned on to enable the first output end of the photocoupler 51 to become low level, the main control module 30 responds to the low-level signal to generate an off-state locking signal, the off-state locking signal is a low-level signal enabling the NPN triode 61 to be turned off, the power supply 200, the PNP triode 22, the first resistor 23, the second resistor 62 and the NPN triode 61 cannot form a current path, and the NPN triode 21 is locked to be turned off, so that the main control module 30 cannot receive the electric energy of the power supply 200 and cannot control some types of load work, and thus the dynamic standby or shutdown process is completed.
