In order to enable the charging box to be in a sleep state when the charging box is not used, and to enable the charging box to exit from the sleep state and enter into an operating state when the charging box is operated, referring to fig. 1, in the present embodiment, the MCU 1 may output an interrupt signal 1, an interrupt signal 2, and an interrupt signal n for performing different operations on the charging box, and output the signals to the electronic circuit 1 and the electronic circuit 2, which perform the respective operations correspondingly, and the electronic circuit n is configured not to perform the operation on the charging box when the interrupt signal is valid (for example, the interrupt signal is at a high level), and to perform the operation on the charging box when the interrupt signal is invalid (for example, the interrupt signal is at a low level).
The comparison and judgment module 2 receives the interrupt signals 1, 2 and n, and outputs a judgment signal to the MCU 1 after comparison and processing, and the MCU 1 controls the charging box to be in a working state or a sleep state according to the judgment signal.
For example, when the interrupt signal n is valid, the charging box is not operated, that is, the charging box may not be used, and the comparison and determination module 2 may output a determination signal according to each interrupt signal, so that the MCU 1 controls the charging box to enter the sleep state, thereby reducing the power consumption of the charging box.
When at least one interrupt signal 1 and one interrupt signal 2 are valid, that is, when one or more operations are performed on the charging box, that is, the charging box should be used, the comparison and judgment module 2 may output another judgment signal according to each interrupt signal, so that the MCU 1 controls the charging box to exit from the sleep state and enter the working state.
In this embodiment, the comparing and determining module 2 may be a nand gate circuit.
The electronic circuit 1 and the electronic circuit 2 are used for outputting a first judgment signal of a low level to the MCU 1, and the charging box enters a sleep state.
If at least one interrupt signal is low level, it indicates that at least one operation does not enter into the interrupt, i.e. the electronic circuit 1 and the electronic circuit 2, at least one of the electronic circuits n executes at least one operation on the charging box, at this time, the nand gate circuit outputs a second determination signal of high level to the MCU 1, and the charging box exits from the sleep state and enters into the working state.
