In the above, the present application further provides a technical solution that the host module controls the load module of the slave module through the power signal bus.
Specifically, under special conditions, when the slave load module needs to be started, the master single-chip microcomputer outputs a pulse width modulation signal to the electric energy signal bus through the Q2, then the pulse width modulation signal is transmitted to the slave module, then the signal is transmitted to the interrupt input pin of the slave single-chip microcomputer through the D2, the slave single-chip microcomputer is immediately awakened after receiving an external interrupt signal, the slave single-chip microcomputer exits from a low power consumption mode, then the master single-chip microcomputer sends a load control pulse width modulation signal to the slave single-chip microcomputer, the slave replies a control response pulse width modulation signal through the Q3, and the master single-chip microcomputer receives a signal returned by the slave through the D1. Then the slave single chip microcomputer turns on a slave load module control switch Q4, the master single chip microcomputer turns on Q1, and at the moment, Q2 and Q3 are both in a closed state, so that the load module is turned on. When the slave load module needs to be shut down, the master single-chip microcomputer first shuts down the Q1, the slave single-chip microcomputer detects a low level signal through the D2, and the slave single-chip microcomputer shuts down the Q4, so that the load module is shut down. The role of R1 is to limit current, in the case of opening a relatively large load.
As shown in fig. 4, fig. 4 is a flowchart illustrating a master module controlling a slave load module to be turned on according to the present disclosure.
