Then the slave singlechip turns on the slave load module control switch Q4, and the host singlechip turns on the Q1, so that both the Q2 and the Q3 are in a closed state, and the load module is turned on. When the slave computer load module needs to be closed, the host computer singlechip firstly closes Q1, the slave computer singlechip detects a low-level signal through D2, and the slave computer singlechip also closes Q4 at the moment, so that the load module is closed. The function of R1 is a current limiting function, in the case of a relatively large load being turned on.
Fig. 4 is a flowchart of a master module controlling a slave load module to be turned on according to the present application, as shown in fig. 4.
Through the interaction method in the low-power-consumption control system, the host module and the slave module realize the low-power-consumption circuit with the power supply and communication functions through double wires and the low-power-consumption processing method, and the technical scheme solves the technical blank of realizing the power supply and communication through double wires under the low-power-consumption system;
