Abstract

The present invention discloses a multi-control adapter used for fresh air, and relates to the adapter technology field. The multi-control adapter comprises an input signal processing circuit, a processor, a relay output circuit and a power supply circuit, the input signal processing circuit is connected with the input end of the processor, the output end of the processor is connected with the relay output circuit, and the power supply end is connected with the power supply circuit. The voltage input end of the power supply circuit is 12v-24v voltage input and becomes the 5v voltage output after the voltage stabilization processing of a voltage stabilizing circuit in the power supply circuit, the input signal processing circuit inputs a voltage signal to an optocoupler of the input signalprocessing circuit via the AC voltage input and after the rectification of a rectifier bridge of the input signal processing circuit, a 5v-0v square wave signal having the same frequency with a 220v AC voltage is generated at the output side of the optocoupler and is inputted to the processor, and the processor determines whether a line has an input voltage according to the square wave signal. Themulti-control adapter of the present invention avoids the situation that the output conflicts damage the equipment, guarantees the normal work of a system, at the same time, realizes the simultaneoususage of multiple equipment.

Description

technical field [0001] The invention relates to a multi-control adapter for fresh air, belonging to the technical field of adapters. Background technique [0002] When the existing fresh air fan needs to be controlled, it needs to be realized by the controller, but the existing controller is prone to conflicts during use, causing the fresh air fan to not work normally or burn out. Contents of the invention [0003] In view of the above problems, the technical problem to be solved by the present invention is to provide a multi-control adapter for fresh air. [0004] A multi-control adapter for fresh air of the present invention comprises an input signal processing circuit, a processor, a relay control circuit, and a power supply circuit; the input signal processing circuit is connected to the input end of the processor, and the output end of the processor is connected to the relay control circuit , the power supply terminal of the processor is connected to the power supply...
