Abstract

The invention discloses a power switching system, a control method and device thereof and a motor home air conditioner power supply system. The system comprises a plurality of power supply input endsand power supply output ends. The power switching device disconnects the first power supply input end and the first power supply output end if detecting that the second power supply input end is connected to the second power supply under the condition that the first power supply input end and the corresponding first power supply output end are connected to the first power supply, and the second power supply input end is connected with the corresponding second power supply output end, and the second power supply input end is any power supply input end different from the first power supply inputend. The technical problem that in the prior art, the switching mode of power supply switching of a motor home air conditioner power supply system is prone to causing multiple power supplies to supply power to an air conditioner at the same time is solved.

Description

technical field [0001] The present invention relates to the field of air conditioner control, in particular to a power switching system and its control method and device, and a power supply system for an air conditioner in a caravan. Background technique [0002] At present, RV air conditioners are not only powered by a single power source, but can use energy such as mains power, batteries, solar energy, and hydrogen energy for storage, and then convert it into AC power through an inverter to power compressors or fans. Faced with the diversification of power supply solutions, users need to frequently adjust the power input when switching power supplies. [0003] At present, the commonly used power switching schemes include manually setting the switch, chip-controlled relay disconnection, etc., which may cause switching abnormalities caused by hasty switching, and multiple relays controlled by the chip port are closed to cause simultaneous power supply; it is also easy for us...
