Document Type and Number:
WIPO Patent Application WO/2022/068278
Kind Code:
A1
Abstract:
The present invention relates to the technical field of air conditioners, in particular provides an outdoor unit communication method of a several-driven-several multi-split air conditioner and the several-driven-several multi-split air conditioner, and aims at solving the problems of low communication speed and poor communication quality between the existing indoor units and outdoor units. The method comprises: determining an average communication bit error rate and a maximum communication bit error rate of indoor units; comparing the average communication bit error rate and an average communication bit error rate threshold, and comparing the maximum communication bit error rate and a maximum communication bit error rate threshold; determining levels of internal tasks according to comparison results; and selectively executing a first communication strategy according to the levels, or hierarchically disassembling a zero-level task into a plurality of sub-tasks to form new internal tasks, and then executing a second communication strategy, or executing a third communication strategy. According to the method, high-level internal tasks are hierarchically disassembled, the operation frequency of external communication tasks in one communication period is increased, communication speed of an outdoor unit is increased, communication speed between the indoor unit and the outdoor unit can be indirectly increased by means of improvement of the communication speed of the outdoor unit, and communication quality is improved.
