Abstract

The invention discloses a communication method and device of an air conditioner. The method comprises the steps that when a first module and a second module in the air conditioner are in communication, the first module detects the data priority of data to be transmitted, specifically, the data to be transmitted comprise the first data and the second data, and the data priority of the first data is higher than that of the second data; according to the data priority, the first module obtains the first transmitting interval of the first data and the second transmitting interval of the second data, specifically, the first transmitting interval is shorter than the second transmitting interval; and the first module transmits the first data according to the first transmitting interval and transmits the second data according to the second transmitting interval. According to the communication method and device of the air conditioner, the technical problem that due to the fact that all the data are subjected to cycle communication, the communication resource consumption of the air condition is high is solved.

Description

technical field [0001] The present invention relates to the field of air conditioners, in particular to a communication method and device for an air conditioner. Background technique [0002] The communication method between air-conditioning controllers usually uses the Modbus communication protocol for communication. This communication method does not take into account the real-time requirements and communication practicability of communication data. For example, the communication between the display and the main board is performed by the display in a cycle of 4 seconds. Cycle, cyclically send all data frames to the main board. In this communication mode, the communication period is long, the bus data is too much, and the communication resource consumption is large, which reduces the communication processing capability of the air conditioner and causes a certain waste of CPU resources. [0003] For the above problems, no effective solution has been proposed yet. Contents...
