Method for synchronously displaying Fahrenheit temperature and air conditioning system

Abstract

The invention provides a method for synchronously displaying Fahrenheit temperature. The method comprises the following steps that all display parts receive a centigrade temperature value transmitted by a communication bus; Fahrenheit temperature values corresponding to the received centigrade temperature value are displayed according to the states of a transformation flag bit set in the communication protocol of the communication bus; if the state of the transformation flag bit in the communication protocol is zero, the smaller Fahrenheit temperature value corresponding to the centigrade temperature value is displayed; if the state of the transformation flag bit in the communication protocol is one, the larger Fahrenheit temperature value corresponding to the centigrade temperature value is displayed. The invention further provides an air conditioning system. According to the method for synchronously displaying the Fahrenheit temperature and the air conditioning system, the problem that display is unsynchronized caused by the phenomenon that the same centigrade temperature integral value corresponds to two Fahrenheit temperature integral values is solved; meanwhile, bytes needed by the transformation flag bit which is additionally set in the communication protocol are less, and therefore the expansion of the communication protocol can be conveniently achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a Fahrenheit temperature display synchronization method and an air conditioning system. Background technique [0002] Generally, the wire controller of the air conditioner can set the display mode of the temperature as Celsius or Fahrenheit according to the difference of the sales area. Some air conditioners have the function of dual wire controllers, that is, both wire controllers can control the unit, and the two wire controllers display synchronously. The two wire controllers are synchronized through the communication protocol. Generally, the temperature value is transmitted using the integer value of the Celsius temperature. When converting the temperature from Celsius to Fahrenheit according to the conversion algorithm, there will be a phenomenon that the same integer value of Celsius temperature corresponds to two integer values ​​of Fahrenheit temperature, and th...

Problems solved by technology

When converting the temperature from Celsius to Fahrenheit according to the conversion algorithm, there will be a phenomenon that the same integer value of Celsius temperature corresponds to two integer values ​​of Fahrenheit temperature, and the data sent by the wire controller through the communication protocol is the temperature in Celsius. The other wire controller cannot recognize which of the two Fahrenheit integer values ​​should be displayed, which will cause the two wire controllers to display out of sync

[0003] In view of the above problems, it can be avoided by adding Fahrenheit temperature value data or increasing temperature value decimal data in the communication protocol, but this requires adding more byte data, which is not scalable for some mature communication protocols
