According to an embodiment of the application, a method for encoding infrared signals of a remote controller is provided.
Fig. 1 is a flowchart of a method for encoding infrared signals of a remote controller according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
step S101, relevant parameters of an electric appliance remotely controlled by a remote controller are obtained, and the relevant parameters are used for representing the working state of the electric appliance;
specifically, the electrical appliance may be an air conditioner, a television, or the like.
Specifically, the relevant parameters may be temperature, humidity, wind speed, wind sweeping angle, and the like.
Step S102, acquiring the number of the values of the relevant parameters;
and S103, determining that the encoding mode for encoding the infrared signals sent by the remote controller is an N-system encoding mode according to the number of the values of the related parameters, wherein N is more than or equal to 2.
For example, when the relevant parameter is temperature and the wind sweeping angle, the temperature takes the following values: 15. 17, 19, 21, 23, 25, 27, 29. Namely, the number of values of the temperature is 8, and the value of the wind sweeping angle is as follows: 20. 30, 40, 50, 60, 70, 80, 90, 100. Namely, the number of values of the wind sweeping angle is 9. At this time, the infrared signal sent by the remote controller can be coded by adopting a decimal coding mode, 10 is more than 9, namely each wind sweeping angle can correspond to a decimal number, for example, 1 corresponds to 20,2 to 30,3 to 40,4 to 50,5 to 60,6 to 70,7 to 80,8 to 90,9 to 100, namely, one digit is adopted to realize the coding of 9 wind sweeping angles, and if the binary codes are adopted for 9 wind sweeping angles, "0000" to "1001" are needed, namely, the decimal coding is adopted to ensure that the number of code sending digits is less, namely the decimal number is shorter than a binary code sending information packet, and further the time for code sending is shortened.
In the scheme, the number of the values of the relevant parameters is obtained by obtaining the relevant parameters of the electric appliance remotely controlled by the remote controller, and then the coding mode for coding the infrared signals sent by the remote controller is determined to be an N-system coding mode according to the number of the values of the relevant parameters, namely the N size is determined according to the number of the values of the relevant parameters, so that the number of code sending bits is small, the code sending information packet is short, the response of the electric appliance is quick, and a binary coding mode is not adopted indiscriminately.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than presented herein.
In an embodiment of the present application, determining, according to the number of the values of the relevant parameter, that the encoding mode for encoding the infrared signal sent by the remote controller is an N-ary encoding mode, includes: determining a target parameter of the plurality of relevant parameters, wherein the target parameter is the relevant parameter with the largest number of values in the plurality of relevant parameters; and determining that the number of the values of the target parameters is less than or equal to N.

For example, the values of the sweep angle are: 20 °, 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, 90 °, 100 °. It is determined that 20 ° corresponds to the decimal number 1, 30 ° corresponds to the decimal number 2, 40 ° corresponds to the decimal number 3, 50 ° corresponds to the decimal number 4, 60 ° corresponds to the decimal number 5, 70 ° corresponds to the decimal number 6, 80 ° corresponds to the decimal number 7, 90 ° corresponds to the decimal number 8, and 100 ° corresponds to the decimal number 9. Each decimal number corresponds to a mid-infrared signal, which may be, in particular, a voltage waveform.
In another embodiment of the present application, the determining the infrared signal corresponding to each N-ary number, where the infrared signal includes first half frame data and second half frame data, includes: determining the high-level time width and the low-level time width of the first half frame data corresponding to each N-ary system number; and determining the high-level time width and the low-level time width of the second half frame data corresponding to the N-ary numbers. Namely, the infrared signals corresponding to different N-system numbers are distinguished according to the high-level time width and the low-level time width.
Specifically, the format of each frame of data is a pilot code + first half frame data + half bit end bit +20ms low level + second half frame data + check bit + half bit end bit; the interval between each frame of data is 40ms.
In a specific embodiment of the present application, the electrical appliance is an air conditioner, the related parameter includes a temperature, and determining an N-ary number corresponding to each value of the related parameter includes: determining the N-system number corresponding to a first preset temperature value of the air conditioner in a refrigeration mode as a first N-system number; and determining the N-system number corresponding to a second preset temperature value of the air conditioner in the heating mode as a second N-system number. That is, when the controlled temperature value is the same, it is necessary to distinguish between the cooling mode and the heating mode.
