step 3, automatically matching machine type groups according to the machine numbers;
step 4, selecting a corresponding air pressure set value according to the model;
step 5, comparing and judging the actual air pressure value with a set value and the last measured air pressure value to generate different instructions;
and 106, displaying the air pressure value in different colors or different background colors according to the instruction.
8. The intelligent measurement method for the air pressure of the airplane tire according to claim 7, wherein the step 6 further comprises giving out different warning tones according to the instruction.
9. The intelligent measurement method for the air pressure of the airplane tire according to claim 8, wherein in step 4, five corresponding air pressure set values are selected according to the airplane model.
10. The intelligent measurement method for the air pressure of the airplane tire according to claim 9, wherein in step 5, when the air pressure value of the tire is between the second set value and the first set value, and the first set value is greater than the second set value, the air pressure value of the tire is determined to be normal, and the built-in command 1 is generated;
when the air pressure value of the tire is between a third set value and a second set value, and the second set value is larger than the third set value, judging that the tire needs to be inflated, and generating a built-in command 2;
when the air pressure value of the tire is between a fourth set value and a third set value, the third set value is larger than the fourth set value, the last tire air pressure value is automatically inquired: if the air pressure value is normal, judging that the tire needs to be inflated and monitored, and generating a built-in command 3; if the last air pressure value is smaller than the third set value, the tire is judged to need to be replaced, and a built-in command 4 is generated;
when the air pressure value of the tire is between a fifth set value and a fourth set value, and the fourth set value is larger than the fifth set value, judging that the tire needs to be replaced, and generating a built-in command 5;
when the air pressure value of the tire is lower than a fifth set value, the tire and two tires on the coaxial opposite side are judged to be required to be replaced, and a built-in command 6 is generated;
in step 6, according to the instruction 1, displaying the air pressure value by taking colorless as background color without giving out any prompt tone;
according to the instruction 2, the air pressure value is displayed by taking green as a background color, and three slow prompt tones are given;
according to the instruction 3, if the air pressure value displayed in the system by taking blue as background color is greater than a third set value, three slow prompt tones are emitted;
according to the instruction 4, displaying the air pressure value by taking yellow as a background color, and giving out three-time three-tone prompt sound;
according to the instruction 5, displaying the air pressure value by taking orange as background color, and giving out three-time prompt sound with three sounds;
according to the instruction 6, the air pressure value is displayed by taking red as a background color, and three times of prompt tones with three sounds are given.
