However, when the car is driving on the road, it can provide the driver and passengers. The important component of comfort and safety is the tire. Since the tire is filled with gas in a rubber ring, it can provide a shock-absorbing effect, thereby providing a comfortable feeling, and the friction between the rubber and the ground is large, so that the friction can force the car to stop for a short time. It provides a sense of security for drivers and passengers. However, if the gas pressure in the tire is too much or too little, it will cause potential danger when the car is running. When the gas pressure in the tire is too high, there is a car running. When the road surface causes a tire puncture crisis, and the gas pressure in the tire is too small. When the car is driving, it will take more power to advance, so that too much unnecessary energy is wasted, and when the vehicle is in an emergency, the brakes cannot be confirmed due to insufficient tire pressure. For tire inflation, most of the workshops in the workshops use a tire pressure gauge to detect the tire pressure and then inflate the tires with an inflator that can be inflated with one hand. Then use the tire pressure gauge to determine whether the tire pressure is sufficient or not. However, for various tire pressures applicable to different types of vehicles, when the maintenance personnel experience is insufficient, it may cause misjudgment when inflating. 3 M423242 The misjudgment of the staff, the actual inspection In view of the above problems, how to reduce the maintenance of the person.

A plurality of preset tire pressure values are built in for the controller 2 to access. In this embodiment, the input and output terminals of the memory module 60 are connected to the input of the controller 2 and the SDA are respectively connected to the controller 2〇. The output terminal pins PT2.2 and PT2.3; a power module 70, mainly composed of a voltage regulator, is used to convert the input power into a stable DC power supply to supply the working power to the aforementioned control M423242 controller 20 and each module, in this embodiment, the power supply 70 is input from a battery to a voltage of 9 volts; - warning 8G, as shown in the lower right of the figure, mainly by a transistor debt test power mode If the 7G battery is about to run out of power, the user can replace the battery immediately. In the embodiment, the base of the transistor Q7 is connected to the wheel-in output pin VDDA of the controller 2, when the power source is When the battery voltage of the module 7 is too low, the control stomach 2 turns off the transistor Q7 through the wheel-in and out terminal VDDA, so that the controller 2 turns into the wheel-out terminal pin A丨5.

The input output terminal of 2() is connected to the pawl 7, and the buzzer BZ1 is connected between the voltages of the collector plate 9 of the transistor ,1, so when the input and output terminals of the controller 20 are connected to the pin ρτ"- The signal causes the transistor Q1 to conduct 'and then the buzzer (2) is energized: the buzzer BZ1 can be alerted as a prompt; a burning seat 21, as shown in the upper right of the figure, is mainly used for borrowing The data is input from the burning seat 21 to refresh the data in the memory module (10), and the burning seat 21 is correspondingly connected to the input wheel output pins VPP, PT1_〇, PT1 of the controller 2(). ", (7) 5, VDD and pm a backlight 15' as shown in the middle of the lower road; mode ... light source enable - compare 2 =:: to provide display interface π Chu display interface, in this implementation 7 M423242 In an example, the backlight 15 is formed by a light-emitting diode (LED) and controlled by an NPN transistor Q2. The base of the crystal Q2 is connected to the input and output pin ρτΐ·5 of the controller 20, so the backlight 15 controls the transistor Q2 through the controller 20, thereby determining the LED of the backlight 15. The illuminating device 40, in the embodiment, the transistors Q5 and Q6 are respectively an NPN-type transistor, and the transistors q3 and q4 are respectively a PNP-type transistor, wherein The bases of the transistors Q5 and Q6 are respectively connected to the input and output terminals ρτ2.5 and PT2.4 of the controller 20, and the collectors are respectively connected to the bases of the transistors Q4 and Q3, and the transistor is respectively connected.
