DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0018] Referring to FIGS. 1 and 2, the programming system of the present invention comprises a programming tool 1 and a tire pressure monitoring sensor 2. The programming tool 1 includes a control panel 11 for the users to operate the programming tool 1. The programming tool 1 has a central processor 12, a program database 13, a first wireless transmission module 14 and a verification code issuing module 15 built therein. The program database 13, the first wireless transmission module 14 and the verification code issuing module 15 are electrically connected to the central processor 12. The central processor 12 is electrically connected to the control panel 11. The verification code issuing module 15 issues a verification code by the first wireless transmission module 14. The tire pressure monitoring sensor 2 includes a signal processor 21 which is electrically connected to a program storage module 22, a verification code receiving module 23, a feed-back module 24 and a second wireless transmission module 25. The verification code receiving module 23 includes a pre-set verification code 231. When the verification code received by the verification code receiving module 23 is equal to the pre-set verification code 231, the feed-back module 24 issues an installation code to the first wireless transmission module 14 of the programming tool 1 by the second wireless transmission module 25.

[0019] The program database 12 stores programs of the compatible tire pressure monitoring sensor of different models and vehicle brands.

[0020] The power supply of the programming tool 1 can be a disposable battery, a rechargeable battery, or an external power supply.

[0021] The central processor 12 processes and transfers signals and programs between the electrically connected components.

[0022] The signal processor 21 processes signals and programs between the electrically connected components.

[0023] As shown in FIG. 3, the method of programming for a tire pressure monitoring sensor comprises the following steps:

[0024] step 1: operating a programming tool 1 that is compatible to a tire pressure monitoring sensor;

[0025] Step 2: setting the programming tool 1 to an auto programming mode;

[0026] step 3: the programming tool 1 issuing a verification code by a first wireless transmission module 14 and a verification code issuing module 15;

[0027] step 4: the tire pressure monitoring sensor 2 including a verification code receiving module 23 which is cooperated with a second wireless transmission module 25 to receive the verification code, assuming that the verification code received by the tire pressure monitoring sensor 2 is different from a pre-set verification code 231 of the tire pressure monitoring sensor 2, proceed to a step 5A; assuming that the verification code received by the tire pressure monitoring sensor 2 is equal to the pre-set verification code 231 of the tire pressure monitoring sensor 2, proceed to a step 5B;

[0028] step 5A: assuming that the programming tool 1 issues the verification code and does not receive a feed-back signal for a period of waiting time (5 seconds, for example) from the tire pressure monitoring sensor 2, the programming tool 1 issues another verification code; assuming that the verification code received by the tire pressure monitoring sensor 2 is different from the pre-set verification code 231 of the tire pressure monitoring sensor 2, proceed to the step 5A; assuming that the verification code received by the tire pressure monitoring sensor 2 is equal to the pre-set verification code 231 of the tire pressure monitoring sensor 2, proceed to the step 5B, and

[0029] step 5B: the tire pressure monitoring sensor 2 issuing an installation code by the feed-back module 24 via the second wireless transmission module 25 to the first wireless transmission module 14 of the programming tool 1, the programming tool 1 using the central processor 12 to compare an installation code to the programs in the program database 13 and installing programs corresponding to the installation code to a program storage module 22 of the tire pressure monitoring sensor 2; the step 1 and the step 2 being exchangeable.

[0030] Consumers simply purchase after-market tire pressure monitoring sensor from different manufacturers and the after-market tire pressure monitoring sensor are compatible to the programming tool 1, the staff of the repair shop can use the automatic programming mode of the programming tool 1 to quickly install the programs of the corresponding manufacturer to the tire pressure monitoring sensor. For example, the consumer purchases a tire pressure monitoring sensor 2 of model A of brand A, and it is compatible to the list built in the programming tool 1, then the programming tool 1 can automatically program the tire pressure monitoring sensor 2 with the programs of the model A of the brand A by the automatic programming mode.

[0031] It is noted that, even if the tire pressure monitoring sensor 2 with the verification code of the model A of the brand A, not only the tire pressure monitoring sensor 2 can program the model A of the brand A, the programming tool 1 can still program other model of other brands manually.

[0032] The transmission way of the first wireless transmission module 14 and the second wireless transmission module 25 is Low Frequency (LF), Radio Frequency (RF) or Bluetooth so as to meet the transmission frequency and transmission way of the existed tire pressure monitoring sensors.

[0033] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
