Blank tire pressure detector and setting method thereof

Abstract

The invention discloses a blank tire pressure detector which comprises a shell, wherein one end of the shell is provided with an inflating valve, the other end of the shell is provided with at least one connecting end, and a circuit board is arranged inside the shell. The invention also discloses a setting method of the blank tire pressure detector, which comprises the steps: a first universal output / input end group on the empty tire pressure detector is in telecommunication with a second universal output / input end group on a setting tool through wired connection; and the required communication program is selected by the setting tool and then transmitted into the empty tire pressure detector. The empty tire pressure detector has the following advantages: firstly, the communication programis loaded when the empty tire pressure detector needs to be installed and used, and the version of the communication program can be updated through the network; secondly, the communication program loaded in the tire pressure detector can be stored in a flash memory and cannot be lost due to interruption of power supply; and thirdly, the empty tire pressure detector adopts the design of five connecting ends which are different from common products so that different frequency switching and early warning can be realized.

Description

technical field [0001] The invention relates to the field of automobile tire state detection, in particular to a blank tire pressure detector and a setting method thereof. Background technique [0002] In order to understand the status of the vehicle and ensure driving safety, tire pressure detectors are installed in the tires of the car to detect the tire pressure and temperature and other values ​​for the driver to use as a reference. The control program of the traditional tire pressure detector is directly burned into the detector when it is manufactured. There may be a long period of time between when the product is manufactured and when it is actually installed on the tire. It is possible It is several months. During this period, the program burned into the detector cannot be changed. In other words, if the control program has an updated version later, the tire pressure detector that has been shipped cannot use this new version of the control program. [0003] Another...

AI Technical Summary

Problems solved by technology

First of all, when the user needs to replace the detector to copy the ID, usually the existing detector has been damaged, so that the ID and corresponding data cannot be obtained and copied through wireless communication; moreover, the ROM (Read -Only Memory, read-only memory) is also a problem, because ROM is read-only memory, ID cannot be written into ROM, even if the applicant of the patent mistakenly writes RAM (Random Access Memory, random temporary storage memory) as ROM It is also unworkable, because the data stored in RAM will disappear due to power failure, and the ID in the detector will also disappear due to power failure, making it unusable and unreadable

Therefore, what the above-mentioned patent application discloses is only to rewrite the ID and is an impracticable solution
