Abstract
The utility model relates to an automatic pressure measuring device for a vehicle tyre, which comprises an air pressure detection chip arranged in the tyre and used for detecting the tyre internal air pressure and an on-board computer connected with the air pressure detection chip in a communication manner, wherein, a tyre normal air pressure value F0 and a threshold value M are stored in the on-board computer, the on-board computer obtains the tyre internal air pressure value F1 detected by the air pressure detection chip, the F0 is compared with the F1, and when the difference value between the F0 and the F1 is more than M, the on-board computer sends out an abnormal prompting message. The automatic pressure measuring device further comprises a warning device, and when the difference value between the F0 and the F1 is more than M, the on-board computer sends out an abnormal prompting message and transmits the abnormal prompting message to the warning device, and the warning device performs warning according to the signal. The utility model has the advantages that the emergency events can be known in advance such as air leakage of the vehicle tyre, tyre burst, and the like, therefore, the possibility of traffic accidents caused by the air leakage and the tyre burst is reduced, and the worry of safety driving of the drivers is reduced.
Description
Technical field
The utility model relates to the motor tire pressure tester.
Background technology
In recent years, along with the continuous decline of vehicle price, domestic increasing people is using automobile.And in the car opertion process, the problem that can not predict in advance is exactly tire gas leakage, blows out, and this also is one makes the very problem of headache of navigating mate.
The utility model content
For the problem that overcomes tyre leakage, blows out and can not predict in advance, the utility model provides a kind of motor tire automatic voltage measurement device.
The wood utility model adopts following technical scheme:
A kind of motor tire automatic voltage measurement device comprises:
Be located at the air pressure detection chip that is used to detect the tire internal gas pressure in the tire;
With described air pressure detection chip communication bonded assembly vehicle-mounted computer, described vehicle-mounted computer stores tire normal barometric pressure value F
0With threshold value M, described vehicle-mounted computer obtains the tire internal gas pressure value F that the air pressure detection chip detects
1, with F
0With F
1Relatively, work as F
0With F
1Difference during greater than M, send abnormal prompt information.
Further, also comprise warning device, work as F
0With F
1Difference during greater than M, described vehicle-mounted computer sends abnormal prompt information and sends a signal to described warning device, described warning device is according to the warning of this signal.
The beneficial effects of the utility model are, accident such as may know tyre leakage in advance, blow out has reduced because of gas leakage, blowing out causes the possibility of traffic accident, has reduced the misgivings of chaufeur trip.
