Problems solved by technology

However, most tire pressure monitoring systems currently on the market are mainly based on active sensing, that is, the tire pressure acquisition module needs to be powered by a separate power supply. This measurement system is divided into tire internal transmitters and tire external receivers. During use There are many problems

Abstract

The invention discloses a vehicle-mounted real-time tire pressure monitoring device, which comprises a sensor, a signal collection module, a frequency conversion module, a central processing module and a display module, wherein the sensor comprises two metal rings which are axially oppositely arranged, and a piezoelectric ceramic ring is arranged between the two metal rings; the outer diameter of the piezoelectric ceramic ring is equal to that of each metal ring; an electrode ring sheet is arranged between each of two axial ends of the piezoelectric ceramic ring and the corresponding metal ring; the sensor is connected with the signal collection module, the frequency conversion module, the central processing module and the display module in sequence; the frequency conversion module is composed of a power amplifier, a primary filter, a low frequency amplifier, a frequency mixer, a secondary filter and a medium frequency amplifier; the power amplifier is connected with the signal collection module; the medium frequency amplifier is connected with the central processing module. The vehicle-mounted real-time tire pressure monitoring device is good in sealing effect, high in measuring precision and stable in data measuring; a traffic accident is avoided and no environment pollution is caused.

Description

technical field [0001] The invention relates to a tire pressure monitoring device, in particular to a vehicle-mounted tire pressure real-time monitoring device. Background technique [0002] With the development of society and the popularization of vehicles, the safety of automobiles has attracted more and more attention. Among the many potential safety hazards, the hidden dangers of tires account for a large proportion, especially for vehicles running at high speed on expressways. The suddenness of the tire blowout makes the driver difficult to control the driving direction and the traffic accidents caused account for about 48% of the total accidents. If the tire pressure is outside the standard tire pressure range or when the tire pressure is abnormal, the alarm can be issued in time, Just can effectively avoid the traffic accident that causes because of tire factor. Therefore, the tire pressure monitoring system came into being. Because it can actively provide the dr...
