High-frequency loop tire pressure monitoring system based on speed sensor

Abstract

The invention discloses a high-frequency loop tire pressure monitoring system based on a speed sensor. The high-frequency loop tire pressure monitoring system based on the speed sensor comprises the wheel speed sensor, an emitting module and a vehicle-mounted BCM; the vehicle-mounted BCM is connected with the wheel speed sensor and the emitting module; the emitting module converts the tire pressure and the temperature information into a high-frequency signal and transmits the high-frequency signal to the vehicle-mounted BCM; the vehicle-mounted BCM receives the high-frequency signal from the emitting module and then sends a feedback signal to the emitting module; the wheel speed sensor collects the tire data forwards, after the data are processed by the BCM, the tire pressure value is figured out, and forward transmission of the feedback signal is conducted. The tire pressure emitting module and the vehicle-mounted BCM are connected jointly to form a feedback loop system through the high-frequency signal and the vehicle-mounted speed sensor. The high-frequency loop tire pressure monitoring system based on the speed sensor has the advantages that 1, signal transmission is more stable, real-time emitting is conducted through a feedback loop, and real-time monitoring during traveling of a vehicle is achieved; 2, the power consumption is greatly reduced and the service life of thesensor is prolonged; and 3, the vehicle-mounted BCM is used for receiving, and the quantity of complex wires and parts on the vehicle is reduced.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a high-frequency loop tire pressure monitoring system based on a speed sensor. Background technique [0002] Tire pressure monitoring is a real-time automatic monitoring of tire pressure during driving, and an alarm for tire leakage and low air pressure to ensure driving safety. Data show that the ratio of car accidents caused by tire blowouts in vicious traffic accidents is as high as 70%, and among all the factors that can cause tire blowouts, insufficient tire pressure is the primary cause. This is not sensational. Even if you do not choose a model with tire pressure monitoring, you should pay more attention to the tires of your vehicle to avoid serious damage to people and cars. [0003] The existing spring pressure monitoring system can only transmit high-frequency unilaterally, and cannot know whether the signal has been received, and there are situations of multiple transmissions or...

Problems solved by technology

[0003] The existing spring pressure monitoring system can only transmit high-frequency unilaterally, and cannot know whether the signal has been received, and there are situations of multiple transmissions or low reception. In order to ensure real-time monitoring of tire pressure, the current technology uses high-frequency acceleration sensors in two cases, and the signal transmission is not stable. Stable, high power consumption
