Embodiment Construction

[0010] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0011] see figure 1 , in an embodiment of the present invention, a high-frequency and low-frequency loop tire pressure monitoring system includes a remote controller, a transmitting module, and a vehicle-mounted BCM. Interaction, the transmitting module activates after receiving the control signal from the remote controller and transmits a low-frequency signal to the vehicle-mounted BCM, and the vehicle-mounted BCM sends a feedback signal to the transmitting m...

Abstract

The invention discloses a tire pressure monitoring system with high frequency and low frequency loops. The tire pressure monitoring system with the high frequency and low frequency loops comprises a remote controller, an emitting module and a vehicle-mounted BCM; the remote controller is connected with the emitting module in a wireless mode; the emitting module and the vehicle-mounted BCM are in information interaction; the emitting module is activated after receiving a control signal of the remote controller and emits a low-frequency signal to the vehicle-mounted BCM; and the vehicle-mountedBCM sends a feedback signal to the emitting module after receiving the low-frequency signal of the emitting module. The tire pressure emitting module and the vehicle-mounted BCM are connected jointlyto form a feedback loop system through the high-frequency signal and the low-frequency signal. The tire pressure monitoring system with the high frequency and low frequency loops has the following 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 a sensor 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 and low-frequency circuit tire pressure monitoring system. 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 at high frequency and unilaterally, and cannot know whether the signal has been received or not. Cause its power consumption to increase, ...
