Problems solved by technology

[0004] There are two existing solutions: one is integration, which integrates multiple electronic devices and uses one display screen for data display. Although this can effectively simplify the layout of the center console, there is a problem that different electronic devices Manufacturers will obviously not jointly develop an integrated product; the second is to unify the standards for data receiving terminals, and use smart phones and other devices to manage and display data

Embodiment Construction

[0021] The scheme of this application is further described in conjunction with the accompanying drawings as follows:

[0022] A method for transmitting tire pressure data based on bluetooth, comprising

[0023] A. Presetting steps:

[0024] The tire pressure sensor is initialized, and the pairing signal embedded in its ID code is broadcast via Bluetooth;

[0025] The smart terminal starts the pairing mode, searches for and captures the pairing signal, and demodulates the pairing signal in a preset demodulation mode to obtain the ID code of the tire pressure sensor and store it;

[0026] B. The monitoring signal generation steps at the sensing end:

[0027] The tire pressure sensor obtains real-time or intermittently at least the air pressure data of the automobile tires;

[0028] Packing and modulating the air pressure data, and embedding the ID code of the tire pressure sensor, generating a monitoring signal and sending it out;

[0029] C. The signal acquisition and displ...

Abstract

The invention discloses a Bluetooth-based tire pressure data transmission method. The Bluetooth-based tire pressure data transmission method is characterized by comprising the steps of presetting: initializing a tire pressure sensor and broadcasting a matching signal embedded with an ID code of the tire pressure sensor in a Bluetooth manner; starting a matching mode of an intelligent terminal to search and capture the matching signal, demodulating the matching signal in a preset demodulation way, to obtain and store the ID code of the tire pressure sensor; generating a monitoring signal at a sensing end: obtaining data at least including air pressure of automobile tires by the tire pressure sensor in a real-time or intermittent manner; packaging and demodulating the air pressure data, embedding the ID code of the tire pressure sensor, and generating and sending out the monitoring signal; and acquiring and displaying the signal of the intelligent terminal: capturing the monitoring signal, performing demodulation to obtain the ID code; comparing the ID code obtained through demodulation with the stored ID code, if the ID codes are matched, performing further processing and displaying the included air pressure data, or dropping the packet.

Description

technical field [0001] The invention relates to the technical field of tire pressure sensing, in particular to a method for transmitting tire pressure data based on Bluetooth. Background technique [0002] The tire pressure monitoring system (Tire Pressure Monitoring System, TPMS) is a wireless transmission technology that uses a high-sensitivity miniature wireless sensor device fixed in the car tire to collect data such as car tire pressure and temperature while driving or stationary. , and transmit the data to the host computer in the cab, and display relevant data such as tire pressure and temperature in digital form in real time, and remind the driver to give an early warning in the form of buzzer or voice when the tire is abnormal (to prevent tire blowout) automotive active safety systems. The emergence of the tire pressure monitoring system ensures that the pressure and temperature of the tires are maintained within the standard range, which can reduce the probability...
