Bluetooth-based tire pressure data transmission method

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.
