Wireless programming method for tire pressure detectors
A wireless programming method for tire pressure detectors includes the following steps. A wireless programmer sends an activating command. The tire pressure detectors send a responding message. The wireless programmer receives the responding messages and records identification codes in the received responding messages. The wireless programmer sends a stop-responding command to make the tire pressure detector with the identification codes, which is recorded in the wireless programmer, enter a stop-responding mode. The wireless programmer sends the activating command again. The tire pressure detectors not in the stop-responding mode send the responding messages. The wireless programmer receives the responding message and records the identification code in the received responding message. The wireless programmer sends a code to the tire pressure detectors corresponding to the recorded identification code to program the code. With such design, it could be ensured that the code could be sent and programmed into all the tire pressure detectors.
TIRE DATA COLLECTION AND COMMUNICATION DEVICE, MULTI-PURPOSE HANDHELD DATA COLLECTION AND COMMUNICATION TOOL, AND METHOD FOR COMMUNICATING TIRE DATA BETWEEN A VEHICLE TIRE AND A REMOTE COMPUTING DEVICE
A direct tire data collection and communication device is adapted for use in a pneumatic vehicle tire. The device incorporates a tire-mounted electronics module comprising a microcontroller, and at least one tire property sensor in electronic communication with the microcontroller and capable of measuring at least one operational property of the vehicle tire. The threshold operational property value defines a positive tire safety condition and a negative tire safety condition. The electronics module calculates accumulated travel data of the vehicle tire while in the negative tire safety condition. A transmitter transmits the travel data to an electronic remote terminal.
