In a tire inflation pressure detection device, a receiver functions such that, when an ignition switch is on, power is generated by a power supply controller to set the power supply state of the receiver to one in which frame reception is enabled to detect the inflation pressure of a tire, and such that, when the IG is off, in each predetermined intermittent cycle power is generated by the power supply controller to set the power supply state of the receiver to one in which frame reception is enabled to detect the inflation pressure of the tire. A transmitter determines whether a decrease in tire inflation pressure occurs, and when the decrease occurs, the transmitter transmits frames more frequently than before the occurrence of the decrease in tire inflation pressure at a shorter frame transmission time interval than a regular transmission cycle during a high-frequency transmission period.

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.
