  "textContent": "A valve ID registration system includes a sudden pressure decrease detector (31 b) that detects a sudden pressure decrease in the tire and a transmission unit (31c, 32) that transmits a valve signal. When the detector (31b) detects a sudden pressure decrease, the transmission unit transmits the valve signal, which includes sudden pressure decrease information, with more frames than normal. A sudden pressure decrease monitoring unit (4c) monitors the received valve signal for sudden pressure decrease information. After the valve signal including the sudden pressure decrease information is received with more frames than normal, when a new valve signal is received including the same valve ID as that in the valve signal including the sudden pressure decrease information and the new valve signal indicates an increase in air pressure, a registration unit (4f) determines that the valve signals were transmitted from the tire of the vehicle and registers the valve ID.",
