System OVERVIEW The tire pressure monitoring system (referred as TG for Tire Guard) consists of the following units: - Tire guard transmitter type S122228001 or S122228002 which includes an integrated pressure, temperature and acceleration sensor and a RF transmitter. - RF receiver unit which includes a receiver (not described in this document) The Tire Guard system monitors a vehicle's tire pressure whilst driving or stationary. An electronic unit (wheel unit) inside each tire, mounted to the valve stem, periodically measures the actual tire pressure. By means of RF communication, this pressure information is transmitted to the RF receiver/decoder. In stationary mode, the pressure, temperature and acceleration are measured about every minute and emission of RF frames occurs only if pressure variation, higher than a threshold, is detected (leakage detection). When the vehicle starts moving, the Tire Guard transmitter enters the driving mode. It measures and transmits RF burst 12 times per minute (every 5s) up to 30 bursts. After this period the wheel unit measures and transmits data every minute. The wheel unit will remain in driving mode for a period of 15 minutes after the vehicle is stopped. After this period has elapsed, the wheel unit returns to stationary mode. If, during any measurement period in driving mode, the pressure leakage is detected (difference compared to the last transmitted pressure value), a re- measure will occur after 5s taking in account the latest pressure value emitted as reference value. If the pressure continues changing, an additional transmission will be sent. The circuit within the wheel unit monitors the battery every time a pressure measurement is taken. A “Low Battery” function code will be sent when the battery voltage within the wheel unit is below a pre-selected level.
