EARTHMOVER TIRE MONITORING SYSTEM

摘要

A system for monitoring earthmover vehicle tires (12), comprising at least one sensor unit (20) mountable within the pressurizable interior of a tire, the sensor unit including a pressure sensor and a temperature sensor, an integrated circuit including memory to collect and store data and to store at least pressure and temperature reference data, a radio frequency interface to transmit received data externally, a magnetic interface for receiving activation, input and deactivation signals, a power circuit, and a microprocessor circuit having a timer for activating pressure and temperature data collection at fixed intervals; a reader (30) mountable on the vehicle remote from the tire, the reader having a receiver for receiving data transmitted from the at least one sensor unit, a memory for storing data received from the at least one sensor unit, and a radio frequency transmitter for transmitting data remote to the vehicle responsive to an external signal; and a portable communication unit (50) comprising a means for communicating with the sensor unit and the reader, a memory for storing data received from the sensor unit and the reader, and a display for displaying received data in visual format.
