发明名称 Position monitoring system for a mobile machine
摘要 <p>A system (10) including a mobile machine (20) and a central control station (30) is provided. The mobile machine includes a communication device (70) and a position monitoring system (50) including a receiver (55) configured to receive position data from a positioning satellite (40) and generate a position signal. The position monitoring system also includes an inertial navigation unit (60) including a sensor (61, 62, 63) configured to measure a parameter of the mobile machine and generate a movement signal. The position monitoring system also includes a controller (65) configured to receive the position signal and the movement signal, detect an unavailability of the position signal, calculate a position parameter, determine whether a difference between a first and a second value of a parameter exceeds a predetermined threshold, and generate a warning signal. The central control station is configured to communicate with the controller, receive the position signal and/or the movement signal, and monitor the position of the mobile machine.</p>
