摘要： A terminal unit is attached to a monitoring object. The terminal unit locates its position via a position-related signal from a satellite positioning system. The terminal unit acquires first-located position information first, and then second-located position information upon a lapse of a predetermined positioning interval after the first-located position information is acquired. When the first-located position is within a permissible moving zone and the second-located position is outside the permissible moving zone, the terminal unit acquires third-located position information before the predetermine positioning interval lapses. If the third-located position is still outside the permissible moving zone, then the terminal unit sends a reporting signal to a monitor apparatus. The monitor system reduces occurrences of inaccurate reporting signals.
