Abstract

The invention relates to a monitoring terminal (TS), comprising positional information acquisition means (M1S), determination means (AGS-MGS) to provide location information in response to a received signal from a positioning system. Said terminal further comprises calculation means (MCS) to calculate the distance between said position and said location.

Claims

1. A surveillance terminal TS comprising:

reception means MRS of a position information,

determination means AGS-MGS to produce a spot information in response to an reception signal coming from a positioning system, characterized in that it also comprises means MCS to calculate the distance between said position and said spot.

2. The terminal according to claim 1, characterised in that it produces a first warning signal SUS if said distance exceeds a first predetermined threshold, this distance being a first measurement.

3. The terminal according to claim 1, characterized in that it produces a second warning signal SVS if the traveling speed of said position exceeds a second predetermined threshold, this speed being a second measurement.

4. The terminal according to claim 1, characterised in that it produces a third warning signal if the relative traveling speed of said position with respect to said spot exceeds a third predetermined threshold, this speed being a third measurement.

5. The terminal according to claim 2, characterized in that it comprises display means EVS of et least one of said measurements.

6. The terminal according to claim 5 characterized in that, comprising a compass CES, it comprises a slaving module of said display means EVS on said compass CES.

7. The terminal according to claim 1 characterized in that it comprises indicating means EVS of the direction of said position.

8. The terminal according to claim 1, characterized in that, comprising:

reception means MRS-ARS of said position information,

control means MCS to connect said acquisition means M1S and said reception means in response to an activation signal,

it also comprises a co-ordination unit MCS to produce automatically said activation signal.

9. The terminal according to claim 8, characterized in that said activation signal coincides with a predetermined time interval of a repetitive frame synchronized an a clock signal.

10. The terminal according to claim 9, characterized in that it comprises means MRS to position said predetermined time interval in said frame.

11. The terminal according to claim 10, characterized in that, said frame 5 comprising a first subframe consisting of allocated time intervals and a second sub frame consisting of priority time intervals, said predetermined time interval is an allocated time interval.

12. The terminal according to claim 11, characterised in that said subframes are interleaved.

13. The terminal according to claim 9, characterized in that said frame lasts 30 seconds and comprises 30 allocated time intervals of 500 ms and 30 priority time intervals of 500 ms.

14. The terminal according to claim 11 characterised in that it comprises means ARS-MRS, MCS to identify a free allocated time interval.

15. The terminal according to claim 8, characterized in that, said reception signal comprising a synchronization information, it comprises means LGS, CPS, M3S to produce said activation signal in response to said synchronization information.

16. The terminal according to claim 8, characterized in that, additionally receiving an identifying information associated with said position information, said reception means ARS-MRS functioning uninterruptedly, it comprises a memory M3S in which an identification value is stored, said activation signal being produced by said co-ordination unit in the event of a match between said identifying information and said identification value.

17. The terminal according to claim 8 characterised in that, additionally receiving an alarm word associated with said position information, it comprises means MCS to also produce said activation signal in response to this alarm word.

18. The terminal according to claim 17, characterized in that it comprises means to produce a warning signal SUS-SVS in response to said alarm word.
