Abstract

The invention relates to a surveillance system wherein a localisation terminal TL and a surveillance terminal cooperate. Each terminal TL comprises: means for the acquisition M1L of a localisation message; communication means MRL-ARL; and control means MCL for connecting the acquisition means and the communication means in response to an activation signal. Said terminal also comprises a co-ordination body MCL for automatically producing the activation signal, the control means being activated if, and only if, the activation signal is present.

Claims

1. A terminal TL, TS comprising:

acquisition means R1L, M1S of a locating message,

communication means MRL-ARL, MRS-ARS,

control means MCL, MCS to connect said acquisition means and said communication means in response to an activation signal, characterised in that it also comprises a co-ordination unit MCL, MCS to automatically produce said activation signal, said control means being activated if and only if said activation signal is present.

2. The terminal according to claim 1, characterized in that said activation signal coincides with a predetermined time interval of a repetitive frame synchronised on a clock signal.

3. The terminal according to claim 2, characterized in that it comprises means BRL, MRS to position said predetermined time interval in said frame.

4. The terminal according to claim 2, characterised in that, said frame comprising a first subframe consisting of allocated time intervals and a second subframe consisting of priority time intervals, said predetermined time interval is an allocated time interval.

5. The terminal according to claim 4, characterised in that said subframes are interleaved.

6. The terminal according to claim 2, characterised in that said frame lasts 30 seconds and comprises 30 allocated time intervals of 500 ms and priority time intervals of 500 ms.

7. A locating terminal TL according to claim 1, characterised in that:

said acquisition means R1L come after spotting means AGL-MGL which receive a reception signal coming from a positioning system, and in that

said communication means are radio transmission means MRL-ARL.

8. The terminal according to claim 7, characterised in that said locating message comprises information relating to the position of said terminal TL.

9. The terminal according to claim 7, characterised in that said locating message comprises information relating to the identification of said terminal TL.

10. The terminal according to claim 7, characterised in that, said reception signal comprising a synchronisation information, it comprises means LGL, CPL, R3L to produce said activation signal in response to said synchronisation information.

11. The locating terminal according to claim 4, characterised in that,

said acquisition means R1L coming after spotting means AGL-MGL which receive a reception signal coming from a positioning system, and

said communication means being radio transmission means MRL-ARL,

it comprises means MCL, R4L to also produce, in response to an alarm signal, said activation signal at least in the nth priority time interval following the occurrence of said alarm signal, n being a predetermined number, and in that

it comprises means MCL to introduce an alarm word into said locating message.

12. The terminal according to claim 11, characterised in that it comprises means to repeat said alarm word in the first allocated time interval which follows said nth priority time interval.

13. The terminal according to claim 11, characterised in that said alarm signal originates from an immersion detector DIL.

14. The terminal according to claim 11, characterised in that said alarm signal originates from an emergency button BUL.

15. The terminal according to claim 11, characterised in that said alarm signal originates from a shock detector CDL.

16. A surveillance terminal TS according to claim 1, characterised in that

said acquisition means consist of a memory M1S, and

said communication means are reception means ARS-MRS.

17. The terminal according to claim 16 characterised in that, said locating message comprising an identifying information, said reception means ARS-MRS functioning uninterruptedly, it comprises another 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.

18. The surveillance terminal TS according to claim 2, characterised in that:

said acquisition means consist of a memory M1S, and

said communication means are reception means ARS-MRS.

19. The terminal according to claim 16, characterised in that it comprises determination means AGS-MGS to produce a situation message in response to a reception signal coming from a positioning system.

20. The terminal according to claim 19 characterised in that, said reception signal comprising a synchronisation information, it comprises means LGS, CPS, M3S to produce said activation signal in response to said synchronisation information.

21. The terminal according to claim 19, characterised in that, said locating message comprising a position information, said situation message comprising a spot information, it comprises means MCS to calculate the distance between said position and said spot.

22. The terminal according to claim 21, characterised in that it produces a warning signal SUS if said distance exceeds a first predetermined threshold, this distance being a first measurement.

23. The terminal according to claim 21, characterised in that it produces a warning signal SVS if the traveling speed of said position exceeds a second predetermined threshold, this speed being a second measurement.

24. The terminal according to claim 22, characterised in that it comprises display means EVS of said measurement.

25. The terminal according to claim 24, characterised in that, comprising a compass CES, it comprises a slaving module of said display means EVS on said compass CES.

26. The terminal according to claim 21, characterised in that it comprises indicating means EVS of the direction of said position.

27. The surveillance terminal TS according to claim 4, characterised in that:

said acquisition means consisting of a memory M1S, said

said communication means being reception means ARS-MRS,

said locating message comprising an alarm word,

it comprises means MCS to also produce said activation signal response to this alarm word.

28. The terminal according to claim 27, characterised in that it comprises means to produce a warning signal SUS-SVS in response to said alarm word.

29. The terminal according to claim 4, characterised in that:

said acquisition means consisting of a memory M1S, and

said communication means being reception means ARS-MRS,

it comprises means ARS-MRS, MCS to identify a free allocated time interval.
