Abstract

A remote monitoring system is described which enables monitoring of flow meters or other scientific instruments from a remote location using the GSM cellular phone network. The system includes a wireless modem utilizing the GSM cellular phone network, a central processing unit, connection of a scientific instrument to the central processing unit, power supply (e.g. one or more batteries), and an enclosure for housing the components.

Claims

1. A wireless remote monitoring system comprising:

(a) a wireless modem utilizing a GSM cell phone network;

(b) a central processing unit operatively connected to said wireless modem;

(c) means for connecting a scientific instrument to said central processing unit;

(d) power supply means for providing electrical power to said wireless modem and said central processing unit;

(e) means for automatically changing operating modes of said power supply means by sensing a current used by said wireless modem; and

(f) enclosure means for enclosing said modem and central processing unit.

2. The monitoring system of claim 1, wherein said power supply means comprises at least one battery.

3. The monitoring system of claim 1, further comprising an antenna operatively connected to said wireless modem.

4. The monitoring system of claim 1, wherein said enclosure means comprises first and second housings;

wherein said second housing is adapted to fit within said first housing; and

wherein said wireless modem and said central processing unit are contained within said second housing.

5. The monitoring system of claim 4, wherein said power supply means comprises a plurality of batteries contained within said first housing;

and wherein said batteries are operatively connected to said wireless modem and central processing unit in said second housing.

6. The monitoring system of claim 5, wherein said batteries include upwardly projecting terminals;

and wherein said second housing includes openings enabling said terminals of said batteries to extend through said openings.

7. The monitoring system of claim 4, further comprising an antenna operatively connected to said wireless modem and extending upwardly out of said second housing.

8. The monitoring system of claim 1, wherein said power supply means comprises an external power source.

9. The monitoring system of claim 1, wherein said scientific instrument comprises a flow meter.

10. The monitoring system of claim 1, wherein said scientific instrument comprises a sampler.

11. A wireless remote monitoring system comprising:

(a) a wireless modem utilizing a GSM cell phone network;

(b) antenna means operatively connected to said wireless modem;

(c) a central processing unit operatively connected to said wireless modem;

(d) means for connecting a flow meter to said central processing unit;

(e) power supply means for providing electrical power to said wireless modem and said central processing unit;

(f) enclosure means for enclosing said wireless modem and said central processing unit; and

(g) a modem power supply, which automatically changes operating modes to accommodate both low currents and high currents of said wireless modem, wherein said modem power supply automatically changes operating modes by sensing a current used by said wireless modem.

12. The monitoring system of claim 11, wherein said power supply means comprises at least one battery.

13. The monitoring system of claim 11, wherein said enclosure means comprises first and second housings;

wherein said second housing is adapted to fit within said first housing; and

wherein said wireless modem and said central processing unit are contained within said second housing.

14. The monitoring system of claim 13, wherein said power supply means comprises a plurality of batteries contained within said first housing;

and wherein said batteries are operatively connected to said wireless modem and central processing unit in said second housing.

15. The monitoring system of claim 14, wherein said batteries include upwardly projecting terminals;

and wherein said second housing includes openings enabling said terminals of said batteries to extend through said openings.

16. The monitoring system of claim 11, further comprising a means for automatically changing operating modes of said power supply means by sensing the current used by said wireless modem.

17. A wireless remote monitoring system comprising:

(a) a wireless modem utilizing a GSM cell phone network;

(b) antenna means operatively connected to said wireless modem;

(c) a central processing unit operatively connected to said wireless modem;

(d) means for connecting a sampler to said central processing unit;

(e) power supply means for providing electrical power to said wireless modem and said central processing unit;

(f) enclosure means for enclosing said wireless modem and said central processing unit; and

(g) a modem power supply, which automatically changes operating modes to accommodate both low currents and high currents of said wireless modem, wherein said modem power supply automatically changes operating modes by sensing a current used by said wireless modem.

18. The monitoring system of claim 17, wherein said power supply means comprises at least one battery.

19. The monitoring system of claim 17, wherein said enclosure means comprises first and second housings;

wherein said second housing is adapted to fit within said first housing; and

wherein said wireless modem and said central processing unit are contained within said second housing.

20. The monitoring system of claim 19, wherein said power supply means comprises a plurality of batteries contained within said first housing;

and wherein said batteries are operatively connected to said wireless modem and central processing unit in said second housing.

21. The monitoring system of claim 20, wherein said batteries include upwardly projecting terminals;

and wherein said second housing includes openings enabling said terminals of said batteries to extend through said openings.

22. The monitoring system of claim 17, further comprising a means for automatically changing operating modes of said power supply means by sensing the current used by said wireless modem.
