Abstract

A system for the monitoring of remote equipment or processes such as oil and gas wells. The system utilizes a local controller at each site which transmits data to a central server over a wide area network. Preferably, the local controller will be connected to the wide area network via a wireless radio frequency connection. The central server then provides the stored data to users via served web pages or custom software viewable on any compatible computer attached to the network. The users of the system can also enter data values into web pages on the viewing computer to be transferred through the system to the local controller to alter its operation or that of the equipment to which it is attached.

Claims

1. A system for the remote monitoring of equipment, said system comprising:

(a) a central server having non-volatile storage capability;

(b) at least one local controller having at least one data connection to the equipment being monitored and in data communication with said central server, said data communication comprising bi-directional data transmission via a general purpose wide area network;

(c) at least one end user computer in data communication with said central server, said data communication comprising data transmission via a general purpose wide area network;

(d) wherein said local controller periodically transmits data to said central server via said data communication and said data is stored by said central server using said non-volatile storage capability.

2. The monitoring system of claim 1 wherein said data communication between said local controller and said central server comprises a wireless, full-duplex connection.

3. The monitoring system of claim 2 wherein said wireless connection is interposed between said local controller and said wide area network and wherein said local controller is addressable as a device on said wide area network.

4. The monitoring system of claim 1 wherein said local controller further comprises non-volatile storage and said local controller caches said data in said storage in the event that said data communication with said server is unavailable at the time of said periodic transmission.

5. The monitoring system of claim 4 wherein said local controller automatically transmits said cached data as a part of the next of said periodic transmissions at which said data communication is available.

6. The monitoring system of claim 1 wherein said local controller is responsive to at least one control parameter and wherein said control parameter can be modified by said end user computer.

7. The monitoring system of claim 6 wherein said modification of said control parameter comprises transmission of a modified value from said end user computer to said central server and retransmission of said modified value from said central server to said local controller.

8. The monitoring system of claim 1 further comprising a pre-loaded display program executing on said end user computer, said display program comprising plural graphical display components responsive to data values retrieved at a later time from among those stored by said central server.

9. A system for the remote monitoring of equipment, said system comprising:

(a) a web server software application providing data storage, data retrieval and web page serving services;

(b) at least one local controller client, communicating with said web server, adapted to retrieve monitor data from the monitored equipment and to transmit said data to said web server for storage;

(c) at least one display client, communicating with said web server, adapted to retrieve said monitor data from said web server and display it visually.

10. The monitoring system of claim 9 wherein said local controller client and said display client each comprises a different software application executing on a different general purpose computer.

11. The monitoring system of claim 10 wherein at least one of said data communication between said local controller client and said web server and between said display client and said web server comprises retrieval of a web page comprising an embedded executable object which interacts with said web server data storage.

12. The monitoring system of claim 9 wherein said local controller client is further adapted to temporarily cache said monitor data when unable to communicate with said web server immediately after retrieving said monitor data.

13. The monitoring system of claim 12 wherein said local controller client automatically transmits said cached monitor data when again able to communicate with said web server.

14. The monitoring system of claim 9 wherein said local controller client is responsive to at least one control parameter and wherein said display client is further adapted to retrieve, modify, and store said control parameter.

15. The monitoring system of claim 9 wherein said local controller communicates with said web server via a general purpose wide area network and said display client communicates with said web server via the same said general purpose wide area network.

16. The monitoring system of claim 15 wherein said local controller client further communicates with said web server via a wireless radio frequency connection interposed between said local controller and said general purpose wide area network.

17. The monitoring system of claim 16 wherein said local controller client is directly addressable as a device on said general purpose wide area network.

18. The monitoring system of claim 9 further comprising an authentication server in communication with said web server and said display client, adapted to authenticate access of said monitor data, stored by said web server, by said display client.

19. The monitoring system of claim 18 further comprising a security server in communication with said web server and said display client to validate access by said display client to the services of said web server.
