Abstract

Described is an apparatus and method employing one or more environmental instruments in communication with a communication server that monitors the operation of the environmental instruments based on a task schedule.

Claims

1. An apparatus comprising:

one or more environmental instruments for monitoring water quality for one or more water streams,

a communication server comprising a server monitor,

an alarm transmission server in communication with the communication server, and a server database,

wherein the communication server is in communication with the one or more environmental instruments,

wherein each of the one or more environmental instruments connects to the communication server to report on tasks run by the environmental instrument based on a primary interval for the environmental instrument,

wherein the server monitor continuously queries the server database for tasks that are scheduled to be run by each of the one or more environmental instruments based on a task schedule and a current time on the communication server,

wherein the task schedule is based on the primary intervals for each of the one or more environmental instruments, and

wherein an alarm transmission server of the one or more servers sends an alarm to one or more output devices if the server monitor determines that a selected environmental instrument of the one or more environmental instruments is malfunctioning based on the selected environmental instrument failing to connect to the communication server for one or more primary intervals for the environmental instrument.

2. The apparatus of claim 1, wherein each of the environmental instruments has an alarm trigger value that specifies the number of consecutive times that a respective environmental instrument must fail to connect to the communication server before a missed call alarm is set for the environmental instrument and sent to the one or more output devices.

3. The apparatus of claim 1, wherein the one or more output devices comprise one or more visual display devices.

4. The apparatus of claim 3, wherein the transmission server is in communication with the one or more visual display devices via a web browser.

5. The apparatus of claim 1, wherein the environmental instrument is a logger.

6. The apparatus of claim 1, wherein the environmental instrument is a sampler.

7. The apparatus of claim 1, wherein the one or more environmental instruments are in wireless communication with the communication server.

8. The apparatus of claim 7, wherein the one or more environmental instruments are in wireless communication with the communication server via the Internet.

9. The apparatus of claim 1, wherein when each of the one or more environmental instruments connects to the communication server to report results of a task performed by the environmental instrument, the communication server saves the results of the task and the current time on the communication server to the server database.

10. A method comprising the following steps:

(a) a server monitor of a communication server continuously querying a server database for tasks that are scheduled to be run by each of one or more environmental instruments based on a task schedule and a current time,

(b) an alarm transmission server for sending an alarm to one or more output devices if the server monitor determines that a selected environmental instrument of the one or more environmental instruments is malfunctioning based on the selected environmental instrument failing to connect to the communication server for one or more primary intervals for the environmental instrument,

wherein the alarm transmission server is in communication with the communication server,

wherein the one or more environmental instruments monitor water quality for one or more water streams, and

wherein the task schedule is based on the primary intervals for each of the one or more environmental instruments.

11. The method of claim 10, wherein each of the environmental instruments has an alarm trigger value that specifies the number of consecutive times that a respective environmental instrument must fail to connect to the communication server before a missed call alarm is set for the environmental instrument and sent to the one or more output devices.

12. The method of claim 10, wherein the one or more output devices comprise one or more visual display devices.

13. The method of claim 12, wherein transmission server is in communication with the one or more visual display devices via a web browser.

14. The method of claim 10, wherein the environmental instrument is a logger.

15. The method of claim 11, wherein the environmental instrument is a sampler.

16. The method of claim 10, wherein the one or more environmental instruments are in wireless communication with the communication server.

17. The method of claim 16, wherein the one or more environmental instruments are in wireless communication with the communication server via the Internet.

18. The method of claim 10, comprising the following step:

(c) when each of the one or more environmental instruments connects to the communication server to report results of a task performed by the environmental instrument, the communication server saves the results of the task and the current time on the communication server to the server database.
