Abstract

A remote water quality monitoring arrangement, a distributed water quality monitoring system with said remote water quality monitoring arrangement, and a method for replacing or installing said remote water quality monitoring arrangement in said distributed water quality monitoring system are provided. The remote water quality monitoring arrangement may include a position detection device, for example a GPS-receiver (Global Positioning System), while a current location of said remote water quality monitoring arrangement is automatically detectable/detected. Water quality measurements, i.e., measurement data, of said remote water quality monitoring arrangement can automatically be assigned with the detected location facilitating a central server—receiving the measurements, i.e., measurement data, together with the detected location of the remote water quality monitoring arrangement—to automatically organize a replacement and/or a new installation of said remote water quality monitoring arrangement in said distributed water quality monitoring system.

Claims

1. A remote water quality monitoring arrangement comprising:

a measuring device configured to measure a physical condition parameter of water and generate measurement data of said measured physical parameter,

a position detection device configured to detect a global position of said remote water quality monitoring arrangement and generate position information of said remote water quality monitoring arrangement, and

a transmitting unit configured to transmit said measurement data together with said position information to a central receiving unit.

2. A remote water quality monitoring arrangement according to claim 1, wherein said measured physical condition parameter of said water comprises one of free or total chlorine, pressure, temperature, turbidity, and conductivity of said water.

3. A remote water quality monitoring arrangement according to claim 1, wherein said measuring device comprises a membrane sensor configured to measure a free or total chlorine residual of said water.

4. A remote water quality monitoring arrangement according to claim 1, wherein said position detection device comprises a GPS receiver configured to detect a current location of said remote water quality monitoring arrangement using a GPS system.

5. A remote water quality monitoring arrangement according to claim 1, wherein said transmitting unit comprises a modem configured to transmit said measurement data together with said position information to said central receiving unit via a GPRS network, and

wherein said modem comprises an identification information identifying said transmitting unit.

6. A remote water quality monitoring arrangement according to claim 1, wherein said transmitting unit is configured to transmit an identification information identifying said remote water quality monitoring arrangement together with said measurement data and said position information to said central receiving unit.

7. A remote water quality monitoring arrangement according to claim 1, wherein said transmitting unit is configured to transmit said measurement data together with a time-stamp of said measurement data to said central receiving unit, wherein said time-stamp is generated by a GPS system.

8. A distributed water quality monitoring system for monitoring a water quality in a water distribution system comprising:

a remote water quality monitoring arrangement arranged at a measuring point in said water distribution system,

a central processing unit comprising;

a central receiving unit configured to receive said measurement data together with said position information from said remote water quality monitoring arrangement arranged in said water distribution system, and

a central monitoring unit configured to provide water quality data to a customer, said water quality data being generated based on said received measurement data.

9. A distributed water quality monitoring system according to claim 8, wherein said central monitoring unit is configured to provide said water quality data in a map-view.

10. A distributed water quality monitoring system according to claim 8, comprising several of said remote water quality monitoring arrangements, each arranged at a different measuring point in said water distribution system, wherein said central receiving unit is configured to receive said measurement data together with said position information from each of said remote water quality monitoring arrangements arranged in said water distribution system.

11. A distributed water quality monitoring system according to claim 8, wherein the system is used for online monitoring of water quality of water of said water distribution system while said central processing unit is accessible via a secure web-based interface from a computer connected to an internet.

12. A method for installing a remote water quality monitoring arrangement in a distributed water quality monitoring system, comprising:

replacing or installing said remote water quality monitoring arrangement at a measuring point in said water distribution system,

said remote water quality monitoring arrangement transmitting identification information identifying said remote water quality monitoring arrangement together with position information of said remote water quality monitoring arrangement to a central receiving unit of said central processing unit, and

said central processing unit identifying said remote water quality monitoring arrangement as a replaced or installed remote water quality monitoring arrangement of said distributed water quality monitoring system.
