You need a controller with a binary output that can be remotely switched. In the old days we used phone modems for the connection, but nowadays a TCP/IP connection is the thing.

You could use two way radios with selcall or data modems. Easy to do though you will need to do your homework.

Temora Shire Council in Australia, utilises their trunking radio network for just that purpose. It also reports back information on tank levels etc.

They cover many hundreds of square kilometers.

Hello,

Do you gave GSM network present in that area.

I can supply one GSM controlled remote pump controller

We have designed and are currently supplying RTU's and SCADA software for central control room for approx 800 water filtration plants. The filtration plants are being built by KSB Pumps and we are their SCADA sub-contractor and our scope of work includes complete software/hardware design, development, manufacturing and project startup. Each RTU has a GSM modem and the system we have designed supports two way communication/control over GSM network.

Let me know if this interests you.

thanks

I AM VERY MUCH INTERESTED.PLEASE GIVE MORE INFORMATION .

Here is the synopsis of the project:

1. The project is to install 800 standalone water filter plants over a wide geography with raw/utility water as input and highly filtered potable water as output.
2. Our part in the project is three components, a). The plant controller hardware design & implementation, b). The plant controller software, and c). The SCADA services thereof.
3. For the hardware, we are using a small Linux based controller with 16 digital inputs and 8 digital outputs. We program this controller in C for the plant control logic.
4. We use a GSM based GPRS-capable modem attached to one of the serial ports of the controller, to serve as SCADA communication device.
5. The central control room (under design at the moment) shall be a network of linux-based workstations, equipped with a communication hub comprising of 16-32 GPRS modems connected via ethernet gateways to a central control network (TCP/IP over ethernet).
6. We are implementing a custom designed, high reliability (redundant) messaging database which shall be responsible for handling all the incoming messages from plant sites and issuing command messages to these plant sites.
7. The graphical user interfaces shall be built on top of X-Windows graphical display system and programmed in C.
8. The messaging is designed primarily over SMS with GPRS capabilities used as backup.

Hope this provides you some idea. Send me an e-mail on qskhan@gmail.com should there be any interest.

Thanks,
