Dexdyne has further enhanced Netrix, its popular remote monitoring system, by adding GPRS support.
Dexdyne has further enhanced Netrix, its popular remote monitoring system, by adding GPRS support.
This greatly simplifies the task of adding remote monitoring facilities to industrial plant, and also makes Netrix suitable for many mobile applications.
Netrix is an innovative system that effectively adds web servers to items of plant and equipment, so that managers and engineers can monitor that equipment from wherever they happen to be, simply by using a web browser.
Netrix has applications across a broad range of sectors where people are responsible for managing equipment at a distance: for example, the utilities, facilities maintenance, and in process control.
The wireless GPRS service makes it much simpler to connect items of equipment to the Internet, particularly in remote locations where other communications links (such as regular phone lines) are not readily available.
It is also much more efficient and cost effective to use than traditional dial up systems.
To meet this requirement Dexdyne has made GPRS work in a novel way thought to be an industry first, enabling end users to access any GPRS enabled Netrix unit just as they would a regular website.
Unlike most regular GPRS applications where the mobile end user uses GPRS to access a central webserver that is hardwired to the Internet, Netrix turns the system "back to front".
Now it is the remote plant that is the webserver, connecting wirelessly over GPRS to the Internet, while the end user employs fixed (eg a desktop computer) or mobile connections (eg portable PC or PDA) to access it.
In order for this to function effectively, Dexdyne has launched a special service called the Netrix GPRS Gateway.
This service simplifies the task of managing GPRS enabled Netrix units.
It includes various features designed to optimise performance, to enhance security by eliminating unauthorised accesses, and to enable the consolidation of large numbers of remote units through a single website.
"We have a vast wealth of knowledge regarding remote monitoring, and while many of our industry peers believed that this service could not be made to work in this way using GPRS, it was a challenge we could not refuse", explains Bharat Gupta, Managing Director of Dexdyne.
"It is very satisfying to have achieved what many thought would be impossible".
"GPRS is the perfect replacement for the expensive private radio networks traditionally used for telemetry applications at fixed locations, such as water pumping stations, and we already have several trials of Netrix with GPRS running in the water industry".
"But GPRS also lends itself to a whole host of mobile applications - asset tracking for example", added Gupta "And we are getting more and more enquiries now for this sort of system".
