RTU Remote Telemetry Units Monitored using the Internet
Next month Introducing ZigBee Mesh Networks
RTU devices at small sites benefit from Internet based monitoring via the wireless GPRS network to eliminate onsite costly PC and associated software.
An RTU is a Remote Telemetry Unit that monitors the status of equipment such as air conditioning, temperature, door open/closed, or energy consumption. Each RTU is wired or wirelessly connected to an onsite PC, which provides SCADA management capabilities. Although this may suit large buildings and factories, it is not cost effective for managing small sites with single or low numbers of equipment.
RTU/SCADA polling systems do not suit the GPRS network and the Internet!
With 1 modem connection it could take 1-2 weeks to gather the data!
Traditionally, the problem is solved by enabling the PC to poll every device over a modem connection. However, this isn't ideal for client driven networks and has some key issues: -
- Bottlenecks where the PC communicates sequentially with remote units
- Proprietary protocols make it difficult to interoperate with 3rd parties
- Costly Infrastructure due to the private networking nature of the solution
- Not scalable for large numbers of devices with a reliable and robust network communication
Web-based SCADA and RTU solutions are cost effective and scalable
"IP Push Technologies" overcome polling bottlenecks and allow simultaneous connections to offer true real-time data.
