TPX Energy offers several enabling communications technologies for developing smart grids in both rural and urban areas.

All Access Points act in a similar way; they monitor large amounts of RF based sensor devices in either 433Mhz or 900Mhz frequencies and concentrate that data into a number of outgoing communications modes.

This approach allows our utility clients to choose a number of technologies that would best fit into their existing communications networks.

Once a fault message is sent it is received into Karnack the TPX Energy Distribution Automation Routing Engine. Karnack takes minimal field data, identifies the fault, event, condition and asset description GPS coordinates etc, and then routs the information to the designated GIS, asset or outage management system in a number of protocols.

These protocols include DNP3 serial, DNP3 LAN, Modbus serial, Modbus Plus, TCPIP, ICCP and IEC 61850 protocols.

When used in a smart metering environment Karnack receives data from mete data management systems (MDMS) then identifies and routs the information.

Advanced Metering Infrastructure

TPX Energy is working with a number of leading smart meter and smart meter communications firms on integrating the TPX Energy Distribution Automation platform into their respective technologies.

Cellular / Mobile

TPX Energy Cellular / Mobile Access Points are field programmable state of the art fully self contained multi protocol sensor data concentrators and gateways.  Access Points are available in AC or DC power supply and a 433 or 900 MHz ISM band transceiver.

TPX Energy Access Points come with a universal chassis allowing utility customers to cost effectively upgrade from on spectrum to another when needed. This development has been designed to facilitate upgrades in the field.  

All TPX Energy Access Points are capable of monitoring 80-100 unique Pinpoint RFID sensors simultaneously, in are area covering 40,000 sq meters (125,000 sqft).

The main function of the Access Points is to identify and verify faults and events, compile alarm message then report; location and fault details via SMS message or to a desktop computer instantly.

The Access Points can monitor and report very specific asset details after it has been verified in its internal memory, from its embedded database.

The Access Points range to sensor is determined by sensor signal strength. The pinpoint thermo actuated sensor range is 100-125 meters (328-410 feet) in any single line of sight direction. Or 200-250 meters (656-810 feet) edge to edge
