• No need for cabling - solar power supported; multiple wireless interfaces supported (3G, GPRS, GSM, Bluetooth, radio modem, WiFi)
FULL CONTROL OVER YOUR SYSTEM LOCALLY
• Enables full local control over system modules - access point to end units which are usually not easy to approach (on the gantry, inaccessible by terrain, on pole, …)
• Facilitates system maintenance - point of control in the system
SIMPLE TO MAINTAIN
• Quick plug & play module replacement - less than 2 minutes
• Minimum number of different spare parts interchangeable between all Telegra controllers
• Spare parts interchangeable with other Telegra ATMS equipment
ADDED VALUE TO YOUR SYSTEM WHEN INTEGRATED IN ATMS THROUGH topXview™
• Increases safety - executes safety algorithms based on traffic, meteorological and incident detection data
• Eliminates unnecessary costs - provides common interface for all field elements of ATMS
GENERAL
The roadside controller (RC) has a basic function of being a communication concentrator for field ATMS devices. RC is built as a concentrator capable to control any function group of field equipment.
Roadside controller is an element of traffic system which, upon request from control centre, controls executive devices situated by the road (variable message signs, barriers, traffic lights, etc.) and collects data from various sensors belonging to traffic system (weather sensors, vehicle detectors etc.), which are relevant for traffic management. Roadside controller processes data, aggregates it and sends it to the control centre. In case of communication breakdown with control centre, installed software takes over control over traffic equipment on the corresponding road section and manages it by pre-programmed algorithms.
Roadside controller can also be delivered as fully compliant TLS (German recommendation for roadside controllers) unit.
When working as a traffic counter, RC collects traffic data, processes it and stores it into a large non-volatile memory buffer (SD Flash memory card).
Traffic data can then be gathered locally (by replacing the memory card) or can be downloaded (e.g. using GSM modem, laptop, etc.). When integrated with other tunnel or roadside subsystems, RC provides cross links between traffic management equipment and other subsystems (automatic incident detection, PLC system, fire detection …). Cross links on local level enable fast system responses to any kind of incident, especially important in cases of communication break-down with main control centre.
