Device for interface between the peripheral equipment and the traffic control centre

                        

Application:

Connection between the main control centre of the automated system for control of city road traffic and the peripheral control equipment over GSM/GPRS cellular networks.

 

Provides:

Transmission of the following information from the Spektr1 radar vehicle detector to the main control centre:
• - presence (number) of moving vehicles in up to 8 control zones (this information is used to calculate intensity pulses for each zone);
• - statistics related to traffic flow dynamics (option), including the following parameters:
• - total number of vehicles passing through a control zone;
• - occupancy of a control zone (ratio of the time during which a zone is occupied by a vehicle to the time of statistical registration);
• - mean speed of the traffic flow passing through a control zone;
• - number of long-length vehicles (more than 10 m long) passing through a control zone.

An RS-485 interface adapter (option) incorporated in the device makes it possible to control the following equipment:
• - advance information boards;
• - speed indicators (sign 5.18.1);
• - remotely-controlled signs, etc.

A built-in accumulation battery provides round-the-clock operation of the device and the vehicle detector in any season (with power supply from the lighting network).

 

Basic characteristics:
• - operating temperature range: from -40°С to +50°С with relative humidity of (98±2)% at 35°С;
• - mains nominal voltage: 230 V at 50 Hz;
• - cabinet dimensions: 200х300х150 mm;
• - the device can be accommodated on lamp posts with a diameter of 70 to 140 mm.
