STC4012

STC 4012 Traffic Controller is a competitive equipment dedicated to medium size semaphoric plant. The technological characteristics, based on a distributed intelligence realized via a microprocessors network, joint to a customized firmware that allows it to be a peripheral unit suitable for any kind of applications, assures high performances.
As a matter of fact it is able to be, either a peripheral of an UTC system, or a Stand Alone Unit capable of executing an accurate monitoring of its plant with management of :

  • Statistical and Log file archive generation (Traffic data, Emergency and Activities)
  • Automatic remote message dispatch, via GSM or Dial-up telephone line
  • Remote configuration, control and diagnostics access via dial-up telephone line
  • The standard hardware configuration with three serial RS232 communication ports and one RS422/485 port, makes it easy to interface the STC 4012 with various types of communication network and also with other kind of devices.

GENERAL FEATURES

The traffic controller STC4012 can provide the following main functions:

  • Management of a single plant, or of a net of plants, by means of a programmable control algorithm that generates in real time the green times according to the traffic status.
  • Monitoring of all the connected signal-head lamps in order to verify the correct functionality so to signal the burning of a single lamp.
  • Traffic data management, by volume or by class of vehicles, through traditional loop sensors or non invasive sensors such as infrared or microwaves types.
  • Archive of: Traffic data; Alarms; Activities.
  • Automatic alarm messages dispatch to remote sites by means of GSM cellular telephone or by dial up modem and telephone line.
  • Automatic adjustment of the CPU real time clock through a GPS interface, guaranteeing the necessary high precision to realize wireless Green Wave systems.
