TRAFFIC SIGNALS FAULT DETECTION SYSTEM

TRAFFIC SIGNALS FAULT DETECTION SYSTEM


FEATURES:

Remote monitoring: intelligent network tech

Traffic signals map (GIS): Google Map, cloud-based services

Services modularization: regional integration remote services

Abnormal alerts: abnormal traffic signals detection

Historical data analysis: lighting information and abnormal records


Detectable faults

  1. The controller has tripped, or a power outage.
  2. The individual lights (one light, one line) has no output (power off).
  3. The red, amber, green lights or green arrow of the traffic signals are not lit (no output).
  4. The count down timer stays at 88.
  5. The count down timer does not display (except manual operating mode).
  6. Green man or red man of pedestrian signals are not lit (no output).
  7. The count-down pedestrian signal dose not display (except manual operating mode).

Application software

  1. Web interface. Do not need to install software, and support Chrome.
  2. Provide user account number and management rights of the interface.
  3. Remote traffic signals monitoring.
  4. Graphical user interface and Google Map can present numbers of traffic signal posts, traffic signals, and types of traffic signal boxes.
  5. Graphical user interface provides weather and traffic flow information.
  6. Provide traffic signal posts and traffic signals information import to the interface, and geographic information system (GIS) of intelligent light import function.
  7. The system switched back on power after the power outage, the parameters will not be erased, and the system operate according to the original settings before the power outage.
  8. Abnormal traffic signals notification (via SMS or E-mail).
  9. Display record chart of abnormal traffic signals.
  10. If the fault detection module fails or is damaged, the traffic signals can be continuously lit by the traffic signal controller to maintain function.
