Road traffic signal controller

product description

Functional characteristics

  1. The traffic signal output of the signal machine adopts the phase system, which can provide a maximum of 72 traffic signal outputs, and the load of each channel is not greater than 5A; the standard configuration is 48 channels of output;
  2. Provide a hardware yellow flashing mechanism to take over the signal when the main control unit works abnormally, and output a yellow flashing signal to the signal light;
  3. With signal lamp short-circuit and open-circuit detection, it can stably detect signal lamp failures, and record fault phenomena and time of failure, and downgrade according to a predetermined plan;
  4. Provide manual control of stepping, four-sided red, yellow flashing, light off, next phase, next direction switch, etc., you can switch to the corresponding state directly through the switch;
  5. The traffic signal has 8-way pedestrian button input to realize the pedestrian self-service mode, and it can also realize the function of one-street and two-street crossing;
  6. The signal machine has a multi-period signal control function, and it has a variety of different period priority control including holidays, Saturdays and Sundays;
  7. The signal machine has an induction control function, which can adjust the traffic signal output through the vehicle signal input by the detector, which can be divided into half induction and full induction;
  8. The signal machine has a cable-free coordination function, which can automatically adjust the phase time according to the phase difference (green band coordination);
  9. The signal machine has an adaptive control function, which can adjust and optimize the green signal ratio of the signal according to a certain algorithm;
  10. The semaphore has the function of networking, and the function of downgrading the network;
  11. The signal machine has an active countdown data output function, which is output through the 485 interface;
  12. The lamp control output switch device is equipped with a fuse to prevent lightning surge overvoltage and overcurrent protection.
  13. Support SD card to store traffic flow data and device logs. SD card can also be used as the media for system software installation and upgrade;
  14. Supports data storage and printing functions via USB;
  15. Support the configuration of vehicle inspection board and vehicle inspection interface board, so that the signal machine has the function of vehicle traffic detection and storage;
