DC Wireless Traffic Signal

DC Wireless Traffic Signal, Solar Wireless Traffic Signal, AC Wireless Networked Traffic Signal

Offering comprehensive signal transmission solutions tailored to the unique requirements of various application scenarios.

1. Basic Functions

(1) Equipped with various control modes and multiple time-slot options, including yellow flash and off modes.

(2) Traffic Control

(3) Yellow Flash Control

(4) Fixed Period Control

(5) Command Center Stepping Control

(6) Manual Control: Signal conversion and amber flash control are performed manually; the signal unit supports remote manual control.

(7) Local Mode Standard Schedule Control: This mode is the basic control method for signal machines. In this mode, the design is offline and stored in the intersection machine. Input schedules into the intersection machine and select execution plans based on the schedules. Time periods include year, month, week, day, hour, minute, and second. The division of daily periods should not be less than 16, and the number of plans should not be fewer than 48. The settings should include events, control modes, control plans, holiday plans, etc.

2. Network Control Function

The wireless signal transmitters can be connected to the control platform via the Internet of Things, enabling unified control and security management.

3. Green wave control function

The signal machine can be synchronized with the mainline signal machine using GPS/Beidou or a server, ensuring consistent cycles while coordinating phase differences in the mainline direction to achieve green wave control functionality.

4. Schedule Control Function

The signal machine can divide a day into time slots based on a specified date or week number, execute different timing plans for each slot, and carry out the plans in the order of time slots.

5. Manual Control Feature

In an online condition, the central staff will switch the intersection signal machine to the designated phase. On-site at the intersection, the signal machine can be immediately executed to the designated phase through a manual control panel.

6. Wireless Remote Control Function

In the event of communication failure or during emergencies, the on-board remote controller or the patrol remote controller at intersections can be used to directly switch the signal machine to the designated phase.

7. Yellow flash, full red, and light-off control function

In special circumstances requiring closure, such as red light failure, the need for warning, or accidents, flashing yellow, full red, or light-off control may be implemented.

8. Fault Alarm Function

When the voltage drops below 10.5V or power is disconnected, a power failure alert can be triggered via SMS messages on the phone.

9. Green Conflict Detection Feature

When a red and green light failure occurs in the same group of lights, the affected master/slave unit(s) have a power-off function, while other master/slave units will degrade to yellow flashing to avoid vehicle driving conflicts caused by signal light failure.

10. Guard patrol route setting feature supported

Users can configure multiple guard routes in the control center. The signal system can receive and store various guard and special operations plans, providing quick access routes for guard vehicle fleets and other special operations vehicles (such as fire trucks, emergency ambulances, and engineering rescue vehicles).

11. Personnel Special Duty Control

The system will pre-store special operation plans for intersections on the special operation control lines within each signal post. When a convoy approaches the corresponding intersection on the special operation line, the on-duty police officer at the intersection notifies the duty officer at the center, who then manually executes or cancels the special operation plan for that intersection.
