The present invention inputs the required power and signals using the signal lines of the existing traffic lights, and supplies the necessary power to the traffic signal display device, and automatically stores the technology and arbitrary signal states stored in the power backup device in consideration of power failure. Detects and stores the signal holding time, displays the traffic signal in the form of time and direction to the driver and pedestrian, and displays the traffic signal according to previously stored traffic flow information and current display time in case of power failure It is a traffic signal display device having a function of matching with a traffic signal that is turned on and off by feeding back the feedback.

Conventionally, a stop, a direction, a progress display of a traffic light, a stop and a pedestrian display of a pedestrian, or a remaining time display device while walking are installed and operated. In this way, a sudden change of signal to a driver or a pedestrian, psychological anxiety in a waiting state, and a sudden start and stop of a driver may prevent smooth traffic and a traffic accident may occur.

Technical problem applied to the present invention is to supply the power required for the traffic signal display device using the signal line of the currently installed and operated traffic light, and to back up the power to the uninterruptible power supply in consideration of the power failure, and the lighting of each signal lamp and It implements a function that automatically detects the light off, calculates and stores the duration of the signal, displays the waiting time when stopping and the duration and direction of traffic and walking, and the signal lamp turns on and off. The present invention provides a software and hardware technology implementation for a traffic signal display device having a function of matching the calculated time, automatic switching of power in case of power failure or traffic signal failure, and displaying previously stored traffic signal information.

1 is a schematic diagram of an overall system of the present invention, a processor unit 10 having software for controlling display apparatus for calculating and processing a duration of an input traffic light, and a processor peripheral unit 20 for storing and executing a software program. The traffic signal matching unit 30 for automatic traffic signal detection processing, the traffic signal display unit 40 for displaying the waiting time and remaining time and progress of the traffic signal, the uninterruptible power supply and the display device in consideration of the occurrence of power failure or failure It consists of a power supply unit 50 for supplying the power required for.

<Processor part (10)>

The processor unit 10 is the core of the traffic signal display system, using a microprocessor equipped with traffic signal processing data for processing various traffic signal information data and input information, and turning on and off the traffic signal according to the traffic flow. Enter and calculate the time in the form of time, and store the protocol, and feedback protocol to match the calculated time with the traffic signal, and according to each traffic signal to display the waiting time and the remaining time and progress direction at the time of passage and walking It controls the display device by controlling the display device and detecting the power failure signal and the failure signal and converting it into a traffic signal suitable for the existing traffic flow.

The processor unit 10 receives signals for stop, alarm, and progress of a traffic signal, power failure, and failure signals from the traffic signal matching unit 30 which performs automatic traffic signal detection processing, and processes and stores a software program for controlling a traffic signal. And it is stored in the processor peripheral portion 20 for execution, and transmits to the traffic signal display unit 40 for displaying the waiting time and the remaining time and the progress of the traffic signal. In addition, in case of a power failure or a failure of a traffic signal, the power supply is automatically switched to the uninterruptible power supply, and the previously stored traffic signal information is transmitted to the traffic signal display unit 40.
