Intelligent traffic control system for blind and its method

Abstract

The invention discloses an intelligent traffic control system for the blind and a method thereof. The system comprises a transmitting device and a receiving device, wherein the connection relationship of internal modules in the transmitting device is that a data reading unit is sequentially connected with a modulation encoding unit and a transmitting unit, while the connection relationship of internal modules in the receiving device is that a receiving unit is sequentially connected with a decode unit, a control unit and an audio unit, and the control unit is connected with the receiving unit. The method is to arrange transmitting point of the transmitting device at each traffic road junction, the transmitting point of the transmitting device forms the traffic light signals received at each traffic road junction into a ring, each transmitting point of the transmitting device transmits the traffic light signals to the located road junction, the receiving device directionally receives the traffic light signals from the transmitting point of the transmitting device and obtains the traffic signal light information of the forward direction which is indicated by speech. The intelligent traffic control system for the blind can overcome the existing potential dangers for the blind going on a journey and ensure that the blind and the color blind can hear the traffic condition ahead when crossing a traffic light.

Description

technical field [0001] The invention relates to the field of traffic facilities, in particular to a blind intelligent traffic control system and a method thereof. Background technique [0002] Existing crossroad traffic signal light system generally utilizes three kinds of signal lamps of red, green and yellow to indicate whether the various directions of the intersection can pass through, or add arrow signal lights to indicate which (some) directions can be driven. Some intersections are for convenience. For traffic, the remaining time countdown display board for red light waiting and green light passage is also installed on the indicator light frame. When a pedestrian passes through the crossing, he must use the visual method to see clearly the status of the traffic lights ahead. However, blind people, as a disadvantaged group in the visual field, do not know the signal lights ahead at all; for most color blind people, red and green are the easiest to confuse, even if the...
