The invention provides a new type of dynamic pedestrian crossing signal lamp, which can solve the problem that previous pedestrian crossing signals are easily misjudged by color-blind patients due to the integration of two color signal lamps in the same unit, thereby affecting road traffic safety. It includes a master control microcontroller, a power supply circuit, a signal sampling circuit, a power switch circuit and a signal light display unit, the signal sampling circuit, a power switch circuit are connected to the master control microcontroller, and the power supply circuit includes a digital circuit power supply circuit and a signal light display power supply circuit, and a signal light display The power supply circuit is connected to the signal light display unit through the power switch circuit, and the signal input terminal of the signal light display unit is connected to the master control microcontroller. The signal light display unit includes an upper display unit and a lower display unit, both of which are displayed by LED tubes. It is: in the signal light display unit, the red human figure display part, the red countdown digital display part and the green countdown digital display part and the green countdown digital display part are alternately displayed through the upper display unit and the lower display unit.
Description
technical field [0001] The invention relates to a road traffic signal light, in particular to a signal light which can vividly reflect the walking posture in an animation form, and the red man pattern and the green man pattern appear in different units, specifically a new dynamic pedestrian crossing signal light. Background technique [0002] At present, the known pedestrian crossing signal lights are composed of upper and lower units, wherein the upper unit is a combination of red pedestrian standing patterns and green pedestrian static walking patterns, and the lower unit is a red and green two-color countdown digital display combination. The disadvantage is that the red pedestrian standing pattern, the green pedestrian static walking pattern, and the red and green countdown digital displays are all displayed in the same unit, which may easily cause misjudgment by color-blind patients in practical applications and affect road traffic safety.
