Problems solved by technology

However, the existing voice safety reminder adopts a wide-angle loop playback mode with a large coverage area. This method is likely to cause auditory fatigue for pedestrians and does not achieve the purpose of effective reminders.

Embodiment Construction

[0018] Such as figure 1 Shown: a directed broadcast method, comprising the following steps:

[0019] Step 1: Set the detection line;

[0020] Step 2: Capture camera tracking and monitoring;

[0021] When no red light signal is detected, a non-detection signal is sent to the intersection host;

[0022] When a red light signal is detected, a detection signal is sent; when a signal touching the detection line 4 is detected, a signal to play a safety warning voice is sent to the intersection host;

[0023] If no touch signal is detected, no voice signal will be played;

[0024] Step 3: After the intersection host receives the signal to play the voice, it controls the ultrasonic transmitter panel to send out the voice signal.

[0025] The present invention also includes a multiplier and a power amplifier board 1, the multiplier modulates the recorded safety warning language and ultrasonic waves, and the modulated signal 3 is input to the power amplifier board, and the power amp...

Abstract

The invention relates to a directional broadcasting method. The method comprises the following steps of step 1, setting a detection line; step 2, carrying out tracking and monitoring by means of a snapshot camera; upon detecting a red light-free signal, sending out a non-detection signal to an intersection host; upon detecting a red light signal, sending out a detection signal; upon detecting a signal touching the detection line, sending out a signal for playing the safety warning voice to the intersection host; upon detecting no touch signal, not playing any voice signal; step 3, upon receiving a voice signal for playing the voice by the intersection host, controlling an ultrasonic transmitter panel to send out the voice signal. According to the invention, only pedestrians who step over asafety area are reminded and urged to retract back into the safety area. Therefore, other non-violation pedestrians are not influenced at all. The method is extremely high in directivity.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a directional broadcast method. Background technique [0002] At present, a variety of technical means have been adopted for motor vehicle violations, which largely control the dangerous driving behavior of motor vehicle drivers. However, although punishment measures have been issued for pedestrian violations, the effect is not good. Obviously, voice safety prompts have been installed at many traffic intersections. However, the existing voice safety reminder adopts a wide-angle loop playback mode with a large coverage area. This method is likely to cause auditory fatigue for pedestrians and does not achieve the purpose of effective reminder. Contents of the invention [0003] The present invention aims to overcome the defects of the prior art and provide a directional broadcast method, which only reminds pedestrians who have crossed the safe area and urges them to wit...
