Infrared sensing Pedestrian road traffic warning signal light
First, what is the working principle of the pedestrian voice prompt column traffic
warning signal light?
1) pedestrian voice prompt column traffic warning signal light is an auxiliary equipment for pedestrian
crossing pedestrianized design facilities. and The main column and the sub-column are required to be
installed on both sides of the pedestrian zebra crossing to visually and audibly remind the pedestrians
crossing the street not to smash red lights and pass the pedestrian traffic lights safely through the road.
Through voice prompts, people are urged to follow the traffic laws and regulations, and develop good
civilized travel habits to ensure road traffic safety.
2) When the green light of the pedestrian light is on, when the pedestrian passes between the main
column and the sub-column, the infrared grating is blocked, but the device does not emit a voice prompt;
when the red light of the pedestrian light is on, and the pedestrian from the main column When passing
between the sub-column and the sub-column, the infrared grating is blocked. At this time, the main column
and the sub-column will simultaneously emit a voice prompt to indicate that the pedestrian has red light.
Second, pedestrians through the street pedestrian voice prompt column traffic warning signal light
to achieve the functions?
1) Intrusion alarm function: Connect the main pole to the input line of the 220V traffic signal light, and connect
it according to the red and green lines; adjust the grating position of the main sub-column so that it can receive
infrared rays and synchronize with the pedestrian signal light. When the green light of the pedestrian light is on,
when the pedestrian passes between the main column and the sub-column,for the grating infrared radiation is
blocked, but the device does not emit a voice prompt; when the red light of the pedestrian light is on,then the
pedestrian from the main column and When the sub-columns pass, the grating infrared is blocked. At this time,
the main column and the sub-column will simultaneously emit a voice prompt to prompt the pedestrian to have a
red light, and the voice prompt content can be customized.
2) Considering that someone has a red light in the middle of the night, the alarm sound will disturb the people.You
can set the voice prompt to switch the machine time through the mobile APP. for The factory default is 8:00 am to
automatically turn on the alarm prompt, and the night alarm will stop at 20:00. Other functions work normally. .
Third, the pedestrian voice prompt column traffic warning signal light technical parameters:
1) The outer casing is made of aluminum alloy/sheet metal, which has good oxidation resistance and does not fade
during use. 2) The total height is 1.2-1.3m. The top is composed of red “●” and green “↑”. The front height is 1.1-1.2m.
2) The front display is the sounding part, and the special design ensures that the sound will propagate in the specified
3) The inner side of the prompting column is a grating component, and the grating used is industrial-specific custom,
and the low temperature resistant working characteristic is far superior to the ordinary grating. and The reaction time
is ≤200ms, the transmission distance is farther, the standard can be 10m, and the anti-environment interference ability
4) The back of the pedestrian voice prompt column traffic warning signal light is the detection board. When the prompt
column is faulty, the inspection board can be removed for maintenance.
5) There is a 6 Pin terminal inside the prompt column for external wiring. The main and auxiliary columns are connected
by a 3*1.5m2 cable, which keeps the display and voice between the main and sub-columns synchronized.
6) Shell protection grade: IP53; high and low temperature resistance: -20 °C ~ +55 °C.
Fourth, pedestrian crossing voice prompt column product features
1) It is not necessary to connect 220V main power supply, only need to receive the red light from the pedestrian signal light,
and the pedestrian green light line is connected to the corresponding terminal block of the prompt pile.
2) Debugging uses the mobile APP to operate wireless, and all settings can be completed without opening and the rear
b. Switching machine time
c. Changes to voice content
3) Convenient maintenance: When the pedestrian signal light is connected to the prompting pile, it is convenient to know the
immediate status of the signal after three-way switch with indicator light.
4) Concealed bottom seat design: After the product is installed, the studs on the base flange are not visible, and the appearance
5) There are signal lights before and after: pedestrians who have not entered the zebra crossing and are already in the zebra
crossing can know the status of the current pedestrian signal light for the first time.
6) SMD LED display: Compared with the traditional plug-in display, the pedestrian can see the content on the display well on the
7) Display content update: You can use the mobile APP to change the content on the display in real time, without changing the PC.
8) Patented product: The appearance of the product has obtained the design patent, and the control board and mobile APP have
obtained the software copyright.
In addition to the pedestrian voice prompt column traffic warning signal light, We also produces
other traffic lights:
1, 200mm red cross green arrow traffic lights
2, 125mm red and green traffic lights
3, 125mm teaching red yellow green traffic lights
4, 100mm red yellow green traffic lights, etc.
