Description

Sidewalk safety island

Technical Field

The utility model relates to a pavement safety island.

Background

The safety island is a safety device arranged on a zebra crossing in the middle of a pedestrian road and comprises an island body, an island head and an island tail, wherein a yellow warning line is arranged on the side surface of the island head, and warning columns with reflective films are arranged at two ends of the safety island, so that a driver can be reminded to warn at night to avoid. The safety island is set up to enable people to form a habit of crossing streets for the second time, namely, the people arrive at the safety island of the pedestrian in the center of the road at the first green light time, and the people walk the rest of the road after the green light is turned on for the second time.

The existing safety island is single in structure, the reflective film on the warning column is poor in warning effect, and when a pedestrian walks to the position of the safety island, the pedestrian cannot be prompted to move forward continuously according to the green light remaining time.

SUMMERY OF THE UTILITY MODEL

Not enough to above-mentioned technique, the utility model provides a can monitor the pedestrian automatically and open red blue flashing light to can continue the pavement safety island that moves ahead according to the green light remaining time to the pedestrian suggestion.

The utility model provides a technical scheme that its technical problem adopted is:

a sidewalk safety island comprises an island body, an island head and an island tail, wherein a plurality of laser transmitters are arranged on the front vertical surface and the back vertical surface of the island tail at equal intervals, and a plurality of receivers corresponding to the laser transmitters are arranged on the back vertical surface of the island head; the laser emitter is characterized in that the island head and the island tail are respectively provided with a stand column, the top of each stand column is provided with a red and blue flash lamp, the red and blue flash lamps and the receivers are connected with a controller, and the controller controls the red and blue flash lamps to light up when at least one receiver cannot receive the signal of the laser emitter.

Further, the traffic light warning device further comprises a sound prompting module, the sound prompting module comprises a loudspeaker and a voice chip, the controller is provided with an interface connected with a traffic light controller of the sidewalk, the controller is connected with the traffic light controller, and when the green light time of the sidewalk is smaller than a set value, the sound prompting module sends pre-stored warning voice.

Furthermore, when the at least one receiver cannot receive the signal of the laser transmitter and the green time of the sidewalk is smaller than a set value, the sound prompt module sends out pre-stored warning voice.

Furthermore, a reflective film is arranged on the surface of the upright post.

Furthermore, the surface of island body is provided with the transparent plate, the below of transparent plate sets up solar panel.

Further, protective covers are arranged on the laser transmitter and the laser receiver.

The utility model has the advantages that:

it can monitor the pedestrian and open red blue flashing light after standing on the safety island automatically through setting up photoelectric sensor, plays stronger warning effect to the driver. The voice prompting device can also send prompting voice whether to continue to move forward or wait to the pedestrian through the voice prompting module according to the remaining time of the green light.

Drawings

FIG. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a schematic circuit diagram of the present invention;

in the figure, an island body 1, an island head 2, an island tail 3, a protective cover 4, a stand column 5, a red and blue flash lamp 6 and a solar panel 7.

Detailed Description

For a better understanding of the present invention, embodiments of the present invention will be explained in detail below with reference to fig. 1 to 2.

The utility model discloses a body of island 1, island head 2 and island tail 3 are provided with the through-hole on the safety island and are used for fixing through bolt and road surface. As shown in fig. 1, a plurality of laser transmitters (5 in fig. 1 are provided according to actual width setting) are provided at equal intervals in front and rear of the front vertical surface of the island tail 3, and a plurality of receivers corresponding to the laser transmitters are provided on the rear vertical surface of the island head 2. When the laser transmitter and the laser receiver are opposite photoelectric sensors, such as a volitan photoelectric sensor with the model number of LXDJ-31, when the laser transmitter and the laser receiver are used, the laser transmitter and the laser receiver are always connected with a power supply, the signal output end of the laser receiver is connected with a controller, and the controller can select a conventional singlechip, such as an 8052 series singlechip. The broken line in fig. 1 indicates the laser emission route. A protective cover 4 is arranged on the laser transmitter and receiver, the protective cover 4 preferably being of a visor construction. Of course, concave grooves can be arranged on the rear vertical surface of the island head 2 and the front vertical surface of the island tail 3, the laser emitter and the laser receiver are positioned in the grooves, and the depth of the grooves is about 10-15cm, so that the sensor can be prevented from being polluted by foreign matters.

The island head 2 and the island tail 3 are respectively provided with a stand column 5, the top of the stand column 5 is provided with a red and blue flash lamp 6, the red lamp is four LEDs 1, the blue lamp is four LEDs 2 in figure 2, and the red lamp and the blue lamp are all driven by triode switches. The red and blue flash lamp has the same structure as the warning lamp. The red and blue flash lamps 6 and the receiver are both connected with the controller, when a person steps on the island body 1, at least one photoelectric sensor is blocked, and the controller receives a signal to control the red and blue flash lamps 6 to light. And a reflective film is also arranged on the surface of the upright post 5.

As a further embodiment of the present invention, it further includes a voice prompt module, as shown in fig. 2, the voice prompt module includes a speaker B and a voice chip ISD2560, the controller is provided with an interface connected with the traffic light controller of the sidewalk, the controller is connected with the traffic light controller, when the green light time of the sidewalk is less than a set value (e.g., 5 seconds) the voice prompt module sends a pre-stored warning voice, e.g., "please wait for the next green light" here, the "passage time is not enough, please wait for the next green light" etc. Of course, another warning manner of the sound prompt module is: when the photoelectric sensor detects a pedestrian (namely at least one receiver cannot receive the signal of the laser transmitter), and the green light time is less than a set value, a voice alarm is sent out.

For make full use of solar energy, the surface of island body 1 is provided with the transparent plate, the below of transparent plate sets up solar panel 7, and this structure is the same with current road surface solar panel setting mode, and the transparent plate forms airtight space with island body 1, and solar panel is located airtight space, transparent plate surface antiskid. Be provided with lithium cell and the module of charging in island head 2, solar cell panel is connected for lithium cell charging with the module of charging. Of course, the utility model discloses a power source can also insert the commercial power, set up the data line that the power cord is connected with the traffic lights controller after the wire casing on the road surface during the installation and put in the wire casing can.
