Description

[0002] Stand-alone power supply and wireless notification sidewalk system that detects a pedestrian to cross < RTI ID = 0.0 >

A pedestrian having an intention to cross a road in a crosswalk or the like of an intersection presses a guidance pavement block for a visually impaired person to transmit the intention to the traffic signal controller to the traffic signal controller, The present invention relates to a sidewalk block system that reaffirms that a traffic signal controller is detecting a traversal intention through guidance.

In particular, a sidewalk block equipped with a wireless transmitter is installed without changing the traffic signal facilities installed on the existing roads, so that the pedestrians can see the information for crossing the road, A pedestrian crossing signal is required to be provided to the traffic signal controller by simply pressing the block, thereby positively and actively allocating the pedestrian signal.

In addition, a sidewalk block having a wireless transmission function may be connected to an external power source by mounting a piezoelectric element or a solar power generation panel, or by using electricity produced through a solar power generation panel without the assistance of a battery or a pedestrian By using the electricity generated by the piezoelectric element to make the radio signal and to transmit the signal to the traffic signal controller, it is possible to drastically reduce the production unit cost and the operation cost, It includes functions that can be delivered simultaneously.

This method can be used as a means of recognizing pedestrians when constructing future traffic signal system as well as providing accurate information for quickly assigning pedestrian signals to current traffic signal controller.

At the intersection, the pedestrian crossing signal is generally operated in a fixed time system in which a fixed time is allocated regardless of the presence or absence of a pedestrian.

Accordingly, a pedestrian waiting in a pedestrian crossing associated with an intersection must wait for a time for the signal to change according to the existing signal system regardless of the traffic volume of the road and the presence of the pedestrian, and the vehicle turning right on the intersection is also a pedestrian There is a situation in which it is necessary to wait even if there is not. In other words, the pedestrian and the vehicle often wait for the crosswalk signal to change in a lump without consideration of the pedestrian.

In order to compensate for this, there has been a recent change in the traffic signal system, such as the introduction of a signal by pressing a button on a pedestrian crossing rather than an intersection.

It is difficult to perform post-management and additional repair due to disconnection, and it is difficult to control the traffic signal controller equipment or controller structure in order to manage multiple crosswalk signals. There is a difficulty in connecting the power to the crossing button. Particularly, it is inconvenient that pedestrians, especially visually impaired people, must move to pedestrian traffic lights and press buttons.

Although there are no pedestrians at the other intersection, the adverse effect of social resource waste is clear due to the increase in waiting time of the vehicle which can not be made straight or turn right due to the pedestrian signal, and it can be a main factor causing air pollution. It is considered that there will be an adverse effect on the environment by increasing the emission. In addition, in a pedestrian crossing where the pedestrian signal assignment time interval is long, some pedestrians may cross the pedestrian from the stop signal, thus posing a risk of human accidents.

It is possible to install a solar power panel or a radio transmitting device with a piezoelectric element on a pedestrian crossing associated with an intersection so that it can be operated without an external power source such as a sidewalk block for a visually impaired person placed in a waiting area of a pedestrian, To improve the signal control mechanism to assist pedestrians in crossing pedestrians and pedestrians, and to reduce the waiting time of vehicles passing over pedestrians and crosswalks.

The present invention described above is an external power supply independent pedestrian wireless notification sensing pavement block and control method utilizing a piezoelectric element or a solar power generation panel.

There are a number of sidewalk blocks that pedestrians waiting to cross the crosswalk for the implementation of the invention step on to express their intention to cross the intersection. The corresponding sidewalk block incorporates a pedestrian sensing device including a photovoltaic element or a pedestrian sensing transmitter including a piezoelectric element and a radio transmitter to indicate that there is a pedestrian in a self generating mode without an external power source.

In a system such as a sidewalk block in which the radio transmission device is embedded, transmission devices arranged at a plurality of positions can be connected to one control device and used for distinguishing from other control devices close to each other. Make and install. This makes it possible to use at intersections of complex structures.

When a pedestrian signal is received on the pedestrian crossing, the pedestrian signal light is turned on and off at regular intervals until the gait signal is assigned, by connecting the receiver to the traffic signal controller to receive the signal from the transmitting device And if there is a voice guide for the visually impaired, the voice and the transit signal are guided to the pedestrian, and the transverse intent is transmitted to the traffic signal controller and the transit signal is informed of the assignment.

If the pedestrian crosses the road, the system is initialized and operated again.

A pedestrian who intends to cross a road at a crosswalk or the like of an intersection passes an intention to cross a road by treading on a visual information content block or the like and transmits the intention to the traffic signal controller to the traffic signal controller, It has the effect of notifying the pedestrian that the intersection signal controller is detecting the doctor through the blinking of the stop signal and the voice guidance.

Particularly, it is possible to inform the traffic signal controller that a pedestrian crossing signal is required by acting on a sidewalk block for the visually impaired, in which the wireless transmitter is internalized not only to the general public but also the visually impaired, thereby enabling the pedestrian signal assignment to be actively performed.

Using the electricity produced by the solar power panel or using the electricity produced by the piezoelectric element with the weight of the pedestrian stepping on the sidewalk block, the sidewalk block with the wireless transmission function generates the radio signal, It can be operated without a battery, so that the production unit cost and operating cost can be drastically reduced. In addition, there is also an effect that one receiving controller can simultaneously process 10 or more multiple transmission signals simultaneously.

Therefore, through active signal control considering pedestrian crossing and traffic volume, it provides fast and safe crossing of pedestrians as well as traffic smoothly by eliminating the waiting of vehicles without pedestrians. Especially, it is possible to protect the pedestrian when the weather deteriorates at nighttime or rainy weather, and it is possible to assign the pedestrian crossing signal in a short period of time, thus reducing the incidence of human accidents. In addition, in the absence of a pedestrian, it is possible to assign a signal without assigning a crossing signal, thereby increasing the vehicle communication rate

Thereafter, this information is transmitted to the transmission control unit (S402), and the transmission module transmits an RF signal including the identification (ID) of the corresponding sidewalk block (S404).

When receiving the RF signal (S408) in a signal controller device with a radio receiver, the plurality of sidewalk block transmit RF signals representing the traversing information are analyzed and classified through decoder 122 (S410). The signal control unit 124 allocates and controls the pedestrian crossing signal for each road classified (S412).
