Abstract
Description
The present invention relates to a traffic signal safety system for a pedestrian crossing, and more particularly, to a traffic signal safety system for a pedestrian crossing that detects a pedestrian approaching a safe line in a crosswalk,
A second function for changing the stop signal of the pedestrian crossing to a pedestrian signal when the pedestrian who wants to cross the pedestrian with priority over the vehicle progress signal in the time zone in which there is no pedestrian,
And a third function of detecting a pedestrian crossing the crosswalk when a visually impaired person is detected and outputting a voice of a visually impaired person, into an integrated system for efficient pedestrian safety management on a pedestrian crossing will be.
The present invention relates to a traffic signal safety system for a pedestrian crossing. Generally, a pedestrian crossing for pedestrians is installed on a road on which a vehicle is running, and a pedestrian crossing signal is generated on a pedestrian crossing Pedestrian traffic lights and pedestrian crossing entrance In India, there is a safety line that pedestrians can safely wait.
However, the conventional pedestrian crossing has merely a signal function to allow the pedestrian to recognize only the situation of whether the pedestrian crossing signal is stopped (red) or walking (green), so that the pedestrian signal light is waiting for crossing the pedestrian crossing in the stop signal state Many pedestrians have to wait safely outside the safe line area, and many pedestrians are unconsciously entering the safety line area or entering the roadway beyond the safety line area and are waiting for the safety accident.
In order to solve the above problems, the contents and drawings of the prior art 1 Korean Patent Application No. 10-2006-0037770 and the prior art 2 Korean Patent Application No. 10-2013-0168933 will be described. In addition, A pedestrian sensing unit is installed at the entrance of a pedestrian crossing, and when the pedestrian senses that the pedestrian has entered the safety line in the stop signal state of the pedestrian signal lamp, a device is provided to notify the driver that the pedestrian should go back.
However, if the pedestrian is present in the safety line, it can be detected. However, when the pedestrian crosses the safety line, if the pedestrian enters the road edge, it can not detect the pedestrian beyond the range of the detection sensor. .
When the pedestrian sensing unit detects the pedestrian, the pedestrian sensing unit only detects whether the pedestrian has entered the safety line, and performs only a simple function of outputting the voice of the danger guidance. There is a problem in that a simple function is inefficiently operated because a complex function of various traffic functions can not be performed after installing a system with a large budget.
In order to efficiently operate the pedestrian signal of the pedestrian crossing, when the pedestrian crosses the signal system, the signal system is operated mainly for the time when there are not many pedestrians. When the bell button installed on the signal lamp is pressed, There is a problem that pedestrians can not recognize pedestrians who use pedestrian crossing and pedestrians to change from green to green signals.
In order to solve this problem, a prior art document 3 of Korean Patent Publication No. 10-0742558 will be described. A pedestrian sensor module using an infrared sensor in which a pedestrian signal lamp operates only when there is a pedestrian to walk on a pedestrian crossing, and a control method thereof, are disclosed.
However, the above-mentioned prior art document 3 has a problem that traffic and pedestrians such as rural areas are only located at a quiet place.
In urban areas with many traffic and pedestrians, it is necessary to follow the normal traffic signal cycle in the daytime, and when the pedestrian is detected, the pedestrian signal light should be changed from the stop signal to the walking signal when the pedestrian is detected. There is a problem in that there is no method for checking the contents.
In addition, since only the simple function of controlling the traffic lights after the detection of the pedestrian is performed, a complex function of various traffic functions can not be performed after installation of the system with a large budget, and simple functions are inefficient.
In addition, in some crosswalks, a button for the visually impaired is installed in the signal lamp holder, so that a bell button is pressed to output a guidance voice for the visually impaired so that the visually impaired can use the pedestrian crosswalk.
However, there is an inconvenience that the visually impaired should find the bell button. In order to solve this problem, a system has been operated in which a visually impaired person presses a remote control on a pedestrian crossing via a remote control to output a guidance voice for a visually impaired person through wireless communication.
However, when the wireless remote controller is pressed on the pedestrian crossing due to the nature of wireless communication, there is a serious problem of causing confusion by the visually impaired because the voice or output of the voice is outputted from several places simultaneously by the voice output part of the intersection.
Also, there is a problem that the visually impaired person can use the remote control only when the remote control is carried and can not be used if the remote control is not carried.
In order to solve the above problem, in Japanese Unexamined Patent Application Publication No. 2013-161145, '
However, referring to FIG. 1, the sensing area of X1, the sensing area of X2, and the sensing area of X3 are overlapped with each other, so that they can be used only for guidance voice of a simple blind person.
(Second function) to output the guidance voice so that the pedestrian entering the safety line for the purpose of the present invention is retracted backward (first function) When the pedestrian attempting to cross the pedestrian crossing detects a pedestrian signal, the stop signal is changed to a pedestrian signal (the third function). When the visually impaired person senses to cross the pedestrian crossing, the pedestrian signal is output (fourth function) (5th function) to output a warning message for violation,
When operating the integrated system as described above, the safety line detection zone, the danger detection zone, the crossing zone detection zone, and the crosswalk detection zone are not overlapped with each other, It is necessary to judge that they have been correctly detected according to the detection area of the sensor.
Prior art document 4 Referring to FIG. 1, when a person is on the roadway of a pedestrian crossing and the boundary line of the crosswalk, the X1 sensing area, the X2 sensing area and the X3 sensing area are detected at the same time. The announcement voice to go out from dangerous area, the guidance voice for the visually impaired, and the warning message for the warning of warning of warning) will be outputted in a superimposed manner.
The prior art document 4 discloses a technical feature (refer to paragraph 31) in which the pedestrian guidance device outputs a guidance voice for the visually impaired and controls the guidance voice to not be stopped until the visually impaired person completes the walking. It is designed to be operated only for the visually impaired guidance voice output.
(Second function) to output the guidance voice so that the pedestrian entering the safety line for the purpose of the present invention is retracted backward (first function) A pedestrian attempting to cross the pedestrian crossing is changed to a pedestrian signal (third function), and a guidance voice is output when the visually impaired person is crossing the pedestrian crossing (fourth function) An integrated system for outputting a warning voice (fifth function) must be operated,
When performing such a complex operation, it is necessary to solve the problem that the other guidance voice is not outputted at the time of outputting the guidance voice of the visually impaired person.
In particular, for convenience of the visually impaired, it should be operated in parallel with the conventional voice announcement device for the blind who is operating the button. Therefore, during the time when the voice guidance of the visually impaired is being outputted, There is a problem that no countermeasure is taken.
The prior art document 4 discloses a technical feature (see paragraph 31) in which the
However, this is a simple repetition of the guidance voice until the visually handicapped completes the crossing, and there is a problem that it is impossible to prevent overlapping with other guidance voice output which is a serious problem.
In addition, in a system in which various functions for the purpose of the present invention are integrated, it is possible to select and output only the necessary guidance voice among the guidance voices detected at a close time when the proximity time is detected simultaneously in each sensing zone, It is necessary to set the order of the guidance voice output and to output the guidance voice output.
In the prior art document 4, the pedestrian detection sensor includes a camera for sensing a region X1 around the entrance, and an infrared (or ultrasonic) sensor for sensing a region X2 surrounding the area around the entrance. Technical features (see paragraphs 14-15 and 19) for judging whether or not a person with visual impairment is detected by detecting a cane for the visually impaired.
However, it is necessary to judge whether the blind is a blind person by detecting the blindfold of blind people. This is because there is no measure to distinguish the blindfold possessed by the climbers and the cane carried by the elderly. There is a problem that chaos is caused.
According to the prior art 5 disclosed in Japanese Patent Application Laid-Open No. 2003-217086, the presence of pedestrians, persons with disabilities and obstacles is measured from the size, shape and position of the pedestrian P (See
The pedestrian detection device measures the speed (speed and direction) of the pedestrian through the change of pedestrian position measurement (see paragraph 32) and the
'Pedestrian detection system' displays the pedestrian size, shape, and position by points indicated by three-dimensional X, Y, and Z coordinates to determine walking speed, human presence, and obstacles and obstacles (see paragraphs 32-34)
&Quot; A signal control function according to the detection of a pedestrian by a pedestrian signal control system and a voice output function of a traverse direction ".
However, there is a problem that the prior art 3 and the prior art 4 have the same problems.
Even if a new system and an integrated system are invented by combining the technical features of the prior art 3, the prior art 4 and the prior art 5,
As pointed out above, there is a problem that the prior art 3, the prior art document 4 and the prior art document 5 have the same problem.
In addition, there is a problem that the sensing unit does not have a device for storing the captured image data for recycling, so that it can not be used as image data such as a clerk, and the captured image can not be linked with the central server.
In addition, there is a problem that redundant facilities and budget are wasted because a system that performs only one function of the voice output function of the pedestrian risk alert, the pedestrian detection signal conversion function at a specific time, and the voice output function of the visually impaired person is operated.
In the case of the integrated system that integrates the voice output function of safety alert entry into the safe line, the pedestrian detection signal conversion function at a specific time, and the voice output function of the visually impaired person, the shape of various crosswalks (curved crosswalk) , It is necessary to set the safety line detection zone, the danger detection zone, the transit atmosphere detection zone, and the blind zone so as to be suitable for the respective situation.
In the case of integrated system that integrates voice output function of safety alert entry announcement announcement, pedestrian detection signal conversion function at certain time of day, and voice output function of visually impaired person, all functions of each function are operated on site or required So that the function selection device is not provided.
A traffic signal safety system for a pedestrian crossing according to an embodiment of the present invention solves the problems of the conventional systems and methods and provides a new concept system different from the conventional systems and methods .
In order to solve this problem, the pedestrian detection unit and the detection zone entering identification unit in the pedestrian signal light in the state of the pedestrian signal light entering the safety line zone, entering the danger detection zone , It is precisely detected and judged whether the pedestrian has entered the crossing atmosphere detection zone. If it is judged that the pedestrian has entered the safety line detection zone, the control unit informs the user through the voice output unit '
If it is determined that the pedestrian has entered the danger detection zone, the control unit informs the user through the voice output unit '
If it is determined that the pedestrian has entered the transit atmosphere sensing zone in the state of the walking stop signal in the selected time zone, the pedestrian traffic light should be changed from the red signal to the green signal so that an efficient traffic system can be operated.
In addition, when the pedestrian is a visually handicapped person, it is possible to easily and accurately judge the pedestrian without confusion with the climber's staff and to output a guidance voice corresponding to the guidance voice. You should not print.
