Description

School zone safety system

The present invention relates to a school zone safety system, and more specifically, to increase children's safety and traffic leader's convenience in the school zone, an integrated system such as an electronic signboard, broadcasting, and safety induction has been constructed (構築) to increase recently with the effect of vision and hearing. It is about the school zone safety system that helps to prevent traffic accidents.

In general, as a measure for pedestrian safety for children or minors, a school zone, a child protection zone, is specially established for roads near elementary and secondary schools, especially for roads in front of the school.

School zones are installed so that roads in front of the school and transportation facilities around the school can be made through color pavement, traffic signal improvement, protection fences, new traffic signs, and speed limit.

In general, children tend to cross roads without paying attention because they have relatively low concentration and judgment compared to adults, and as a result, in areas where there are many conflicts between children and vehicles, such as the school zone, the incidence of traffic accidents is higher than other regions. Side.

Accordingly, in order to prevent traffic accidents within the school zone, physical accident prevention measures such as safety fences, speed bumps, guide signs, warning signs, and intermittent cameras are installed, or a method of legalizing the speed limit of vehicles (30 km) is still in use. The incidence of traffic accidents in the school zone is still high compared to other countries.

In general, when analyzing traffic accidents occurring in the school zone, accidents occur intensively at a specific time point or at a specific time when there are many children's movements. In most cases, it is a place or crosswalk where the field of view is not opened due to obstacles such as banners.

The school zone operated as described above may contribute to the walking safety of a child to some extent, but it is not possible to inform the walking child of the driving vehicle's warning or speed, so that more safety accidents occur in the school zone. There was.

In addition, since there is no separate sign to inform the driver of the vehicle speed in the current school zone, there is another problem in that more safety accidents occur due to overspeed.

Accordingly, in order to safely pass children in the school zone, the development of a device or a system that accurately recognizes a vehicle driver and a pedestrian in an accident-prone area has been greatly emphasized.

For reference, IoT, which appears in the names of components such as the wireless IoT controller 50 and the IoT controller (C) on the specification, is an abbreviation of the Internet of Things, which is the Internet of Things. It refers to an environment in which real-time data generated from sensors, etc. are exchanged through the Internet without human intervention. In other words, it refers to a physical network capable of automatically transmitting and receiving real-time data without human intervention.

Hereinafter, a preferred embodiment of the school zone safety system 100 according to the present invention will be described with reference to the drawings.

Referring to FIGS. 1 (not shown in the drawing) and FIG. 2, the school zone safety system 100 of the present invention includes a seatbelt 10 for outputting a stationary broadcast announcement of a vehicle and a vehicle or vehicle that enters the school zone. It is connected to the wireless transmitter (30) and the wireless receiver (30) for receiving signals input from the wireless transmitter (20) and the safety bell (10) and the wireless transmitter (20) for outputting a passing broadcast message in advance. When the electric sign board 40 and the safety bell 10 or the wireless transmitter 20 displaying the designated phrase are operated, a plurality of floor safety lights 70 and lamps embedded in the floor safety lights are operated in synchronization with this. When operating the wireless IoT controller 50 and the safety bell 10 or the wireless transmitter 20 that controls the speaker 60 and the wireless receiver 30 and the wireless IoT controller 50 that outputs a corresponding broadcast message ) Consists of an IoT controller (C) that controls the operation.

The seatbelt 10 is that when a student attending school on foot presses the seatbelt artificially, after about 5 seconds, a broadcast to stop the vehicle is transmitted through the speaker 60. The seatbelt 10 will be preferably installed at a height where children can easily enjoy it, such as a post (not shown) at the crosswalk entrance.

The content of the comment is to broadcast the "stop the passing vehicle and pass the students." Through the speaker 60. In the above case, there is no person in charge of controlling the pedestrian crossing of the school zone or the like, so that in the event of an emergency, the student can directly press a button.

For reference, the above broadcast comment "Stop the passing vehicle and pass the students" is only an example, so let's make it known beforehand that it is possible to set any other comment.

As shown in Fig. 1, the radio transmitter 20 is a group of parents who belong to a group called the Green Mothers Association, which are students who perform traffic safety volunteering activities for children and school roads and pedestrian traffic safety activities at pedestrian crossings near the gates of elementary schools. It is to be carried in the school zone during the school day.

That is, as described above, an undergraduate type serving at a pedestrian crossing entrance of a school zone near the school has the wireless transmitter 20 and refers to signals such as a green light or a red light of a signal (not shown), so that the wireless transmitter 20 It is operated by means of a button or the like to operate a guide broadcasting suitable for a situation through a speaker 60 so that a student or a vehicle operator can listen.

For example, when a button (not shown) formed on the surface of the wireless transmitter 20 is pressed, "△" is broadcast to stop the vehicle. As a broadcast comment of the same content as in the case of the seat belt 10 described above, Stop passing vehicles and pass students. " The speaker 60 broadcasts.

The transmission of the announcement is about 20 seconds. When the announcement is over, the person who has the radio transmitter 20 (a member of the green mother society) presses "▽" again to automatically switch.

The automatic switching means that the vehicle stops as in the above example and corresponds to an action opposite to that of students passing by, and means that students are standing on a pedestrian crossing and the vehicle is switched to a mode through which the vehicle passes. . However, it should be noted that the indications of "△" and "▽" expressed in this specification are exemplary.

In addition, as another example, when there is a need to wait for students who do not stop the vehicle, it is also operated by pressing a button on the surface of the wireless transmitter 20. For example, "▽" formed at the bottom of the wireless transmitter 20 If you press the same button, the announcement through the speaker 60 is broadcast and transmitted, and the message "Wait for students to pass the vehicle." Again, the transmission of the announcement is about 20 seconds.

When the announcement is completed in the same manner as described above, the holder of the wireless transmitter 20 (the member of the green mother society) presses "△" again to automatically switch. As described above, the automatic conversion diagram is for students who correspond to the next procedure after the vehicle has passed to switch to a pedestrian crossing or a crossing mode.

Broadcasting through the radio transmitter 20 as described above ("Students should stop waiting and the vehicle pass through", etc.) is also an example, so it will be revealed in advance that it is not limited thereto.

The person who has the radio transmitter 20 (a member of the Green Mothers Association) is able to directly broadcast information using the radio transmitter 20 according to the situation.

And, referring to FIG. 3, a block diagram showing the wireless receiver 30 is shown.

As shown in the figure, the wireless receiver 30 includes a wireless receiver 31, an I / O (input / output) unit 32, and a memory 33. The wireless receiver 31 directly receives the signals of the safety bell 10 or the wireless transmitter 20, and the I / O unit 32 inputs and outputs the signals of the safety bell 10 and the wireless transmitter 20. It is to play a role. In addition, the memory 33 stores a broadcast message and a displayed text or image of the electronic display board 40.

 As illustrated, the wireless receiver 30 receives a signal such as a safety bell 10 or a wireless transmitter 20, and transmits it to the IoT controller C, so that the IoT controller C can control it. Furthermore, the IoT controller (C) is also possible to control the time to proceed with the broadcast.

In addition, the IoT controller C communicates with the electronic display board 40 to be described below to control the operation of the text to be displayed on the electronic display board 40. To explain this, in the case of flashing the text displayed on the surface of the electronic display board 40 at regular time intervals, it also serves to control the number of flashes.

The electronic display board 40 is interconnected with the wireless receiver 30 to be displayed on a surface (not shown), which is interconnected and set in advance.

The phrases to be displayed on the electronic display board 40 are predetermined in advance, and it is desirable to have general information or publicity (for example, a period of passage, prohibition of drinking and driving, etc.).

The electronic display board 40 in the school zone safety system 100 of the present invention is connected to and formed with a fine dust measuring instrument 80 and displays concentration measurement values of the fine dust measured by the fine dust measuring instrument 80.

Therefore, the concentration of fine dust can be known not only to students who go to and from school, but also to passengers of vehicles driving past the school zone, so that it serves as a reference for whether or not to wear a mask on the corresponding day.

The fine dust measuring instrument 80 is not limited to only the fine concentration value, and it may be desirable to display the weather or weather report of the corresponding date on the electronic display board 40 at any time.

Since the fine dust measuring instrument 80 detects the concentration value and transmits the value to the electronic display board 80 to display the value, a detailed description thereof will be omitted.

In addition, when the safety bell 10 or the wireless transmitter 20 is operated, a plurality of floor safety lights 70 which are simultaneously operated in conjunction with this are formed in school zones, such as near a pedestrian crossing.

When the floor safety light 70 receives a signal from the safety bell 10 or the wireless transmitter 20, LED lamps (not shown) are used to distinguish between the walking direction of the pedestrian and the driving direction of the vehicle. It is displayed separately.

The LED lamp is a member for providing LED lighting. Referring to FIG. 1, a wireless IoT controller 50 is formed to emit light when a control signal of the wireless IoT controller 50 is applied. In addition, the LED lamp is supplied with power by a power source (not shown) built in the module form.

The floor safety lamp 70 is normally turned on by the operation of the safety bell 10 and the wireless transmitter 20, while the LED lamp remains off inside. Detailed description of the technology that is turned on by the above operation will be omitted because it is a well-known technology.

For example, through the operation of the wireless transmitter 20 or the safety bell 10, the vehicle is stopped in front of a pedestrian crossing, and when a student needs to cross the pedestrian crossing, only the floor safety light 70 in the direction of the crossing is turned on. (on) is displayed as a green or blue LED, and on the contrary, when the radio transmitter 20 is in operation, students are waiting and the vehicle needs to pass, only the floor safety light 70 installed in the direction of the vehicle An example would be to display the red LED so that it can be easily identified.

Referring to the operation relationship as described above in the block diagram of FIG. 4, the wireless receiver 30 receiving the signals from the safety bell 10 and the wireless transmitter 20 transmits the signals through the IoT controller C.

Then, the IoT controller C distinguishes whether this is a signal of whether the vehicle is stopped, students should pass, or students stop and stop, and distinguishes whether or not the vehicle is a signal of going through a crossing or a pedestrian crossing, and then wirelessly determines it. The IoT controller 50 is controlled.

That is, the wireless IoT controller 50 is to apply a signal for the operation of the LED lamp built in a plurality of floor safety lights (70).

Accordingly, the wireless IoT controller 50 receiving the control of such a signal from the IoT controller C has a floor safety light 70 installed in the crossing direction of a plurality of floor safety lights 70 and a floor installed in the direction of the vehicle. It is to control the safety lamp 70 so that it can be operated separately. In this way, the IoT controller (C) is to control the operation of the wireless receiver 30 and the wireless IoT controller 50.

The speaker 60 outputs an appropriate broadcast message when the person operates the safety bell 10 or the wireless transmitter 20, that is, an appropriate broadcast message about a vehicle passing or students passing.

It may be desirable to record the above-mentioned broadcasting comment in advance, so that the memory 33 can be properly stored according to the situation so that it can be updated at any time.

Then, the speaker 60 operates the speaker 60 as a control signal of the IoT controller C is applied.

 The wireless IoT controller 50 outputs a signal according to the input signal of the safety bell 10 or the wireless transmitter 20 to output a corresponding broadcast message through the speaker 60 for a certain period of time, and after a certain period of time elapses, Stop printing.

In addition, as described above, after a certain initial time (about 5 seconds) has elapsed after the seatbelt 10 is pressed, a broadcast message indicating the vehicle's stop is output. The wireless IoT controller 50 Also serves to set and control these initial times.

Hereinafter, the operation and operation of the school zone safety system 100 according to the present invention having the above-described components will be described with reference to FIG. 5.

First, when the green children's association undergraduate type with the wireless transmitter 20 is changed to a yellow signal or a red signal by a signal controller (not shown), an appropriate button is operated.

Then, the wireless receiver 30 receiving the signal through the wireless transmitter 20 transmits it to the IoT controller C.

The IoT controller (C) judges the signal received from the wireless receiver 30, distinguishes and discriminates whether the vehicle should pass or vice versa, and determines the appropriate signal for the wireless IoT controller 50. To send.

The wireless IoT controller 50 receives a signal and, if the vehicle is to be stopped and receives a signal of a situation that a student should cross, operate the LED lamp of a preset color (for example, blue or green). do.

On the contrary, if the wireless IoT controller 50 receives a signal of a situation in which the vehicle must travel and the student stops and stops walking, this is also an LED lamp of a preset color (for example, red, etc.). Will activate.

At the same time, the wireless receiver 30 transmits a control signal by dividing the speaker 60 so as to broadcast an appropriate comment.

In addition, the radio receiver 30 sends a signal to the speaker 60 so that when a vehicle is stopped and students receive a situation to be crossed, a broadcast message suitable for the transmission is transmitted.

On the contrary, when the vehicle, which is in the opposite situation, must be driven, and students receive a situation in which they need to stop walking, a signal is sent to the speaker 60 so that a broadcast message suitable for this is also transmitted.

In addition, if an emergency situation occurs and a student, etc., needs to stop the vehicle by directly pressing the safety bell 10, the contents of stopping the vehicle after about 5 seconds have passed by pressing the safety bell 10 It is to enable the speaker 60 to broadcast. The procedure from thereafter is the same as when the vehicle needs to be stopped using the wireless transmitter 20 described above, so a detailed description thereof will be omitted.
