And by making it possible to respond, it is possible to quickly respond to a dangerous situation, as well as to prevent the occurrence of accidents IoT-based children's school vehicle integrated safety management support system.

In general, children's school vehicles are those operated by children's facilities such as daycare centers, kindergartens, elementary schools, special schools, academies, and physical education facilities for children under the age of 13.

Because these schools often delay more than the originally set arrival time due to various road conditions, emphasis is on getting off quickly according to the class time, so it is often difficult to get people off at once.

Since the main user of the school vehicle is a child, special attention is required when the vehicle stops and starts, when children get on and off the vehicle, or when the vehicle is in operation and after the vehicle is finished.

That is, in the process of commencing after the school vehicle starts to stop, children in blind spots have not been found, and accidents have occurred frequently, and sometimes there are children who have not gotten off in the school vehicle. Not only are they not aware, there are cases where children are left intact in heat waves and are threatened with life.

Therefore, there is an urgent need for a method to automatically detect personnel on boarding and disembarking children and notify the result to the administrator's wireless terminal in advance to prevent accidents. In addition, there is an urgent need for a method to prevent accidents by detecting children in blind spots in advance.

The accident prevention of children's school vehicles has been developed with people-centered reinforcement of the will and effort of the child, but it is expected to have a complete accident prevention as there are practical limitations to limiting the number of people or taking preventive efforts in limited time. It was difficult to do.

Therefore, although some functions of safety devices and systems have been developed and used, they are fragmentary, simple, and auxiliary, and are still insufficient to prevent various accidents effectively and effectively.

Due to the long time, it is very inefficient due to the characteristics of a school vehicle that needs to be busy within a limited time, and it is difficult to obtain reliable information in the event of malfunction or failure of the seat or seat belt fastening sensor, and these increase the cost for installation in the vehicle. There are disadvantages.

On the other hand, in Korean Registered Patent Publication No. 10-1801179 (hereinafter referred to as'Prior Document 5'), a safety bar for a children's school bus is known by providing a safety bar in a vehicle to block children from crossing the road after getting off the vehicle.

However, in the case of the prior document 5, a child is moved to the front part of the vehicle after getting off, and a method for preventing entry of other vehicles into the boarding/unloading area is not directly presented, but even if a safety bar is installed on the right side of the front part of the vehicle. By circumventing this, it is difficult to prevent crossing close to the blind spot on the front of the school vehicle, and in this case, there is a problem that a driver of another vehicle operating due to a limited viewing angle cannot find a child and respond appropriately.

Further, when an object is detected by the object detection sensor 263, the safety device integrated controller 200 transmits a control signal to the integrated terminal 100, and sounds a warning through the speaker 160 provided in the integrated terminal 100. Allows it to be sent out. The driver may recognize that there is an object, a child, or a person around the school vehicle 500 through a warning sound.

At this time, the warning sound is also sent out differentially according to the danger level. This is associated with the icon color described above. Here, the difference of the warning sounds can be set as the volume of the warning sounds or the transmission interval.

Figure 2 is a block diagram showing in detail the integrated terminal 100 in the IoT-based children's school vehicle integrated safety management support system according to an embodiment of the present invention, Figure 6 is an IoT-based children's school vehicle integrated safety management according to an embodiment of the present invention It is a diagram showing the on/off detection in the support system.

6 shows an example of a screen displayed on the display 140 of the integrated terminal 100 in the process of children getting on and off the school vehicle 500.

On the display 140, a seat (seat) is displayed as it is in the arrangement form of the commuting vehicle 500, and an icon indicates whether a child is seated and whether a seat belt is worn for each seat. In addition, the number of seating and seating and the number of seat belts currently displayed are displayed numerically on the lower portion of the display 140. If there is a difference between the number of passengers and the number of seating or wearing seat belts, the speaker 160 outputs a warning sound suitable for the situation.

When the difference between the number of seat belts and the number of seating occupants occurs as shown in the example of FIG. 6, the message “Please check the seat belt.” is displayed on the lower portion of the display 140, and a voice is transmitted through the speaker 160. . In this case, the driver can go to a location where there is a child who is not wearing a seat belt, and can help wear the seat belt. Thus, the driver of the school vehicle 500 can not only recognize the current situation reliably, but also make an appropriate response to the situation, thereby preventing an accident from occurring.

Figure 4 is a block diagram showing the school vehicle 500 in detail in the IoT-based children's school vehicle integrated safety management support system according to an embodiment of the present invention, Figure 7 is an IoT-based children school vehicle integrated safety management according to an embodiment of the present invention A diagram showing the operation of the safety bar 230 installed on the rear side of the school vehicle 500 in the support system, FIG. 8 shows the school vehicle 500 in the IoT-based children's school vehicle integrated safety management support system according to an embodiment of the present invention It is a view showing the operation of the safety bar 230 installed on the front side of the. In Figure 7 (a) shows a view seen from the rear of the school vehicle 500.

When the school vehicle 500 is completely stopped, the safety device integrated controller 200 unfolds the safety bar 230 and the notification sign 240 that are folded. At this time, whether the school vehicle 500 is stopped may be determined by the acceleration sensor 264.

7 shows that the safety bar 230 and the notification sign 240 installed on the rear side of the school vehicle 500 are unfolded. By unfolding the safety bar 230 and the notification sign 240, it is possible to inform a motorcycle or other vehicle proceeding from the rear of the school vehicle 500 that a child is getting off or riding. In addition, when the child getting off the school vehicle 500 moves to the rear of the school vehicle 500, it acts as an obstacle. So, it prevents the collision accident that may occur when the child moves to the rear of the school vehicle 500.

8 shows that the safety bar 230 and the notification sign 240 are unfolded on the front side of the school vehicle 500. As the safety bar 230 and the notification sign 240 are extended toward the front, it is possible to inform a motorcycle or other vehicle that runs in parallel with the school vehicle 500 that a child is getting off or riding. In addition, since the child getting off the school vehicle 500 moves toward the front of the school vehicle 500, the safety bar 230 must be moved to the side, so a motorcycle or other vehicle that runs in parallel with the school vehicle 500 It can be easily recognized even from a distance. So, it prevents a collision accident that may occur when a child moves in front of the school vehicle 500.

9 is a flow chart showing the operation process of the school vehicle 500 in the IoT-based integrated safety management support system for children school vehicles according to an embodiment of the present invention.

The route registration step (S1) is a step in which a vehicle operation route configured with reference to a child's home address from a facility official is registered with the management server before the school vehicle is operated.

The school reservation step (S2) is a step in which a parent who is a user of a school vehicle reserves a date, a route, and a place for children to get on and off through the app of the smart device, or changes and registers the reserved details. At this time, the app is provided for smart devices and is configured to communicate with the management server. On the other hand, through the school reservation step (S2) it is possible to calculate the number of people who want to use the school vehicle.

In the downloading step (S3), the driver downloads the reservation information of the vehicle use including the vehicle operation route map and the number of reservations reserved by the school reservation step (S2) with the integrated terminal before the driver drives the school vehicle, and the integrated terminal It is a step to mark on.

At this time, steps S1 and S2 are performed before the operation of the school vehicle, and steps S3 are performed when the operation of the school vehicle starts. After step S3, the driver drives the school vehicle to move the place for getting on and off for each child in sequence according to the determined route. At this time, the driving route map is automatically displayed on the integrated terminal when the school vehicle starts to operate after departure.

The boarding personnel check step (S4) is performed in a state where the school vehicle stops at the place of getting on and off. When a child carrying an RFID tag gets on a school vehicle, the child is automatically recognized through the RFID logic installed in the school vehicle and counted. In this case, when the RFID tag is not smiled or cannot be recognized due to a temporary error, a manual input unit may be provided in the passenger's app and the integrated terminal's app to allow the passenger to be manually recognized. The boarding personnel check step (S4) is a step of calculating the number of boarding persons by adding the automatically recognized boarding persons and the manually recognized boarding persons, and comparing the number of persons booked in the school reservation step (S2).

After the boarding personnel check step (S4), the operation information transmission step of transmitting the start of the commuting vehicle, the arrival and departure of each boarding place, and the end of the vehicle operation to the user or registered guardian and facility related terminal, GPS module and map information It may further include a step of providing driving information to provide a real-time driving trajectory of the vehicle and a current location and expected arrival time to a user or registered guardians and facility personnel. For the sake of convenience, the process of transmission and input to a user's terminal, such as a user, a facility related person, a guardian, and a teacher, will be described directly as a party without the terminal.

Through the operation information transmission step and operation information provision step, users or registered guardians and facility personnel can monitor and verify that the school vehicle is operating properly.

The getting on/off step (S5) is a step of wirelessly transmitting the place name of getting on and off and the information of the getting on and off children to the smart devices of the corresponding parents when the children get on and off for each place. At this time, this information is also transmitted to the integrated terminal through wired or wireless.

The seating information display step (S6) detects seating personnel by seating sensors that are installed on seats in the school vehicle and detect seating of children and whether or not seat belts are fastened in the seated state, and the calculated seating information is integrated through wired or wireless. It is transmitted to the terminal and the integrated terminal displays seating information on the display. The driver can check whether the child is seated properly and is wearing the seat belt properly through the seating information displayed on the display.

The non-defective confirmation step (S7) compares whether the number of passengers checked in the boarding personnel check step (S4) and the number of seating information displayed in the seating information display step (S6) are consistent, after the operation of the school vehicle is completed on the designated route. This step is to indicate the presence or absence of unloading personnel on the integrated terminal. In more detail, as children getting on the vehicle get off, the RFID tag automatically enters the getting-off information into the RFID reader, and children who do not have an RFID tag or have an erroneous RFID tag directly enter the getting-off information using the manual input unit. Check the number of people getting off and compare the number of passengers on board with seating and seat belt fastening to determine the number of people remaining. At this time, the number of boarding passengers is likely to be the same as the number of seat belts, so the number of boarding passengers and the number of getting off passengers are often contrasted, but since they may be different, it is possible to check the remaining number of children more strictly.

In the operation information storage step (S8), when the operation of the school vehicle is normally completed, the operation termination button is operated through the integrated terminal, and information related to the children's boarding and departure and the operation information of the school vehicle for each route are generated by operating the operation end button through the integrated terminal. This is the step of transferring and storing to the management server. The operation end button may be formed on the display or a physical button near the integrated terminal. On the other hand, the driver may switch the act of turning off the start of the school vehicle by operating the end button.

The wake-up sound transmission step (S21) is a step of transmitting the wake-up sound for a predetermined time to the horn installed in the school vehicle through the integrated controller of the safety device after the operation information storage step (S8). This can wake up the sleeping child in the school vehicle, or inform you that the school vehicle has arrived at its destination if there are unloaded personnel.

The confirmation encouragement step (S22) is a step of transmitting a guide voice for the driver to check the camera image after the weather sound transmission step (S21). Upon hearing the guide voice, the driver can check whether there are unloaded personnel by operating the integrated terminal and checking the image taken with the internal camera. The camera image confirmation guide voice can be expressed in various languages.

The step of checking the image (S23) is a step in which the driver operates the integrated terminal, moves the internal camera installed so as to be provided with a rail and a driving unit at the ceiling in the commuting vehicle to check the image information of the internal camera with the integrated terminal. The driver can operate the integrated terminal and move the internal camera to check the presence or absence of unloaded children on the entire seat of the school vehicle. In addition, the image information of the empty seat is pre-stored so that when the child is in the seat or hidden under the seat, both images can be compared and checked automatically.

The integrated terminal app termination step (S24) is a step for informing the management server and facility personnel of the video confirmation step (S23) if the video confirmation step (S23) is not performed by the driver. When the video verification step (S23) is omitted and the app of the integrated terminal is terminated, the horn transmits a warning sound in the attending vehicle for 1 to 3 minutes. At the same time, the integrated terminal transmits abnormal termination information to the management server through wired/wireless communication. In addition, the abnormal termination information is sent to the facility personnel in a text message to notify them that the child has not been checked. So facility personnel can contact the driver or take other safety measures.

The power off step (S44) is a step of supplying power to the integrated controller of the safety device and the integrated terminal, the internal camera and the window opening and closing device for a predetermined time by a timer, and then turning off the power. At this time, the power-off step (S44) is performed after the integrated terminal app termination step (S24).

On the other hand, turning off the power after supplying power to the devices and integrated terminals connected to the safety controller for a certain period of time while the school vehicle is in operation is not checked by the internal camera when the integrated terminal app is closed. In the event that it is not, or is neglected, it is for controlling the temperature inside the school vehicle through the temperature transmission step (S31) and the window opening and closing step (S32) and the emergency situation detection step (S41). . In addition, it is to reduce excessive power consumption that may occur due to re-supply after power off.

The temperature transmission step (S31) is a step for measuring the temperature in the vehicle with a temperature sensor installed in the school vehicle and transmitting the temperature information to the safety controller integrated controller. The temperature sensor continues to measure until the power is cut off.

The window opening and closing step (S32) is a step of automatically opening and closing the window according to a preset temperature when temperature information is received from the integrated controller of the safety device. If the proper temperature in the commuting vehicle is set to 22 degrees by the integrated controller of the safety device, and the temperature sensor is measured to be 22 degrees or higher, the window opening and closing device opens the window of the commuting vehicle so that the room temperature can decrease. Through this, it is possible to prevent the risk of suffocation of unloaded children who are left in school vehicles.

The emergency notification step (S41) is a step of detecting children unloaded in the school vehicle through a plurality of sound detection sensors and object detection sensors installed in the school vehicle, or detecting other emergency situations and transmitting them to the safety controller integrated controller by wire or wireless. .

In the emergency text sending step (S42), when a child or child under an emergency situation is detected by a sound sensor and an object sensor, the internal camera is automatically driven and an emergency contact text is sent to the facility personnel and the parents of the child. It is a step. In addition, it transmits emergency contact texts, flashes the emergency lights of the school vehicle, and activates the horn to spread it so that external people can be aware of the emergency.

The emergency video verification step (S43) is a step of allowing a user of a facility and a parent or child who has received an emergency contact text to check the situation in the school vehicle through the app of the smart device.

The attendance confirmation step (S25) is a step in which a text is transmitted as a result of attendance confirmation to a user such as a parent and a registered guardian when a child enters the facility and checks attendance after the route operation of the school vehicle is finished. At this time, attendance check can be checked by teachers and facility personnel through the PC app and smart device app.

On the other hand, before the unloading check step (S7), the warning light flashing step (S11), the safety guide starting step (S12), and the safety guide home position step (S13) may be performed.

The warning light flashing step (S11) is a step in which the safety device integrated controller flashes the warning light provided on the school vehicle in yellow when the driver presses the vehicle stop warning button on the integrated terminal while the school vehicle is running. Through this, the vehicle or people around the school vehicle are notified of the stop of the school vehicle. So you can call attention to the surrounding cars or people to be alert. At this time, the vehicle stop notice button may be formed as a physical button on the integrated terminal, or may be formed as a button displayed on the display.

The guide starting step (S12) is a step in which the door is opened and closed after the school vehicle is completely stopped, and the vehicle or people around the school vehicle are notified that the child is getting off, and at the same time, the child getting off is blocked from passing behind or in front of the vehicle. Whether the door is opened or closed is detected by a door detection sensor installed on the door. When the door is detected by the door detection sensor, the integrated safety device controller automatically turns the alarm lamp of the commuting vehicle from yellow to red and blinks, and at the same time, the warning sign and the safety bar that informs the surrounding vehicles and people of the child are automatically leveled. do. At this time, the notification sign and the safety bar are installed on the front left side and the rear right side of the vehicle, respectively. And the safety bar is rotated horizontally in a vertical and horizontal state, and includes a method of protruding from the body.

The notification sign serves to inform nearby vehicles and people that children are getting off the school vehicle. The safety bar is spaced from 70 to 80 cm from the ground to the height of the chest of the child when leveled. The safety bar acts as an obstacle that prevents movement when the child tries to pass behind or in front of the vehicle. Accordingly, since the movement of the child to the rear or front of the vehicle is blocked by the safety bar, a collision accident caused by a motorcycle or vehicle passing around the school vehicle can be prevented.

The safety guide home position step (S13) is a step in which when the door of the commuting vehicle is closed, the notification sign in the horizontal state and the safety bar are returned to the home position. At this time, when the closing of the door is detected by the door detection sensor, the safety bar that is started horizontally rotates vertically and horizontally, and when it protrudes, it is inserted. In addition, the child boarding signs are rotated to return to the horizontal position. In addition, the warning light flashes automatically from red to yellow.

The sensing information transmission step (S51) is a step of transmitting the object detection information obtained by the camera installed on the upper side of the outer 4 side of the school vehicle and the object detection sensor installed on the lower side of the outer 4 side of the school vehicle via wired/wireless communication to the integrated terminal.

The terminal display step S52 displays the camera image information and the image of the school vehicle in the form of an around view, and the object detection information is displayed on the display in the form of an icon.

The sensing information display step (S53) is a step of fusing and displaying the above-described around-view image and object detection information on the display of the integrated terminal in conformity with the sensor mounting position of the school vehicle. At this time, the object detection information displays an alarm sound through the color display, flashing speed, and horn of the icon for each danger level according to the detection distance.

The alarm sound transmission stop step (S54) is a step of stopping the transmission of the alarm sound when the school vehicle proceeds at a speed of 20 km/h or more per hour. When the school vehicle proceeds at a speed of 20Km/h or more per hour, object detection by the object detection sensor is stopped. At this time, the speed of the school vehicle can be measured by the acceleration sensor and the GPS module.

The alarm sound transmission step (S55) is a step in which the safety controller integrated controller transmits a warning sound or a warning sound to the outside using a horn when shifting to reverse a school vehicle. A proximity or object detection sensor is attached to the shift lever portion of the commuting vehicle to check for shifting.

The vehicle braking step (S61) is a step of preventing overspeed when the school vehicle moves backward after the alarm sound transmission step (S55 ). To this end, an automatic braking device is installed in the vehicle braking part of the school vehicle. When the forward or reverse movement is detected at a speed of 10Km/h or more by the acceleration sensor provided in the school vehicle, the integrated controller of the safety device activates the automatic braking system to brake the school vehicle to stop. This prevents accidents that can occur when reversing at excessive speed.

The door opening prevention step S71 is a step of preventing the door from opening when the school vehicle moves forward or backward after the alarm sound transmission step S55. When a forward or reverse movement is detected at a speed of 1 Km/h or more by the acceleration sensor provided in the school vehicle, the integrated controller of the safety device determines the school vehicle as an unstopped state and prevents the door from opening. At this time, the integrated controller of the safety device controls the opening and closing of the door by controlling the door opening and closing device provided in the door.

The door closing prevention step (S72) is a step of preventing the door from closing when a child is detected when getting on and off while the door is open.

That is, the integrated controller for safety devices controls the door opening/closing device so that the door is opened when a child, a driver, or a person is detected in the detection areas of various types of object detection sensors installed on one side inside the door and one side outside the door.

The vehicle stopping step S73 is a step of braking to stop the school vehicle by operating an automatic braking device when the movement of the school vehicle is detected while the door of the school vehicle is opened. When the door is opened by the door opening/closing device, the door open icon flashes on the integrated terminal. When the movement of the vehicle is detected by the acceleration sensor in the door open state, the integrated controller for safety devices activates the horn to alert the driver and the child of the dangerous situation. In addition, when the speed of the school vehicle is detected by the acceleration sensor at 1Km/h or more, the integrated controller of the safety device activates the automatic braking system to completely stop the school vehicle. Therefore, it is possible to prevent a fall accident that may occur while operating while the door is open.
