Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a seat belt detachment judgment system,

[0001] The present invention relates to a safety belt wear judgment system, and more particularly, to a safety belt wear judgment system for judging whether or not a safety belt has been worn in all cases when it is necessary to wear a safety belt for operation such as a bus or an airplane, &Lt; / RTI >

Due to the nature of high-speed buses and sightseeing buses, many high-speed roads will be driven. In the event of a traffic accident, safety accidents are likely to occur.

A seat belt is provided for each seat so that a passenger wears a seat belt to prevent a passenger from being hit by a collision or sudden jamming due to a traffic accident and suffering a greater injury.

However, when the seat belt is worn, there are many cases where the seat belt is not worn due to inconvenience, and in many cases, the seat belt is released in the middle.

In addition, a device for outputting a warning sound when a seat belt is not worn is widely used for a passenger car, but a device for detecting whether or not the seat belt is worn is not used in the case of a bus on which many passengers are aboard.

In addition, in the case of existing passenger cars, there are not many passengers, so it is possible to immediately wear the seatbelt when the warning sound is heard, and it is often difficult to know whether the alarm sounds due to the noise when there are many passengers on board. There is a problem that the risk of accidents increases because buses are operated without being aware of the non-use.

In addition, since it is difficult to specify which seatbelt is not worn, it is possible to output a large alarm sound so that passengers of all the seats can perceive it, thereby causing noise problems.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a seat belt fastening system which enables a driver or an administrator to wear a seat belt before driving or operating by determining whether a seat belt is worn by a driver or an administrator The purpose is to provide.

The seatbelt wear judging system according to a preferred embodiment of the present invention is characterized in that it comprises a wear information signal which is mounted on a buckle of a seatbelt installed in each seat and judges whether the seatbelt is worn and a predetermined identification information of the seatbelt Buckle switch to output; A control unit for receiving wearing information and unique identification information output by the buckle switch and determining whether all seat belts are worn; And a display unit installed on the driver's seat side and displaying information on whether the seat belt is worn by the control unit.

Preferably, the controller determines whether the seat belt of the seat is not used by determining the unique identification information of the seat belt, and displays the seat belt on the display unit.

Preferably, the display unit includes a seat display corresponding to all of the seats, and the control unit displays only the seat display corresponding to the seat belt that is not yet used.

The control unit may output a warning sound only at an output unit provided in a seat corresponding to the unique identification information of the seatbelt that is not yet used, .

As a result, it is easy to visually confirm whether or not the seat belt of any seat is not worn on a bus with many passengers, so that the driver or the manager can specify and warn the seat.

Accordingly, it is possible to solve the problem of inconveniencing a large-power warning broadcast so that all the seats can hear a warning sound, so that it is possible to output a warning sound with a proper size only by specifying the seat, thereby increasing user convenience.

The passenger detection sensor unit may further include a passenger detection sensor unit for determining whether each passenger is occupied by the passenger detection sensor unit. Preferably, the control unit determines whether the passenger is wearing the passenger sensor only when the passenger is detected by the passenger detection sensor unit .

This makes it possible to determine whether or not the seat belt is worn only when there is a passenger, and it is possible to solve the problem of mistakenly assuming that the seat belt is not worn even when there is no passenger.

According to the preferred embodiment of the present invention as described above, it is easy to visually confirm whether or not the seat belt of any seat is not worn on a bus with many passengers, so that the driver or the manager can warn or warn the seat .

FIGS. 2A and 2B are views for explaining the display unit shown in FIG. 1,
3 is a flow chart for explaining the operation of the seat belt wearing judgment system shown in FIG.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view for explaining a safety belt wearing judgment system according to a preferred embodiment of the present invention.

Referring to FIG. 1, a seat belt wearing determination system 100 according to a preferred embodiment of the present invention includes a control unit 110, a buckle switch 130, a display unit 150, and an output unit 170.

The control unit 110 controls and drives the buckle switch 130, the display unit 150 and the output unit 170 and receives the seat belt wear information and unique identification information from the buckle switch 130, Determine if the seat belt is worn.

The buckle switch 130 is mounted on a buckle of a seat belt installed in each seat, and provides a wearer information signal for determining whether the seat belt is worn and unique identification information of a predetermined seat belt to the control unit 110.

At this time, the wear information signal and the unique identification information are output when the buckle switch 130 is turned on when the seat belt is worn.

The wearable information signal is an 'on' signal when the buckle of the seat belt is coupled, and the unique identification information is an identification ID given to each buckle switch 130. The unique identification information and the seat number are matched, Once identified, the seat number is matched and identified. At this time, the seat number itself can be used as the unique identification number.

The display unit 150 is installed on the driver's seat side to display a seat display corresponding to each seat, so that the seat belt determined by the controller 110 is blinked or brighter, It can be easily grasped visually.

That is, the buckle switch 130 provides wearer information and unique identification information to the controller 110 when the passenger wears the seatbelt, and the controller 110 determines the received unique identification information and the non-received unique identification information .

As shown in FIGS. 2A and 2B, the control unit 110 illuminates or blinks the seat display corresponding to the seat number '15', because the seat matched with the non-received unique identification information corresponds to the seat without the seatbelt So that the driver or the manager can easily grasp the seat for not wearing the seatbelt.

Further, it further preferably includes an output unit 170 for outputting a warning or warning signal for each seat. The output unit 170 is also provided to match with the unique identification information. When it is determined that the seat belt is not worn by the control unit 110, the output unit 170 determines which output unit 170 outputs the warning voice or the caution voice .

As a result of outputting voice with a size that can be confirmed only by the seat without the seatbelt by the output unit 170, the passenger of the other seat does not interfere with the seat so that the convenience of the user can be increased.

Still more preferably, the passenger detection sensor unit 180 further includes a passenger detection sensor unit 180 for sensing whether the passenger is seated or occupied by the seat. The passenger detecting sensor unit 180 may be provided with a load cell in a lower portion where seats are seated to detect a change in load and determine whether a passenger is seated in the seat.

Alternatively, an infrared sensor, an ultrasonic sensor, an optical sensor, or the like may be used to determine whether a passenger is seated in the seat.

At this time, it is preferable that the passenger detection sensor unit 180 is also provided so as to match the unique identification information, so that the seat occupied by the passenger is managed so as to be matched with other information, that is, .

If the passenger is not seated, the seat belt will not be worn, so that the seat will not be judged as a non-seat belt seat if a unique identification number is not provided to the control unit 110 in the seat in which the passenger is not sensed.

On the other hand, when the control unit 110 notifies the ECU () (Electronic Control Unit) controlling the electronic control part such as the engine of the vehicle, the automatic passenger compartment and the ABS, It is also possible to control the vehicle so as not to travel.

That is, when the seat in which the passenger is seated is detected, the control unit 110 prevents the driver from operating the seat when the seat is not worn, so that the safety accident can be prevented in advance, .

According to the preferred embodiment of the present invention, the display unit 150 outputs a print for confirming wearing of the belt once a day after the end of operation.

Referring to FIG. 3, when the seat belt is worn, each of the buckle switches 130 becomes an ON signal, and when the seat belt is worn, The identification number is provided to the control unit 110 (S110) (S120).

The control unit 110 determines the unique identification number provided in step S120 and determines the unique identification number not provided in step S130. That is, the seat of the seat number matched with the unique identification number not provided is not wearing the seat belt.

However, in order to judge whether or not the passenger is seated in the seat before judging that the seat belt is not finally used, the control unit 110 judges the signal of the passenger detection sensor unit 180 of the seat matched with the corresponding unique identification number (S140) (S150).

If it is determined in step S150 that the passenger is seated, the control unit 110 determines that the seat belt is not worn on the seat, outputs a warning or caution sound through the output unit 170, (S160) (S170).

According to the configuration of the present invention, it is determined whether or not a seat belt of a seat occupied by all passengers is seated before the bus vehicle is operated. If there is an unattended seat, it can be easily grasped by the naked eye, The belt can be easily guided so as to be able to slide.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the embodiments described above are in all respects illustrative and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be interpreted as being included in the scope of the present invention.
