It is assumed that activation of the switch deactivation button is a default state, and it is assumed that a switch deactivation signal is generated when the switch deactivation button is operated.

The operation of the communication device between the crew and passengers in the bus according to the preferred embodiment of the present invention configured as described above will be described in detail as follows.

If a passenger on the bus has a request to deliver to the flight attendant (driver), the disembarkation bell device (100) installed closest to the passenger ), operate the appropriate button and deliver the requested or delivered items to the crew.

For example, if you want to get off at this stop, press the get-off bell button 101 provided in the switch module 110 .

In addition, when an emergency situation occurs in the vehicle or an emergency situation occurs in the vehicle and the crew wants to notify it, the emergency situation notification button 104 provided in the switch module 110 is pressed.

Similarly, when requesting air conditioning or heating to the crew member, the air conditioning request button 103 provided in the switch module 110 is pressed.

When the air-conditioning request button 103, the get-off bell button 101, or the emergency notification button 104 is pressed, the button recognition unit 106 recognizes this and generates button information corresponding to the button as a get-off bell information. and transmits it to the button information output unit 108 .

That is, the button recognition unit 106 generates the button information as getting off bell information, including location information on which itself (meaning a get off bell device) is installed or identification information (ID) for identifying itself. It is assumed that the installation location information or identification information is stored in the internal memory.

When the button information output unit 108 receives disembarkation bell information including button information and identification information corresponding to the button operated by the passenger, it transmits the disembarkation bell information in a preset communication format with the crew speaker device 200 do. For example, the alighting bell information is transmitted through a wired communication method such as RS-485, or the alighting bell information is made into a short-range wireless packet in a short-range wireless communication format such as Bluetooth and transmitted to the crew speaker device 200 .

The disembarkation bell information receiving unit 202 of the crew speaker device 200 receives the disembarkation bell information transmitted from the disembarkation bell device 100 and transmits it to the control unit 204 .

The control unit 204 transmits the delivered disembarkation bell information to the disembarkation bell position recognizing unit 205 , and the disembarking bell position recognizing unit 205 recognizes the location information of the disembarking bell apparatus 100 from the transmitted disembarking bell information. do. That is, using the installation location information or identification information included in the getting off bell information, the location where the corresponding getting off bell device is installed is recognized.

The disembarking bell position information recognized in this way is transmitted to the control unit 204, and the control unit 204 uses the disembarking bell position information as the passenger position information to display the passenger position information and the manipulated button information together on the passenger position display unit 206. . That is, it is determined where the passenger has operated the alighting bell, and which button the passenger has pressed, the passenger location information and the operation button information are transmitted together to the passenger location display unit 206 . Here, the operation button information is included in the getting off bell information transmitted from the getting off bell device. Accordingly, the passenger location display unit 206 displays information about the location where the alighting bell is operated and information about the operated button. Here, as a method of displaying the position of the passenger, by superimposing the disembarkation bell position information on the bus shape drawing, the flight attendant easily recognizes which position the passenger operated the disembarking bell and which button was operated while driving. Here, the reason for recognizing the location of the passenger who operated the alighting bell is to recognize the location of the passenger when the emergency notification button is operated, and to quickly respond accordingly.

In addition, the control unit 204 generates a button signal and transmits it to the button signal output unit 207 while displaying the passenger position according to the disembarkation bell information and which button has been operated as described above.

The button signal output unit 207 converts the transmitted button signal into a sound signal and transmits it through the speaker 201 .

Therefore, when the button sound is transmitted through the speaker 201 while driving, the flight attendant recognizes which position the passenger has operated the alighting bell and what button is requested through the passenger location display unit 206, and responds accordingly. Take action.

Here, it is preferable that the button sound be transmitted separately from the get-off bell sound and other sounds. Normally, when the disembarkation bell sounds, the flight attendant does not need to check the passenger's location information, and just stops at the bus stop as before. Therefore, it is desirable to differentiate the sound of the disembarking bell button and the sound of other buttons so that the flight attendant can focus on driving and eliminate the inconvenience of checking the passenger's location whenever a button sound is generated.

As a result, the passenger can conveniently deliver the information requested from the flight attendant to the flight attendant by using the get-off bell device at his/her location without moving to the driver's seat where the flight attendant is.

On the other hand, the passenger can simply communicate with the crew while the bus is running, requests, deliveries, emergency situations, etc. through voice without approaching the crew at the current location.

For example, the passenger presses the microphone button 102 provided in the switch module 110 when a matter to be transmitted by voice with the crew is generated. When the microphone button 102 is pressed, the button recognition unit 106 recognizes which button has been pressed, and generates button information corresponding to the button as getting off bell information and transmits it to the button information output unit 108 .

That is, the button recognizer 106 generates the microphone button information as the alighting bell information, including location information on which the button recognizer 106 is installed (meaning an alighting bell device) or identification information (ID) for identifying itself.

When the button information output unit 108 receives disembarkation bell information including button information and identification information corresponding to the button operated by the passenger, it transmits the disembarkation bell information in a preset communication format with the crew speaker device 200 do.

The disembarkation bell information receiving unit 202 of the crew speaker device 200 receives the disembarkation bell information transmitted from the disembarkation bell device 100 and transmits it to the control unit 204 .

The control unit 204 transmits the delivered disembarkation bell information to the disembarkation bell position recognizing unit 205 , and the disembarking bell position recognizing unit 205 recognizes the location information of the disembarking bell apparatus 100 from the transmitted disembarking bell information. do. That is, using the installation location information or identification information included in the getting off bell information, the location where the corresponding getting off bell device is installed is recognized.

The disembarking bell position information recognized in this way is transmitted to the control unit 204, and the control unit 204 uses the disembarking bell position information as the passenger position information to display the passenger position information and the manipulated button information together on the passenger position display unit 206. . That is, the location of the passenger who operated the alighting bell is determined, which button the passenger pressed, and the passenger location information and the operation button information are transmitted together to the passenger location display unit 206 . Here, the operation button information is included in the alighting bell information transmitted from the alighting bell device. Accordingly, the passenger location display unit 206 displays information about the location where the alighting bell is operated and information about the operated button.

In addition, the control unit 204 generates a button signal and transmits it to the button signal output unit 207 while displaying the passenger position according to the disembarkation bell information and which button has been operated as described above.

The button signal output unit 207 converts the transmitted button signal into a sound signal and transmits it through the speaker 201 .

Accordingly, when a button sound is transmitted through the speaker 201 while driving, the flight attendant can recognize through the passenger location display unit 206 at which location the passenger manipulated the alighting bell and what button is requested.

When the flight attendant recognizes that the passenger has operated the microphone button through the above process and wants to activate the microphone button 102 to listen to the passenger's voice, no action is required. If you do not want to listen to the passenger's voice request because it is perceived as an obstacle to driving, you operate a separately installed switch deactivation button.

When the switch deactivation button is operated, the control unit 204 generates a switch deactivation control command, and when the switch deactivation button is not operated, the control unit 204 generates a switch activation control command and transmits it to the switch module control unit 203 .

The switch module control unit 203 converts the switch activation control command or switch deactivation control command generated by the control unit 204 into a communication format preset with the alighting bell apparatus 100 and transmits the converted switch activation control command or the switch deactivation control command to the alighting bell apparatus 100 .

The switch module control command receiving unit 109 of the alighting bell device 100 receives it and transmits it to the button recognition unit 106 .

When the received switch control command is a switch deactivation control command, the button recognition unit 106 deactivates the microphone button 102 and ignores the passenger voice input from the microphone button 102 .

On the other hand, if the received switch control command is a switch activation control command, a specific power is supplied to the microphone button 102 so that the passenger recognizes that the microphone is activated. Here, a light emitting diode is mounted on the microphone button 102, and the light emitting diode is turned on only when a switch activation control command is commanded, so that the passenger recognizes that the crew is in a state where the crew can hear the voice.

When the light emitting diode is turned on on the microphone button 102 of the alighting bell device 100, the passenger speaks a voice to be transmitted to the crew.

The passenger's voice is input through a microphone integrated into the microphone button 102 , processed by the voice processing unit 107 under the control of the button recognition unit 106 , and then transmitted to the button information output unit 108 .

The button information output unit 108 combines the alighting bell information transmitted from the button recognition unit 106 and the voice information transmitted from the voice processing unit 107 and transmits it to the crew speaker device 200 as button information.

The disembarkation bell information receiving unit 202 of the crew speaker device 200 receives it and transmits it to the control unit 204, and the control unit 204 extracts it when the disembarking bell information to be transmitted includes a voice signal and extracts it to the voice output unit ( 208).

The audio output unit 208 amplifies the audio signal extracted from the control unit 204 and transmitted to a set level, and transmits it to the outside through the speaker 201, so that the crew hears the voice of the passenger from the driver's seat. .

Thereafter, by taking appropriate measures according to the request of the passenger, the flight attendant may promote safe driving while satisfying the passenger's request.

In addition, in the event that a passenger needs to deliver something to the crew, there is no need to move to the driver's seat, and a specific situation can be communicated or requested by a button through the exit bell device close to the current location, or a specific situation can be communicated or requested to the crew member through voice. When communicating with the crew on the bus during operation, passengers do not need to move, so safety accidents can be prevented.
