The storage unit 240 stores various programs necessary for controlling the RFID tag 200, including its ID information uniquely assigned to each RFID tag 200.

The clock 256 generates a signal every predetermined period and provides the signal to the controller 210 so that the controller 210 counts the time and checks whether an ultrasonic signal transmitted from the RFID reader 100 is received for a predetermined time.

The control unit 210 controls the communication with the RFID reader 100 as a block that controls the RFID tag 200 as a whole to check the occupant, and the ultrasonic signal indicating that the signal is a check signal transmitted from the RFID reader 100. When received through the antenna and the ultrasonic receiving unit 254, through the RF transceiver 252 and the antenna transmits an RF signal including its own ID, an ultrasonic signal indicating that the signal for notification transmitted from the RFID reader 100 If is received through the antenna and the ultrasonic receiving unit 254, and outputs the speaker 222, the buzzer 224, the output unit to inform the passengers of the RFID holder.

That is, when the high frequency of the notification signal is received from the RFID reader 100, the controller 210 outputs a sound through the speaker 222 or outputs a warning sound through the buzzer 224.

In addition, the control unit 210 counts a signal input from the clock 256 and if the ultrasonic wave is not received for a predetermined time, the ultrasonic wave is not received in the area where the ultrasonic wave is not received, i.e., the passenger is far from the leader or gets off the bus vehicle. Determining that the area is impossible to receive the signal through the speaker 222 or buzzer 224 to inform that the departure from the leader or aboard the bus vehicle.

In addition, the controller 210 outputs the FM signal through the speaker 222 when the FM signal is input through the RF transceiver 252.

Figure 4 is a flow chart of the passenger check method according to the invention.

As shown in the drawing, the control unit 110 of the RFID reader 100 carried by a pilot on board a bus vehicle counts a signal input from the clock 158, and a predetermined time has elapsed, or a check button is pressed to input a check signal. In operation S402, an ultrasonic signal indicating that the signal is a check signal is transmitted to the RFID tag 200 carried by the passenger through the ultrasonic transmitter 154 and the antenna (S404).

The controller 210 of the RFID tag 200 carried by the passenger receives the ultrasonic signal transmitted from the RFID reader 100 through the antenna and the ultrasonic receiver 254, and analyzes the ultrasonic signal to check the ultrasonic signal. Figure out (S406).

The control unit 210 of the RFID tag 200 confirms that the received signal is for checking and transmits an RF signal including its own ID stored in the storage unit 240 through the RF transceiver 252 and an antenna. It transmits to 100 (S408).

The controller 110 of the RFID reader 100 receives the RF signal transmitted from the RFID tag 200 through the antenna and the RF transceiver 152 and analyzes the RF signal to extract the ID included in the RF signal. (S410).

The control unit 110 of the RFID reader 100 checks whether the extraction ID is in the ID stored in the storage 140, and if the extraction ID is in the stored ID (S412), the passenger of the RFID tag 200 corresponding to the ID. It is determined that the passenger boarded and counted by adding 1 to the number of passengers (S412).

If the extracted ID is not included in the stored ID, 1 is added to the number of passengers, and the ultrasonic signal is transmitted by performing step S404 again.

As a result of repeating the steps S404 to S412 as the total number of passengers stored in the storage unit 240 (S416), if the counted number of passengers is equal to the total number of passengers stored (S418) boarding the bus vehicle It is judged that all the passengers have boarded, and the personnel inspection of the bus vehicle is finished.

However, if the number of occupants counted is different from the total number of occupants stored, that is, if the number of occupants counted is smaller than the total number of occupants stored, the display unit 122 determines that all of the occupants are not on the bus vehicle. Through the speaker 124 and the buzzer 126, a non-passenger is notified to the leader (S420).

As described above, the number of occupants occupied in the bus vehicle can be automatically counted using RFID and an ultrasonic signal with good reflectivity, and if a non-passenger occurs, the instructor can be notified that there is a non-passenger.

As described above, according to the present invention, by automatically counting the number of passengers in the bus vehicle by using the RF signal and the ultrasonic signal transmission and reception between the RFID tag and the RFID reader, it is possible to conveniently check and confirm the number of passengers, Reliable count of passengers counted
