Description

  The present invention relates to an emergency contact system for notifying a driver or a conductor of an emergency of a passenger in public transportation such as a bus or a train.

In public transportation, there is a technique in which alarm generation means by sound or light is installed in a vehicle of transportation for emergency situations of passengers due to sudden illness or molesting (for example, see Patent Document 1).
JP 2007-95021 A

However, in the above-described conventional technology, there is a problem in that it is known to the surroundings in order to generate an alarm in the vehicle, and it may be unpleasant to use.
However, there is a demand to notify the conductor etc. of an emergency without being known to the surroundings, and a device capable of responding to such a demand is demanded. In particular, such a demand is strong in a long-distance night bus.

  Therefore, the present invention is composed of a plurality of transmission devices installed in places where the seats of transportation such as buses and trains can be installed and a reception device installed in the driver's seat, etc. A control unit that controls everything, a push button switch, an operation confirmation unit, a transmission unit that can transmit a plurality of times with a time difference, and a battery, and a PROM provided in the control unit A company code, a vehicle number, and a seat number (seat ID) of a transportation facility are set, and the receiving device includes a control unit that controls all the receiving devices, a reception monitor, a reception display unit, a reception notification unit, and a reception unit. The reception monitor is provided with an LCD display device, and the transmission location is displayed by the seat ID transmitted from the transmission device.

  In the present invention as described above, the passenger can transmit the seat number as an ID to the receiving device by pressing the push button switch of the transmitting device installed in the seat or the like in an emergency. And the conductor can immediately know that an emergency has occurred and identify the location of the sender. As a result, the driver or the like can quickly respond to an emergency situation.

  In addition, the seat ID can be set by setting the company code, vehicle number, and seat number in the PROM, and in the traveling vehicle, radio waves are transmitted to other vehicles that are traveling in parallel or passing each other. Even if it arrives, there is no interference.

  Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the embodiment.
FIG. 1A shows a transmitting apparatus, and FIG. 1B shows a receiving apparatus, which are communicated by radio.
For example, as illustrated in FIG. 2, the transmission device 1 is attached to each seat of the night bus (for example, the back of the back of the front seat). The receiving device 2 is provided at a desired location in the driver's seat.
In FIG. 1A, reference numeral 3 denotes a control unit that controls all of the transmission apparatuses. A company code, a vehicle number, and a seat number (seat ID) of the bus company are set in the PROM 4 in the control unit. This company code, etc., sets these conditions in order to prevent erroneous transmission of the traveling vehicle because it is possible that radio waves will reach other vehicles that are traveling in parallel or passing each other. It is.

  Reference numeral 5 denotes an operation LED as an operation confirmation means, 6 denotes a push button switch, 7 denotes a transmission wireless chip as transmission means, and 8 denotes a battery. As a countermeasure against interference, when the pushbutton switch 6 is pressed, transmission is not only performed once, but the control unit 3 extends the time interval to 2 seconds, 4 seconds, 9 seconds, 11 seconds, 17 seconds, for example. The transmission is repeated and the power is turned off after five transmissions. Further, the transmission interval is shifted little by little with reference to the seat ID so that interference does not occur when there are a plurality of transmissions.

  In FIG.1 (b), 9 is a control part and controls all the receivers. Reference numeral 10 denotes a reception monitor, which has an LCD display device 11. As shown in FIG. 3, this LCD display device can simultaneously display a plurality of seat numbers, in this embodiment, 10 (10 seats). Thus, the transmitted seat is displayed, and the driver and the conductor can specify the transmitted seat.

Reference numeral 12 denotes an LED as a reception display unit, and reference numeral 13 denotes a buzzer as a reception notification unit. 14 is a transformation module, 15 is a reception wireless chip as a receiving means, and 16 is a power switch, which is connected to an external power source.
Next, the operation of the above-described configuration will be described.
The power switch 16 of the receiving device is turned on and set to a receivable state.

A display such as “emergency call” is displayed on the LCD display device 11.
In the above state, when the passenger presses the push button switch 6 (for example, 9C) of the nearby transmission device 1 in an emergency, as described above, transmission is repeated multiple times at intervals from the transmission means 7 and transmitted. It will be turned off later. At this time, since the passenger has anxiety as to whether or not the transmission has been performed, the operation LED 5 is lit for about 1 second.

At the same time, the buzzer 13 of the reception notification means of the receiving device 2 sounds for about 1 second to notify the driver and the like, and the LED 12 of the reception display means is turned on, and the lighting state continues.
Furthermore, the seat ID (for example, 9C) of the operated transmission device (seat) is displayed on the LCD display device 11, and the display state continues.
As described above, the driver and the like can know that an emergency has occurred and at which seat.

Further, when the push button switch 6 (for example, 4A) of the next transmission device is pressed, the buzzer 12 of the reception notification unit sounds and the LED 12 of the reception display unit is turned on and the LCD display device 11 is turned on as described above. Along with the display, the seat ID (4A) of the operated transmission device is displayed.
The lighting of the LED 12 of the reception display means and the display of the LCD display device 11 are cleared when the driver or the like turns off the power switch 16.

In the above description, the transmitter is provided only in the seat. However, the transmission device is not necessarily limited to the seat, and can be installed anywhere as long as the passenger can use it. It is specified and displayed on the LCD display device.
According to the embodiment described above, the passenger can transmit the seat number as an ID to the receiving device by pressing the push button switch of the transmitting device installed in the seat or the like in the event of an emergency. And the conductor can immediately know that an emergency has occurred and identify the sender's location. As a result, the driver or the like can quickly respond.

Further, by repeatedly transmitting a plurality of times by operating one push button switch, there is an effect that transmission can be reliably performed to the receiving device in the traveling vehicle.
Furthermore, by changing the time of repeated transmission according to the ID, it is possible to prevent interference of each transmission device, and it is possible to simultaneously transmit a plurality of passengers.
In the above description, the long distance bus has been described as an example. However, the present invention can prevent interference by transmitting the company code, the vehicle code, and the seat number as an ID. It is compatible with trains and other transportation systems where vehicles pass in parallel.
