The relay communication device A is provided on a guardrail or a soundproof wall on the road side of the traveling path W, or on a side surface of an inner wall of the tunnel H. FIG. 1 shows a case where the relay communication devices A4 to Aj and A104 to Am are provided on the inner wall side surface of the tunnel H.

For example, it is assumed that the traveling path W is located in a forest or the like where a mobile phone cannot be used, a guardrail is provided, and the tunnel H is long enough to make a mobile phone call impossible.

Adjacent relay communicators A are arranged on the side surfaces of the inner wall of the guardrail and the tunnel H at an interval at which they can communicate with each other. The necessary number of relay communication devices A are installed so as to be located in the communication area.

At least one of the relay communicators A

Individual position information set in advance corresponding to each relay communication device is sequentially transmitted by the narrow area communication method.

The emergency information from the relay communicator is finally
It is transmitted from the relay communication device Ak or An at the last end to the notification device D disposed in the emergency communication area by the narrow area communication method (high directional communication).

The notification device D has a reception unit and a transmission unit (to be described later) for wide area communication, and the relay communication device Ak (or A).
In response to the emergency information transmitted from n), at least the position information of the accident vehicle is reported to the emergency center (see FIG. 10) by the wide area communication method.

In FIG. 2, a representative relay communication device A is shown.
Includes a receiving antenna 1, a transmitting antenna 2, a power activation unit 3 and a receiving unit 4 connected to the antenna 1,
The power supply unit 5 includes a transmission unit 5 connected to the antenna 2 and a power supply unit 6 that supplies power to the relay communication device A by activation of the power activation unit 3.

The relay communication device A includes a data processing unit 7 connected to the reception unit 4, the transmission unit 5, and the power supply unit 6, and data (such as a unique word described later) associated with the data processing unit 7. And a sensor 9 for detecting a collision of the vehicle.

When receiving emergency information from another relay communication device, the antenna 1
Start Similarly, the sensor 9 generates emergency information when a vehicle collision accident is detected, and activates the power supply unit 6 via the power supply activation unit 3.

The power supply unit 6 supplies power to the data processing unit 7 and the data storage unit 8 by the activation of the power supply activation unit 3 in response to the emergency information from the antenna 1 or the sensor 9. The data processing unit 7 captures the received data via the receiving unit 4 and outputs emergency information based on the processing of the received data to the transmitting unit 5.

Further, the relay communicator A has reception check means for checking the reception of emergency information from another relay communicator after transmitting the emergency information. When the information is not received, the emergency information is transmitted again.

On the other hand, in FIG. 3, the notifying device D disposed in the emergency communication area includes an antenna 11 for reception, an antenna 12 for transmission, a power activation unit 13 and a reception unit connected to the antenna 11. 14, a transmission unit 15 connected to the antenna 12, and a power supply unit 16 activated by the power activation unit 13 to supply power to the notification device D.

The notification device D includes a receiving unit 14 and a transmitting unit 1
5, a data processing unit 17 connected to the power supply unit 16,
A data storage unit 18 for storing processing data and the like in association with the data processing unit 17 is provided.

The power supply activation unit 13 is activated in response to emergency information transmitted from, for example, the relay communication device Ak (or An) located at the last end, and is supplied from the power supply unit 16 to the data processing unit 17 and the data storage unit. The power supply to 18 is started.

The data processing section 17 drives the transmission section 15 by activating the power supply activation section 13, and notifies the emergency center by a wide area communication method. here,
The transmission frequency from the transmission unit 15 of the notification device D is set to be different from the transmission frequency of the relay communication device A in order to prevent mutual interference.

In FIG. 4, a sensor 9 provided in each relay communication device includes a small generator 20, a ring 21 for integrally rotating a rotating shaft of the generator 20, and a ring 21 at one end.
And a wire 22 wound therearound. Here, the case where a generator is used as the sensor 9 has been described, but an accelerometer or a displacement meter may be used as described above.

The other end of the wire 22 is extended so as not to sag, for example, each of the sensor areas Z1 to Zk in FIG.
And Z101 to Zn are individually covered so as to cover them, and the front end is fixed to a guardrail or the like.

In the tunnel H, for example, an elastic cushioning member having a thickness of several cm is interposed to
2 may be stretched around the side wall of the tunnel. Thus, the impact when the vehicle collides with the guardrail is converted into the movement of the wire 22 and further converted into the rotation of the ring 21 to drive the generator 20.

That is, the shaft (ring 21) of the generator 20
The wire 22 wound around the wire and having one end fixed to the guard rail is always in a stretched state, and generates an induced voltage due to the impact at the time of collision.

Therefore, the relay communication device A is connected to the generator 20
In response to the induced voltage output from the vehicle, a vehicle collision accident can be detected. For example, when the induced voltage of the generator 20 exceeds a predetermined threshold voltage, occurrence of an accident can be detected.

In FIG. 1 to FIG. 4, the sensor 9 in the relay communication device A installed on the road side (guardrail, soundproof wall or side wall of the tunnel wall) of the traveling path W is connected to the vehicle C1 or C2.
When a collision accident on the road side occurs, the impact due to the collision is converted into a voltage signal and detected.

The power supply starting unit 3 in the relay communication device starts the power supply unit 6 in response to the voltage signal from the sensor 9, and sends an emergency signal to another adjacent relay communication device via the data processing unit 7. To transmit unique position information (unique word).

Since the unique word corresponding to the position information is set in advance so as to be different for each relay communication device, the position where the accident has occurred can be specified by referring to the unique word.

The relay communication device that has received the emergency signal (unique word) transmitted from the adjacent relay communication device is activated in response to a reception signal indicating individual position information set for each relay communication device.

The thus activated relay communication device checks the unique word, and if it matches the unique word of the adjacent relay communication device, the position information and the unique word of the relay communication device activated by the collision of the vehicle are replaced with the next word. To the relay communicator adjacent to.

Note that the relay communication device that has been activated once stops the activation state after confirming the signal transmission of the adjacently installed relay communication device. If it cannot be confirmed, the transmitting operation is repeated.

The emergency signal transmitted and transmitted repeatedly in this manner is sent to the notification device D in the emergency communication area where the emergency information can be reported to the emergency center, and the emergency information is finally reported to the emergency center.

If the guardrail on the road is cut off halfway and the distance from the adjacent relay communication device is so large that transmission and reception of the relay communication device become impossible, the sensor 9 of the relay communication device is turned off. It may be detached and installed, and only the main body of the relay communication device may be arranged close to the adjacent relay communication device.

[0062] Thus, the relay communication device can be installed in a place where there is no hindrance to the running of the vehicle, using the function of transmitting only emergency information.

With the above configuration, a vehicle collision accident on the roadside outside the emergency communication area is detected, transmitted to the notification device D via the relay communication device A for performing short-range communication, and emergency signal information is transmitted via the wireless telephone line. The emergency center can be notified.

At this time, each of the relay communicators A causes the adjacent relay communicators to successively transmit the position information and the unique word by the narrow area communication method, and transmits the position information to the reporter D in the emergency communication area. I do.

Next, the specific operation of the first embodiment of the present invention shown in FIGS. 1 to 4 will be described with reference to the flowcharts of FIGS. FIG. 5 is a flowchart showing the operation of the relay communication device A, and FIG. 6 is a flowchart showing the operation of the notification device D.

Now, suppose that the vehicle C1 (see FIG. 1) collides with a guardrail on which the relay communication device A2 is installed.
The wire 22 (see FIG. 4) in the sensor area Z2 is pulled, and an induced voltage is generated from the generator 20 in the sensor 9.

The induced voltage is supplied to the power supply starting unit 3 of the relay communication device A.
(See FIG. 2). Further, when a collision accident occurs in another sensor area, the received data is applied to the power supply activation unit 3 and the reception unit 4 via the antenna 1 of the relay communication device A.

In FIG. 5, first, the power supply starting unit 3 determines whether or not voltage is induced from the sensor 9 (step S).
1) If it is determined that the voltage is induced (that is, YES), the power supply unit 6 is started (turned on) (step S).
2). Thus, power is supplied to the data processing unit 7 and the data storage unit 8.

The data processing unit 7 recognizes that a collision accident has occurred in the sensor area where the relay communication device A is located since there is no data received from the receiving unit 4 at the time of power supply. The data is read out, and transmission data based on the position data is determined (step S3).

On the other hand, if it is determined in step S1 that there is no voltage induction (ie, NO), then the power supply starting unit 3 determines whether the electric field intensity E received from the antenna 1 is equal to or greater than a predetermined value Eo. Is determined (step S4).

If it is determined in step S4 that E <Eo (that is, NO), it is considered that there is no received radio wave or a noise level, and the process returns to the standby state of the power supply starting unit 3 (step S1). On the other hand, E ≧ Eo (that is, YE
If determined to be S), the power supply activation unit 3 turns on the power supply unit 6 (Step S5).

Next, the data processing section 7 determines whether or not the received data input from the receiving section 4 is emergency data indicating the occurrence of an accident (step S6), and determines that the received data is not emergency data (ie, NO). If it is determined, the process returns to step S1.

On the other hand, if it is determined in step S6 that the received data is urgent data (ie, YES), transmission data is determined based on the received data including the location data of the occurrence of the accident (step S7).

When the transmission data is determined in step S3 or S7, the data processing unit 7 transmits the data via the transmission unit 5 (step S8), and determines whether the data is actually transmitted to another adjacent relay communication device. The process shifts to a reception waiting state to check whether or not the request is received (step S9).

First, it is determined whether or not there is reception from an adjacent relay communication device (step S10). If it is determined that there is no reception (ie, NO), the elapsed time of the no reception state is checked. It is determined whether or not the elapsed time T is equal to or longer than a predetermined time To (step S11).

If it is determined in step S11 that T <To (that is, NO), the process returns to step S11, and
The measurement of the elapsed time T is continued.

On the other hand, in step S11, T ≧ To
If the determination is YES (ie, YES), the value of the retry counter K is incremented, and it is determined whether the retry counter K has reached a predetermined number of times Ko or more (step S12).

If it is determined in step S12 that K <Ko (that is, NO), the process returns to step S8, and the data processing section 7 repeats data transmission.

On the other hand, in step S12, K ≧ Ko
If it is determined to be “YES”, it is determined that it is useless even if the data transmission is repeated, and the power is turned off (step S
13), and return to step S1.

If it is determined in step S10 that a signal has been received from another adjacent relay communication device (ie, YES), it is determined that communication has been normally performed.
In step S13, the power is turned off and the process returns.

For example, as described above, the sensor area Z2
When a collision accident occurs, the power supply unit 6 of the relay communication device A2 is activated by the induced voltage from the sensor 9, and the unique word common to each relay communication device and the position data set in advance for each relay communication device are The data is sent from the data storage unit 8 to the data processing unit 7.

The data processing section 7 sends the data sent from the data storage section 8 to the sending section 5 and superimposes the data on the carrier wave and amplifies the data appropriately so as to secure the communication area of the relay communication device A2. 2 to the relay communication devices A1 and A3 installed adjacent to each other.

The relay communicators A1 and A3 are activated by the power supply activation unit 3 when the transmission signal from the relay communicator A2 is received from the antenna 1 and the received radio wave indicates an electric field strength equal to or higher than a predetermined value Eo. .

The activated relay communication devices A1 and A3 are:
The receiving unit 4 removes the carrier from the received signal and sends a data-only signal to the data processing unit 7.

The data processing unit 7 in each of the relay communication devices A1 and A3 checks the received data against the unique word in the data storage unit 8, and determines whether the unique word of the received data matches the unique word in the data storage unit 8. If confirmed, the position data and unique word of the relay communication device A2 are further transmitted to the adjacent relay communication device (for example, A4) via the transmission unit 5.
Send to

At this time, the data processing unit 7 in the relay communication device A2 activated by the first collision occurrence determines that the adjacent relay communication devices A1 and A3 have completed reception and are transmitting data. After confirming from the presence or absence of the input of the receiving unit 4 of A2, the activation is stopped. It should be noted that the relay communication device Ak located at the end stops starting after a certain time from the transmission.

In this way, each relay communication device A repeats transmission and reception, and finally transmits a data signal from relay communication device Ak to notification device D.

When the data signal transmitted from the relay communication device Ak is received from the antenna 11 (see FIG. 3), the notification device D is activated by the power supply activation portion 13 after checking the electric field intensity.

In FIG. 6, first, the power supply activation unit 13
It is determined whether or not the electric field strength E of the received signal is equal to or greater than a predetermined value Eo (step S21). If it is determined that E ≧ Eo (that is, YES), the power supply unit 16 is turned on (step S2).
2).

Next, the data processing unit 17
Is compared with the unique word stored in the data storage unit 18, and the received data is
k is determined (step S2).
3).

In step S23, the relay communication device A
If it is determined that the data is not received data from k (that is, NO), it is regarded as a noise signal, and the process returns to step S21.

On the other hand, if it is determined in step S23 that the received data matches the data from relay communication device Ak (that is, YES), data processing unit 17 determines that the data check has been completed, and The transmission data based on the transmission data is determined (step S24).

Subsequently, the data processing unit 17 outputs data indicating the occurrence of a vehicle accident and the position data to the transmitting unit 15 and notifies the emergency center via the antenna 12 via a wireless telephone line (step S25).

Thereafter, the data processing section 17 shifts to the next data reception waiting state (step S26), and the power supply section 16
Is turned off (step S27), and the process returns.

As described above, the relay communication device A can be installed on the guardrail or the inner wall of the tunnel even on the running path W in a mountain forest or the like where it is difficult to report the vehicle accident. Crew members can be rescued in the event of a C1 or C2 accident.

Embodiment 2 In the first embodiment, the relay communicator A is activated only by the impact on the road side (guard rail) at the time of occurrence of the accident. However, the relay communicator A is installed in consideration of the case where the emergency notification device is installed in the vehicle. In addition, a device for receiving an emergency call from a vehicle may be added.

Hereinafter, a second embodiment of the present invention in which a device for receiving an emergency call from a vehicle is added to a relay communication device will be described with reference to the drawings. FIG. 7 is a configuration diagram schematically showing Embodiment 2 of the present invention, and FIG. 8 is a block diagram showing a specific configuration of the relay communication device in FIG.

In FIG. 7, relay communication devices B1 to Bk, 1
01 to Bn (collectively referred to as “B”), vehicle C11,
C12 and the sensor areas Y1 to Yk correspond to the relay communication device A, the vehicles C1 and C2, and the sensor areas A1 to Ak, respectively, as described above (see FIG. 1).
And the running path W is the same as described above.

Each relay communicator B is provided with a device for receiving an emergency call from the vehicle, and transmits the emergency information from the vehicle C11 to the reporter D in an area where the emergency information can be communicated to the emergency center.
To be transmitted.

In this case, the relay communication devices B4 to B6 and B
104 to 106 are disposed in an area where the guardrail is not installed in the traveling path W. For example, the sensor 9 is not provided, and transmission information from the adjacent relay communication device and emergency information from the vehicle are transmitted. It is assumed that only a receiving device is provided.

A typical relay communication device B is configured as shown in FIG. 8. In FIG. 8, the same components as those described above (see FIG. 2) are denoted by the same reference numerals and detailed description is omitted. I do.

The relay communicator B has an antenna 25 and a receiver 26 for receiving emergency information from the vehicle.
Here, a case where the communication frequency of the emergency information from the vehicle side is different from the transmission frequency from the relay communication device B is shown.

The power supply activating unit 3 in the relay communication device B responds to not only the data received from the other relay communication devices and the induced voltage from the sensor 9 but also the emergency information transmitted from the vehicle. Start.

The data processing unit 27 in the relay communication device B
Responds to the activation of the power supply activation unit 3,
The emergency information is transmitted via the transmission unit 5 while referring to the data in the information.

Next, the operation of the relay communication device B according to the second embodiment of the present invention shown in FIGS. 7 and 8 will be described with reference to the flowchart of FIG. In FIG. 9, steps S1 to S13 are the same processing as described above (see FIG. 5), and thus will not be described in detail here.

In FIG. 7, for example, it is assumed that a vehicle C11 equipped with an emergency notification device (not shown) collides with a vehicle C12 in a traveling road area without a guardrail.
At this time, the emergency notification device mounted on the vehicle C11 determines occurrence of a vehicle accident and transmits emergency information at a frequency different from the frequency of the relay communication device B as illustrated.

The emergency information from the vehicle C11 is, for example,
It is received by the antenna 25 of the relay communication device B107.

As a result, the power supply activation unit 3 in the relay communication device B107 determines in step S4 in FIG.
Is determined, and the electric field strength E is equal to or more than the predetermined value Eo (that is, Y
If (ES) is indicated, the power supply unit 6 is started up to be in a startup state (step S5).

The emergency information becomes data in the receiving section 26 in the relay communication device B 107 and is input to the data processing section 27.

The data processing section 27 checks the received data in cooperation with the data storage section 28. If it is determined in step S6 that the received data is urgent data (that is, YES), then the transmission from the relay communication device B is performed. It is determined whether the data is data (step S36).

In step S36, the emergency data is the transmission data from relay communication device B (ie, YE
If S) is determined, the process proceeds to the above-described transmission data determination process (step S7).

On the other hand, if it is determined that the received emergency data is transmission data from the vehicle (ie, NO),
The process proceeds to the data transmission process (step S8) without processing the received data.

The emergency information transmitted from the vehicle C11 in this manner is reported to the emergency center by the reporting device D in the same manner as described above. Since the operation of the notification device D is the same as that described above (see FIG. 6), the description is omitted here.

As described above, when an emergency notification device is installed in a vehicle, a device for receiving emergency information from the vehicle is provided in the relay communication device B, so that it is difficult to communicate with a traveling path such as a mobile phone. Even if a vehicle accident occurs, the emergency center can be notified of the vehicle accident and the location of the occurrence.

Embodiment 3 In the second embodiment, it is assumed that a device for receiving emergency information from a vehicle is provided in all the relay communication devices B.
May be provided in one unit.

For example, when the transmission output of the emergency information from the vehicle is large, a plurality of relay communication devices B are activated at the same time, and it may be difficult to identify the location where the accident has occurred due to mutual interference.
