The PLL OSC 106 is a circuit for generating oscillation outputs for the reception circuit 102 and the transmission circuit 107.

  The transmission circuit 107 is for creating a transmission wave 117 in which a low-frequency transmission signal is superimposed on a carrier wave (429 MHz band), and the transmission wave 117 is radiated from the antenna 100 into the air.

  The antenna switching circuit 101 is electronically switched by the transmission / reception switching circuit 110 so that the antenna 100 is connected to the transmission circuit 107 during transmission and the antenna 100 is connected to the reception circuit 102 during reception.

The modulation circuit 108 is for superimposing a low-frequency transmission signal on a carrier wave.
The encoder 109 digitally converts and encrypts the report information from other devices, the sensor control signal, the position information detected by the GPS 113, and the device ID.

  The controller 114 having the CPU 115 operates each circuit including the reception circuit 102 and the transmission circuit 107 of the vehicle-mounted device q in any one of the standby mode, the notification mode, and the relay mode. In the standby mode, the vehicle-mounted device q receives the transmission frequency (fixed) of the remote controller p. In addition, if the received wave 116 (= transmitted wave 91) radiated | emitted by pressing operation of SW90 for remote controls is detected, the crime prevention sensor of the onboard equipment q will be operated.

  In the standby mode, a channel scan for detecting the presence or absence of a carrier having a certain strength or more is performed for each channel at a predetermined time, and an empty channel (a carrier level has a certain strength) that does not detect the received wave 116 other than the transmission frequency of the remote control p. Less channels), a notification channel in which the received signal includes notification information from another vehicle-mounted device q or the like (carrier level is a certain intensity or more), and a use channel in which the received wave 116 of other communication is received (carrier level is lower). The channel scan result and report information from other devices are stored in the memory 111.

During this standby mode, the emergency notification SW 84 of the remote controller p is turned on, and when the beacon receiving circuit 74 of the vehicle-mounted device q near the remote controller p receives the beacon carrier wave 85, the transmission signal is superimposed on the carrier wave from the vehicle-mounted device q. The controller 114 operates in the notification mode for a predetermined time so that the transmission circuit 107, the modulation circuit 108, the encoder 109, and the like operate so that the transmission wave 117 is radiated through an empty channel having a carrier level less than a certain intensity. .
When there is no empty channel with a carrier strength less than a certain strength, carrier sense is performed until the channel becomes free and the notification mode is temporarily suspended from the viewpoint of preventing transmission of a plurality of waves on the same channel.

In the notification mode, the transmission signal is the notification information of the own device including the position information detected by the GPS 113 and the device ID.
When the notification information of the own device or other device is stored in the memory 111, the controller 114 causes each circuit including the transmission circuit 107 to operate in the relay mode for a predetermined time on an empty channel having a carrier level less than a certain intensity. .
If there is no empty channel with a carrier strength less than a certain strength, carrier sense is performed until the channel becomes free and the relay mode is temporarily suspended from the viewpoint of preventing transmission of a plurality of waves on the same channel.
In the relay mode, the transmission signal to be superimposed on the carrier wave is used as notification information stored in the memory 111.

When the ID included in the notification information stored in the memory 111 is a device ID (= remote control ID), the information is the information of the own device, and therefore the position information of the GPS 113 is included in the transmission signal superimposed on the carrier wave. To relay transmission.
Further, when ID ≠ device ID included in the notification information stored in the memory 111, since the notification information is from another device, the location information included in the notification information is relayed and transmitted as it is.

When the beacon receiving circuit 74 of the vehicle-mounted device q receives the beacon carrier wave 85 from the remote controller p, the ID signal of the vehicle-mounted device q identical to the ID signal of the remote controller p is input to the encoder 109. In addition, report information including the position information of the own device (support information that contributes to terminal position specification) detected by the GPS 113 is superimposed on a carrier wave as a transmission signal.
Thereby, the report information including the ID signal and the position information of the own device becomes a transmission wave 117 and is radiated from the antenna 100 to the air.

When the notification channel is detected by the channel scan in the standby mode, and the channel scan result and the notification information from the other device are stored in the memory 111, the transmission circuit 107 is used for a predetermined time in an empty channel with a carrier strength less than a predetermined strength. Each circuit including is operated in the relay mode. If there is no empty channel with a carrier strength less than a certain strength, carrier sense is performed until the channel becomes free and the relay mode is temporarily suspended from the viewpoint of preventing transmission of a plurality of waves on the same channel.
In this relay mode, the controller 114 operates the transmission circuit 107, the modulation circuit 108, the encoder 109, etc., and the transmission signal to be superimposed on the carrier wave is demodulated by the reception circuit 102 and stored in the memory 111. Report information including information. Thereby, the report information including the position information of the other on-vehicle device q becomes a transmission wave 117 and is radiated from the antenna 100 to the air.

The transmission / reception switching circuit 110 supplies power to the transmission circuit 107 and the like related to transmission and transmits a switching signal to the antenna switching circuit 101 during transmission. At the time of reception, power is supplied to the reception circuit 102 and the like related to reception.
The memory 111 is a storage element for storing channel scan results and report information of other devices demodulated by the receiving circuit 102.

  The monitor center r (wireless terminal for message monitoring) includes an antenna 120, a receiving circuit 121, an SQL circuit 123, a decoder 124, a PLL OSC 125, and a controller 126, and receiving means capable of acquiring report information from the vehicle-mounted device q. When the receiving means obtains the report information, the rescue headquarter 127 (rescue organization) and a report circuit 129 (report means) for reporting to the broadcasting station 128 and a power source 130 are provided.

The reception circuit 121 demodulates a low-frequency reception signal from the reception wave 131 (= transmission wave 117) captured by the antenna 120.
The SQL circuit 123 is a circuit for cutting noise when the received signal is no signal.
The decoder 124 decrypts the notification information from the encrypted received signal.
The PLL OSC 125 is a circuit for creating a local oscillation output for the receiving circuit 121. The memory 132 is a storage element for storing notification information demodulated by the receiving circuit 121 or the like.

In the controller 126 having the CPU 133, when the receiving circuit 121 acquires the report information of the other device including the device ID, the report circuit 129 reports the report information to the rescue headquarter 127 (rescue organization) and the broadcasting station 128.
The broadcast station that has received the report superimposes the reported signal 80 decoded by the decoder 95 of the remote control p corresponding to the ID on the broadcast wave.

The emergency call system B of Example 2 has the following advantages.
The owner of the remote control p who became a party (stricken victim, crime victim, accident person) throws in the emergency call SW84 and radiates a beacon carrier wave 85 from the remote control p (beacon terminal), and the vehicle-mounted device q (wireless terminal) The transmission signal 117 is radiated to other vehicle-mounted device q as its own report information including the position information detected by the GPS 113 and the device ID, and the report information is transmitted directly or via a plurality of vehicle-mounted devices q. When the included transmission wave 117 reaches the monitor center r and acquires notification information, the notification circuit 129 notifies the rescue headquarter 127 of the notification information. Since the rescue headquarters 127 that received the report can identify the location where the party is based on the position information detected by the GPS 113 included in the report information, the rescue operation can be performed efficiently.

  Since the 457 kHz beacon carrier wave 85 is radiated from the built-in bar antenna 83 of the remote control p into the air, even if the party carrying the remote control p is buried in rubble or the like, the amount of radio wave attenuation is small. For this reason, it is easy to capture the beacon carrier wave by the vehicle-mounted device q.

  The in-vehicle device q is configured to radiate a transmission wave 117 through a vacant channel with a carrier strength less than a certain strength to report its own report information or relay the report information of another device, and there is no vacant channel Since the notification and relay mode are temporarily suspended until the channel becomes available after performing carrier sense, it is possible to prevent the failure of the notification and relay due to interference, and to extend the notification distance.

When an emergency report sent from the remote controller p carried by the party reaches the monitor center r and the report arrives from the monitor center r to the broadcasting station, the reported signal decoded by the decoder 95 of the remote controller p corresponding to the ID is broadcasted. It is the structure to superimpose.
As a result, the informed LED 96 of the remote control p is lit, so that it can be confirmed by the remote control p carried by the party that the notification information of the own device has been sent.

When the GPS position information is acquired by the remote control p, there may be a case where the GPS position information cannot be acquired due to an obstacle (rubble, collapsed building, etc.). In addition, the cost and size of the remote controller p are increased, and current consumption is increased.
However, since the emergency call system B is configured to relay the position information detected by the GPS 113 of the vehicle-mounted device q without acquiring the position information with the remote controller p, the position information can be reliably transmitted to the rescue headquarters 127. . Further, the manufacturing cost of the remote control p is low, the size can be reduced, and the current consumption can be suppressed.

a. The wireless terminal carried by the owner according to any one of claims 1 to 3, wherein the controller automatically enters a notification mode when the sensor detects that the owner is a party (disaster, victim, or accident). But it ’s okay.

b. The wireless terminal may use the frequency band of IEEE802.16e (WiMAX) of 2.595 GHz to 2.625 GHz.
