BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency call system, and more particularly, to an emergency call system for giving emergency information to a vehicle occupant. 2. Description of the Related Art Conventionally, a vehicle has a VDT device such as a CRT display, and the VDT device displays the state of each part of the vehicle, displays a road map and the current position, and displays a TV broadcast on-vehicle image display device. It has been known. On the other hand, when an emergency warning broadcast such as an earthquake or tsunami is transmitted,
There is known an emergency alert broadcast receiver that operates to receive it and automatically play the emergency alert broadcast from a speaker. There is also known a telephone security system that automatically telephones personal alarm information to a predetermined contact point (for example, fire at home, gas leak, trespass, etc.). Problems of Prior Art It is conceivable to combine a conventional vehicle-mounted image display device and an emergency alert broadcast receiver to automatically receive an emergency alert broadcast and display the TV direction on the VDT device. However, in the conventional emergency alert broadcast receiver, when there is an emergency alert broadcast, the VDT device is always activated. Therefore, for example, the VDT device is activated even when no one is in the car, and the battery is useless. There is a problem that leads to the consumption of. On the other hand, since the telephone call in the case of the Tephone Security System is not distinguished from the ordinary telephone call, there is a problem that the telephone call cannot be given priority although it is urgent. In addition, there is a problem that emergency information cannot be transmitted when the passenger is away from the automobile. Object of the Invention The object of the present invention is to display emergency information on a VDT device mounted on a vehicle when an occupant is present in the vehicle when receiving a radio wave that conveys the emergency information, and to carry the portable information carried by the occupant when there is no occupant in the vehicle. It is to provide an emergency notification system in which emergency information can be reliably transmitted by retransmitting emergency information to the unit. The emergency call system of the present invention is installed in an automobile having a VDT device, and includes an occupant presence / absence determining unit for determining the presence or absence of an occupant, a receiving unit for receiving an electric wave for transmitting emergency information, and a radio wave for transmitting an emergency information. When the VDT device is in operation when the transmitting means for re-transmitting and the radio wave for transmitting the emergency information are received, the emergency information is preferentially displayed, and the VDT device is not in operation and the occupant presence / absence determining means determines whether or not the occupant is present. If it is determined that the VDT device is present, the VDT device is activated and the emergency information is displayed.
An in-vehicle unit having an emergency control means for activating the transmission means and retransmitting a radio wave for transmitting emergency information when the DT device is not in operation and the occupant presence determination means determines that there is no occupant, and A portable unit that is portable to an occupant of an automobile, and that includes a receiving unit that receives a radio wave that transmits emergency information transmitted from the in-vehicle unit, and a reporting unit that outputs a reporting signal when receiving the signal. This is a feature of the configuration. Examples Hereinafter, the present invention will be described in more detail based on the examples shown in the drawings. Here, FIG. 1 is a block diagram showing in detail an on-vehicle unit of an emergency call system according to an embodiment of the present invention, and FIG.
The figure is a block diagram showing in detail the portable unit of the emergency call system. The present invention is not limited to the embodiments shown in the drawings. As shown in FIGS. 1 and 2, the emergency call system according to the present invention includes an on-vehicle unit 1 mounted on a vehicle C and a portable unit 21 carried by an occupant. The vehicle-mounted unit 1 includes three systems, an image display system 2, a personal wireless system 3, and an emergency control system 4. The image display system 2 displays the image information of any one of the TV tuner 5, the navigation system 6 and the inspection system 7 on the CRT.
It is selected by the controller 8 and displayed on the CRT display 9. The personal wireless system 3 includes a personal wireless device 10, a speaker 11 and a microphone 12. The emergency control system 4 includes an emergency controller 13 and a transmitter 15.
And have. The emergency controller 13 is always operating, outputs a receiver control signal to the personal radio device 10,
Even if the personal wireless device 10 is powered off, its tuner section is operated. Therefore, the personal wireless device 10 can always receive a radio wave that conveys emergency information. On the other hand, as shown in FIG. 2, when the transmitter 31 on the transmitting side H detects an abnormality by, for example, the fire sensor 32, the gas leak sensor 33, or the intrusion sensor 34, it transmits a radio wave by the transmitter 35 to convey the emergency information. It is something to send. When the personal wireless device 10 receives a radio wave that conveys emergency information, it outputs a reception signal to the emergency controller 13. Then, the emergency controller 13 determines from the received signal whether or not it is a notification to itself, and if it is a notification to itself, outputs a receiver control signal and causes the personal wireless device 10 to send back a recognition signal. Ignore if not a self-report. Upon receipt of the returned recognition signal, the sender H of the emergency information transmits a code indicating the content of the emergency information. It is preferable to transmit the content code of the emergency information after receiving the reply of the recognition signal as described above in order to prevent erroneous notification and leakage of privacy. When the content code of the emergency information is received by the personal wireless device 10 and input to the emergency controller 13, the emergency controller 13 checks the state of the ignition switch 14. Ignition switch 14 is "OH" or "ACC"
If so, it is determined that there is an occupant in the vehicle. Then, the emergency display pattern corresponding to the content code is C
A display control signal is output to the CRT controller 8 for display on the RT display 9. If another screen is being displayed when the display control signal is input, the CRT controller 8 interrupts the screen display and preferentially displays the emergency display pattern on the CRT.
Display on the display 9. If the screen display is not being performed when the display control signal is input, the CRT display 9 is activated to display the emergency display pattern on the screen. Further, the emergency display controller 13 causes the speaker 11 of the personal wireless system 3 to emit an emergency alarm sound in response to the receiver control signal. On the other hand, when the ignition switch 14 is "OFF", it is considered that there is no occupant in the vehicle, so an emergency display is not displayed to prevent unnecessary battery consumption, but the transmitter 15 is activated and directed to the mobile unit 21. To transmit radio waves that convey emergency information. As shown in FIG. 2, the portable unit 21 receives the radio wave from the vehicle-mounted unit 1 at the transmitter 22, and then the driver 2
The LCD display 24 and the buzzer 25 are driven by 3 to display emergency information and generate a warning sound. Therefore, the occupant of car C is CR when he is in the car.
The display of the T display 9 and the voice of the speaker 11 notify the emergency information, and the portable unit 21 notifies the emergency information when the user is away from the automobile. Another example is one in which the presence or absence of an occupant is determined by turning a seat switch on and off. Further, as another embodiment, there is one in which the emergency information which is not displayed because there is no occupant is stored and is displayed when the occupant is present. Yet another embodiment is one in which the personal radio 10 is not used and a receiver is separately provided.
