[0017]
The operation of the present invention will be described based on the above configuration.
[0018]
First, when the central processing unit 1 is installed in the house, the central processing unit 1 and the base unit 3 can communicate wirelessly and can be connected to a communication device registered in advance via the base unit 3 by an external line. Therefore, it is possible to install the central processing unit 1 anywhere in the house as long as wireless communication is within reach.
[0019]
Describes operations related to emergency calls. The user operates the emergency call means 16 of the terminal device 2 when an intrusion occurs even when at home, or when the user's physical condition suddenly changes and the outside needs to be contacted. Similarly, the address code of the terminal and the status code of the occurrence of an emergency situation are transmitted to the central processing unit 1, and the corresponding voice message based on this is sent to the telephone registered in advance by the control unit 10 via the master unit 3. A voice message notifying that the emergency call button has been pressed is sent to the fixed telephones 5 and 7 or the mobile phone 6 outside the house corresponding to the number. The person to be contacted who has been notified by the telephone outside the house can subsequently transmit a predetermined tone signal from the telephone, and the voice communication means 9 can be operated by the transmission / reception unit 11 via the base unit 3. In the terminal 2 that has transmitted the unsteady signal, the voice communication means 19 is in a standby state by the terminal control unit 17, and when the call signal from the voice communication means 9 of the central processing unit 1 is received, the voice communication means of the terminal 2 19 operates. As a result, the voice of the user carrying the terminal device 2 can be monitored on the telephone outside the home through the voice input means 13, and the status of the user can be confirmed. If necessary, it is possible to make a call to the user by the voice of the contacted person from the voice output means 20 through the telephone.
[0020]
Further, when not contacting outside, but communicating with a housemate, the audio signal from the terminal unit is not transmitted to the external telephone depending on the setting, but the audio output means 13 of the central processing unit 1 is used. It is loud from. As a result, the central processing unit 1 can confirm the situation by the voice of the user carrying the terminal device 2. In this case, an audio signal is output from the audio input means 14 of the central processing unit 1 to the terminal device 2. As a result, a voice call can be made from the central processing unit 1 to the user carrying the terminal device 2.
[0021]
Next, the operation when the terminal 2 is carried away from the central processing unit will be described. A response request signal is transmitted from the data communication means 8 to the terminal device 2 every minute under the control of the central processing unit 1 by the control unit 10. In this embodiment, the response request signal is transmitted every minute, but the setting unit 12 can set the time every hour. The terminal 2 transmits a response signal to the response request signal from the central processing unit 1 from the data communication means 18 to the central processing unit 1. When the user is within the reception range of the response request signal from the central processing unit 1, the above operation is repeated. However, if the user is kidnapped or goes out without permission and falls outside the reception range of the response request signal, the central processing unit 1 cannot receive a response signal from the terminal device 2 in response to the response request signal. The alarm is issued from the alarm generating means 15 for 20 seconds. In this embodiment, the alarm issuing time is 20 seconds, but the setting unit 12 can set the time every hour. Then, the address code of the terminal unit and the status code of the occurrence of an emergency situation are transmitted to the central processing unit 1, and based on this, the corresponding voice message is associated with the telephone number registered in advance via the master unit 3 by the control unit 10 A voice message notifying that an emergency has occurred is reported to the fixed telephones 5 and 7 or the mobile phone 6 outside the house. Next, since the terminal device 2 cannot receive the response request signal from the central processing unit 1, it is controlled by the terminal control unit 17 and an alarm is issued from the alarm generation means 22 for 20 seconds. In this embodiment, the alarm issuing time is 20 seconds, but the alarm issuing time of the terminal device 2 can be set every hour by the setting unit 12 of the central processing unit 1. In addition, since the central processing unit transmits the response request signal even after the terminal device 2 is once out of the reception range of the response request signal, the terminal device 2 is out of the reception range and within the reception range. The terminal device 2 is controlled by the terminal control unit 17, and the emergency call means 16 is automatically operated to execute the operation described in the explanation regarding the emergency call.
[0022]
As described above, when the user carrying the emergency call button in this embodiment falls into an emergency due to kidnapping or the like, an alarm is issued from the central processing unit or a voice message is sent to the communication device. As soon as possible, it will be possible to inform those who are at home or outside.
[0023]
In addition, when the terminal unit is within the reception range from the reception range of the response request signal of the central processing unit, a signal indicating that the terminal unit is in an unsteady state from the terminal unit to automatically operate the emergency call means. Is connected to a pre-registered communication device, and a non-stationary situation occurs by providing a control means for performing voice communication between the communication device and the terminal device that transmitted the unsteady state. Since it is possible to make a voice call from a communication device outside the home to the terminal that has been made, it is possible to give a sense of security to the emergency caller.
[0024]
Moreover, although the emergency call means of the present embodiment is configured by a push button switch, it may use another mechanical contact mechanism such as a type in which the contact is closed by grasping, or a blood pressure monitor, a pulse meter, etc. A similar effect can be obtained even when a sudden change in state is transmitted as an unsteady state occurrence in conjunction with a sensor that measures a physiological index.
[0025]
In the present embodiment, the terminal is an emergency call button, but the terminal may be attached to the car. In this case, there is no emergency call means or call function, and it is only necessary to have an alarm function for the central processing unit and the terminal unit and a function for reporting to an external telephone. With the above configuration, the central processing unit issues an alarm when the response signal from the terminal for the response request signal cannot be received for a predetermined time or longer. The terminal also issues an alarm when a response request signal cannot be received for a predetermined time or longer. By the above operation, it is possible to detect that the car has been stolen earlier, and it is possible to threaten by issuing an alarm from the terminal. In addition, it is good also as a structure which confirms the position of a vehicle, when it is stolen by providing a GPS receiving function in a terminal device.
[0026]
In this embodiment, wireless is used as a communication medium between the terminal and the central processing unit. However, any communication medium such as wired communication using a dedicated line, power line carrier communication, infrared communication, and optical fiber communication is used. Has the same effect.
[0027]
【The invention's effect】
As described above, according to the present invention, even when an emergency situation occurs due to a kidnapping or the like, it is promptly possible that an emergency situation has occurred due to an alarm issued from the central processing unit or a voice message to the communication device. It becomes possible to inform. In addition, since the alarm is issued from the terminal device 2, it is possible to inform the person around the terminal device that an emergency has occurred.
