As described above, when the terminal device 1 of the in-home information communication device A calls the computer C of the management center by the first automatic dialing, the first waiting time (T1set: 15 seconds, for example) elapses. Even if the information request signal (PB signal: 0 code, for example) is not received from the computer C of the management center, the first waiting time (T
Since 1 set is short (for example, 15 seconds), the time until the second automatic dial is reached is shortened.

Therefore, even if the telephone exchange emits a busy tone due to a connection error of the telephone exchange or the like, it is possible to promptly send emergency information such as emergency disaster prevention, crime prevention, or emergency by the second automatic dialing. it can. Further, even when the telephone exchange has a long connection time of the telephone line, the second standby time (T2set: 45 seconds, for example) of the second automatic dial is relatively long. Since there is a high possibility that the user will be connected, emergency information can be sent by the second automatic dialing.

(Modification) In the present embodiment, the response from the management center is waited for by the two kinds of waiting times of the first and second waiting times, but the waiting time at the first automatic dialing is the shortest. For example, two or more types of waiting time may be provided. Further, the length of the waiting time may be switched to an arbitrary length. For the third time and thereafter, a long waiting time similar to the second time may be provided, or the combination of the first time and the second time may be repeated. Furthermore, the present invention may be used for a medical information communication device that transmits emergency information such as emergency in a hospital room to a nurse center.

[0021]

According to the present invention, even when there is no response from the management center at the time of the first automatic dialing, the time until the second automatic dialing is reached can be shortened. Therefore, even if the control center is not using the line or receiving a ringing signal, the next automatic dialing will be performed in a short time even if the telephone exchange makes a busy tone due to a connection error etc. of the telephone exchange. Therefore, it is possible to promptly transmit emergency information such as emergency disaster prevention, crime prevention, or emergency. Also, for example, even if the telephone exchange used has a long telephone line connection time, the standby time for the second and subsequent automatic dials is set to be relatively long, so the probability of being connected to the management center by automatic dialing is high. Since it can be increased, the in-home information will not be unable to be transmitted.
