In the information communication device in the house, when the information is sent to the management center, the telephone line is congested when the management center is called by performing an automatic dial, and the waiting time (for several seconds) has elapsed from the management center. If there is no answer, the telephone line is opened once, and automatic dialing is performed again to repeat the automatic dialing until there is a response from the management center.

However, in the conventional in-home information communication apparatus, even when the other party (management center) transmits a busy tone by a telephone connection error of the telephone exchange, regardless of whether the line is in use or receiving a call signal, the number 10 If there is no waiting for a second, the following automatic dial is not performed, and there is an inadequacy that it is not possible to send emergency information such as emergency, emergency prevention, or emergency that requires urgently.

Therefore, in order to eliminate such inconsistencies, it is also considered to make the waiting time for waiting for a response from the management center shorter than the conventional time. There is a possibility that information in the house cannot be transmitted because it is not connected.

An object of the present invention is to provide an information communication apparatus which shortens the waiting time of an automatic dial before being connected to a management center.

The present invention transmits information to the management center via a telephone line when there is a response from the management center during a waiting time for waiting for a response from the management center when the management center is called by performing an automatic dial. And at the same time, if there is no response from the management center even after the waiting time has elapsed, the information communication apparatus which opens the telephone line once and repeats the automatic dial at least twice until there is a response from the management center. The technical means which shortened the waiting time of the 1st automatic dialing than the 2nd automatic dialing was employ | adopted.

In the present invention, when the management center is called by the first automatic dial, even when there is no response from the management center, the first waiting time is short, so that the time until the second automatic dial is reached is shortened.

Therefore, regardless of whether the other party (management center) is not using the line or receiving a call signal, even if the telephone exchange sends a busy tone due to a connection error of the telephone exchange, the second automatic dial is used. Urgent information such as emergency, crime prevention or first aid that is urgently transmitted is sent quickly.

In addition, even when the telephone switchboard has a long connection time for the telephone line, since the waiting time for the second automatic dial is as long as the conventional one, the second automatic dial enables transmission to the management center.

When the determination result of this step S1 is Yes, control of step S3 is performed.

When the determination result of step S1 is No, it is determined whether emergency information, such as a gas leak signal, a crime prevention abnormality signal, or an emergency medical signal, is read (step S2).

When the determination result of this step S2 is No, control of step S1 is performed.

When the determination result of the stainless S2 is Yes or when the determination result of the step S1 is Yes, it is judged whether or not the telephone 2 is in use. In other words, it is determined whether the call is in progress (step S3).

When the determination result of step S3 is Yes, control of step S1 is performed.

If the determination result in step S3 is No, it is determined whether or not an incoming call is being made (step S4). If the judgment result of step S4 is Yes, control of step S1 is performed.

When the determination result of step S4 is No, the telephone switch 2 and the telephone line network L are separated by the mode switching circuit 83, and the computer 4 and the telephone line network L are connected. That is, the telephone line is connected (step S5), and after the telephone line is connected, for example, it is judged whether it has passed for 3 seconds (step S6).

When the determination result of this step S6 is No, control of step S6 is performed.

When the determination result in step S6 is Yes, the telephone number of the computer C of the management center is automatically dialed to call the computer C of the management center (step S7).

Then, it is judged whether or not the information request signal (PB signal: 0 sign, for example) is received from the computer C of the management center (step S8).

If the determination result in step S8 is Yes, the information in the house is transmitted to the computer C of the management center based on the transmission protocol flow chart (step S9), and the retransmission request signal from the computer C of the management center ( PB signal: For example, it is determined whether or not a 0 code is received (step S10).

When the determination result in step S15 is Yes, it is determined whether or not the first waiting time (Tlset: for example, 15 seconds) has elapsed after starting the automatic dial (step S16).

When the determination result of this step S16 is No, control of step S8 is performed.

If the determination result in step S16 is Yes, then control of step S13 is performed.

If the determination result in step S15 is No, it is determined whether or not the second waiting time (T2set: for example, 45 seconds) has elapsed after starting the second automatic dial (step S17).

When the determination result of step S17 is No, control of step S8 is performed.

In addition, when the determination result of step S17 is Yes, control of step S13 is performed.

As described above, when the terminal device 1 of the information communication device A in the house calls the computer C of the management center by the first automatic dial, the first waiting time Tlset: Even after 15 seconds have elapsed, even if no information request signal (PB signal: 0 sign) is received from the computer C of the management center, the first waiting time (Tlset: e.g. 15 seconds) Because of the short time, the time to reach the second automatic dial is shortened.

For this reason, even when the telephone exchange sends a busy tone due to a connection error of the telephone exchange, etc., emergency information such as disaster prevention, crime prevention or first aid that require urgentness can be promptly transmitted by the second automatic dial.

In addition, even if the telephone switchboard has a long connection time for the telephone line, the second waiting time of the second automatic dial (T2set: 45 seconds, for example, is relatively long. Since (4) is more likely to be connected, emergency information can be transmitted by the second automatic dial.

In this embodiment, the response from the management center is awaited by the two types of waiting time of the first and second waiting time, but two or more types of waiting time may be provided as long as the waiting time of the first automatic dial is shorter. .

Moreover, you may make it possible to convert the length of a waiting time into arbitrary length. In addition, about the 3rd time and after, the same long waiting time as 2nd time may be provided or the combination of 1st time and 2nd time may be repeated.

In addition, 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 nursing center.

According to the present invention, even when there is no response from the management center during the first automatic dial, the time until the second automatic dial can be reached quickly.

Therefore, even if the management center is not busy or receiving a call signal, the following automatic dialing can be performed in a short time even when the telephone exchange sends a busy tone due to a connection error of the telephone exchange. Therefore, emergency information such as disaster prevention, crime prevention, or first aid requiring emergency can be transmitted quickly.

For example, even if the telephone exchange used has a long connection time for the telephone line, since the waiting time for the automatic dial is set relatively long after the second time, it is possible to determine the school rate connected to the management center by the automatic dial. As we can make high, information in house does not become impossible to transmit.
