It is judged whether or not the transmission timing timer time of the gas meter reading data in the automatic dial to the management center 3 set for each house (step 101), and when it is not the transmission timing timer time (NO), the gas leak sensor S1. It is determined whether or not the gas leakage signal 12V from () is input (step 102). When the gas leakage signal 12V is not input (NO), the step 101 is repeated. When the transmission timing timer time (Yes) or when the gas leakage signal is input (Yes), the code number (for example ^* 05) of the management center 3 is read (step 103).

Next, to determine whether or not the telephone T is in use, it is judged whether or not the line use detection circuit 23a detects a call mode (step 104). When the line use detection circuit 23a detects the call mode (Yes), the step 104 is repeated.

When the line use detection circuit 23a does not detect the call mode (NO), it is determined whether the ring tone detection circuit 23b detects an incoming call to determine whether an incoming call from a telephone road outside the house is in progress. It is determined whether or not (step 105). When the ring tone detection circuit 23b detects an incoming call output (Yes), the step 104 is repeated.

When the ring tone detection circuit 23b does not detect an incoming call (NO), it is output to the line switching relay 23e to turn on the contact 23g, turn off the contact 23b, and turn off the telephone line (L). And the PB signal generation circuit 23d are connected to connect the DC circuit 23f (step 106).

It is determined whether 3 seconds have elapsed since the connection of the DC circuit 23f (step 107). When 3 seconds have not elapsed since the connection of the DC circuit 23f (NO), the step 107 is repeated. When 3 seconds have elapsed since the connection of the DC circuit 23f (Yes), the management center 3 is called at the time of data transmission to the management center 3 (the gas company G at the time of data transmission to the gas company G). The auto dial is started (step 108).

When the PB signal detection circuit 23j detects the # code (Yes), it transmits transmission data such as gas reading data or gas leakage data to the management center 3 (or gas company G) by the transmission code. Transmit (step l10).

In the step 109, when the PB signal detection circuit 23j does not detect the # sign (NO), it is determined whether or not the number of times of transmission is three times after the automatic dialing (step 11l). When the number of times of transmission is not three (NO), it outputs to the line switching relay 23e, turns off the contact 23g, turns on the contact 23h, and turns on the public line L of the telephone and the main telephone T. ), The DC circuit 23f is turned off (step 112). Thereafter, it is determined whether 5 seconds have elapsed (step 113). When 5 seconds have not elapsed (NO), the staff 113 is repeated. When 5 seconds have elapsed (Yes), the staff 104 or less is repeated again.

When the number of times of transmission is three (Yes), it is then judged whether or not 15 seconds have elapsed (step 114). When no 15 seconds have elapsed (NO), the process proceeds to the staff 112. When 15 seconds have elapsed (Yes), it is output to the line switching relay 23e, the contact 23g is turned off, the contact 23h is turned on, and the public line L of the telephone and the main telephone T are connected. The DC circuit 23f is turned off (step 115).

Here, it is determined whether or not the second automatic dial is performed (step 116). When the second automatic dial is not performed (NO), it is determined whether 5 minutes have elapsed (step l17). When 5 minutes have passed (Yes), the staff 104 or less is repeated again.

When the second autodial is performed (Yes), it is determined whether or not the third autodial is performed (step 118).

When the third automatic dial is not performed (NO), it is determined whether 5 minutes have elapsed (step 119). When 5 minutes have not passed (NO), the staff 119 is repeated. When 5 minutes have passed (Yes), the staff 104 or less is repeated again.

When the third automatic dial is performed (Yes), it is determined whether or not safety information such as gas leakage data is transmitted (step 120). The operation ends when the safety information is not transmitted (NO). At the time of transmission of the safety information (Yes), it is determined whether or not the automatic dialing to the gas company G is finished (step 121). When the automatic dialing to the gas company G is finished (Yes), the operation ends.

When the automatic dialing to the gas company G is not finished (NO), the code number (for example, ^* 06) of the gas company G is read (step 122). Thereafter, the operation of the staff 104 or less is repeated again with the staff 104 or less as an automatic dial to the gas company G. When the automatic dialing to the gas company G is finished (Yes), the operation ends.

The information notification device transmits various data such as safety information and meter reading information to the management center so far, and then transmits various data from the management center to predetermined organizations such as a gas company, a fire station, and a police station. Although the number of people responded according to the above data, at the time of transmission of safety information, the number of people in the management center missed the data, and there was a case in which contact to a predetermined institution was delayed.

Therefore, as described above, the present embodiment first transmits safety information such as gas leakage generated in the house to the management sensor 3 together with the gas reading information, and then to the gas company G. For example, the management sensor 3 can contact the gas company G without personnel, and the gas company G can operate the gas shutoff valve according to the gas leakage information to supply gas to the house. Since it is possible to block, the accident of gas explosion or fire due to the delay of contact to the gas company G can be prevented due to the missing data of the personnel of the management center 3.

The staff 110 transmits the transmission data by the transmission code to the management center 3 and then determines whether or not the data retransmission request (#) code is received from the management center 3. It is determined whether the detection circuit 23j has detected the # code (step 123). When the PB signal detection circuit 23j detects the # code (Yes), the processing proceeds to the step 111.

When the PB signal detection circuit 23j does not detect the # sign (NO), it is then determined whether 3 seconds have elapsed (step 124). When 3 seconds have not elapsed (NO), steps 123 and below are repeated. When 3 seconds have elapsed (Yes), it outputs to the line switching relay 23e, opens the contact 23g, closes the contact 23h, connects the telephone's public line L and the telephone T, and The circuit 23f is opened (step 125). Then proceed to staff 120.
