Next, the operation of this embodiment will be described with reference to the drawings. 4 shows a transmission flowchart when gas leakage and gas leakage detection are impossible.

It is determined whether or not the gas leak sensor 22 outputs gas leak detection impossible information (0V) (step a 1).

It is determined whether or not 30 seconds have elapsed (Yes) when the gas leakage detection impossibility information (0 V) is detected (step a2). When 30 seconds have not elapsed (NO), repeat (Step a 2).

When 30 seconds have elapsed (Yes), it is again judged whether or not the gas leak sensor 22 outputs the gas leak detection impossible information to determine whether the gas leak sensor 22 is malfunctioning (step a 3). ). When no gas leak detection information is output (NO), the step a1 or less is repeated, and the output state of the gas leak sensor 22 is monitored again.

Therefore, in the present embodiment, when the power failure occurs in a plurality of houses (I, II, lII ...) at a time, or when the subscriber intentionally cuts the power, the gas leak detection information of the gas leak sensor 22 is managed. Since the gas leak detection information is transmitted at the time of periodic meter reading of the gas reading information of each house (I, II, III…) so as not to be transmitted to the center C at any time, the reception function of the management center C is paralyzed. Work disappears.

It is determined whether or not the gas leak signal 12V is input from the gas leak sensor 22 (step S 1).

When the gas leakage signal 12V is not input (NO), it is determined whether or not the first gas disconnection signal is input (step S 2). When the gas leakage signal 12V, the first gas disconnection signal, or the second gas disconnection signal is not input (NO), it is determined whether the timer time is the transmission timing of the gas meter reading information and the gas leak detection impossibility information as described above.

When the line use detection circuit 61 outputs the call mode (Yes), step S5 is repeated.

When the line use detection circuit 61 does not detect a call mode (NO), it is determined whether the ring tone detection circuit 62 detects an incoming call to determine whether an incoming call is being made from a telephone outside the house (I). Determine whether or not (step S 6).

Step S5 is repeated when the ring tone detection circuit 62 detects an incoming call (Yes).

When the ring tone detection circuit 62 does not detect an incoming call signal (NO), it is output to the circuit switching relay 65 to turn on the switch 66a, turn off the switch 66b, and turn off the telephone line network L and the dial. The signal generator circuit 64 is connected to the DC circuit 66 (step S7).

The dial signal generation circuit 64 generates a telephone number of the management center C stored in the CPU 5 in advance, and presents an automatic dial (step S8).

The management center C determines whether or not the incoming call is being started by the automatic dial of the terminal device 2 (step S 9). At the call arrival date (Yes), it is determined from the management center C whether or not the center signal detection circuit 63 has detected 0 information, which is an information request code (step S 10).

When the center signal detection circuit 63 detects a zero code (Yes), an information transmission code is generated from the dial signal generation circuit 64, so that the gas is periodically read information, gas leakage detection information, and first gas disconnection information. Transmission information such as second gas disconnection information or gas leakage information is transmitted to the management center C (step S 11).

Next, it is judged whether or not the transmission information by the transmission code has been transmitted to the management center C three times (step S 12). This enables retransmission even if there is a mistake in the transmission information.

When the transmission information is not transmitted three times (NO), after transmitting the transmission information by the transmission code to the management center C, the zero signal, which is an information retransmission request code, is transmitted from the management center C to the center signal detection circuit. It is determined whether or not 63 has detected (step S13). When the center signal detection circuit 63 detects a zero code (Yes), step 11 or less is repeated. When the transmission information is transmitted three times (Yes) or when the center signal detection circuit 63 does not detect the 0 sign (NO), it is output to the circuit switching relay 65 to turn the switch 66a off. The switch 66b is turned on to gradually advance the telephone line network L and the telephone T ₁ to open the DC circuit 66 (step S 14). The operation then ends.

In step S9, when the Santa signal detection circuit 63 does not detect the 0 sign (NO), it is determined whether or not 25 seconds have elapsed after the automatic dialing (step S15).

If 25 seconds have not elapsed (NO), repeat step S15. When 25 seconds have elapsed (Yes), it is output to the circuit switching relay 65, the switch 66a is turned off, the switch 66b is turned on, and the telephone line network L and the telephone T ₁ are connected to each other. (66) is opened (step S16).

Then, it is determined whether 5 seconds have elapsed (step S 17). When 5 seconds have not elapsed (NO), step S 17 is repeated. When 5 seconds have elapsed (Yes), it is determined whether or not the number of times of transmission has been three times after the automatic dialing (step S 18).

When the number of times is not three (NO), repeat step S5 or less again. Thereafter, it is determined whether 5 minutes have elapsed (step S19).

If 5 minutes have not elapsed (NO), repeat step S 19. When 5 minutes have elapsed (Yes), it is determined whether or not the number of times of transmission has been nine times after the automatic dialing (step S20). When the number of times of transmission is not nine (NO), the staff S 5 or less is repeated again. The operation ends when the number of times of transmission reaches 9 (Yes).

In step S10, when the center signal detection circuit 63 does not detect the 0 sign (NO), it is determined whether 25 seconds have elapsed since the automatic dialing (step S21).

Repeat step S21 when 25 seconds have not elapsed (NO). When 25 seconds have elapsed (Yes), it is output to the circuit switching relay 65, the switch 66a is turned off, the switch 66b is turned on, and the telephone line network L and the telephone T ₁ are connected to each other so that the DC circuit ( 66) (step S22).

Thereafter, it is determined whether 5 seconds have elapsed (step S23). When 5 seconds have not elapsed (NO). Repeat step S23. When 5 seconds have elapsed (Yes), it is determined whether or not the automatic dial is performed twice (step S24). When the automatic dial is not executed twice (NO), steps S5 and below are repeated again. When the automatic dial is executed twice, the operation ends thereafter.
