The automatic meter reading of the gas counts the number of pulses output by the gas meter reading meter 21 to calculate the gas consumption in the gas cylinder, and integrates the gas consumption calculated by the gas usage calculating processor 51a. The date and time of the periodic meter reading (for example, 10:15 am on the 25th of every month) and the date and time counted by the timer 51d are compared with the accumulated memory processor 51b that stores the value and the periodic meter reading timer time memory 51c.

The detection of the replacement timing of the gas cylinder resets to the initial value by the rising trigger when the reset switch 23 is turned on, and also stores the trip accumulation memory 52a and the trip which store the accumulated value of the gas consumption after the reset. The accumulated value stored in the integrated storage processor 5a is compared with the integrated value corresponding to 70% of the gas cylinder gas stored in the first gas cut capacity setting unit 52b, and stored in the trip integrated storage processor 52a.

Send to center C.

Next, the operation of this embodiment will be described based on the flow chart of the gas automatic inspection of FIG. 5, the detection of the replacement time of the gas cylinder, and the transmission control of gas leakage. It is determined whether or not the gas leakage signal 12V is input from the gas leakage sensor 22 (step S1). When the gas leakage signal 12V is not inputted (NO), it is determined whether the first gas disconnection signal or the second gas disconnection signal is input (step S2). When the gas leakage signal 12V, the first gas disconnection signal or the second gas disconnection signal are not inputted (NO), the automatic dial to the management center C set for each house (I, II, III…) On-time tire time transmission of the gas reading information, i.e., the date and time counted by the timer 51d, reaches the date and time stored in the on-time reading timer time storing unit 51c or the periodic reading timer time storing unit 51f (for example, 25 days). 10:15 am or 11:00 am Wednesday) (step S3). When the transmission time is not the timer time (NO), the step S2 or less is repeated. When the timer is at the time of transmission timer (Yes), or when the gas leakage signal (12V) is inputting the first gas disconnection signal or the second gas disconnection signal (Yes), the telephone number of the management center (C) is read (step S4). ).

Next, to determine whether or not the telephone T ₁ is in use, it is judged whether or not the line use detection circuit 61 detects a call mode (step S5). When the line use detection circuit 61 detects the call mode (Yes), the step S5 is repeated. Whether or not the ring tone detection circuit 62 detects an incoming call when the line usage detection circuit 61 is not detecting a call mode (NO) to determine whether an incoming call is being made from a telephone outside the house (I). It judges (step S6). 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 (NO), it is output to the circuit switching relay 65 to turn on the switch 66a and to turn off the switch 66b to generate a telephone line network L and a dial signal. The circuit 64 is connected to connect the DC circuit 66 (step S7). The telephone number of the management center C previously stored in the CPU 5 is generated from the dial signal generation circuit 64 to start the automatic dial (step S8). The management center C determines whether an incoming call is being made by an automatic dial of the terminal device 2 (step S9). At the incoming call outing day (Yes), the O center, which is an information request code, is transferred from the management center C. It is judged whether the signal detection circuit 63 has detected (step S10). When the center signal detection circuit 63 detects a zero code (Yes), it generates an information transmission code from the dial signal generation circuit 64, and thus the periodic meter reading information, the first gas disconnection information, and the second gas disconnection information of the gas. Or transmission information such as gas leak information to the management center C (step S11).

Next, it is judged whether or not the transmission information by the transmission code has been transmitted to the management center 3 three times (step S12). This enables retransmission even when 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 0 code, which is an information request request code, is transmitted from the management center (C) to the center signal detection circuit ( It is determined whether or not 63) has been detected (step S13). When the center signal detection circuit 63 detects a zero code (Yes), the step S11 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 code (NO), it is output to the circuit switching relay 65 to turn the switch 66a off, The 66b is turned on to connect the telephone line network L and the telephone T ₁ to open the DC circuit 66 (step S14). The operation then ends.

In step S9, when the center signal detection circuit 63 does not detect the 0 code (NO), it is determined whether or not 25 seconds have elapsed since the automatic dial is performed (step S15). When 25 seconds have not elapsed (NO), step S15 is repeated. 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) (step S16). Then, it is determined whether 5 seconds have elapsed (step S17). If 5 seconds have not elapsed (NO), repeat step S17. When 5 seconds have elapsed (Yes), it is determined whether or not the number of times of transmission after the automatic dial has been reached (step S18). If the number of times is not 3, repeat step S5 or less. Then, it is determined whether 5 minutes have elapsed (step S9). When 5 minutes have not elapsed (NO), step S19 is repeated. 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 no number of times is 9 (NO), repeat step S5 or less. The operation ends when the number of times of transmission is 9 (Yes). In step S10, it is determined whether or not 25 seconds have elapsed since the auto-dial is executed when the center signal detection circuit 63 does not detect the zero code (NO) (step S21). When 25 seconds have not elapsed (NO), step S21 is repeated. 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. ) Is opened (step S22). Then, it is determined whether 5 seconds have elapsed (step S23). Repeat step S23 when 5 seconds have passed (NO). 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), repeat step S5 or less again. When the autodial is running twice (Yes), the next operation ends. The terminal device 2 installed in the house I side periodically transmits the meter reading information of the gas to the management center C through the telephone line network L, and the meter reading information at a shorter interval than the regular meter reading time. Since both periodic meter readings are periodically transmitted to the management center 3 via (L), the management center C generates troubles such as transmission control of the terminal device 2 and error of meter reading information in a short period of time. can do.

In this embodiment, although a telephone line network is used for transmission, other communication lines or radios using a communication satellite may be used.

When a first aid button for a sick case is connected to the input part 4 of this embodiment, when a sickness box turns on the first aid button, a predetermined hospital can be notified. When the emergency button is connected to the input unit 4, the police station, the fire station, and the gas company can be notified when the suspicious person enters, fires, or leaks.
