Functions performed by the CPU31 according to a predetermined program include a gas meter reading function, a gas remaining amount management function, a gas shutoff logic function, a gas leak sensor monitoring function, a battery voltage detection function,
There are clock and calendar functions, setting functions, test functions, and transmission control functions. The outline of each function will be described below.

[Gas meter reading function]

The pulse output from the LP gas meter 3d at a constant flow rate is received by the input port I ₄ via the meter meter I / F 37 and integrated, and the integrated value is stored in the RAM 31b. The integrated value, that is, the meter reading value is represented by the number of pulses of 000000 to 999999, for example.

The above integrated value (meter reading value) is automatically notified to the information center 1. There are two ways to make a report.

One is a regular notification that has been conventionally performed, and the integrated value is periodically transmitted to the information center 1 at a date (reporting cycle) and a time (reporting time) set in the initial setting.

The other one is to transmit the latest integrated value as a meter reading value to the information center 1 at a predetermined notification time on a predetermined set day every month.

[Gas remaining amount management function]

Pulses input from the LP gas meter 3d at constant flow rates are integrated to calculate the remaining amount of LP gas in the cylinder. When the remaining amount of LP gas reaches the two remaining amount warning values set by the initial setting, the information center 1 is notified. The remaining amount of LP gas is
When the cylinder replacement switch 3f is turned on or when the remaining amount becomes 0, it is reset to the set cylinder capacity set by the initial setting.

When the cylinder exchange switch 3f is turned on, a cylinder exchange notification is sent to the information center 1, and at the same time, the confirmation LED 3g (built into the switch 3f) is turned on.

[Gas shutoff logic function]

The gas consumption is monitored by a pulse at a constant flow rate from the LP gas meter 3d, and a calculation is performed every unit time to determine an abnormality in the flow rate. When it is determined that there is an abnormality, a shutoff signal is output to the shutoff valve in the LP gas meter 3d via the controller 3e, and the information center 1 is notified of that fact.

In order to determine the above-mentioned abnormality, the maximum total flow rate is set by the initial setting, and when the gas exceeds the set maximum total flow rate, it is determined that there is an erroneous opening of the gas plug or a rubber tube is removed. The above-mentioned abnormality determination is performed when five pulses from the LP gas meter 3d are successively generated at intervals shorter than the pulse interval calculated from the set maximum total flow rate. Further, even when the maximum flow rate is exceeded, a gas shutoff signal is output to the shutoff valve via the controller 3e and the information center 1 is notified of that fact.

[Gas leak sensor monitoring function]

The voltage signal (0,6,12V) generated by the gas leak sensor 3c is monitored. When the input from the gas leak sensor 3c becomes more than 9 ± 0.5V, it is checked for 45 seconds and 9 ± 0.5V before 45 seconds.
When it becomes less than the value, it returns to the state of monitoring the input from the sensor again. When the state of 9 ± 0.5 V or more continues for 45 seconds or more, it is determined that there is a gas leak and a gas cutoff signal is output via the controller 3e to notify the information center 1 of the gas leak.

When the input voltage is less than 2 ± 0.5V, it is checked for 10 seconds, and if the state of less than 2 ± 0.5V continues for 10 seconds or more, the gas leak sensor 3c cannot operate (disconnection, disconnection of outlet, etc.)
Then, the information center 1 is notified of the abnormality of the gas leak sensor 3c. However, when the power failure detection signal is input from the controller 3e, the abnormality notification regarding the gas leak sensor 3c is not performed.

[Battery voltage detection function]

When the battery detection circuit 38 detects that the voltage of the built-in lithium battery 39 has dropped, it informs the information center 1 of the battery voltage drop. This notification occurs at a voltage about one month before it becomes inoperable.

[Clock and calendar function]

A clock is used for the transmission time of the scheduled notification, and a clock and a calendar are used for the transmission time and the transmission date of the automatic meter reading notification. Leap year corrections are done automatically.

Time data consists of hours and minutes (24 hours), and date data consists of year, month and day. The time data and the date data are set by the initial setting, and then set and corrected for each notification.

[Setting function]

Necessary setting data is set in a predetermined area in the RAM 31b by initial setting. The setting data is the information center 1 at the time of reporting
It can be sequentially updated by the transmitted setting data.
The following is set as the setting data.

1. User ID (user code number) 2. Telephone number to report to (up to 11 digits) 3. Dial method (dial pulse / push button) 4. Report time (time for regular report and automatic meter reading report: hours and minutes) 5. Report Cycle (Regular notification cycle: day [00 to 99]) 6. Notification date (automatic meter reading notification day: day [00 to 28]) 7. Gas meter reading value (meter reading 6 digits) 8. Maximum total flow rate (3 Digit [pulse / time]) 9. Set cylinder capacity (set cylinder capacity 6 digits [pulse number]) 10. Warning remaining point 1 (first warning point [pulse number]) 11. Warning remaining point 2 (first 2 Warning points [number of pulses]) 12. Current time (current time: hour and minute) 13. Current date (current year, month, day: year) If you set 00 as the notification cycle, the scheduled notification function will Not performed. If 00 is set as the notification date, automatic meter reading notification will not work.

[Test function]

It is possible to perform a function test with the information center 1 via the telephone line 4. When the data setting switch 42 is on and an abnormal signal is input, the line test information is transmitted to the information center 1. Other than the line test information, the current status is shown and transmitted.

[Transmission control function]

When sending information to the information center 1, the subscriber telephone set 3b
It is checked whether or not is being used or an incoming call is being made, and waits until the telephone line 4 becomes empty.

If the telephone line 4 is empty, the telephone number is automatically dialed according to the preset telephone number of the report destination.

When the information center 1 is busy, has an incorrect connection or does not receive a response from the information center 1, or when the transmission is not normally completed, the telephone line 4 is temporarily released and redialed after 50 seconds, for example. For example, if the information cannot be transmitted even by dialing a total of three times, the telephone is redialed after five minutes, for example. If the information cannot be transmitted even by three times of dialing at regular intervals in this redialing, the redialing is performed again, for example, after 5 minutes.

In the above configuration, after the apparatus is installed, the information center 1 is connected via a telephone line, and the operation of setting necessary information from the information center 1 in a predetermined area in the RAM 31b by initial setting is shown in the flowchart of FIG. Will be described in detail. In the flowchart of FIG. 5, two flowcharts A and B are executed in parallel by the time slice method, and both flowcharts are started by turning on the power.

After the installation of the device, the operator calls the information center 1 from the telephone 3b of the terminal to connect the information center 1 to the device through the telephone line when performing the initial setting. afterwards,
The operators of the information center 1 side and the device side mutually confirm and turn on the data setting switch 42, but since the data setting switch 42 is off until this point and the initial setting has not been performed yet, step S1A of the flowchart A And S2A
Both are NO and this step is repeated. And
When the data setting switch 42 is turned on, the determination in step S1A becomes YES, and the process proceeds to step S3A. In step S3A, it is determined whether or not the line is connected to the information center 1 based on the state of the input port I _7. However, in the above-mentioned state, the line is connected to the information center 1. Therefore, this step S3A
The determination is YES, and the process proceeds to step S4A.

In step S4A, a switch-on signal is output to the output port O ₃ , and the line is switched from the telephone 3b to the device side. Then, it progresses to step S5A and it is determined here whether it was connected with the information center 1. This determination is made by the response signal from the information center 1. When the determination in step S5A is NO, it is determined in step S6A whether 40 seconds have elapsed, 4
The determination in step S5A is repeated for 0 seconds. If connection to the information center 1 is not established even after 40 seconds have passed, step
When it is connected to the information center 1 40 seconds before, the process proceeds to step S7A.

In step S7A, the initial setting information is received from the information center 1, stored in a predetermined area in the RAM 31b, and in the subsequent step S8A, the information center receives a response indicating that the information is normally received. Then, the process proceeds to step S9A, and it is determined whether or not the information received here is the last information by whether or not the information received from the information center 1 has an end code, and until the determination becomes YES, step S7A And S8A
Repeat.

When the determination in step S9A becomes YES, the process proceeds to step S10A, in which the switch-on signal of output port O ₃ is eliminated, the line is switched from the device to the telephone 3b side, and the information center 1 side and the device side operator Make a call. After execution of step S10A, the process returns to step S1A. At this time, however, the state of the data setting switch 42 does not normally change from OFF to ON, so the determination in step S1A becomes NO, and the process proceeds to step S2A. The determination in step S2A is also YES because the initialization has already been performed, and the process proceeds to step S11A.

In step S11A, it is determined whether the gas flow rate pulse is generated in the LP gas meter 3d according to the state of the input port I ₄ . When the determination in step S11A is YES, in the subsequent step S12A, the past meter reading value (first 000000) stored in the predetermined area of the RAM 31b is incremented by 1 and replaced with the previous one in the predetermined area of the RAM 31b. To store.
If the determination is NO, skip step S12A and skip step S1.
Continue to 3A.

In step S13A, the notification date information set in the predetermined area of the RAM 31b by the above initialization is compared with the current date data read from the clock and calendar 33 to determine whether it is the notification date. If the determination is YES, the process proceeds to step S14A, where the notification time information set in a predetermined area of RAM 31b is compared with the current time data read from the clock and calendar 33 to determine whether it is the notification time. To determine. When the determination in step S13A is NO, the process returns to step S1A.

If the determination in step S14A is YES, the process proceeds to step S15A, where a flag for flag generation is set and the process returns to step S1. If the determination is NO, skip step S15A and return to step S1A.

On the other hand, in the flowchart B, it is determined in the first step S1B after the power is turned on whether or not the report factor generation flag is set. This step S1B is repeated until the determination becomes YES. If the determination in step S1B is YES, the process proceeds to step S2B, where it is checked whether the telephone line is empty or not depending on the states of the input ports I ₆ and I ₇ . Step S2B
Is repeated until the determination becomes YES. If the determination in step S2B is YES, the process proceeds to step S3B, where signals are output to output ports O ₃ and O ₄ to perform line capturing operation, and dial signals are output from input / output port IO to perform dialing operation. I do.

After that, the process proceeds to step S4B, and it is determined whether or not the connection with the information center 1 is made based on the response signal from the information center 1 input to the input / output port IO. This step S4
When the determination of B is NO, the process proceeds to step S5B, where it is determined whether 40 seconds have elapsed. When this determination is NO, the process returns to step S4B, and steps S4B and S5B are repeated until the determination of step S5B becomes YES, and when the determination of step S5B becomes YES, the process proceeds to step S8B.

If the determination in step S4B is YES, then step S6B
Then, the meter reading value and other information are transmitted from the input / output port IO to the information center 1 by a predetermined format. After that, the process proceeds to step S7B, where the response signal from the information center 1 is received and the report factor occurrence flag is set to 0.
To Then, proceed to step S8B, where the output port O
_After the output signals of ₃ and O ₄ are lost and the line is restored, the process returns to step S1B.

If the determination in step S4B is NO, steps S5B and S8
In the case of returning to step S1B via B, since the reporting factor occurrence flag is not 0, line capture and dialing will be performed again.

As is apparent from the processing operation of the CPU 31 described according to the flowchart of FIG. 5, the CPU 31 automatically dials the callee's telephone number written in the RAM 31b as a storage unit according to the occurrence of the reporter's factor, It functions as a notification means 31-1 which confirms the connection with the notification destination in response to the reception of a predetermined response signal from the device and then transmits the content of the notification. Further, the CPU 31 outputs a switching control signal to the switch circuit 47 and the relay circuit 52 in response to the detection by the TEL detection circuit 41 that the subscriber's telephone 3b is not using the telephone line 4 when the report factor is generated. When the setting switch 42 is manually operated, a switching control signal is sent to the switch circuit 47 and the relay circuit 52 in response to the detection by the TEL detection circuit 41 that the subscriber telephone 3b is using the telephone line 4. Functions as the switching control means 31-2 which outputs And CPU31
The switching control means 31-2 includes a switch circuit 47 and a relay circuit 52.
