It is a flowchart.

First, the data collection and transfer device 2 will be described with reference to FIGS. In FIG. 5, reference numeral 21 denotes a flow rate integrating unit that integrates and records gas usage, 22 denotes a flow rate excess determining unit that determines that the gas usage per unit time has reached a certain fixed value or more, and 23 denotes time. Is a clock section that generates a reading, 24 is a meter reading date recording section that records the meter reading date to which the integrated value recorded in the flow rate integrating section 21 is transferred, 25 is a remaining quantity data management section that manages the remaining quantity of gas, and 26 is an input. A data control unit 27 for controlling output data includes an interface (I /
O) and 28 are processors (CPU) that perform processing.

A flow pulse generated each time a unit volume of gas flows is input to the I / O 27-1 from a sensor (not shown). A signal is input to the I / O 27-2 when a gas leak is detected from a gas leak sensor (not shown).

The I / O 27-3 is connected to a telephone line, and the data recording device 1 of the center is connected via a telephone exchange (not shown).

The meter reading date recorded in the meter reading date recording unit 24, the flow rate over determination value recorded in the flow over determination unit 22, the report residual value recorded in the residual data management unit 25, and the like are stored in the data recording device of the center. 1.

When a change occurs in the customer information, the data collection / transfer device 2 sends an alarm notification or data transmission to the data recording device 1 instead of immediately transmitting the changed data. After the transfer, the changed data is transferred.

That is, data transfer from the data collection and transfer device 2 to the data recording device 1 is not performed frequently, but is shared with a telephone line. Since it is necessary to provide a complicated circuit for stopping the shared telephone bell, after the data transfer from the data collection and transfer device 2 is completed, the changed data is transferred to reduce the running cost. ing.

Next, the operation of the data collection and transfer device will be described with reference to FIG. In the process S21, the data control unit 26
Performs input data analysis. That is, I / O27
It is determined whether it is a flow rate pulse input from -1 or a gas leak signal input from the I / O 27-2. If it is a flow rate pulse, the process proceeds to step S22, and if it is a gas leak signal, the process proceeds to step S25.

In step S22, the data control unit 26 increments the integrated value recorded in the flow rate integrating unit 21 by one. Processing S
At 23, the flow rate overdetermination unit 22 determines whether or not the amount of gas used per unit time is equal to or greater than a certain value.
In the case of ES, the process proceeds to step S24, and in the case of NO, the process proceeds to step S26.

That is, in the process S23, the normal gas usage is constant, and if it is used much more than this value, it is considered that a fault has occurred in the gas piping system, and this fault occurrence is monitored. I have. In the process S24, the data control unit 26 dials the telephone number to which the data recording device 1 is connected to make the connection, and then notifies the flow rate over alarm. Further, after the notification is completed, it receives changed data from the data recording device 1 and rewrites the changed data.

In step S25, the data control unit 26 dials and connects the telephone number to which the data recording device 3 is connected, as in step S24, and then reports a gas leak alarm. Further, after the notification is completed, it receives changed data from the data recording device 1 and rewrites the changed data.

In step S26, the remaining data management unit 25
Determines whether or not to perform the remaining amount notification based on the remaining amount of the gas cylinder. If the determination result is YES, the process proceeds to step S27.
In the case of NO, the process moves to step S28. The determination as to whether or not to generate the remaining amount notification is made by, for example, determining whether the remaining amount is 30%, 20%, and 1%.
When it becomes 0%, the remaining amount 3, the remaining amount 2 and the remaining amount 1 data are output, respectively.

In step S27, the data control unit 26 transfers the remaining amount data output from the remaining amount data management unit 25 to the data recording device 1. Further, when the data transfer is completed, it receives the changed data from the data recording device 1 and rewrites the changed data. In the process S28, the data control unit 26 determines whether or not the time is recorded in the meter reading date recording unit 24 with reference to the current time from the clock unit 23. If the determination result is NO, the process proceeds to the process S21. Returning to the case of YES, the process proceeds to step S28.

In step S28, the data control unit 26 dials and connects the telephone number to which the data recording device 1 is connected, and then transfers the integrated value recorded in the flow rate integrating unit 21 to step S21. Move on. Further, when the data transfer is completed, it receives the changed data from the data recording device 1 and rewrites the changed data.
