Communication means.

The gas supply device of the first embodiment is constituted by the communication means 16 from the use side container 1.

Next, the operation of this embodiment will be described in detail with reference to the flowchart of FIG. Automatic switching regulator 5
Is that when the gas in the use side container 1 is consumed by the stove 3, the use side container pressure is equal to or lower than a certain pressure (in this embodiment, 1
kg / cm 2), and if the gas supplied from the use side container 1 alone cannot supply the required amount of consumption (S1), the gas automatically flows from the spare container 2 to cover both sides. The pressure of the use side container 1 is 0.5 kg /
It is consumed until it reaches about cm 2 (S2).
The container switching signal generator 6 outputs a container switching signal when the supply of gas from the spare container 2 starts (S3). If the pressure of the use side container 1 has not fallen below a certain pressure, the process of S4 is performed. Next, when replacing the use side container 1,

Also, S1
When it is detected in step 6 that the change is due to normal container replacement, the communication means 16 uses the telephone line via the network control means 17 to operate the normal switching lever 8 by container replacement to the gas supply company. Then, a normal process for notifying the user is performed (S18). The gas supply company clears the container replacement signal and the switching lever signal when the operation of the switching lever 8 is obtained by mischief due to container replacement or operation information of the switching lever 8 due to an incorrect work procedure other than the regular container replacement work. The message to be transmitted is sent to the communication unit 16, the communication unit 16 decodes the content of the message, and the container switching unit 7 and the switching lever unit 18 clear the container exchange signal and the switching lever signal, respectively (S19).

With the above configuration, the determination means 19 determines that the switching lever signal when there is no container switching signal is an operation of the switching lever 8 due to mischief or an operation of the switching lever 8 due to an erroneous operation procedure other than the normal container replacement operation. Thus, it is possible to determine whether the operation of the switching lever 8 is due to a regular container exchange or an abnormal operation such as mischief, and even if the abnormal operation of the switching lever 8 such as mischief is performed, the communication is performed. The means 16 sends information to the gas supply company that the abnormal operation of the switching lever 8 has been performed, and the operation of the abnormal switching lever 8 such as a mischief or the like between the use side container 1 and the spare container 2 immediately before the container switching. The gas consumption is continued as the spare container 2 is changed to the use container 1 to prevent the exhaustion of gas generated when the use container 1 having almost no remaining amount operates as the spare container 2. It can be, it is possible to supply a stable gas.

Further, according to the above configuration, when the judging means 19 judges that the operation of the switching lever 8 is abnormal, the warning means 20
Acts so as to issue a warning until the switching lever 8 returns to a normal state, and can prevent mischievous or erroneous container replacement work that can notify the operation of the switching lever 8 due to mischief or erroneous container replacement work.

Also, if the judging means 19 determines that the abnormal switching lever 8
When the operation is determined, the display means 21 acts to display the normal state of the switching lever 8 until the switching lever 8 returns to the normal state. It is possible to return to the relationship of the spare side container 2 and the work efficiency of the attendant can be improved.
