Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for automatically and remotely reading the gas consumption of a gas cylinder, and for example, to an automatic remote reading system for propane gas using wired broadcast telephone equipment.

The conventional automatic remote meter reading system was designed to save labor in meter reading and document processing by centrally reading the cumulative amount of gas used by each household, such as propane gas, at a center. With this method, it is not possible to easily know the amount of gas consumed in each household's gas cylinders within the center, making it difficult to replace gas cylinders efficiently, and it is necessary to install multiple gas cylinders to prevent gas from running out. It was necessary.

The present invention eliminates the above-mentioned drawbacks of the conventional technology, and its purpose is to make it possible to easily and centrally read the gas consumption of gas cylinders in each household at a center, thereby saving labor in delivery operations. There is a particular thing.

A feature of the present invention to achieve this objective is that the cumulative amount of gas used by gas users is transmitted to the center via a communication line at the time of meter reading, so that the cumulative amount of gas used is displayed on the meter reading device of the center. In the gas automatic remote meter reading system,
This automatic remote gas meter reading system is characterized in that the display of cumulative gas consumption can be reset by an operation on the gas user's side.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a system diagram showing an embodiment of a propane gas automatic remote meter reading system using wired broadcasting telephone equipment according to the present invention, in which 1 is a switch, 2 is a telephone speaker, 3 is a terminal device,
4 is a meter equipped with an oscillator to measure gas consumption, and 5 is a reset switch. Items 1 to 5 above are installed in each home.

Further, in FIG. 1, numeral 6 indicates a main distribution board in the telephone exchange, 7 indicates a switchboard in the telephone exchange, and 8 indicates a meter reading device in the meter reading center 12.

Here, when the terminal device 3 installed in each home is called from the meter reading device 8 in the meter reading center 12 via the switch 1, the terminal device 3 transfers the data accumulated in advance from the meter 4 to the meter reading device 3. Perform the operation to send to.

FIG. 2 shows in detail the terminal device 3, meter 4, and reset switch 5 shown in FIG. 1, and 9 is an interface;
Reference numeral 10 indicates a memory counter, and reference numeral 11 indicates a code transmitter. The terminal device 3 is installed inside the residence, and the meter 4 and reset switch 5 are installed outside the residence.

When using propane gas, the unit consumption is meter 4
is measured and input to the memory counter 10 via the interface 9, where it is accumulated.

This memory counter 10 adds up and accumulates the unit usage amount, and when a meter reading is performed, the above-mentioned cumulative usage amount is sent as data to the meter reading device 8 in the center via the code transmitter 11.

Now, if the reset switch 5 is operated manually or automatically every time the gas cylinder is replaced, the memory counter 10 is reset.
The cumulative usage amount indicated by 0 always represents the gas consumption amount of the gas cylinder, and when a meter is read, the gas consumption amount of each household's propane gas cylinder will be displayed on the meter reading device in the center.

As explained above, according to the gas automatic remote meter reading method of the present invention, it is possible to accumulate the gas consumption of gas cylinders in the memory counter of the terminal device as necessary.
In this case, the gas consumption amount of gas cylinders in each household can be easily and centrally read at the center, which has the advantage of reducing the number of gas cylinders installed and saving labor in delivery operations such as replacement.
