Description

[Detailed description of the invention] [Industrial application field]

TECHNICAL FIELD The present invention relates to a gas supply system used in gas piping by being connected to a lead-in pipe to each household.

[Prior art]

Generally, in the gas industry, when collecting gas charges from each household, the gas meter is read every two months.
Fees are charged according to the amount used, and the fees are automatically deducted through a financial institution or collected individually from each household. Then, an account and list is created for each household, and charges are calculated based on the meter readings, and the list is handed over to the corresponding financial institution for processing, or a bill collector visits each household to collect the charges. That's what I do.

[Problem to be solved by the invention]

In the gas meter reading process, the meter boxes are installed in different locations in each household, making it difficult to find them, and the numbers often being misread, which is troublesome to deal with. Computers are also used to calculate and collect tolls based on meter readings, but this eliminates the need for a large number of personnel, and at the same time, the input work into the computer is complex and takes a lot of time. This poses a major problem in that gas prices cannot be reduced because the costs involved are enormous.

[Means for Solving the Problems 1] As a specific means for solving the problems of the conventional example, the present invention connects a meter for detecting the gas flow rate and a shutoff valve to the gas pipe, and a display driven by the meter. , an opening/closing mechanism for opening and closing the shutoff valve, and a control section, the control section reading the memory contents of the magnetic card and setting and displaying the gas flow rate on the display section based on the contents, as well as setting and displaying the gas flow rate on the display section. The present invention aims to provide a gas supply system characterized in that the gas flow is made to flow in accordance with the gas flow rate, and the memory of the magnetic card is canceled, and at the same time, the meter or the display part is connected to the shutoff valve. The system is configured to sequentially measure and display the amount of gas used that circulates based on the opening, and to stop the opening operation via the opening/closing mechanism when the amount of gas used reaches a set amount, and also for each household. A magnetic card having a unique code and a predetermined amount or gas flow rate stored therein is distributed, and the magnetic card can be reproduced or reissued by a predetermined reproducing or reissuing device, and the magnetic card is controlled by the controller. By having the unit read the information, settings can be made so that the corresponding amount of gas can be distributed, thereby eliminating the need for meter reading, calculation, and fee collection. - and the amount is memorized, the gas usage status of each household can be easily grasped, and the costs incurred can be drastically reduced, making it possible to drastically reduce gas charges. [Example] Next, the gas supply system of the present invention will be explained in more detail with reference to an embodiment shown in the drawings. 1 is a gas pipe, and the usage amount is set in advance or arbitrarily set in the gas piping. The meter 2, which can be opened, and the shutoff valve 3, which is normally closed, are connected in an adjacent state. The meter 2 is provided with a display section 4 that measures and displays the gas flow rate or displays a set usage amount in advance,
When the numerical value on the display reaches a set value or when the set numerical value becomes O, the opening/closing mechanism 5 is operated by a predetermined signal or mechanical drive, and the shutoff valve 3 is brought into a non-operating state. The setting value on the display section 4 is set by the control section 6, which is a magnetic card reader or a performance mechanism. The shutoff valve 3 has, for example, a valve mechanism that operates in a normally closed state, and the opening/closing mechanism 5 is a valve stem 3 of the shutoff valve 3.
a to maintain the open state. The opening/closing mechanism 5, which maintains the open state, is driven by a control unit 6 consisting of a magnetic card reading or arithmetic mechanism to forcibly open the shutoff valve 3 and maintain that state. In any case, when receiving a signal or action from the display section 4 or the control section 6 driven by the meter 2, the opening/closing mechanism 5 operates to open/close the shutoff valve 3, and in particular, the usage amount is set at the set value. When this is reached, the maintenance of the open state of the shutoff valve 3 is interrupted and the shutoff valve 3 is brought into the closed state. The meter 2, the shutoff valve 3, the display section 4, the opening/closing mechanism 5, and the control section 6 can be compactly stored in, for example, - boxes 7, as shown in FIG. In this case, the box 7 is provided with a display window 8 corresponding to the display section 4, a magnetic card insertion slot 9, a setting button 10, and the like. Note that 11 is a pilot lamp that indicates the operating state. When a magnetic card is inserted into the insertion slot 9 of the box 7 having such a configuration, the content of the magnetic card is read by the control section 6 consisting of the reading or calculation mechanism and displayed on the display section 4.
By displaying this on the screen and pressing the set button 10, the switch 15 is operated and the normally closed shutoff valve 3 is opened, allowing gas to flow. At this time, the set button 10 is a kind of confirmation or drive start button, and by pressing it, the content stored on the magnetic card, for example, the gas flow rate corresponding to a predetermined amount of money, is displayed. , is stored in the control section 6 and displayed on the display section of the meter 2, and the contents (amount of money or gas flow rate) are erased from the magnetic card so that the magnetic card can be taken out. The display 2 is sequentially subtracted as the gas flows, and when the corresponding gas flow rate ends, the shutoff valve 3 is closed by a signal from the display unit 4 or the control unit 6, and the gas flow is stopped. If you do not need the button 10, insert the magnetic card into the insertion slot 9.
The corresponding memory contents are sequentially erased as the subtractions are performed. The magnetic cards used here are issued to each user, storing a code number that can be used to identify each user along with the gas flow rate corresponding to a predetermined amount of money. This allows you to understand and manage usage status. In other words, a magnetic card is held for each user, and the magnetic card stores a user code that does not disappear with each use, and also stores the amount of money that disappears with each use or the corresponding gas flow rate. The memory of the gas flow rate to be extinguished is, for example, 1,000 yen, 2,000 yen, 3,000 yen, or s, ooo yen, io, oo
It corresponds to a well-divided amount with no fractions such as o yen, and in relation to the meter 2, for example, 3
．． 000 yen or 5,000 yen, and the setting is arbitrary. The magnetic card in which the gas flow rate is stored is read by the control unit 6 comprising the reading or calculation mechanism, and the display unit 4
As mentioned above, after displaying a predetermined display and driving the opening/closing mechanism 5, or by sequential subtraction, only the memory contents corresponding to that gas flow rate are erased, and cannot be reused as they are. It is. If you wish to reuse the magnetic card or request a new magnetic card, use an appropriate reproducing device (including a reissuing device) and enter the specified amount so that you can reuse or obtain a new magnetic card. become. As the playback device, for example, an unmanned device similar to a vending machine is used, or a device installed at a financial-related counter or the like where a predetermined amount can be entered using a button. The former vending machine type playback device has a magnetic card insertion slot and a bill slot, and a magnetic card is inserted from a predetermined direction, and a 1,000 yen bill, for example, is inserted into the bill slot. If you continue to insert the money, the accumulated amount will be displayed. For example, when the displayed amount reaches 3,000 yen, if you press the memory button, that amount or the gas flow rate corresponding to the amount will be displayed. stored on the card,
It would be nice to be able to take it out. In addition, the latter input type playback device has a magnetic card insertion slot and an O
9 to 9 buttons are provided, and a person handling the card, such as a bank clerk, receives a specified amount of money and a magnetic card from a customer, inserts the magnetic card from a specified direction, and then receives the card. After inputting the number corresponding to the amount of money and confirming the number on the display, if you press the memory button, the amount or the corresponding gas flow rate will be stored on the magnetic card in the same way as described above. become. In either case of reproducing or reissuing the magnetic card, 1.
．． If you need your old magnetic card and lose it, you will need to have a new magnetic card with a customer code reissued. Also, in the playback device, a display lamp is lit or a sound or voice is used to notify the completion of storage. A magnetic card is played using the above-mentioned playback device, and at the same time as this playback, a unique code of the magnetic card is read, and the amount paid for each code is also memorized.
By having the memory read by a management device such as a predetermined computer, data on gas usage status for each customer can be easily created, and customer management becomes significantly easier. Further, the gas flow rate can be stored by the control unit 6 including the reading or calculation mechanism by integrating the remaining gas flow rate displayed on the display unit 4, and a new magnetic card can be inserted before the gas flow is stopped. This allows for continuous gas flow. The magnetic cards to be used may be handled by, for example, gas companies in prefectures that manage gas, or may be outsourced to financial institutions, supermarkets, tobacco stores, etc. In the above embodiments, gas supply has been described, but it goes without saying that this can also be applied to, for example, water supply or electricity supply. That is, it can be easily applied by simply replacing the shutoff valve with a water stop valve or a circuit breaker, and there is no change in the basic technical idea and problem to be solved.

As explained above, the gas supply system according to the present invention,
A meter that detects the gas flow rate and an M-shape valve are connected to the gas pipe, and the control unit is equipped with a display unit driven by the meter, an opening/closing mechanism that opens and closes the shielding valve, and a control unit, and the control unit is magnetically connected. The memory contents of the card are read and the gas style is set and displayed on the display section based on the read contents, and the gas flow corresponding to the set gas flow rate is performed, and the memory of the magnetic card is canceled. By using a magnetic card, it is possible to distribute the required amount of gas to each household, and in addition, the magnetic card can be recycled or reissued using a designated reproduction or reissuance device, and there is no charge for the reproduction. This means that the traditional meter reading, calculation, and fee collection tasks can be omitted, and the costs involved can be significantly reduced, resulting in a significant reduction in gas prices. It has excellent effects. In addition, a magnetic card stores a unique code number for each household or customer, and when it is played back by a playback or reissue device, the code and amount are stored in a storage unit, and the storage unit is transferred to a computer. By having the information read and stored in a management system such as the above, an excellent effect can be achieved in that the gas usage status of each household or each customer can be managed as data.
