Definitions

  • the invention relates to an apparatus for metering and dispensing gas.
  • U.S. Patent No. 4,838,404 a microcomputer system is described, which is operated by a token. Upon inserting a token power is supplied to a device, for example to a TV set, for a period corresponding to the token.
  • the optical detector of the apparatus, receiving the token is designed in a way that a token of predetermined shape and coding can be inserted into the device in any position.
  • Hungarian Patent No. 191 ,762 an electronic consumption metering system was described, in which the utilities consumption is measured on site by counting the number of pulses proportional to the consumption, followed by forwarding the measuring results automatically to a data processing center at regular periods, for example every month, through a telecommunication system. In this way human reading can be absolutely omitted.
  • the data network must be built for each individual consumption meter, which is extremely costly for example in the case of household consumption.
  • the auxiliary electric power is not always available, and even if it is, the implementation of an electric link-up is troublesome and/or expensive. Furthermore, it is not advantageous if the consumption metering and dispensing of one utility becomes impossible in case another utility eventually breaks down.
  • conventional electrically controlled shut-off devices e.g. magnetic valves, consume a substantial rate of power, so that they cannot be operated from an electric battery for a long time.
  • the invention is an apparatus for metering and dispensing gas, comprising a shut-off device for the gas to be consumed, means for receiving consumption signals corresponding to the gas consumption, a card reader for reading data cards storing data corresponding to a predetermined quantity of gas and a control unit having a microprocessor for controlling the shut-off device.
  • the shut-off device comprises a valve to be inserted into a conduit of the gas, said valve having a housing and being actuated through a low friction moving mechanism by a stepping motor, said stepping motor being located outside the housing of the valve, and there is a sealed magnetic coupling to transfer rotation between the stepping motor and the moving mechanism, said stepping motor being controlled by the control unit according to the gas consumption and to signals read from a data card.
  • the actuating mechanism for the valve ensures a low electric power consumption. Neither in the open position, nor in the closed one is there any power consumption for the actuating mechanism. Only the electronic control unit has a very low power consumption. Therefore, the apparatus according to the invention can be operated for a long time without any maintenance using batteries available from trade.
  • the moving mechanism comprises a first cam device for closing the valve and a second cam device for opening the valve, said first and second cam devices being fastened to a shaft running on ball bearings, said shaft being rotated by the stepping motor.
  • the moving mechanism further comprises a case fixed to the housing of the valve, a frame slidable mounted within the case, said frame being moved by the first and second cam devices, and the first and second cam devices comprise ball bearings as rollers, said ball bearings having shafts fixed to the frame.
  • the valve comprises a valve seat fixed to the housing and a valve body fixed to the frame through a valve plate, said valve body being made of rubber and provided with air pockets.
  • control unit adds the quantity corresponding to the signals read from a data card by the card reader to a stored quantity available for consumption, reduces the stored quantity in accordance with the received consumption signals, and if the stored quantity decreases to zero, closes the valve and if the stored quantity is higher than zero, keeps the valve open or opens it. It is a benefit of the invention that the data card giving eligibility for consumption is available for reading both during and before/after consumption.
  • the apparatus further comprises a pushbutton for enabling the card reader and a display connected to the control unit for indicating the amount of gas available for consumption and error messages corresponding to states of the control unit.
  • the current amount of gas available for consumption is displayed for a short period upon actuating the pushbutton, and error messages eventually arising during operation appear also for a short period, e.g. for some seconds.
  • control unit only adds the quantity corresponding to the signals read from the data card to the stored quantity available for consumption if the increased quantity is lower than a predetermined limit value, otherwise no addition is carried out and a first error message is issued. This is so as it may not be desirable in some cases, e.g. with respect to increase of tariff rates, that the consumer is enabled to accumulate an excessively large consumption quantity in his apparatus.
  • control unit In safety respect it is advisable for the control unit to turn off the valve and to issue a second error message if the value of gas consumption per unit of time is over a predetermined value. In this way, e.g. in the case of a high gas leakage, the apparatus automatically shuts off the gas.
  • a gas consumption system easy to handle can be established if the control unit has a data memory for storing an apparatus identifier for matching the apparatus and the applicable data card and a sequence number of the data card read most recently, and that the control unit only adds the quantity corresponding to the signals read from the data card to the stored quantity available for consumption, if the apparatus identifier read from the data card corresponds to the stored apparatus identifier and its sequence number is higher ihan that of, the data card read most recently.
  • the gas company increases; Ihe data card's sequence number by one, each time the data card is "validated" against payment.
  • the service pcovider receives information on the consumption of each consumer and security is also granted against any use of the data card at another consumer if it is lost or stolen.
  • the control unit adds a constant quantity to the stored quantity available for consumption if the valve is closed and the data card of a sequence number not higher is read for the first time, otherwise no addition is made and a third error message is issued. Monitoring whether the reuse of a data card already used for such a reserve purpose happens for the first time prevents any abuse.
  • control unit is switched from a stand-by state to an active state upon reading a data card or upon receiving a consumption signal, in said active state the control unit processes the signals received and in predetermined cases controls the valve, then returns to the stand ⁇ by state.
  • control unit is in a stand-by state in most of its operating period, and in the stand-by state its electric power consumption is very low, in fact only a fraction of that in the active state.
  • control unit comprises software means for resetting the control unit from the active state to the stand-by state. In this way, after each activation, having carried out the data handling and processing task, the control unit is immediately pushed into the stand-by state. This action results in a very low auxiliary electric power consumption.

In this case it may happen that the user does not have a data card validated for further consumption and because of a week-end or holiday period he cannot validate his data card for a time. In order to make sure that no pause occurs in such cases in the use of equipments supplied by gas, it is advisable to allow the reuse of the most recently applied data card without validation, on a one time basis, for a "credited" consumption of reserve (e.g. a predetermined value in the range of 10-50 m 3 ). To this end, if the sequence number of the inserted data card 66 is not higher than that of the card used before, it is examined in steps 102 whether the valve 74 is closed.

If not, step 109 above follows. If it is the same, in step 105 the reserve quantity is added (accumulation) and the fact of using the reserve is written in. Then, operation continues in step 110 with the opening of valve 74.
  • step 93 If in step 93 it is found out that start-up 78 was not caused by pressing of the pushbutton 5, the only case remaining is when start-up 78 has been caused by a kind of emergency signal.
