In addition, as mentioned above, the related fuel gas measuring device 100 of present embodiment is configured in the situation that surpass the use traffic of the combustion gas allowing and cuts off combustion gas pipe arrangement 101.Therefore, with reference to Fig. 4, illustrate that the cut-out of the combustion gas pipe arrangement 101 in the situation of use traffic of the combustion gas surpass allowing processes (fuel gas shutoff is processed (A)).Fig. 4 means the process flow diagram of an example of the fuel gas shutoff processing (A) of being implemented by the related fuel gas measuring device 100 of present embodiment.
(fuel gas shutoff is processed (A))
When combustion gas pipe arrangement 101 uses combustion gas for open mode, every use ormal weight (for example 5 liters) by metering portion 1 to supply control part 3 delivery rate pulses.As shown in Figure 4, in supply control part 3, when master control part 32 receives flow pulse from metering portion 1 (step S21), to being recorded in to supply with to control, with the combustion gas available stream value in storer 34, carry out subtraction, obtain the surplus (step S22) of the combustion gas available stream value of current time.Then, master control part 32 makes LCD display part 33 show the surplus of obtaining.
In the present embodiment, for example every 5 liters receive flow pulse from metering portion 1, so the surplus of combustion gas available stream value is that 5 liters of every uses are once upgraded.Like this, 32 pairs of master control part are recorded in to supply with to control carries out subtraction with the combustion gas available stream value in storer 34, judges whether the surplus of combustion gas available stream value is zero (step S23).Repeated execution of steps S21 and step S22 are until be judged as the surplus vanishing of combustion gas available stream value.(step S23: "Yes"), valve signal (step S24) is closed in 2 outputs to stop valve when the surplus that on the other hand, is judged as this combustion gas available stream value when master control part 32 is zero.Stop valve 2 closes valve signal according to this and cuts out combustion gas pipe arrangement 101 (S25).Thus, stop supplying with combustion gas.
In addition in the related fuel gas measuring device 100 of present embodiment, if also can be configured to the surplus of combustion gas available stream value, be that ormal weight is warned with next output.In addition, can also be following structure: if the surplus of combustion gas available stream value is zero, further represent it is zero notice.These warnings and expression are that zero notice can be shown by LCD display part 33, also can be configured to not shown audio output unit is set and notifies by sound.Can also be not shown light output part to be set, the structure of notifying by luminance.
Like this, in the situation that because the surplus of combustion gas available stream value is the zero combustion gas that stops supplying with, in the related fuel gas measuring device 100 of present embodiment, can be by again the storage card 8 that records combustion gas available stream value being inserted to the supply that again recovers combustion gas in card insert opening (not shown).In addition, describe in detail in the back from process the state of (A) cut-out combustion gas pipe arrangement 101 by fuel gas shutoff and again recover the Recovery processing (Recovery processing (A)) of the supply of combustion gas.
In addition, also be configured to following structure: although there is the state of surplus in combustion gas available stream value, but receive cut-out indicator signal from security facilities 5 in the situation that, the master control part 32 of supply control part 3 sends and closes valve signal to stop valve 2 according to this signal.Then, stop valve 2 closes valve signal according to this and cuts out combustion gas pipe arrangement 101.
That is, in the related fuel gas measuring device 100 of present embodiment, be configured to minute be arranged supply control part 3 and security facilities 5, stop valve 2 is only according to indicating to open and close from the control of supply control part 3.Therefore,, in the situation that security facilities 5 detect the abnormal use of combustion gas, be not directly to indicate stop valve 2 to close combustion gas pipe arrangement 101 from security facilities 5, but indicate by supply control part 3.
Therefore, below with reference to Fig. 5, Benq processes (fuel gas shutoff is processed (B)) in the cut-out of the combustion gas pipe arrangement 101 of the abnormal detection of using of combustion gas of security facilities 5.Fig. 5 is that the figure of an example of (B) is processed in explanation by the fuel gas shutoff of related fuel gas measuring device 100 enforcements of present embodiment.
(fuel gas shutoff is processed (B))
When combustion gas pipe arrangement 101 uses combustion gas for open mode, every use ormal weight (for example 1.2 liters) by metering portion 1 to security facilities 5 delivery rate pulses.In security facilities 5, when security receives flow pulse with control part 52 from metering portion 1 (step S31), the historical record of flow pulse is recorded in to security with in storer 53.Then, the historical record of this flow pulse based on recorded, security judges whether to exist the abnormal use (step S32) of the combustion gas such as gas leakage with control part 52.In step S32, be judged as "No" during, continue to carry out the reception of the flow pulse in step S31, when being judged as "Yes" in step S32 (, when being judged as the abnormal use that produces combustion gas), security exports cut-out indicator signal to supply control part 3 (step S33) with control part 52.In supply control part 3, when master control part 32 receives cut-out indicator signal from security facilities 5, to stop valve, valve signal (step S34) is closed in 2 outputs.When receiving this and close valve signal, stop valve 2 cuts out combustion gas pipe arrangement 101.
As mentioned above, even if there is the state of surplus in combustion gas available stream value, in the security of security facilities 5, with control part 52, be judged as and in combustion gas is used, produce abnormal in the situation that, also can control stop valves 2 by supply control part 3 and cut off combustion gas pipe arrangement 101.
In addition, at above-mentioned fuel gas shutoff, process in (B), whether the historical record that security flow pulse based on receiving from metering portion 1 with control part 52 has been described judges whether to exist the structure of the abnormal use of combustion gas, but exist the judgement of the abnormal use of combustion gas to be not limited thereto.Security facilities 5 are configured to vibration sensor 6 and are connected with warning horn 7, in the situation that receive expression from vibration sensor 6, sense the signal of the meaning of vibration and the signal that detects the abnormal meaning from the expression of warning horn 7, also think in combustion gas is used, to have produced abnormal and export cut-out indicator signal to supply control part 3.
Then the state, the following describes from utilizing stop valve 2 to close combustion gas pipe arrangement 101 by above-mentioned fuel gas shutoff processing (A), (B) is opened the Recovery processing (Recovery processing (A), (B)) that combustion gas pipe arrangement 101 returns to the state of supplying with combustion gas.
First, as Recovery processing (A), with reference to Fig. 6 explanation, by " fuel gas shutoff processing (A) ", cut off the Recovery processing in the situation of combustion gas pipe arrangement 101.Fig. 6 is that explanation is by the figure of an example of the Recovery processing (A) of related fuel gas measuring device 100 enforcements of present embodiment.
(Recovery processing (A))
