Embodiment
Below with reference to drawing explanation embodiments of the invention.
(embodiment 1)
Among Fig. 1, the coal gas that can be used as fuel supplies in the room by gas piping 8, after gas flow pick-up unit 9 on it and coal gas tripper 10 are set.Here, there is no particular limitation for the position of gas flow pick-up unit 9 and coal gas tripper 10 relation, and the upstream side that coal gas tripper 10 is arranged on gas flow pick-up unit 9 also is fine.
Gas flow pick-up unit 9 is constantly sent into gas flow data all the time in the coal gas implement discriminating gear 11.
In addition, with the tap water use amount data of the gas flow data synchronization of above-mentioned gas flow pick-up unit 9 also from constantly sending into the coal gas implement discriminating gear 11 with the tap water use amount pick-up unit 12 of the tap water meter collaborative work of outside.
Equally, with the electricity usage amount data of the gas flow data synchronization of above-mentioned gas flow pick-up unit 9 also from constantly sending into the coal gas implement discriminating gear 11 with the electricity usage amount detecting device 13 of the ammeter collaborative work of outside.
Since above-mentioned tap water use amount pick-up unit 12 detected tap water use amounts and electricity usage amount detecting device 13 detected electricity usage amounts be with gas flow pick-up unit 9 detect detect when gas flow changes coal gas change before, corresponding value afterwards, therefore, even also be provided with the coal gas setting that other use tap water and electric power, when detecting the changing value of use amount, do not have any difficulty yet.
The following describes operation and effect thereof in the said apparatus.At first, coal gas implement discriminating gear 11 when detecting gas flow and change, will detect coal gas change before and detect the tap water use amount of coal gas after changing and compare, thereby can differentiate the equipment whether gas fittings that is used uses tap water.
In addition, before also when detecting gas flow and change, gas flow being changed and electricity usage amount afterwards compare, thereby can differentiate the equipment that the gas fittings that is used is an electrification.
Female ccontaining speech, all under the occasion of change, then can differentiate gas fittings is the equipment that tap water and electric power all use in tap water use amount and electricity usage amount.In addition, because storage in advance has the flow value data of coal gas, therefore can determine the kind of coal gas implement from these data.
For example, the gas flow value is A, electric power is not used and the also untapped words of tap water, and then can differentiate what be used is coal gas cooking appliances such as gas range; Equally, in the gas flow value when to be B, electricity usage amount for the electricity usage amount of storage in advance and tap water be not used, then can differentiate what be used is the fan-type gas fire; In the gas flow value be C, electric power does not use and the use amount of tap water during for the tap water use amount of storage in advance, and then can differentiate what be used is opening water heater (being small water heater); In addition, in the gas flow value is D, electricity usage amount for the use amount of the electricity usage amount of storage in advance and tap water also is the tap water use amount of storage in advance, and then can differentiate what be used is water heater (as the water heater in the shower set etc.).
In general, all have control function of power in the gas fittings, therefore, preferably set minimum and mxm. respectively for above-mentioned gas flow value, tap water use amount and electricity usage amount.
In addition, though be in the above-described embodiments with the gas fittings that uses tap water and electric power simultaneously as object,, the above embodiments can also be used to differentiate the gas fittings that only uses tap water and the gas fittings of an electrification, this is very obvious.
In addition, can also manage concentratedly delivering to (for example) coal gas central monitoring position from the information that obtains of above-mentioned coal gas implement discriminating gear by network, this is for guaranteeing that safety is extremely effective.
In addition, also can consider to stop after at least one disengaging in gas flow value, tap water use amount and electricity usage amount imposes a condition supplying with coal gas to gas fittings.
Gas flow pick-up unit 9 also can use ultrasonic to measure the flow velocity of coal gas.In addition, elements such as use traffic sensor, fluidic sensor also are admissible.
(embodiment 2)
Among Fig. 2,14 is control device, the gas flow data all the time that this control device 14 is sent gas flow pick-up unit 9 here, from the tap water use amount data of the gas flow data synchronization of tap water use amount pick-up unit 12 gas flow pick-up units 9 that send here and described and the coal gas use amount when the coal gas of the electricity usage amount data of the gas flow data synchronization of electricity usage amount detecting device 13 gas flow pick-up units 9 that send here and described and storage in advance normally uses, the condition of electricity usage amount and tap water use amount is compared, when breaking away from predetermined service condition, make 10 operations of coal gas tripper, with gas cutting.
Because the electricity usage amount that tap water use amount that tap water use amount pick-up unit 12 detects and electricity usage amount detecting device 13 detect is before gas flow changes when detecting gas flow and change with gas flow pick-up unit 9 and changes the corresponding use amount in back, therefore, even also be provided with other gas fittings that use tap water and electric power, detect and get up also not have what difficulty.
In addition, be set with minimum and mxm. respectively for described gas flow value, tap water use amount and electricity usage amount.Like this, can when being provided with control function of power, gas fittings be convenient to differentiate.
The following describes the operational circumstances and the effect thereof of coal gas tripper with above-mentioned formation.
Bring into use preceding tap water use amount to compare by tap water use amount after coal gas is brought into use and coal gas, and the electricity usage amount after similarly coal gas being brought into use and the coal gas electricity usage amount before bringing into use compares, employed tap water use amount of the gas fittings that can obtain being used and electricity usage amount, meanwhile, the flow value data of coal gas also can obtain.
These coal gas use amount data, tap water use amount data and electricity usage amount data are compared with the value that is stored in advance in the control device, as note abnormalities, and then make 10 operations of coal gas tripper, with gas cutting.
In the prior art, owing to only differentiate the user mode of coal gas implement according to the use amount information of coal gas, when use-pattern is unusual, then with gas cutting.Therefore for different types of gas fittings, just can't differentiate, so the ability that prevents of coal gas accident is limited to coal gas implement.After adopting the above embodiments, such problem just can effectively solve.
For instance, since the gas flow when using much at one the gas fire tool and the behaviour in service of coal gas cooking device can be distinguished, therefore continuous band service time (being used to judge whether to cut off the continuous service time of coal gas) of gas fire tool and coal gas cooking appliance can be distinguished.So, the coal gas accident can significantly reduce.
In addition, though be in the above-described embodiments with the gas fittings that uses tap water and electric power simultaneously as object,, the above embodiments can also be used to differentiate the gas fittings that only uses tap water and the gas fittings of an electrification, it is quite obvious.
In addition, the information that obtains from above-mentioned control device 14 can also be delivered to (for example) coal gas central monitoring position by network and manage concentratedly, this is for guaranteeing that safety is effective measures extremely.
And the same with embodiment 1, gas flow pick-up unit 9 also can use ultrasonic to come the flow velocity of instrumentation coal gas, perhaps devices such as use traffic sensor, fluidic sensor.
In sum, adopt words of the present invention, the behaviour in service by handling gas fittings simultaneously and the use amount data of tap water and/or electric power can be determined the coal gas implement that is used, to the setting of can opening circuit of every kind of coal gas implement, thereby can significantly improve the security of coal gas when using.
