See also Fig. 4, Fig. 4 is the operational flowchart of first embodiment of the invention, and please cooperates earlier figures 1 to Fig. 3 simultaneously, and just the operational flowchart of preferred embodiment of the present invention work one is described as follows now.
Holding vessel 5 is after having supplied gas, and the user can be sent to it directly new holding vessel of exchange of switching station.Can directly inflate or it is transported to the dealer by switching station and locate inflation.The holding vessel that holding vessel 5 then can be concentrated to switching station or dealer place is store among the district A1 temporary temporarily, in the time will inflating management, it is transported among the A2 of pre-process working area again, carries out pre-sorting in the time of if necessary earlier.See through identifying information transmitting set 2 (being a radio frequency identification read-write equipment in the present embodiment) by the processing unit 11 of control gear 1 and read and be disposed at the holding vessel Information ID (step 101) in the information identification tag 6 on the holding vessel 5 this moment, to obtain holding vessel sequence number No., build date D, holding vessel net weight Wt, gas storage amount W0, inflation times N or gas storage material category etc.
After reading the holding vessel Information ID, by processing unit 11 according to the holding vessel Information ID, with reference to system parameter data storehouse DB stored in the storage unit 12 to holding vessel 5 classify (step 102), judge specification, the type of holding vessel 5 thus, use learn its supplemental characteristics such as calibrating gas storage volume Ws, gas storage material category K of corresponding venting condition or corresponding specification.
Then, in the A2 of pre-process working area, holding vessel 5 is carried out tank body safety verification and classification, to check its whether impaired, gas leakage? (step 103).And the project of tank body safety verification comprises similarly being the airtight test of tank body, tank body deformation detection, the damaged detection of tank body etc.If when finding that tank body has impaired, gas leakage, then holding vessel 5 is delivered to and is reclaimed check and maintenance (step 104).If tank body is checked when all right, then holding vessel 5 is carried out exterior clean and arrangement (step 105) afterwards, it is transported in the gas recyclers and gas handling equipment 3.
Then, (for example: hydrogen storage tank) be positioned in the tank 32 of gas recyclers and gas handling equipment 3, and connect gas feedthroughs L with holding vessel 5.Then, set the venting condition (step 106) of holding vessel 5 by processing unit 11.In the present embodiment, directly use default inflation pressure value, perhaps take from corresponding inflation pressure value Ps and gas-filling temperature value Ts in the storage unit 12.With this venting condition holding vessel 5 is inflated (step 107) then.
During inflation, the gas that gas source H is provided by gas supply device 31 (for example: hydrogen) be supplied in the holding vessel 5 via pressure regulating unit 311, flowmeter 312.Aspect pressure control: pressure regulating unit 311 is subject to processing unit 11 and controls, and the inflation pressure regulated signal S1 that it produces according to inflation pressure setting value Ps uses the adjusting inflation pressure.
Aspect temperature control: temperature-adjusting device 33 also is subject to processing unit 11 and controls, it produces a gas-filling temperature control signal S2 according to gas-filling temperature setting value Ts, with 331 starts of control cooling unit cold rinse bank 332 is cooled off, and then the water 321 in the tank 32 is cooled off, (for example: hydrogen) be beneficial to inflation.Simultaneously, processing unit 11 sees through temperature sensor 322 and comes water temperature value T in the sensing tank 32, cooperates control temperature-adjusting device 33 according to this, so that the temperature maintenance during holding vessel 5 inflations is under gas-filling temperature setting value Ts.
On the other hand, the gas flow F when processing unit 11 sees through 5 inflations of flowmeter 312 monitoring holding vessels, it is full to judge by this whether holding vessel 5 has filled? (step 108).When gas flow F was higher than flow of aerating air reference value Fs, it was full to represent that then holding vessel 5 is not filled as yet, then continues to inflate; If when gas flow F was lower than flow of aerating air reference value Fs, it was full to represent that then holding vessel 5 has been filled, then make gas supply device 31 stop supplies gases this moment, and temperature-adjusting device 33 also stops operation simultaneously.
Holding vessel 5 then is transported among the detection zone A3 after inflation finishes, with detect its inflation after gas storage amount W (step 109).In the present embodiment, carry out weighing by the holding vessel 5 after the 4 pairs of inflations in weight measurement unit, be resent in the processing unit 11 to obtain a holding vessel weight W f, and processing unit 11 deducts the holding vessel net weight Wt that is read in the previous storage unit 63 by information identification tag 6 with holding vessel weight W f, promptly tries to achieve gas storage amount W (Wf-Wt=W).
Then, upgrade holding vessel Information ID (step 110) in the storage unit 63 that is stored in information identification tag 6 with this gas storage amount W; Certainly, other similarly is that information such as inflation times N also can be upgraded simultaneously according to need.
Because in preferred embodiment of the present invention, information identification tag 6 is a wireless radio frequency identification mark, so can upgrade the holding vessel Information ID.Yet except that upgrading, the data of holding vessel 5 after gas replenishment process and inflation finish also can be stored among the DB of system parameter data storehouse according to need, are convenient to review, when this holding vessel 5 is sent here inflation once more in the future, the inflation data in its past then have mark to follow, and help to inflate the improvement of management quality.
When practical application, also can be only with these data storage in the DB of system parameter data storehouse, and the holding vessel Information ID is not carried out Data Update, not more under the news, information identification tag 6 just not necessarily will be used the wireless radio frequency identification mark with read-write capability, also can use the label of the class of bar code to show relevant information.
After the renewal of holding vessel Information ID finishes, processing unit 11 is compared calibrating gas storage volume Ws corresponding among gas storage amount W and the system parameter data storehouse DB, differentiate gas storage amount W in the present embodiment and whether reached 80% of calibrating gas storage volume Ws? (step 111).And assess the standard volume how much gas the normal storage jar can store with calibrating gas storage volume Ws, by this as the foundation of its gas storage capability.That is when the detected gas storage amount W in inflation back is lower than calibrating gas storage volume Ws with certain proportion, represent that then the gas storage capability of holding vessel 5 has tangible decline, then need this moment the holding vessel 5 of below standard standard is delivered to recovery check and maintenance.
When gas storage amount W have reach calibrating gas storage volume Ws 80% the time, represent that then the gas storage capability of holding vessel 5 is normal, just it can be transported to package handling district A4 and pack (step 112), install holding vessel 5 additional protecting jacket.Again it is transported and be back to holding vessel and store district A1 temporarily, preparing that holding vessel 5 is delivered to switching station (step 113), or other commutating devices or supply center, so that being provided, the user uses.
