Description
It is the IC-card formula fuel charger that motor vehicles add light fuels such as gasoline, diesel oil that the utility model relates to a kind of microcomputerized control refuelling station that adopts.
In recent years, IC-card formula computer fuel charger had begun to be applied in each refuelling station, and its structure mainly is made up of computer control head 11 and mechanical oil mass output control 12 two large divisions as shown in fig. 1.Its computer control head part 11 mainly comprises singlechip controller 111, keyboard controller 112, fuel monitor 113 and IC-card read-write equipment 114, and its mechanical oil mass output control part 12 mainly comprises motor 121, oil pump 122, flowmeter 123, fuel-displaced flow sensor 124 and oil gun 125.Machinery oil mass output control part 12 actuating motor 121 under the control of computer control head part 11 drives oil pump 122 then, oil mass flows out from oil gun 125 through flowmeter 123 by oil pump, for the user refuels, fuel-displaced flow sensor 124 converts oil pump capacity to the singlechip controller 111 of pulse signal sending computer control head part 11 for detecting.Computer control head part 11 is read the IC-card that the user inserts by IC-card read-write equipment 114, confirming that actuating motor 121 refuels for the user under the effective condition of IC-card, and by the counting of fuel-displaced flow sensor 124 output pulses being realized metering to volume read-out, after oiling finishes, in IC-card, write the remaining sum after clearing.
Above-mentioned IC-card formula computer fuel charger all is to adopt static read-write mode to the read-write of IC-card, and its concrete operations step is: a. inserts IC-card; B. operation push-button is set unit price, density etc.; C. press start key, manually send the Card Reader signal; D. inserting oil gun refuels; E. manually press stop key, send IC-card clearing signal; F. extract IC-card.If will all be regarded as " illegal operation " and not admit in advance by computer fuel charger not according to above-mentioned 6 steps operation.Because button hand-manipulated is many and will satisfy certain sequence, therefore using IC-card to refuel needs full-time oiling person's operation usually, rather than is refueled with card by driver oneself, has lost the meaning of using IC-card to refuel to a certain extent.
The purpose of this utility model is a kind of non-keying formula IC-card computer fuel charger of design, can adopt " fool " mode of on-keyboard operation, during fuel charger work, only IC-card need be inserted in the deck and just can refuel, the user only need make three actions, be that plug-in card, access oil gun refuel and pull out card,, make the driver just can refuel the execute-in-place oiling owing to needn't contact keyboard fully.
The utility model be by assembly abandon IC-card static read-write mode, adopt dynamic read-write technology to realize purpose of design, thereby 6 step operation changes that can be original be to operate in 3 steps, and needn't operate any button.
Thick film circuit module (Jutong Network Co., Ltd., Beijing production of a kind of model of using in multiple rate (electricity charge changed with the electricity consumption time) taximeter of electric power as ZZX is arranged, separate case application patent of invention), be one with the time substrate 555 timing circuits be the high-speed counter of core component, use this product and make and realize that purpose of design of the present utility model becomes possibility.
The purpose of this utility model is to realize like this, non-keying formula IC-card computer fuel charger, comprise singlechip controller and the oil pump capacity display, flow sensor, motor, IC-card read-write equipment and the IC-card seat that is connected with the IC-card read-write equipment that are connected with singlechip controller, it is characterized in that: described IC-card read-write equipment is the thick film circuit module that can dynamically read and write the IC-card in the IC-card seat, and described flow sensor output terminal also connects described thick film circuit module.
Described thick film circuit module is the ZZX module that has 30 pins, is of a size of 30 * 55 * 10 millimeters, the pulse output end of its count pulse input end connection traffic sensor, its read-write operation end connects the IC-card seat, and its data terminal, address end and control end connect described singlechip controller respectively.
The utility model is made the IC-card read/write circuit by adopting ZZX thick film circuit module, make the static state read-write process of IC-card become dynamic read-write process, thereby realized the oiling of 3 steps, it is plug-in card, insert oil gun and refuel and pull out card, neither one button operation step, the driver inserts IC-card and can refuel, computer is settled accounts automatically after closing oil gun, greatly facilitate the user, alleviated the worker's of refuelling station labour intensity, made refueling process simple, clearly, fast and accurately, owing to only the IC-card read-write equipment in the former IC-card computer fuel charger is replaced to a thick film circuit module, therefore needn't carry out big transformation to former fuel-servicing equipment, implement easily.
