Description
The utility model relates to the liquid fuel field of measuring techniques, mainly proposes a kind of computer oiling detecting device.
Motor vehicle need replenish oil plant and continue to travel again in the way of travelling when fuel oil will exhaust.Each replenishing what of oil plant quantity, is that fuel charger measuring apparatus counting by the casual uplift station is for purchasing unique payment authority of oily person.Many owners of refuelling station utilize technological means without authorization under the constant situation of flow, and the increase reading that revs up reaches the purpose of overcharging debt; Perhaps mix other liquid and sell to the driver, the deception consumer as fuel oil.
The utility model proposes the purpose of computer oiling detecting device, promptly be to overcome the behavior of engaging in fraud for selfish ends, practising fraud that existing refuelling station exists.
The utility model is finished the technical scheme that its invention task takes: be made up of the quick dop of straight cutting, computer count flowmeter and fuel oil and other liquid identification device; The computer count flowmeter is to be made of tubular shell, impact damper, guiding device, turbo blade sensor, magnetic induction signal generator, adjusting gear, electronic counter, a zero clearing and accumulative total reset button, fuel oil and other liquid identification device etc. embedded or the outer attaching permanent magnet of circumferential edge.
Computer refuels detecting device and refuels detecting device and partial installation formula computer and refuel two kinds of structures of detecting device and form by taking computer certainly.
One, take computer oiling detecting device certainly:
One end of the quick dop of straight cutting is connected with the oil gun oil-out of fuel charger; The other end is connected with the oil-in of taking computer oiling detecting device pipe shape housing certainly.The oil-feed oral-lateral of pipe shape housing tube cavity is adorned one bag of shape multiple layer metal fine-structure mesh sheet or porous honeycomb circle bag shape shower nozzle impact damper.By pipe shape housing straight length, near sensor embedded or the outer attaching turbo blade of circumferential edge, the oil-feed side is installed column type and is shaped on the guiding device of pod apertures.The medial surface of the cylindric guiding device that is shaped on pod apertures is same axially, turbo blade embedded or the outer attaching permanent-magnet block of circumferential edge is installed, the oil product inflow tubular shell that nozzle is injected rotates by the oil stream promotion of impact damper guiding device turbo blade embedded or the outer attaching permanent-magnet block of circumferential edge, and oily flow is healed big turbo blade rotation sooner.
The magnetic induction signal generator, permanent-magnet block embedded by turbo blade or the outer attaching of circumferential edge is formed with the tongue tube or the Hall switch that are placed in the shell wall side.Tongue tube is by two kinds: (1) is that a pair of soft iron contact of often opening is fixed in the sealed glass pipe; (2) be in the cylinder spiral coil, to adorn the good iron core of a magnetic conduction, be fixed in the sealed glass pipe.Hall switch is a kind of device that magnetic field intensity is played the action reflection between certain numerical value.
The shell of computer oiling detecting device is to be made by non-magnet material.When the embedding of turbo blade neighboring or circumferential edge outside the permanent magnet rotation of attaching near the distance of setting to tongue tube or Hall switch in, if during with tongue tube (1), iron contact is attracted normal battle the in back to be converted to closure by permanent magnet, after turbo blade rotates and leaves setpoint distance, iron contact recovers often to open, and " open-close-Kai " constituted a pulse signal like this.If during with tongue tube (2), close to the distance of setting when the permanent magnet rotation of turbo blade neighboring embedding, permanent magnet has magnetized the soft iron core in the cylinder spiral coil, when turbo blade rotary permanent-magnet iron leaves desired location, and the magnetization end.The every magnetization of soft iron core once, spiral winding is just responded to a pulse signal.
Hall switch, turbo blade rotation permanent-magnet block, revolution is to the distance of setting, and Hall switch moves once, promptly amplifies a pulse signal.
Make signal generator according to above principle, need be by design at several permanent magnet cylinders of attaching outside turbo blade periphery or circumferential edge to satisfy technical requirement.
The liquid crystal electron counter is by Pyatyi di-～decimal coded counter, single-chip microcomputer UPC control, lcd driver, digital display screen, a zero clearing and accumulative total reset switch and adjusting gear, power supply formations such as (rechargeable batteries).
The counter works principle is to become the transformation of speed of revolving wormgear electric impulse signal to send into amplifier, give single-chip microcomputer UPC control after the amplification integer and carry out+20%～-20% standard signal comparison operation and input to driver, make the digital and electronic rolling counters forward, finish 5 decimal system countings.
Fuel oil and other liquid identification device: be to send into amp.in at electric impulse signal to install semiconductor recognition component and on-off circuit additional, the characteristic of this element is, when fuel oil was flowed through element, this element action made the input signal conducting, and the digital and electronic counter shows counting; If flow through then this not conducting of element of other liquid, there is not input signal, the digital and electronic counter does not have numeral to show.
Two, partial installation formula computer oiling detecting device is that the quick dop of straight cutting is installed in car or other oil tank of vehicle oil-in place.Impact damper, guiding device, turbo blade sensor, signal generator, fuel oil and other liquid identification device five parts embedded or the outer attaching permanent magnet of circumferential edge are integrated and are installed in the straight-line segment of car and other vehicle oil-in and fuel tank intermediate conduit.Digital and electronic counter, adjusting gear, a zero clearing and accumulative total zero clearing four parts are formed an instrument, be installed on the interior panel board of car, instrument display part and Sensor section are connected with two shielded cables in the car, the fuel oil that makes the sensor of flowing through display digit on the instrument in car.
The utility model computer refuels detecting device to be had and connects quick, cheap, simple in structure, accurate measurement, intuitive display, advantage such as easy to use.
