Abstract
The utility model relates to the coin remainder detecting device of a kind of coin exchanger, including place the coin storing box of coin, it is provided with the rotating disk of conveying coin and the motor of driving rotating disk rotation bottom coin storing box, also include the gripper shoe for supporting coin storing box, rotating disk, motor, gripper shoe is provided with a pressure sensor, and pressure sensor is connected to central processing element through an AD conversion chip.The utility model detects coin actual weight in coin storing box in real time by pressure sensor, then is calculated residue number of coins by single-chip microcomputer, and coin surplus testing result accurately and reliably, effectively reduces coin exchanger error generation rate, improves Consumer's Experience sense.
Description
Technical field
The utility model relates to coin exchanger parts, the coin surplus of in particular a kind of coin exchanger
Detection device.
Background technology
In daily life, have many places to need to use the place of unitary change or coin, such as by bus or
, often there is forgetting the awkward moment with change, and bus do not have the place of small change in subway, hand-car, slot machine etc.,
Subway station is usually also required to queuing and exchanges for.So one can the machine of coins charge banknotes automatically, can greatly facilitate ours
Life.Before coin exchange, coin exchanger is if not done by judging whether coin surplus enough realizes that equivalence is exchanged, especially
The mistake easily producing, has a strong impact on the use enthusiasm of user.
Content of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides the coin residue amount detection device of a kind of coin exchanger
Put.
For achieving the above object, technical solution of the present utility model is, the coin surplus of a kind of coin exchanger
Detection device, including place the coin storing box of coin, is provided with the rotating disk of conveying coin and the electricity driving rotating disk to rotate bottom coin storing box
Machine, also includes the gripper shoe for supporting coin storing box, rotating disk, motor, and gripper shoe is provided with a pressure sensor, pressure sensor
It is connected to central processing element through an AD conversion chip.
Preferably, pressure sensor is resistance strain type pressure sensor.
Preferably, AD conversion chip is HX711.
Preferably, central processing element is STC series 51 single-chip microcomputers.
By using above-mentioned technical scheme, the beneficial effects of the utility model are: the utility model passes through pressure sensing
Device detects coin actual weight in real time, then is calculated residue number of coins by single-chip microcomputer, coin surplus testing result accurately and reliably,
Coin exchanger error generation rate can be effectively reduced, improve Consumer's Experience sense.
Brief description
Fig. 1 is circuit frame figure of the present utility model；
Fig. 2 is structural representation of the present utility model；
(the 1st, pressure sensor；2nd, AD conversion chip；3rd, central processing element；4th, coin storing box；5th, rotating disk；6th, motor；7th, prop up
Fagging；).
Detailed description of the invention
Further illustrate the utility model below in conjunction with the drawings and specific embodiments.
The utility model belongs to the partial devices constituting coin exchanger, for detecting the surplus of coin in changer.
When coin exchanger receives bank note, the advanced row of coin exchange chance determines whether that enough coins are this time exchanged,
When coin surplus is enough, just exchange, otherwise will not carry out and return to bank note.
As shown in Figure 1-2, the 4th, the coin remainder detecting device of a kind of coin exchanger, including place the coin storing box of coin
Carry the rotating disk 5 of coin and for supporting the gripper shoe 7 of coin storing box the 4th, rotating disk 5 and motor 6, bottom gripper shoe 7, be provided with a pressure
Force snesor 1, pressure sensor 1 is connected to central processing element 3 through AD conversion chip 2.Wherein pressure sensor 1 should for resistance
Variant pressure sensor, has and is quick on the draw, and precision degree is high, lower-price characteristic.AD conversion chip 2 uses HX711
, the HX711 of sea core science and technology is a 24 the A/D converter chips aiming at high-precision electronic scale and designing.With same type its
Its chip compares, this integrated chip include voltage-stabilized power supply, on-chip clock oscillator etc. other with outside required for type chip
Enclose circuit, there is the advantages such as integrated level height, fast response time, strong interference immunity.Central processing element 3 is STC series 51 monolithics
Machine.During the utility model initializing set, first pressure sensor 1 is measured coin storing box the 4th, the rotating disk 5 of zero load and motor 6 in advance
Gross weight is simultaneously stored, and the central processing element 3 of this device is surplus in just can measuring coin exchanger quickly and accurately afterwards
The actual gross weight of remaining coin, then by actual gross weight except in the weight (6.05g) of each coin, residue coin can be learnt
Quantity.
Above-described, preferred embodiment only of the present utility model, it is impossible to limit the model that the utility model is implemented
Enclosing, every equalization made according to the utility model claim changes and decoration, all should still fall within the utility model and cover
In the range of.
