The figure of all visible automatic vending machine such as place.
The life that automatic vending machine gives people brings great convenience, but there is also some problems, such as：Work as automatic selling
Inside cargo aircraft during shipment, shipment device can not precisely shipment, cause unnecessary loss or trouble, then need be to shipment device
It is no precisely shipment to be detected, it is ensured that shipment function is normal.
Utility model content
The purpose of this utility model is to provide a kind of detection whether effective circuit of shipment electromagnet, solution background technology
Middle the problem of.
The utility model is realized using following technical scheme：
One kind detection whether effective circuit of shipment electromagnet, including a relay, its common port are connected with normal-closed end, and one
First resistor and a second resistance, the two series connection, wherein first resistor one end are connected with relay, one first diode, its
Positive pole is connected with second resistance one end, and negative pole is connected with one end of shipment electromagnet coil, one second diode, one the 3rd 2
Pole pipe and one the 4th diode, three's series connection, its negative pole are connected with the first diode cathode, positive pole and the first diode cathode
It is connected, a 3rd resistor, its one end is connected with the first diode cathode, the light-emitting diodes of the other end and a photoelectrical coupler
Pipe positive pole is connected, and the light emitting diode negative pole of the photoelectrical coupler is connected with the first diode cathode, its photo-sensitive cell
It is connected with the central controller of automatic vending machine.
By such scheme, this practicality at least has advantages below：The utility model is solved in automatic vending machine shipment
Just it can detect whether shipment electromagnet is connected before, whether junction contacts are good, can have been reflected whether in shipment action process
Electric current, substantially increases the shipment precision and reliability of automatic vending machine.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and can be implemented according to the content of specification, it is described in detail below with the utility model legend.
Brief description of the drawings
Fig. 1 is the utility model circuit diagram.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to Fig. 1 one kind detection whether effective circuits of shipment electromagnet, an including relay K1, its common port with it is normally closed
End connection, a first resistor R256 and a second resistance R257, wherein the two series connection, first resistor R256 one end and relay K1
It is connected, one first diode D52, its positive pole is connected with second resistance R257 one end, negative pole and shipment electromagnet coil L1-Ln
One end be connected, one second diode D51, one the 3rd diode D53 and one the 4th diode D54, three series connection, its negative pole
It is connected with the first diode D52 positive poles, positive pole is connected with the first diode D52 negative poles, a 3rd resistor R254, its one end
It is connected with the first diode D52 negative poles, the other end is connected with the light emitting diode positive pole of a photoelectrical coupler U46, described
Photoelectrical coupler U46 light emitting diode negative pole is connected with the first diode cathode, its photo-sensitive cell and automatic vending machine
Central controller is connected.
It is worth noting that：This circuit does not show what photoelectrical coupler was connected with the central controller of automatic vending machine
Part, including relay K2-Kn for whether being powered of all electromagnet coil L1-Ln of control are also by central controller controls, these
Technology is not belonging to the art of this patent category, and this patent is not shown.
Be in and be stopped state in process of self-test repeat circuit K1, common port is connected with normal-closed end, power supply by R256,
R257, D51, D52, D53, D54, Ln, Kn formation loop, when AC power positive half cycle, power supply is produced by D52 thereon
The very low reverse pressure voltage for being not above photoelectrical coupler U46 of pressure drop, when power supply negative half period, electric current is produced by D51, D53, D54
Raw more than 2V pressure drop, this voltage by R254, U46 formation loop U46 can be turned on.When U46 conductings, then its is photosensitive
Element can produce electric current, and because photo-sensitive cell is connected with the central controller of automatic vending machine, central controller just can be sentenced
Break and coil Ln connections, then judge that shipment electromagnet is effective.
Electromagnet if necessary to detection is disconnected, or is not existed, and that cannot form loop, and such U46 is just
It can not turn on, system can just detect electromagnet work not yet in effect.
General principle of the present utility model and principal character and advantage of the present utility model, one's own profession has been shown and described above
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model, the utility model
Claimed scope is by appended claims and its equivalent thereof.
