Because a vending machine has a plurality of pallets of selling goods, thereby there is the situation of more code-disc perception component, can there is the more I/O chip of the I2C of plurality of programmable address by use on the one hand, meanwhile, at vending machine mainboard side, can adopt the form of multiway analog switch, first choose certain pallet at every turn, then choose certain motor and perception component, like this, can solve in same vending machine, can use the problem of dozens of, up to a hundred the long-range i/o chips of same I2C.
It is problem that aforementioned system example and preceding method have solved the motor spring front end bearing sense motorized adjustment of selling goods.Meanwhile, the method can also for judging whether shipment spring completes the function rotating a circle, and therefore, can cancel in traditional vending machine by contact-making switch judge whether to rotate a circle (releasing to determine spring handle article).
This method can not only make shipment spring rotate a circle, and can also make the angle of spring success rotating 360 degrees/(2^n-1), in Fig. 4, n=3, this technology, then combine with the Cargo Inspection survey technology that falls in vending machine, vending machine control system can successfully be released given article by the mode of a little rotation, can avoid must rotating a circle as traditional vending machine, thereby may release the shortcoming of article more simultaneously.
Based on above-mentioned motorized adjustment method, the vending machine of given configuration before dispatching from the factory for one, because the spring in each goods road of each pallet is determined (comprise the distance of spring diameter, the number of turns, each circle and for the spring at front end initial position that connects bayonet lock), can obtain the original state table of all spring at front ends, simultaneously, again by a preset table in vending machine, this table represents the initial orientation sensing that given all these machine spring at front ends should be set, and can make vending machine control system automatically complete the automatic adjusting to all spring at front end initial positions.
Further, method based on above-mentioned motorized adjustment, in conjunction with automatic vending machine, be connected into the applicable cases of network, can by the mode of remote regulating, give the specific spring of specific automatic vending machine, carry out spring at front end position and point to adjusting, or, for specific goods road, for the article of possible unsuccessful release, by remote control, carry out small angle rotation (360 °/(2^n-1) angle), so that its successful shipment.
