It should be noted that the above-mentioned articles may be various goods for sale, for example: drinks, lunch boxes, etc., and may be partitions for isolating goods disposed in the cargo duct 120.
It should be further noted that when there is an article in the cargo way 120, the article may block the light receiver 202 at the corresponding position from receiving the light emitted by the corresponding light generator 201, the light receiver 202 at the corresponding position outputs a first detection signal, when there is no article in the cargo way 120, each light receiver 202 can receive the light emitted by the corresponding light generator 201, and each light receiver 202 outputs a second detection signal.
A plurality of light generators 201 in the goods way 120 of automatic vending machine 010 of this embodiment are divided into two at least detection assembly by controlling means 300, and a plurality of light generators 201 in every detection assembly are not adjacent each other, because two detection assembly that controlling means 300 control includes two adjacent light generators 201 are luminous simultaneously, therefore, adjacent light generator 201 can not be luminous simultaneously in the goods way 120, luminous light generator 201's interval is great simultaneously, avoid light receiver 202 to receive rather than the luminous interference of the adjacent light generator 201 of relative light generator 201, thereby whether the accuracy of goods has in the goods way 120 is detected in light generator 201 and light receiver 202 mutually supporting has been improved.

For example: totally 64 light generators 201 are arranged in one cargo channel 120, the 64 light generators 201 are sequentially divided into 8 sections by a control device 300 along the arrangement direction of the objects, wherein each section comprises the 8 light generators 201 which are sequentially arranged, the light generators 201 in each section are sequentially numbered as 1-8 numbers by the control device 300 along the arrangement direction of the objects, the light generators 201 numbered as 1 number in each section are divided into a first detection component by the control device 300, the light generators 201 numbered as 2 numbers in each section are divided into a second detection component, the light generators 201 numbered as 3 numbers in each section are divided into a third detection component, the light generators 201 numbered as 4 numbers in each section are divided into a fourth detection component, the light generators 201 numbered as 5 numbers in each section are divided into a fifth detection component, the light generators 201 numbered as 6 numbers in each section are divided into a sixth detection component, the light generator 201 numbered 7 in each segment is divided into the seventh detection assembly, and the light generator 201 numbered 8 in each segment is divided into the eighth detection assembly. It should be noted that, in different specific embodiments, the number of the light generators 201 arranged in the cargo way 120, the number of the divided detection assemblies, the number of the light generators 201 in each detection assembly, and the like are not specifically limited; the number of the plurality of light generators 201 provided in each of the channels 120 in the vending machine 010 of the same embodiment may be the same or different; the number of light generators 201 in each detection assembly in the same lane 120 may be the same or different.
Further, the control device 300 is configured to sequentially control the plurality of light generators 201 in each detection assembly to emit light simultaneously, and when the plurality of light generators 201 in each detection assembly emit light simultaneously, read the output value of the light receiver 202 corresponding to each light generator 201 of the detection assembly that emits light; specifically, the control device 300 controls the multiple light generators 201 of one detection assembly to emit light simultaneously, reads the output value of the light receiver 202 corresponding to each light generator 201 in the light emitting detection assembly, after reading the output value, the control device 300 controls each light generator 201 in the light emitting detection assembly to be turned off, controls the multiple light generators 201 in the next detection assembly to emit light simultaneously, reads the output value of the light receiver 202 corresponding to each light generator 201 in the light emitting detection assembly, and circulates the process until the output value of each light receiver 202 of the last detection assembly in the cargo way 120 is read, and controls the multiple light generators 201 of the first detection assembly in the cargo way 120 to emit light simultaneously. For example: after the detection assemblies are divided according to the method, the light generators 201 in the first detection assembly, the second detection assembly, the third detection assembly, the fourth detection assembly, the fifth detection assembly, the sixth detection assembly, the seventh detection assembly and the eighth detection assembly are controlled to emit light in sequence, and the output value of each light receiver 202 in the corresponding detection assembly is read; because a plurality of light generators 201 in a detection subassembly are not adjacent to each other, so, control a detection subassembly's light generator 201 through controlling means 300 at every turn and give out light, can make adjacent light generator 201 can not give out light simultaneously to avoid optical receiver 202 to receive rather than the interference of another light generator 201 that optical generator 201 is adjacent, whether improved the accuracy that detects article in the goods way 120.
It should be noted that, in other embodiments, after the detection assemblies are divided according to the above method, at least two detection assemblies with non-adjacent numbers may be simultaneously controlled to simultaneously emit light and read the output value of the corresponding optical receiver 202, for example: and meanwhile, the first detection assembly and the third detection assembly are controlled to emit light and read the output value of the corresponding light receiver 202, the first detection assembly and the third detection assembly are controlled not to emit light, the second detection assembly and the fourth detection assembly are controlled to emit light and read the output value of the corresponding light receiver 202, the second detection assembly and the fourth detection assembly are controlled not to emit light, the fifth detection assembly and the seventh detection assembly are controlled to emit light and read the output value of the corresponding light receiver 202, the fifth detection assembly and the seventh detection assembly are controlled not to emit light, and the sixth detection assembly and the eighth detection assembly are controlled to emit light and read the corresponding output value. In this way, the detection time of all the light receivers 202 can be shortened to improve the detection efficiency, and the number of the detection components which emit light simultaneously can be set appropriately, so that the operation efficiency of the control device 300 and the overall power consumption of the vending machine 010 can meet the set requirements.
Preferably, the control device 300 of the present embodiment controls the light generators 201 in one detection assembly to emit light, and specifically includes: the control device 300 controls a plurality of light generators 201 of one detection assembly to emit light simultaneously; the control device 300 controls the plurality of light generators 201 of one detection assembly not to emit light, and specifically includes: the control device 300 controls a plurality of light generators 201 of one detection assembly to be turned off simultaneously; thus, the detection time of all the light receivers 202 can be shortened to improve the detection efficiency.
Further, the control device 300 of the present embodiment is configured to obtain the width of the cargo way 120, determine the minimum distance between the light generators 201 of each detection assembly according to the width of the cargo way 120, and divide the plurality of light generators 201 and the plurality of light receivers 202 in the cargo way 120 into at least two detection assemblies according to the minimum distance between the light generators 201, where the minimum distance between the light generators 201 is the distance between two light generators 201 closest to each other in the plurality of light generators 201 of the detection assemblies, and the width of the cargo way 120 is: the spacing between the first baffle 122 and the second baffle 123 in the lane 120; in this way, the minimum distance between the light generators 201 in the detection assemblies in different cargo ways 120 can be determined to be different values for the cargo ways 120 with different widths, so that the minimum distance between the light generators 201 is adapted to the width of the cargo ways 120, and the detection accuracy is further improved.
Preferably, the width of the cargo way 120 is in a positive linear relationship with the minimum distance between the light generators 201 of each detection assembly, that is, the larger the width of the cargo way 120 is, the larger the distance between the two light generators 201 with the minimum distance between the middle of each detection assembly is, so that light cross-talk can be prevented when detecting whether there is a product in the cargo way 120, and the detection accuracy can be improved; it should be noted that the width of the cargo way 120 may also be in a positive linear relationship with the number of light generators 201 of other detection assemblies disposed between the two light generators 201 in each detection assembly, that is, the larger the width of the cargo way 120 is, the larger the number of light generators 201 of other detection assemblies disposed between the two light generators 201 in each detection assembly is, for example: the total number of light generators 201 in one light tunnel 120 is 64, when the width of the light tunnel 120 is 15cm, the total number of light generators 201 of other detection assemblies disposed between two light generators 201 in one detection assembly is 7, and when the width of the light tunnel 120 is 10cm, the total number of light generators 201 of other detection assemblies disposed between two light generators 201 in one detection assembly is 3.
Further, the control device 300 of the present embodiment is configured to, after the control device 300 obtains the width of each cargo channel 120, sequentially divide the plurality of light generators 201 in the cargo channel 120 into a plurality of sections along the arrangement direction according to the width, sequentially number the plurality of light generators 201 in each section according to the arrangement order, and divide the light generators 201 with the same number in each section into one detection assembly. Since the width of the cargo channel 120 is in a positive linear relationship with the minimum distance between the light generators 201 of each detection assembly, it is easy to know that when the detection assemblies are divided according to the method, the larger the width of the cargo channel 120 is, the fewer the number of segments divided in the cargo channel 120 should be, so that the spacing distance between two adjacent segments, that is, the distance between two light generators 201 closest to each other in the same detection assembly is, the larger the distance between the two light generators 201. For example: when the width of the cargo channel 120 is 15cm, the control device 300 divides the 64 light generators 201 into 8 segments, so that the distance between two light generators 201 closest to each detection assembly is large; when the width of the cargo channel 120 is 10cm, the control device 300 divides the 64 light generators 201 into 16 segments such that the interval between two light generators 201 closest to each detection assembly is small.
Further, referring to fig. 5, the vending machine 010 of the embodiment further includes a memory 310, the memory 310 is electrically connected to the control device 300, the memory 310 is configured to store the width of each of the channels 120, and the control device 300 is configured to read the width of each of the channels 120 from the memory 310; by reading the width of each lane 120 stored in the memory 310 in advance, the control device 300 can more efficiently acquire the width of the lane 120.
Fig. 6 is a block diagram showing a second vending machine 010 according to an embodiment of the present invention.
