Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and examples.
Referring to fig. 1, a schematic structural diagram of an embodiment of a device for positioning wine in a wine cabinet according to the present invention is shown.
As shown in figure 1, the wine cabinet comprises a wine rack 1, and the wine rack 1 is provided with a plurality of wine positions, such as wine positions from No. 1 to No. sixty percent, shown in figure 1. In order to determine whether wine is placed at the wine position on the wine rack 1, the specific structure of the device for positioning wine provided by the embodiment is as follows:
the wine rack 1 is provided with a first reflection assembly 11, a second reflection assembly 12, an ultrasonic generator 14 and an ultrasonic receiver 15, and the ultrasonic transmitter 14 and the ultrasonic receiver 15 are also respectively connected with a wine positioning processing unit 16. Wherein, the first reflection assembly 11 and the second reflection assembly 12 are respectively arranged at two ends of the wine rack 1 along the wine placing direction on the wine rack. Specifically, as shown in fig. 1, the wine levels on the wine rack 1 are sequentially arranged in the left-right direction of the wine rack 1, the wine placement direction is longitudinal for each wine level, i.e., the up-down direction in fig. 1, the first reflecting member 11 is formed at the lower end of the wine rack 1, and the second reflecting member 12 is formed at the upper end of the wine rack 1. Furthermore, the first reflecting assembly 11 comprises a plurality of reflecting elements (indicated by the inclined lines in the figure), one or more for each wine level. Similarly, the second reflective arrangement 12 includes a plurality of reflective elements (shown as slanted lines) one or more for each level. An ultrasonic generator 14 is provided on the wine rack 1 adjacent the first reflective assembly 11. An ultrasonic receiver 15 is provided on the wine rack 1 adjacent the second reflective arrangement 12.
As a preferred embodiment, the reflecting surfaces of the plurality of reflecting elements in the first reflecting assembly 11 and the plurality of reflecting elements in the second reflecting assembly 12 are each disposed in an inclined direction at an angle of 45 ° to the wine placing direction, and the inclined directions in the two reflecting assemblies are opposite. The ultrasonic waves emitted from the ultrasonic transmitting transducer in the ultrasonic generator 14 are controlled to be horizontally transmitted to the left at an incident angle of 45 ° to the plurality of reflecting elements in the first reflecting assembly 11. While being transmitted to the left, the ultrasonic waves are reflected upward by the plurality of reflecting elements in the first reflecting assembly 11 at a reflection angle of 45 °, pass through the wine levels in a vertically upward direction, and then are reflected to the plurality of reflecting elements in the second reflecting assembly 12 at an incidence angle of 45 °. Finally, the ultrasonic waves after passing through the wine level, which are reflected by the plurality of reflection elements in the second reflection assembly 12 and are reflected by the plurality of reflection elements in the first reflection assembly 11, are received by the ultrasonic receiver 15 at a reflection angle of 45 °, i.e., in a horizontal left direction.
In the above transmission process of the ultrasonic wave, if the wine 13 is placed on the wine level, the energy attenuation is large due to the blocking of the wine 13, and the power of the ultrasonic wave received by the ultrasonic receiver 15 is obviously changed compared with the case of not placing the wine. Then, the wine positioning processing unit 16 can determine whether wine is placed on the wine level of the wine rack 1 by analyzing the received ultrasonic waves received by the ultrasonic receiver 15. In combination with other means, the wine level information of the wine when the wine is placed can be further determined, namely the position information of the wine level of the wine on which wine level on the wine rack 1 is located. For a specific judgment method, reference is made to the following detailed description of the method embodiment.
It should be understood that the arrangement of the reflective elements in the first reflective assembly 11 and the second reflective assembly 12 is not limited to the above-mentioned 45 ° inclination angle. As long as the relative positions of the first reflecting component 11, the second reflecting component 12, the ultrasonic generator 14 and the ultrasonic receiver 15 are configured, the ultrasonic wave emitted by the ultrasonic generator 14 can be transmitted to the first reflecting component 11, the first reflecting component 11 transmits the ultrasonic wave to the second reflecting component 12 along the wine placing direction on the wine level, and the second reflecting component 12 reflects the ultrasonic wave transmitted along the wine placing direction on the wine level into the ultrasonic receiver 15.
The above embodiment is a structural schematic diagram of the device for realizing wine positioning by taking one layer of wine rack 1 as an example, and if a plurality of layers of wine racks are provided, the structure of the rest layers of wine racks can be configured by referring to the structure of the wine rack 1 in fig. 1.
In other embodiments, the apparatus for positioning wine in a wine cabinet may further include:
the door body switch detection unit is used for detecting and judging whether the wine cabinet door body is opened or not; and
the wireless radio frequency module is arranged at a designated position and used for acquiring wine information of wine in a designated scanning area; the designated scanning area is the area away from the wine level on the wine rack in the wine cabinet.
The specific operation of the device with such a structure is also referred to in the following detailed description of the method embodiments.
Referring to fig. 2, a flow chart of an embodiment of a method for positioning wine in a wine cabinet according to the present invention is shown, and specifically, an embodiment of a method for positioning wine based on the apparatus for positioning wine in a wine cabinet of fig. 1 is shown.
As illustrated in fig. 2, in conjunction with the implementation apparatus of fig. 1, the method for implementing wine positioning of this embodiment includes the following processes:
step 21: and the ultrasonic generators which correspond to the wine racks one by one are controlled to emit set ultrasonic waves, and the set ultrasonic waves are transmitted to the first reflection assemblies which correspond to the ultrasonic generators on the wine racks.
Because the transmission distance of the ultrasonic wave is related to the transmitting power of the ultrasonic wave, the ultrasonic wave is required to be controlled to be set, and the ultrasonic wave is required to be transmitted by the ultrasonic generator on the wine rack in order to ensure that the ultrasonic wave can pass through each wine position on the wine rack.
In particular, a preferred but not limiting implementation is: and determining the transmitting power of the ultrasonic generator according to the total width of all wine positions on the wine rack, and sending out the ultrasonic waves determined by the transmitting power as the set ultrasonic waves of the ultrasonic generator. The set ultrasonic wave is transmitted to the first reflection assembly on the wine rack after being emitted.
Step 22: and acquiring the received ultrasonic waves output by an ultrasonic receiver matched with the ultrasonic generator.
As described in the embodiment of the implementation device in FIG. 1, the received ultrasonic waves are ultrasonic waves which are reflected by the ultrasonic generator to the wine level of the wine rack through the first reflecting component, transmitted to the second reflecting component along the wine placing direction of the wine level and reflected by the second reflecting component to the ultrasonic receiver.
Step 23: whether wine is placed on the wine rack and the wine position information of the wine when the wine is placed are determined according to the received ultrasonic waves, and the wine on the wine rack is positioned.
As described above, when the ultrasonic waves pass through the wine level, the wine or wine not placed on the wine level will have a significant influence on the power of the received ultrasonic waves. Whether wine is placed on the wine rack can be judged by analyzing and receiving the ultrasonic waves.
For example, as shown in fig. 1, in the case where a wine is placed at the third wine position, a waveform diagram of the received ultrasonic wave is shown in fig. 3, and in fig. 3, the abscissa is time and the ordinate is power. In waveform a, there is a significant notch B with decreasing frequency (graph). The existence of the notch B is caused by attenuation of ultrasonic energy caused by the existence of wine at the No. three wine position.
Particularly, confirm whether to place the wine on the wine frame and the wine position information of wine when placing the wine according to receiving the ultrasonic wave, realize right wine location on the wine frame specifically includes:
judging whether a waveform signal with power smaller than the set receiving power exists in the received ultrasonic waves; the set received power is determined according to the power of the set ultrasonic wave emitted by the ultrasonic generator. Generally, in addition to the power reduction of the ultrasonic wave caused by the wine at the wine level, the power of the ultrasonic wave generated by the ultrasonic wave generator is slightly lost after the set ultrasonic wave is changed into the receiving ultrasonic wave output by the ultrasonic wave receiver through the set transmission path, and the power loss is very small compared with the power loss caused by the wine, so that the power loss can be ignored or estimated. By determining an appropriate set reception power from the power of the set ultrasonic wave, it is possible to reduce the power due to the presence of alcohol in the case where a waveform signal having a power smaller than the set reception power is present in the received ultrasonic wave. Therefore, whether wine is placed on the wine rack can be judged according to whether a waveform signal with power smaller than the set receiving power exists in the received ultrasonic waves.
If so, judging that the wine is placed on the wine rack. Then, the wine level information of the wine is further judged. Specifically, first, the generation time of a waveform signal smaller than the set reception power is acquired.
And then, determining wine level information corresponding to the generation time of the waveform signal smaller than the set receiving power according to the corresponding relation between the generation time of the received ultrasonic waveform signal and the wine level information, wherein the wine level information is the wine level information of wine when wine is placed on the wine rack.
As the ultrasonic wave transmission characteristics determine, the generation time of the received ultrasonic wave waveform signal received by the ultrasonic receiver corresponds to the transmission distance, and thus, for the configuration in fig. 1, the ultrasonic wave passing through the rightmost alcohol position is the waveform with the earliest generation time in the received ultrasonic wave, and the ultrasonic wave passing through the leftmost alcohol position is the waveform with the latest generation time in the received ultrasonic wave. In the received ultrasonic waveform a of fig. 3, the received ultrasonic wave passing through the wine position of # i corresponding to the abscissa reception time less than T1, the received ultrasonic wave passing through the wine position of # i corresponding to the abscissa reception times between T1 and T2, the received ultrasonic wave passing through the wine position of # iii corresponding to the abscissa reception times between T2 and T3, the received ultrasonic wave passing through the wine position of # iv corresponding to the abscissa reception times between T3 and T4, the received ultrasonic wave passing through the wine position of # v corresponding to the abscissa reception times between T4 and T5, and the received ultrasonic wave passing through the wine position of # c corresponding to the abscissa reception times between T5 and T6 can be determined by combining the left-right width, the front-rear depth and the speed of the ultrasonic wave, thereby forming a corresponding relationship between the generation time of the received ultrasonic waveform signal and the information of the wine position. By analyzing the waveform of fig. 3, it can be known that the generation time of the waveform notch B with the power less than the set power is between T2 and T3, and it can be known from the corresponding relationship between the generation time of the received ultrasonic waveform signal and the wine level information that the wine level information corresponding to the generation time is No. three wine levels, so that it can be determined that the wine is placed at the No. three wine levels of the wine rack. That is, the wine level information of the wine is the third wine level on the wine rack.
In addition to the above-mentioned determination of the wine level information of the wine by using the relationship between the generation time of the received ultrasonic waveform signal and the wine level information, those skilled in the art can also consider to use other technical means based on the positioning technology using ultrasonic waves provided in this embodiment, and this embodiment is not limited to this.
The above embodiment is an example of a wine rack, and how to judge whether wine is placed on the wine rack and the wine level information of the wine is described. To the gradevin of specific multilayer wine frame, can also be through confirming the positional information who receives the wine frame that the ultrasonic wave corresponds, according to the positional information of wine frame and the wine position information of wine when placing the wine, realize the wine location on all wine frames in the gradevin. And the determination of the position information of the wine rack corresponding to the received ultrasonic waves can be realized by adopting various different modes. Such as by hardware. Specifically, the ultrasonic receiver corresponding to each layer of wine rack is connected to the wine positioning processing unit (for example, MCU is used as the wine positioning processing unit) through a designated hardware interface. Then, by presetting the corresponding relation between the designated hardware interface and the position of the wine rack, and judging which hardware interface transmits the received ultrasonic wave, the position information of the wine rack corresponding to the received ultrasonic wave can be judged. Alternatively, it may be implemented by software. Specifically, the corresponding relation between the ultrasonic waveform identifier and the wine rack position is preset, and when the ultrasonic generator sends set ultrasonic waves, the set ultrasonic waves carry identifiers corresponding to the wine rack positions one by one, and the identifiers can be reflected in the received ultrasonic waves. Then, by analyzing the mark in the received ultrasonic wave and combining the corresponding relation between the ultrasonic wave shape mark and the wine rack position, the position information of the wine rack corresponding to the received ultrasonic wave can be judged.
In other embodiments, whether the wine on the wine rack changes or not can be judged according to the wine level information of the wine when the wine is placed on the wine rack twice before and after, and whether the wine is placed or taken away when the wine changes is judged.
Specifically, the currently determined wine level information of the wine when the wine rack is placed with the wine is compared with the wine level information of the wine when the wine rack is placed with the wine at the previous time, and the change of the wine on the wine rack is judged according to the comparison result. The method specifically comprises the following steps:
and if the comparison result is that the wine level information of the wine when the wine is placed on the currently determined wine rack is not changed compared with the wine level information of the wine when the wine is placed on the previous wine rack, judging that the wine on the wine rack is not changed.
And if the comparison result is that the wine level information of the wine when the wine is placed on the currently determined wine rack is compared with the wine level information of the wine when the wine is placed on the previous wine rack, new wine level information is added, the wine rack is judged to be newly placed with the wine, and the wine level information of the newly placed wine is the new wine level information.
And if the comparison result is that the wine level information of the wine when the wine is placed on the currently determined wine rack is lack of the wine level information compared with the wine level information of the wine when the wine is placed on the previous wine rack, judging that the wine is newly taken away from the wine rack, and determining that the wine level information of the newly taken wine is the lack of the wine level information.
In other embodiments, the association of the wine level information and the wine information of the wine in the wine cabinet can also be realized.
As a preferred embodiment, the association between the wine level information and the wine information of the wine in the wine cabinet is realized, which specifically includes:
firstly, acquiring the wine information of the wine in the designated scanning area by using the wireless radio frequency module. Wherein the designated scanning area is an area away from a wine level on a wine rack in the wine cabinet. That is, the radio frequency module is only used for scanning the wine information of the wine in the designated scanning area of the wine level on the wine rack in the wine cabinet. Therefore, a wireless radio frequency module is not required to be arranged on each wine position, and the problem of low identification rate caused by mutual interference among a plurality of wireless radio frequency modules is avoided. In addition, the wireless radio frequency module is used for scanning a fixed scanning area away from the wine position, so that the wireless radio frequency module is convenient to hide and arrange, and the problem of low recognition rate caused by external interference when the wireless radio frequency module is exposed is avoided. For example, the designated scanning area is an area between the outer edge of the wine rack and the door body of the wine cabinet, and the area can be covered by arranging the radio frequency module on the door body. The wireless radio frequency module is arranged on the door body, so that the wireless radio frequency module can be hidden in the door body, for example, the wireless radio frequency module is arranged in a foaming layer of the door body, the wine can be scanned in the scanning range, the wine information can be acquired, and the influence of external interference on the identification rate is avoided. In addition, because the scanning area of the radio frequency module is an area away from the wine position, the wine information scanning in the process of putting in or taking out the wine can be realized instead of scanning the static wine, and the problem that the identification rate is influenced by static interference is further avoided. By reasonably selecting the scanning area, the area is a must-pass area for putting in or taking out wine, so that the wine information of each bottle of wine can be ensured to be scanned, and the completeness and the accuracy of positioning are ensured. Preferably, the designated scanning area is an area between the outer edge of the wine rack and the wine cabinet door body. The process of acquiring the wine information of the wine by using the wireless radio frequency module can be realized by adopting the prior art. In brief, a radio frequency device including a radio frequency antenna and a radio frequency reader-writer is used for scanning a radio frequency tag on wine to acquire wine information stored in the radio frequency tag.
And then, if the newly placed wine on the wine rack is judged to occur within the set time after the wine information of the wine in the specified scanning area is acquired, the acquired wine information of the wine in the specified scanning area is judged to be the wine information of the newly placed wine, and the wine information of the newly placed wine and the wine position information of the newly placed wine are correspondingly matched to form the corresponding relation between the wine information in the wine cabinet and the wine position information. The set time is a preset time, generally a motion time of taking or putting wine, and is used for limiting the time of acquiring wine information and judging the continuity of the time of newly putting wine on the wine rack. After the wine information is read from the designated scanning area, the action of putting in or taking out the wine is indicated. Subsequently, the newly placed wine on the wine rack is judged, so that the newly placed wine can be determined as the wine just placed.
And if the newly taken wine on the wine rack is judged to occur within the set time after the wine information of the wine in the specified scanning area is acquired, the acquired wine information of the wine in the specified scanning area is judged to be the wine information of the newly taken wine, and the wine information of the newly taken wine and the wine position information of the newly taken wine are deleted from the corresponding relation between the wine information and the wine position information in the wine cabinet. The selection and meaning of the setting time are the same as above. After the wine information is read from the designated scanning area, the action of putting in or taking out the wine is indicated. And then, judging that the wine is taken away from the wine rack, so that the wine taken away newly can be determined as the wine which is just taken away. Furthermore, since the corresponding relationship between the wine information and the wine level information is already stored when the wine is placed in the wine cabinet, after the wine is taken out, the wine information and the wine level information of the wine taken out need to be deleted from the corresponding relationship between the wine information and the wine level information in the wine cabinet, and the stored corresponding relationship is the wine information of the wine actually stored in the wine cabinet and the wine level information of the wine position where the wine is located.
Besides the adoption of the mode to realize the correspondence between the wine information and the wine level information of the wine in the wine cabinet, the wine information can be acquired by adopting other modes in the prior art to realize the correspondence with the wine level information. For example, the wine information is acquired by arranging a radio frequency scanning module or a bar code scanning module at each wine position, and the wine information is combined with the wine position information of the known wine position.
In other embodiments, in order to reduce adverse factors caused by unnecessary component actions, as a preferred embodiment, whether a wine cabinet door body is opened or not is judged firstly; when the door body of the wine cabinet is judged to be opened, the ultrasonic generator and the ultrasonic receiver are started again, and the ultrasonic generators corresponding to the wine racks one to one are controlled to send out set ultrasonic waves. And whether the wine cabinet door body is opened or not can be judged by arranging the sensor module on the door body or the inner container near the cabinet opening.
In the method and apparatus for positioning wine in a wine cabinet provided in the foregoing embodiments, the first reflecting module and the second reflecting module are respectively disposed at two ends of the wine rack along the wine placing direction, the ultrasonic generator corresponding to the first reflecting module and the ultrasonic receiver corresponding to the second reflecting module are disposed for the wine rack, the ultrasonic generator emits the set ultrasonic wave, the set ultrasonic wave is reflected to the wine level of the wine rack by the first reflecting module and transmitted to the second reflecting module along the wine placing direction, and finally transmitted to the ultrasonic receiver by the second reflecting module, and in the ultrasonic propagation path, the wine or no wine is placed on the wine level, which may significantly affect the power of the received ultrasonic wave received by the ultrasonic receiver, and the wine level information on each wine rack corresponds to the receiving time of the received ultrasonic wave, so that, through the analysis of the received ultrasonic waves received by the ultrasonic receiver, whether wine is placed on the wine rack or not and the wine level information of the wine when the wine is placed can be determined, so that the positioning of the wine on the wine rack is realized. The device provided by the invention has the advantages of simple structure, easiness in realization, difficulty in interference and high identification accuracy, so that the accuracy of wine positioning is improved.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
