Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present application discloses an article identification system, comprising: a photosensitive sensor module 101 and a data processing module 102 connected to the photosensitive sensor module 101.
The light-sensitive sensor modules 101 in the goods identification system can be multiple, each light-sensitive sensor module 101 comprises a plurality of light-sensitive sensors, the cabinet position of each goods corresponds to at least one light-sensitive sensor in the light-sensitive sensor module 101, and each light-sensitive sensor is used for detecting the light intensity of the position.
For example, all the photosensitive sensors corresponding to the same shelf location may form a photosensitive sensor module, or the photosensitive sensor corresponding to each shelf location may form a photosensitive sensor module, which may be specifically adjusted according to the actual application scenario of the retail store, the property of the goods, and other factors. The number of the photosensitive sensors corresponding to each cabinet position can be adjusted according to the size of the goods. For example, for small-sized goods such as lipstick, only one photosensitive sensor can be placed on the position for placing lipstick, and for large-sized goods such as schoolbag, a plurality of photosensitive sensors can be placed on the position for placing lipstick, so that whether the goods are in the cabinet state or not can be accurately identified through the plurality of photosensitive sensors.
It should be noted that the cabinet position of the goods refers to a position for placing the goods, and as for whether the device for placing the goods is a cabinet or a shelf, the implementation of the embodiment of the present application is not affected.
Alternatively, the photosensitive sensor may be a photo-electric tube, a photo-multiplier tube, a photo-resistor, a photo-triode, a fiber-optic photo-sensor, a color sensor, etc., and the difference in the types of the photosensitive sensors does not affect the implementation of the embodiment of the present application.
Alternatively, referring to FIG. 2, in a specific embodiment of the present application, the photosensors in the photosensor module may be photoresistors R, each of whichOne end of the photoresistor R receives a power supply signal VCC through the fixed resistor R1, and the other end is grounded. And the common terminal of the photoresistor R and the fixed resistor R1 outputs the optical intensity signal V1. Light intensity signal
The resistance of the photo resistor R changes with the change of the light intensity, and the larger the light intensity is, the smaller the resistance of the photo resistor R is, and the smaller the value of the light intensity signal V1 is. The light intensity at the position of the photoresistor R can be described by the light intensity signal V1. After the photoresistor R is placed at the cabinet position of the goods, when the goods are placed on the cabinet position, the light intensity is lower, so that the resistance value of the photoresistor R is larger, and the value of the light intensity signal V1 is larger. When the goods are not on the cabinet position, the light intensity is larger because of no shielding of the goods, the resistance value of the photoresistor R is smaller, and therefore the value of the light intensity signal V1 is smaller. Optionally, the photoresistor R may be connected in parallel with a capacitor C to achieve the effect of resisting alternating current interference.
The data processing module 102 can acquire the light intensity signal sent by the photosensitive sensor module 101, and for each goods, identify whether the goods are in the cabinet state or not by using the light intensity signal sent by the photosensitive sensor corresponding to the cabinet position of the goods, and then record the identification result of whether each goods are in the cabinet state or not, thereby realizing the requirement of identifying whether the goods are in the cabinet or not in the operation process of the intelligent retail store.
Optionally, referring to fig. 3, in an embodiment of the present application, the data processing module includes: a singlechip 301 connected with the photosensitive sensor module, a transceiver 302 connected with the singlechip 301, and a server 303 connected with the transceiver 302.
The specific number of the single-chip microcomputers 301 and the transceivers 302 depends on the actual situation, for example, if there are more photosensor modules, there may be more single-chip microcomputers 301. Optionally, the transceiver 302 may be a wireless protocol transceiver or a field bus protocol transceiver, and the server 303 may be a cloud server or a local server.
Specifically, the pins of the single chip microcomputer 301 are connected to the photosensor modules, each pin of the single chip microcomputer 301 receives a light intensity signal sent by each photosensor, after the single chip microcomputer 301 performs analog-to-digital conversion on the light intensity signals, the single chip microcomputer 301 can identify whether goods are in a cabinet state or not by using the light intensity signals corresponding to each goods subjected to the analog-to-digital conversion, record the identification result of whether each goods are in the cabinet state or not, and then send the recorded identification result to the server 303 through the transceiver 302.
Alternatively, the single chip microcomputer 301 may only perform analog-to-digital conversion on the light intensity signal, and then directly transmit the light intensity signal after the analog-to-digital conversion to the server 303 through the transceiver 302, so that the server 303 performs subsequent goods identification and recording. That is, the identification process of the goods and the recording of the identification result can be executed in the single chip microcomputer 301 or the server 303, and the implementation of the embodiment of the present application is not affected. Because the pins of the single chip microcomputer 301 are connected with the photosensitive sensor modules, the pins of the single chip microcomputer 301 correspond to the photosensitive sensors, the photosensitive sensors correspond to the cabinet positions of goods, and the server 303 can know the corresponding relationship between each received light intensity signal and the goods.

The single chip microcomputer 404 packages the processed light intensity signals and transmits the light intensity signals to the cloud server or the local server through the wireless transceiver by using a hypertext Transfer Protocol (HTTP), and then the server identifies whether the goods are in the cabinet state or not by using the light intensity signals sent by the photosensitive sensors corresponding to the cabinet positions of the goods and records the identification result of whether each goods is in the cabinet state or not.

The light intensity signals sent by the photosensitive sensors corresponding to the container positions of the goods are utilized by the server to identify whether the goods are in the container state, and the identification result of whether each goods is in the container state is recorded.
Optionally, referring to fig. 6, in another embodiment of the present application, pins of a single chip 601 of each photosensor S in each photosensor module are connected, a light intensity signal sent by the photosensor S is sent to the single chip 601, each single chip 601 performs analog-to-digital conversion on each light intensity signal, the processed light intensity signal is transmitted to a wireless transceiver 602 through a serial port, each wireless transceiver 602 uses a HyperText transfer protocol (HTTP) to transmit to a cloud server or a local server, the server identifies whether goods are in a cabinet state or not by using the light intensity signal sent by the photosensor corresponding to the cabinet position of each goods, records an identification result of whether each goods are in the cabinet state or not, and it should be noted that the identification of whether the goods are in the cabinet state and the recording of the identification result can be performed in the single chip 601, or may be performed in a server.
It should also be noted that there are many specific implementations of the data processing module, including but not limited to those presented in the embodiments of the present application.
Specifically, the following describes a method for identifying goods applied to a data processing module according to several embodiments.
Referring to fig. 7, the embodiment of the application discloses a goods identification method, which comprises the following steps:
s701, acquiring a light intensity signal sent by the photosensitive sensor module.
The photosensitive sensor module comprises a plurality of photosensitive sensors, the cabinet position of each goods corresponds to at least one photosensitive sensor in the photosensitive sensor module, and each photosensitive sensor is used for detecting the light intensity of the position. The implementation and principle of the photosensitive sensor module are the same as those of the photosensitive sensor module 101 in the goods identification system shown in fig. 1, and it can be referred to and will not be described herein redundantly.
Specifically, the step S701 is repeatedly executed, and whether the current goods are in the cabinet state or not is continuously identified by continuously acquiring the light intensity signal. Step S701 may be executed by acquiring the light intensity signal sent by the photosensor module in real time, or acquiring the light intensity signal according to a preset frequency, for example, acquiring the light intensity signal in a period of 0.5 second.
It should be noted that the light intensity signals obtained in step S701 are a plurality of light intensity signals corresponding to the container positions of the goods, and when step S701 is executed, in addition to the specific values of the obtained light intensity signals, the container position of the goods corresponding to each light intensity signal can be determined.
For example, the pin of the single chip in the data processing module 102 shown in fig. 1 may be connected to the photosensitive sensor in the photosensitive sensor module, and since the photosensitive sensor corresponds to the container position of the goods, the pin of the single chip corresponds to the container position of the goods. When the single chip microcomputer obtains the light intensity signal, the cabinet position corresponding to the light intensity signal can be determined by reading the pin for obtaining the light intensity signal. The light intensity signal obtained in step S701 is an electrical signal capable of reflecting the intensity of light, that is, the photosensor module converts the light signal into an electrical signal capable of being processed by the data processing module 102.
S702, aiming at each goods, identifying whether the goods are in the state of the cabinet or not by utilizing the light intensity signal sent by the photosensitive sensor corresponding to the cabinet position of the goods.
Because the light intensity signal can explain the light intensity of photosensitive sensor position, and photosensitive sensor is corresponding with the cabinet position of each goods again, photosensitive sensor arranges the cabinet position department of goods in promptly, consequently when the goods is in when the cabinet state, the light intensity that photosensitive sensor sensed is less strong, and the goods is in when not at the cabinet state, the light intensity that photosensitive sensor sensed is stronger, photosensitive sensor has changed the intensity signal into with the intensity of the light that senses, and then data processing module just can pass through the value of light intensity signal, it is in at the cabinet state to go the goods that discernment light intensity signal corresponds.
It should be noted that the light intensity signal may indicate that the light intensity at the position of the photosensor is higher when the numerical value is larger, or may indicate that the light intensity at the position of the photosensor is higher when the numerical value of the light intensity signal is smaller, and is specifically set by the structure inside the photosensor module. For example, referring to fig. 2, the value of the light intensity signal V1 decreases as the light intensity increases.
Optionally, before executing step S702, the light intensity signal corresponding to the item acquired in step S701 may be processed for each item, and then step S702 may be executed on the processed light intensity signal. For example, if the light intensity signal collected in step S701 is a voltage signal, before step S702 is executed, the analog quantity of the voltage signal may be converted into a digital quantity, that is, an analog-to-digital conversion process may be executed. Then the value of the light intensity signal converted into digital quantity is utilized to identify whether goods are in a cabinet state or not. For another example, step S702 may not be executed for the value of the light intensity signal at each time point collected in step S701, but the values of the light intensity signals within a preset time period are averaged, and the value of the light intensity signal obtained by averaging is used to identify whether the goods are currently in the cabinet state. For example, when step S701 is executed, the light intensity signals are collected every 0.5 second, and then the values of the light intensity signals in every 3 seconds, that is, the values of every 6 collected light intensity signals, are averaged to obtain the average value of the light intensity signals in every 3 seconds. And then, the average value of the light intensity signals within every 3 seconds is utilized to identify whether the goods are in the cabinet state, namely, the step S702 can be executed once every 3 seconds, so that the data processing times are reduced, and the operation efficiency is improved.
Alternatively, before step S702 is executed, normalization processing may be performed on each acquired light intensity signal. In particular, the light intensity signal shown in FIG. 2
If the values of the photoresistor R, the fixed resistor R1 and the power supply signal VCC used in each light sensor module are different, the values of the light intensity signals generated by the light sensors are different under the same light intensity, so that the value of the light intensity signal V1 can be normalized, and the values of all the light intensity signals acquired in the step S701 are unified standard values, so as to identify whether each goods is in a cabinet state. Normalized light intensity signal
Is a value less than 1. It should be noted that, if the photoresistor R, the fixed resistor R1 and the power supply signal VCC used in each of the photosensor modules are all the same, the standard for generating the value of each light intensity signal is the same, and the normalization process may not be performed.
Optionally, referring to fig. 8, in an embodiment of the present application, an implementation manner of executing step S702 includes:
s801, obtaining the state value of each goods according to the light intensity signal sent by the photosensitive sensor corresponding to the current cabinet position of each goods.
Wherein the state value of the goods is a value for reflecting whether the goods is currently in the cabinet state. The cabinet position of each goods can correspond to a plurality of light intensity signals and also can correspond to one light intensity signal. If the volume of the goods is larger, the cabinet position of the goods is larger, and therefore more photosensitive sensors are needed when the light intensity of the cabinet position of the goods is detected. If the volume of the goods is small, the cabinet position of the goods is small, and only one photosensitive sensor can be used for detecting the light intensity of the cabinet position of the goods.
If the light intensity signals corresponding to the cabinet positions of the goods are multiple, the values of the light intensity signals are processed aiming at the goods, and a state value which reflects whether the goods are in the in-place state or not is obtained. If the light intensity signal corresponding to the cabinet position of the goods is one, the value of one light intensity signal can be processed to obtain the state value of the goods, and the value of the light intensity signal can also be directly used as the state value of the goods.
Optionally, in a specific embodiment of the present application, an implementation manner of executing step S801 includes:
and for each goods, multiplying the values of the light intensity signals sent by the multiple photosensitive sensors corresponding to the goods by the corresponding weight values, and then summing to obtain the state value of the goods.
The sum of the weight values of the light intensity signals corresponding to the goods is one, and the weight value of the light intensity signal is set according to the position of the photosensitive sensor. Specifically, the set weight value may be larger for the light intensity signal sent by the photosensor at the position where it is important to determine the state of the good. A smaller weight value may be set for the light intensity signal sent by the photosensor at a location where it is not important to determine the state of the good. For example, the closer the photosensitive sensor is to the middle of the goods position, the larger the weight value can be set. When goods are in the cabinet position, if the position of placing is not too positive, the sensor at the edge of the cabinet position can be caused to feel a larger light intensity value, so that the weight value corresponding to the sensor far away from the center position is set to be smaller, and the accuracy of identifying the goods state can be improved. If the cabinet position of the goods only corresponds to one photosensitive sensor, the weight value of the light intensity signal of the photosensitive sensor is 1.
For example, referring to fig. 9, 9 light sensors S1, S2, … … and S9 are uniformly disposed at the cabinet position of a certain article. As can be seen from fig. 9, the position of the photosensor S5 is located at the center of the cabinet, so the weight value P5 corresponding to the photosensor S5 is the highest, and the distances between the photosensors S2, S4, S6, and S8 and the center of the cabinet are equal, and the corresponding weight values may be set to be equal and smaller than the weight value P5. The photosensitive sensors S1, S3, S7 and S9 are farthest from the center of the cabinet, so the set weight value can be minimized. Specifically, the weight value P5 is set to 0.4, the values of the weight values P2, P4, P6, and P8 are 0.1, the values of the weight values P1, P3, P7, and P9 are 0.05, the sum of the values P1, P2, … …, and P9 is 1, and the state value of the article is set to 0.4
S802, respectively utilizing the state value of each goods to identify whether each goods is in a cabinet state or not.
Specifically, the state value of the goods is obtained according to the value of the light intensity signal, so that the state value of the goods can indicate whether the goods exist at the current cabinet position of the goods. The state value of the goods obtained when the goods are in the cabinet state is different from the state value of the goods obtained when the goods are not in the cabinet state, so that whether the goods are in the cabinet state can be identified only by identifying whether the state value of the goods is matched with the state value of the goods when the goods are in the cabinet state.
Optionally, in a specific embodiment of the present application, the identification result of whether the goods are in the cabinet state may be divided into: in the cabinet state, the uncertain state and the non-cabinet state, a light intensity numerical range corresponding to the non-cabinet state and a light intensity numerical range corresponding to the non-confirmed state are preset. When step S802 is executed, for each article, the state value of the article is matched with the light intensity value range corresponding to the preset article state, that is, the state value of the article is respectively matched with the preset light intensity value range corresponding to the cabinet state, the preset light intensity value range corresponding to the non-cabinet state, and the preset light intensity value range corresponding to the uncertain state.
And if the state value of the goods is within the light intensity numerical range corresponding to the preset cabinet state of the goods, identifying that the goods is in the cabinet state currently. And if the state value of the goods is in the light intensity numerical range corresponding to the preset goods uncertain state, identifying that the goods are in the uncertain state currently. And if the state value of the goods is in the light intensity numerical range corresponding to the preset goods not in the cabinet state, identifying that the goods is not in the cabinet state currently.
It should be noted that there is no overlapping numerical range between the light intensity numerical range corresponding to the goods in the cabinet state, the light intensity numerical range corresponding to the uncertain state, and the light intensity numerical range corresponding to the goods not in the cabinet state.
Optionally, referring to fig. 10, in an embodiment of the present application, a method for setting a light intensity range corresponding to a preset goods state includes:
s1001, determining the value of the corresponding light intensity signal when the goods are in the cabinet state and the value of the corresponding light intensity signal when the goods are not in the cabinet state.
Specifically, the value of the light intensity signal sent by the photosensitive sensor corresponding to the position of the goods can be tested in advance when the goods are in the cabinet state. And the value of the light intensity signal sent by the photosensitive sensor corresponding to the position of the goods is tested in advance when the goods are not in the cabinet state. Because the places where the goods are located are different, the values of the light intensity signals corresponding to the goods in the cabinet state and the values of the light intensity signals corresponding to the goods in the non-cabinet state, which are measured by different goods in different places, may also be different, it is necessary to determine the values of the light intensity signals corresponding to the goods in the cabinet state and the values of the light intensity signals corresponding to the goods in the non-cabinet state in an actual application scene, and use the determined values as reference values for determining whether the goods are in the cabinet state.
It should be noted that the values of the light intensity signals corresponding to the same goods in the cabinet state measured in the same scene for multiple times are not necessarily the same values. Therefore, the values of the light intensity signals corresponding to the articles in the cabinet state, which are measured for a plurality of times, can be averaged, and the obtained average value is determined as the value of the light intensity signal corresponding to the articles in the cabinet state. Or the value range of the corresponding light intensity signal when the goods are in the cabinet state can be determined according to the values of multiple tests. The determination of the value of the corresponding light intensity signal when the goods are not in the cabinet state may be similar to the value of the corresponding light intensity signal when the goods are in the cabinet state, and will not be described herein again.
Alternatively, the value of the light intensity signal output by the photosensitive sensor module when the photosensitive sensor module is irradiated by normal light intensity can be directly tested, and the value is determined as the value of the corresponding light intensity signal when the goods are not in the cabinet state. And testing the value of the light intensity signal output by the photosensitive sensor module in the dark, and determining the value as the value of the corresponding light intensity signal when the goods are in the cabinet state.
There are many ways to determine the value of the light intensity signal corresponding to the item when in the cabinet state and the value of the light intensity signal corresponding to the item when not in the cabinet state, including but not limited to what is presented in the examples of this application.
S1002, setting a light intensity numerical range corresponding to the goods state according to the value of the light intensity signal corresponding to the goods in the cabinet state and the value of the light intensity signal corresponding to the goods out of the cabinet state.
According to the value of the corresponding light intensity signal when the goods are in the cabinet state, the corresponding light intensity numerical range when the goods are in the cabinet state can be determined. According to the value of the corresponding light intensity signal when the goods are not in the cabinet state, the light intensity numerical range corresponding to the goods when the goods are not in the cabinet state can be determined. And the values except the light intensity value range corresponding to the goods in the cabinet state and the light intensity value range corresponding to the goods not in the cabinet state constitute the light intensity value range corresponding to the goods in the uncertain state.
For example, if the value of the light intensity signal corresponding to the cargo in the cabinet state determined in step S1001 is V2, and then, considering the case where there is an error, for example, X is 30%, the light intensity value range when the cargo is in the cabinet state may be set to (V2 × (1-X), V2 × (1+ X)). similarly, if the value of the light intensity signal when the cargo is not in the cabinet state determined in step S1001 is V3, the light intensity value range corresponding to the cargo not in the cabinet state may be set to (V3 × (1-X), V3 × (1+ X)), and the light intensity value range corresponding to the indeterminate state may be set to (V2 × (1+ X), V3 × (1-X)).
And S703, recording the identification result of whether each goods is in the cabinet state.
Specifically, the current identification result of each item is recorded. The identification result may include a cabinet state, a non-cabinet state, and an uncertain state. The device for recording the identification result may be the single chip microcomputer 301 in the data processing module shown in fig. 3, or may be the server 303.
Optionally, referring to fig. 11, in an embodiment of the present application, if the identification result includes a cabinet state, a non-cabinet state, and an indeterminate state, an implementation manner of step S703 is executed, including:
s1101, aiming at each goods, if the current recognition result of the goods is in the cabinet state, adding one to the value of the corresponding in-cabinet state of the goods.
Specifically, the recognition result may be recorded by counting the detected recognition results. And setting the initial value of the in-cabinet state, the initial value of the uncertain state and the initial value of the out-of-cabinet state corresponding to the goods to be zero for each goods. Then, when it is detected that the current identification result of the goods is in the cabinet state, the value of the in-cabinet state corresponding to the goods is added by one, that is, the number of times of identifying the in-cabinet state in the step S702 is counted.
Alternatively, it may be set that the first time the goods are detected to be in the cabinet state, that is, the value in the cabinet state is changed from zero to the beginning, and then the recording of the identification result is performed. If the article is detected to be in the cabinet state for the first time, the article is indicated to be in the state of being sold in the retail store, and therefore statistical recording can be started. In the operation stage of the retail store, if the value of the in-cabinet state corresponding to the goods counted by the goods is larger, the longer the time that the goods are in the in-cabinet state is shown, and further the condition that the goods are low in popularity and are not taken down by the customer is shown.
And S1102, if the current identification result of the goods is in the uncertain state, adding one to the value of the uncertain state corresponding to the goods.
Alternatively, the item identification system shown in FIG. 1 may be adjusted based on the value of the indeterminate state corresponding to the item. If the value of the corresponding uncertain state of the goods is larger, the accuracy of goods identification is lower, whether the goods are in the state or not can not be accurately identified, and then the photosensitive sensor module, the data processing module and the like need to be adjusted.
And S1103, if the current identification result of the goods is in the state of not being stored in the cabinet, adding one to the value of the state of not being stored in the cabinet corresponding to the goods.
The initial value of the out-of-cabinet state corresponding to the goods is zero. When the current identification result is detected to be the out-of-cabinet state, the value of the out-of-cabinet state corresponding to the goods is added by one, that is, the number of times that the out-of-cabinet state is identified in the step S702 is counted. The larger the value of the out-of-cabinet state corresponding to the recorded goods is, the more popular the goods are.

The preset time period may be set to any time period such as 1 month or 1 day. For example, if the preset time period is set to 1 month, the exposure rate of each item in 1 month can be counted, and then the most popular item in the 1 month can be obtained, and the retail store can adjust the goods input according to the popularity of the items.
It should be noted that the recorded identification result of whether each item is in the cabinet state may be applied to other scenarios besides calculating the exposure rate of the item.
