  However, the above-described conventional technology still has a problem that it is not possible to prevent quality deterioration during the distribution process.

  In other words, the management system described above merely provides support for appropriately maintaining the environment in which the crop is stored, and does not consider that the freshness of the crop is impaired during the distribution process. An example is the effect of ethylene gas, a type of plant hormone released by agricultural crops. Plants still breathe after they are harvested, releasing ethylene gas in the process. Ethylene gas has the effect of promoting the growth of certain plants. For example, if a crop whose freshness is likely to be reduced by ethylene gas is loaded near a crop that produces ethylene gas, the former crop will be affected by the ethylene gas produced by the latter crop. .

  Here, the case where the freshness of other crops is reduced by the ethylene gas produced by the crops has been described, but the quality in the distribution process is also the same when the odorous components produced by the products adhere to other products. The problem of degradation occurs.

  The disclosed technique has been made in view of the above, and an object thereof is to provide a product determination method and a product determination device that can prevent quality degradation in a distribution process.

  In the product determination method disclosed in the present application, a computer executes a process of identifying a plurality of articles placed in a predetermined area. Further, the computer determines the output degree of the first article and the influence degree of the second article from the storage unit according to the identification result of the first article and the second article among the plurality of articles. Execute the acquisition process. The storage unit stores, for each article, a gas production level produced by the article and an influence level of the article affected by the gas. Further, the computer determines whether or not the first article and the second article are stacked within a range determined by the production degree of the first article and the influence degree of the second article. Execute. Further, the computer executes a process of controlling to perform notification when it is determined that the computer is within the range.

  According to one aspect of the product determination method disclosed in the present application, there is an effect that it is possible to prevent quality degradation during the distribution process.

  Embodiments of the product judgment method and product judgment device disclosed in the present application will be described below in detail with reference to the drawings. Note that this embodiment does not limit the disclosed technology. Each embodiment can be appropriately combined within a range in which processing contents are not contradictory.

[System configuration]
First, the system configuration of the product determination system according to the present embodiment will be described. FIG. 1 is a diagram illustrating a configuration of a product determination system according to the first embodiment. The product determination system shown in FIG. 1 accommodates a camera 30, a portable terminal 50, and a product determination server 10. In the example of FIG. 1, whether or not the product 5 has been stacked by the worker 5 from the image obtained by the product determination server 10 in the data center 1 in which the loading platform of the vehicle 3 is captured by the camera 30. Assume a case of determining whether or not.

  The camera 30 and the portable terminal 50 are connected to the product determination server 10 via the network 7 so that they can communicate with each other. Examples of the network 7 include communication networks such as the Internet (Internet), LAN (Local Area Network), and VPN (Virtual Private Network). The network 7 is not limited to wired communication, and may be wireless communication. In the example of FIG. 1, the case where the camera 30 and the portable terminal 50 are accommodated one by one is illustrated, but it is sufficient that at least one set of the camera 30 and the portable terminal 50 is accommodated. 30 and the portable terminal 50 can be applied.

  Among these, the camera 30 is an imaging device that captures an image. An example of such a camera 30 is an imaging device using a charge coupled device (CCD), a complementary metal oxide semiconductor (CMOS), or the like.

  Furthermore, the camera 30 functions as a network camera, and transmits an image obtained by capturing the loading platform of the vehicle 3 to the product determination server 10. As an example of installation of such a camera 30, the operator 5 can take an image of the operation of loading a load on the loading platform of the vehicle 3, loading it in the loading platform, and loading it from the loading platform to the outside of the vehicle. It is installed at a position where you can look down on the loading platform. Note that a stereo camera may be employed as the camera 30 or a wide-angle lens may be used as the camera 30 in order to obtain a loading platform image that facilitates image analysis of the position where the load is placed. The orientation may be horizontally rotated or the angle of elevation can be adjusted.

  Here, in the example shown in FIG. 1, assuming that the agricultural products packed as luggage are loaded on the loading platform of the vehicle 3 and transported, the same kind of agricultural products is packed in one luggage as follows. Give an explanation. In the following, an image of the loading platform of the vehicle 3 captured by the camera 30 is expressed as “loading platform image”, and a load loaded on the loading platform of the vehicle 3 may be expressed as “loading”. .

  The portable terminal 50 is a terminal device that is carried by the worker 5. As one mode of the portable terminal 50, a portable terminal for business use that is lent or supplied to the worker 5 by a distributor for managing the package, for example, receiving, collecting, loading, or checking the delivery can be adopted. As another aspect, a mobile terminal such as a mobile phone, a PHS (Personal Handyphone System), or a PDA (Personal Digital Assistant) may be employed. In the example of FIG. 1, the case where a business-use portable terminal, a mobile terminal, or the like is employed as the portable terminal 50 is illustrated. However, any device that can transmit information to the worker 5 may be used, and the portable terminal 50 is not necessarily a portable terminal. There is no need. For example, an in-vehicle terminal, an in-vehicle lamp or a speaker may be employed.

  The product determination server 10 is a computer on a network that provides a service for determining whether or not the product of the cargo loaded on the loading platform of the vehicle 3 may lead to quality degradation. As an example, the product determination server 10 acquires a loading platform image in which the loading platform of the vehicle 3 is imaged by the camera 30 mounted on the loading platform of the vehicle 3. When such a cargo bed image is acquired over time, an image showing a state of being transported by the vehicle 3 is included, and a state in which loading work, reloading work, and loading work are performed by the worker 5 is shown. Contains images. The loading determination server 10 uses the loading platform image in which the loading operation or the reloading operation is reflected in the loading platform image, or the loading is performed in a state where there is a risk that the freshness of the crops may be reduced by the worker 5. It is determined whether or not it has been corrected. Then, when the load is loaded or reloaded by the operator 5 in a state where the freshness of the crop is likely to be lowered, the product determination server 10 performs notification by display output or voice output to the portable terminal 50. Let

  Here, the combination determination server 10 according to the present embodiment identifies the crops packed in the luggage loaded on the loading platform of the vehicle 3. Then, the stack determination server 10 according to the present embodiment stores the degree of ethylene gas produced by the package packed with the crop for each crop and the degree of influence that the package packed with the crop is affected by the ethylene gas. Refer to the storage unit. Subsequently, according to the identification result of the first package and the second package, the product determination server 10 according to the present embodiment determines the first package output level and the influence of the second package from the previous storage unit. Get the degree. Furthermore, the product determination server 10 according to the present embodiment determines whether or not the first package and the second package have been loaded within a range determined by the production degree of the first package and the influence level of the second package. Determine. In addition, the product determination server 10 according to the present embodiment controls to execute notification when it is determined that the first package and the second package are within the previous range.

  As described above, the stack determination server 10 according to the present embodiment identifies the crops packed in the luggage loaded on the loading platform of the vehicle 3, and the freshness is reduced due to the packing of the crops that produce ethylene gas and the ethylene gas. Notification is executed when a load packed with agricultural products to be stacked is stacked nearby.

  At this time, for example, when a warning is given to the operator 5 to load the packages apart, the packages in which crops that produce ethylene gas are packed on the loading platform of the vehicle 3 or packages whose freshness decreases due to ethylene gas are stored. Any one of the above is reloaded by the operator 5 at a remote location. Therefore, according to the product determination server 10 according to the present embodiment, it is possible to prevent the freshness of the crops packed in the luggage from being lowered during transportation.

[Configuration of product judgment device]
Subsequently, a functional configuration of the product determination server according to the present embodiment will be described. FIG. 2 is a block diagram illustrating the configuration of the product determination server according to the first embodiment. As shown in FIG. 2, the product determination server 10 includes a communication I / F (interface) unit 11, an item information storage unit 12, a production rate storage unit 13a, an influence degree storage unit 13b, and a load storage unit 14a. And a distance storage unit 14b. Further, the product determination server 10 includes an image analysis unit 15, an acquisition unit 16, a derivation unit 17, a determination unit 18, and a notification control unit 19. In addition to the functional units shown in FIG. 2, the product determination server 10 has various functional units included in a known server device, such as various input devices and audio output devices.

  Among these, the communication I / F unit 11 is an interface that performs communication control with other devices such as the camera 30 and the portable terminal 50. For example, the communication I / F unit 11 receives a loading platform image from the camera 30 or transmits information such as a notification screen and sound generated by the notification control unit 19 described later to the portable terminal 50. As an aspect of the communication I / F unit 11, a network interface card (NIC) such as a LAN card or a modem can be employed.

  The item information storage unit 12 is a storage unit that stores item information of crops. As an example, the item information storage unit 12 is referred to by an image analysis unit 15 to be described later in order to identify which crop is packed by the package analyzed from the loading platform image.

  As one aspect of such item information, data in which the item name of the agricultural product and its item name code are associated can be employed. The “product name” is a name of a crop such as a vegetable or a fruit, and is displayed on a package in which the crop is packed. In the following, description will be made on the assumption that agricultural products are packed with rectangular parallelepiped cardboard. In this case, the “product name” is displayed on the side or top surface of the rectangular parallelepiped forming the cardboard. The “product name code” indicates a code assigned in advance to specify the product name of the agricultural product. These “product name” and “product name code” are associated with each other in order to cause the image analysis unit 15 described later to search for a “product name code” corresponding to the product name using the “product name” of the package analyzed from the cargo bed image as a search key. Made.

  FIG. 3 is a diagram illustrating a configuration example of information stored in the product information storage unit 12. In the example of FIG. 3, the product name code of the product name “apple” is “001”, the product name code of the product name “watermelon” is “002”, and the product name code of the product name “banana” is “003”. Indicates. In addition, in the examples of FIGS. 3 to 5, Japanese product names are illustrated. However, when agricultural products imported from overseas or agricultural products exported to foreign countries are displayed on the package, the language of the import destination or export destination Define the product name. In the example of FIG. 3, the product name and product name code of the fruits are illustrated as the agricultural products. However, product names and product name codes of other agricultural products such as vegetables and flowers can be defined in addition to the fruits. Further, the item information is not necessarily stored in a table format, and may be stored in another format.

  The production rate storage unit 13a is a storage unit that stores production rate information of ethylene gas due to luggage. As an example, the output rate storage unit 13a is referred to by the registration unit 15c and the acquisition unit 16 described later in order to acquire the ethylene gas output rate of the cargo from which the product name code of the crop is obtained.

  As one aspect of the output rate information, data in which the product name code and the output rate are associated can be employed. The “production rate” here refers to the concentration (for example, ppm: Parts Per Million) of ethylene gas produced as a total amount of crops packed in a predetermined capacity of luggage. In addition, although the case where the concentration of ethylene gas produced as the total amount of the crops packed in the baggage is stored as an output rate is illustrated here, the concentration of ethylene gas per crop may be stored as the output rate. Good. Further, the capacity of the package may be an arbitrary capacity, and is increased or decreased by changing the size of the package of the package.

  FIG. 4 is a diagram illustrating a configuration example of information stored in the output rate storage unit 13a. The magnitude relationship between the output rate values “A1”, “A2”, and “A3” shown in FIG. 4 is assumed to be “A3 <A2 <A1”. The example of FIG. 4 indicates that the production rate of ethylene gas in a package packed with apples with the product name code “001” is “A1 (ppm)”. Further, in the example of FIG. 4, it is shown that the ethylene gas production rate of the package packed with the watermelon having the product name code “002” is “A2 (ppm)”. Furthermore, in the example of FIG. 4, it is shown that the ethylene gas production rate of a package packed with bananas having the product name code “003” is “A3 (ppm)”. In addition, although the case where the density | concentration of ethylene gas was used as an output rate was illustrated here, it should just be the parameter | index showing the quantity of the ethylene gas which a load produces, and even if it is the output degree indicated by the frequency and the level It doesn't matter. The output rate information does not necessarily need to be stored in a table format, and may be stored in another format.

  The influence degree storage unit 13b is a storage part that stores influence degree information indicating the degree to which the agricultural products packed in the luggage are affected by the ethylene gas. As an example, the influence level storage unit 13b is referred to by a registration unit 15c and an acquisition unit 16 described later in order to acquire the degree of influence due to ethylene gas of a package from which a product name code of a crop is obtained.

  As an aspect of the influence degree information, data in which the product name code, the influence degree, and the influence content are associated can be employed. The “influence degree” here is an index representing the degree to which the total amount of the cargo of a predetermined capacity in which agricultural products are packed is affected by ethylene gas. For example, a level value ranked in an arbitrary number of stages Can be adopted. The “effect content” refers to the content of freshness that is impaired by the effects of ethylene gas on the crops packed in the luggage.

  FIG. 5 is a diagram illustrating a configuration example of information stored in the influence storage unit 13b. In the example shown in FIG. 5, level values ranked in five levels of 1 to 5 are adopted as the degree of influence, and the lower the level value, the more likely the crops are affected by ethylene gas.

  In the example of FIG. 5, the degree of influence of a package packed with apples with the product name code “001” is “2”, and when the apples are affected by ethylene gas, the skin is tanned. Further, in the example of FIG. 5, the impact degree of the package packed with the watermelon having the product name code “002” is “3”, and when the watermelon is affected by the ethylene gas, the corruption proceeds. Further, in the example of FIG. 5, the influence degree of the package packed with the banana with the product name code “003” is “1”, and when the banana is affected by ethylene gas, the rot progresses. In the example of FIG. 5, tanning and rot are illustrated as the influence contents, but the influence contents are not limited to those shown in the figure, and other than the tanning and rot, the influence contents suitable for each crop such as mold and softening are present. be registered. Further, the above-mentioned influence degree information does not necessarily need to be stored in a table format, and may be stored in another format.

  In the example of FIGS. 4 and 5, the product determination server 10 exemplifies the case where the output rate and the impact level of the crop are separately divided into the output rate storage unit 13a and the impact level storage unit 13b. The disclosed apparatus is not limited to this. For example, in the disclosed apparatus, a storage unit that integrates two storage units, namely, the output rate storage unit 13a and the influence degree storage unit 13b, for example, a storage unit that stores the output rate and the influence degree for each product name code of a crop. You can keep it.

  The load storage unit 14 a is a storage unit that stores various pieces of information on the luggage loaded on the loading platform of the vehicle 3. As an example, the load storage unit 14a is used to manage information such as the position, the output rate, and the degree of influence of the load loaded on the loading platform of the vehicle 3. As an aspect of the cargo storage unit 14a, data in which a loading number, a product name code, a cargo position, a production rate, and an influence degree are associated is stored.

  The “loading number” here refers to a sequence number assigned by an image analysis unit 15a (to be described later) in the order in which the load is loaded on the loading platform of the vehicle 3. As an example of the numbering of the loading number, the loading number “01” is assigned to the package loaded first, and the loading number “02”,... “XX” is numbered in ascending order. As described above, when serial numbers are assigned to the loads, the order in which the loads are loaded can be managed by the load storage unit 14a. In addition, although the case where the loading numbers are numbered in ascending order is illustrated here, the loading numbers may be numbered in descending order, or different loading numbers may be randomly numbered.

  The “loading position” indicates a position where the load is loaded on the loading platform of the vehicle 3. As an example, it is assumed that the occupied area occupied by the loading in the loading platform of the vehicle 3 is represented by the center of gravity position of the loading. The “position of gravity of the load” is a coordinate (X, Y, Z) expressed in the local coordinate system of the loading platform in which an arbitrary point in the loading platform of the vehicle 3 is defined as the origin (0, 0, 0). And As an example, in the local coordinate system of the loading platform, the XY plane is a horizontal plane, the X axis represents the longitudinal direction of the loading platform, the Y axis represents the short direction, and the Z axis represents the height direction perpendicular to the XY plane. Assume a case.

  As one aspect of the aspect in which such a loading position is registered, there is a case where when a new load is loaded on the loading platform of the vehicle 3, the loading position analyzed from the loading platform image by the image analysis unit 15 described later is registered. Can be mentioned. In addition, as one aspect of the situation in which the load position is updated, when the load is reloaded at another position, the load position after the reloading analyzed from the loading platform image by the image analysis unit 15 described later is reloaded. There is a case where it is updated by overwriting the previous loading position. In addition, as one aspect of the situation in which the load position is referred to, in order to derive the distance between the loads before the determination unit 18 described later determines the loading of the load, the load position is determined by the release unit 17 described later. Is read.

  FIG. 6 is a diagram illustrating a configuration example of information stored in the load storage unit 14a. In the example of FIG. 6, it is indicated that the loading position of the apple with the product name code “001” first loaded on the loading platform of the vehicle 3 is (X1, Y1, Z1). Furthermore, the output rate of the load packed with apples is “A1 (ppm)”, and the influence degree of the apples packed in the load is “2”. Further, in the example of FIG. 6, the loading position of the watermelon of the product name code “002” loaded second on the loading platform of the vehicle 3 is (X2, Y2, Z2). Furthermore, the output rate of the load packed with watermelon is “A2 (ppm)”, and the influence degree of the watermelon packed in the load is “3”. In the example of FIG. 6, the case where two pieces of apple and watermelon are loaded on the loading platform is illustrated. However, the number of entries in the loading storage unit 14 a is not fixed to two, but loaded on the loading platform. Entries are created or deleted as the number of packages being changed changes.

  The distance memory | storage part 14b is a memory | storage part which memorize | stores the warning distance between the cargoes which perform the warning by the alerting | reporting control part 19 mentioned later. As an example, the distance storage unit 14b is referred to by the determination unit 18 described later in order to obtain a warning distance to be compared with the distance between the loads derived by the deriving unit 17 described later. As an aspect of the distance storage unit 14b, data in which a warning distance is associated with each combination of output rate and influence degree is stored.

  Here, the warning distance is set based on the production rate of one of the two packages and the degree of influence of the other package. In this way, the output rate of one package and the influence level of the other package are used to set the warning distance. The output rate of one package, the influence level of the other package, and the distance between loads This is because they have the following correlation with each other. In other words, there is a correlation that the higher the output rate of one baggage, the higher the influence of the other baggage, and the smaller the distance between the two loads, the greater the effect that the other baggage receives from ethylene gas. . Therefore, if the degree to which the freshness of the other baggage is tolerated is determined for the combination of the production rate of one baggage and the influence level of the other baggage, the above three-way correlation algorithm is defined. In use, it is possible to obtain a distance where it is preferable to keep the packages away from each other as much as possible. The distance thus obtained is used as the warning distance.

  FIG. 7 is a diagram illustrating a configuration example of information stored in the distance storage unit 14b. The magnitude relationship between the output rates “a”, “b”, “c”, and “d” shown in FIG. 7 is assumed to be “d <c <b <a”. It should be noted that the output rates “a”, “b”, “c”, and “d” shown in FIG. 7 and the output rates “A1”, “A2” of the goods with the product name codes “001” to “003” shown in FIG. ”And“ A3 ”are assumed to be“ d <A3 <c <A2 <b <A1 <a ”.

  In the example of FIG. 7, when the production rate of ethylene gas is the section “a to b”, compared to the case where the production rate of ethylene gas is the section “b to c” or the section “c to d”, A long warning distance is defined even if the warning distance is associated with the same degree of influence. In addition, when the ethylene gas production rate is in the section “b to c”, the warning distance associated with the same degree of influence is compared to when the ethylene gas production rate is in the section “c to d”. Long warning distances are defined even if they exist. Further, when the ethylene gas production rate is in the section “c to d”, the influence degree is the same as in the case where the ethylene gas production rate is the section “a to b” or the section “b to c”. Even for the associated warning distance, a short warning distance is defined. Further, when comparing the warning distances between sections having the same ethylene gas production rate, a shorter warning distance is defined as the influence degree is higher, that is, as the influence level value is lower.

  A semiconductor memory element or a storage device can be adopted as the storage unit such as the product information storage unit 12, the output rate storage unit 13a, the influence degree storage unit 13b, the load storage unit 14a, and the distance storage unit 14b. For example, examples of the semiconductor memory element include a video random access memory (VRAM), a random access memory (RAM), a read only memory (ROM), and a flash memory. Examples of the storage device include storage devices such as a hard disk and an optical disk.

  The image analysis unit 15 is a processing unit that analyzes the loading platform image received from the camera 30. As shown in FIG. 2, the image analysis unit 15 further includes a detection unit 15a, an identification unit 15b, and a registration unit 15c.

  Among these, the detection part 15a is a process part which detects the motion of a load between the frames of a loading platform image. As an example, the detection unit 15a monitors whether or not a predetermined feature related to packing of a package, such as a cardboard color, a pattern, or a shape, exists in a region detected as a difference between frames of the loading platform image. . Thereby, the detection unit 15a detects the start of the load moved by the worker 5. Then, when a feature relating to the packing of the package is detected between the frames of the loading platform image, the detection unit 15a collects the movement of the luggage until no difference is detected between the frames of the loading platform image thereafter. As a result, the detection unit 15a detects the stoppage of the load that has been moved by the worker 5.

  Thereafter, when no difference is detected between the frames of the loading platform image, the detection unit 15a detects any movement of the load that has been detected on the loading platform image so far from any of the following entry locus, saddle locus, or departure locus. It is determined whether it corresponds to the locus of. Based on this determination, the detection unit 15a detects whether a load loading operation, a load reloading operation, or a load unloading operation has been performed from the loading platform image.

  The “entry trajectory” here refers to a trajectory entering the inside of the cargo bed in the order of the outside of the cargo bed of the vehicle 3, the doorway, and the inside of the cargo bed. In addition, the “haze trajectory” refers to a trajectory that wanders inside the loading platform of the vehicle 3. Further, the “withdrawal locus” refers to a locus of leaving toward the outside of the loading platform in the order of the inside of the loading platform of the vehicle 3, the entrance / exit, and the outside of the loading platform.

  For example, when the movement of the load detected on the loading platform image corresponds to the “entry trajectory”, it can be estimated that the loading work that the worker 5 loads on the loading platform of the vehicle 3 has been performed. In this case, in order to manage information related to the load newly loaded on the loading platform of the vehicle 3, the load number is assigned by the registration unit 15c, and a new entry is created in the load storage unit 14a. Thereafter, in the new entry, the product name code of the crop identified from the package, the calculation rate and the degree of influence of the package, and the load position of the package are registered by the registration unit 15c described later.

  In addition, when the movement of the load detected on the loading platform image corresponds to the “徘徊 locus”, it can be estimated that the worker 5 has performed a reloading operation for reloading the loading to another place in the loading platform. In this case, in order to update the load position of the load changed by reloading, the load position of the load in the load storage unit 14a is updated by the registration unit 15c described later.

  In addition, when the movement of the load detected on the loading platform image corresponds to the “disengagement locus”, it can be estimated that the worker 5 has performed the unloading operation of loading the load out of the vehicle 3. In this case, the entry of the loading number corresponding to the package whose loading has been detected, that is, the record including the loading number, the product name code, the loading position, the production rate, and the degree of influence is deleted by the registration unit 15c described later.

  The identification unit 15 b is a processing unit that identifies a load loaded on the loading platform of the vehicle 3. Explaining this, the identification unit 15b recognizes the character displayed on the load when the detection unit 15a detects the loading or unloading of the package. Then, the identification unit 15b searches the item information storage unit 12 for the character recognition result recognized from the cargo on the loading platform image, that is, the “item name code” of the crop corresponding to the “item name”. At this time, when the loading of the package is detected by the detection unit 15a, the identification unit 15b corresponds to the load number of the package whose loading is detected by the detection unit 15a, using the product name code retrieved from the product information storage unit 12. Add and register. On the other hand, the identification unit 15b outputs the product name code retrieved from the product information storage unit 12 to the later-described acquisition unit 16 when the reloading of the package is detected by the detection unit 15a. In addition, OCR (Optical Character Reader) is employ | adopted as one aspect | mode of the identification part 15b.

  The registration unit 15 c is a processing unit that registers information regarding the luggage loaded on the loading platform of the vehicle 3. As an example, the registration unit 15c uses the load storage unit 14a to manage the information on the load currently loaded on the loading platform of the vehicle 3, so that the product name code, the calculation rate, the influence degree, and the load position are stored in the load storage unit. 14a is registered or updated.

  For example, when the loading is detected by the detection unit 15a, the registration unit 15c assigns a load number and creates a new entry in the load storage unit 14a. Thereafter, the registration unit 15c registers the product name code of the crop identified from the package by the identification unit 15b in a new entry in the cargo storage unit 14a. In addition, the registration unit 15c reads the output rate and the degree of influence corresponding to the product name code of the load detected to be loaded from the output rate storage unit 13a and the influence level storage unit 13b, and registers them in a new entry in the load storage unit 14a. . Furthermore, the registration unit 15c analyzes the pixel position on the cargo bed image of the load detected to be loaded, for example, the pixel position where the center of gravity of the luggage exists, converts the pixel position into the three-dimensional local coordinates of the cargo bed, The loading position is registered in a new entry in the loading storage unit 14a.

  The association between the pixel position (x, y) on the loading platform image and the loading platform local coordinate system (X, Y, Z) is previously stored in the internal memory of the registration unit 15c (not shown). To do. For example, when the loading platform of the vehicle 3 is a rectangular parallelepiped, this association is obtained by associating the corner of the loading platform, that is, the loading platform local coordinates of the top of the rectangular parallelepiped with the pixel position of the corner of the loading platform on the loading platform image. . Further, for example, by including a marker whose position can be detected on the loading platform image on the wall surface of the loading platform of the vehicle 3 and specifying the marker position from the loading platform image including such a marker, the above association can be performed. It can also be obtained.

  In addition, when the reloading is detected by the detection unit 15a, the registration unit 15c analyzes the pixel position on the cargo bed image of the baggage whose reloading is detected, and converts the pixel position into the three-dimensional local coordinates of the cargo bed. After the conversion, the loading position after reloading is overwritten and updated on the loading position before loading. When the shipment is detected by the detection unit 15a, the registration unit 15c enters the entry of the loading number corresponding to the package for which loading has been detected, that is, the loading number, the product name code, the loading position, the output rate, and the influence. The record including the degree is deleted from the load storage unit 14a.

  The acquisition unit 16 is a processing unit that acquires the output rate and the degree of influence of the package using the load storage unit 14a. As an example, the acquisition unit 16 activates the process when the load position stored in the load storage unit 14a is updated, that is, when loading or unloading is detected. In this case, the acquisition unit 16 acquires the output rate and the degree of influence corresponding to the item name code of the package in which loading or reloading is detected, and the output rate and the degree of influence of the package that has been loaded so far get. In the following, a package in which loading or reloading is detected is expressed as “first luggage”, and a package that has already been loaded before loading or reloading is detected as “second luggage”. May be expressed. In this example, the output rate and the degree of influence are acquired for both the first and second packages, but only the output rate is acquired for one package and the other package is acquired. Only the degree of influence may be acquired.

  The deriving unit 17 is a processing unit that derives the distance between the packages. As an example, the deriving unit 17 reads the loading position (a, b, c) corresponding to the item name code of the first package from the loading storage unit 14a. Furthermore, the deriving unit 17 reads the loading position (α, β, γ) corresponding to the item name code of the second package from the loading storage unit 14a. After that, the deriving unit 17 determines the loading position (a, b, c) of the first load and the loading position (α, β, γ) of the second load, for example, the formula of the three square theorem. The distance d between the first package and the second package is derived by substituting into etc. At this time, the deriving unit 17 can also derive various parameters related to the distance including the linear distance between the first and second packages. For example, the derivation unit 17 can calculate the horizontal distance when the first luggage and the second luggage are projected on a horizontal plane, the vertical distance when the first luggage and the second luggage are orthogonally projected, and the one distance from the other luggage to the other. It is also possible to derive an altitude angle indicating how much the load is observed.

  The determination unit 18 is a processing unit that determines the product stacking. As an example, it is determined whether or not there is a possibility that the freshness of the second load may be reduced by loading or reloading the first load on the loading platform of the vehicle 3, and the second load that has already been loaded. It is also determined whether or not there is a risk of the freshness of the first package being reduced by the package. In addition, although the case where both the fear of the freshness fall of the 2nd load and the fear of the freshness fall of the 1st load is judged here is illustrated, it is assumed that the determination is performed only for one of the loads. It doesn't matter.

  Explaining this, the determination unit 18 determines that the distance between the first baggage and the second baggage derived by the derivation unit 17 is the first baggage production degree and the first baggage of the distances stored in the distance storage unit 14b. It is determined whether or not the warning distance D1 is equal to or less than the impact degree of the second load. For example, if the item name code of the first package is an apple with “001” and the item code of the second package is “banana” with a “003”, the output rate of the first package with apples packed is “A1” and the influence degree of the second baggage packed with bananas is “1”. Therefore, the distance between the first luggage and the second luggage is equal to or less than the warning distance D1 (= “500 cm”) corresponding to the combination of the production rate “A1” of the first luggage and the influence degree “1” of the second luggage. Whether or not is determined by the determination unit 18. If the distance between these packages is equal to or less than the warning distance D1, the freshness of the second package may be lowered by ethylene gas if left as it is. In this case, the determination unit 18 includes, in a warning list stored in an internal memory (not shown), the item name code of the second package to be warned, the item name code of the first package that causes a decrease in freshness, An entry that associates the warning distance D1 is created.

  Further, the determination unit 18 determines that the distance between the first baggage and the second baggage derived by the derivation unit 17 is the second baggage production degree and the first baggage out of the distances stored in the distance storage unit 14b. It is determined whether or not the warning distance D2 is less than or equal to the degree of influence. If the distance between these packages is equal to or less than the warning distance D2, if left as it is, the freshness of the first package may be reduced by ethylene gas. In this case, the determination unit 18 includes, in a warning list stored in an internal memory (not shown), the load number of the first package to be warned, the load number of the second package that causes a decrease in freshness, An entry that associates the warning distance D2 is created.

  In this way, the determination unit 18 determines that all the packages whose loading or reloading has been detected by the detection unit 15a are the packages stored in the loading storage unit 14a and whose loading or reloading has not been detected. Until the product is determined between the above, the above determination is repeated.

  FIG. 8 is a diagram illustrating an example of a warning list. In the example illustrated in FIG. 8, a case where the freshness of the second load may be reduced by loading or reloading the first load on the loading platform of the vehicle 3 is illustrated. In the case of the warning list shown in FIG. 8, a warning that there is a risk of a decrease in freshness due to the apple that was first loaded with the banana that was loaded third on the loading platform of the vehicle 3 will be described later. It is defined to be executed by the unit 19. Furthermore, in the case of the warning list shown in FIG. 8, it is defined that the notification control unit 19 described later executes a recommendation that it is preferable to separate the two from 500 cm.

  The notification control unit 19 is a processing unit that controls execution of notification to the mobile terminal 50. As an example, the notification control unit 19 generates a notification screen that defines the content of notification to be warned or recommended by the mobile terminal 50 in accordance with the warning list created by the determination unit 18. At this time, if there is no entry in the warning list, the notification to the portable terminal 50 is not executed. Then, the notification control unit 19 transmits the generated notification screen to the mobile terminal 50. The notification screen transmitted by the notification control unit 19 in this way is displayed by the mobile terminal 50. Here, the case where the notification is executed by displaying the notification screen on the portable terminal 50 is illustrated, but the notification may be executed by causing the portable terminal 50 to output the notification voice.

  As an example, the notification control unit 19 generates a notification screen in which warning content and recommended content are notified by text. FIG. 9 is a diagram illustrating an example of a notification screen. In the example of the notification screen shown in FIG. 9, the fact that the banana is affected by the ethylene gas by the apple, the freshness content that the banana is damaged by the ethylene gas, and further, the banana and the apple are placed apart from the warning distance of 500 cm. A recommendation to the effect is announced. With the notification screen shown in FIG. 9, the operator 5 can grasp that there is a risk of banana rot in the current stacking even without knowledge that the stacking of bananas and apples is bad. Further, the notification screen shown in FIG. 9 allows the worker 5 to grasp that the bananas or apples should be re-loaded apart from the warning distance of 500 cm, so that the number of times of re-loading the load can be reduced.

  As another example, the notification control unit 19 generates a notification screen that notifies the loading position of the load that causes a decrease in freshness together with the layout of the loading platform of the vehicle 3 in addition to the notification by the above sentence. FIG. 10 is a diagram illustrating an example of a notification screen. In the example of the notification screen shown in FIG. 10, in addition to the notification content shown in FIG. 9, the top view of the loading platform of the vehicle 3 further includes an image in which the loading position of the apple that causes the banana freshness reduction is drawn. It is. With the notification screen shown in FIG. 10, the operator 5 can more intuitively grasp a place where a banana that has been loaded or reloaded later should not be reloaded, and can further reduce the number of reloads.

  In the example of FIG. 10, the case where the top view of the loading platform of the vehicle 3 is displayed on the portable terminal 50 is illustrated, but the side view of the loading platform of the vehicle 3 may be displayed on the portable terminal 50, A perspective view of the loading platform of the vehicle 3 may be displayed on the portable terminal 50 as a three-dimensional image. As an example, when the distance of the Z coordinate between the first load and the second load, that is, the distance in the height direction of the load platform is equal to or greater than the threshold value, the notification control unit 19 has a side surface of the load platform of the vehicle 3. When the figure is adopted and the distance of the Z coordinate is less than the threshold value, the top view of the loading platform of the vehicle 3 is adopted as the notification screen. As a result, the visibility of the distance in the height direction between the loads can be improved. The disclosed device is not limited to the above example, and determines whether to adopt the top view of the loading platform of the vehicle 3 or the side view of the loading platform of the vehicle 3 depending on whether the altitude angle is equal to or greater than a threshold value. Also good.

  As a further example, in addition to the notification by the above sentence, the notification control unit 19 recommends recommending the loading position of the load to be warned and other loads as well as the loading position of the load as well as the loading of the load. A notification screen in which the restacking region is also notified is generated. FIG. 11 is a diagram illustrating an example of a notification screen. In the example of the notification screen shown in FIG. 11, together with the notification content shown in FIG. 10, the loading positions of apples and watermelons already loaded are drawn in a top view when the loading platform of the vehicle 3 is viewed from above. Furthermore, in the example of the notification screen shown in FIG. 11, an area that is estimated to be less likely to be affected by ethylene gas due to already loaded apples and watermelon is displayed as a recommended reload area by painting. Here, as one aspect of the recommended reloading area, an area on the loading platform of the vehicle 3 that is separated from all the second loads by the warning distances D1 and D2 is used after being specified by the notification control unit 19. With the notification screen shown in FIG. 11, the operator 5 can more intuitively know where to place the bananas that have been loaded or reloaded later, and can further reduce the number of times of reloading.

  Note that various integrated circuits and electronic circuits can be employed for the image analysis unit 15, the acquisition unit 16, the derivation unit 17, the determination unit 18, and the notification control unit 19. Further, a part of the functional unit included in the image analysis unit 15 may be another integrated circuit or an electronic circuit. For example, an ASIC (Application Specific Integrated Circuit) is an example of the integrated circuit. Examples of the electronic circuit include a central processing unit (CPU) and a micro processing unit (MPU).

[Process flow]
Next, the flow of processing of the product determination server 10 according to the present embodiment will be described. Here, after describing the processing procedure of (1) cargo management processing executed by the product judgment server 10, the processing procedure of (2) notification control processing will be described.

(1) Load Management Process FIG. 12 is a flowchart illustrating the procedure of the load management process according to the first embodiment. This cargo management process is a process that is repeatedly executed as long as the cargo bed image is supplied from the camera 30, and is activated when the movement of the cargo is detected between frames of the cargo bed image by the detection unit 15a.

  As shown in FIG. 12, when the loading of the package is detected by the detection unit 15a (step S101, Yes), the registration unit 15c assigns a load number and creates a new entry in the load storage unit 14a. (Step S102). Subsequently, the registration unit 15c registers the item name code of the package identified from the package by the identification unit 15b in a new entry in the cargo storage unit 14a (step S103).

  Then, the registration unit 15c reads the output rate and the degree of influence corresponding to the item name code of the package whose loading has been detected from the output rate storage unit 13a and the influence level storage unit 13b, and registers them in a new entry in the load storage unit 14a. (Step S104). Thereafter, the registration unit 15c registers the loading position of the load detected to be loaded in a new entry in the load storage unit 14a (step S105), and ends the process.

  If the reloading of the load is detected by the detection unit 15a (step S106, Yes), the registration unit 15c updates the load position of the load detected to be reloaded by overwriting the load position before loading. (Step S105), and the process ends.

  Further, when the loading of the load is not detected by the detection unit 15a (No in Step S106), this corresponds to the case where the load is loaded from the loading platform of the vehicle 3. Therefore, the registration unit 15c deletes the entry of the loading number corresponding to the package for which loading has been detected from the loading storage unit 14a (step S107), and ends the process.

  Note that the processes of steps S101 and S106 shown in FIG. 12 do not have to be executed in the order shown, and can be executed in a mutually reversed order. Furthermore, the processes in steps S103 to S105 shown in FIG. 12 do not have to be executed in the order shown, and can be executed in a mutually reversed order.

(2) Notification Control Processing FIG. 13 is a flowchart illustrating a procedure of notification control processing according to the first embodiment. This notification control process is a process that is repeatedly executed as long as the loading platform image is supplied from the camera 30, and the process is started when the loading position stored in the loading storage unit 14a is updated.

  As illustrated in FIG. 13, the acquisition unit 16 reads from the cargo storage unit 14a the output rate and the degree of influence corresponding to the item name code of the first package in which loading or reloading has been detected (step S301). The deriving unit 17 reads the loading position corresponding to the item name code of the first package from the loading storage unit 14a (step S302).

  Thereafter, the acquisition unit 16 reads the production rate and the influence degree of the second baggage loaded before the first baggage is loaded or reloaded from the load storage unit 14a (step S303). Subsequently, the deriving unit 17 reads the loading position corresponding to the item name code of the second package from the loading storage unit 14a (step S304).

  Then, the deriving unit 17 derives the distance d between the first luggage and the second luggage by substituting the loading position of the first luggage and the loading position of the second luggage into a predetermined formula (Step S1). S305).

  Subsequently, the determination unit 18 determines the warning distance D1 that warns of a decrease in freshness of the second baggage, that is, the yield of the first baggage and the influence of the second baggage out of the distances stored in the distance storage unit 14b. The corresponding warning distance D1 is read (step S306). Further, the determination unit 18 corresponds to the warning distance D2 that warns of a decrease in freshness of the first baggage, that is, the second baggage production degree and the influence of the first baggage among the distances stored in the distance storage unit 14b. The warning distance D2 to be read is read (step S307).

  Here, the determination unit 18 determines whether or not the distance between the first package and the second package derived by the deriving unit 17 is equal to or less than the warning distance D1 (step S308). At this time, if the distance between the first baggage and the second baggage is equal to or less than the warning distance D1 (step S308, Yes), the freshness of the second baggage may be reduced by ethylene gas if left as it is. is there. Therefore, the determination unit 18 includes, in the warning list stored in the internal memory (not shown), the item name code of the second package that is a warning target, the item name code of the first package that causes a decrease in freshness, and the warning distance D1. Is created (step S309). If the distance between the first luggage and the second luggage is greater than the warning distance D1 (No at Step S308), Step S309 is skipped and the process proceeds to Step S310.

  Subsequently, the determination unit 18 determines whether or not the distance between the first package and the second package derived by the deriving unit 17 is equal to or less than the warning distance D2 (step S310). At this time, if the distance between the first baggage and the second baggage is equal to or less than the warning distance D2 (Yes in step S310), the freshness of the first baggage may be reduced by ethylene gas if left as it is. is there. Therefore, the determination unit 18 includes, in the warning list stored in the internal memory (not shown), the item name code of the first package that is a warning target, the item name code of the second package that causes a decrease in freshness, and the warning distance D2. Is created (step S311). If the distance between the first luggage and the second luggage is greater than the warning distance D2 (No at Step S310), Step S311 is skipped and the process proceeds to Step S312.

  Then, until the determination of stacking is performed for all the packages other than the packages for which loading or unloading is detected (No in step S312), the packages to be processed as the second packages are stored in the load storage unit. The package stored in 14a is changed to an unprocessed package, and the processing from step S303 to step S311 is repeatedly executed.

  After that, when the determination of stacking is executed for all the packages other than the packages for which loading or unloading is detected (step S312, Yes), the notification control unit 19 has an entry in the warning list. It is determined whether or not (step S313). When there is no entry in the warning list (step S313, No), the notification control unit 19 ends the process without executing notification to the mobile terminal 50.

  If there is an entry in the warning list (step S313, Yes), the notification control unit 19 generates a notification screen that defines the content of the notification to be warned or recommended by the portable terminal 50 according to the warning list (step S313). S314). Thereafter, the notification control unit 19 transmits the generated notification screen to the portable terminal 50 (step S315), and ends the process.

  Note that the processes in steps S301 and S302 shown in FIG. 13 do not have to be executed in the order shown, and can be executed in a reversed order. Further, the processes in steps S303 and S304 shown in FIG. 13 do not have to be executed in the order shown in the drawing, and can be executed by switching their order. Furthermore, the processing between steps S305 to S307 shown in FIG. 13 does not need to be executed in the order shown, and can be executed by switching the order of each other. Further, the processes in steps S308 and S309 shown in FIG. 13 and the processes in steps S310 and S311 shown in FIG. 13 do not have to be executed in the order shown in the figure, and are executed by switching the order of each other. Can do.

[Effect of Example 1]
As described above, the stack determination server 10 according to the present embodiment identifies the crops packed in the luggage loaded on the loading platform of the vehicle 3, and the luggage which emits ethylene gas and the luggage whose freshness is reduced by ethylene gas. Notification is executed when is stacked nearby.

  At this time, when a warning is given to the operator 5 to load the packages apart, either a package packed with crops that produce ethylene gas on the loading platform of the vehicle 3 or a package whose freshness is reduced by ethylene gas. Are restacked by the operator 5 at a remote location. Therefore, according to the product determination server 10 according to the present embodiment, it is possible to prevent the freshness of the crops packed in the luggage from being lowered during transportation.

  Moreover, when the notification which encourages the use of an ethylene remover is given as an example of measures against ethylene, the ethylene remover is used for a package in which crops that produce ethylene gas are packed by the worker 5. Therefore, according to the product determination server 10 according to the present embodiment, it is possible to prevent the freshness of the crops packed in the package from being lowered during transportation. Furthermore, in the product determination server 10 according to the present embodiment, it is not always necessary to use an ethylene remover, and it is sufficient to use the ethylene remover only when a notification is given. It is also possible to increase the use efficiency.

  In addition, as an example of measures against ethylene, when a notice is given to encourage the use of special packaging that isolates or seals crops, crops that produce ethylene gas are isolated by special packaging, or there is a package whose freshness decreases due to ethylene gas. It is sealed with special packaging. Therefore, according to the product determination server 10 according to the present embodiment, it is possible to prevent the freshness of the crops packed in the package from being lowered during transportation. Furthermore, in the product determination server 10 according to the present embodiment, it is not always necessary to use special packaging, and it is only necessary to use special packaging when a notification is given, so that the use efficiency of the special packaging can be improved. .

  In addition, since the product determination server 10 according to the present embodiment implements notification by cloud computing, it is not necessary to modify hardware on the client terminal side such as the vehicle 3 or the mobile terminal 50.

  Further, the product determination server 10 according to the present embodiment is configured such that the distance between the first baggage and the second baggage is the first baggage production degree and the second baggage among the distances stored in the distance storage unit 14b. It is determined whether the distance is equal to or less than the warning distance corresponding to the degree of influence. For this reason, the product determination server 10 according to the present embodiment does not need to perform notification when the distance between the packages is larger than the warning distance. Therefore, according to the stack determination server 10 according to the present embodiment, when the freshness of the crops packed in the baggage is prevented from being lowered during transportation, and there is a sufficient distance between the packages, It is possible to eliminate the need for reloading or to eliminate the above-mentioned measures against ethylene.

  Furthermore, the product combination determination server 10 according to the present embodiment determines that the first package and the second package are stacked within the warning distance D1 or when the load is within the warning distance D2. In such a case, control is performed so that notification is executed. Therefore, in the product determination server 10 according to the present embodiment, not only the case where the first load affects the second load but also the influence of ethylene gas, the second load affects the first load. Even in the case of giving a notification, the notification can be executed without omission. Therefore, according to the product determination server 10 according to the present embodiment, it is possible to more accurately prevent the freshness of the crops packed in the package from being lowered during transportation.

  Although the embodiments related to the disclosed apparatus have been described above, the present invention may be implemented in various different forms other than the above-described embodiments. Therefore, another embodiment included in the present invention will be described below.

[Application example of product judgment]
For example, in the above-described first embodiment, a case where a package in which agricultural products are packed is stacked on one vehicle 3 is illustrated, but the disclosed apparatus is not limited thereto. For example, the disclosed apparatus may be configured such that when a package in which agricultural products are packed is loaded on the loading platform of one of a plurality of vehicles, the gas produced by one of the loads loaded on the same loading platform is used for the other. The same applies to the case of transshipment to a different loading platform when the load is affected.

  As an example, the disclosed apparatus includes the first article and the second article in the presence / absence of a range stored for each combination of the production degree and the influence degree by the range storage unit. It may be determined whether there is a range corresponding to the degree of influence of the article.

  As one aspect of such a range storage unit, the presence or absence of a range is stored in association with each combination of the output level and the influence level. Here, the presence / absence of a range indicates whether there is a range in which the other baggage is affected by the ethylene gas produced by one baggage, and, like the distance storage unit 14b, one of the two baggage items. It is set based on the production rate of one baggage and the degree of influence of the other baggage. For example, when the production rate of one package is low, the influence on the other package is small. Therefore, when the output rate of one piece of luggage is low, the range is set to no range regardless of the degree of influence of the other luggage. In addition, when the influence of one package is low, the influence of the other package is reduced. Therefore, when the influence degree of one baggage is low, no range is set regardless of the production degree of the other baggage.

  FIG. 14 is a diagram illustrating an example of an application example. “Low”, “medium”, and “high” shown in FIG. 14 indicate the output rate of one package or the degree of influence of the other package. Further, “◯” shown in FIG. 14 indicates that there is a range, and “X” shown in FIG. 14 indicates that there is no range. In the example of FIG. 14, the range “none” is set when the output rate of one package is “low” or when the output rate of the other package is “low”. Further, in the example of FIG. 14, the range “present” is set when the output rate of one package is “medium” or more and the output rate of the other package is “medium” or more.

  For this reason, in the disclosed apparatus, when the load accumulation determination is performed using the range storage unit shown in FIG. 14, the output rate of the first baggage is “low” or the second baggage is output. If the output rate is “low”, the notification to the portable terminal 50 is not executed. On the other hand, in the disclosed apparatus, if the output rate of one baggage is “medium” or more and the output rate of the other baggage is “medium” or more, the first baggage or the second baggage is different from the vehicle. The portable terminal 50 is informed that it is preferable to load it on the carrier. For this reason, in the disclosed apparatus, the freshness of the crops packed in the parcel is also being transported in the same manner as in the first embodiment, even when the parcel accumulation determination is performed using the range storage unit illustrated in FIG. Can be more accurately prevented.

[Application example of cargo storage unit]
In the first embodiment, the case where the center of gravity position of the load is adopted as the load position is illustrated, but the disclosed apparatus is not limited to this. For example, in the disclosed apparatus, the three-dimensional coordinates of the three-dimensional vertex forming the luggage can be adopted as the loading position. In this way, when the three-dimensional coordinates of the vertices of the solid forming the luggage are adopted as the loading position, it is possible to derive the shortest distance between the luggage instead of the center-of-gravity distance between the luggage. Judgment can be executed with higher accuracy.

[Application 1 of distance storage unit]
In the first embodiment, the case where the warning distance of the distance storage unit 14b is set using only the production rate of one of the two packages is illustrated, but the disclosed device is not limited thereto. For example, in the disclosed apparatus, the warning distance of the distance storage unit 14b can be set using not only the output rate of one package but also the output rate of the other package. As a result, the warning distance of the distance storage unit 14b can be set by bringing the degree to which the other baggage is actually affected by ethylene gas closer to the environment in which the baggage is actually loaded. Can be executed.

[Application example 2 of distance storage unit]
In the first embodiment, the case where the distance storage unit 14b stores one table is illustrated, but the disclosed apparatus is not limited thereto. As an example, the disclosed apparatus can hold a plurality of tables in the distance storage unit for each storage environment such as temperature and humidity. In this case, the lower the temperature or the lower the humidity, the less the respiration of crops and the more the growth is suppressed. Therefore, it is preferable to set the warning distance longer. Then, the disclosed apparatus can improve the accuracy of the load determination of the load by performing the load determination of the load using the warning distance corresponding to the temperature and humidity acquired via a sensor (not shown). . As another example, the distance storage unit may store warning distances for each coordinate axis of the X coordinate, the Y coordinate, and the Z coordinate. Here, ethylene gas has a lower specific gravity than air, and the higher the loading platform of the vehicle 3, the greater the influence of ethylene gas. Therefore, the warning distance of the Z coordinate is longer than the warning distance of the X coordinate and the Y coordinate. It is preferable to set. The disclosed apparatus determines whether or not any of the X coordinate distance, the Y coordinate distance, and the Z coordinate distance between the packages is within the warning distance, thereby determining the accuracy of the package stacking determination. Can be improved.

[Application example of notification]
In the first embodiment, the case where the notification is executed at the time when loading or reloading is performed is illustrated, but the disclosed device is not limited to this, and the disclosed device performs the notification at an arbitrary timing. Can do. As an example, the disclosed apparatus can perform notification by performing a load determination of a load before the first load loading operation or the reloading operation is completed. As another example, the disclosed apparatus accepts the quantity and name code of the packages to be loaded, and identifies the arrangement of the packages in which the distance between the packages is greater than the warning distances D1 and D2 for all combinations of packages. In addition, the placement of the luggage can be recommended. At this time, in the case where there is no arrangement of the packages in which the distance between the packages is larger than the warning distances D1 and D2 for all the combinations of packages, the disclosed apparatus can reduce the number of times that the warning distance D1 or D2 is less than or equal between the packages. It is also possible to recommend the least amount of luggage.

[Packaging packing]
In the first embodiment, the case where the crop is packed by cardboard is illustrated. However, the disclosed device can be applied even when the crop is loaded as it is on the loading platform of the vehicle 3 without being packed. In this case, by registering crop template images in advance and monitoring whether there is an image similar to each crop template image in the area detected as the difference between frames of the loading platform image What is necessary is to detect the movement of the crop. Thus, the disclosed apparatus can similarly detect crop loading, unloading and loading operations. Further, the disclosed apparatus can be similarly applied to the case where the disclosed apparatus is packed by a packing body other than cardboard, such as a car or a pallet. In this case, the movement of the car or the pallet may be detected by monitoring whether or not a pre-defined characteristic regarding the car or the pallet exists in the area detected as the difference between frames of the loading platform image. Thus, the disclosed apparatus can similarly detect crop loading, unloading and loading operations.

[Application to stand-alone]
In the first embodiment, the case where the server provides the client with a service for determining the stacking of the packages by cloud computing is illustrated, but the disclosed apparatus is not limited thereto. For example, in the disclosed device, when the mobile terminal 50 operates in a stand-alone manner without using the network 7, that is, the mobile terminal 50 includes the image analysis unit 15, the acquisition unit 16, the derivation unit 17, the determination unit 18, and the notification control unit. The same applies to the case of 19 functions.

[Application to aspects other than transportation]
In the above-described first embodiment, the case where the worker 5 loads the load on which the agricultural products are packed on the loading platform of the vehicle 3 is illustrated, but the disclosed apparatus is not limited thereto. For example, the disclosed apparatus can also be applied to cases where a package is transported by a container or stored in a warehouse in the process of distributing agricultural products. That is, it can be applied to a case where a plurality of types of luggage are placed in a spatially closed area such as a cargo bed, a container, and a warehouse. For example, in the case of a container or a warehouse, it is possible to similarly detect a loading operation, a loading operation, and a loading operation using a camera installed in the container or the warehouse.

[Use of RFID tags]
In the first embodiment, the case where the identification of the luggage and the registration of the loading position are performed from the loading platform image is illustrated, but the disclosed apparatus is not limited thereto. For example, the disclosed apparatus can identify a package by obtaining a product name code of a crop packaged in the package from an RFID (Radio Frequency Identification) tag attached to the package or an attached RFID tag. . Further, the disclosed apparatus can also register the loading position by acquiring the loading position where the luggage is loaded on the loading platform of the vehicle 3 from the RFID tag bundled with the luggage or the attached RFID tag.

[Application to other than crops]
In Example 1 described above, the case where the freshness of other crops is reduced by the ethylene gas produced by the crops is illustrated, but the disclosed apparatus is not limited thereto. The disclosed apparatus can be widely applied not only when crops are stacked, but also when the gas produced is not ethylene gas and the quality of the other article is deteriorated by the gas produced by one article. As an example, the disclosed apparatus can be applied to a case where an article such as seafood that produces an odor component and an article such as bread or clothing to which the odor component easily adheres.

  In this case, in the disclosed apparatus, instead of the ethylene gas production rate, the production rate relating to the odor component gas is registered in the production rate storage unit 13a for each article and for each odor component type. In the disclosed apparatus, instead of the influence degree of ethylene gas, the influence degree regarding the gas of the odor component is registered in the influence degree storage unit 13b for each article and for each kind of odor component. Furthermore, in the disclosed apparatus, instead of the warning distance of ethylene gas, the warning distance regarding the odor component gas is registered in the distance storage unit 14b for each type of odor component and for each combination of the production rate and the degree of influence. In addition, the disclosed apparatus determines whether there is a risk of quality deterioration in the second load due to the loading or reloading of the first load on the loading platform of the vehicle 3, or has already been loaded. It may be determined whether there is a risk of quality degradation of the first package due to the already completed second package. At this time, the product determination is preferably performed for each kind of odor component. The type of odor component may be a component having an irritating odor such as ammonia, a component emitted when the fish rots, or a component emitted when the eggs rot. Good.

[Distribution and integration of devices]
In addition, each component of each illustrated apparatus does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution / integration of each device is not limited to that shown in the figure, and all or a part thereof may be functionally or physically distributed or arbitrarily distributed in arbitrary units according to various loads or usage conditions. Can be integrated and configured. For example, the image analysis unit 15, the acquisition unit 16, the derivation unit 17, the determination unit 18, or the notification control unit 19 may be connected as an external device of the product determination server via a network. In addition, the image analysis unit 15, the acquisition unit 16, the derivation unit 17, the determination unit 18, or the notification control unit 19 is provided in a separate device, and is connected to the network to cooperate. You may make it implement | achieve a function. In addition, another device has all or part of the product information storage unit 12, the output rate storage unit 13a, the impact storage unit 13b, the load storage unit 14a, and the distance storage unit 14b, and cooperates by being connected to a network. Thus, the function of the product determination server 10 may be realized.

[Warning distance correction]
In the first embodiment, the case where the warning distance is determined for each combination of the output rate and the degree of influence stored in the distance storage unit 14b is illustrated, but the disclosed apparatus is not limited thereto. The disclosed apparatus does not use the warning distance stored in the distance storage unit 14b as it is for the processing, but may correct the warning distance and use it for the determination in S308 or S310. For example, even if a product with a high output rate and a product with a large impact (which is easily affected) are placed within the warning distance, the impact should be small if the time for such a state is short. Can be predicted. On the other hand, even if a product with a low output rate and a product with a low impact (hard to be affected) are placed beyond the warning distance, the impact will increase if the time for such a state is long. Can be predicted.

  Therefore, as the time for maintaining the state where a plurality of packages are placed, for example, if information on the transportation time or the storage time in the warehouse is obtained, the correction coefficient is larger than 1, and the longer the time, the longer the time. It is conceivable to set a correction coefficient such that the value becomes larger than when the value is short. A value obtained by multiplying the warning distance stored in the distance storage unit 14b by the correction coefficient may be used for the determination in S308 or S310. By doing in this way, if it is transport for a short time, the freedom degree of the position which can put a load can be raised, Therefore The freedom degree of the operation | work which loads a load can be raised.

  Further, instead of using the output rate for each product name code stored in the output rate storage unit 13a as it is in the process, the output rate may be corrected. For example, it is conceivable that the yield rate changes even immediately after harvesting and after a long time has passed since harvesting, even for the same agricultural product. Therefore, the amount of change over time of output is stored in advance for each product name code, and if the time since the harvest of the agricultural products in the luggage to be determined is known, the output rate is corrected using such information. It is possible. In the disclosed apparatus, the warning distance may be corrected instead of correcting the output rate using the amount of change in output over time.

[Production judgment program]
The various processes described in the above embodiments can be realized by executing a prepared program on a computer such as a personal computer or a workstation. In the following, an example of a computer that executes a product determination program having the same function as that of the above-described embodiment will be described with reference to FIG.

  FIG. 15 is a schematic diagram illustrating an example of a computer that executes a product determination program according to the first and second embodiments. As illustrated in FIG. 15, the computer 100 includes an operation unit 110 a, a speaker 110 b, a camera 110 c, a display 120, and a communication unit 130. Further, the computer 100 includes a CPU 150, a ROM 160, an HDD 170, and a RAM 180. These units 110 to 180 are connected via a bus 140.

  As shown in FIG. 15, the HDD 170 exhibits the same functions as the image analysis unit 15, the acquisition unit 16, the derivation unit 17, the determination unit 18, and the notification control unit 19 described in the first embodiment. The product judgment program 170a to be stored is stored in advance. The product determination program 170a is appropriately integrated or separated as in each component of the image analysis unit 15, the acquisition unit 16, the derivation unit 17, the determination unit 18, and the notification control unit 19 shown in FIG. Also good. In other words, all data stored in the HDD 170 need not always be stored in the HDD 170, and only data necessary for processing may be stored in the HDD 170.

  Then, the CPU 150 reads the product determination program 170 a from the HDD 170 and develops it in the RAM 180. Thus, as shown in FIG. 15, the product judgment program 170a functions as a product judgment process 180a. The product determination process 180a expands various data read from the HDD 170 in an area allocated to itself on the RAM 180 as appropriate, and executes various processes based on the expanded data. The product determination process 180a is performed by the image analysis unit 15, the acquisition unit 16, the derivation unit 17, the determination unit 18, and the notification control unit 19 illustrated in FIG. 2, for example, as illustrated in FIGS. Includes processing. In addition, each processing unit virtually realized on the CPU 150 does not always require that all processing units operate on the CPU 150, and only a processing unit necessary for the processing needs to be virtually realized.

  Note that the product determination program 170a is not necessarily stored in the HDD 170 or the ROM 160 from the beginning. For example, each program is stored in a “portable physical medium” such as a flexible disk inserted into the computer 100, so-called FD, CD-ROM, DVD disk, magneto-optical disk, or IC card. Then, the computer 100 may acquire and execute each program from these portable physical media. In addition, each program is stored in another computer or server device connected to the computer 100 via a public line, the Internet, a LAN, a WAN, etc., and the computer 100 acquires and executes each program from these. It may be.
