Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(First embodiment)
First, a first embodiment of the present invention will be described with reference to FIGS.
This embodiment exemplifies a case where the present invention is applied to an inventory management device installed in a store (convenience store or the like) as a lighting control device. FIG. 1 shows a wireless LAN (Local) constructed in a store (retail store). It is the block diagram which showed the (Area Network) system (system in a store).
This in-store system includes an inventory management device 1 that stores and manages inventory data for each product, a handy terminal (portable terminal device: inventory management terminal) 2 that is held by a product manager and that inputs product data, This is a wireless LAN system having an ECR (Electronic Cash Register) 3 that performs a settlement process (accounting process), an access point 4, and a lighting device 5.

  When the person in charge of merchandise inputs additional merchandise data (product code, the number of supplemented merchandise) from the handy terminal 2 when additional merchandise is replenished to the shelves constituting the merchandise display shelf 6, the entered merchandise data Is transmitted to the inventory management apparatus 1 through the access point 4 constituting the wireless LAN together with the shelf position number. Upon receiving the product data from the handy terminal 2, the inventory management device 1 performs an update process for adding the number of products (stock quantity) corresponding to the shelf position number and the product code, and from the ECR 3 at the time of accounting, the product data (product When the number of sales for each item is received, an update process for subtracting the number of products (the number of stocks) corresponding to the product is performed.

  In addition to the inventory management function that stores and manages the number of products for each product as described above, the inventory management device 1 has an illumination control function that controls the lighting fixture 5 in the store via each access point 4 that constitutes a wireless LAN. Have. This lighting control function is displayed (displayed) at the shelf position using the lighting fixture 5 arranged in association with the shelf position constituting the product display shelf 6 separately from the overall lighting in the store. This function controls the lighting effect on the product. Here, the inventory management device 1 controls the lighting effect according to the display status of the products displayed (displayed) at the shelf position (for example, the number of products in stock or the degree of reduction of the products), or displays (displays). Whether the product being sold is a specific product (for example, a special sale product or a recommended product) and whether the lighting effect is controlled or whether the product corresponds to a sales trend of the product (for example, a well-sold time zone or a day of the week) The lighting effect is controlled according to whether or not. In this case, a lighting effect limited to the product (shelf position) is performed.

  The lighting fixture 5 is provided with a lighting adjustment function and a camera function (imaging function), and is arranged in a one-to-one correspondence with each shelf position constituting the product display shelf 6. Illumination is performed obliquely from above. That is, a plurality of lighting fixtures 5 are arranged on the wall portion of the store facing the commodity display shelf 6 in correspondence with the number of steps of the shelf. For example, if the product display shelf 6 has a four-stage configuration, four lighting fixtures 5 are arranged correspondingly. Note that the lighting fixtures 5 are not limited to one-to-one correspondence with the shelf positions, but two or more lighting fixtures 5 are arranged corresponding to one shelf, depending on the width of the shelf. You may make it install.

FIG. 2 is a diagram for explaining the relationship between the commodity display shelf 6 and the lighting fixture 5.
The merchandise display shelf 6 has an upper and lower four-stage configuration in the illustrated example. In the drawing, the “L1” lighting fixture 5 illuminates the entire shelf position corresponding to the first (lowermost) shelf position. The L2 ″ lighting fixture 5 illuminates the entire shelf position corresponding to the second shelf position. Also, the “L3” lighting fixture 5 illuminates the entire shelf position corresponding to the third shelf position, and the “L4” lighting fixture 5 corresponds to the fourth (topmost) shelf position. Thus, the entire shelf position is illuminated.

  In the example shown in the figure, when the display status of the products is different for each shelf position, that is, the number of products displayed in the first (lowermost) shelf position and the fourth (uppermost) shelf position is large. However, this is a case where the number of products displayed in the second and third shelf positions is small. The inventory management device 1 controls the lighting effect on the product according to the display status of the product displayed at each shelf position. In this case, for example, for the shelf position with a small number of products. Provides clerk appeal lighting to urge shop assistants to replenish products, and for appeal to customers and purchase incentives for shelf positions with a large number of products. I try to produce.

  Here, the lighting effect is a color rendering that brings the product closer to the natural color depending on the brightness, light color, and lighting condition of the illumination light, and a variety of colors and lighting effects. It means to do. For example, if it is a lighting effect for customer appeal, the color of the product can be expressed more vividly by devising the lighting on the product, or it can be produced with a natural color and looks delicious. It is a lighting that can encourage customers' attention and purchasing motivation. In addition, if it is a lighting effect for clerk appeal, it means that the customer should be replenished with plain colors etc. so as not to stand out, or conversely express urgency by flashing lighting etc. doing. Such lighting effects (relationship between the product and the light color, brightness, etc.) can be arbitrarily set according to the intention of the store.

  The luminaire 5 is, for example, a halogen lamp or an LED (Light Emitting Diode) lamp. For example, a plurality of the luminaires 5 can be used to express the color of the product more vividly or to look natural and delicious. It is a lamp that can be switched to a light color (daylight color, daylight white, light bulb color, etc.). Note that the lighting fixture is not limited to a lamp capable of adjusting the light color, and may be a lighting fixture that converts a plurality of light colors using a filter or a mirror. The lighting fixture 5 is capable of adjusting the light color and has an adjustment function capable of adjusting the brightness of the light source, the illumination range, the illumination method, and the like, and lighting the product by operating this adjustment function. Is possible.

FIG. 3 is a block diagram showing basic components of the inventory management apparatus 1.
The CPU 11 that forms the core of the inventory management device 1 is a central processing unit that controls the overall operation of the inventory management device 1 according to various programs in the storage unit 12. The storage unit 12 stores various programs and information, and a program memory in which programs for realizing the present embodiment, various applications, and the like are stored in accordance with the operation procedures illustrated in FIGS. 7 to 9. In addition to an inventory management table ST that stores inventory data for each PG and product, it has a database DB for lighting control. An operation unit 13, a display unit 14, a wireless LAN communication unit 15, a clock unit 16, and the like are connected to the CPU 11 as input / output peripheral devices, and the CPU 11 controls their operations according to an input / output program.

FIG. 4 is a diagram for explaining the inventory management table ST on the inventory management apparatus 1 side.
The stock management table ST stores and manages information related to products such as the number of stocks for each product, and has items of “product code”, “shelf position number”, “stock number”, and “lighting device number”. ing. The “product code” and “shelf position number” are information indicating the correspondence between which product is displayed at which shelf position. If a shelf number for identifying the shelf position is added to each shelf of the commodity display shelf 6 by a barcode or the like, the barcode is read by the handy terminal 2 and transmitted to the inventory management device 1. By doing so, the “product code” and the “shelf position number” may be associated with each other. “Inventory” means the total number of products displayed at the shelf position, excluding products stored in the warehouse. The number of products displayed (displayed) is the number of stocks, and when that product is sold, The value decreases and increases as it is replenished.

  The “luminaire number” is information for identifying the luminaire 5 and is associated with the “product code” and the “shelf position number” to specify which product (shelf position) is illuminated with which luminaire 5. It becomes possible. In the present embodiment, the display status of each product is determined based on the number of stocks in the stock management table ST. However, the present invention is not limited to this number of stocks. The display status may be determined. In this case, as a new item in the inventory management table ST, an item “number of sales” that is updated (added) every time product data (number of sales for each product) is received from the ECR 3 at the time of accounting may be provided. .

FIG. 5 is a diagram for explaining a database DB for lighting control.
The database DB for lighting control has an exhibition status lighting control table LT1, a specific product lighting control table LT2, and a sales trend lighting control table LT3. The display status lighting control table LT1 stores control information for lighting effects corresponding to the display status for each product (shelf position). As shown in FIG. Each item includes “exhibition status”, “light source brightness”, “light color”, “illumination method”, and “illumination range”. In the “exhibition status” item, it is set whether to discriminate based on “product inventory quantity” or “product decrease degree” when discriminating the exhibition status of products. If “product inventory quantity” is set in the “exhibition status” item, the inventory management apparatus 1 sets the “inventory quantity” in the inventory management table ST to a predetermined limit value (for example, 20%) as described above. The display status of the product is determined according to whether it is less than or equal to.

  The limit value is a value that indicates the value to which the product should be replenished when the stock quantity decreases. For example, a value that varies depending on the product, such as the size of the product, may be arbitrarily selected. In the figure, it is set in the item “exhibition status” as shown in “product inventory quantity (less than limit value)” and “product inventory quantity (above limit value)”. Whether the inventory management apparatus 1 is “product inventory quantity (less than the limit value)” as the display status of the product based on whether or not the “stock quantity” in the inventory management table ST is less than a predetermined limit value. It is determined whether or not the product inventory quantity is equal to or greater than the limit value. As a result of this determination, the inventory management apparatus 1 is set in the exhibition status lighting control table LT1 in association with “product inventory quantity (less than limit value)” and “product inventory quantity (above limit value)”. Reading out the brightness of the light source, “light color”, “illumination method”, and “illumination range” as control information for lighting effects on the product, and transmitting it to the luminaire 5 corresponding to the product (shelf position) Thus, the lighting effect on the product is controlled.

  In addition, when “item reduction degree” is set in the item “exhibition status”, the inventory management apparatus 1 determines the exhibition status of the product by analyzing the captured image received and acquired from the lighting fixture 5. I am doing so. Here, the “product reduction degree” indicates the ratio of the blank space other than the space where the product is arranged to the entire shelf position where the product is displayed, and if the blank space at the shelf position is large, The degree of product decrease will increase. When the lighting fixture 5 that illuminates the shelf position receives and obtains an image of the entire shelf position from the lighting fixture 5, the inventory management device 1 obtains the degree of reduction of the product by analyzing the captured image. .

  The inventory management device 1 determines the product display status as “product reduction degree (above limit value)”, “product reduction degree” based on whether or not this reduction degree is greater than or equal to a limit value (for example, 80% or more). (Less than the limit value) ”is determined. As a result of this determination, the inventory management apparatus 1 is set in the exhibition status lighting control table LT1 in association with “product decrease degree (more than limit value)” and “product decrease degree (less than limit value)”. By reading out the brightness of the light source, “light color”, “illumination method”, and “illumination range” as control information for lighting effects on the product, and transmitting it to the lighting fixture 5 corresponding to the product, the product The lighting production is controlled. This reduction degree limit value (for example, 80% or more) is set in the item “Exhibition Status”.

  In this way, “Exhibition Status” can be set to either “Product Quantity” or “Product Decrease Degree”, which one to select is selected according to the characteristics of the product. do it. For example, if the product is large in size, “Product Decrease Degree” may be selected, and if the product is small in size, “Product Inventory Number” may be selected, or vice versa. May be. Furthermore, if there is a high possibility that shooting defects such as overexposure will occur due to the relationship between the color of the product and the position of the shelf, the “product inventory quantity” may be selected. Note that either “product inventory quantity” or “product reduction degree” is not arbitrarily set, but both of them may be set. In this case, when determining the display status of the product, the “product inventory quantity” may be less than the limit value and the “product reduction degree” may be more than the limit value.

  As a result of determining the display status of the product in the “light source brightness”, “light color”, “illumination method”, and “illumination range” as the control information for the lighting effect, whether the lighting effect is for customer appeal, Different contents are set depending on whether it is a lighting effect for salesclerk appeal. “Brightness of light source” and “light color” are, for example, information related to lighting for producing products so that they appear delicious or attracting customers' attention. Can be set. The “illumination method” includes a diffusion illumination method that diffuses illumination light, a spot illumination method that focuses illumination light, and an illumination method that blinks at regular intervals. The “illumination range” indicates the size of the illumination range (spot illumination area), and the contents thereof can be arbitrarily set by a user operation. In this case, according to the setting contents of “light color”, “illumination method”, and “illumination range”, an illumination effect is performed by combining any one item or a plurality of items.

  The specific product lighting control table LT2 stores control information for lighting effects corresponding to the specific product. As shown in FIG. 5 (2), the “product code”, “specific product”, “light source” Each item includes “brightness”, “light color”, “illumination method”, and “illumination range”. In the item “specific product”, “special product” and “recommended product” are set as the specific product. In the item of “specific product”, if the content is “sale product”, for example, a product that is cheaply sold at a time sale or the like, the time zone of the sale is set. If it is a “recommended product”, a date for selling the product is set. The inventory management device 1 determines whether or not it is a time zone or date corresponding to a specific product, and is associated with the “sale product (time zone)” and “recommended product (date)” in the exhibition status lighting control table. The “brightness of the light source”, “light color”, “illumination method”, and “illumination range” set in LT1 are read out as control information for lighting effects on the product, and the lighting fixture 5 corresponding to the product is read. By transmitting, the lighting effect on the product is controlled.

  The sales trend lighting control table LT3 stores control information for lighting effects corresponding to the sales trend. As shown in FIG. 5 (3), the “product code”, “sales trend”, “light source Each item includes “brightness”, “light color”, “illumination method”, and “illumination range”. In the item “Sales Trend”, a time zone and day of the week (sales trend) in which the product is sold well are set as an analysis result of the sales result of the product. The inventory management device 1 discriminates the sales trend of whether the product is selling well or whether it is a day of the week, and sales trend lighting control in association with “sales trend (time zone)” and “sales trend (day of the week)” The “brightness of the light source”, “light color”, “illumination method”, and “illumination range” set in the table LT3 are read out as control information for lighting effects on the product, and the lighting fixture 5 corresponding to the product is read. By transmitting, the lighting effect on the product is controlled.

  In the example shown in the figure, as a sales trend, a case where a well-sold time zone and a day of the week are set is shown. However, the present invention is not limited to this. You may make it set a week. Conversely, time zones, days of the week, and dates that cannot be sold may be set as sales trends. The inventory management device 1 analyzes the past sales performance for each product, and as a result, identifies the time zone, day of the week, date, and week when the product can be sold or cannot be sold as a sales trend, and whether or not this sales trend is met. Is determined.

FIG. 6 is a block diagram showing basic components of the lighting fixture 5.
The CPU 51 that forms the core of the lighting fixture 5 is a central processing unit that controls the overall operation of the lighting fixture 5 according to various programs in the storage unit 52. The storage unit 52 stores various programs and information, and stores a program for realizing the present embodiment. The CPU 51 is connected with a light source adjustment unit 53, an illumination range adjustment unit 54, an illumination direction adjustment unit 55, an illumination method adjustment unit 56, a wireless LAN communication unit 57, a camera unit 58, and the like as input / output peripheral devices. The CPU 51 controls these operations according to the input / output program.

  The configurations of the light source adjustment unit 53, illumination range adjustment unit 54, illumination direction adjustment unit 55, and illumination method adjustment unit 56 are arbitrary, but the light source adjustment unit 53 can switch the brightness and light color of the light source (lamp) 59. It has a configuration. The illumination range adjustment unit 54 is configured to be able to switch the illumination angle to a plurality of stages within a range of 20 degrees to 75 degrees, for example, when performing spot illumination. The illumination direction adjustment unit 55 is configured to be able to switch the illumination direction when performing spot illumination for focusing illumination light. The illumination method adjustment unit 56 is configured to be switchable between a diffuse illumination method for diffusing illumination light and a spot illumination method for focusing the illumination light at a shelf position. The wireless LAN communication unit 57 transmits / receives data to / from the inventory management device 1 via the access point 4, and performs lighting effects on the product (shelf position) in response to an instruction from the inventory management device 1. I try to control it. The camera unit 58 is a digital camera that captures the entire product (shelf position) from a diagonally upward direction at regular intervals. An image photographed by the camera unit 58 is sent to the inventory management apparatus 1 via the access point 4.

  Thus, in 1st Embodiment, the illumination control apparatus (inventory management apparatus 1) is an illumination control apparatus which controls the illumination to the inside of a store by an illumination means (lighting fixture 5), Comprising: The goods displayed in a store The display unit (the number of products in stock or the number of sales, the arrangement state of the product, the degree of reduction of the product) is determined by the lighting unit based on the determination result (CPU 11, program memory PG) and the determination result by the determination unit Control means (CPU11, program memory PG, exhibition status lighting control table LT1) for controlling lighting effects (brightness of light source, light color, lighting method, lighting range) on the product.

  Next, the operation concept of the inventory management device 1 (lighting control device) in the first embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. Further, it is possible to sequentially execute the operation according to the above-described program code transmitted via a transmission medium such as a network. In other words, in addition to the recording medium, an operation unique to the present embodiment can be executed using a program / data supplied externally via a transmission medium.

7 to 9 are flowcharts for explaining the operation (characteristic operation of the present embodiment) of the inventory management apparatus 1 that starts executing in response to power-on.
First, the CPU 11 of the inventory management device 1 clears the memory and the like in response to a power-on operation, and at the same time, the light source adjustment unit 53, the illumination range adjustment unit 54, the illumination direction adjustment unit 55, and the illumination method adjustment unit 56 of each lighting fixture 5. Are controlled so that the brightness, light color, illumination range, and illumination method of each luminaire 5 are set to an initial state (normal illumination state) (step A1 in FIG. 7). In this normal illumination state, for example, illumination is performed such that illumination light diffuses throughout the shelf due to daylight color.

  In this state, the inventory management device 1 checks whether or not the accounting (settlement) completion notification transmitted from the ECR 3 at the end of registration of one transaction (settlement) is received (step A2), or the product from the handy terminal 2 It is checked whether or not a replenishment notification indicating that the replenishment has been completed is received (step A4), or it is checked whether it is the control timing of the effect lighting (step A5), and if none of them (steps A2, A4, A5) NO), the process proceeds to step A6, and after other processing (such as on / off control of the lighting fixture 5) is performed, the process returns to the above-described step A2.

  Now, when a notice of accounting (settlement) completion is received from ECR3 (YES in step A2), based on the product data (number of sales for each product) received from ECR3, the inventory management table ST corresponding to the product is stored. When an update process for subtracting the “stock quantity” is performed (step A3) and the product data supplemented from the handy terminal 2 is received (YES in step A4), the “stock quantity” in the stock management table ST corresponding to the product code is received. Is updated (step A3). In addition, if it is the control timing of the effect lighting, that is, when it is detected that a predetermined time (for example, 30 seconds) has passed based on the timing information from the clock unit 16 (YES in step A5), The process moves to controlling the effect lighting.

  First, in order to sequentially specify each item in the store, one item in the inventory management table ST is specified (step A7), and it is checked whether all items have been specified (step A8). Is designated (NO in step A8), the display status illumination control table LT1, the specific product illumination control table LT2, and the sales trend illumination control table LT3 are referred to based on the designated product, and the designated product is subjected to illumination control. It is checked whether the product is a target product (step A10). That is, it is checked whether the “product code” of the designated product is set in any of the lighting control tables LT1, LT2, and LT3.

  Here, if the “product code” of the designated product is not set in any of the tables LT1, LT2, and LT3 (NO in step A10), it is determined that the designated product is a product that is not subject to lighting control. Returning to step A7 to designate the next product, but if it is set in any of the tables LT1, LT2, LT3 (YES in step A10), it is determined that the product is subject to lighting control, and the next Moving to Step A11, the shelf position corresponding to the designated product is specified, and the lighting fixture 5 corresponding to the shelf position is specified. In this case, with reference to the inventory management table ST, the “shelf position number” and “lighting fixture number” corresponding to the “product code” are read to identify the shelf position and the lighting fixture 5 corresponding to the designated product. And it moves to the flow of FIG. 8, FIG. 9, and the process which controls effect illumination is performed (step A12-A31).

  First, the inventory management device 1 checks whether the target product (designated product code) for lighting control is set in the exhibition status lighting control table LT1 (step A12 in FIG. 8), and if it is set (step A12). YES), it is checked whether or not “item quantity” is set in the “exhibition status” item (step A13). If “product inventory quantity” is set (YES in step A13), the inventory management table ST is referred to (step A14), and the “inventory quantity” is read, and “inventory quantity” is less than the limit value. A check is made (step A15).

  Here, if the “stock quantity” is less than the limit value (YES in step A15), “lighting control information for the product inventory quantity (less than the limit value) (lighting control information for clerk appeal) from the display status lighting control table LT1. Is transmitted to the lighting fixture 5 identified in step A11 described above (step A16) If the “stock quantity” is equal to or greater than the limit value (NO in step A15), the exhibition status lighting control table LT1. Reads out the lighting control information (lighting control information for customer appeal) corresponding to the product inventory quantity (more than the limit value) and transmits it to the specified lighting fixture 5 (step A17). Returning to A7, the next product is designated.

  In addition, when “product reduction degree” is set in the “exhibition status” item (NO in step A13), a shooting instruction is given to the lighting fixture 5 specified in step A11 described above, and responds to it. When the captured image transmitted from the lighting fixture 5 is received and acquired (step A18), by analyzing the captured image, a blank space other than the space where the product is arranged at the shelf position is detected, and the entire shelf position is detected. The ratio of the blank space to is specified as the reduction degree of the product (step A19). Then, it is checked whether or not the degree of decrease is not less than a limit value (for example, not less than 80%) (step A20).

  Here, if the decrease degree is equal to or greater than the limit value (YES in step A20), the illumination control information corresponding to the “product decrease degree (greater than the limit value)” from the display status lighting control table LT1 (lighting control information for clerk appeal) ) Is read out and transmitted to the specified luminaire 5 (step A16). If the degree of decrease is less than the limit value (NO in step A20), the illumination control information (lighting control information for customer appeal) corresponding to the “product decrease degree (less than the limit value)” from the exhibition status lighting control table LT1. Is transmitted to the specified lighting fixture 5 (step A17). Then, it returns to step A7 of FIG. 7, and designates the next goods.

  On the other hand, if the target product for lighting control (designated product code) is not set in the exhibition status lighting control table LT1 (NO in step A12), the flow proceeds to the flow of FIG. 9, and the target product for lighting control is specified product lighting control. It is checked whether it is set in the table LT2 (step A21). If the designated product is a specific product (YES in step A21), it is checked whether the specific product is a special sale item (step A22). If the designated product is a special sale item (YES in step A22), the clock 16 counts time. It is checked whether the information corresponds to a special sale time zone (step A23). Here, if it is not the special sale time zone (NO in step A23), the process returns to step A7 in FIG. 7 to specify the next product, but if it is the special sale time zone (YES in step A23), the specific product illumination control table. The lighting control information corresponding to “sale item (time zone)” is read with reference to LT2 and transmitted to the lighting fixture 5 identified in step A11 described above (step A24). Then, it returns to step A7 of FIG. 7, and designates the next goods.

  If the specific product is not a special sale item (YES in step A22), that is, if it is a recommended product, the process proceeds to step A25 to check whether the timekeeping information of the clock unit 16 corresponds to the recommended date. If it is not the recommended date (NO in step A25), the process returns to step A7 in FIG. 7 to specify the next product. If it is the recommended date (YES in step A25), refer to the specific product lighting control table LT2. The lighting control information corresponding to “recommended product (date)” is read out and transmitted to the lighting fixture 5 identified in step A11 described above (step A24). Then, it returns to step A7 of FIG. 7, and designates the next goods.

  On the other hand, if the target product for lighting control (designated product code) is not set in the specific product lighting control table LT2 (NO in step A21), it is determined that it is set in the sales trend lighting control table LT3. Moving to A27, if the sales trend is in the time zone (YES in step A27), it is checked whether the timekeeping information of the clock unit 16 corresponds to a time zone in which it can be sold well (step A28). If it is not the corresponding time zone (NO in step A28), the process returns to step A7 in FIG. 7 to specify the next product, but if it is the applicable time zone (YES in step A28), the sales trend illumination The illumination control information corresponding to the “time zone” is read with reference to the control table LT3, and transmitted to the luminaire 5 identified in step A11 described above (step A24). Then, it returns to step A7 of FIG.

  If the sales trend is not in the time zone (NO in step A27), it is determined that the sales trend is a date, and it is checked whether the timekeeping information of the clock unit 16 corresponds to a good selling date (step A30). Here, if it is not the relevant date (NO in step A30), the process returns to step A7 in FIG. 7 to specify the next product, but if it is the relevant date (YES in step A30), the sales trend lighting control table. With reference to LT3, the illumination control information corresponding to the “date” is read out and transmitted to the luminaire 5 identified in step A11 described above (step A31). Then, it returns to step A7 of FIG. Hereinafter, the above-described operation (steps A7 to A31) is repeated until all the products are designated (YES in step A8 in FIG. 7). Here, when all the products have been designated (YES in step A8), the process returns to step A2.

  On the other hand, when receiving the shooting instruction from the inventory management device 1, the lighting fixture 5 activates the camera unit 58 and transmits an image of the product (entire shelf position) to the inventory management device 1 together with its own lighting fixture number. Further, when illumination control information (light source brightness, light color, illumination method, illumination range) is received from the inventory management device 1, the light source adjustment unit 53, illumination range adjustment unit 54, illumination method adjustment based on the illumination control information. The unit 56 is driven to adjust the light source brightness, light color adjustment, illumination method, and illumination range adjustment. Hereinafter, the inventory management apparatus 1 adjusts the brightness of the light source, the light color, the illumination method, and the illumination range each time by repeating the above operation every time the control timing of the effect lighting is reached.

  As described above, in the first embodiment, the inventory management apparatus 1 determines the display status of products displayed in the store, and controls the lighting effect on the products by the lighting fixture 5 based on the determination result. Since it did in this way, the appropriate lighting suitable for the display condition of goods can be implement | achieved in a shop, without performing special operation for lighting control. For example, when the number of products is small, lighting is performed for the store clerk appeal to encourage the store clerk to replenish the product, and when the number of products is large, the customer's attention and purchasing motivation is encouraged. Lighting effects for customer appeal can be performed, which is advantageous for store operation and sales promotion.

  Since the inventory management device 1 determines the display status of the product by referring to the product data indicating the number of stocks corresponding to the product displayed in the store, the lighting management is performed according to the actual sales. It is possible to control the production, and it is possible to appeal the selling item to other customers.

  Since the inventory management device 1 identifies the degree of reduction of the product by analyzing an image obtained by photographing the product displayed in the store, and determines the display status of the product based on the degree of reduction, Lighting effects according to the actual state in which products are displayed at the shelf positions are possible. For example, even if the number of products is more than the limit, even if a large blank space is born, lighting effects for clerk appeal are performed on the shelf position, so the clerk can rearrange and replenish the product. Can be done instantly.

  The inventory management device 1 controls the lighting effect as an appealing product to the customer if there are many products displayed when controlling the lighting effect on the product based on the display status of the product. By changing the expression of the lighting, it is possible to encourage the customer's attention and motivation to purchase, and it is possible to appeal the selling products to other customers.

  The inventory management device 1 controls the lighting effect as an appealing product to the store clerk if the number of products displayed when the lighting effect on the product is controlled based on the display status of the product is small. It is possible to accurately notify the shortage of inventory simply by changing the expression of lighting.

  Since the inventory management device 1 determines whether or not it corresponds to the sales trend of the product displayed in the store, and controls the lighting effect on the product based on this sales trend, Therefore, it is possible to realize appropriate lighting according to the sales trend of the product without performing a special operation. For example, for products that sell well depending on the time of day and day of the week, it is possible to appeal to customers that they are selling products on that day and day of the week. If you want to appeal to customers, it will help promote the product.

  The inventory management device 1 determines whether or not the product is a specific product, and controls the lighting effect on the product based on the determination result. Lighting for customer appeal can be performed in order to encourage customers' attention and purchasing motivation for recommended items, which is advantageous for store management and sales promotion.

  The inventory management apparatus 1 can control the lighting effect on the product by associating the product with the shelf position and specifying the replacement shelf position even if the product is replaced.

  Since the luminaire 5 has an adjustment function that changes any one of the brightness, light color, illumination range, illumination direction, and illumination method of the light source, a variety of illumination effects are possible.

  In the above-described first embodiment, the multi-stage product display shelf 6 is illustrated, but the present invention is not limited to the product shelf but may be a case where various products are stored and arranged in a wagon (loading platform) or the like. Good. In this case, the lighting fixture 5 should just be arrange | positioned for every wagon.

  In the first embodiment described above, the case where the lighting control device is applied to the inventory management device 1 has been described. However, the lighting control device may be applied to the handy terminal 2 and the ECR 3. Furthermore, the lighting control device is not limited to the order control device 1, the handy terminal 2, and the ECR 3, but may be a dedicated device or the lighting fixture 5 itself.

  In the above-described first embodiment, the lighting fixtures 5 are associated with the products (shelf positions) in a one-to-one manner to perform lighting effects. A plurality of lighting fixtures 5 may be arranged on the screen. In this case, a finer illumination effect can be achieved by controlling the illumination effect by the plurality of lighting fixtures 5. Moreover, a plurality of light sources may be provided in one lighting fixture 5 and the lighting effect may be performed by selectively controlling the plurality of light sources.

(Second Embodiment)
The second embodiment of the present invention will be described below with reference to FIGS.
In the above-described first embodiment, the case where the present invention is applied to lighting effects on merchandise in a retail store is exemplified. However, in the second embodiment, the present invention is applied to lighting effects on a dining table in a restaurant or the like. This is the case. In this case, in 2nd Embodiment, the illuminating device 5 discriminate | determines the change condition of the dining table in a shop, and controls the lighting effect to a dining table based on the discrimination | determination result. Here, in both the embodiments, the same or the same names are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

FIG. 10 is a diagram for explaining the relationship between the lighting fixture 5, the handy terminal 7, and the dining table in the second embodiment.
In a restaurant, a handy terminal (portable terminal device: order terminal) 7 that is held by a customer service representative and inputs the order data, the number of customers, etc. for each table (each transaction) is not shown, but the order data entered is not shown. Is transmitted to the ECR 3 or transmitted to an order management apparatus (not shown) for storing and managing order data. Furthermore, when the handy terminal 2 inputs the order data to a new customer, the handy terminal 2 transmits a photographing instruction to the lighting fixture 5 or transmits customer number data via the wireless LAN communication. In addition, since the lighting fixture 5 has the structure similar to FIG. 6, the structure is abbreviate | omitted illustration. The components of the handy terminal 7 are basically the same as those of the inventory management apparatus 1 of FIG.

  The luminaire 5 is arranged in association with the dining table, is a lighting fixture for illuminating the dining table from above, and has an illumination adjustment function and a camera function (imaging function). In this case, as the number of lighting fixtures 5 corresponding to the number of seats on the ceiling portion of the dining table, for example, four lighting fixtures 5 (one per person) are arranged in a four-seat dining table. For example, the luminaire 5 performs spot illumination on the table surface, performs spot illumination on the seat portion of the table, or performs diffuse illumination on the entire periphery including the table.

  When the lighting fixture 5 receives a shooting instruction from the handy terminal 7, it starts a shooting operation. And the lighting fixture 5 acquires the image which image | photographed the corresponding table surface, and discriminate | determines as a change state of a table whether the first order goods were arranged on the table surface while analyzing the captured image, Whether or not a predetermined time has passed since the first ordered item is served is determined as a change state of the table. Here, the predetermined time is an average required time (eating and drinking time) from the first serving to the completion of eating and drinking, for example, 40 minutes for a course meal, and is arbitrarily set by a user operation. It has been done.

  In this case, the lighting fixture 5 is the state before the first ordered item is served as the state of progress (transition state) of eating and drinking, “before the eating and drinking”, and before the predetermined time has elapsed after the first ordered item is served. Is recognized as “a state during eating and drinking”, and after a predetermined time has passed, as “a state after eating and drinking”, and lighting effects on the table are controlled in accordance with each transition state. In addition to determining whether or not a person is eating or drinking as the change state of the table as described above, the lighting fixture 5 also determines the number of customers sitting on the table as the change state of the table, and the table according to the number of guests. The lighting production is controlled. Here, whether to control the lighting effect according to the changing state of the table or to control the lighting effect according to the number of customers can be arbitrarily selected and set by a user operation. Further, the lighting effect on the table means not only the case where the corresponding customer's table is illuminated, but also the case where the customer's surroundings are illuminated.

FIG. 11 is a diagram for explaining the transition state lighting control table LT4 and the number of people lighting control table LT5 in the lighting control database DB provided in the lighting fixture 5.
The transition state lighting control table LT4 stores control information for lighting effects corresponding to “state before eating”, “state during eating” and “state after eating”. As shown in FIG. 5, the items include “transition state”, “brightness of light source”, “light color”, “illumination method”, and “illumination range”. FIG. 11 (3) is a diagram showing a table surface illumination state a, a table illumination state b, a table surface and a table illumination state c as illumination states obtained by controlling the illumination range and the like.

  In the transition state lighting control table LT4, the control information for lighting effects corresponding to the “state before eating and drinking” corresponding to the “state before eating and drinking”, for example, the lighting state b of the passenger seat by the daylight color with reduced overall brightness is provided. Is set. Corresponding to the “state after eating and drinking”, the control information for lighting effect that is set to the lighting state “a” on the table surface is set by the color of the light bulb whose overall brightness is increased. Thus, control information for lighting effects is set in which the lighting state c of the dining table and the audience seats is set by daylight color with reduced overall brightness. In particular, in the “drinking state”, the colors of dishes (strong reddish colors such as tuna) can be expressed more vividly, and vegetables can be produced with natural colors to make them look delicious. I try to stand up. Thus, the lighting method (relationship between cooking and light color, brightness, etc.) for producing the dish so that it looks delicious can be arbitrarily set according to the intention of the store.

  The number-of-persons lighting control table LT5 stores control information for lighting effects corresponding to the number of customers sitting on the table. As shown in FIG. 11 (2), “table number” and “brightness of light source”. , “Light color”, “illumination method”, and “illumination range”. In the number-of-persons lighting control table LT5, if “the number of people at the table” is “1”, the control information for lighting effect that becomes the lighting state a of the table surface is set, and if “2-4 people”, Control information for lighting effects that is set to the lighting state c of the table and the audience seat is set. If “5 or more”, control information for lighting effects that is set to the lighting state b of the seat is set.

FIG. 12 is a flowchart showing the operation of the handy terminal 7 in the second embodiment.
First, the handy terminal 7 checks whether or not an operation for inputting order data has been performed (step B1). As other operations, an operation for inputting the number of customers and the seat position is performed, or an operation for inputting a table number is performed. If it is performed (NO in step B1), the number of customers and seat position input processing, table number input processing, etc. are performed as processing corresponding to the operation (step B2), but when order input operation is performed (step B2) (YES in B1), the inputted order data is transmitted to ECR3 or the like and registered (step B3). And after specifying the corresponding lighting fixture 5 as a control object of a lighting effect based on the inputted table number, the number of customers and the seat position (step B4), a shooting instruction is transmitted to the specified lighting fixture 5 (step S4). B5), the number of people is transmitted (step B6). Then, it returns to step B1.

FIG. 13 is a flowchart showing the operation of the lighting fixture 5 in the second embodiment, and the execution is started in response to power-on.
First, the lighting fixture 5 controls the light source adjustment part 53, the illumination range adjustment part 54, the illumination direction adjustment part 55, and the illumination method adjustment part 56, and the brightness, light color, illumination range, and illumination method of each illumination fixture 5. Is set to an initial state (normal illumination state) (step C1). In this normal lighting state, for example, the lighting state c of the table surface and the passenger seat is set by daylight color. In this state, it is checked whether a shooting instruction has been received from the handy terminal 7, that is, whether an order input operation for a new customer has been performed on the handy terminal 7 side (step C2). When it is received (YES in step C2), it is checked whether the lighting effect is set to be controlled according to the transition state (step C3).

  If it is preset by the user operation to control the lighting effect according to the number of customers (NO in step C3), the process proceeds to a process for controlling the lighting effect according to the number of customers (step C4). In other words, if the number of guests is “1”, the lighting effect is the lighting state a of the table surface, and if “2-4 people”, the lighting effect is the lighting state c of the table surface and the audience seat, If it is “5 or more”, the lighting effect of the passenger seat lighting state b is performed. If the lighting effect is controlled in accordance with the transition state by a user operation (YES in step C3). ), And shifts to a process of controlling the lighting effect according to the transition state (steps C5 to C17).

  In other words, the meal flag (not shown) indicating the transition state is turned off (step C5), and an illumination effect is set to the illumination state b of the passenger seat as illumination according to the “state before eating and drinking” (step C6). Then, the camera unit 58 is activated to start a photographing operation (step C7), and a timer (not shown) measurement operation is started (step C8). Then, while analyzing the photographed image (step C9), it is checked whether an order item has appeared in the image, that is, whether the first arrangement is detected (step C10). If the first arrangement is not detected (in step C10). NO), whether or not the during-meal flag is “on” is checked (step C11). Since the pre-meal state is now “off” (NO in step C11), step C9 The process waits for the first serving while analyzing the captured image.

  Here, when the first arrangement is detected (YES in step C10), the meal flag is turned on (step C12), and the illumination state a on the table surface is used as the illumination corresponding to the “drinking state”. An illumination effect is performed (step C13). Then, after stopping the shooting operation (step C14), it is checked whether the timer has timed out, that is, whether a predetermined time has passed since the first serving was detected (whether eating or drinking has been completed) (step C15), It will be in a standby state until this predetermined time passes. Here, when the passage of a predetermined time is detected (YES in step C11), an illumination effect is obtained in which the lighting state corresponding to the table surface and the passenger seat illumination state c is provided as illumination according to the “state after eating and drinking” (step C16). Then, after stopping the measurement operation of the timer and clearing the measurement value (step C17), the process returns to step C2 and waits for a shooting instruction. Thereafter, the above-described operation is repeated every time a shooting instruction is received.

  As described above, in the second embodiment, the lighting fixture 5 discriminates the change status of the table in the store, and controls the lighting effect on the table based on the discrimination result. Therefore, it is possible to realize appropriate lighting suitable for the changing situation of the table without performing any special operation.

  Since the lighting fixture 5 discriminate | determines the condition of the order goods arranged on the table as a change condition of the table, it can control the lighting production to the table according to the arrangement of the order items.

  Since the lighting fixture 5 discriminate | determines the state during eating and drinking and the state other than that as the change state of the table, it discriminate | determines that it is in the state of eating and drinking as a turning point that the first order goods were arranged. Can do. This makes it possible to illuminate the table brightly during eating and drinking, and illuminate the audience seats in other states.

  Since the lighting fixture 5 discriminate | determines the change condition of the table by analyzing the image which image | photographed the table, the change can be discriminate | determined appropriately.

  Since the lighting fixture 5 discriminate | determines the number of guests seated on the seat of the dining table as the change state of the dining table, the lighting effect to the dining table can be controlled according to the number of guests. For example, when there are a large number of people, the audience seats can be brightly illuminated so that the conversation is bounced, and in the case of a single customer, the dining table can be illuminated brightly and the audience seats can be illuminated darkly.

  The luminaire 5 has an adjustment function that can change any one of the brightness, light color, illumination range, illumination direction, and illumination method of the light source, and controls lighting effects on the dining table based on the changing situation of the dining table. As a result, a variety of lighting effects are possible.

  In the second embodiment described above, when a predetermined time has elapsed since the first ordered item is served, it is determined that the state has been after eating or drinking. You may make it discriminate | determine that it is during eating and drinking (for example, coffee, tea arrangement).

  In 2nd Embodiment mentioned above, although the case where it applied to the lighting fixture 5 as an illumination control apparatus was shown, you may make it apply to the handy terminal 2 and ECR3. Furthermore, the lighting control device is not limited to the order control device 1, the handy terminal 2, and the ECR 3, but may be a dedicated device.

  Further, the “apparatus” and “unit” shown in each of the above-described embodiments may be separated into a plurality of cases by function, and are not limited to a single case. In addition, each step described in the above-described flowchart is not limited to time-series processing, and a plurality of steps may be processed in parallel or separately.
