In FIG. 3, the method for acquiring external temperature data in the designated period will be described by taking as an example a case where a period from time T11 to T52 from when the designated product 10A is processed until it is sold to the consumer is designated.

  The designated product 10A passes through the gate 511 at the entrance of the factory 41F, which is a food processing factory, and is processed in a low-temperature environment, and then is carried out to the external area 46F through the gate 512 at the truck entrance of the factory 41F. The Then, the designated product 10A is carried into the first truck 42F via the gate 521 at the entrance of the first truck 42F. The gate 521 at the entrance of the first truck 42F is a virtual gate whose position is selected by the portable terminal device. The designated product 10A passes through the gate 531 at the entrance of the distribution center 43F while being loaded in the first truck 42F. For this reason, the gate 531 also serves as the gate 522 at the exit of the first track 42F. The designated product 10A is unloaded from the first truck 42F in the first unloading area 43A, and then stored in the warehouse 43B through the gate 531a at the entrance of the warehouse 43B. At the time of shipment, the designated product 10A passes through the gate 531b at the exit of the warehouse 43B, is transported to the second unloading area 43C and loaded on the second truck 44F, and then the second truck 44F and the outlet of the distribution center 43F. And then delivered to the store 45F. The designated product 10A is carried out from the second track 44F in the external area 47F. The gate 542 corresponding to the exit of the second track 44F is a virtual gate whose position is selected by the portable terminal device. The designated product 10A is stored in the store warehouse 45A through the gate 551 at the entrance of the store 45F, and then displayed on the showcase 45B via the gate 551a at the exit of the store warehouse 45A. It passes to the consumer via the 45B gate 552 with the identification medium 30A attached.

  Among the plurality of areas where the designated goods move, the temperature sensors 61, 62, 63A to 63C, 64, 65A, and the like are disposed inside the factory 41F, the first truck 42F, the distribution center 43F, the second truck 44F, and the store 45F. 65B is installed, and the temperature sensors 61, 62, 63A to 63C, 64, 65A, and 65B output the detected temperatures inside each area to the servers 41S to 44S as time-series temperature data. In FIG. 3, the factory data D41 detected by the temperature sensor 61 of the factory 41F, the first track data D42 detected by the temperature sensor 62 of the first truck 42F, and the temperature sensor 63A of the first unloading area 43A in the distribution center 43F Detected first cargo handling area data D43A, warehouse data D43B detected by temperature sensor 63B of warehouse 43B, second cargo handling area data D43C detected by temperature sensor 63C of second cargo handling area 43C, temperature of second truck 44F The second track data D44 detected by the sensor 64, the store warehouse data D45A detected by the temperature sensor 65A of the store warehouse 45A in the store 45F, and the showcase data D45B detected by the temperature sensor 65B of the showcase 45B are schematically shown. ing. Each of these temperature data is stored almost in real time in the external temperature data group 72 of the database 70 by the servers 41S to 44S.

  The calculation parameter acquisition unit 26 refers to temperature data groups of a plurality of areas to which the designated product 10A has moved in order to obtain external temperature data of the designated product 10A. In the example of FIG. 3, the calculation parameter acquisition unit 26 uses the temperature sensor 61 for each temperature data of the factory 41F, the first truck 42F, the distribution center 43F, the second truck 44F, and the store 45F where the temperature sensors are installed. , 62, 63A to 63C, 64, 65A, 65B detected factory data D41, first track data D42, first cargo area data D43A, warehouse data D43B, second cargo area data D43C, Reference is made to the 2-track data D44, in-store warehouse data D45A, and showcase data D45B. The calculation parameter acquisition unit 26 refers to the outside air temperature data D81 of the external device 80 for the temperature data of the external areas 46F and 47F where the temperature sensor is not installed among the plurality of areas where the designated product 10A has moved. .

  In step S2 or step S8 in FIG. 2, the calculation parameter acquisition unit 26 reads the identification information as the position data of the designated product 10A at each date and time in the designated period. 531 (522), 531a, 531b, 532 (541), 542, 551, 551a, 552 position data G511, G512, G521, G531 (G522), G531a, G531b, G532 (G541), G542, G551, G551a , G552. The calculation parameter acquisition unit 26, based on the position data of the designated product 10A and the time information associated with the position data, of each area where the designated product 10A has moved from the plurality of temperature data referred to. The temperature data is extracted according to the stay time of the designated product 10A in each area.

  Specifically, the designated product 10A stays in the factory 41F from the first time T11 to the time T12 during the designated period of time T11 to T52. For this reason, the calculation parameter acquisition unit 26 extracts the temperature data of the period of time T11 to T12 from the factory data D41 of the factory 41F for the period of time T11 to T12 (see arrow Y11).

  In the next time period T12 to T21, the designated product 10A stays in the external area 46F. Therefore, for example, the calculation parameter acquisition unit 26 obtains temperature data for the time period T12 to T21 from the outside air temperature data D81 of the Japan Meteorological Agency. Extract (see arrow Y12). Further, if the external device 80 is a terminal device with a temperature sensor, the outside air temperature data D81 measured by the terminal device in the external area 46F may be used.

  And in the period of time T21-T22, since designated goods 10A is delivered by the 1st track | truck 42F, the parameter acquisition part 26 for a calculation acquires the temperature data of the period of time T21-T22 from the 1st track data D42. Extract (see arrow Y13). Subsequently, for the time T22 to T31a when the designated product 10A is unloaded in the first unloading area 43A, the calculation parameter acquisition unit 26 performs the temperature from the first unloading area data D43A to the period of time T22 to T31a. Data is extracted (see arrow Y14). The calculation parameter acquisition unit 26 extracts the temperature data of the period of time T31a to T31b from the warehouse data D43B for the period of time T31a to T31b in which the designated product 10A is stored in the warehouse 43B (see arrow Y15). For the period of time T31b to T32 when the product 10A moves to the second handling area 43C, temperature data for the period of time T31b to T32 is extracted from the second handling area data D43C (see arrow Y16).

  Thereafter, since the designated product 10A is delivered by the second track 44F during the period of time T32 to T42, the calculation parameter acquisition unit 26 extracts temperature data for the period of time T32 to T42 from the second track data D44. (See arrow Y17). And in the period of time T42-T51, since designated goods 10A stays in the external area 47F, the calculation parameter acquisition part 26 extracts the temperature data of the period of time T42-T51 from the outside temperature data D81 ( (See arrow Y18). Subsequently, since the designated product 10A is stored in the in-store warehouse 45A of the store 45F during the time T51 to T51a, the calculation parameter acquisition unit 26 detects the temperature during the period from the in-store warehouse data D45A to the time T51 to T51a. Data is extracted (see arrow Y19). And about the period of time T51a-T52 in which designated goods 10A were displayed in showcase 45B, the parameter acquisition part 26 for a calculation extracts the temperature data of the period of time T51a-T52 from showcase data D45B (arrow). Y20).

  The calculation parameter acquisition unit 26 acquires the external temperature data D71 of the designated product 10A in the designated time period T11 to T52 by combining the temperature data extracted as indicated by the arrows Y11 to Y20 in time series. To do.

  Here, when there is a difference between the product temperature and the external temperature, the amount of heat (J) flows into the product from the outside of the product as indicated by the arrow in FIG. When the product is packaged, the amount of heat (J) reaches the product itself via the package. When the amount of heat flows into the product, the temperature of the product itself changes according to the amount of heat that has flowed in and the specific heat capacity of the product.

  For example, FIG. 5 is a diagram showing a list Tj of specific heat capacities of strawberry, melon, and apple. The specific heat capacity shown in FIG. 5 indicates the amount of heat required to raise the temperature of 1 kg of the product by 1 ° C., and the unit is (kJ / kg · ° C.). Even if the product has the same product name, the specific heat capacity varies depending on the processing category and the difference in water content. Therefore, in FIG. 5, the specific heat capacity is classified into the product name, processing category, and water content. A value is associated.

  For example, when comparing raw strawberries, melons, and apples, the specific heat capacity decreases in the order of strawberries, melons, and apples, as shown in columns Tjs, Tjm, and Tja in FIG. FIG. 6 is a diagram showing the time dependence of temperature changes of raw strawberries, melons, and apples. The curve La in FIG. 6 shows the time dependency of the temperature change of the apple when the same amount of heat flows, and the curve Lm shows the time dependency of the temperature change of the melon when the same amount of heat flows. The curve Ls shows the time dependence of the temperature change of the strawberry when the same amount of heat flows. As shown in FIG. 6, when the same amount of heat flows, the temperature of the apple (curve La) is most likely to rise during the same observation time, and then the temperature of the melon (curve Lm) is likely to rise. Strawberries (curve Ls) have the lowest temperature. Thus, the temperature of the product changes according to the specific heat capacity of the product itself. As shown in FIG. 5, the specific heat capacity is stored in the specific heat capacity list data 74 in a state in which the specific heat capacity is associated with each configuration of the product such as the product type, product name, processing category, and moisture content.

  Since the product package member also passes through until the amount of heat flows into the product itself, in order to perform product temperature calculation processing, in addition to the external temperature data of the specified product and the specific heat capacity of the specified product, As a parameter for obtaining the magnitude of the amount of heat flowing, the thermal conductivity of the product and the package member is also required.

  For this reason, in step S5 of FIG. 2, the calculation parameter acquisition unit 26 uses the specific heat capacity corresponding to the type, product name, and configuration content of the designated product as the thermal characteristic data to be used for the product temperature calculation process, the product, The thermal conductivity of the package member is obtained. In the example of the configuration in FIG. 1, the thermal conductivity list data 73 and the specific heat capacity list data 74 are stored in the database 70 in advance. Based on the identification information of the designated product for which the calculation of the product temperature is instructed from the product list data 71, the calculation parameter acquisition unit 26, the product package information, the designated product type, the product name, the processing category, the moisture The designated product information indicating the detailed configuration of the product such as the content is acquired. Then, the calculation parameter acquisition unit 26 acquires the thermal conductivity corresponding to the product type and package type of the designated product from the thermal conductivity list data 73 based on the obtained designated product information, and the designated product. The specific heat capacity value corresponding to the configuration is acquired from the specific heat capacity list data 74.

  The product temperature calculation unit 27 obtains the amount of heat flowing into the product itself using at least the external temperature data of the product and the thermal conductivity of the product or package, and calculates the magnitude of the calculated heat amount and the specific heat capacity of the product itself. Based on the above, the product temperature is calculated by estimating the temperature change of the product itself.

  As an example of the calculation process, first, the product temperature calculation unit 27 uses at least the external temperature data of the product, and the thermal conductivity of the product or package, and the calculation target date and time of the previous calculation process and the current calculation target. The amount of heat that flows into the product itself between the date and time of is calculated. Then, the product temperature calculation unit 27 calculates the value of the temperature change from the product temperature of the previous calculation target date and time based on the calculated amount of heat and the specific heat capacity of the product itself. Then, the product temperature calculation unit 27 acquires the product temperature at the current calculation target date and time by adding the obtained temperature change value to the product temperature calculated once. Note that the product temperature calculation unit 27 may obtain and add the value of the temperature change based on at least the calculation prior to the current calculation process without using the previous calculation. In addition, the product temperature calculation unit 27 sets the external temperature of the area where the product first stayed as the initial value of the product temperature. For example, of the external temperature data of the factory 41F where this product is manufactured, the temperature corresponding to the date and time of manufacture of this product is set as the initial value of the product temperature of this product. In addition, the initial value of the product temperature is stored in the database 70 in correspondence with the type of product, and the product temperature calculation unit 27 stores the initial value corresponding to the type of product to be calculated from the database 70. May be obtained.

  For example, for the product temperature of the designated product 10A at times T11 to T22, the product temperature calculation unit 27 includes external temperature data D71a (see FIG. 7) of the designated product 10A at times T11 to T22 acquired by the calculation parameter acquisition unit 26. Product temperature data D74a of the designated product 10A at times T11 to T22 (FIG. 8) is performed by performing a calculation process for estimating the temperature change of the product itself based on the thermal conductivity of the product or package and the specific heat capacity of the product. Reference).

  As described above, in the first embodiment, the external temperature data D71a (see FIG. 7) simply obtained by tracing the external temperature data of the product is not acquired, but the thermal characteristic data of the product, The product temperature of this product is calculated based on the external temperature data that affects the time change of the product temperature. In other words, in the first embodiment, even when the external temperature of the designated product 10A suddenly changes due to the passage of the area boundary at times T12 and T21, the external temperature that has changed suddenly changes. The product temperature data D74a (see FIG. 8) that is closer to the temperature of the product itself is acquired by a calculation process by the product temperature calculation unit 27. Therefore, according to the first embodiment, the product temperature data D74a that is closer to the actual temperature of the product itself is used for product management, thereby enabling more accurate product temperature management.

  Further, in the first embodiment, as long as the position data of the designated product can be acquired, the management device 20 has the thermal characteristic parameters for calculation that are stored in advance and the temperature data of each area acquired through the network 90. In addition, the product temperature data can be acquired simply by performing a certain calculation process. For this reason, for the first embodiment, the identification medium 30 indicating only the identification information of the product 10 and the simple position data acquisition system including only the reading device that reads the identification medium 30 at the boundary of each area are applied as they are. be able to.

  In the product temperature management system 1 according to the first embodiment, as shown in FIG. 3, the designated product 10A is delivered to the consumer with the identification medium 30A attached. For this reason, the consumer himself / herself can read the identification information of the identification medium 30 </ b> A with a reading device, and request the product temperature data of the designated product 10 </ b> A from the management device 20 via the network 90. Accordingly, since the time series data D74p of the product temperature transmitted from the management device 20 can be directly displayed and output on the display Pa used by the consumer, the consumer himself / herself has the product temperature of the product actually purchased. You can check the history.

  In the first embodiment, when the designated article stays in the area where the temperature sensor is not installed among the plurality of areas, the input processing unit 22 or the communication processing unit 23 When the outside air temperature data 81 is received from the external device 80, calculation instruction information for instructing calculation of the article temperature of the designated article may be input to the control unit 21.

(Embodiment 2)
Next, a second embodiment will be described. FIG. 9 is a block diagram illustrating an example of the configuration of the commodity temperature management system according to the second embodiment. As shown in FIG. 9, the product temperature management system 201 according to the second embodiment includes a management device 220. The management apparatus 220 includes a control unit 221 having the same function as the control unit 21 instead of the control unit 21 of FIG. The management apparatus 220 includes a calculation unit 224 that further includes a warning determination unit 228.

  When the warning determination unit 228 determines that the product temperature of the designated product calculated by the product temperature computation unit 27 exceeds a predetermined threshold temperature of the designated product, the warning determination unit 228 notifies the management department of the designated product of the designated product. A warning indicating that the product temperature has exceeded a predetermined threshold temperature of the designated product is notified. The predetermined threshold temperature is set for each type of product, and it is determined that it is not desirable to exceed this threshold temperature for product management.

  Further, in the product temperature management system 201, as a warning unit that outputs a warning notified from the warning determination unit 228, for example, a warning notified from the warning determination unit 228 at the entrance of the facility 41 to 44 that is the boundary of each area Warning sections 291, 292a, 292b, 293a, 293b, 294a, 294b are provided. The warning units 291, 292a, 292b, 293a, 293b, 294a, 294b are connected to the corresponding servers 41S to 44S. The warning units 291, 292 a, 292 b, 293 a, 293 b, 294 a, and 294 b are, for example, an alarm device that can output sound and a lighting device that can change the lighting state. Of course, the warning units 291, 292 a, 292 b, 293 a, 293 b, 294 a, and 294 b shown in FIG. 9 are merely examples, and terminal devices of each management department that can receive a warning mail from the management device 220 and portable to each administrator Then, the portable terminal device that can be moved may function as the warning unit.

  FIG. 10 is a flowchart illustrating a processing procedure of product temperature calculation processing that causes the management device 220 to calculate the temperature of the product. Steps S201 to S206 shown in FIG. 10 are steps S1 to S6 shown in FIG. Then, the warning determination unit 228 determines whether or not the product temperature of the designated product calculated by the product temperature calculation unit 27 in step S206 exceeds a predetermined threshold temperature set in advance for the designated product. (Step S207).

  When the warning determination unit 228 determines that the calculated product temperature of the designated product exceeds a predetermined threshold temperature set in advance for the designated product (step S207: Yes), the management department of the designated product A warning notification process for notifying a warning is performed (step S208). Specifically, as shown in the product temperature data D74a in FIG. 11, the calculated product temperature of the designated product 10A exceeds the threshold temperature Th set corresponding to the type of the designated product 10A at time T13. In such a case, a warning is notified to the servers 41S to 44S located closest to the designated product. Receiving the notification, the servers 41S to 44S perform warning processing such as warning output and blinking lighting on the warning part closest to the position of the designated product among the warning parts 291, 292a, 292b, 293a, 293b, 294a, and 294b. In this case, it is notified that the product temperature of the designated product exceeds a predetermined threshold temperature for the designated product, and prompts the administrator to confirm the management state of the designated product. Further, the servers 41S to 44S may display a warning mail on the forefront of the display of the terminal device or portable terminal device closest to the position of the designated product.

  When the warning determination unit 228 determines that the calculated product temperature of the designated product does not exceed a predetermined threshold temperature set in advance for the designated product (step S207: No), or a warning notification When the process (step S208) is completed, the process proceeds to step S209. Steps S209 to S211 in FIG. 10 are steps S7 to S9 shown in FIG.

  As described above, in the second embodiment, when the calculation result of the product temperature of the designated product exceeds the predetermined threshold temperature of the designated product, the warning notification process is performed to notify that effect. , The temperature control of the product can be stricter and the quality of the product in the distribution process can be kept high.

  In the second embodiment, the warning determination unit 228 has described the example in which the warning is notified at the time T13 at the timing when the product temperature of the specified product exceeds the threshold temperature of the product in FIG. As shown in FIG. 4, the calculated product temperature of the designated product 10A may notify a warning at time T14 after a predetermined time Tc has elapsed from time T13. Further, the warning determination unit 228 notifies the warning when the product temperature of the designated product exceeds the threshold temperature of the product, and the designated product 10 </ b> A receives the designated product based on the acquired position data of the designated product. When it is determined that the vehicle has moved off the predetermined regular route, or when it has not passed the gate after the scheduled passage time of each gate, a warning is sent to the servers 41S to 44S. The warning section near the designated product 10A may output a warning that the designated product 10A does not pass the regular route on time.

  In the first and second embodiments, it is sufficient that the product temperature for the designated product and period can be calculated. Therefore, each temperature data in the external temperature data group 72 does not need to be stored in real time, and is necessary for the calculation. It may be in a form where external temperature data of a certain part is supplemented. Moreover, although the example in which the temperature sensor is installed in each facility 41-44 was demonstrated, the external temperature data itself used for a calculation may be the outside air temperature data of the meteorological agency of an external organization, and via the network 90 etc. It may be supplemented temperature data.

  Further, in the first and second embodiments, the case where the management devices 20 and 220 manage the product temperature of a product that moves in a plurality of areas has been described. However, the management devices 20 and 220 do not have a plurality of areas but a single item. Of course, it is also possible to manage the product temperature of the products staying in this area as an area to be managed. In this case, in the management devices 20 and 220, in order to manage the temperature of the product staying in the management target area, the calculation parameter acquisition unit 26 acquires the thermal characteristic data regarding the product when the period is specified. At the same time, by extracting the temperature data for the specified period from the temperature data along the time series inside the area to be managed, external temperature data that affects the time change of the product temperature of the specified period is acquired. Then, the product temperature calculation unit 27 calculates the product temperature of the product based on the thermal characteristic data acquired by the calculation parameter acquisition unit 26 and the external temperature data.

  In the first and second embodiments, the temperature sensors 61 to 64 detect the temperature inside the facility at regular intervals, and each server detects the temperature inside the facility every time the temperature sensors 61 to 64 detect the temperature inside the facility. Although it has been described above that the internal temperature data is transmitted to the communication processing unit 23 of the management device 20, as another embodiment, the servers 41S to 44S are accumulated by a request from the communication processing unit 23 of the management device 20. The temperature data corresponding to the request from the communication processing unit 23 may be transmitted to the communication processing unit 23 from the temperature data.

  Alternatively, in response to a request from the communication processing unit 23 of the management device 20, the temperature sensors 61 to 64 detect the temperature via the servers 41 </ b> S to 44 </ b> S and transmit the detected temperature to the communication processing unit 23 of the management device 20. Also good.

  Furthermore, when the devices of the temperature sensors 61 to 64 have a communication function via the network 90, it is possible to directly transmit and receive with the communication processing unit 23 of the management apparatus 20 without passing through the servers 41S to 44S.
