Specific examples of information processing systems according to embodiments of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is intended to include all modifications within the scope and meaning equivalent to the claims.

<System Overview>
FIG. 1 is a schematic diagram showing a configuration example of an information processing system according to a first embodiment. The information processing system according to this embodiment is a system that can be used by a delivery company or the like that delivers packages that require temperature control, such as freezing or refrigeration. The information processing system is configured to include a terminal device 1 used by a delivery worker and a delivery container 3 that contains the packages. The information processing system according to this embodiment is a system that supports the temperature management of the delivery container 3 by the delivery worker by having the terminal device 1 of the delivery worker acquire temperature information inside the delivery container 3 and notify the delivery worker that, for example, the temperature inside the delivery container 3 has reached an appropriate temperature or deviated from the appropriate temperature.

The delivery container 3 in this embodiment is a container for delivering luggage that requires freezing or refrigeration, for example, by placing pre-cooled ice packs in a highly heat-retaining container to maintain the appropriate temperature. The delivery worker places ice packs that have been pre-cooled in, for example, a refrigerator or freezer, into the delivery container 3 and waits until the inside of the delivery container 3 reaches the appropriate temperature. After the inside has reached the appropriate temperature, the delivery worker places the luggage to be delivered in the delivery container 3, loads the delivery container 3 into a delivery vehicle, and heads to the delivery destination. It is desirable that the inside of the delivery container 3 be maintained within a predetermined appropriate temperature range from the time the delivery worker places the luggage in the delivery container 3 until it is removed at the delivery destination.

The delivery container 3 according to this embodiment is equipped with a sensor that measures the internal temperature and a wireless communication function for transmitting and receiving information to and from the terminal device 1. In addition to the sensor that measures the temperature, the delivery container 3 may be equipped with various other sensors, such as a sensor that detects the opening and closing of the delivery container 3, or a sensor that detects the acceleration applied to the delivery container 3. In this embodiment, the delivery container 3 measures the internal temperature at a predetermined interval and transmits the measurement result to the terminal device 1.

The terminal device 1 may be a general-purpose information processing device such as a smartphone or tablet terminal device. However, the terminal device 1 may not be a general-purpose information processing device, but may be an information processing device dedicated to the delivery business. The terminal device 1 is preferably a portable information processing device, but may be an information processing device fixed to a delivery vehicle, for example. In this embodiment, the terminal device 1 periodically acquires temperature information regarding the internal temperature measured by a sensor in the delivery container 3 by wirelessly communicating with the delivery container 3. The terminal device 1 performs processes such as prediction and determination of the internal temperature of the delivery container 3 based on the acquired temperature information, and notifies the delivery worker of these processing results.

In this embodiment, the terminal device 1 performs processes such as predicting and determining the temperature inside the delivery container 3, but this is not limited to the above, and for example, a remote server device may perform these processes. The terminal device 1 communicates with the server device via a network and transmits temperature information acquired from the delivery container 3 to the server device. The server device receives the temperature information from the terminal device 1, performs processes such as predicting and determining the temperature inside the delivery container 3, and transmits the results of these processes to the terminal device 1. The terminal device 1 can receive the results of the processes from the server device 1 and notify the delivery worker.

In addition, in this embodiment, the description is given assuming a case where the inside of the delivery container 3 is kept at a low temperature, so-called cold storage, but this is not limited to this. For example, when delivering cooked food, the technology according to this embodiment can also be applied to a case where the inside of the delivery container 3 is kept at room temperature or a high temperature, so-called heat retention. In the case of heat retention, for example, the inside of the delivery container 3 can be kept at an appropriate temperature by putting pre-heated heat-retaining material into the delivery container 3.

<Device Configuration>
2 is a block diagram showing an example of the configuration of the terminal device 1 according to the first embodiment. The terminal device 1 according to the present embodiment is configured to include a processing unit 11, a memory unit (storage) 12, a communication unit (transceiver) 13, a display unit 14, an operation unit 15, and a GPS (Global Positioning System) receiving unit 16. The terminal device 1 is a device carried and used by a delivery worker, and has a function of wirelessly communicating with the delivery container 3 by short-range wireless communication, for example. The terminal device 1 can be realized by installing a predetermined application program in a general-purpose information processing device such as a smartphone or a tablet terminal device.

The processing unit 11 is configured using an arithmetic processing device such as a CPU (Central Processing Unit) or an MPU (Micro-Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). The processing unit 11 reads and executes a program 12a stored in the memory unit 12 to perform various processes, such as acquiring information from the delivery container 3, such as the results of temperature measurements taken by a sensor, and notifying the delivery worker of the acquired information.

The storage unit 12 is configured using, for example, a non-volatile memory element such as a flash memory or a storage device such as a hard disk. The storage unit 12 stores various programs executed by the processing unit 11 and various data required for the processing of the processing unit 11. In this embodiment, the storage unit 12 stores the program 12a executed by the processing unit 11.

In this embodiment, the program (computer program, program product) 12a is distributed by a remote server device or the like, and the terminal device 1 acquires it through communication and stores it in the storage unit 12. However, the program 12a may be written to the storage unit 12, for example, during the manufacturing stage of the terminal device 1. For example, the terminal device 1 may read the program 12a recorded on a recording medium 99 such as a memory card or an optical disk and store it in the storage unit 12. For example, the program 12a may be read from the recording medium 99 by a writing device and written to the storage unit 12 of the terminal device 1. The program 12a may be provided in the form of distribution via a network, or in the form of being recorded on the recording medium 99.

The communication unit 13 performs short-range wireless communication with other devices, for example, via Bluetooth (registered trademark) or wireless LAN. In this embodiment, the delivery container 3 has a function for performing similar short-range wireless communication, and the communication unit 13 of the terminal device 1 can communicate with one or more delivery containers 3 that are within the communication range. The communication unit 13 transmits data provided by the processing unit 11 to other devices, and provides data received from other devices to the processing unit 11. Note that the terminal device 1 may further include a communication unit for communicating with a server device, etc., via a mobile phone communication network, wireless LAN, the Internet, etc., in addition to the communication unit 13 for performing short-range wireless communication with the delivery container 3.

The display unit 14 is configured using a liquid crystal display or the like, and displays various images, characters, etc. based on the processing of the processing unit 11. The operation unit 15 accepts user operations and notifies the processing unit 11 of the accepted operations. For example, the operation unit 15 accepts user operations through an input device such as a mechanical button or a touch panel provided on the surface of the display unit 14. Furthermore, for example, the operation unit 15 may be an input device such as a mouse and a keyboard, and these input devices may be configured to be removable from the terminal device 1.

The GPS receiver 16 receives radio waves transmitted from GPS satellites and provides information contained in the received radio waves to the processor 11. The processor 11 can perform processing to identify the position (e.g., latitude and longitude) of the terminal device 1 based on the information provided by the GPS receiver 16.

In addition, in the terminal device 1 according to this embodiment, the processing unit 11 reads and executes the program 12a stored in the memory unit 12, so that the information acquisition unit 11a, the temperature prediction unit 11b, the pattern determination unit 11c, the temperature determination unit 11d, the notification processing unit 11e, and the like are realized in the processing unit 11 as software-like functional units. The information acquisition unit 11a periodically and repeatedly communicates with one or more delivery containers 3 via the communication unit 13, and acquires various information such as the detection results of the sensor from the delivery container 3. In this embodiment, the information acquisition unit 11a acquires information regarding the internal temperature measured by the temperature sensor of the delivery container 3, for example, once per minute.

The temperature reaching prediction unit 11b performs processing to predict the minimum temperature (maximum temperature in the case of heat retention) that the temperature inside the delivery container 3 will reach, based on the temperature information acquired by the information acquisition unit 11a from the delivery container 3. In this embodiment, the temperature reaching prediction unit 11b calculates the rate of change (first derivative value) of the temperature inside the delivery container 3, based on the time-series temperature information acquired by the information acquisition unit 11a. The temperature reaching prediction unit 11b predicts the temperature to be reached based on the calculated temperature change rate.

The pattern determination unit 11c performs a process to determine which pattern of temperature change exists inside the delivery container 3. As will be described in detail later, the inventors of the present application have investigated temperature changes inside the delivery container 3 under various conditions and found that temperature change patterns can be broadly classified into two types. In this embodiment, the pattern determination unit 11c determines whether the pattern of temperature change in the delivery container 3 is the first pattern or the second pattern.

The temperature determination unit 11d determines whether the temperature of the delivery container 3 is within the appropriate temperature range, etc., based on the temperature information acquired by the information acquisition unit 11a, the reached temperature predicted by the reached temperature prediction unit 11b, and the pattern of temperature change determined by the pattern determination unit 11c. In this embodiment, different determination conditions are set according to the pattern of temperature change of the delivery container 3. The temperature determination unit 11d makes a determination using the conditions corresponding to the pattern determined by the pattern determination unit 11c.

The notification processing unit 11e performs a process of notifying the result of the judgment made by the temperature judgment unit 11d. For example, when the temperature inside the delivery container 3 falls within the appropriate temperature range, the notification processing unit 11e notifies the delivery worker that preparation is complete. Also, for example, when the temperature inside the delivery container 3 falls outside the appropriate temperature range, the notification processing unit 11e notifies the delivery worker that an abnormality has occurred. The notification processing unit 11e notifies the delivery worker by, for example, displaying a predetermined message on the display unit 14. The notification processing unit 11e may also notify the delivery worker by audio output from a speaker (not shown), or may notify the delivery worker by both message display and audio output. The notification processing unit 11e may also notify the delivery worker by displaying a predetermined color, such as red when it is determined that an abnormality has occurred, and green when it is predicted that the temperature will fall within the appropriate temperature range.

Figure 3 is a block diagram showing an example of the configuration of a delivery container 3 according to this embodiment. The delivery container 3 according to this embodiment includes a control unit (controller) 31, a memory unit (storage) 32, a communication unit (transceiver) 33, a temperature sensor 34, an opening/closing sensor 35, and an acceleration sensor 36. Note that Figure 3 shows the electronic functional units of the delivery container 3, and does not show the other functional units.

The control unit 31 performs various processes by controlling the operation of the electronic functional units equipped in the delivery container 3. The control unit 31 periodically samples the signals output by sensors such as the temperature sensor 34, the opening/closing sensor 35, and the acceleration sensor 36 to obtain the detection results of each sensor, and stores the obtained information in the memory unit 32. The control unit 31 periodically reads out the information stored in the memory unit 32, for example, and transmits it to the terminal device 1.

The storage unit 32 is configured using a non-volatile memory element such as a flash memory or an EEPROM (Electrically Erasable and Programmable Read Only Memory). The storage unit 32 stores information provided by the control unit 31, such as information related to the detection results of the temperature sensor 34, the opening/closing sensor 35, and the acceleration sensor 36. The communication unit 33 performs short-range wireless communication with other devices, such as Bluetooth or wireless LAN. In this embodiment, the communication unit 33 performs wireless communication with the communication unit 13 of the terminal device 1. The communication unit 33 transmits data provided by the control unit 31 to other devices, and provides data received from other devices to the control unit 31.

The temperature sensor 34 is provided inside the delivery container 3 and detects the temperature inside the delivery container 3. The temperature sensor 34 may be configured using, for example, a thermocouple, a thermistor, or a resistance temperature detector. The temperature sensor 34 outputs, for example, an electrical signal corresponding to the temperature inside the delivery container 3 to the control unit 31.

The opening/closing sensor 35 is a sensor that detects the opening and closing of the delivery container 3. The delivery container 3 is equipped with, for example, an openable lid or door, and the delivery worker opens and closes this lid or door when placing a package in the delivery container 3 and when removing a package placed in the delivery container 3. The opening/closing sensor 35 is configured using, for example, a switch that switches between blocking and conducting depending on whether the lid or door is opened or closed, and outputs a signal to the control unit 31 indicating whether the delivery container 3 is in an open or closed state.

The acceleration sensor 36 is disposed at an appropriate position on the delivery container 3 and detects the acceleration applied to the delivery container 3. The acceleration sensor 36 may be, for example, a piezoelectric, piezo-resistive, or capacitive sensor. The acceleration sensor 36 outputs an electrical signal to the control unit 31 in accordance with, for example, the acceleration applied to the delivery container 3.

The delivery container 3 according to this embodiment is equipped with at least a temperature sensor 34, and may not be equipped with an opening/closing sensor 35 or an acceleration sensor 36. The control unit 31 of the delivery container 3 according to this embodiment obtains the measurement results of the internal temperature by sampling the signal output by the temperature sensor 34 at a predetermined cycle (e.g., once per minute). The control unit 31 stores the obtained temperature information in the memory unit 32, and transmits this temperature information to the terminal device 1 at a predetermined cycle (e.g., once per minute, but does not need to coincide with the sampling cycle).

<Temperature change pattern>
As described above, the inventors of the present application have investigated temperature changes inside the delivery container 3 under various conditions and found that the temperature change patterns can be roughly classified into two types. Fig. 4 is a schematic diagram for explaining the temperature change patterns. Fig. 4 shows two graphs showing temperature changes inside the delivery container 3, with the horizontal axis representing time and the vertical axis representing temperature. The graph in Fig. 4(A) is a first temperature change pattern, and the graph in Fig. 4(B) is a second temperature change pattern.

In the first temperature change pattern, the temperature inside the delivery container 3 decreases rapidly after the cooling material is introduced and reaches the lowest temperature (approximately -6°C to -7°C in this example). After reaching the lowest temperature, the temperature inside the delivery container 3 begins to increase rapidly. In this embodiment, the phenomenon in which the temperature inside the delivery container 3 changes from a rapid decrease to a rapid increase is called an "overshoot," and the first temperature change pattern is a temperature change pattern that includes this overshoot. After the rapid increase in temperature due to the overshoot, the temperature inside the delivery container 3 gradually decreases in temperature increase rate and reaches a stable temperature with a small temperature increase rate. In the graph of FIG. 4(A), the temperature inside the delivery container 3 reaches a stable temperature of approximately 0°C after about 6 hours have passed after the overshoot. After that, the temperature inside the delivery container 3 gradually increases but is kept within the appropriate temperature range, and for example, the rate of temperature increase increases after the cooling material melts (after about 24 hours have passed in this example), and gradually increases to a temperature around room temperature.

In the second temperature change pattern, the temperature inside the delivery container 3 drops sharply after the cold pack is added and reaches the minimum temperature (approximately -19°C to -20°C in this example). After reaching the minimum temperature, the temperature inside the delivery container 3 gradually increases but does not show any overshoot phenomenon, and becomes a stable temperature with a small rate of temperature increase. In the graph of FIG. 4(B), after the temperature inside the delivery container 3 reaches the minimum temperature, the temperature change stabilizes around this minimum temperature. After that, the temperature inside the delivery container 3 gradually increases but is kept within the appropriate temperature range, and for example, after the cold pack melts (approximately 9 hours have passed in this example), the rate of temperature increase increases and the temperature gradually increases to about room temperature.

Whether the temperature change inside the delivery container 3 is the first temperature change pattern or the second temperature change pattern can be determined, for example, depending on whether the rate of temperature increase after the temperature reaches the minimum temperature due to a sudden temperature decrease after the introduction of ice packs or the like and the temperature change direction changes from decrease to increase exceeds a predetermined threshold. In other words, whether the temperature change inside the delivery container 3 includes an overshoot can be determined depending on whether the rate of temperature increase after the minimum temperature is reached exceeds a predetermined threshold.

The inventors' investigations and research have revealed that whether the temperature change inside the delivery container 3 is the first temperature change pattern or the second temperature change pattern is determined by factors such as the size (capacity) of the delivery container 3, the type of ice pack to be added, the number of ice packs to be added, and the temperature before the ice packs are added. In this embodiment, for example, before a delivery worker adds ice packs to the delivery container 3, the terminal device 1 inquires the delivery worker as to which temperature change pattern the ice packs are, and in response, the delivery worker inputs into the terminal device 1 which temperature change pattern the ice packs are based on his or her own experience, etc. The terminal device 1 can determine whether the ice packs are the first temperature change pattern or the second temperature change pattern based on the delivery worker's input, and perform subsequent processing such as temperature determination.

In addition, the terminal device 1 may inquire, for example, about the size of the delivery container 3 and the number of ice packs added, rather than directly inquiring of the delivery worker as to which temperature change pattern is present. The terminal device 1 pre-stores information, such as a table that associates information such as the size of the delivery container 3 and the number of ice packs added with temperature change patterns of the temperature inside the delivery container 3. The terminal device 1 can refer to the pre-stored table based on information such as the size of the delivery container 3 and the number of ice packs added input by the delivery address, and determine which temperature change pattern corresponds to this input information.

In addition, there may be cases where the delivery worker is unable or does not input the temperature change pattern or related information to the terminal device 1, for example, when the delivery worker is unable to judge the temperature change pattern in light of his or her own experience. In such cases, the terminal device 1 calculates the rate of temperature rise after the temperature inside the delivery container 3 reaches the minimum temperature based on the temperature acquired from the sensor in the delivery container 3, and determines the temperature change pattern depending on whether this rate of rise exceeds a predetermined threshold value.

<Prediction of reached temperature>
The terminal device 1 according to the present embodiment performs a process of predicting the minimum temperature (hereinafter referred to as the minimum temperature) that the temperature inside the delivery container 3 reaches after the cooling material is put in, regardless of whether the temperature change pattern inside the delivery container 3 is the first temperature change pattern or the second temperature change pattern. FIG. 5 is a schematic diagram for explaining the prediction of the minimum temperature. FIG. 5 shows a graph with the temperature [°C] inside the delivery container 3 on the vertical axis and the temperature change rate [°C/min] on the horizontal axis. In this embodiment, the temperature change rate is a difference value obtained by subtracting the temperature at a certain point from the temperature at the previous point, for the time-series temperature obtained by the temperature sensor 34 of the delivery container 3 periodically measuring the internal temperature. When the temperature change rate is a positive value, the temperature inside the delivery container 3 increases, and when the temperature change rate is a negative value, the temperature inside the delivery container 3 decreases.

In the illustrated example, immediately after the cold pack is added, the temperature inside the delivery container 3 drops sharply at a large rate of change (absolute value) of approximately -5°C/min. After that, the temperature change rate inside the delivery container 3 gradually decreases to approach 0°C/min, and finally reaches 0°C/min. The temperature when this temperature change rate reaches 0°C/min is the lowest temperature reached. As indicated by the arrows in Figure 5, except for the first few points, the rate of change of the temperature change rate (i.e., the second derivative of the temperature) is almost constant.

The terminal device 1 according to this embodiment starts a process to determine the temperature inside the delivery container 3 after, for example, a delivery worker puts ice packs into the delivery container 3, and periodically acquires temperature information from the delivery container 3, including the temperature measurement results from the temperature sensor 34. The terminal device 1 periodically and repeatedly acquires temperature information to acquire time-series temperature information, and calculates, for example, the difference between the temperature acquired this time and the temperature acquired immediately before as the rate of change of temperature (first derivative of temperature). Furthermore, the terminal device 1 calculates the difference between the rate of change calculated this time and the rate of change calculated last time as the rate of change of the rate of change (second derivative of temperature).

The terminal device 1 calculates the rate of change of the temperature of the delivery container 3 and the second derivative of the temperature, excluding, for example, the first few points of temperature information obtained from the delivery container 3. After calculating the second derivative of the temperature for several times, the terminal device 1 calculates, for example, the average value of these several second derivative values. Based on the temperature at that time, the rate of change of the temperature at that time, and the average value of the calculated second derivative values, the terminal device 1 can calculate the temperature of the delivery container 3 when the rate of change of the temperature becomes 0. The terminal device 1 can use the calculated temperature as a predicted value of the minimum temperature to be reached. In the example shown in FIG. 5, the minimum temperature to be reached can be predicted to be approximately -3°C.

The inventors of the present application have confirmed that the above-mentioned prediction of the minimum temperature to be reached is an effective method regardless of whether the temperature change pattern of the delivery container 3 is the first temperature change pattern or the second temperature change pattern. In this embodiment, the predicted value of the minimum temperature to be reached can be used, for example, to notify a delivery worker that there is a risk that the temperature of the delivery container 3 will not be within the appropriate temperature range.

In addition, in this embodiment, when the multiple time-series change rates calculated by the terminal device 1 continue to have a value of 0 or close to 0 for multiple consecutive times, it is determined that the temperature inside the delivery container 3 has reached a stable temperature. The temperature range and the number of consecutive times that serve as the criteria for determining a stable temperature are predetermined by the designer of the information processing system according to this embodiment, and are stored in advance in the terminal device 1.

<Temperature determination>
In the information processing system according to the present embodiment, a temperature range defined by a predetermined upper limit and lower limit is defined as an appropriate range, and the terminal device 1 determines whether the temperature inside the delivery container 3 is within this appropriate range, is not within the appropriate range, is within the appropriate range but is in danger of going outside the appropriate range, or has gone outside the appropriate range, and notifies the delivery worker of this. The upper limit and lower limit defining the appropriate range are input in advance, for example, by the delivery worker, and are stored as setting information in the memory unit 12 of the terminal device 1, for example. The appropriate range does not need to be defined by two values, the upper limit and the lower limit, and may be defined by, for example, only the upper limit or only the lower limit.

As described above, the temperature change pattern inside the delivery container 3 is either the first temperature change pattern or the second temperature change pattern. In the information processing system according to this embodiment, the terminal device 1 sets different temperature conditions for determining the temperature inside the delivery container 3 depending on whether the temperature change pattern is the first temperature change pattern or the second temperature change pattern.

Figures 6 to 8 are schematic diagrams showing an example of the relationship between temperature change inside the delivery container 3 and the appropriate temperature range. Figures 6 and 7 show an example of temperature change in a first temperature change pattern, and Figure 8 shows an example of temperature change in a second temperature change pattern. Each figure also shows three graphs showing the relationship between temperature change inside the delivery container 3 and the upper and lower limits of the appropriate temperature range. In each graph, the thick solid line indicates the temperature of the delivery container 3, the thin solid line indicates the upper limit, and the dashed line indicates the lower limit.

Figure 6 (a) shows a case where the minimum temperature reached inside the delivery container 3 is higher than the upper limit in the first temperature change pattern. In this case, the temperature inside the delivery container 3 does not fall within the appropriate temperature range. Therefore, when the terminal device 1 predicts that the minimum temperature reached is higher than the appropriate temperature range in the first temperature change pattern, it can notify the delivery worker that the temperature inside the delivery container 3 may not fall within the appropriate temperature range. In this case, the terminal device 1 may notify the delivery worker that, for example, the number of ice packs placed in the delivery container 3 may be insufficient, the type of ice packs may be inappropriate, or the ice packs may not be sufficiently cooled.

6(b) shows a case where the minimum temperature inside the delivery container 3 is within the appropriate range in the first temperature change pattern, but the stable temperature after the overshoot is higher than the upper limit. In this case, the temperature inside the delivery container 3 is within the appropriate temperature range for a short period of time, but is outside the appropriate temperature range after that, so the delivery worker cannot use this delivery container 3 for delivery work. Therefore, the terminal device 1 can notify the delivery worker that the temperature inside the delivery container 3 is outside the appropriate temperature range when the temperature inside the delivery container 3 increases and becomes higher than the upper limit after the temperature inside the delivery container 3 reaches the minimum temperature, or when the temperature inside the delivery container 3 becomes a stable temperature higher than the upper limit. In this case, the terminal device 1 may also notify the delivery worker that, for example, the number of ice packs put into the delivery container 3 may be insufficient, the type of ice packs may be inappropriate, or the ice packs may not be sufficiently cooled.

Figure 6 (c) shows a case in which, in the first temperature change pattern, the minimum temperature reached inside the delivery container 3 is within the appropriate range, and the stable temperature after the overshoot is also within the appropriate range. In this case, the delivery worker can use this delivery container 3 for delivery work. Therefore, the terminal device 1 can notify the delivery worker that the temperature inside the delivery container 3 is within the appropriate range when the temperature inside the delivery container 3 reaches the minimum temperature reached and then becomes a stable temperature within the appropriate range.

Figure 7 (d) shows a case in which, in the first temperature change pattern, the minimum attainable temperature inside the delivery container 3 drops to a temperature lower than the lower limit, but the stable temperature after the overshoot is within the appropriate range. Even in this case, the delivery worker can use this delivery container 3 for delivery work. Therefore, the terminal device 1 can notify the delivery worker that the temperature inside the delivery container 3 is within the appropriate range when the temperature inside the delivery container 3 rises after reaching the minimum attainable temperature and then becomes a stable temperature within the appropriate range.

7(e) shows a case in which the minimum temperature inside the delivery container 3 drops below the lower limit in the first temperature change pattern, and the stable temperature after the overshoot is lower than the lower limit. In this case, the delivery worker cannot use this delivery container 3 for delivery work. Therefore, when the terminal device 1 determines that the temperature inside the delivery container 3 is outside the appropriate temperature range even if the temperature rises and reaches a stable temperature after reaching the minimum temperature, it can notify the delivery worker that the temperature inside the delivery container 3 is outside the appropriate temperature range. In this case, the terminal device 1 may notify the delivery worker that, for example, there may be too many ice packs put into the delivery container 3, that the type of ice packs is inappropriate, or that the arrangement of the ice packs in the delivery container 3 is inappropriate.

7(f) shows a case where the minimum temperature inside the delivery container 3 falls to a temperature lower than the lower limit and the stable temperature after the overshoot is higher than the upper limit in the first temperature change pattern. In this case, the temperature inside the delivery container 3 is within the appropriate temperature range for a short time after the overshoot, but is outside the appropriate temperature range thereafter, so the delivery worker cannot use this delivery container 3 for delivery work. Therefore, the terminal device 1 can notify the delivery worker that the temperature inside the delivery container 3 is outside the appropriate temperature range when the temperature inside the delivery container 3 increases and becomes higher than the upper limit after the temperature inside the delivery container 3 reaches the minimum temperature, or when the temperature inside the delivery container 3 becomes a stable temperature higher than the upper limit. In this case, the terminal device 1 may also notify the delivery worker that, for example, the number of ice packs put into the delivery container 3 may be insufficient, the type of ice packs may be inappropriate, or the ice packs may not be sufficiently cooled.

Figure 8 (g) shows a case where the minimum temperature reached inside the delivery container 3 is higher than the upper limit in the second temperature change pattern. In this case, the temperature inside the delivery container 3 does not fall within the appropriate temperature range. Therefore, when the terminal device 1 predicts that the minimum temperature reached is higher than the appropriate temperature range in the second temperature change pattern, it can notify the delivery worker that the temperature inside the delivery container 3 may not fall within the appropriate temperature range. In this case, the terminal device 1 may notify the delivery worker that, for example, there may not be enough ice packs put into the delivery container 3, that the type of ice packs is inappropriate, or that the ice packs may not be sufficiently cooled.

Figure 8 (h) shows a case where the minimum temperature reached inside the delivery container 3 is within the appropriate range in the second temperature change pattern. In this case, the delivery worker can use this delivery container 3 for delivery work. Since the minimum temperature reached and the subsequent stable temperature are almost the same in the second temperature change pattern, the terminal device 1 can notify the delivery worker that the temperature inside the delivery container 3 is within the appropriate range when the temperature inside the delivery container 3 reaches the minimum temperature reached, or when the predicted value of the minimum temperature reached is within the appropriate temperature range and the temperature inside the delivery container 3 enters the appropriate temperature range.

8(i) shows a case where the minimum temperature reached inside the delivery container 3 is lower than the lower limit in the second temperature change pattern. In this case, the temperature inside the delivery container 3 will not fall within the appropriate temperature range until the inserted ice pack melts, and the delivery worker cannot use this delivery container 3 for delivery work. Therefore, when the terminal device 1 predicts that the minimum temperature reached is lower than the appropriate temperature range in the second temperature change pattern, or when the temperature inside the delivery container 3 falls below the lower limit, it can notify the delivery worker that the temperature inside the delivery container 3 is outside the appropriate temperature range. In this case, the terminal device 1 may notify the delivery worker that, for example, there may be too many ice packs put into the delivery container 3, that the type of ice packs is inappropriate, or that the arrangement of the ice packs in the delivery container 3 is inappropriate.

In this way, in the information processing system according to this embodiment, different temperature conditions are defined for each temperature change pattern, and the terminal device 1 determines which temperature change pattern it is based on the delivery worker's input or its own judgment, and uses the temperature conditions according to the temperature change pattern to determine whether the temperature inside the delivery container 3 has reached the appropriate temperature range, etc.

9 and 10 are flowcharts showing the procedure of the temperature determination process performed by the terminal device 1 according to this embodiment. The processing unit 11 of the terminal device 1 according to this embodiment starts the process of this flowchart, for example, by the operation of a delivery worker who puts ice packs into the delivery container 3. The reaching temperature prediction unit 11b of the processing unit 11 performs a process of predicting the minimum reaching temperature of the temperature inside the delivery container 3 based on the time-series temperature information repeatedly acquired periodically from the delivery container 3 by the information acquisition unit 11a (step S1). At this time, the reaching temperature prediction unit 11b calculates the rate of change (first derivative value) of the temperature inside the delivery container 3 and the rate of change (second derivative value) of this rate of change based on the temperature information for several times from the start of the process, for example, and calculates the temperature inside the delivery container 3 when the rate of change of the temperature becomes 0, and the calculated temperature can be used as the predicted value of the minimum reaching temperature.

The processing unit 11 then determines whether or not a temperature change pattern has been input by the delivery worker, for example, before the start of processing (step S2). If a temperature change pattern has been input (S2: YES), the processing unit 11 proceeds to step S4. If a temperature change pattern has not been input (S2: NO), the pattern determination unit 11c of the processing unit 11 performs a temperature change pattern determination process to determine whether the temperature change pattern is the first temperature change pattern or the second temperature change pattern based on the temperature information acquired by the information acquisition unit 11a (step S3), and proceeds to step S4. Details of the temperature change pattern determination process will be described later.

The temperature determination unit 11d of the processing unit 11 determines whether the temperature change pattern input by the delivery worker or the temperature change pattern determined in the processing of step S3 is the first temperature change pattern (step S4). If it is the first temperature change pattern (S4: YES), the temperature determination unit 11d determines whether the minimum temperature predicted in step S1 is higher than the upper limit of the appropriate temperature range (step S5). If the minimum temperature is higher than the upper limit (S5: YES), the notification processing unit 11e of the processing unit 11 notifies the error by displaying a message such as "Please check the ice pack. There may be insufficient freezing, insufficient quantity, or an incorrect selection of ice pack type" on the display unit 14 (step S9), and ends the processing.

If the lowest temperature is lower than the upper limit (S5: NO), the temperature determination unit 11d determines whether the temperature inside the delivery container 3 has reached a stable temperature (step S6). At this time, the temperature determination unit 11d repeatedly calculates the rate of change of the temperature inside the delivery container 3 based on the temperature information periodically acquired by the information acquisition unit 11a after the temperature inside the delivery container 3 has reached the lowest temperature. The temperature determination unit 11d can determine that the temperature inside the delivery container 3 has reached a stable temperature when the repeatedly calculated rate of change is in a state where the rate of change is ≒ 0 (a state where the rate of change is within the range of 0 ± α) for a predetermined number of consecutive times. The value of α and the number of consecutive times for determining that the stable temperature has been reached are determined in advance by the designer of the information processing system according to this embodiment. If the temperature inside the delivery container 3 has not reached the stable temperature (S6: NO), the temperature determination unit 11d waits until the stable temperature is reached.

If the temperature inside the delivery container 3 reaches a stable temperature (S6: YES), the temperature determination unit 11d determines whether the stable temperature is higher than the lower limit and lower than the upper limit of the appropriate temperature range (step S7). If the stable temperature is higher than the lower limit and lower than the upper limit of the appropriate temperature range (S7: YES), i.e., if the stable temperature is within the appropriate temperature range, the notification processing unit 11e displays a message such as "The appropriate temperature has been reached" on the display unit 14 to notify that the temperature inside the delivery container 3 is within the appropriate temperature range (step S8), and ends the process.

If the stable temperature is lower than the lower limit or higher than the upper limit of the appropriate temperature range (S7: NO), i.e., if the stable temperature is outside the appropriate temperature range, the notification processing unit 11e displays a message on the display unit 14 to notify of the error (step S9), and ends the process. If the stable temperature is lower than the lower limit, the notification processing unit 11e can display a message such as "Please check the ice pack. There may be an excess quantity, an incorrect selection of the ice pack type, or an incorrect installation position of the ice pack." If the stable temperature is higher than the upper limit, the notification processing unit 11e can display a message such as "Please check the ice pack. There may be insufficient freezing, insufficient quantity, or an incorrect selection of the ice pack type."

Also, if the temperature change pattern is not the first temperature change pattern, i.e., the second temperature change pattern (S4: NO), the temperature determination unit 11d determines whether the lowest temperature predicted in step S1 is higher than the lower limit and lower than the upper limit of the appropriate temperature range (step S10). If the lowest temperature is lower than the lower limit or higher than the upper limit of the appropriate temperature range (S10: NO), the notification processing unit 11e displays a message on the display unit 14 to notify of an error (step S13), and ends the process. At this time, if the lowest temperature is lower than the lower limit, the notification processing unit 11e can display a message such as "Please check the cooling material. There may be an excessive amount, an incorrect selection of the cooling material type, or an incorrect installation position of the cooling material." If the lowest temperature is higher than the upper limit, the notification processing unit 11e can display a message such as "Please check the cooling material. There may be insufficient freezing, insufficient quantity, or an incorrect selection of the cooling material type."

If the lowest temperature reached is higher than the lower limit and lower than the upper limit of the appropriate temperature range (S10: YES), i.e., if the lowest temperature reached is within the appropriate temperature range, the temperature determination unit 11d determines whether the current temperature inside the delivery container 3 is lower than the upper limit of the positive temperature range based on the latest temperature information acquired by the information acquisition unit 11a (step S11). If the current temperature is higher than the upper limit (S11: NO), the temperature determination unit 11d waits until the current temperature falls below the upper limit. If the current temperature is lower than the upper limit (S11: YES), the notification processing unit 11e displays a message such as "The temperature has reached the appropriate range" on the display unit 14 to notify that the temperature inside the delivery container 3 is within the appropriate temperature range (step S12), and ends the process.

Figure 11 is a flowchart showing the procedure of the temperature change pattern determination process performed by the terminal device 1 according to this embodiment, which is the process performed in step S3 of the flowchart shown in Figure 9. The information acquisition unit 11a of the processing unit 11 of the terminal device 1 according to this embodiment acquires temperature information from the delivery container 3 (step S21). The pattern determination unit 11c of the processing unit 11 calculates the rate of change of the temperature inside the delivery container 3 based on the temperature information acquired by the information acquisition unit 11a (step S22). The pattern determination unit 11c determines whether the rate of change calculated in step S22 is in a state where the rate of change is ≒ 0 (a state where the rate of change is within the range of 0 ± α) (step S23).

If the rate of change is ≈ 0 (S23: YES), the pattern determination unit 11c determines whether the rate of change ≈ 0 state has continued a predetermined number of times based on the temperature information repeatedly acquired by the information acquisition unit 11a (step S24). If the rate of change ≈ 0 state has not continued a predetermined number of times (S24: NO), the pattern determination unit 11c returns the process to step S21. If the rate of change ≈ 0 state has continued a predetermined number of times (S24: YES), the pattern determination unit 11c determines that the temperature change pattern is the second temperature change pattern (step S26) and ends the temperature change pattern determination process.

If the rate of change is not ≈ 0 (S23: NO), the pattern determination unit 11c compares the rate of change calculated last time with the rate of change calculated this time to determine whether the sign of the rate of change has inverted from negative to positive (step S25). If the sign of the rate of change has not inverted (S25: NO), the pattern determination unit 11c returns the process to step S21. If the sign of the rate of change has inverted from negative to positive (S25: YES), the pattern determination unit 11c determines that the temperature change pattern is the first temperature change pattern (step S27) and ends the temperature change pattern determination process.

<Summary>
In the information processing system according to the present embodiment having the above configuration, the terminal device 1 acquires the internal temperature measured by the temperature sensor 34 provided in the delivery container 3, determines whether the acquired internal temperature of the delivery container 3 satisfies the temperature condition associated with a temperature change pattern, and notifies the determination result. The temperature change pattern can be, for example, either a first temperature change pattern including an overshoot in the temperature change, or a second temperature change pattern including no overshoot. As a result, the information processing system is expected to realize support for temperature management suited to the temperature change pattern of the delivery container 3.

In addition, in the information processing system according to this embodiment, the terminal device 1 accepts input of a temperature change pattern from the delivery worker and determines whether the temperature conditions associated with the accepted temperature change pattern are met. As a result, when the temperature change pattern can be determined in light of the delivery worker's experience, etc., the information processing system is expected to be able to accept an appropriate temperature change pattern from the delivery worker and provide support for temperature management.

Furthermore, in the information processing system according to this embodiment, the terminal device 1 determines the temperature change pattern of the delivery container 3 based on the temperatures at multiple points in time periodically acquired from the delivery container 3. The terminal device 1 can calculate the temperature change rate based on the temperatures at multiple points in time acquired from the delivery container 3, and determine the temperature change pattern based on the calculated temperature change rate. As a result, even if the delivery worker is unable to determine the temperature change pattern, the information processing system is expected to enable the terminal device 1 to determine the temperature change pattern and provide support for temperature management based on the appropriate temperature change pattern.

In addition, in the information processing system according to this embodiment, the terminal device 1 calculates the temperature change rate based on the temperatures periodically acquired from the delivery container 3 at multiple points in time, calculates the temperature to be reached when the direction of the temperature change is reversed based on the calculated temperature change rate, and determines whether the calculated temperature to be reached is within a predetermined temperature range. This allows the information processing system to predict the temperature to be reached inside the delivery container 3 based on the temperature change rate, and is expected to make a determination at an earlier timing based on the predicted temperature to be reached.

In addition, in the information processing system according to this embodiment, when the temperature change pattern is the first temperature change pattern including an overshoot, the terminal device 1 acquires the stable temperature when the temperature inside the delivery container 3 stabilizes after the direction of the temperature change for this overshoot is reversed, and determines whether the stable temperature is within a predetermined temperature range. This allows the information processing system to be expected to accurately determine that the delivery container 3 has entered the appropriate temperature range without making an erroneous determination due to a temperature change during an overshoot.

In this embodiment, the case where cold insulation is performed by putting a cold insulation material into the delivery container 3 has been described, but the technology according to this embodiment is not limited to cold insulation and can be applied to heat insulation as well. When pre-warmed insulation material is put into the delivery container 3, the temperature inside the delivery container 3 rises and reaches a stable temperature, but there are two types of temperature change patterns: one where the stable temperature is reached after an overshoot, and the other where the stable temperature is reached without an overshoot. The information processing system performs the above-mentioned cold insulation process by inverting the positive and negative signs, for example, by changing the upper limit value to the lower limit value, the lower limit value to the upper limit value, the minimum temperature to the maximum temperature, the minimum temperature to the maximum temperature, an increase to a decrease, and a decrease to an increase, and by reversing the direction of the inequality sign in the conditions, so that it can handle cases where heat insulation is performed.

The terminal device 201 receives information transmitted from the server device 202, and notifies the delivery worker of the prediction results and determination results of the temperature inside the delivery container 3 based on the received information.

Figure 13 is a block diagram showing an example of the configuration of the server device 202 according to the second embodiment. The server device 202 according to the second embodiment is configured to include a processing unit 221, a storage unit 222, and a communication unit 223. The processing unit 221 is configured using an arithmetic processing device such as a CPU or an MPU, a ROM, a RAM, etc. The processing unit 221 reads and executes a program 222a stored in the storage unit 222 to perform processes such as prediction and determination of the internal temperature of the delivery container 3.

The storage unit 222 is configured using a large-capacity storage device such as a hard disk. In the second embodiment, the storage unit 222 stores a program 222a executed by the processing unit 221. The program 222a may be provided in the form of distribution via a network, or may be provided in the form of being recorded on a recording medium 98. The communication unit 223 communicates with one or more terminal devices 201 used by delivery workers via a network including, for example, the Internet, a LAN (Local Area Network), or a mobile phone communication network.

The storage unit 222 may be an external storage device connected to the server device 202. The server device 202 may be a multi-computer including multiple computers, or may be a virtual machine virtually constructed by software. The server device 202 is not limited to the above configuration, and may include, for example, a reading unit that reads information stored in a portable storage medium, an input unit that accepts operation input, or a display unit that displays images.

In addition, in the server device 202 according to the second embodiment, the processing unit 221 reads out and executes the program 222a stored in the memory unit 222, whereby the information acquisition unit 211a, the attained temperature prediction unit 11b, the pattern determination unit 11c, the temperature determination unit 11d, the notification processing unit 211e, and the like are realized in the processing unit 221 as software-based functional units.

The processes performed by the temperature prediction unit 11b, the pattern determination unit 11c, and the temperature determination unit 11d of the server device 202 according to the second embodiment are substantially the same as the processes performed by the temperature prediction unit 11b, the pattern determination unit 11c, and the temperature determination unit 11d of the terminal device 1 according to the first embodiment, and therefore will not be described.

The notification processing unit 221e performs processing to notify the terminal device 201 of the judgment result by transmitting information including the judgment result by the temperature judgment unit 11d to the terminal device 201. For example, when the temperature inside the delivery container 3 falls within the appropriate temperature range, the notification processing unit 221e causes the terminal device 201 to notify that preparation is complete. For example, when the temperature inside the delivery container 3 falls outside the appropriate temperature range, the notification processing unit 221e causes the terminal device 201 to notify that an abnormality has occurred.

Although a block diagram is omitted, the terminal device 201 according to the second embodiment does not need to have the reached temperature prediction unit 11b, the pattern determination unit 11c, and the temperature determination unit 11d of the terminal device 1 according to the first embodiment shown in FIG. 2.
