[data structure]
Next, the data structure of the child device management table 36 and each database will be described with reference to FIGS. 7 and 8.

FIG. 7A is an example of the data structure of the child device management table 36. The child device management table 36 illustrated in FIG. 7A has an item of “child device ID” and an item of “state”. In the “slave unit ID” item, a slave unit ID included in the slave unit information Sb received by the master unit 3 is registered. The item “state” indicates that the master device 3 has already received the measurement information Sc including the corresponding slave device ID, and the master device 3 has been able to confirm the presence of the target slave device 7 “confirmed”. , Or “unconfirmed” indicating that the master unit 3 has not received the measurement information Sc including the corresponding slave unit ID and the presence of the target slave unit 7 cannot be confirmed. Is recorded. For example, when there is a child device ID whose item “state” has been “unconfirmed” for a predetermined time or longer, the parent device 3 warns that the child device 7 corresponding to the child device ID does not exist in the loading platform 10. Etc. are output.

FIG. 7B is an example of the data structure of the delivery schedule DB 96. The delivery schedule DB 96 shown in FIG. 7B has items of "Package ID", "Truck ID", "Box ID", "Child Machine ID", "Scheduled Delivery Date", and "Delivery Location".

In the "Luggage ID" item, a luggage ID, which is identification information of the luggage to be transported, is recorded. In the "Truck ID" item, the truck ID of the vehicle that transports the luggage having the corresponding luggage ID is recorded. In the “box ID” item, a box ID, which is identification information of the heat insulating box 5 in which the package having the corresponding package ID is stored, is recorded. In the item “slave unit ID”, the slave unit ID of the slave unit 7 installed in the heat insulating box 5 indicated by the corresponding box ID is recorded. The scheduled delivery date and time is recorded with the scheduled delivery date and time when the delivery of the package with the corresponding package ID is completed. In the item “delivery location”, the delivery address of the package having the corresponding package ID is recorded. The delivery schedule DB 96 may be subdivided into a plurality of databases. For example, the delivery schedule DB 96 may be composed of a database in which package IDs, truck IDs, box IDs, and slave device IDs are associated with each other, a package ID, a scheduled delivery date and time, and a delivery location. Good. The delivery schedule DB 96 is an example of the “delivery information” in the present invention.

FIG. 8A is an example of the data structure of the temperature management DB 97. The temperature management DB 97 shown in FIG. 8A has an item of “box ID” and an item of “allowable temperature zone”. In the “box ID” item, the box ID of each heat-insulating box 5 in which the cargo to be transported is stored is recorded. In the "allowable temperature zone" item, the allowable temperature zone of the package accommodated in the heat insulating box 5 indicated by the corresponding box ID is recorded.

Here, a specific example of the abnormality determination of the internal temperature of the heat insulating box 5 with reference to the temperature management DB 97 will be supplementarily described. For example, when the server device 9 receives the measurement information Sc from the terminal device 2, the server device 9 refers to the delivery schedule DB 96 or the like shown in FIG. 7B for the box ID corresponding to the child device ID included in the measurement information Sc. The specified temperature range corresponding to the specified box ID is extracted from the temperature management DB 97 shown in FIG. Then, the server device 9 compares the allowable temperature range extracted from the temperature management DB 97 with the temperature indicated by the temperature information included in the target measurement information Sc, and thereby the internal temperature of the heat insulating box 5 indicated by the specified box ID. The presence or absence of abnormality is judged.

FIG. 8B is an example of the data structure of the temperature accumulation DB 98. The temperature accumulation DB 98 shown in FIG. 8B has items of “box ID”, “temperature”, “date and time”, and “position”. The server device 9 creates a record in the temperature accumulation DB 98 for each measurement information Sc.

In the “box ID” item, a box ID corresponding to the slave ID included in the measurement information Sc received from the terminal device 2 is recorded. In the “temperature” item, the temperature indicated by the temperature information included in the target measurement information Sc is recorded. In the item “date and time”, the date and time indicated by the date and time information included in the target measurement information Sc is recorded. In the “position” item, the latitude and longitude based on the position information of the delivery vehicle 1 transmitted from the terminal device 2 is recorded together with the target measurement information Sc.

[Processing flow]
FIG. 9 is a flowchart showing a processing procedure of the temperature management system 100 in this embodiment.

The terminal device 2 transmits the vehicle information Sa including the truck ID of the delivery vehicle 1 to the server device 9 at a predetermined timing (step S101). For example, when the terminal device 2 detects a predetermined user input by the input unit 22, the terminal device 2 determines that the temperature management of the load in the cargo bed 10 should be started, and the vehicle information including the track ID stored in the storage unit 23 in advance. The Sa is transmitted to the server device 9.

When the server device 9 receives the vehicle information Sa from the terminal device 2, the server device 9 refers to the delivery schedule DB 96 and searches for all the child device IDs associated with the truck ID included in the vehicle information Sa (step S102). .. As a result, the server device 9 identifies the child device ID of the child device 7 installed in the heat insulation box 5 loaded on the delivery vehicle 1.

Then, the server device 9 transmits the child device information Sb including the child device ID searched in step S102 to the terminal device 2 (step S103). When the terminal device 2 receives the child device information Sb from the server device 9, the terminal device 2 transfers the child device information Sb to the parent device 3 (step S104).

The parent machine 3 that has received the child machine information Sb registers the child machine ID included in the child machine information Sb in the child machine management table 36 (step S105). The item of “state” corresponding to the child device ID registered in the child device management table 36 illustrated in FIG. 7A is initially set to “unconfirmed”.

After that, when the measurement information Sc is received from the slave 7, the master 3 determines whether the measurement information Sc is transmitted from the slave 7 registered in the slave management table 36 (step S106). Specifically, the parent device 3 determines whether the child device ID included in the received measurement information Sc is registered in the child device management table 36. Then, when the parent device 3 determines that the measurement information Sc is received from the child device 7 registered in the child device management table 36 (step S106; Yes), the received measurement information Sc is transmitted to the terminal device 2 ( Step S107). Further, the parent device 3 sets the item “state” of the child device management table 36 corresponding to the child device ID of the child device 7 that is the transmission source of the measurement information Sc to “confirmed”.

On the other hand, when the parent device 3 determines that the measurement information Sc has been received from the unregistered child device 7 in the child device management table 36 (step S106; No), the parent device 3 does not send the measurement information Sc to the terminal device 2. Discard. As a result, even when the parent device 3 receives the measurement information Sc from the child device 7 that measures the internal temperature of the heat insulating box 5 loaded on another delivery vehicle, the server device does not need the measurement information Sc. It is possible to prevent sending to 9.

After the master device 3 transmits the measurement information Sc to the terminal device 2 in step S107, the terminal device 2 transfers the measurement information Sc received from the master device 3 to the server device 9 (step S109). In this case, the terminal device 2 adds the position information of the delivery vehicle 1 output by the GPS receiver 26 to the measurement information Sc and transmits the measurement information Sc. In addition, the terminal device 2 may immediately transmit the measurement information Sc received from the parent device 3 to the server device 9, temporarily accumulate the measurement information Sc to be transmitted, and at a predetermined time interval or a predetermined timing. It may be transmitted to the server device 9.

When the server device 9 receives the measurement information Sc from the terminal device 2, the server device 9 updates the temperature accumulation DB 98 based on the measurement information Sc and also refers to the temperature management DB 97, and there is no heat insulation box 5 that is out of the allowable temperature range. Whether or not the temperature is abnormal is determined (step S110). Then, when the server device 9 determines that there is the heat insulating box 5 that is out of the allowable temperature range defined in the temperature management DB 97, the server device 9 stores the determination result, or the temperature adjusting material 8 is added to the heat insulating box 5 having the temperature abnormality. The terminal device 2 is caused to output a warning by transmitting warning information to the effect that it should be input to the terminal device 2. In addition, when there is a terminal used by the administrator who manages the state of each delivery vehicle 1 separately from the server device 9, the server device 9 sends a mail to the above-mentioned terminal when it determines that a warning is necessary. May be further performed.

In step S108, the parent device 3 determines whether or not the delivery of the luggage loaded on the loading platform 10 is completed (step S108). Generally, when the delivery box 1 arrives at the delivery place and the heat-insulating box 5 is taken out of the loading platform 10 together with the luggage and leaves the delivery vehicle 1, the main unit 3 sends the measurement information Sc transmitted from the child device 7 housed in the heat-insulating box 5. You will not be able to receive it. Therefore, for example, the parent device 3 monitors whether or not the measurement information Sc is received from each of the child devices 7 registered in the child device management table 36, and receives the measurement information Sc from all of these child devices 7. If it is no longer possible, we will judge that the delivery is completed. In another example, the parent device 3 determines that the delivery is completed when the user input indicating the end of the transmission process of the measurement information Sc or the predetermined instruction signal from the terminal device 2 is detected. Good. Then, when the parent device 3 determines that the delivery is completed (step S108; Yes), the process of the flowchart ends. On the other hand, when the parent device 3 determines that the delivery is not completed (step S108; No), the process is returned to step S106, and the process of transferring the measurement information Sc to the terminal device 2 is continuously performed.

Preferably, in the case where the parent machine 3 has a child machine ID whose item “state” is “unconfirmed” even after a predetermined time elapses after the registration processing of the child machine management table 36 in step S105. It is preferable to output a warning that the child device 7 having the child device ID does not exist. In this case, the parent device 3 may transmit warning instruction information including the child device ID or the like whose item “state” is “unconfirmed” to the terminal device 2 and cause the terminal device 2 to output the warning. As a result, it is possible to reliably prevent forgetting to load the heat insulation box 5 on the delivery vehicle 1 or forgetting to attach the slave unit 7 to the heat insulation box 5.

[Operation and effect of this embodiment]
According to the present embodiment, the server device 9 stores the delivery schedule DB 96 in which the child machine ID, the truck ID, and the like are associated in advance according to the delivery schedule of the package, and the child machine associated with the truck ID indicated by the vehicle information Sa. The ID is transmitted to the parent device 3 via the terminal device 2. As a result, the parent device 3 can suitably generate the child device management table 36, and it is not necessary to manually register the child device 7 loaded on the loading platform 10 in the parent device 3. Therefore, it is possible to preferably realize the reduction of the time required for loading the luggage onto the delivery vehicle 1, the prevention of erroneous operation of the registration operation of the child device 7 to the parent device 3, and the reduction of the work amount of the worker.

Further, in general, when approaching another delivery vehicle loaded with the heat insulation box 5, the parent device 3 sends the measurement information Sc from the child device 7 that measures the internal temperature of the heat insulation box 5 loaded on the other delivery vehicle. Receiving occurs. Even in this case, the parent machine 3 refers to the child machine management table 36 to refer to the child machine information Sb indicating the internal temperature of the heat insulating box 5 loaded on the delivery vehicle 1 in which the parent machine 3 is mounted. It is possible to preferably send only to the server device 9.

[Modification]
Below, the modification of the above-mentioned embodiment is explained. Note that the following modified examples can be applied to the embodiment in any combination.

(Modification 1)
The temperature management system 100 shown in FIG. 1 is an example, and the configuration to which the present invention is applicable is not limited to this.

FIG. 10 shows a configuration of a temperature management system 100A according to the modified example. In the temperature management system 100A shown in FIG. 10, the master unit 3A includes the function of the terminal device 2 of the temperature management system 100 shown in FIG. 1, and communicates with the server device 9 without going through the terminal device 2.

In this case, the parent device 3A stores the truck ID of the delivery vehicle 1 in advance, and transmits the vehicle information Sa to the server device 9 at a predetermined timing after loading the heat-insulating box 5 onto the loading platform 10, thereby making the server device 9 The child device information Sb is received from the device 9. Then, as in the above-described embodiment, the parent device 3A generates the child device management table 36 from the received child device information Sb, refers to the child device management table 36, and measures the measurement information Sc received from the child device 7. Is transferred to the server device 9 or not.

Even in this mode, the parent device 3A can suitably transmit only the measurement information Sc received from the child device 7 housed in the heat insulating box 5 to be loaded on the loading platform 10 to the server device 9.

The server device 9 may be composed of a plurality of terminals connected via a network. In this case, each terminal exchanges information necessary for executing the pre-allocated process with another terminal. For example, the server device 9 may include a terminal that stores the delivery schedule DB 96, the temperature management DB 97, and the temperature accumulation DB 98, and a terminal that executes the process of the control unit 95 according to the embodiment. In another example, the server device 9 receives the vehicle information Sa from the terminal device 2 and transmits the child device information Sb, and the measurement information Sc from the terminal device 2 to update the temperature accumulation DB 98 and manage the temperature. It may be configured with a terminal that makes an abnormal temperature determination based on DB97.

(Modification 2)
In the flowchart of FIG. 9, the master device 3 refers to the slave device management table 36 every time the measurement information Sc is received, and determines whether or not the measurement information Sc should be transmitted to the terminal device 2. Alternatively, when the base unit 3 performs connection-type communication with the handset unit 7, the base unit 3 establishes a connection with the handset unit 7 registered in the handset unit management table 36, and from the handset unit 7 that has established the connection. The measurement information Sc may be received and transferred to the terminal device 2. In this case, the child device 7 transmits a communication establishment request including the child device ID to the parent device 3, and the parent device 3 determines that the child device ID included in the communication establishment request is registered in the child device management table 36. Only, the connection with the slave unit 7 is established. According to this aspect, the parent device 3 does not need to perform the authentication process of the child device 7 that is the transmission source of the measurement information Sc each time the measurement information Sc is received.
