- a storage unit in which a relationship information table, a root information table and a sensor information table are stored,the relationship information table being configured to hold relationship information on one of packing and loading relationship and an installation relationship between a transport object, a transportation unit capable of packing, loading or transporting the transport object, and a sensor installed on one of the transport object and the transportation unit, the relationship information including information on a hierarchy of identifiers associated with respective objects establishing the relationship,the root information table being configured to hold root information on each upper layer and lower layer identifier pair establishing one of the packing and loading relationship and the installation relationship, an identifier at the highest layer in one of the packing and loading relationship and the installation relationship being taken as the upper layer identifier and set as the root information, andthe sensor information table being configured to hold an identifier of the sensor and a history of sensor information measured by the sensor associated with the identifier;
a relationship information registration part configured to receive, upon occurrence of a change in one of the packing and loading relationship and the installation relationship, the relationship information on one of the packing and loading relationship and the installation relationship in which the change has occurred, from one of an input unit and an external terminal via a communication unit, register the relationship information into the relationship information table, perform a search on the root information table using a key the lower layer identifier in the pair of identifiers indicated by the received relationship information a key, specify a dependant identifier having the lower layer identifier as an upper layer identifier thereof, specify corresponding root information by performing a search on the root information table using the upper layer identifier in the pair of identifiers as a key, and register the specified root information into the root information table as root information of the dependent identifier; and
a sensor information searching part configured to receive a reference request for sensor information corresponding to one of a certain transport object and a certain transportation unit, the reference request being received from one of the input unit and the external terminal via the communication unit, obtain an identifier located at the highest layer among identifiers related with the transport object or the transportation unit, the identifier being obtained from the root information table, obtain the sensor information from the sensor information table with the obtained identifier being a key, and output the sensor information as the sensor information on one of the transport object and the transportation unit to one of an output unit or the external terminal via the communication unit.

Abstract
An object of the present invention is to manage various containment relationships such as packing relationships and loading relationships of an article, to efficiently search for sensor information measured by a sensor associated with the article, and thereby to provide the sensor information to the user. A system 100 includes a relationship information registration part 1001 and a sensor information searching part 1002. The relationship information registration part 1001: registers relationship information in a relationship information table; searches a root information table by using as a key a lower layer identifier in paired identifiers shown by the relationship information to find a dependent identifier having the lower layer identifier as an upper layer identifier thereof; searches the root information table by using as a key an upper layer identifier in the paired identifiers to find corresponding root information; and registers the found root information as root information of the dependent identifier in the root information table. The sensor information searching part 1002: receives, from an external terminal or the like, a reference request for sensor information of a transport objector transportation unit; obtains, from the root information table, an identifier located at the highest position in all the relationships with the transport object or transportation unit; obtains, from the sensor information table, sensor information by using the obtained identifier as a key; and outputs, to the external terminal or the like, the sensor information as sensor information of the transport object or transportation unit.
