Abstract

A history concerning circumstances surrounding each item during distribution is obtained from a reusable measuring apparatus attached to the item or measuring apparatuses placed in locations such as rooms. Information about items of products in a distribution channel are managed by associating position information indicating the locations at both ends of a place where circumstance information is measured with measuring apparatuses with the information indicating the measuring apparatuses. When items are moved during distribution, information contained in a tag attached to the items is read at the locations at both ends of the place and is managed. To obtain information about circumstances surrounding an item at a particular place in the distribution channel, values measured with the measuring apparatuses during a relevant period are obtained on the basis of the position information indicating the locations at both ends of the particular place and on the read dates and times.

Claims

1. A circumstance information management system that obtains and manages circumstance information in a particular location of items that are moving,

the circumstance information management system having:

a movement history having at least an item identifier identifying an item, a location identifier identifying a location through which the item moved or passed, and information indicating movement dates and times at which the item moved or passed,

a circumstance history having at least a measuring apparatus identifier identifying a measuring apparatus that measures circumstance information about an item, a measured value measured with the measuring apparatus, and information about the date and time of the measurement, and

a circumstance-movement association master having a doorway identifier identifying a doorway to a particular location at which the measuring apparatus is placed and a measuring apparatus identifier identifying the measuring apparatus placed at the location,

the circumstance information management system comprising;

in order to obtain circumstance information about a particular item in a particular location,

means for obtaining from the circumstance-movement association master a doorway identifier associated with a measuring apparatus that obtains the circumstance information;

means for obtaining movement dates and times at which the item moved or passed through a location that matches the doorway identifier from the movement history and determining the movement dates and times as information indicating the period during which the item stayed at the location where the measuring apparatus that obtains circumstance information is placed; and

means for obtaining from the circumstance history a measured value measured with the measuring apparatus during the period.

2. The circumstance information management system according to claim 1, further comprising:

means for holding permissible limits of a measured value for each item or each type of item measured with a measuring apparatus;

means for obtaining a doorway identifier associated with the measuring apparatus from the circumstance-movement association master if a measured value that is out of the permissible limits is obtained with a measuring apparatus in a particular location;

means for obtaining an item that stays in a location that matches the doorway identifier from the movement history; and

means for providing a warning if the item matches an item or a type of item associated with the permissible limits.

3. A circumstance information management system that obtains and manages circumstance information in a particular location of items that are moving,

the circumstance information management system having:

a movement history having at least an item identifier identifying the item, a location identifier identifying a location through which the item moved or passed, and information indicating movement dates and times at which the item moved or passed,

a circumstance history having at least a measuring apparatus identifier identifying a measuring apparatus that measures circumstance information about an item, a measured value measured with the measuring apparatus, and information about the date and time of the measurement, and

a circumstance-item association master having at least a measuring apparatus identifier identifying a measuring apparatus that measures circumstance information about an item, an item identifier of an item to which the measuring apparatus is attached, and a attachment period during which the measuring apparatus is attached to the item,

the circumstance information management system comprising;

in order to obtain circumstance information about a particular item in a particular location,

means for obtaining from the movement history a period during which the item for which the circumstance information is to be obtained stayed at a particular location through which the item moved or passed;

means for obtaining an measuring apparatus identifier of a measuring apparatus associated with the item from the circumstance-item association master; and

means for obtaining from the circumstance history a measured value measured with a measuring apparatus that matches the measuring identifier apparatus during the period.

4. The circumstance information management system according to claim 3, further comprising:

means for holding permissible limits of a measured value for each item or each type of item measured with a measuring apparatus;

means for obtaining an item identifier of an item associated with a particular measuring apparatus from the circumstance-item association master if a measured value that is out of the permissible limits is obtained with the particular measuring apparatus; and

means for providing a warning if the item matches an item or type of item that is associated with the permissible limits.

5. An information management method for a circumstance information management system that obtains and manages circumstance information in a particular location of items that are moving, the circumstance information management system having a movement history having at least an item identifier identifying an item, a location identifier identifying a location through which the item moved or passed, and information indicating movement dates and times at which the item moved or passed;

a circumstance history having at least a measuring apparatus identifier identifying a measuring apparatus that measures circumstance information about an item, a measured value measured with the measuring apparatus, and information about the date and time of the measurement; and

a circumstance-movement association master having a doorway identifier identifying a doorway to a particular location at which the measuring apparatus is placed and a measuring apparatus identifier identifying the measuring apparatus placed at the location;

the information management method, when obtaining circumstance information about a particular item in a particular location, comprising the steps of;

obtaining from the circumstance-movement association master a doorway identifier associated with a measuring apparatus that obtains the circumstance information;

obtaining movement dates and times at which the item moved or passed through a location that matches the doorway identifier and determining the movement dates and times as information indicating the period during which the item stayed at the location where the measuring apparatus that obtains circumstance information is placed; and

obtaining from the circumstance history a measured value measured with the measuring apparatus during the period.

6. The information management method according to claim 5, further comprising the steps of:

holding permissible limits of a measured value for each item or each type of item measured with a measuring apparatus;

if a measured value that is out of the permissible limits is obtained with a measuring apparatus in a particular location,

obtaining a doorway identifier associated with the measuring apparatus from the circumstance-movement association master;

obtaining an item that stays in a location that matches the doorway identifier from the movement history; and

providing a warning if the item matches an item or a type of item associated with the permissible limits.

7. An information management method for a circumstance information management system that obtains and manages circumstance information in a particular location of items that are moving, the circumstance information management system having:

a movement history having at least an item identifier identifying an item, a location identifier identifying a location through which the item moved or passed, and information indicating movement dates and times at which the item moved or passed,
