20240095653
The present invention relates to a delivery management system, a delivery management method, and a program.
Conventionally, in a process of accommodating articles such as pharmaceutical products or foods and delivering the articles, a sensor information management system in which an environment status such as the temperature and the humidity in a container that accommodates therein the articles during delivery is measured automatically by a sensor, and an environment history represented by a measured value is transmitted together with the articles has been known.
As an example of such a conventional sensor information management system, Patent Literature 1 has been known.
In Patent Literature 1, in order to provide an environment history acquired from the environment during transport or storage of articles, such a technique has been disclosed that a wireless tag that transmits a unique tag number is added to an article, and a package that stores the article therein includes a first node connected to a sensor that measures a physical quantity of the environment and a second node that receives information transmitted from the first node, thereby enabling to transmit and receive the tag number and a measurement value transmitted from the first node.
More specifically, the first node includes a tag number reader that requests transmission of a tag number to the wireless tag and receives the tag number, a measurement value reader that reads a value measured by a sensor, and a transmission unit that transmits the tag number and the measurement value. The second node includes a reception unit that receives the tag number and the measurement value transmitted by the transmission unit, an information storage unit that stores therein information received by the reception unit, and a node-information transmission and reception unit that transmits and receives information stored in the information storage unit. The technique has an advantage such that quality control can be executed reliably by providing the environment history during transport or storage of the articles.
According to Patent Literature 1, there are such effects that articles are sorted during distribution, and even if the articles are reloaded, the history of the environment having passed through in each stage of a distribution route can be easily ascertained for an individual article, thereby enabling to control the quality reliably.
However, in Patent Literature 1, since the main object is to provide an environment history acquired from the environment during transport or storage of articles, quality control of the articles cannot be executed in real time.
For example, stock control of pharmaceutical products handled by medical institutions or the like requires, from the nature of the article, not only high expertness and knowledge with regard to handling thereof, but also storage in a special container and careful delivery according to the pharmaceutical product. Therefore, there has been a desire to execute quality control of articles in real time.
Therefore, it has been desired to develop a delivery management system that not only can provide an environment history acquired from the environment in a container during transport of articles, but also can manage the transport status of articles.
The present invention has been achieved in view of the above requirements, and an object of the present invention is to provide an environment history acquired from the environment of a container during transport of articles, ascertain the transport status including a transport route of the articles and the like, and execute quality control of the articles in real time.
In order to solve the above problems, the invention according to claim 1 is a delivery management system comprising a delivery unit for delivering a container in which an accommodated article is cooled by a refrigerant, and an article management server that communicates with the delivery unit during transport via a communication network, wherein the delivery unit includes a GPS receiver that receives each GPS signal from a plurality of GPS satellites to calculate location data based on each of the GPS signals, adds a unique device code to the location data, and transmits the location data to the article management server, a temperature measurement unit that measures a temperature in the container, a first memory unit that memorizes therein temperature data measured by the temperature measurement unit in a time series, and a first transmission unit that adds a unit number of the delivery unit to temperature data acquired from the first memory unit and transmits the temperature data regularly and/or irregularly to the article management server via the communication network, and the article management server includes a second memory unit that memorizes therein the location data and the device code received from the GPS receiver in association with each other, a third memory unit that memorizes therein the temperature data received from the delivery unit regularly and/or irregularly associated with each unit number, a fourth memory unit that memorizes therein the unit number and a serial number of the article in association with each other, and a transport-status-data generation unit that generates transport status data representing a serial number, location data, and temperature data of the article during transport based on location data acquired from the second memory unit corresponding to the device code, temperature data acquired from the third memory unit corresponding to the unit number, and serial number acquired from the fourth memory unit corresponding to the unit number, by using a set of a certain unit number and a device code as a key.
