1. A delivery management method executed by a delivery management system including 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 performs:
a GPS reception step of receiving each GPS signal from a plurality of GPS satellites to calculate location data based on each of the GPS signals, adding a unique device code to the location data, and transmitting the location data to the article management server,
a temperature measurement step of measuring a temperature in the container,
a first memory step of memorizing temperature data measured by the temperature measurement step in a time series, and
at least one of a liquid level detection step of measuring liquid level data pertaining to a liquid level of the refrigerant, a vibration measurement step of measuring vibration data pertaining to vibration applied from a road surface to the container, a humidity measurement step of measuring humidity data pertaining to humidity in the container, and an opening/closing number counting step of counting pieces of opening/closing number data of a lid provided in the container,
wherein the first memory step memorizes the temperature data by adding at least one of the liquid level data, the vibration data, the humidity data, and the opening/closing number data, and date and time data thereto,
and the delivery unit further performs a first transmission step of adding at least one of the liquid level data, the vibration data, the humidity data, the opening/closing number data and date and time data, and further the unit number of the delivery unit to the temperature data acquired at the first memory step and transmitting the temperature data regularly and/or irregularly to the article management server via the communication network,
wherein the article management server performs:
a second memory step of memorizing the location data and the device code received at the GPS reception step in association with each other,
a third memory step of memorizing the temperature data, at least one of the liquid level data, the vibration data, the humidity data, and the opening/closing number data, and date and time data received from the delivery unit regularly and/or irregularly associated with the unit number respectively,
a fourth memory step of memorizing the unit number and a serial number of the article in association with each other, and
a transport-status-data generation step of generating transport status data representing a serial number, location data, and temperature data of the article during transport, at least one of the liquid level data, the vibration data, the humidity data, and the opening/closing number data, and date and time data, based on location data acquired at the second memory step corresponding to the device code, temperature data, at least one of the liquid level data, the vibration data, the humidity data, and the opening/closing number data, and date and time data acquired at the third memory step corresponding to the unit number, and serial number acquired at the fourth memory step corresponding to the unit number, by using a set of a certain unit number and a device code as a key.
