Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process for storing goods in a container, and loading the goods in a truck or other vehicle as a load and handling the goods.

A remote base station or a logistics management center that can centrally monitor vehicle information on generators such as current and the internal environmental temperature of a fixed base that temporarily stores containers. It concerns monitoring methods.

[0002]

2. Description of the Related Art In recent years, in logistics for delivering goods,
There is an increasing demand for maintaining and controlling the temperature during transportation of fresh foods, drugs, chemicals, blood, and the like within a predetermined range.

Conventionally, as a means for meeting the demand, articles having the same transport conditions are collectively stored in the same container, mounted on a vehicle and transported, and the container being transported is mounted on the mounted vehicle. At present, the temperature state inside the container is displayed and recorded on the terminal device in relation to the terminal device, and the crew monitors the temperature condition as appropriate to determine whether there is an abnormality.

In the above-mentioned monitoring, the container to be monitored is inevitably the unit of a vehicle on which the container is mounted, and thus lacks a function of centrally monitoring a large number of transport vehicles. Therefore, the monitoring efficiency when a large number of similar transport vehicles are deployed simultaneously is extremely poor.

[0005] When an abnormality in the state of the inside of these containers is found during transportation, there is usually no step other than taking steps after arriving at the nearest base station. Therefore, even if the abnormal condition is detected early during transportation, it is often the case that an unexpected loss is incurred due to delay in the preparation of the measures and the measures for dealing with the abnormal conditions.

[0006]

SUMMARY OF THE INVENTION The main constitution of the present invention is to solve the drawbacks caused by the fact that the containers to be monitored are inevitably limited to the units of vehicles equipped with them, as in the prior art described above. Centralized monitoring of the internal environmental temperature of a large number of transport vehicles and containers related to generators and the internal temperature of fixed bases where containers are temporarily stored can be centrally monitored remotely, thus providing high monitoring efficiency and consistent information management It is an object of the present invention to provide a remote monitoring method of predetermined information on a cargo and a vehicle which can be monitored.

[0007]
