Description

  The present invention relates to an article management technique using an IC tag used for managing an article that requires temperature management in an article management system using an IC tag, particularly an article management system for article distribution.

  Among the article management systems in distribution, a system that handles temperature information is currently a digital tachograph with a temperature recording function added. This is a vehicle operation management system for a transport vehicle that transports goods. In addition to the operation status such as position and speed, temperature information in the transport cargo room can be recorded.

  The actual temperature adjustment is performed by controlling the air conditioner according to the temperature value measured by the thermometer or temperature sensor provided in the cargo compartment, and is not necessarily linked to the digital tachograph, but digital By checking whether the temperature in the cargo compartment recorded by the tachograph is within a certain range after transportation or during transportation, the manager can manage the temperature of the article. In this case, although the temperature inside the cargo compartment is measured accurately and the temperature of the article itself is not measured, the environment inside the cargo compartment and the article are almost in thermal equilibrium during transportation. The temperature of both can be regarded as almost unchanged.

  However, except in the case of direct delivery to the production area, in the distribution process, re-transmission, temporary storage, sorting, etc. occur naturally through the producers, transporters, wholesalers, delivery companies, and retailers. The temperature control using the digital tachograph is closed only to the transport process in the transport vehicle.

  In recent years, a number of goods management systems using IC tags have been proposed and realized as systems for managing goods (supply chain management) from upstream to downstream in distribution, of which temperature management is performed. Several systems that make this possible have been proposed. Among these, there are three types of systems that are broadly divided into the following ones for the purpose of performing management up to individual product units.

  One is a method in which data on the temperature measured by a sensor is separately written in a passive IC tag attached to the article, and the sensor is located outside the article. As an example of this, there is JP 2002-96913 A “freight collection and delivery management system, delivery vehicle, electronic tag”. Since this method is not necessarily specialized at the time of transportation like a digital tachograph, it can be extended to various distribution processes rather than temperature management using a digital tachograph. However, the temperature of the environment surrounding the article such as the cargo compartment is measured, not the temperature of the article. For this reason, there is a problem that accurate temperature control can be performed only when both temperatures can be regarded as the same as in a delivery vehicle.

  Next, a sensor and a passive IC tag are integrally attached to an article, and data on temperature measured by the sensor is written to the passive IC tag. With this method, it is possible to accurately perform temperature management for individual articles. However, it is necessary to attach a passive IC tag with a sensor to each individual item for which temperature management is desired, and there is a problem that the cost becomes very high. In addition, a battery for driving the sensor is generally required, and there is a problem that the battery needs to be replaced at any timing in order to reuse and use the passive IC tag with the sensor. Furthermore, since the passive IC tag with sensor itself generally has a size of several centimeters per side, there is a problem that the size of an article to be attached is limited.

Finally, an active IC tag integrated with the sensor is attached to the article, and the temperature measured by the sensor is transmitted along with ID information. This method has a feature that the degree of freedom of the system configuration on the side of reading data is higher than that of the passive IC tag with sensor. However, similarly to the passive IC tag type with sensor, when performing temperature management for individual articles, it is necessary to attach an expensive sensor-integrated active tag for each article. For this reason, there existed a problem that the cost became high, the problem of battery replacement in the case of reusing, the present condition, and the problem of being limited to the articles | goods to be attached because of a certain size.
