<P>PROBLEM TO BE SOLVED: To control environment situation for an article and prevent deterioration of the article. <P>SOLUTION: In this system, a radio tag 1 has an IC chip 2, an antenna 3, and a temperature sensor 4. Distinguishing information of the article to which the radio tag is attached and environment conditions are written in a storage part of the IC chip 2 in advance. This radio tag 1 is bonded to the article. A reading device 6 is provided with an antenna 7 and an IC chip 8. The reading device 6 decodes information transmitted from the radio tag 1 in a decoder part 8a, determines the decoded result in a determining part 8b, and transmits distinguishing information of foods and environment conditions to an environment controller 10 by wire line. The environment controller 10 controls a motor 12a for a compressor of a cooling device which is environment control instrument through an inverter circuit 13 in accordance with information given from the reading device 6. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
