As online distribution increases and distribution of logistics becomes wider and more widespread throughout the world, there is a growing interest in the distribution industry to maintain the quality of the goods during the distribution period. In addition, the market size of Korean fresh food is estimated to be about KRW 328 trillion in 2012, with the enrichment and fishery industry of 71.1 trillion won, the food manufacturing industry of 70.6 trillion won, and the wholesale and retail food industry of 186.3 trillion won. Accordingly, it is an important issue to create an environment in which the quality of fresh logistics is maintained, such as the maintenance of the logistics during transportation and the implementation of low-temperature distribution for safety.

The items to be applied in fresh logistics distribution are diverse such as food, daily necessities, chemical products, medicines, and flowers. When these products are exposed to the environment outside the specified temperature range for a certain period of time, there is a risk of deterioration such as deterioration, corruption and gaps, and a negative impact on hygiene. In order to preserve the original quality and safety, Constant temperature control and proper environment maintenance are required.

Conventionally, in order to control the quality of the fresh goods, the method of defining the expiration date by reflecting the characteristics of the goods and writing them on the commodity has been mainly used. However, according to the conventional method, in the case of the rotatable logistics, And the accuracy was not enough due to the difference of the shelf life due to the temperature condition as well as the time lapse. In addition, it has not been possible to provide high reliability in terms of easiness of operation in case of expiration date. Therefore, there is a need for a method capable of recognizing the present state of preservation of distribution according to the distribution history.

On the other hand, in the circulation of such fresh logistics, efforts have been made to maintain the quality by measuring and maintaining the temperature and humidity at each delivery unit such as a container. However, depending on the position of the cooling device, There is a problem that the quality in the delivery unit is not constant because the temperature is different depending on the position where the unit or the product is distributed.

Further, it is possible to confirm the color change even with the naked eye, so that it is user-friendly and not easy to operate, and reliability of maintaining the quality of the cargo 2 is increased.

According to one embodiment of the present invention, the discoloration portion of the temperature history indicator 1200 progresses discoloration depending on the passage of time and temperature. That is, the discoloration progresses with time, but the discoloration rate changes depending on the temperature environment. At this time, the discoloration part progresses discoloration due to the temperature experienced by the passage of time and time, and the speed of discoloration can be determined according to the temperature experienced.

The remaining validity period information can be obtained from the color change of the temperature history indicator 1200. [ Relative residual lifetime information can be obtained by visually comparing the degree of discoloration of the temperature history indicator 1200. More specifically, it is possible to obtain the relative remaining lifetime information by using a table used for estimating the remaining effective period from the discolored color value The remaining validity period can be obtained from the color. At this time, the table used for calculating the remaining validity period may be the remaining validity period table according to the discolored color value or the validity period table according to the discolored color value. In addition, the table may include information on the type of the cargo 2 or the like to which the temperature history indicator 1200 is attached, so that the table may acquire the remaining validity period differently for each type of cargo 2 and the like. The table used for calculating the remaining validity period may include the color change information when the indicator is used in the temperature history indicator 1200. [
