In addition, the product tracking system using the cold chain tracking device according to an embodiment of the present invention may further include a control unit.

In addition, the control unit may receive control information from the server 2 and remotely control the temperature inside the warehouse.

More specifically, the terminal 3 transmits control information to the server 2 based on the tracking information, and the server 2 can remotely manage and control the temperature inside the warehouse where the goods are stored through the control unit.

In addition, the terminal 3 inputs product information and transmits it to the server 2, so that the server 2 can determine the temperature at which the product is stored and determine whether the temperature inside the warehouse has changed through the control unit. . At this time, the article information may include information such as the type of article and storage temperature, but is not limited thereto. At this time, the sensor unit may further include a scan sensor to automatically grasp product information when the product is stored in the warehouse. Various sensors such as a camera sensor and an infrared sensor may be applied to the scan sensor, but are not limited thereto. In addition, the product information may be formed on the product in one form of a tag including a QR code, RFID, and NFC, and is transmitted to the server 2 through a scan sensor, so that the server 2 can grasp the product information. let it be

In this way, the server 2 not only allows the terminal 3 to grasp tracking information by monitoring the warehouse where the goods are stored in real time, but also controls the temperature of the warehouse where the goods are stored by communicating with the controller through a network. to maintain this constant temperature. In addition, the server 2 has the advantage of automatically controlling the temperature inside the warehouse according to the storage temperature of the goods by automatically identifying information on the goods through a scan sensor when goods are stored in the warehouse.

Thereafter, when the temperature inside the warehouse is not maintained constant and rises, the movable member 121 may move upward according to the increased pressure due to the gas generated inside the storage container as shown in FIG. 8(b). At this time, the movable member 121 moves upward while the movable protrusion 1213 is inserted into the movable groove 1220 while the spring 1215 is compressed. As the movable member 121 moves upward in this way, the discharge hole 123 covered by the first movable member 1211 is opened, and gas can be discharged through the discharge hole 123 . At this time, when the amount of gas generated inside the storage container 10 is less than a certain amount, the movable member 121 moves upward due to the increased pressure due to the gas, discharges the gas through the discharge hole 120, and then It can be returned to its original state as in a).

On the other hand, when the amount of gas generated inside the storage container 10 exceeds a certain amount, the moving member 121 moves to the maximum with the moving protrusion 1213 inserted into the moving hole 122, and the moving protrusion 1213 ) can be located and fixed in the downwardly curved part. Accordingly, the movable member 121 can continuously discharge the gas generated inside the storage container 10 by maintaining the state as shown in (c) of FIG. 8 and (b) of FIG. 9 .

In this way, the discharge unit 120 can discharge the gas generated from the product when the temperature inside the warehouse where the product is stored is not maintained constant, thereby preventing the storage container 10 from expanding due to the gas.

In addition, as shown in FIG. 10, by checking the upper surface of the storage container 10, it is possible to determine whether or not the temperature inside the warehouse where the goods are stored is maintained depending on whether the discharge unit 120 is operated or not.

Specifically, the moving member 121 rotates while the moving protrusion 1213 moves along the moving groove 1220 formed in an oblique shape, and as shown in FIG. 10, the rotating position of the moving member 121 can be confirmed A display means is provided so that the state of the goods can be checked.
