To the device 200. Here, since the ultrasonic sensor module 102 detects an internal intrusion, that is, whether the container is opened or closed, it is preferable that one or more ultrasonic sensor modules are installed in the vicinity of the opening.

 Ultrasonic sensor module 120 is a sensor for determining the illegal intrusion of the inside of the container and the loading state of the internal goods, one or more may be installed on the inner wall of the container at predetermined intervals.

In addition, the installation position of the ultrasonic sensor module 120 is not limited to any one, and may be installed on the left and right sides of the container, the wall surface, the cover, and the like.

When data (internal state data) is received from the plurality of sensor modules 100 through the sensor wireless communication unit 204, the control unit 208, the position data of the container received through the GPS receiver 201, and Data received from the sensor modules 100 is databased and stored in the memory 205.

That is, since the memory 205 may store internal state data received from the sensor modules 100, even when communication with the server for monitoring the container state is not possible in real time, the memory 205 may be divided at once or several times when communication is resumed. The data stored in the memory 205 can be confirmed later by transmitting to the server. This solves the problem of data being discarded during periods of no communication.

The data is transmitted to the monitoring server 300 through the wireless internet unit 211, the mobile communication unit 202, or the satellite communication unit 203. That is, since the mobile communication unit 202 or the satellite communication unit 203 is included, even if a problem occurs in the Internet network, it is possible to secure a communication channel using a CDMA, GSM or satellite communication network.

 On the other hand, the smart container device 200, the interface unit 207, such as USB, RS-232, RS-485, etc., the internal state stored in the memory 205 later through the terminal connected to the interface 207 Data, operation history, and container trajectory can be checked from the outside and transmitted to external devices. This allows direct connection with external devices (PDAs, etc.) and allows container condition monitoring on site rather than in a central control room with servers.

In addition, in the case of a container that requires internal temperature control, such as a refrigeration container, a control device (freezer) for adjusting the temperature or humidity of the container may be connected through an interface unit 207, and the control unit 208, the plurality of The controller may be controlled based on data received from the two sensor modules 100, and in some cases, the operation of the controller may be controlled based on a remote control signal received from the monitoring server. . In addition, the control unit 208 can be equipped with a unique control algorithm. Therefore, if control from the server is impossible, the control algorithm is appropriately controlled by the control algorithm mounted on the basis of the data collected from the sensor modules, and after the communication resumes, the control right is returned to the server. That is, in the case of a container provided with a special device, the smart container device 200 mounted on the container may be controlled by using data collected from the sensor. In the past, only monitoring was possible, and its own control was not possible. For example, in the case of a refrigeration container, it was possible to control the freezer only directly or remotely to maintain the proper temperature by using the temperature sensed by the temperature sensor, but according to the present invention can not control or directly control the server Even if it is not possible, the smart container device 200 may control the container based on the received data.

In addition, the display unit 206 of the smart container device 200 is a display unit such as an LCD, an LED, seven segments, a lamp, and the like, so that the current state of the inside of the container can be checked from the outside.

Therefore, it is possible to receive an external manipulation and transfer it to the controller 208. This allows container condition monitoring on site rather than in a central control room with servers.

When the alarm generating unit 210 satisfies a predetermined condition, the alarm generating unit 210 may receive a signal from the control unit 208 and generate an alarm using a speaker or the like.

The wireless internet unit 211 connects the control unit 208 to the internet network 600 to communicate with the server. Wireless connectivity to readers (PDAs, etc.) enables container condition monitoring on site rather than in a central control room with servers.

The power supply unit 212 is connected to the smart container device 200 or the control unit 208, and supplies power for operating the smart container device 200. The power supply unit 212 may be a portable battery, but may include an external power interface unit for receiving external power.
