The sealing unit 100 may seal the object to be sealed and detect whether it is damaged.

For example, the sealing unit 100 may be installed on the door of a cargo container and used to seal it. In addition, it can be installed and used in various places where sealing is required, including warehouses, safes, and travel bags in addition to cargo containers.

The sealing part 100 includes a wire 110 and a wire shaft 120.

The wire 110 seals the sealing object. For example, the sealing object may be sealed by being inserted into a hole provided in a door or a handle of a cargo container and fastened.

A break detection conductor is provided in the center of the wire 110 along the length direction of the wire. A minute current flows through the breakage detection wire. If the wire 110 is cut by an external force during theft or abnormal opening/closing attempt, the breakage detection wire is also cut. Since current does not flow through the cut breakage detection wire, it is possible to detect whether the wire 110 is cut or broken.

The wire shaft 120 binds the wire 110 and the main body of the electronic sealing device 10.

The wire shaft 120 includes a first wire shaft 121 and a second wire shaft 122.

After receiving the sealing release signal, the release unit 200 determines whether or not it matches the previously registered release signal, and releases the sealing of the sealing unit 100 if the same.

The release unit 200 includes a release signal reception unit 210 and a release signal suitability determination unit 220.

The release signal receiving unit 210 receives a release signal for releasing the seal.

For example, the release signal receiving unit 210 may include at least one of an NFC card reader, a keypad, a pattern input pad, a biometric information recognizer, and a release command receiver receiving a release command received by the communication unit.

The release signal suitability determination unit 220 compares the release signal received through the release signal receiving unit 210 with a previously registered release signal. If the two signals match as a result of the comparison, the sealing part 100 is released.

That is, when an NFC card reader is provided, a user who has the right to release the seal may bring the NFC card and release the seal by tagging it with the release signal receiving unit 210. In addition, when a keypad or pattern input pad is provided, the seal may be released by inputting a previously registered password or pattern. In addition, when a biometric information recognizer is provided, the seal may be released through a method such as fingerprint recognition, voice recognition, iris recognition, and face recognition. In addition, when a seal release signal is received from an external server or external device under the control of the administrator, the seal can be released.

The status display unit 300 emits a blue light indicating entering the data transmission/reception mode for 5 seconds, and simultaneously generates an alarm sound.

When the NFC card is brought to the release signal receiving unit 210 before the blue light is turned off, the alarm sound and the blue light are turned off at the same time as the vibration, and the sealing of the sealing unit 100 is released.

Next, when the wire 110 of the sealing unit 100 is separated from the main body of the wire shaft 120 and the electronic sealing device 10, the electronic sealing device 10 enters the GPS search mode to determine the current location. do. The status display unit 300 emits a green light indicating that the GPS search mode has been entered.

When the green light turns off after the GPS search is complete, the electronic sealing device 10 enters the data transmission/reception mode once again and transmits to the management server that the current location and the NFC card are tagged, and at this time, the status display unit 300 once again lights the blue light. Glow.

Thereafter, after the current location and data transmission indicating that the NFC card is tagged are completed, the blue light of the status display unit 300 turns off and waits until the next operation.

The location determination unit 400 determines the current location of the electronic sealing device 10, and stores and manages a scheduled movement path and a location movement history.

The location determination unit 400 supports a global navigation satellite system (GNSS) including GPS, a satellite navigation system developed and managed in the United States, and GLONASS in Russia. Hereinafter, among these, GPS is used as an example.

The location determination unit 400 can track the real-time location of the container and the cargo through the GPS signal, and through this, can check the location movement history. In addition, it is possible to determine whether the operation is normally performed by comparing the previously stored planned movement route with the location movement history determined through real-time location tracking.

The location determination unit 400 may store a transport plan and a planned movement route of the cargo. For example, the origin and destination of the cargo can be stored.

The origin and destination are specified through latitude and longitude input. At this time, a radius of a certain range from the origin and destination may be designated together. The location determination unit 400 determines the current location of the electronic sealing device 10 through a GPS signal. If the current location is outside a preset radius from the departure point, it can be seen that the cargo has departed, and the current location is preset from the destination. If you are inside the radius, you know that the cargo has arrived.

In addition, in addition to inputting a departure point and a destination, a planned moving route may also be stored. A plurality of scheduled stops may be set in the middle of the scheduled travel route, and the electronic sealing device 10 may inform the management server whenever the bound cargo passes the scheduled stop. This allows the manager to confirm that the cargo is moving safely along the planned route. In addition, through the distance and elapsed time between the previous stopover and the latest stopover, it is possible to infer at what speed the current cargo is moving.

In addition, the location determination unit 400 may send a warning or a notification to an external server or device through the communication unit 600 when the current location is out of a preset distance from the previously input starting point, destination, stopover, and planned movement route. .

The attachment part 500 allows the electronic sealing device 10 to be attached to the sealing object.

The attachment part 500 may be provided on the rear surface of the body of the electronic sealing device 10. For example, the attachment part 500 may be provided as a neodymium magnet and attached to the container through magnetic force. The electronic sealing device 10 attached to the container through the attachment part 500 may be stably attached to the container even if the ship or truck shakes during movement.

The communication unit 600 transmits and receives data to and from an external server or device.

The communication unit 600 is responsible for transmitting and receiving data between an external server including a management server or an external device including a mobile terminal of an administrator and the electronic sealing device 10.

The electronic sealing device 10 of the present invention may include an image management unit 700, a voice management unit 800, and an impact detection unit 900.

The voice management unit 800 acquires information on a surrounding voice pattern and compares it with a previously stored voice pattern.

In some areas of the electronic sealing device 10, a voice collecting device for collecting surrounding voice information is provided. The voice management unit 800 records voice patterns of people who are allowed access. Therefore, if a voice pattern different from a previously stored voice pattern is recorded among voice patterns collected through the voice collection device, the voice patterns are separately stored and managed.

The impact detection unit 900 detects an impact applied to the electronic sealing device 10.

Sensitivity, which is a reference when detecting an impact, can be adjusted according to the user's settings. For example, if the sensitivity is set low, a small impact is not given an impact rating and is treated as not receiving an impact. Of course, it is also possible to set the sensitivity high so that even a small impact can be recognized as being shocked.

The image management unit 700 controls the photographing device to acquire image information, and stores and manages it.

The image management unit 700 includes a photographing unit 710, a photographing control unit 720, and an image processing unit 730.

The photographing unit 710 is attached to the body of the electronic sealing device 10 to acquire a surrounding image. For example, the photographing unit 710 may be applied without limitation as long as it is an image photographing device including a digital camera, a video camera, and the like.

The photographing control unit 720 controls the operation of the photographing unit 710.

Basically, the capturing control unit 720 controls the capturing unit 710 to acquire an image at every preset time interval. For example, the capturing control unit 720 may control the capturing unit 710 to acquire an image every 5 minutes.

In addition, the capturing control unit 720 may control the capturing unit 710 to additionally acquire an image in the following cases.

For example, when a sealing release signal is received through the release unit 200, when the communication connection between the electronic sealing device 10 and the management server is disconnected, the sealing unit 100 is damaged, and thus the wire 110 is damaged. When the sensing wire is damaged together, when a sealing release signal is input to the release unit 200, or the position of the electronic sealing device 10 through the position determination unit 400 exceeds a preset range and deviates from the predetermined movement path If it is determined that there is one, the photographing unit 710 may be controlled to additionally acquire an image.

In addition, in addition to the above cases, the photographing control unit 720 detects motion in the image acquired through the photographing unit 710, if a shock exceeding a preset range is detected through the shock detector 900, or When a voice pattern other than a previously stored voice pattern is detected through the voice management unit 800, the photographing unit 710 may be controlled to additionally acquire an image.

The image processing unit 730 stores, converts, and manages an image photographed through the photographing unit 710.

Basically, the image processing unit 730 converts a pre-stored image into a low-resolution image at preset time intervals and transmits it to the management server together with current location information. For example, an image captured through the photographing unit 710 may be transmitted to the management server every 10 minutes.

In addition, the image processing unit 730 transmits the previously stored image to the management server at preset time intervals, and compares the latest image acquired through the photographing unit 710 with the previously stored image to find a difference. The latest video together with the current location information can be additionally transmitted to the management server.

Thereafter, when a request for a high-resolution video is received from the management server, the original video of the video is retransmitted. For example, when a management server finds a specific item in a specific image and determines that more detailed observation is necessary, the image processing unit 730 may request to transmit a high-resolution image, and the image processing unit 730 You can retransmit the high-definition copy of the document to the management server.

The operation of the image processing unit 730 can effectively reduce an increase in data throughput and power loss in data processing by transmitting a high-definition image to an external server or an external device in real time.

When the image processing unit 730 controls the photographing unit 710 through the photographing control unit 720 to obtain an additional image, the image processing unit 730 determines whether a person exists in the additional image. If a person is included in the acquired image, only an image of an area corresponding to a person is extracted from the entire image, and a list of people of interest is generated and managed.

In addition, the image processing unit 730 may store an image of a person who is permitted to access each location. For example, an image of a person who is permitted to access in the Busan area, an image of a person who is permitted to access in the Seoul area, and an image of a person who is permitted access in the process of moving from the Busan area to the Seoul area may be stored separately. .

Thereafter, the image processing unit 730 compares the image of the person registered in the list of interested persons with the image of the person authorized to access by location. If it is determined that the same person as the person who is permitted to access by location has approached, the image of the person is removed from the list of people of interest.

For example, when a container cargo is loaded on a truck and moved from Busan to Seoul, a face image of a truck driver may be obtained through the photographing unit 710. The image processing unit 730 registers a face image of a driver of a corresponding truck in a list of people of interest. However, if the truck driver's face image is registered as an image of a person who is permitted access during the process of moving from Busan to Seoul, the truck driver's face image is deleted from the list of people of interest.

This list of interested persons is to facilitate identification of outsiders by quickly checking only the corresponding list when it is confirmed that the electronic sealing device 10 is damaged and the internal goods have been stolen.

In addition, by organizing the video information captured through the image management unit 700 and the audio information recorded through the audio management unit 800 by time slot, it is possible to more easily identify the identity of unauthorized personnel who have access to the electronic sealing device 10. Make it possible.
