Description

[Technical Field]

[0001] The present invention relates to a method and a system for managing a metal shielded space using multiple terminals, and more particularly to a method and a system for managing items loaded in a shielded space using terminals located inside and outside the metal shielded space. [Background technology]

[0002] A typical example of transporting and storing goods in a space shielded by metal is a container. A container is a square box-shaped container made of metal material used to transport cargo efficiently and economically. Currently, various types of loading containers are used in various industrial sites to transport large amounts of cargo more quickly. Containers make it convenient to transport various types of cargo.

[0003] On the other hand, when a container is used for export or import overseas, or when the container is loaded with goods that must be kept in a specific environment, the internal conditions of the container must be continuously managed. The problems with the conventional management system are as follows:

[0004] First, it does not take into consideration both factors inside the container and external factors. Goods loaded inside a container are affected not only by environmental factors inside the container but also by factors outside the container (such as the inflow of outside air). For example, when adjusting the environment inside a container by using a refrigerant to maintain a low internal temperature, not only can problems arise from the deterioration of the refrigerant itself (internal factor), but also from gaps between the container's door and the main body (for example, when the door is open) that allow cold air to escape to the outside, making it impossible to maintain an appropriate temperature (external factor).

[0005] Second, it is not possible to manage containers with consideration for their priority. When multiple containers are used to move goods, there may be containers that need to be managed with higher priority, and if priority is not considered, problems may arise in management.

[0006] Third, a container has an environment shielded by metal, and if a communication antenna is placed on or in contact with a metal surface, its communication characteristics will be degraded, preventing smooth communication between the outside and the inside. Summary of the Invention [Problem to be solved by the invention]

[0037] In the following, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. In the description of the present invention, the same components in the drawings are used to facilitate overall understanding.

[0038]

[0039] Throughout the specification, a terminal may be referred to as a mobile station, mobile terminal, subscriber station, mobile subscriber station, user equipment, access terminal, etc., and may include all or some of the functionality of a terminal, mobile station, mobile terminal, subscriber station, mobile subscriber station, user equipment, access terminal, etc.

[0040] Here, the terminal may be a communicable desktop computer, laptop computer, tablet PC, wireless phone, mobile phone, smartphone, smart watch, smart glass, e-book reader, portable multimedia player (PMP), portable game console, navigation device, digital camera, digital multimedia broadcasting (DMB) player, digital audio recorder, digital audio player, digital picture recorder, digital picture player, digital video recorder, digital video player, or the like.

[0041] FIG. 1 is a configuration diagram showing a management system according to an embodiment of the present invention.

[0042] 1, the management system according to the present invention includes a first terminal 100, a second terminal 200, a server 300, and a user terminal 400. The first terminal 100 is located inside a main body having a space shielded by metal, measures the internal environment, and generates data based on the measured information. The first terminal 100 may be disposed in contact with one surface inside the main body.

[0043] The second terminal 200 is located outside the main body having a space shielded by metal, measures information about the door, and generates data based on the measured information. The second terminal 200 may be located outside the main body, more specifically, in a form that contacts one surface of the exterior of the door. The second terminal 200 has a function of automatically controlling the opening / closing of the door. Meanwhile, in one embodiment, the main body having a space shielded by metal may be a container body, but is not necessarily limited to a container body and refers to a form having a space shielded by metal.

[0044] The server 300 receives data from the first terminal 100, the second terminal 200, and the user terminal 400, and combines, analyzes, and synthesizes the received data to generate data that displays the status of the main body. The user terminal 400 receives data that displays the status of the container from the server 300, allowing the user to check the status of the main body.

[0045] The first terminal 100, the second terminal 200, the server 300, and the user terminal 400 may transmit and receive data via a first network. In one embodiment, the first network may include a wireless Internet 3.5G mobile communication network such as WiFi (wireless fidelity™), a 4G mobile communication network such as an LTE (long term evolution™) network or an LTE-Advanced network, and a 5G mobile communication network. Meanwhile, the first terminal 100 and the second terminal 200 may transmit and receive data via a second network. The second network has a network structure that enables efficient data communication in a metal-shielded environment.

[0046] FIG. 2 is a flow chart illustrating a method of operation of a management system according to one embodiment of the present invention.

[0047] 2, the first terminal 100 measures environmental information inside the main body (S100). The environmental information may include temperature, humidity, pressure, carbon dioxide concentration, amount of light, and concentration of harmful gases inside the main body.

[0048] The first terminal 100 generates first data based on measured environmental information (S101). Figure 3 is a conceptual diagram specifically illustrating S101 of Figure 2. Referring to Figure 3, the first terminal 100 generates the first data taking into account one or more parameters of the measured environmental information. In this case, the first terminal 100 may generate the first data taking into account a weight value.

[0049] In one embodiment, the first terminal 100 may generate the first data as shown in the following Equation (1) by taking into consideration three parameters, namely, temperature, humidity, and carbon dioxide concentration.

[0050]

[0051]

number

[0052] where CIF 1i (x) is the first data of the x body at time i, and T i (x) is the temperature inside the x body at time i, H i (x) is the humidity inside the x body at time i, C i (x) is the concentration of carbon dioxide inside the body x at time i. WT i is the temperature weighting at time i, WH i is the humidity weighted value at time i, WC i is the concentration weighted value of carbon dioxide at time i, and WT i +WH i +WC i = 1. The first terminal 100 can appropriately change and set the weight value in consideration of the time, season, location (area), and weather at the time of measurement. 1i The larger the (x) value, the worse the condition of the main body.

[0053] Referring again to FIG. 2, the first terminal 100 transmits first data to the second terminal 200 (S102). That is, the second terminal 200 may receive the first data from the first terminal 100. The first terminal 100 and the second terminal 200 may communicate with each other in a metal-shielded environment. The first terminal 100 includes a first metal communication device, and the second terminal 200 includes a second metal communication device. To perform smooth communication in a metal-shielded environment, the first terminal 100 and the second terminal 200 may communicate via the metal communication devices.

[0054] FIG. 4 is a conceptual diagram showing a first metal communication device according to one embodiment of the present invention.

[0055] Referring to FIG. 4 , the first metal communication device 110 includes a surface unit 111, an antenna 113, and an excitation unit 115, and performs data communication using a surface wave propagating through a metal wall. The surface unit 111 contacts a metal wall that constitutes the interior of the main body. The surface unit 111 allows the first metal communication device 110 to be attached to a conductor. In one embodiment, the surface unit 111 may include a magnet, and the first metal communication device 110 is attached to the metal wall inside the main body via the magnet. The surface unit 111 can perform communication by contacting the metal wall inside the main body. Meanwhile, when the surface unit 111 is attached, a certain distance is formed between the antenna 113 and the conductor. In one embodiment, the first metal communication device 110 is attached to the conductor with a distance between the antenna 113 and the conductor so that the antenna 113 and the conductor (or the surface of the conductor) are appropriately capacitively coupled. Therefore, resonance is formed between the antenna 113 and the conductor. As a result, the conductor that has formed resonance with the antenna 113 can operate as a part of the antenna.

[0056] The antenna 113 may be disposed on the upper portion of the surface portion 111. The antenna 113 controls the resonance of the surface wave used for data communication. The antenna 113 has an impedance component. The impedance component may include, for example, a small amount of resistance component, an inductance component, and / or a capacitance component. FIG. 5 is a conceptual diagram showing an antenna according to an embodiment of the present invention. Referring to FIG. 5, the antenna 113 includes a first layer 113-1, a second layer 113-2, and a third layer 113-3. The second layer 113-2 is connected to the first layer 113-1.

[0057] The first layer 113-1 may be a conductor made of a metal material and includes a first connecting portion extending in a longitudinal direction of a predetermined unit for connection to the second layer 113-2.

[0058] The second layer 113-2 may be a conductor made of a metal material and connected to the first layer 113-1 through the first connection part. The second layer 113-2 may include a structure in which metal wires (e.g., copper wires) are wound in a spiral shape at predetermined intervals.

[0059] The third layer 113-3 may be a conductor made of a metal material and may include a second connecting portion extending in a longitudinal direction of a predetermined unit for connection to the second layer 113-2. The third layer 113-3 may be connected to the second layer 113-2 via the second connecting portion.

[0060] In one embodiment, the first layer 113-1 is 10 to 1000 mm 2 The second layer 113-2 may be a conductor having a spiral structure wound 1 to 15 times at intervals of 1 to 15 mm, and the third layer 113-3 may be a conductor having an area of ​​9 to 2500 cm 2 When the numerical range is as above, higher communication performance can be ensured in the shaded area.

[0061] The area of ​​the first layer 113-1 is 10 mm 2If the area of ​​the first layer 113-1 is less than 1000 mm , the contact area with the surface part 111 is too narrow, and the surface wave is not easily transmitted, resulting in a decrease in the accuracy ratio of communication. 2 If the area exceeds 1000 mm, the contact area will be too wide and the communication speed will be low. 2 It is preferable that:

[0062] If the interval between the spiral structures included in the second layer 113-2 is less than 1 mm, interference between conductors may occur. Conversely, if the interval between the spiral structures exceeds 15 mm, communication efficiency will decrease. Therefore, the spiral structures included in the second layer 113-2 should be 1 to 15 mm.

[0063] The area of ​​the third layer 113-3 is 9 cm 2 If the area of ​​the third layer 113-3 is less than 2500 cm, the surface impedance value will be low and communication performance will be degraded. 2 If the surface impedance is less than 9000 m / s, the surface impedance value will be low and communication performance will be degraded. Therefore, the area of ​​the third layer 113-3 should be 9 to 2500 cm / s. 2 It is preferable that:

[0064] FIG. 6 is a conceptual diagram showing an antenna according to another embodiment of the present invention.

[0065] Referring to Figure 6, the antenna 113A includes a plate-shaped pattern layer 113A-1 having at least two adjacent slits formed by openings on different sides, and having a connecting portion, a ground layer 113A-3 connected to the pattern layer 113A-1 via the connecting portion and arranged parallel to the pattern layer, and a dielectric layer 113A-2 arranged between the pattern layer 113A-1 and the ground layer 113A-3.

[0066] Here, the coupling surface of the pattern layer 113A-1 may have a length of at least one of a half wavelength and a quarter wavelength of a wavelength corresponding to a carrier frequency of wireless communication selected in the VHF band.

[0067] FIG. 7 is a conceptual diagram illustrating an antenna according to a further embodiment of the present invention.

[0068] 7, antenna 113B includes a coaxial line 113B-1, a ground plane 113B-2, and a radiation surface 113B-3. Coaxial line 113B-1, which feeds antenna 113B, includes an outer line (not shown) and an inner line 113B-1a. Ground plane 113B-2 is attached to a support, and a hole through which the inner line of coaxial line 113B-1 can pass may be formed at a first point in ground plane 113B-2. Inner line 113B-1a of coaxial line 113B-1 is led through the hole in the ground plane and contacts a second point on radiation surface 113B-3 corresponding to the first point on ground plane 113B-2, and the outer line of coaxial line 113B-1 contacts ground plane 113B-2.

[0069] The radiating surface 113B-3 may be a folded structure including a first radiating section 113B-3a, a second radiating section 113B-3b, and a third radiating section 113B-3c. Here, the first radiating section 113B-3a is arranged over a length L1 from the top of the ground surface 113B-2 to a first vertical position, which is shorter than the length from the top of the ground surface 113B-2 to the coaxial cable 113B-1a, but is arranged to be spaced apart from the ground surface 113B-2 by a first horizontal distance K1; the third radiating section 113B-3c is arranged over a length L3 from the top of the ground surface 113B-2 to a second vertical position, which is shorter than the length from the top of the ground surface 113B-2 to a support (not shown), but is arranged to be spaced apart from the ground surface 113B-2 by a second horizontal distance K2; and the second radiating section 113B-3b connects the first radiating section 113B-3a and the third radiating section 113B-3c, thereby allowing the first radiating section 113B-3a, the second radiating section 113B-3b, and the third radiating section 113B-3c to be arranged continuously. Here, the second horizontal distance K2 may be greater than the first horizontal distance K1. Here, a dielectric may be used to prevent the radiation surface 113B-3 from contacting the ground surface 113B-2 and the support (not shown). In this way, by applying a folded structure to the radiation surface, the overall height of the antenna can be reduced, allowing for the design of a small antenna.

[0070] 4 again, the first metal communication device 110 includes an excitation unit 115, which can excite the antenna 113 using a surface wave transmitted from the antenna 113. Meanwhile, the first metal communication device 110 may further include a layer including a ground plate stacked on top of the excitation unit 115. A second metal communication device (not shown) included in the second terminal 200 may also have the same configuration as the first metal communication device 110 described above.

[0071] The first terminal 100 can transmit first data to the second terminal 200 via the first metal communication device 110 described with reference to Figures 4 and 5, and the second terminal 200 can receive the first data via the second metal communication device.

[0072] 2 again, the second terminal 200 measures the status information of the open / close door (S103), and generates second data based on the measured status information of the open / close door (S104). Fig. 8 is a conceptual diagram specifically illustrating S103 and S104 of Fig. 2.

[0073] Referring to FIG. 8, the second terminal 200 can generate second data based on the number of open and closed doors, the type of open and closed doors, the number of open doors, the open / close information of the open and closed doors, and the opening and closing rate of the open and closed doors.

[0074] The number of doors is a natural number equal to or greater than 1, and the type of the doors is a value equal to or greater than 0, and may be set according to the form of the main body. For example, if the main body is a container body, the type of the doors has different values ​​depending on whether the main body is a dry container, an open-top container, a tank container, a ventilated container, or a reefer container.

[0075] The number of open doors has a natural number equal to or less than the number of open / closed doors, and the open / close information of the open / closed doors has a value of 0 (if closed) or 1 (if not closed). The open / close ratio of the open / closed doors has a value between 0 and 270. The open / close ratio of the open / closed doors is a value that takes into account the angle that takes into account the rotation range of the doors.

[0076] In one embodiment, the second terminal 200 may generate the second data as shown in Equation (2) below, taking into account the above parameters.

[0077]

[0078]

number

[0079] where CIF 2i(x) is the second data of the x body at time i, and R i (x) is the rate of opening and closing doors in the x body at time i, n is the number of opening and closing doors in the x body, k is the number of open doors, D T (x) is the type of door included in the x body, L i (x) is the door open / close information included in the x body at time i, D R (x) is (Σ n i R i (x)) / n, W i is the weighted value at time i. W i may be modified by the metallic material that constitutes the body at time i. For example, W i The lower the CIF, the more vulnerable the metal material is to the external environment. 2i The larger the (x) value, the worse the condition of the main body.

[0080] Referring again to Fig. 2, the second terminal 200 generates third data based on the first data and second data received from the first terminal 100 (S105). Fig. 9 is a conceptual diagram specifically illustrating S105 of Fig. 2. Referring to Fig. 9, the second terminal 200 generates the third data based on the first data and second data.

[0081] In one embodiment, the second terminal 200 may generate the third data as shown in Equation (3).

[0082]

[0083]

number

[0084] where CIF 1i (x) is the first data of the x body at time i, CIF 2i (x) is the second data of the x body at time i, CIF 3i(x) is the third data of the x body at time i. In this way, the third data is a composite data that takes into account the first data indicating the information inside the body and the second data indicating the information outside the body (information about the opening and closing door). CIF 3i The larger the (x) value, the higher the degree of contamination of the main body. Meanwhile, in another embodiment, the process of generating the third data may be performed by the server 300 receiving the first data and the second data from the second terminal 200 and generating the third data.

[0085] 2 again, the second terminal 200 transmits the third data to the server 300 (S106). Then, the server 300 generates a signal including information on a risk index indicating the degree of contamination inside the main body based on the third data received from the second terminal 200 (S107). Then, the server 300 transmits the generated signal to the user terminal 400 and the second terminal 200 (S108 and S109).

[0086] Fig. 10 is a conceptual diagram specifically illustrating steps S107, S108, and S109 of Fig. 2. Referring to Fig. 10, the server 300 generates a signal including risk index information and urgency information evaluated based on the risk index information, taking into account the third data. Furthermore, the server 300 generates a signal further including a command for controlling the opening and closing of the door.

[0087] CIF included in the third data 3i The (x) value indicates the degree of contamination inside the main body. The higher the risk index, the more urgently the management of the container must be carried out. The urgency corresponds to the risk index value, and the lower the number, the more urgent the required action. In one embodiment, if the risk index is 50 or more, the urgency corresponds to 0, and if the risk index is 30 to 50, the urgency corresponds to 1.

[0088] The user terminal 400 receives a signal from the server 300, so that the user can prioritize and handle the main body that needs urgent management, for example, the corresponding container. Meanwhile, the server 300 can transmit a signal to the second terminal 200 that additionally includes a command for controlling the opening and closing door. In this case, the second terminal 200 can automatically control the opening and closing door according to the command included in the signal.

[0089] FIG. 11 is a hardware configuration diagram for a first terminal according to an embodiment of the present invention.

The first terminal 100 also includes an input interface device 140, an output interface device 150, a storage device 160, etc. The components included in the first terminal 100 are connected by a bus 170 for communication.

[0091] However, each component included in the first terminal 100 may be connected via an individual interface or individual bus centered around the processor 130, rather than the common bus 170. For example, the processor 130 may be connected to at least one of the memory 120, the first metal communication device 110, the input interface device 140, the output interface device 150, and the storage device 160 via a dedicated interface.

For example, the memory 120 may be configured as at least one of a read-only memory (ROM) and a random access memory (RAM). Meanwhile, the hardware configuration of the second terminal 200 may be the same as that of the first terminal 100.

[0093] The methods of the present invention may be embodied in the form of program instructions executed by various computer means and stored on a computer-readable storage medium. The computer-readable storage medium may include, alone or in combination with other program instructions, data files, data structures, and the like. The program instructions stored on the computer-readable storage medium may be those specially designed and constructed for the purposes of the present invention, or they may be well-known and available to those skilled in the art of computer software.

[0094] Examples of computer-readable recording media include hardware devices specially configured to store and execute program instructions, such as ROM, RAM, flash memory, etc. Examples of program instructions include not only machine language code, such as that produced by a compiler, but also high-level language code that can be executed by a computer using an interpreter, etc. The above-mentioned hardware devices are configured to operate with at least one software module to perform the operations of the present invention, and vice versa.

[0095] Although the present invention has been described with reference to the embodiments, those skilled in the art will understand that various modifications and variations can be made to the present invention without departing from the spirit and scope of the present invention as set forth in the claims below.
