Specifically, the data storage unit 200 stores the data in the automatic control information storage unit 220 when the data received from the network communication unit 120 is automatic control information, and the data when the received data is smart farm sensor information May be stored in the sensor information storage unit 230. The data storage unit 200 may perform the above-described classification operation by checking a data tag of data received from the network communication unit 120. To this end, the network communication unit 120 may attach an appropriate data tag according to the type of received data before transmitting the data to the data storage unit 200.

The security module 300 may perform a function of encrypting or decrypting data in the smart farm black box 10. For example, the security module 300 may encrypt the smart farm control information received by the data receiving unit 100 and transmit it to the database 200. Details on encryption and decryption through the security module 300 will be described later.

According to an embodiment of the present invention, the relay line receiving unit 110 and the network communication unit 120 may respectively receive manual control information and automatic control information. Accordingly, when a user directly manipulates the smart farm control unit 20 or when the smart farm control unit 20 generates a control signal by a preset algorithm, control information may be stored in the smart farm black box 10. Therefore, according to the present invention, since control information can be stored in the smart farm black box 10 without missing, data integrity is excellent.

In the above, data communication between the smart farm black box and an external device was examined. Hereinafter, a method of processing data inside a smart farm black box will be described.

3A and 3B are diagrams illustrating a method of classifying data of a smart farm black box and an output screen of the classified data according to an embodiment of the present invention.

According to FIG. 3A, it is possible to check the smart farm control information (CD) and the classified smart farm control information (CD-S).

The smart farm control information (CD) may be manual control information or automatic control information. The smart farm control information (CD) may include various types of information. For example, the smart farm control information CD may include first control information DT-1, second control information DT-2, and third control information DT-3. The first control information DT-1, the second control information DT-2, and the third control information DT-3 are any one of an operation time, a control name, a control mode, an operation, a connection method, and an opening rate. And different types of information.

Information tags for data classification are attached to each of the first control information DT-1, the second control information DT-2, and the third control information DT-3 included in the smart farm control information CD.

Prior to storing the smart farm control information CD in the data storage unit, the smart farm control information CD may be classified according to an attached information tag. Specifically, the data storage unit may classify the data by checking whether the information tag and the data extraction parameter correspond. For example, the data storage unit may include a first data extraction parameter to a third data extraction parameter PR-1, PR-2, and PR-3. Each of the first to third data extraction parameters PR-1, PR-2, and PR-3 is a first control information tag (TG-C1), a second control information tag (TG-C2), and 3 Corresponds to the control information tag (TG-C3).

Accordingly, the user can easily check information included in the control information received at an arbitrary point in time, and can easily check whether or not an abnormal operation has been performed by arranging data according to desired parameters.

4A and 4B are diagrams illustrating a method of classifying data of a smart farm black box and an output screen of the classified data according to an embodiment of the present invention.

According to FIG. 4A, smart farm sensor information SD and classified smart farm sensor information SD-S can be checked.

The smart farm sensor information SD may also include a plurality of different types of sensor information and a plurality of different types of information tags similar to the smart farm control information CD. For example, the smart farm sensor information SD may include first sensor information DT-4, second sensor information DT-5, and third sensor information DT-6, each of which A first sensor information tag (TG-S1), a second sensor information tag (TG-S2), and a third sensor information tag (TG-S3) may be attached. At this time, the first sensor information tag (TG-S1), the second sensor information tag (TG-S2), and the third sensor information tag (TG-S3) are the above-described first control information tag (TG-C1), It is different from the 2 control information tag (TG-C2) and the third control information tag (TG-C3).

Prior to storing the smart farm sensor information SD in the data storage unit, the smart farm control information SD may be classified according to an attached information tag.

In the above, we have looked at how smart farm control information and smart farm sensor information are classified in the data storage unit. Smart farm control information and smart farm sensor information can be encrypted in a security module prior to being classified and stored. Hereinafter, a method of encrypting and decrypting smart farm control information and smart farm sensor information in the security module will be described.

In this embodiment, for convenience of description, the term data receiving unit 100 is used as a generic term for a relay line receiving unit and a network communication unit.

The security module 300 may encrypt the received smart farm control information and/or smart farm sensor information using the encryption key table. In this case, the security module 300 may include at least one encryption key table, and accordingly, data received at different times or different types of data may be encrypted by different encryption key tables. For example, the security module 300 may include a first encryption key table EN1 and a second encryption key table EN2, and the first encryption key table EN1 stores data received at a first time point. It is used for encryption, and the second encryption key table EN2 may be used to encrypt data received at a second time point different from the first time point. The first encryption key table EN1 and the second encryption key table EN2 may be a one-time variable encryption key table generated from a variable authentication key.

The security module 300 may encrypt data through a modified AES128 encryption scheme.

Since encrypted information is stored in the database 200, security of smart farm control information and/or smart farm sensor information may be improved. Accordingly, even if a third party extracts smart farm control information and/or smart farm sensor information from the database 200 without permission using a removable storage or the like, it may be difficult to interpret the encrypted information.

The encrypted smart farm control information and/or smart farm sensor information stored in the database 200 may be transmitted to the output device 80 according to a user's request. The output device 80 may be of various types, such as a mobile device and a PC. Before transmitting the smart farm control information and/or smart farm sensor information to the output device 80, the encrypted smart farm control information and/or the smart farm sensor information may be decrypted in the security module 300.

Accordingly, information stored in the first smart farm black box 10a, the second smart farm black box 10b, and the third smart farm black box 10c may be backed up through the cloud server CS. In addition, the first smart farm black box 10a, the second smart farm black box 10b, and the third smart farm black box 10c remove the information backed up from the cloud server CS, thereby You can reduce the amount of storage.

The first smart farm black box 10a, the second smart farm black box 10b, and the third smart farm black box 10c may receive data from the cloud server CS as needed. For example, data removed from the first smart farm black box 10a, the second smart farm black box 10b, and the third smart farm black box 10c can be transferred from the cloud server CS according to the user's request. Data can be received in the form of download.

The cloud server CS may be provided in various forms, such as Infrastructure as Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

The cloud server CS may be connected to multiple smart farms at the same time. The cloud server CS provides a unique ID for each connected smart farm, so that a plurality of smart farms can be simultaneously connected to the cloud server CS.

The cloud server CS may be connected to the cloud database DB. Accordingly, data stored in the cloud server CS is stored in the cloud database DB, and the cloud server CS loads and transmits appropriate data from the cloud database DB according to a user request.

The cloud server CS may be connected to the user terminal MD. The user terminal MD may access the cloud server CS to control the smart farm or receive necessary information related to the smart farm.

The user terminal (MD) may be a device having an output function and a communication function such as a mobile phone, PDA, PC, laptop, or tablet PC to perform the above-described functions.

Through the user terminal MD, the user can access the cloud server CS. At this time, the user may request permission to access the cloud server CS by transmitting the user access information assigned to the user to the cloud server CS. The cloud server CS may allow or block user access by checking whether the stored user access information and the user access information received from the user terminal MD match.

Using the user access information transmitted from the user terminal MD, the cloud server CS may connect a specific smart farm among the plurality of smart farms with the user terminal MD. The user terminal MD may send a control signal to the connected smart farm through the cloud server CS or receive information related to the connected smart farm through the cloud server CS. Accordingly, it is possible to control and monitor the smart farm even when the user is away from the smart farm.

According to an embodiment of the present invention, data management and smart farm management are very easy as the smart farm and the user terminal (MD) are connected through the cloud server (CS).

In the above, the connection type between the smart farm and the user terminal by the cloud server (CS) was examined. When a plurality of smart farms and cloud servers are connected, the cloud server may perform an authentication procedure to prevent user terminals from controlling irrelevant smart farms. Hereinafter, this authentication procedure will be described.

9 is a block diagram showing a method of operating a smart farm system according to an embodiment of the present invention.

According to FIG. 9, first, a cloud server receives data from a smart farm black box (S100). As described above, the data reception method may be performed in a wired or wireless communication method. The data received by the cloud server may be smart farm control data and/or smart farm sensor data.

Next, the cloud server may tag the received data with a black box ID. The black box ID may mean identification information assigned to the smart farm black box. The black box ID can be provided in various forms, such as the Mac address of the smart farm black box.

Next, the data tagged with the black box ID may be encrypted (S300). In this case, encryption may be performed in a cloud server or an external database connected to the cloud server. Encryption methods can be various, such as public key method and block chain method. When data is encrypted using the blockchain method, multiple smart farm black boxes connected to the cloud server can participate in blockchain authentication. The encrypted data may be stored in the cloud server or in an external database connected to the cloud server.

Next, when there is a request for access from the user terminal, the cloud server checks the user access information received from the user terminal (S400). User access information may be provided in the form of an ID and password, and the cloud server may check whether the stored ID and password match the ID and password received from the user terminal. If the user information received from the user terminal does not match the user information stored in the cloud server, the cloud server may reject the user's access.

Next, the cloud server can check whether the user access information and the black box ID match. Specifically, the user access information may include information on a specific smart farm black box ID, and the cloud server can check whether there is a black box ID that matches the smart farm black box ID included in the user access information.

If there is a smart farm black box with a black box ID that matches the black box ID included in the user access information among the smart farm black boxes connected to the cloud server, the cloud server connects the user terminal and the corresponding smart farm black box.

At this time, for example, data tagged with a black box ID may be loaded from a cloud server or an external database (S600).

If there is no smart farm black box that has a black box ID that matches the black box ID included in the user access information among the smart farm black boxes connected to the cloud server, the cloud server checks the user access information again and reconnects the user to the user terminal. You can request information.

Accordingly, it is possible to prevent a third party from accessing an irrelevant smart farm black box and stealing information or controlling the smart farm without permission.

After the data tagged with the black box ID is loaded from a cloud server or an external database, the data tagged with the black box ID may be decrypted (S700). The user terminal receives the decoded data and can check the data through the user terminal accordingly.

According to an embodiment of the present invention, even when a plurality of smart farms are connected to a cloud server, the cloud server is connected to the smart farm by only authorized users through an authentication procedure, thereby improving the security of the smart farm.
