Such encryption and decryption are well known.

Here, the underground stress control unit 220 encrypts the transmitted message into an anti-damage packet frame 500 and transmits it to the management server 400 via the multiple wired/wireless communication unit 240, and the management server 400 also Messages, command signals, etc. transmitted to the stress control unit 220 are encrypted with the damage prevention packet frame 500 and transmitted via the multiple wired/wireless communication unit 240.

The IoT processing unit 210 of the present invention is described as being included as a component in the underground distribution line management unit 200, but is not limited thereto and may be included in the management server 400.

The damage-resistant packet frame 500 is composed of seven data field areas, for example, an overhead (OVHD) data field area 510, a first damage-resistant packet frame data field area ( 520), second damage-resistant packet frame data field area 530, third damage-resistant packet frame data field area 540, preliminary data field area 550, error check data field area 560, end head (ENHD) : end head) data field area 570 is included.

In the damage prevention packet frame 500, 1 word by digital is composed of 10 bytes by digital, and 1 byte by digital is composed of 10 bits by digital. It is very natural that the number formed by can be added or subtracted.

The reason why the number of words constituting each field of the damage-resistant packet frame 500, the number of bytes constituting each word, and the number of bits constituting each byte are different from the general structure is that an unjust third party hacks without permission. This has the advantage of preventing problems such as abuse of valuable information or damage to the information (data).

The overhead (OVHD) data field area 510 is composed of 10 words, starting point location information at which the digital data recording of the damage-resistant packet frame 500 starts, and one separated file unit data. Corresponding sequence (serial) number among a plurality of packet unit frames constituting the damage prevention packet frame 500 by file unit or by a specific title, the number of bits of digital data recorded in the corresponding packet unit frame, and damage prevention packet frame The source address information from which the first message 500 is sent, the destination address information of all nodes through which the damage-resistant packet frame 500 passes through in the process of transmission, the destination address information, and retransmission information are included and recorded.

The first damage-resistant packet frame data field area 520 is composed of 30 words and is recorded and stored in a state in which data divided into one unit file, created date and author information are linked. Here, data means data or information to be transmitted, and the same applies below.

The second damage-resistant packet frame data field area 530 is composed of 30 words and is recorded and stored in a state in which data divided into one unit file, created date and time, and author information are linked, but the first damage-resistant packet frame data field The same data as the data recorded in the area 520 is overwritten and stored.

The third damage-resistant packet frame data field area 540 is composed of 30 words, and the first damage-resistant packet frame data field area 520 and the second damage-resistant packet frame data An average value of corresponding data respectively recorded in the field area 530 is calculated and recorded and stored.

The preliminary data field area 550 consists of 30 words, and a corresponding program that is actively operated for the damage-resistant packet frame 500 is recorded and stored, and some areas (up to 80% of the area) are not used by the corresponding control signal. ) is occupied and used as an operating memory area for a buffer, and data information that is not separately defined but needs to be described is recorded and stored.

The check data field area 560 is composed of 10 words, and the address information of the current location is checked by the corresponding control signal of the actively operated program, and the source address information is searched in the overhead (OVHD) data field area 510. is checked, and the destination address information is checked by searching the end head (ENHD) data field area 570 to determine whether the address information of the current location is the same as the source address information or the destination address information.

In the check data field area 560, when it is determined that the address information of the current location is the same as the source address information by the corresponding control signal of the program being actively operated, the first damage prevention packet frame data field area 520 and the second damage prevention packet The average value of each data recorded in the frame data field area 530 is calculated and recorded in the third damage-resistant packet frame data field area 540.

On the other hand, if the check data field area 560 determines that the address information of the current location is the same as the destination address information by the corresponding control signal of the program being operated, the first damage prevention packet frame data field area 520 and the second damage prevention packet frame data field area 520 The data recorded in the anti-packet frame data field area 530 is checked for errors using the well-known cyclic redundancy check (CRC) check method and the hamming code processing method, and the generated and checked errors are recovered, that is, transmitted. If an error occurs, after recovering the transmission error, the final data of each field and the data recorded in the third damage-resistant packet frame data field area 540 are compared, and if they are not the same, the end head (ENHD: end head ) Requests that a signal (information) for requesting retransmission be recorded in the data field area 570.

End head (ENHD: end head) data field area 570 is composed of 10 words, information on the location of the end point where all data recording of the damage prevention packet frame 500 ends, and all damage prevention packets constituting a file unit. Among the plurality of unit frames of the frame 500, the corresponding sequence (serial) number is recorded identically to the overhead (OVHD). Retransmission request signal (information) is included and recorded according to departure and arrival time information at each origin, waypoint, and destination, a program that is activated and operated in the error check data field area 560, or a corresponding control signal.

In the damage-resistant packet frame 500, it is very or extremely difficult to read or decode embedded information when the configuration state of each field is not known. Therefore, the embedded information data can be protected from unjust third parties very efficiently.
