Currently, the industry is using the MODBUS communication method, utilizing RS485 for the distributed equipment and network construction. This method has a rather good transmission and reception distance but has a disadvantage in that it is a half-duplex communication method that cannot simultaneously transmit and receive. Therefore, there is a great need for a full-duplex communication system that can simultaneously transmit and receive two-wire communications. Therefore, in this paper, we propose new communication hardware equipment that can implement a full-duplex communication method by communication signal level in order to overcome the disadvantage of communication speed when using a full-duplex communication method by time division method. The proposed communication hardware is a structure that can transmit and receive at the same time in such a way that two pieces of equipment communicating by two-wire communication can apply the outgoing signal to the same communication line and detect the received signal at the same time. Therefore, the receiving side can analyze the received signal based on the information on the current transmission signal. This signal can only be analyzed by the two communicating devices, indicating that communication security is very good.

Poetic fragmental sentences such as Haiku are often free from grammatical constraint while maintaining full message transmitting power. The author takes Haiku, a classical Japanese concise poetic sentence, as an elegant and efficient communication language for a digital signal system. By using the functional grammar and season-word ontology, the author will throw light on the secret of efficiency in Haiku-like sentences. It is often said that this efficiency comes from artistic mutism—ellipsis or abbreviation. Various events and situations are narrated in a very short and simple sentence, which is composed of a 5-7-5 pattern of letters, words, or phrases. Haiku-like sentences can be composed in non-Japanese, such as English, French, Chinese, etc. The most important Haiku philosophy is “the universality” (Fueki-Ryukou), which was first told by the great poet Basho in 1689. The benefit of universality is even ranging over the digital communication system. That is, the Haiku-like sentence enables highly efficient and concise communication. You can so much as write a cipher by Haiku.
