In this paper, a iterative numbering protocol(Regular Sequence Numbering Protocol) for the monitoring of demage detection sheet is proposed. Demage detection sheet is one of the social infrastructures which is constructed with underground various pipe networks. The damage detection sheet is attached to the upper part of the underground facility, and is attached to provide the damage data at an early stage when the facility is damaged. Recently, it has been developed into a form that can detect when a sinkhole occurs. It is difficult to detect the demage of such a sheet by a general electric method because the distance is long (about 1.2 Km). However, if the communication distance is secured by the RS-485 standard, which is one of the communication standards, it is possible to detect the presence of demage. In addition, the noise due to various leakage currents existing in the basement is mixed with the data for damage detection through the sheet as a medium, causing multiple data corruption. In order to solve this noise problem, we propose and design an regular sequence numbering protocol with a robustness noise immunity. The proposed protocol is designed not only to detect the demage of the sheet but also to detect the communication quality of the demage detection sheet buried in the underground. The system is constructed using the 5V based Arduino and RS-485 board as the communication embedded board at both ends of the sheet. The uploading of the final data is implemented using Wi-Fi or CDMA network. |
