碩士 === 大同大學 === 通訊工程研究所 === 103 === Nowadays the usage of the industrial products is very widely, not only in densely populated areas, but also in the areas where are dozens or even hundreds km far away from metropolis . In those remote areas where the network is underdeveloped or the location is quite far away from the office with network, the signals of the industrial products there can not be transmitted by network to the related unit or people who are in the distant place, for them to check if the above-mentioned industrial products work properly. In this kind of environment, if only single equipment is damaged, we could stop the industrial products and to repair it. If the system fails to work, it may put the whole system into a standstill and even cause personnel injured. In this situation, Therefore, with the usage of NFC as the media to retrieve the information in the frequency inverters, it helps to greatly reduce the inconvenience, insecurity, and distortion which are caused by written transcription. By sending the Wiced Sense of Broadcom and sending ST M24LR-Discovery with NFC respectively for test, finally It proves that NFC is more suitable in the environment of high radiation noise than the Bluetooth, because NFC is with the superior of near- field. In thesis the parameters of the frequency inverter is sent out of the chasis to NFC Tag via transmission line. Therefore we also measured the possible interference of this transmission line in this experiment, and we also research for the solution of the electromagnetic interference.
