Development of multilanguage selected automatic voice playing system based on RFID technology

Traditional oral explanation in the museums, galleries and scenic spots, is difficult to guarantee the quality requirements of the tourists, because of the language diversity and repeatability. Therefore, it is necessary to develop a multilanguage selected automatic voice playing system, which can meet different requirements of different language users for the same exhibit. The system involved in voice processing technology (voice recording and playback), RFID technology, and micro-control technology. The system can automatically determine the language of the explanation according to the needs of tourists, then it could provide tourists complete information of the exhibit, and offer them a high-definition and low-noise sound, as well. This will not only save manpower and increase efficiency, but also can fully guarantee the quality of the explanation.

Development on fuelcell voltage automatic detection system based on virtual instrument

Its necessary to measure each monomer cell voltage of the fuelcell stack in order to ensure fuelcell stack to operate normally. Therefore, a host computer monitoring management software for fuelcell voltage polling measurement based on virtual instrument programming software LabVIEW8.5 was developed. The host computer monitoring management software could show fuelcells operation voltage to user intuitively in manner of wave illustration, wave form and table through receiving fuelcells voltage parameters from client computer, and save them with TXT format based on users demand, thus it is convenient for user to inquire about fuelcells history and to analyze their status. It is proved that the automatic detection system developed can accomplish sampling, display and saving of fuelcell voltages in real-time after doing experiments on a direct methanol fuelcell.
