Summary: | The aircraft temperature measurement system based on the two buses comprises an upper computer, an OFDM modulation-demodulation module, a master station module and a slave station temperature measurement module. The system is simple in structure, and can achieve the multi-node temperature measurement requirement according to the actual demands of an aircraft. The anti-interference capability is high, and the system reliability is high; the OFDM technology is combined with a two-bus communication mode, so that the noise interference of the environment and the symbol interference of internal transmission are effectively resisted; address bit coding is carried out on the slave station temperature measurement module of each node, so that the temperature data of each node can be correctly identified; and the OFDM technology converts a high-speed RS-485 serial transmission mode into a multi-parallel subcarrier transmission mode, so that the transmission rate is improved to a certain extent, and the temperature info |
