【摘要】：為了提高光纖傳感器系統(tǒng)的檢測質(zhì)量,設(shè)計并實現(xiàn)了智能光纖傳感器系統(tǒng)。首先采用光纖將輻射傳遞到光電二極管,并通過該管輸出信號,實現(xiàn)光電變換。然后采用模數(shù)A/D變換器將電信號變換成數(shù)字信號,向P89C668單片機輸入數(shù)字信號后通過軟件對物體進行動態(tài)調(diào)整。最后采用數(shù)字模擬變換器將信號變換成電壓信號輸出,實現(xiàn)了CAN總線通訊接口設(shè)計與傳感器系統(tǒng)的組網(wǎng)。結(jié)果表明,該系統(tǒng)的檢測誤差低于1℃,可對光源進行平穩(wěn)控制,具有較高的抗干擾性。
[Abstract]:In order to improve the detection quality of optical fiber sensor system, an intelligent fiber optic sensor system is designed and implemented. Firstly, optical fiber is used to transmit radiation to the photodiode, and the output signal is realized by the output signal of the diode. Then the analog-digital A / D converter is used to transform the electrical signal into a digital signal, and then the digital signal is input to the P89C668 single-chip computer, and then the object is dynamically adjusted by the software. Finally, the digital analog converter is used to transform the signal into voltage signal output, and the design of communication interface of CAN bus and the networking of sensor system are realized. The results show that the detection error of the system is lower than 1 鈩，
