| With the rapid development of science and technology, In many areas, the increasingly high demand for sensors, The traditional sensor has failed to meet current needs. FBG sensors have many advantages,such as Light weight, small size, long life, high accuracy, corrosion resistance, anti-electromagnetic interference, flexible and convenient and so on. Became one of the hot research field.The purpose of this paper is to develop a design of novel FBG sensors, which can be high-precision, highly sensitive reflect the object’s strain and temperature changes, In terms of measurement accuracy achieved a technological breakthrough. Using a broadband light source and complete the whole mechanism of the filter, achieve the practical standards, To fill the gap in the market for such products. The system changes the axial stress to complete Fiber Bragg Grating periodic changes in the refractive index values. So as to achieve the purpose of changing the reflected wave field. using the precision digital drive stepper motor to compress the raster which can achieve high-precision tuning. High speed microprocessor to calculate acquisition the data and display. The system has high accuracy, good stability.The system transplanted uCos-ii real-time multi-tasking operating system, for the development and expansion of the system provide a great convenience and Shorten the development cycle. Comparing with traditional SCM development, the system enhance system reliability and debug easier. The main contents of this paper as follows:1、According to the project’s needs, design the whole system configuration. 2、According to demand, designing the Fiber Bragg Grating sensor system’s hardware circuit、software、adjustment mechanism and part of the optical path.3、Achieving the precision Fiber Bragg Grating’s sampling and control Function.4、Achieving the wavelength locking function5、Achieving the precision Fiber Bragg Grating’s instrumentation work and promotion of human-computer interaction. |
