  1. Eddy - current sensor conversion circuit consist amplification circuit, band - pass filter circuit, demodulation circuit, differentiation phase and data sampling circuit. these circuits are used to convert the test signal of eddy - current sensor to discrete signal tend to process. the microprocessor system that formed of dsp chip is used to data fitting of test system, data displaying and data communicating with personal computer, etc. the interference questions of hardware design and the measure of eliminating interference signal in the subject are introduced in the last of this chapter

    硬體電路的設計主要分三大部分來實現:激勵源電路部分,由分頻電路和頻率合成電路組成,產生頻率穩定的激勵信號以確保檢測任務的正常進行;傳感器電路部分,由放大電路、濾電路、檢電路、鑒相電路和數據採集電路組成,主要將電渦流傳感器檢測線圈檢測到的信號成只含有被測信息的信號,易於后續電路處理;由dsp晶元構成的處理系統,主要完成檢測系統的數據擬合、顯示及與主機通信等功能。
  2. In the course of design, we fully consider the actual conditions on the railway and take a series of corresponding measures to the concrete problem. such as we select high - accuracy microconvertor and have the converted function in succession data collecting system chip aduc812, design v / f circuit and external a / d circuit. in anti - interference of the hardware, we try to disperse each function module to avoid interfering each other, adopt photoelectric isolated technology to dispel the circuit connection of input and output. in controlling we import arithmetic mean into strain wave algorithm and real computing technology of virtual value for sample treatment of data, that is using the software to smooth away interfere error and to calculate actual value, thus it makes the precision of the data improve greatly

    在設計過程中,根據系統要求,充分考慮鐵路上的實際情況,針對具體問題採取了一系列的相應措施,如在器件選擇方面選用高精度microconvertor系列、具有adcdma連續轉功能的數據採集控制器晶元aduc812 ,設計了v f電路和外部a d轉電路;在硬體抗干擾方面,將每個功能模塊盡量分獨立開來以避免相互干擾、採用光電隔技術消除輸入輸出通道上的電路聯系;在控制方面對于采樣數據的處理引入了算術平均值濾演算法和真有效值的計算方法,即通過使用軟體來濾除系統中有干擾造成的誤差並計算真值,從而使數據的準確性得到極大地提高。
