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連續轉換功能的數據採集微控制器晶元aduc812 ，設計了v f變換電路和外部a d轉換電路；在硬體抗干擾方面，將每個功能模塊盡量分散獨立開來以避免相互干擾、採用光電隔離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波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。 -
Some conclusions are drawn : the compressive strength and flexural strength of cubic specimens of steel fibre reinforced concrete increase with the dosage of steel fibre ; without change of dosage of steel fibre, the elastic modulus of steel fibre reinforced concrete increases with the concrete age ; steel fibre reinforced concrete is of obvious function in cracking resistance, but there is no obvious function in avoidance of cracking ; for both common concrete and steel fibre reinforced concrete, the variation of the internal temperature is different from that of the external temperature before the initial set of concrete, and the internal strain of both two kinds of concrete is great, and, in general, the variation of strain of common concrete is much greater than that of the steel fibre reinforced concrete ; after the initial set of concrete, the variation of the internal temperature of both two kinds of concrete is similar to that of the external temperature, and the variation of the internal strain is relatively small
結果表明：鋼纖維混凝土立方體的杭壓強度、抗彎強度隨著鋼纖維摻量的增加而增大；在鋼纖維摻量不變的情況下，鋼纖維混凝土的抗壓彈性模量會隨著齡期的增加而提高；鋼纖維對混凝土的阻裂作用很明顯，而對混凝土起裂的限製作用不明顯；在混凝土初凝之前，無論是普通混凝土還是鋼纖維混凝土，內部溫度的變化規律與外界溫度的變化規律不同，並且此階段混凝土內部應變的變幅很大，普通混凝土應變的變幅要比鋼纖維混凝土應變的變幅大得多；在混凝土初凝之後，無論是普通混凝土還是鋼纖維混凝土，內部溫度的變化規律與外界溫度的變化規律相同，並且此階段混凝土內部應變的變幅很小。 -
