According to the real-time speed calculation method for the motor train unit without the pure towing axle, a speed signal line is connected to an EBCU of each train through a shielding cable, and the single-train single-axle initial speed calculated by the EBCU of each train is transmitted to a TCMS through a network cable; the TCMS performs validity judgment according to the obtained data, obtains the speed of a single vehicle through comparison and calculation, and obtains the real-time speed of each traction unit through comparison and calculation; and when the real-time speed of the first traction unit is valid, the motor train unit preferentially selects the real-time speed of the first traction unit as the real-time speed of the motor train unit, and if the real-time speed of the first traction unit is invalid, the real-time speeds of the second, third and fourth traction units are sequentially selected as the real-time speed of the motor train unit. According to the method, the real-time speed of the motor train unit can be rapidly and accurately determined, the real-time speed deviation caused by the special state of the axle in the running process of the motor train unit can be effectively avoided, the method is more suitable for intelligent control of the motor train unit, and the safety and reliability of the motor train unit are improved.
一种无纯拖轴的动车组实时速度计算方法,速度信号线通过屏蔽电缆连接到各车EBCU,所述各车EBCU所计算出的单车单轴初始速度再经过网线传输至TCMS;TCMS根据得到的数据进行有效性判断、比较计算得到单车速度,再经过比较计算得到各牵引单元的实时速度;第一牵引单元实时速度有效时,动车组优先选用第一牵引单元的实时速度作为动车组实时速度,若无效,则依次选用第二、第三、第四牵引单元的实时速度作为动车组实时速度。本发明可以迅速准确的确定动车组的实时速度,并可以有效的避免动车组行驶过程中轮轴特殊状态导致的实时速度偏差,不仅更适合动车组的智能控制,更是提高了动车组的安全可靠性。
