Research On The Engineering Project Of Detection And Application In Diesel Locomotive And Electric Locomotive

In this thesis , the author research some of insufficient developments of the locomotive relying on the nearly 18 years experience in the Locomotive service section, analysis original system existence questions, proposes the improvement program, and develops the corresponding installment. The installment applies actual center, had achieved the anticipated target, got up the good society and the economic efficiency. The main research works of this thesis have the following several aspects:SS4 electric locomotive odd and even festival fast excision installment development. In view of high efficiency locomotive SS4 cannot in the malfunction excision single-node question, develop SS4 to change the electric locomotive odd and even festival fast cut installment, has realized in the breakdown situation fast single-node excision, big reduction machine broken probability.DF4 diesel locomotive electricity transmission control circuit failure detection and automatic reduction installment development. Partial frequently breaks down in view of the DF4 locomotive electricity transmission, the breakdown cannot promptly remove the causing machine broken present situation, develops the DF4 diesel locomotive electricity transmission control circuit failure detection and the automatic reduction installment development, can the fast breakdown localization and can the automatic emergency processing breakdown maintain the locomotive the movement.Locomotive rate signal synthesis treating plant development. Is unstable in view of the diesel locomotive and the electric locomotive velocity generator, directly affects the locomotive control and the train movement security monitor normal work question, develops the locomotive rate signal synthesis treating plant, can synthesize the multichannel velocity generator signal, analyzes the signal breakdown circuit, when minority sensor for breakdown still could give the control system to provide the rate signal, maintained the locomotive the normal operation.Locomotive Scatters sand controller development. After the original locomotive Scatters sand control apply the brake to cause massively Scatters sand, goes into storage when the locomotive with the storehouse experiment also must many times Scatters sand, not only can cause the granulated substance waste, increased has swept clear the work load, came seriously when interfered with the track circuit normal work, created the collision accident. For this development locomotive Scatters sand controller, can act according to the actual situation limit sander movement, reduced not essential Scatters sand.The above development installment all sets up the item by the project form by the Wuhan Railroad Bureau sub-bureau, the project has all completed and through the Wuhan Railroad Bureau science and technology achievement appraisal, SS4 electric locomotive odd and even festival fast excision installment development and the locomotive Scatters sand controller in actual center has promoted the use, the use effect is good.
