Electric Locomotive (emu) Preparedness Operational Safety Of Associated Control Computer Systems Research And Practice

With the development of electric railway construction and improvement of its speed in our country, electric locomotive and EMU has rapidly been the major traction and transportation instrument. During the servicing preparation, the importance is how to guarantee the safety of the operator and the equipment. However, here is unsafe factors existed in the traditional operation method, such as low efficiency, hard strength etc., so it must be improved quickly.To meet the requirement of Electric Maintenance Section, Guangshen Company, based on the present detective techniques in servicing preparation at home and abroad and the demand of the net techniques, The central controlling system and the net controlling system was designed with the PLC as controlling operation unit. To fit the situation of the EMU servicing preparation, such as large-sized area, more distribution of interlock switch and far distance etc, The IC managing system was developed, with automatic power grid protection signal of interlock switch. The writer finished the whole system programming.The central management control of disconnecting in servicing preparation can effectively prevent from the malfunction and unsafe factors in rainy season, guarantee the safety of operator in electrical network ground; the state of interlock switch refrain from getting an electric shock by man-made; the special access device to the top working simplify the working process and guarantee the safe of repairman; the switch of photoelectric conductor repairing can protect the isolation switch operation from electric operationThe developed system has changed the traditional management and detective model in electric locomotive. The advantages of saving the operation time and improving the efficiency provide the technology supervision in railway security production.
