Malfunction Analysis And Solution Optimization Of Transmission Equipments In Subway Systems

The travel pressure in Beijing increased rapidly followed by the fast growing population of Beijing.This made subway an important travel facility in the daily life of people in Beijing.It bare more and more important travel functions.In the recent years the development of the Beijing subway is in a fast progress.It added more travelling direction lines and gained significant results.In the everyday work,the communication facility directly determines thesafety of the subway operation,and it thus relate highly to the life safety of the citizens in Beijing.As the level of complexity of the commucation facility and the operation hours increase,the chance of a malfunction also increase.How to effectively and sort out the facility malfunction is an important topic to examine.This thesis mainly research and examine the question of the malfunction and facility improvement of the subway transportation facility and the wireless facility,data experiment of the average malfunction time consumption,the cost of sorting out accident,the possibility of malfunction occur,as well as analyse the malfunction.To conclude a new solution by analysing and examine the traditional solution,as well as get a better solution and update and improve the way to teast malfunction.This thesis eventually sort out the malfuctions occured as a result of improving battery facility through the update of the communication transportation facility and the analyse of the the malfunction of the wireless facility,the analyse and update of the malfunction of the decision function of the transportation path,the light board,the metal tube,the wireless station and theconnection of the image and video with transportation facility to sort out the malfunction which occured throught the upgrade of the battery facility.The thesis introduced the origin of the problems occured or est new sorts and methods of research through the analyse of themalfuncton,using the experimental data experimental outcome to illustrate the advantages and disadvantages of thesolution method.In the base station fault processing,the number of people handled in each failure will be reduced in the new scheme saving the labor cost.Also,the number of equipment needing to be replaced will be reduced when the failure happens every time in the new scheme saving the operation cost.In the power transformation project,the problem of fault transformation will be solved in the new scheme.
