Investment And Research On Trouble Of Moving Freight Car Detection System (TFDS) Application In Datong-Qinhuangdao Railway Line

With the rapid development of China’s national economy, combined with the present stage of our country and the future development strategy, accelerate the upgrading of the industrial structure, improve infrastructure, improve the regional economic differences, will in the long run on a variety of natural resources have a strong and urgent demand, and this demand is further increased, the development of railway transportation requirements are also more and more urgent, heavy, large, long distance transportation organization has become an irresistible trend of railway transportation.Datong Qinhuangdao railway as the main channel of China’s coal transportation, since 2004, has been revamping, the total transportation volume hit a new high of transportation organization is also changing, has been successively CDB ten thousand tons twenty thousand tons of heavy haul train, to achieve a rapid increase transport efficiency and transport energy, corresponding to the operation of the vehicle the use of technical quality, assurance measures, technical inspection time is also put forward higher requirements.Application of railway freight cars inspection and maintenance work in China, the traditional model of long-term in the manual, only by maintenance personnel to the eye view, touch, knock, simple mode of operation, control of this model are the examiner’s technology and experience to a large extent. At the same time, this mode requires the examiner is highly concentrated, to make it work and psychological ability to bear in the long-term high load operation, it is difficult to adapt to the daily maintenance of railway vehicle request under the new situation.This paper briefly introduces the trouble of moving freight car detection system (TFDS) and the main characteristics of the working principle, and on the actual transport, using TFDS implementation of the railway vehicle inspection machine division scheme, analyzes the achievements and effects made by the TFDS. At the same time, from the two aspects of hardware and software, conscientiously sum up the car, the car lost, the picture quality existing in the operation of TFDS is not high, the system error and other issues, and put forward the improvement measures, the automatic recognition and detection etc. some suggestions on the future development direction of TFDS is also proposed to realize reduce labor intensity, to ensure the safety of transportation of the target.
