Abstract


With the rapid development of the national economy, the railway cargo transportation has become increasingly busy, Therefore, railway transportation safety is facing a more severe situation. Since long, to prevent the vehicle slipped is a very important part of railway safety. Simultaneously the railroad work station yard day by day is also busy, the vehicles’s slide accidents Increase increasingly in arrival-departure of Station, If does not adopt effective measures to prevent slip, Significant security incidents will occur, Creates the huge economic loss to the country. At present Anti-slip work of arrival-departure use generally traditional the metal shoe and the brake hand brake, Its efficiency is not high and there is a big security risk. Although in recent years, some new anti-slip devices continue to come out, But also has many flaws in the practical application, The whole automation, the intellectualized level are not high.The present paper faces up to these questions, takes the Shenshuotielu station yard’s anti-slip demand as the background, develop research of vehicle’s Anti-slip, in Developed ZT-1-type peak tail parking at the Southwest Jiaotong University foundation, Carries on the structure optimization and the promotion, Studies and designs the intelligence anti-slip system. The anti-slip system Uses Siemens S-300 series PLC, And realizes free correspondence between PLC and the superior machine free Communications through the industry ethernet, Thus realizes arrival-departure each road anti-slip brake’s automatic control、Condition monitor and fail safe. Not only increase the system’s safty and reliable, And raised the yard’s work efficiency greatly. And this paper also integrate anti-slip system into the 6502 chain-like systems, This enhances the anti-slip system’s standards, the versatility, Has brought conveniently for the system promotion, It is these superior characteristics, May cause operation accident rate of arrival-departure to reduce greatly, To realizes the railroad yard’s work automation to have the practical significance.
