Design And Implementation Of Safety Relay Electrical Characteristics Of Automated Testing

Safety relay is an important part of railway signal, its quality to the country andpeople’s life and property safety, Wenzhou7.23car accident after the railway signalsystem is be of great concern. Therefore, its electrical performance is the need forstrict quality control, all the technical indicators are qualified products can be put intouse. Thesis topic comes from the transverse project (NO.2011KJ-219), the problemhas important real significance and practical application value.For research projects, in the study of safety relay production and work on the basis ofthe characteristics, summed up the safety relay electrical characteristics of manual testmethod is insufficient, with advanced technology and equipment support, respectively,R&D DC and AC relay electrical characteristic of the automatic test system. Themain research work is:(1) the completion of the system of business analysis andfunctional requirements;(2) completed the safety relay electrical characteristicautomatic test system architecture design and implementation;(3) the design andimplementation of the DC relay electrical characteristic automatic test systemsoftware. In May1,2012and formally delivered to user. The actual field test and use,that system is stable in operation, good performance, the indicators have reached therequirements of users.
