Abstract：With the rapid development of the rail transit technologies，MVB（Multifunction Vehicle Bus） and TRDP（Train Real-time Data Protocol） communication interfaces have become indispensable for operation of the software functions of the key communication and control devices of train such as CCU（Central Control Unit），HMI（Human-Machine Interface）and STC（System Test Controler）.At present，the software function tests based on MVB and TRDP interface devices mainly rely on manual testing，but the accuracy of the manual test method and the working intensity of these tests can’t meet any longer the need of new technologies and new equipment. Therefore，according to the study on the interface and the communication protocol of the on-board equipment of the train control and monitoring system in China，the article introduces the building and design of the automatic test platform for MVBand TRDP communication and control devices used in rail transit.This platform can improve the efficiency of software test and simplify the testing and execution process. It unifies the protocol format of MVB and TRDP，supports ordinary and complex testing actions and adopts a mature and reliable CS architecture to improve the reliability of the test platform，which allows a single client to control multiple server gateways，providing a thinking and a method for the automatic test of MVB，TRDP and other interface devices used in the current rail transit.
