Type: article
Abstract: ［Objective］ In order to achieve flexible train formation function under the conditions of interconnected lines, a systematic vehicle test and verification scheme is proposed. ［Method］ Taken the interconnection and flexible formation of Beijing Metro Line 3 and Line 12 as the background, based on the design of the vehicle′s mechanical interface, electrical interface, and communication interface, aiming at three scenarios of vehicle coupling/uncoupling, reconnection operation, and interconnection/intercommunication operation, considering compatibility and scheduling requirements, a complete set of test and verification schemes are proposed, which elaborates and demonstrates in detail the verification content and necessity of various key systems and test items, and adds type test content. ［Result & Conclusion］ For the vehicle coupling/uncoupling scenario, a test verification of the coupler, TCMS (train control and management system) and on-board PIS (passenger information system) is proposed; for the reconnection operation scenario, a test verification is carried out on the traction and braking systems; in the interconnection/intercommunication operation scenario, the compatibility and linkage test verifications are carried out on the four equipment professionals of power supply, signal, communication and platform door related to the vehicle contour and external interface.
