Abstract

The invention discloses a testing device for a passenger information system of a rail transit system, and the testing device comprises a main control module, a vehicle simulation module, an intelligent model module, a storage module, a protocol monitoring module, and a switcher which is used for the data interaction with terminal equipment in the passenger information system. The vehicle simulation module is used for collecting MVB bus data of a passenger information system from the terminal equipment through the switcher and generating a test model. The intelligent model module is used for editing a train operation model and a test plan; the storage module is used for storing a test plan, a test case and corresponding test data; the protocol monitoring module is used for monitoring data sent from terminal equipment in the passenger information system so as to detect whether the data meet protocol regulations or not. The testing device for the passenger information system of the rail transit system is suitable for testing the passenger information system, and reduces manpower and material resources consumed by construction of a testing environment and implementation of a testing process.

Description

technical field [0001] The invention relates to a test device for a passenger information system of a rail transit system. Background technique [0002] The on-board passenger information system of the subway train provides voice broadcasting, emergency alarm, station information display, multimedia information playback for passengers, and broadcast intercom and video monitoring for crew members. Passenger information system generally includes three subsystems, which are train public address (PA) system, information display (IDS) system and video surveillance (CCTV) system. In addition, it also includes interfaces with other systems (such as interfaces with TCMS systems, wireless communication systems, and digital televisions, etc.). [0003] With the development of subway technology, the on-board passenger information system of subway trains tends to adopt the framework system of all-digital Ethernet. Although the physical structure has been simplified and the interface o...
