Technical Field

[0001] The present invention relates to the technical field of central controller testing, and in particular to a central controller testing method, device and equipment. Background Art

[0002] As the core control component of the public address system, the central controller (CCU) serves as the passenger user interface for the subway vehicle public address system. It provides passengers with operational information (such as the current route, stations, and alternate routes). It also serves as a crucial channel for driver-passenger interaction (e.g., emergency intercoms and driver announcements). With the rapid development of urban rail transit, the maintenance and testing of CCUs are crucial to the safe operation of subway trains. As subway trains age, the failure rate of CCUs increases dramatically. The shortage of spare parts severely impacts the supply of trains to the main line and disrupts external operations.
