1. A multi-specialty virtual-reality (VR) scene verification system oriented to a smart subway, comprising a cloud server, an intelligent dispatching subsystem traffic-integrated-dispatcher-automatic-system (TIDAS), and a VR subsystem, wherein the VR subsystem comprises a VR workstation and a VR device, the VR workstation is respectively connected to the cloud server, the intelligent dispatching subsystem TIDAS and the VR device, and the VR workstation is provided with an on-board controller simulation subsystem, a three-dimensional (3D) animation simulation subsystem, and an integrated supervisory control subsystem (ISCS);
the VR workstation is configured to model according to an actual line so as to restore signals and an integrated supervisory control device of a real line, and to perform VR virtual scene demonstration; and the VR device is configured to operate a device in the VR virtual scene so as to achieve the manual system intervention, fault injection and verification of an output of the system,
wherein the VR virtual scene comprises multi-specialty typical signal devices,
wherein the multi-specialty typical signal devices comprise a vehicle, a platform door, a passenger-information-system (PIS) device, a public-address (PA) device, a signal, a beacon, a pantograph, an automatic fare collection system, a platform emergency stop button, a platform region closure button, a dispatching telephone, an emergency intercom, an on-board emergency handle, and a driver's console.
