SWITCHING DEVICE AND METHOD FOR REALIZING PARALLEL OPERATION OF TWO OPERATING MODES OF SELF-SERVICE TERMINAL

摘要

A switching device for realizing parallel operation of two operating modes of a self-service terminal comprises a service module (10), a hardware module (20), a hardware drive module (30), a first switching module and a second switching module. When any hardware device of the self-service terminal needs maintenance, the first switching module is used for releasing the hardware device through a self-service terminal control system and unloading a dynamic library of the hardware device, and stopping operating a service unit which invokes the unloaded dynamic library of the hardware device, thereby making the self-service terminal switch to a hybrid mode of parallel operation of the limited service mode and the maintenance mode from the full-function service mode. After the hardware device has been maintained, the second switching module is used for reloading the hardware device and loading the dynamic library of the hardware device through the self-service terminal control system, and restarting operating the service unit which invokes the loaded dynamic library of the hardware device, thereby making the self-service terminal switch to the full-function service mode from the hybrid mode of parallel operation of the limited service mode and the maintenance mode.
