Abstract

The invention relates to a module identification acquisition system and a method thereof. The module can be connected with the address single board in a pluggable manner. The address single board comprises an address signal generating unit, and the module comprises an excitation generating unit and an address processing unit. When the module is plugged into the address single board, the excitation generating unit provides a first path of voltage excitation signal and a second path of voltage excitation signal for the address single board. The address signal generating unit generates a first feedback voltage signal representing the slot position address spliced by the module based on the first path voltage excitation signal, and generates a second feedback voltage signal representing the group address set by the address single board based on the second path voltage excitation signal. The address processing unit determines an identity mark comprising a slot address and a group address of the module based on the two feedback voltage signals, and sends the identity mark to the main controller. The main controller establishes communication connection with the corresponding module based on the identity. The invention can dynamically acquire the identity of the new inserted module in real time and report the identity to the main controller.
