LINE MULTIPLEXING APPARATUS AND ENGINEERING MACHINERY

摘要

A line multiplexing apparatus comprises an input multiplexing circuit board (106) and a controller (102). The input multiplexing circuit board (106) comprises a plurality of first input ports and at least one first output port, and the plurality of first input ports is connected to corresponding signal sources (108) respectively. The controller (102) sends a signal source selection command to the input multiplexing circuit board (106) based on a current real-time condition. The input multiplexing circuit board (106) selects the first input port based on the signal source selection command sent by the controller (102), and conducts a signal transmission line between the selected first input port and the corresponding first output port to obtain corresponding signals. Further proposed is engineering machinery comprising the line multiplexing apparatus. The present invention can reduce the line complexity and meet application demands of multiple ports, thereby optimizing resource utilization and reducing the system cost.
