4 个工业显示器（17”）装在防爆壳里，DN12 软管铺有光缆用来连接采煤机和久益顺槽通信控制 系统（JOS）。 Connection to provide Ethernet data and video out to surface PC 将 Ethernet 数据和视频传输到地面计算机的连接装置。 Transceiver and aerial mounted to control the Shearer from the JOS 通过 JOS 控制采煤机的收发器和天线。 Advanced Shearer Automation(ASA) including Proportional Control 智能切割，包括比例阀控制 Advanced Shearer Automation (ASA) is a fully automated shearer cutting program. ASA permits the user to design complete cutting sequences for their longwall face profile offline, which includes gate end cutouts. An offline tool, referred to as GOLP (Graphic Offline Planner), is a software program, which is used to develop the cutting sequences via a PC. This program allows the user to fully test the cutting sequences in a simulation mode prior to loading on the machine. ASA requires new FACEBOSS control hard ware, which is intended to improve the overall accuracy of the automated cutting sequences. The new control hardware includes: Haulage encoders which replace the D-gear sensors, and improves machined position accuracy about face. Ranging arm proportional calves. Calve banks incorporate proportional valves to improve position accuracy Hydraulic control modules to operate proportional valves and all other hydraulically controlled valves. Two-way radios for bi-directional communications which allow for latest ASA commands to operate the machine. 智能截割包括比例控制 智能截割是一种全自动的采煤机截割程序。智能截割准许用户为长壁工作面设计全套截割方案， 其中包括机头机尾截割。可以通过电脑使用 GOLP 离线工具软件（图形离线编辑器）来设计截割 方案。在将该程序加载到机器前，用户可以在计算机上进行模拟，以全面测试该截割程序的效 果。智能截割需要新的 FACEBOSS 控制硬件，来提高整体自动截割的精确性。新的控制硬件包 括： -采用牵引编码器来代替 D 齿轮传感器，精确确定采煤机在工作面的位置。 -摇臂比例控制阀，通过比例控制阀来精确操作摇臂。 -液压控制模块，可操作比例阀和所有其他的液压控制阀门 -可实现双向通信，通过最新的智能截割命令来操作采煤机。
