    • A two-way communication system for transmitting command signals to and receiving operating data from a winning machine utilized in underground mining operations. The system includes a send-receive facility positioned remote from the winning machine for transmitting command information to the winning machine. A receiving means is positioned at the winning machine for receiving signals sent by the send-receive facility, and a transmitting means is positioned at the winning machine for transmitting signals corresponding to operating data of the winning machine. The send-receive facility receives the information transmitted by the transmitting means, and a separable memory is separably attached to the send-receive facility for storing such operating data and the command information. Because the memory is separable, the memory may be removed to allow the data contained therein to be analyzed at a remote location.
    • 一种双向通信系统,用于向地下采矿作业中使用的获胜机器发送命令信号并接收操作数据。 该系统包括远离获胜机器的发送接收设备,用于将命令信息发送到获胜机器。 接收装置位于获胜机器处,用于接收由发送接收设备发送的信号,并且发送装置位于获胜机器处,用于发送与获胜机器的操作数据相对应的信号。 发送接收设备接收由发送装置发送的信息,并且可分离存储器可分离地附接到用于存储这种操作数据和命令信息的发送接收设施。 因为存储器是可分离的,所以可以移除存储器以允许其中包含的数据在远程位置被分析。
