摘要： A transmitter is carried proximate to an inground tool for sensing a plurality of operational parameters relating to the inground tool. The transmitter customizes a data signal to characterize one or more of the operational parameters for transmission from the inground tool based on the operational status of the inground tool. A receiver receives the data signal and recovers the operational parameters. Advanced data protocols are described. Pitch averaging and enhancement of dynamic pitch range for accelerometer readings are described based on monitoring mechanical shock and vibration of the inground tool.

摘要： A drill string communication system is described. An uphole transceiver can couple a signal onto the drill string at a power that can be greater and in some embodiments is always greater than a selectable power for a downhole signal. Communication from a drill rig to an inground tool can be re-initiated using a maximum uphole transmit power of an uphole transceiver. A procedure can establish a new set of transmission parameters for a drill string signal to establish communication between the drill rig and the inground tool. The system can include a walkover locator that receives an active/inactive status-controlled electromagnetic locating signal. Responsive to a locating signal degradation, a reconfiguration command can modify the locating signal. The uphole and downhole transceivers can automatically modify a parameter of a downhole signal. An uphole receiver can apply a compensation to compensate for a drill string channel transfer function.
摘要翻译：描述钻柱通信系统。井下收发器可以以更大的功率将信号耦合到钻柱上，并且在一些实施例中总是大于用于井下信号的可选择的功率。可以使用井下收发器的最大井上发射功率重新启动从钻机到地下工具的通信。一个程序可以为钻柱信号建立一组新的传动参数，以建立钻机和地下工具之间的通讯。该系统可以包括步态定位器，其接收主动/非活动状态控制的电磁定位信号。响应于定位信号劣化，重新配置命令可以修改定位信号。井下和井下收发器可以自动修改井下信号的参数。钻孔接收器可以应用补偿来补偿钻柱通道传递功能。
