摘要： A transmitter for an inground operation includes an antenna and a sensor section for generating sensor data. An antenna driver selectively drives the antenna to emit a locating signal such that the locating signal carries the sensor data. A processor controls the antenna driver to transmit the locating signal during a normal mode and to enter a sleep state that disables at least the sensor section and the antenna driver such that the locating signal is not transmitted responsive to detecting that the transmitter is inactive. The processor can enter a snooze mode from the normal mode by disabling the antenna driver so that the locating signal is not transmitted, without disabling the sensor section, and the snooze mode requires less power than the normal mode but more power than the sleep state.

摘要： A planning tool plans movement of a boring tool for an underground drilling operation. The planning tool includes one or more wheels for rolling on a surface of the ground along a path responsive to movement by an operator to characterize the surface contour and to generate guidance for the boring tool to reach a target position. Planning can additionally be based on waypoints. The planning tool can be rolled unidirectionally or bidirectionally to characterize the surface contour. Bidirectional movement cancels accelerometer fixed bias. Path stitching is used to plan around obstacles. The planning tool can facilitate tracker placement. The planning tool can collect noise information for frequency selection purposes. A described technique maximizes linear drilling in an underground plan. Compensation and/or warnings are provided for unsteady, fast and slow movement of the planning tool while measuring the surface contour.

摘要： A boring tool is movable through the ground. A transmitter supported by the boring tool transmits an electromagnetic homing signal. A portable device monitors the electromagnetic homing signal and receives the electromagnetic homing signal in a homing mode for guiding the boring tool to a target position. A processor generates steering commands for guiding the boring tool based on a bore plan in a steering mode such that at least some positional error is introduced without using the electromagnetic homing signal. Switching from the steering mode to the homing mode is based on monitoring of the electromagnetic homing signal as the boring tool approaches the portable device to then guide the boring tool to the target position location in compensation for the positional error. Intermediate target positions are described as well as guiding the boring tool based on the homing signal so long as the portable device receives the signal.
摘要翻译：一个无聊的工具可以通过地面移动。由钻孔工具支撑的变送器传送电磁归位信号。便携式设备监视电磁归位信号并且以归位模式接收电磁归位信号，以将钻孔工具引导到目标位置。处理器产生用于在转向模式下基于钻孔平面引导钻孔工具的转向命令，使得在不使用电磁归位信号的情况下引入至少一些位置误差。从转向模式切换到归位模式是基于在镗刀接近便携式装置时监测电磁归位信号，然后将镗刀引导到目标位置，以补偿位置误差。描述中间目标位置，并且只要便携式设备接收到信号，就基于归位信号来引导钻孔工具。

摘要： A drilling area network hub is located proximate to a drill rig and includes an uphole transceiver in bidirectional communication with a downhole transceiver by utilizing the drill string as an electrical conductor. Certain information is collected including rig-based and/or location information. At least one field report is generated based on the certain information to characterize at least one of an inground operation, an operational condition of the downhole transceiver, an operational condition of the uphole transceiver, and an operational condition of the drill rig. A drilling area network server receives the field report from the Internet at a remote location and can generate a custom report and/or recommended actions based on field data. Region specific parameters can be applied to the operation of a drilling system. The drilling area network hub can transfer data logs to the remote location according to assigned priorities.

摘要： An inground housing is insertable in at least one joint of a drill string extending from a drill rig. The inground housing supports an electronics assembly for processing a data signal relating to the inground operation and a signal coupling arrangement for transferring the data signal between the electronics assembly and the drill rig by electromagnetically coupling the data signal between the signal coupling arrangement and the drill string such that the data signal is electrically conducted as an electrical data signal along at least a portion of the drill string that extends from the inground housing. In another feature, a current transformer is resiliently supported to isolate the current transformer from mechanical shock and vibration that is produced by an inground operation that is performed using the drill string. In another feature, a drill string repeater is described.

摘要： A housing defines a through passage along its length and is configured to support a group of electrical isolators surrounding the through passage to form an electrically isolating break in a drill string such that each isolator of the group of isolators is subject to no more than a compressive force responsive to extension and retraction of the drill string. The housing defines a housing cavity to receive an electronics package having a signal port and is configured for electrical connection of the signal port across the electrically isolating break. A housing lid can cooperate with a main housing body to define elongated slots for purposes of enhancing the emanation of a locating signal. A housing arrangement can support electrical connections from an electronics package to bridge an electrically isolating gap.

摘要： An inground isolator and associated method can provide an electrically isolated break in a drill string using electrical insulating members/isolators that are supported by a housing. During drill string operations, the isolators are subject to compressive forces responsive to both extension (pushing) and retraction (pulling) by the drill string. The isolators can be formed from an electrically insulating material such as a ceramic material. An interchangeable inground tool system is described which integrally serves to provide an electrically isolating gap in the drill string.
