摘要： Distributed artificial intelligence (AI) can be used to monitor a wellbore operation in some examples described herein. In one such example, physical equipment can be positioned at a surface of a wellsite to support a drilling operation at the wellsite. Each piece of physical equipment may include a sensor module, a processor communicatively coupled to the sensor module, and a memory. The memory can include an AI module configured to determine a condition associated with the equipment by analyzing sensor data from the sensor module using one or more machine-learning models. The memory additionally can include a warning module for causing the processor to output a warning notification based on the condition. The memory further can include a communications module for causing the processor to transmit a communication indicating the condition to a destination via a network. The communication may be different from the warning notification.

摘要： A system is provided for calibrating ADAS sensors of a motor vehicle supported on a substantially level underlying floor. The system includes a target assembly having a base for engaging the floor. The base includes a linear alignment edge. The target assembly further includes an upright support attached to and extending vertically upwardly from the base, which support carries an ADAS target panel having a target surface secured to and facing forwardly of the base. The target surface has a horizontal axis substantially parallel to the linear alignment edge. An elongate alignment element engages and extends forwardly from the linear alignment edge. The system is positioned and oriented on the floor such that the target surface faces and opposes the ADAS sensors and the alignment element aligns with a longitudinal centerline of the motor vehicle and extends perpendicularly from the linear alignment edge of the base. This orients the horizontal axis of the target surface perpendicularly to the longitudinal centerline of the vehicle.

摘要： The present disclosure discloses a deformation and control simulation test system for a tunnel engineering supporting structure, including a follow-up hoisting platform, actuators, a control system. It is horizontal structure. The follow-up hoisting platform reduces the friction caused by the weight of testing sample and facilitates experimental operations. Each actuator fixed on an annular box body reaction frame can move independently through a control system in form of force control or displacement control mode, and can achieve circumferential contraction loading through its gomphodont configuration. The hinged and curved design of the cushion blocks of actuators can adapt to the circumferential contraction deformation of a test sample and maintain a close fit with them during the loading process. The present disclosure provides a good solution for physical model tests on deformation and control of tunnel engineering supporting structures including uniform loading, non-uniform loading, and long-term loading conditions.

摘要： A computer-implemented method, system, and computer-readable medium for automatically generating a combined display of measurement data representing a combined measurement, such as a multiphase parameter, includes establishing, by a mobile computing device, communication connections with a plurality of measurement devices configured to generate measurement data. The mobile computing device receives the measurement data generated by the plurality of measurement devices, and in response to information indicative of the measurement data representing related parts of a combined measurement, the mobile computing device automatically groups the measurement data received from the measurement devices and automatically displays the grouped measurement data in a combined display that shares at least one axis of measurement. In at least one embodiment, the combined measurement is a multiphase parameter, such as a three-phase electrical parameter, and the combined display is a graph in which the measurement data shares at least one axis of measurement, such as time.
