“…A pressure sensor is an apparatus that has the capability to sense pressure signals and convert them into electrical signals that can be utilized following certain rules. Pressure sensors are commonly composed of pressure-sensitive elements and signal processing units, and are extensively employed [24]- [26]. Based on the type of pressure being tested, pressure sensors can be categorized into gauge pressure sensors, differential pressure sensors and absolute pressure sensors.…”

The high-pressure rotary jet pile construction method has been widely used in airport projects, particularly in regions with soft soil foundations, such as coastal areas. The method's primary aim is to establish a sound foundation bearing capacity. However, the conventional machinery used in constructing high-pressure rotary jet piles lacks automation. To achieve real-time quality control in high-pressure rotary jet pile construction, the development of high-pressure rotary jet pile construction data acquisition and monitoring equipment is made possible by integrating key technologies such as the global navigation satellite system (GNSS), the Internet of Things and massive data processing. The acquisition and storage of crucial construction parameters, such as the drilling position, drill rod verticality, drilled hole depth, grouting pressure, grouting lifting speed and grouting volume for high-pressure rotary jet piles is successfully implemented in this paper. A large amount of actual construction data is collected through an on-site application, and the construction quality of the high-pressure rotary jet pile machine is monitored and analyzed using geographic information system (GIS) technology. Actual applications demonstrate that the proposed digital monitoring model and method for rotary jet pile construction quality control is viable, improves the on-site management level and efficiency and has significant future value.INDEX TERMS High-pressure rotary jet pile, digital monitoring, Internet of Things, global navigation satellite system (GNSS), geographic information system (GIS).

Inspired by the exceptional flight ability of birds and insects, a bio-inspired neural adaptive flight control structure of a small unmanned aerial vehicle was presented. Eight pressure sensors were elaborately installed in the leading-edge area of the forward wing. A back propagation neural network was trained to predict the aerodynamic moment based on pressure measurements. The network model was trained, validated, and tested. An adaptive controller was designed based on a radial basis function neural network. The new adaptive laws guaranteed the boundedness of the adaptive parameters. The closed-loop stability was analyzed via Lyapunov theory. The simulation results demonstrated the robustness of the bio-inspired flight control system when subjected to measurement noise, parametric uncertainties, and external disturbance.

The growing use of drones today necessitates improved UAVs performance and capabilities. These requirements include flights in operational environments full of obstacles which present navigation and stability problems due to large-scale turbulence. To address this major concern, turbulence alleviation capabilities of natural counterparts have been studied in depth. Birds use inherent active and passive flow mechanism in their flapping wings and also deflection of covert feathers to stabilize themselves in turbulent airflows. This paper presents a novel bio-inspired gust mitigation system (GMS) for flapping wing UAVs mimicking covert feathers of birds. GMS senses the forces experienced from turbulent airflows and actuates to perform local airflow manipulations to alleviate them. GMS comprises of electromechanical feathers capable of deflecting out of the airfoil once they encounter turbulence. Modeling of single electromechanical feather assists in development of a complete GMS model that is further integrated in wing, modeled as flexible Euler-Bernoulli beam, and a complete dynamic model of flapping wing is obtained using bond graph modeling approach. We perform digital simulations and compute statespace equations to analyze model internal dynamics and responses. Comparison of the simulation results of wing without GMS and GMS-integrated wing, in response to vertical gust, confirms the efficacy of offered design. Furthermore, a good agreement between the present simulation results and experimental results from the literature validates the proposed model. As a result, the offered design successfully marks an initial step toward research into bio-inspired active gust mitigation systems for flapping wing UAVs.
