6results about How to "Flexible and convenient control" patented technology

The invention discloses an energy storage grid-connected and off-grid switching system and a control method thereof. The invention belongs to an energy storage system control system and method, and provides an energy storage grid-connected and off-grid switching system and a control method thereof for solving the problem that when a power grid in an energy storage system breaks down and is recovered, an existing grid-connected and off-grid switching method is likely to fail in switching. According to the first type, one battery pack, one power conversion system and one static change-over switch are sequentially connected to form an energy storage cabinet, and all the energy storage cabinets are connected in parallel and then connected to a power grid and a local load. According to the other mode, a plurality of static change-over switches are connected in parallel to form a static change-over switch cabinet, a plurality of power conversion systems are connected in parallel to form a power conversion system cabinet, and the static change-over switch cabinet is connected with the power conversion system cabinet and then is connected with a power grid and a load, so that flexible wiring can be realized, and a modularized structure is arranged, so that adjustment and capacity expansion can be conveniently carried out at any time; and the stability of grid-connected and off-grid switching can also be considered.

A pressure regulating valve (11) includes a valve main body (12) having a valve chamber (13) which communicates with a refrigerant inflow passage (14) and a refrigerant outflow passage (15), a valve body (17) which changes a flow rate of a refrigerant by advancing and retreating with respect to a valve seat (16) formed in the valve chamber (13) between a valve-closed state of being seated on the valve seat (16) and a valve-opened state of being spaced apart from the valve seat (16), a pressure sensitive member (21) which biases the valve body (17) toward the valve seat (16) and which allows an advancing and retreating movement of the valve body (17) by expanding and contracting according to a pressure which the valve body (17) is applied from the refrigerant flowing into from the inflow passage (14), and an adjustment means (24) which adjusts a biasing force applied to the valve body (17) of the pressure sensitive member (21), and an actuator (a stepping motor) (40) driving the adjustment means (24) is provided. The adjustment means (24) is preferably provided with a stopper member (29) which stops the movement of the adjustment member by the actuator (40) and can be set as a starting point when setting the biasing force.

The application discloses a kind of micro-nano hard ceramic phase composite reinforced laser cladding nickel-based wear-resistant coating and its preparation method and application.The preparation method uses discharge plasma ball milling process to mix micro-nano hard ceramic and Ni-based metal powder for modification treatment, utilizes the synergistic effect of plasma activation and mechanical ball milling force of pulse discharge, effectively breaks the nano ceramic phase agglomerate, realizes the uniform dispersion distribution of nano ceramic phase in composite powder;By adopting the optimization of laser cladding process parameters, and cooperating with ultrasonic vibration auxiliary and / or pulse laser composite energy input, etc. Regulating means, prepare the nickel-based wear-resistant coating with uniform and dense structure, high hardness, excellent wear resistance and good metallurgical bonding with base material, which can meet the service requirements of mining machinery, oil drilling and production, metallurgical roller and other harsh working conditions, and has wide application prospect.

This invention relates to a six-degree-of-freedom (6DOF) measurement system and method. The 6DOF measurement system includes a camera, a prism, and a target; the optical axis of the prism is coaxial with the line of sight of the camera; the target is mounted on the target and positioned within the combined field of view of the camera and prism; the target includes a mounting base and a main shaft mounted on the mounting base, with a fixing plate on the main shaft; an annular sleeve is fixedly connected to the fixing plate, and a motor is mounted outside the annular sleeve; the main shaft of the motor passes through the annular sleeve and is connected to a transmission component, which has rollers connected to a slider. Driven by the motor, the slider can slide radially from the center to the edge of the annular sleeve via the rollers; a main marker is mounted on the top of the main shaft, and an auxiliary marker is mounted on the top of the slider. Compared with the prior art, this invention can achieve six-degree-of-freedom pose measurement of a target under uncalibrated conditions, improving the adaptability of the measurement system.

The present application relates to a kind of vehicle control method, device, vehicle and storage medium, comprising, when vehicle is in parking state, obtain user driving habit information and the video frame sequence containing face, face object detection tracking and non-face object detection are carried out to video frame sequence, obtain the face feature information and trajectory distance information of face object, the non-face feature information of non-face object;In trajectory distance information is in the preset approach distance range, and there is at least one face feature information and target face feature information matching condition, based on face feature information, user driving habit information and non-face feature information corresponding control instruction is generated to realize the automatic opening control of car door and / or trunk.No need in the case where user carries vehicle digital key, and need user manual opening control operation to the car door, trunk of vehicle, the present application can realize the automatic opening control of vehicle, greatly improve the user driving experience.
