The application provides a high-altitude detection system of a wind speed and direction sensor, wherein the high-altitude detection system is installed on a transport operation platform, is lifted and stabilized on a wind speed and direction sensor operation plane through the platform, and is used for high-altitude real-time detection and / or calibration of the wind speed and direction sensor. The wind speed and direction sensor is usually installed at a high position, such as a wind speed and direction sensor on a catenary support post, which is installed at a position with a height of 4000 mm from a rail surface, and two wind speed and direction sensors are installed and fixed at each position; meanwhile, a railway line is relatively long, and even if real-time detection is carried out on site, it is very time-consuming and laborious. The application utilizes the extensibility of the operation platform at a high altitude and the convenience of long-distance transportation on the ground, meets the high-altitude detection needs of the wind speed and direction sensor, and unexpectedly solves the important practical problem of restricting the on-site detection of the wind speed and direction sensor.

The utility model relates to a peripheral pump impeller which comprises a wheel rim and a wheel shaft integrally formed in the center of the wheel rim, blades are arranged on the two axial end faces of the wheel rim and extend in the radial direction of the wheel rim, the outer ends of the blades are flush with the outer edge of the wheel rim, and the outer edge of the wheel rim is flush with the outer edge of the wheel rim. And the angle between each blade and the rim deflects towards the rotating direction of the impeller. Aiming at the efficiency and energy consumption problems of the peripheral pump, by changing the shapes of the blades in the impeller and deflecting the angles of the blades towards the rotating directions of the blades, a structure similar to a paddle shape is formed, so that fluid can be guided to enter a flow channel of the peripheral pump more smoothly, the speed distribution of the fluid in the flow channel of the impeller is improved, the hydraulic loss is reduced, and the efficiency is improved; and the energy consumption is reduced.

A task scheduling and data interaction system and method for large-sample simulation includes a three-layer system of "center-region nodes". The center layer is used to batch allocate tasks to the most suitable regions according to the computational characteristics of the tasks. The region layer performs fine-grained allocation based on the real-time resource status of the nodes in the node layer. The computational results generated on different nodes flow to the distributed stream processing of the center layer to complete the pre-deployed analysis job. Data interaction between different regions in the region layer is carried out using the DDS data exchange bus. The flow of computational results to the distributed stream processing of the center layer is carried out using the DDS data exchange bus or a regional data aggregator. The node layer can automatically and seamlessly switch between microsecond-level "shared memory communication" and DDS-based real-time "network communication" depending on whether the models involved in the interactive data are located on the same physical node.
