Abstract: A method and device are provided for diagnosing a weighing system. In the method, the weighing system acquires an intrinsic parameter, a status parameter, and an operating parameter of various components of the weighing system, environmental parameters of the weighing system application, and communication data and interaction data among all the components. A first-level prompt is sent when the status of any of the components is abnormal, such that the system stops operating. A second-level prompt is sent when the status of each of the components is normal and the service life status of at least one of the components reaches a preset threshold. A third-level prompt is sent when the status of each of the components is normal and a system performance abnormality event is identified for the performance status of the system. A fourth-level prompt is sent when the status of each of the components is normal.

Abstract: A control method is provided for a lamp. The lamp includes a plurality of light-emitting units, and the method includes: receiving target RGB data from a client terminal; and when the target RGB data exists in a correspondence relationship between RGB data and color temperature values, determining a target color temperature value corresponding to the target RGB data based on the correspondence relationship. The correspondence relationship between the RGB data and color temperature values is used to convert color temperature data into corresponding RGB data when an original Tuya protocol does not support color temperature data transmission. The method also includes controlling the plurality of light-emitting units to display corresponding lighting effect according to the target color temperature value.

Abstract: A pitch control method and system of a symmetrical-airfoil vertical axis wind turbine collects data by an anemometer, an anemoscope and an angle sensor, outputs an optimum pitch angle based on a control law of a pitch angle and controls the pitch angle to be the optimum pitch angle through a pitch control actuator. In addition to input variables of the control law such as a wind velocity vin and a blade azimuth angle ?, constants such as a rotation radius R, a rotation velocity ? of the blade and aerodynamic coefficients c1, c2 and c3 are also related. A Reynolds number has little influence on three aerodynamic coefficients c1, c2 and c3. The pitch actuator controls the adjustment rods to realize the automatic pitch control of the blades. An expression of the control law of the pitch is concise, the calculation time is short, and a response speed is fast.

Abstract: A pipe shield of a ventilating apparatus is disposed at an outdoor side relative to a ventilating apparatus body disposed at an indoor side, and includes a pipe shield base and a rear cover. The pipe shield has an air inlet and an air outlet disposed perpendicular to each other. The pipe shield's rear cover has a left side plate, a right side plate and a rear side plate. The distance from the pipe shield base to the rear side plate of the rear cover opposite to the air inlet of the pipe shield increases in a direction towards the air outlet of the pipe shield. A baffle is disposed at the middle portion of the rear cover, and fixed within the pipe shield by a rotating shaft fixed on the left side plate and the right side plate, the rotating shaft has a spring enabling the baffle to unfold.
