The invention discloses a wind power plant yaw control optimization method based on a sequential optimization algorithm, and the method comprises the steps: obtaining the coordinates of all fans at a current inflow wind direction angle, queuing all fans after the coordinates are converted in sequence, and calculating the yaw angle range of each cycle according to the actual demands; (n-1) times of outer layer circulation are set for the first (n-1) fans in the preliminary optimization process, in each outer layer circulation, yaw angle traversal value taking circulation is conducted on a certain fan according to the obtained yaw range and the uniform step length, and then the optimal yaw combination and the corresponding power of the wind power plant are obtained; and then optimization is carried out to obtain the optimal yaw angle of each fan in the whole field. According to the method, the wake flow secondary deflection effect in the wind power plant and the influence effect of the inflow turbulence intensity on the wake flow are considered, the improved Gaussian wake flow model is adopted to comprehensively consider calculation of wake flow loss in the three-dimensional direction, the calculation result is more accurate, and the final control optimization effect can also conform to the actual engineering situation.

The invention belongs to the technical field of engine control, and particularly relates to a force application switch-on control method and device for avoiding takeoff, running and yawing, and the method comprises the steps: S1, under the conditions of initialization, parking and power-off and power-on of a controller, setting a force application automatic throttling signal to be invalid, and entering a control logic when a wheel load signal is the ground; s2, under the control logic, when the stress application connection condition is met, the stress application automatic throttling signal of the aero-engine is set to be invalid; when the force application automatic throttling signal of the other aero-engine received by the hard wire between the two aero-engines is invalid, the force application of the aero-engine is switched on, and the force application automatic throttling signal is set to be valid, otherwise, the force application is forbidden to be switched on; and S3, when the engine is connected for force application, the control logic is quitted. The safety accident that the aircraft rushes out of the runway due to the thrust difference of the two engines is avoided, and takeoff safety is guaranteed.

The embodiment of the invention provides a navigation method and device, electronic equipment, a storage medium and a computer program product, which are at least applied to the field of maps or traffic, and the method comprises the following steps: displaying a navigation map and a virtual vehicle correspondingly moving along with the driving of a target vehicle in the navigation map in a navigation interface; a navigation path of the virtual vehicle is displayed in the navigation map; under the condition that the virtual vehicle is displayed in a steering area of the navigation map and a maneuvering point located in the steering area has a similar intersection, displaying a similar intersection warning mark at the similar intersection; the steering area comprises a driving interval of a preset distance in front of the maneuvering point in the navigation path; the close intersection warning mark is used for prompting and prohibiting the target vehicle from driving to the close intersection. According to the method, warning rendering is carried out on the close intersections in the navigation path, so that a user is effectively reminded, and the phenomenon that a driver walks at a wrong intersection to cause yawing is avoided.

The present invention proposes a control system and method for adjusting pitch propulsion balance, comprising a ship propulsion device, a speed regulating module and a pitch regulating module, wherein the ship propulsion device comprises a train clock, a propulsion center control box, a diesel engine and an adjustable pitch propeller, and the propulsion center control box is respectively connected to the train clock, the diesel engine and the adjustable pitch propeller by signal; the train clock has two control modes: collaborative control and independent control; the ship propulsion device is arranged in pairs to form a left propulsion device and a right propulsion device, and the two are connected by signal transmission to realize the linkage operation of the train clock and the collaborative control of the double-engine and double-propeller propulsion system, so that the speed and pitch are automatically synchronized, the ship load is automatically balanced, and the ship yaw is avoided; the present invention realizes load balancing of the left and right diesel engines and pitch balancing of the left and right adjustable pitch propellers by synchronously connecting the left and right propulsion devices to the speed regulating module and the pitch regulating module respectively in the collaborative control mode, so as to avoid frequent operation, prevent the ship from deviating from the given route and frequently steering.

The disclosed embodiment discloses a voice navigation method, electronic device and computer program product, the method comprising: obtaining a navigation route and voice navigation content; the voice navigation content comprises voice content and voice broadcasting timing; during the driving process of the navigated object based on the navigation route, the voice content is broadcasted based on the voice broadcasting timing; after the voice content is broadcasted, the voice content of the next voice broadcasting timing is dynamically adjusted based on the behavioral feedback information of the navigated object. This technical solution can avoid the problem that the user may easily deviate when the user is not paying attention while driving by using the existing fixed voice broadcasting timing and fixed voice content, and can reduce the user's yaw rate and improve the user's navigation experience.

This application discloses a navigation method, apparatus, and computer program product, relating to the field of map rendering technology. The specific implementation scheme is as follows: during the navigation of a navigable object based on a map navigation mode, it is determined whether the navigable object has entered a pre-specified target road area; in response to the navigable object entering the target road area, navigation guidance information for the target road area is generated; the registration relationship between the real-scene image of the target road area and the corresponding map of the target road area is determined; based on the registration relationship, the navigation guidance information is superimposed on the real-scene image, and the real-scene image with the superimposed navigation guidance information is displayed in at least a portion of the navigation interface. In this scheme, by providing real-scene navigation for complex road sections and ensuring that the navigation guidance information can be superimposed on the accurate position in the real-scene image, the accuracy of real-scene navigation is guaranteed, helping to avoid deviation problems and effectively improving the user experience.
