The invention provides an intelligent ring equipment state management method, system and application. The method comprises the following steps: starting a state manager; starting scanning, monitoring a scanning result through a state manager, and starting equipment adding logic and equipment connecting logic; when the device information of the intelligent ring is obtained, analyzing whether the intelligent ring is bound by the main program: if the intelligent ring is bound, terminating the device adding logic, triggering the connection service through the state manager, and completing the device connection of the intelligent ring; and when the data synchronization logic is started, the state manager completes data synchronization related to multiple data types between the intelligent ring and the main program based on a state waiting mechanism. The state waiting mechanism and the state manager are introduced, so that the state judgment logic in the intelligent ring connection process is optimized, the connection stability of the equipment and the reliability of data synchronization are improved, and the abnormal condition of data synchronization of the intelligent ring under the condition that the system is unstable is avoided.

This invention relates to the field of mobile device camera testing technology, and discloses an Android dynamic adaptive screen camera testing system, including a light sensing module, an algorithm module, a parametric template system, a distortion compensation engine, and a differential rendering module. The light sensing module collects ambient absolute illuminance data; the algorithm module calculates the ambient illuminance gradient and controls the system state flow; the parametric template system reconstructs basic texture parameters based on the gradient to generate a two-dimensional texture of the test pattern; the distortion compensation engine constructs a non-uniform three-dimensional geometric mesh model based on the screen curvature radius and performs spatial distortion calculations on the vertices of the two-dimensional texture; the differential rendering module obtains a feature mask image, performs shading resource reallocation calculations, and sends a timing synchronization trigger command to the camera under test after rendering is completed. This invention can reduce the impact of sudden changes in external ambient light on the pattern display quality and compensate for the geometric deformation at the edges of curved screens.

The invention relates to the technical field of mechanized operation vehicle road times and operation areas, and discloses a mechanized operation vehicle road times and operation area algorithm and system. By defining the mechanical operation vehicle as the working vehicle, the algorithm terms are simplified, the specifications of the discharge ports are assumed to be consistent, the calculation complexity is reduced, and the universality is improved. The space relation between the feeding face and the discharging face is determined, and a foundation is laid for calculation of the working range of the discharging port. By marking the bevel edge and the end point, a geometric model is constructed by using the intersection point of the extension line and the ground, and the vertical distance between the material edge and the ground is calculated. The effective working length of the discharge port is calculated by combining a similar triangle principle, and space mapping is completed by measuring the lengths of a plurality of key line segments to adapt to different working heights. And finally, the total effective working length of the discharge port is calculated, and data support is provided for path planning and efficiency analysis.
