The application relates to the technical field of computer vision, and provides a high-stability virtual object position display method and device. In a mapping stage, the object structure of a virtual scene is acquired, and an exception handling boundary is established; in the exception handling boundary, a virtual object in the virtual scene is regarded as a general engine object, coordinate data corresponding to the general engine object is acquired based on the object structure, and a path graph is drawn according to the coordinate data; the running state of a data processing process in the exception handling boundary is monitored, if running exception is detected in any processing period, the exception data corresponding to the running exception is discarded; in a virtual scene running stage, the position information of the virtual object is acquired in the exception handling boundary, the position information is matched with the path graph, the relative position of the virtual object in the path graph is determined, and the relative position of the virtual object in the path graph is displayed. Runtime exceptions in memory reading or drawing processes are effectively intercepted and isolated.

The invention relates to the technical field of electronic data processing, in particular to a multi-task real-time operating system scheduling optimization method for a PPEC controller. The method comprises the following steps: constructing a physical time snapshot of interrupt response by using a hardware timer and a direct memory access unit, and collecting entry and exit moments when a rigid control task is interrupted by a non-control task; calculating time debt based on the interruption physical duration, constructing a space-time mapping model in combination with the power grid reference angular frequency, and converting the time debt into a phase lag angle of a voltage space vector; and comparing the time debt with an atomic operation time threshold value, dynamically switching to a compression mode or a fusing mode according to the time debt and the atomic operation time threshold value, and executing task scheduling according to the selected mode. According to the method, the time drift is mapped into the vector phase error of the physical layer, so that the problems of waveform distortion and control divergence caused by sudden interruption are solved, and the physical synchronization of control is ensured.
