A method and device for integrating measurements in a land vehicle navigation system with an increased frequency of inertial sensor data readings differ from the prior art by virtue of an increase in the frequency of rough accuracy IMU measurements and the subsequent cascade processing thereof. Furthermore, the computational complexity of the algorithms in each cascade increases while the frequency of incoming data to be processed decreases: high-frequency IMU measurements are processed using simple algorithms, the processing results are transmitted to the next cascade with a decrease in data frequency, and in the next cascade, less frequent data are processed using more complex algorithms. As a result of this solution, algorithms for combining navigational measurements can be executed on cheaper and more widely available microprocessors having a lower clock frequency and a lower capacity for representing floating point numbers. By analyzing the mathematical principles of navigation algorithms, the claimed invention makes it possible to achieve a significant increase in the frequency of IMU measurements without impacting the frequency with which a navigation solution is updated and without increasing the required computing power. In addition, the claimed invention makes it possible to reduce the frequency of a navigation solution and the power of the computing device while maintaining the frequency of IMU measurements and a set accuracy of the navigation solution.

The invention relates to the technical field of double-roller cast rolling and rolling, discloses a modulation force generation method for double-roller cast rolling and rolling, and aims to solve the problems that in the prior art, motion synchronization depends on complex control logic, errors are prone to being generated, and robustness is insufficient. The method is applied to a system comprising a roller system and a constraint, and the roller system is composed of a first roller body and a second roller body which are oppositely arranged; the overall movement of the roller system relative to the fixed reference is defined as first movement, and the relative movement between the two roller bodies is defined as second movement. The geometric inevitability coupling relation of the two types of motions is constructed by presetting a constraint structure: when any motion is actively controlled, the other motion is inevitably and passively generated under the action of constraint forcing. According to the coupling relation, synchronous deviation is eliminated from the structural level, motion synchronization can be achieved without a complex algorithm, the equipment structure is simplified, the control difficulty is reduced, the system robustness and synchronization precision are enhanced, roller body stress can be optimized, the process stability and the blank quality are improved, and the coupling relation is suitable for double-roller cast rolling and rolling scenes.

The present invention discloses a method, apparatus, and storage medium for recursively parsing and executing functions. The method includes: defining an instruction set for function parsing; identifying recursive functions and non-recursive functions in ST structured text language and outputting an interpreted instruction sequence; obtaining a function instruction sequence by parsing the interpreted instruction sequence through a parser, where the function instruction sequence includes recursive function instructions and non-recursive function instructions; executing the recursive function instructions and non-recursive function instructions in the order of the function instruction sequence; wherein, when executing the recursive function instructions, a call stack of a frame stack type data structure is established based on the data frame of the recursive function instructions; and the processing functions of the recursive function instructions are sequentially called from the recursive function instruction set based on the order of the call stack for execution until the call stack is empty. The present invention makes up for the deficiency that the structured text language of the IEC61131-3 standard does not support recursive calls, improves the flexibility of the program, and meets the usage requirements of complex algorithms.
