A leveling erection control process design method based on a multilayer finite-state machine (FSM) aims to solve the technical problems that data processing instantaneity and reliability of a leveling erection control process of an embedded controller with no operating system cannot be ensured; the method comprises the following steps: dividing the leveling erection control processes so as to form a control task formed by combining corresponding control processes; dividing work states of each control process in the control task according to control steps or control grades; relating work states of corresponding control steps or control grades with corresponding task control segments; combining work states of corresponding control steps or control grades so as to form same layer state sets; combining state sets of each layer into a multilayer finite state set; using corresponding state of the control process to start the corresponding task control segment in the leveling erection process.
Description
technical field [0001] The invention relates to a software design method, in particular to an embedded software design method with high requirements for high real-time performance and parallel control. Background technique [0002] The land-based vehicle-mounted mobile launch platform provides the initial shooting angle and direction for the missile through the leveling and erecting system. As one of the control cores of the leveling and erecting process, the leveling and erecting control process generally runs on an embedded control system without an operating system. To improve real-time and reliability. [0003] However, the leveling and erecting control process running on an embedded controller without an operating system lacks perfect process control means, and the state of each component process in each control task cannot be effectively used, and the entire control process cannot be unified and coordinated, and cannot be guaranteed. Higher real-time and reliability. ...
