Embodiment Construction
[0027] In order to further explain the features of the present invention, please refer to the following detailed description and drawings of the present invention. The attached drawings are for reference and explanation purposes only, and are not used to limit the protection scope of the present invention.
[0028] Such as figure 2 As shown, this embodiment discloses a finite state machine control method, which includes the following steps S1 to S4:
[0029] S1. Create each state of the state machine according to the name and memory address of each state of the state machine. The state includes two parent states and a final state, and each parent state includes three child states;
[0030] S2. After the current state of the state machine is executed, the next state to be jumped to is specified by the postEvent function, where the first parameter of the postEvent function is the name of the next state to be jumped to, and the second parameter is to be passed Parameters for the next ...

The invention discloses a finite-state machine control method and a finite-state machine, and belongs to the technical field of computer application, and the method comprises the steps: creating eachstate of the state machine according to the name and memory address of each state of the state machine, wherein the state comprises two father states and a final state, and each father state comprisesthree child states; after the current state of the state machine is executed, specifying the next state to be skipped through a postEvent function, wherein the first parameter of the postEvent function is the name of the next state to be skipped, and the second parameter of the postEvent function is the parameter to be transmitted to the next state; searching a corresponding memory address from the registered state list according to the name of the next state by the father state or the StateMachine, and executing an interface function of the next state, wherein each sub-state comprises threeexecution functions, namely an onEntry function, a handleTimeout function and an onExit function. According to the method, rich state machine functions are provided by adopting a simple language, andthe portability is high.
Description
Technical field [0001] The present invention relates to the technical field of computer applications, in particular to a control method of a finite state machine and a finite state machine. Background technique [0002] The function realized by the finite state machine is very simple, that is, it realizes the mutual conversion between various states. But the actual application of the state machine may require more functions, such as passing parameters when the state is switched, and the containment relationship between the parent state and the child state. [0003] The current mature state machine is the finite state machine algorithm implemented in QT. figure 1 Shows a typical QT state machine process. It can switch between states through a signal-driven mechanism, supports state machine start, stop, and pause functions. It also supports parent states including child states, switching between child states, Switch between parent states and other functions. figure 1 In, the S1 stat...
