Embodiment 1

[0024] A method for controlling the stability of a movement applied to a four-stage drive, which specifically includes the following steps:

[0025] S1. Use dynamic multi-mode clock mechanism to improve Linux clock accuracy, realize interrupt data processing and statistics for the four-level drive movement, 1Linux clock mechanism and improvement 1.1Linux clock mechanism, through the determination of clock and timer models , It is helpful to reduce the error of Linux system, the kernel should manage the running time of the system and wall time;

[0026] S2. A large number of tasks in the kernel are based on four-level driving and time driving. Some of these tasks are executed periodically, adjusting the balance of the run queue in the scheduler or refreshing the screen, and some tasks require I / O operations to be executed later. You need to wait for a relative time before running. The system clock is a combination of timer hardware and system software. In the architecture, the most ...

Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is:

[0032] The processing of jiffies specifically includes the following steps:

[0033] M1. Interrupt Chuli in standard mode. First, determine whether there is a real-time timer in the real-time timer queue. When the number of real-time timers is set, the working mode of the movement is determined, execute the function to maintain system related events, and query whether there is a real-time timer in the real-time timer queue. An interrupt processing first determines whether the jiffies clock expires;

[0034] M2. Query the linked list of real-time timers, and set the time of the next interruption generated by the movement according to the difference between its earliest time-out real-time timer and the current event;

[0035] M3. Detection in high-frequency cycle mode, specifically including interrupt processing in high-frequency cycle mode to determine in advance whether the jiffies clock expires, and if it does not e...

Abstract

The invention relates to the technical field of clocks. The invention discloses a movement stability control method applied to four-stage driving. The method comprises: using a multi-mode clock mechanism to improve the clock precision of Linux and carrying out interrupt data processing and statistics on the four-stage-driven movement. A 1Linux clock mechanism and an improved 1.1 Linux clock mechanism are realized for a four-stage-driven movement, Linux system errors are reduced by determining the types of clocks and timers, and a kernel needs to manage the running time of a system and the timeon a wall. According to the invention, the clock error can be rapidly adjusted in time, and the accuracy of clockl time is improved.

Description

Technical field [0001] The present invention relates to the technical field of clocks, in particular to a method for controlling the stability of a movement applied to four-level driving. Background technique [0002] Clock is a kind of timer commonly used in life, and people use it to record time. So far, the four generations of timepieces that have been recorded in Chinese history are: sundial, hourglass, mechanical clock, and quartz clock; [0003] The accuracy of clocks on the existing market has large errors, and the movement cannot perform self-inquiry and processing of clock errors, resulting in serious clock skew. Summary of the invention [0004] The present invention proposes a core stability control method applied to four-stage drive, so as to solve the defect of large accuracy in the prior art. [0005] The present invention proposes a movement stability control method applied to four-stage drive, which specifically includes the following steps: [0006] S1. Use dynamic m...
