Problems solved by technology

[0004] There are some problems in the current operating system classroom teaching and operating system experiments, which make students unable to deeply understand the internal operating mechanism of the operating system and fail to achieve the established teaching goals
These problems include: (1) The concepts and internal mechanisms in the operating system are too abstract and specialized, and it is difficult to obtain perceptual and intuitive understanding through analogy
This leads to the lack of intuition and interest in operating system experiments.
(3) Due to the problems in the learning and understanding of the operating system related knowledge in the course of learning in class, it is difficult to carry out the experiment, and because the experiment is monotonous and boring, many times students are dealing with things in the experimental class
[0013] The key knowledge point of the operating system scheduling problem is that when there are multiple processes in the operating system at the same time, allocate processors to the processes in the ready state according to a certain strategy, so as to avoid processor utilization caused by processes competing for processors. rate decline and the chronic non-implementation of certain processes

Embodiment 1

[0062] Embodiment 1: Intelligent Teaching Aids for Operating System Experimental Teaching

[0063] The turntable 1 is a rotatable disc, used to carry and drive the rubber block 15 to rotate. Carousels represent processors in the operating system.

[0064] The support platform 2 is used to carry the stepper motor 10 and the telescopic arm 3, and can rotate horizontally.

[0065] The telescopic arm 3 can expand and contract in the radial direction, and is used to push the rubber block 15 to move in the radial direction.

[0066] The small gear 4 can rotate to drive the large gear 5 to rotate. The large gear 5 rotates to drive the turntable 1 to rotate.

[0067] The digital tubes 6 and 7 are respectively used to indicate the number of a certain type of resource in the system.

[0068] The light emitting diode 8 is used to identify whether the power supply is turned on. When the power is turned on, the LED 8 emits light.

[0069] The light emitting diode 9 is used to identif...

Embodiment 2

[0094] The embodiment of the teaching aid of the present invention for demonstrating the process queue in the ready state is as follows;

Embodiment approach

[0095] Teaching aid of the present invention implements as follows for ready queue and waiting queue:

[0096] The square station 28, the square station 29, and the square station 30 form a ready queue. At this time, the system can only have up to three processes in the ready state at the same time.

[0097] Square station 25, square station 26, square station 27 form waiting queue, and system can only have three processes to be in waiting state simultaneously at this moment.

[0098] Description of teaching aid of the present invention for resources:

[0099] The digital tube 6 represents the first type of resource, and the number displayed on the digital tube indicates the number of this type of resource. The maximum number is 9 and the minimum is 0.

[0100] The digital tube 7 represents the second type of resource, and the number displayed on the digital tube indicates the number of this type of resource. The maximum number is 9 and the minimum is 0.

[0101] The teac...

Abstract

The invention relates to a teaching aid, particularly to an intelligent teaching aid used for operation system teaching, which is used for demonstrating operation system knowledge points, such as process scheduling, process synchronization, deadlock and the like. The intelligent teaching aid mainly comprises a turntable, a telescopic arm, a square table, a digital tube, a light emitting diode and a photoelectric sensor. The intelligent teaching aid combines the advantages of an embedded system and the creativity of a traditional vivid teaching aid, so that the model also combines the advantages of user self programming and visual presentation. The teaching aid has the advantages of simple and clear structure, visual demonstration and low cost, and is suitable for being popularized in teaching.

Description

technical field [0001] The invention is a teaching aid applied to the demonstration and experiment of related contents of the operating system process. Specifically, it is a teaching aid that visualizes the concepts related to processes in the operating system, and intuitively presents the states of process scheduling, process synchronization, and deadlocks during process execution in the operating system. As a visual teaching aid, the present invention intuitively presents the scene of multi-process coordinated execution under the guidance of an algorithm. Background technique [0002] The operating system is the most basic and important system software equipped with a computer. It is not only the interface between hardware and all other software, but also any digital electronic computer must load the corresponding operating system on its hardware platform in order to form a computer system that can coordinate and operate. Only under the command and control of the operati...
