Problems solved by technology

[0011] 1) Some complex display devices are required to obtain and indicate CPU load information and system status information, which is inconvenient to operate and use;
[0012] 2) If the system is abnormal or faulty, or the communication interface cannot communicate normally, or there is no suitable external display device, the user will not be able to obtain the operating status of the system, which is not conducive to the user's positioning and resolution of system faults;
[0013] 3) Since the calculation of the CPU load is based on statistical principles, the results are all the CPU load of the last statistical cycle, and the real-time performance is not strong
[0016] The shortcoming of this prior art 2 is: because the LED indicator light usually only uses periodical lighting and extinguishing or always on and off to indicate whether the system is running normally, the user can only use it to know whether the system breaks down, and cannot Use it to obtain CPU operating load information

Embodiment

[0094]The blinking frequency of the LED is calculated by directly acquiring the CPU load statistical value calculated by the system by the CPU load state information acquisition device, without registering a task switching hook processing program. In order to make the blinking frequency of the LED reflect the CPU load in real time, the statistical period for calculating the CPU load needs to be set shorter, for example, it can be set to 1 second; the CPU load calculated by the system is usually expressed as a percentage, ranging from 0 to 100;

[0095] First divide the range of CPU load into several sections, each section corresponds to an LED blinking frequency, so that the LED blinking frequency can indicate the load status of the CPU, if the CPU load is divided into 6 sections, the minimum LED blinking frequency is set to 1 time per second , the maximum flickering frequency is set to 20 times per second, you can make a corresponding table of CPU load and flickering frequenc...

Abstract

The present invention relates to a device for real-time indicating running state of computer system in the field of computer technology and its method. Said invention utilizes the scintillation state of indication device to promptly indicate running state of computer system and running load of CPU, so that it can provide beneficial help for effectively locating system fault.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a device and method for indicating the running state of a computer system in real time. Background technique [0002] During the operation of a computer system, it is usually necessary to know the load status of the central processing unit (CPU) to grasp the operating status of the computer system. By viewing and recording the CPU load status, one can know whether the system is busy, idle, or abnormal. It is used to improve and optimize computer system software and hardware design, and locate system problems. [0003] In a physical sense, after the computer system is powered on, the CPU is in the running state as long as it is running instructions, and it is in the idle state when there are no running instructions. But in the actual application system, it is necessary to distinguish whether the CPU is performing the task we require or waiting for the task. If the CPU is perfor...
