Problems solved by technology

It is particularly important that the prior art controls the printing frequency by classifying the printing information and setting the printing switch, and does not link the printing frequency with the current CPU occupancy rate of the system. That is to say, the prior art The CPU occupancy rate is not used as an important basis for controlling the printing frequency, so that it is impossible to fundamentally solve the problem that the system stability is affected due to the need to process too many printing information at the same time when the system CPU occupancy rate is high

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the following examples are given and the present invention is further described in detail with reference to the accompanying drawings.

[0020] The core content of the present invention is: by obtaining the current CPU occupancy rate of the system, comparing the current CPU occupancy rate of the system with the threshold value of the CPU occupancy rate set, and controlling the printing frequency according to the comparison result, the CPU occupancy rate As an important basis for controlling the printing frequency, it realizes the effective photographing of the printing frequency, and further describes the present invention in detail.

[0021] The core content of the present invention is: by obtaining the current CPU occupancy rate of the system, comparing the current CPU occupancy rate of the system with the threshold value of the CPU occupancy rate set, and controlling the p...

Abstract

The invention discloses a print frequency control method, which comprises the following steps: A. setting the threshold value of CPU occupation rate at the print information output time; obtaining the occupation rate of present system CPU; B. judging whether the occupation rate of present system CPU exceeds the threshold value; stopping outputting the print information if yes; outputting the print information if not. The invention improves the system stability when the occupation rate of present system CPU is high, which guarantees the system stability.

Description

technical field [0001] The invention relates to a control technology of printing frequency, in particular to a method for controlling printing frequency. Background technique [0002] Printing is very important in many communication software modules. Through the printed information, we can easily locate the fault in the system; at the same time, the printed information is also very helpful for us to observe the running process of the code. However, if the printing frequency is not well controlled and there are too many information to be printed at the same time, the printing frequency will reach a high level, which will affect the stability of the system. [0003] For example, when the system business is busy, the central processing unit (CPU) has a relatively high occupancy rate. If there are too many printing information to be processed at the same time, the CPU will temporarily interrupt the processing of certain lower priority services. Processing, switch to the proces...
