Embodiment 1
[0050] refer to figure 1 , the present embodiment provides a command timeout processing method, including:
[0051] Step S101, establishing a command queue;
[0052] Step S102, receiving a command sent by the host, and adding the command to the command queue;
[0053] Step S103, recording the time when the command is queued and the preset timeout period, and estimating the time required for the execution of the command;
[0054] Step S104, detecting whether any command has been executed, and if so, recording the completion time of the command;
[0055] Step S105, updating the waiting time of each command in the command queue according to the completion time of the executed command and the queue entry time of each command in the command queue;
[0056] Step S106, updating the execution time required for each command according to the system operation;
[0057] Step S107, traversing the waiting time and execution time of each command in the command queue, and judging whether ...

Abstract
The invention provides an order overtime processing method and system. The method includes: building an order queue; receiving orders sent by a host, and adding the orders into the order queue; recording queuing moment of the orders and preset overtime duration, and estimating duration needed for executing the order; detecting whether there are orders whose execution is completed or not, and if yes, recording completion moment of the orders; according to the completion moment of the orders whose execution is already completed and the queuing moment of each order in the order queue, updating waiting duration of each order in the order queue; updating duration needed for executing each order according to system running condition; traversing the waiting duration and the duration needed for execution of each order in the order queue to judge whether order overtime occurs or not; if yes, adjusting overtime orders. By the method, the problem of overtime of the orders can be avoided effectively.
Description
technical field [0001] The present invention relates to the field of computer technology, in particular to a command timeoutprocessing method and system. Background technique [0002] In the current control system, the processing speed of the host computer is getting faster and faster, but in many cases, the running frequency of the device side cannot be consistent with that of the host computer. The device side generally uses the form of command queue to buffer commands to facilitate post-processing. However, once the command on the device side is executed, it cannot exit the service as easily as the host, and needs to wait for the command to be executed or exit after a timeout. This will cause some high-priority commands to be executed in advance, while some low-priority commands are prone to timeout. Contents of the invention [0003] The purpose of the present invention is to propose a command timeout processing method and system for the above-mentioned problem in th...
