The Design Of High Precision Computer Timer For Measurement And Control Simulation

High precision computer timer for measurement and control simulation is a kind of high precision timer based on computer platform design,provides a high precision of timing without any increase in hardware.While combining with the related knowledge of higher mathematics and mathematical statistics and ultimately concluded that under different conditions of permissible error,system corresponding accuracy,it has practical application significance,that would be applied in many areas in the future,such as industrial manufacturing,military equipment,and aerospace measurement and control,etc.In this paper,through consulting a collection of literature and analyzing the technology applied in similar systems home and abroad,and combining the relevant application scenario,this paper proposes a timer design scheme of pay attention to practical and feasible.Developing the system through the using of C#programming language,with Microsoft Visual Studio 2010 as development platform,combined with the related knowledge of mathematical statistics,the timer system initialization,timing functions,as well as the timing function demonstration,this paper focuses on using the hardware clock cycle counting function provided by the operating system,to design solutions,and with a graphical interface to display.In addition,the statistical system can run the length and the counting,recording system initial paraphrase,and through multiple sampling,calculate the other process function is introduced into system error in the process of the value of the air circulation through the step-by-step method obtained delay times N value,through the acquisition of timing point of difference,minus the before calculation system error,ultimately determine the run time interval,in the microsecond range of error control,and it is concluded that different error range,the accuracy of system output.After testing,it was proved to be feasible and reliable.At the same time,high precision timing,can be reference for the application that used in many industrial and actual measurement and control field,so that it can achieve the requirements of high-precision.
