With the acceleration of transportation, accounting transported goods acquired great importance. Even in modern conditions the weight remains the most reliable indicator of accounting materials. Unlike many other variables which can be measured indirectly, by weight can be measured directly and accurately. When using strain gauge weight sensors reading can be obtained within a few milliseconds, and this reading may correspond to the instantaneous load exerted on the sensor. Determination moving vehicle weight is only possible by appropriate processing of the sensor signal. In addition to standard analog and digital filter algorithms in the literature indicated a number of methods of processing the results. Based on the nature of the noise in the stahosticheskogo article is an attempt to simulate the noise in the form of time series avtoregeresivnogo process. The results of the simulation.
