LIVESTOCK AND POULTRY BREEDING INTELLIGENT WEIGHING METHOD AND SYSTEM

摘要

A livestock and poultry breeding intelligent weighing method and system. The method comprises: S1, carry out measurement to obtain a weight data array an of livestock and poultry; S2, calculating whether an is less than 50% of an empirical value, and if so, taking an as a weighing system error b; S3, calculating a difference value between an-b and the empirical value; S4, determining whether the quantity of data is within a set value range, if so, executing S5, and otherwise, executing S7; S5, performing standardization processing on data of the weight data array; S6, if the difference value in S3 is within a confidence interval, storing the weight data into a weight record array if so, and otherwise, taking an which is smaller than a lower limit value of the confidence interval as a new system error value; S7, determining whether the difference value in S3 is within a set error range of the empirical value, if so, storing the weight data into the weight record array, and otherwise, taking an which is smaller than the empirical value as a new system error value; and S8, outputting a data mean value in the weight record array within a set time period as the measured weight. The method can automatically generate and adjust an empirical value and a confidence interval according to site conditions.
