Problems solved by technology

However, when there are more than expected single products that cannot meet the grouping requirements, it is necessary to disrupt and redistribute the part of the group that has already been grouped. The work is repeated, the efficiency is low, the success rate is low, and there are also copying errors, misreading, and miscalculations. possibility of

example

[0021] There are 46 products in this batch to be grouped, each product contains 6 pieces of data that need to be grouped, and 4 products are required to be grouped, and the difference between all corresponding data of these 4 products is not greater than 30, and the serial number is 2012001~2012046.

[0022] Now determine the group base Δn=4, the required tolerance Δ=30, the actual tolerance Δ 1 =15

[0023] Select the data files containing these 46 products, see Table 1;

[0024] First take out 4 precision products numbered 2012001, 2012002, 2012003, 2012004;

[0025] Judge the data of 2012001, 2012002, 2012003, and 2012004, assuming that the result is greater than Δ 1 , does not meet the grouping requirements;

[0026] Randomly take out a precision component from the list to be grouped and randomly replace one and repeat the previous step. Assuming that the combination meets the grouping judgment requirements until 2012006 is used to replace 2012001, then write 20...

Abstract

The invention belongs to the field of precise instruments for aviation and particularly relates to a rapid grouping method for precise elements. With the adoption of the rapid grouping method for the precise elements, provided by the invention, the automation of a grouping process can be realized. Data can be processed by using a strong computing capacity of a computer, so that the work, which needs to be finished for some hours originally, can be immediately finished; a result can be automatically stored. With the adoption of the rapid grouping method for the precise elements, the precise elements failing to meet the requirements can be randomly replaced, so that the grouping work can be finished in a maximum and optimal manner; an optimal scheme can be rapidly found out through random selection and random replacement by using the strong computing capacity of the computer, so that not only can the human resources can be released, but also the grouping quality and the grouping stability can be improved. Meanwhile, the working efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the field of aviation precision instruments, in particular to a method for quickly grouping precision components. Background technique [0002] With the continuous improvement and development of aviation product technology, redundant sensor products as system information feedback have been widely used. The current redundancy sensor is to manually judge the performance of a whole batch of single sensors, divide several single sensors that meet the requirement of redundancy consistency into different combinations, and use these combinations to achieve redundancy during final assembly and performance debugging. Product Features. Whether the maximum grouping and optimal grouping can be achieved is subject to factors such as the experience, method, and work attitude of the grouping personnel, because the manual grouping process requires dozens or even hundreds of tables to be put together for corresponding data comparison Calculat...
