s61, establishing a tool input-output storage allocation management data set according to the collected tool type basic data set, tool account record data set, tool type basic data set and tool cabinet allocation data set;
s62, based on a tool in-out warehouse allocation management data set, establishing a tool priority in-out warehouse allocation control model;
and S63, inputting station and tool type information of tools required to be used during tool picking, carrying out priority delivery allocation operation, and carrying out tool picking.
8. The method for controlling tool priority delivery based on radio frequency reading technology as claimed in claim 7, wherein: the S63, the priority ex-warehouse allocation operation method comprises the following steps:
s631, retrieving a category list of tool station matching tools, and matching a tool list applicable to the current intelligent storage position;
s632, prioritizing the order of the fetched tools, wherein the order calculation steps are as follows:
the first step: according to the principle of using new tools preferentially, screening tools in the new tool warranty period, wherein the number of tools with the same specification in the new tool warranty period is N, screening target tools k, and the expiration time of each new tool warranty is T 1 ,T 2 ,T 3 ,…,T N The method comprises the steps of carrying out a first treatment on the surface of the T is the current timeIf N is not less than 1, screening out the tool with the shortest remaining warranty period as a priority delivery tool: minimum remaining warranty period T Min ＝Min{(T 1 -T),(T 2 -T),……,(T N -T)}＝(T k -T)；
If N is less than 1, screening according to minimum remaining warranty time of unit maintenance cost, and the method comprises the following steps:
setting the number of tools with the same specification outside the quality guarantee period of the new tool as N ', N '. Gtoreq.2, the number of tools as i (i=1, 2, …, N '), the number of tool components as j, j=1, 2, …, M and the maintenance and replacement cost C of the j-th component j The j-th component repair warranty expiration time of the i-th tool is T ij T is the current time, the remaining quality guarantee period limit tau of unit maintenance cost,
the calculation formula is as follows:
let it be 0;
if N' > 2, screening out tools with minimum residual warranty time per unit maintenance cost and not being 0, and taking the tools as the tools to be delivered out of the warehouse preferentially, and if tau=0, indicating that all components of the tools exceed the maintenance warranty period, preferentially selecting tools with residual warranty period not expired;
if τ k ＝τ min ＝Min{τ 1 ，τ 2 ，…，τ N' }
The numbered k tool is a priority ex-warehouse tool;
if the service time is the same, the system performs random distribution;
and a second step of: the tool cabinet and the interface information of the tool K are called, and the tool taking authority is released;
s633, clicking to get, opening a cabinet door of the tool to be got by the tool, taking out the tool to carry out radio frequency reading scanning matching confirmation, ensuring that the matching is correct, updating the state of the tool account, reporting errors when the matching is wrong, prompting the tool replacement, and carrying out the matching again, wherein the matching is correct and successful.
