Abstract

The invention discloses an intelligent two-process processing scheduling method based on a fault RGV. The method comprises the following steps: taking time length data of a single-time two-process product processed by an RGV system as system parameters; for an RGV intelligent machining system with symmetrical machining four groups of tool bits on each of two sides of the single track, selecting minimum of waiting time of idile time of a first procedure of machining bit CNC (product machining) and a second procedure of machining bit CNC (product machining) as a major target; taking into consideration the object number of machined objects, machining time and CNCcodes of machining bits for the system, establishing a biological evolution-dynamic planning prediction model so that prediction analysis is conducted on batch product production and machining; adopting a random increment learning mechanism for solving the optimal one-procedure and two-procedure distribution scheme of the machining tool bit CNC. The method provides reference to an enterprise to make a work plan.

Description

technical field

[0001] The invention relates to the technical field of RGV, in particular to a fault-based RGV intelligent two-process processing scheduling method. Background technique

[0002] With the development of automation control technology, the single-track RGV intelligent system has been widely used in various product deep processing industries instead of manual labor due to its advantages of low price, convenience and flexibility. However, due to different industry application requirements, a single-group single-track RGV intelligent system is often required to process products in two processes. The two-process processing is far more complicated than the one-process processing process. It is necessary to reasonably allocate the CNC machining tool heads, lack of a reasonable allocation plan, and the utilization efficiency of the RGV intelligent system is low. This has always been a small and medium-sized enterprise that does not have high requirements for RGV intel...
