MES (Manufacturing Execution System) client data caching method and system under unstable network environment

Abstract

The invention provides an MES (Manufacturing Execution System) client data caching method and system under an unstable network environment. An access request of an MES client for server non-tracking information data is processed by a client data caching module; a memory data access unit of the client data caching module receives the request, and transmits the request to a memory data caching management unit for processing; the memory data caching management unit processes the request, inquires a memory data cache, returns the requested data if the memory data cache has the requested data, and transmits the request to a memory data increment query unit if the memory data cache does not have the requested data; the memory data increment query unit accesses a server and returns the received request result to the memory data caching management unit, and the memory data caching management unit adds a data increment to the memory data cache. By adopting the method and the system, the time of access of the MES client to the server non-tracking information data can be greatly reduced; and meanwhile, the method and the system can be applied to the access requirements of each level of the system client.

Description

technical field [0001] The invention relates to an interactive processing method of non-tracking data between a MES system client and a server in the field of computer MES execution manufacturing systems, and specifically relates to an MES client data caching method and system in an unstable network environment. Background technique [0002] The Manufacturing Execution System (MES, Manufacturing Execution System) is a manufacturing-oriented management information system between the enterprise planning management system and industrial control. Through data transmission, it provides relevant personnel in the workshop with the execution of production plans, material consumption, and equipment status monitoring. And quality statistics and other information are not only the basic technical means to realize the agility of workshop production, but also an effective means to communicate the information island between the upper-level plan management and the lower-level control. In th...
