Configuration Software, The Graphic Configuration Module And Database Access Module Design And Implementation,

The traditional industrial control software has obvious shortcomings, such as weak flexibility, comparatively long development period, inconvenience to maintain, etc. In order to overcome those disadvantages, design and implementation of configuration software. This paper investigates the graphics module and Data Acquisition Module Design and Implementation.In this paper, a design model of the factory model to graphic design configuration software configuration module. Object-oriented design model is the practical application of technology. In the actual software projects, factory mode (Factory Method) is the most widely used mode of the design. Factories used to create a model definition of the target interface, an example of the type of decision of which category. Application of the factory model of the structure of the system compact concise, easier to understand. In subsequent maintenance, it is easy to find the need to be amended, reduced maintenance workload. In the need to add new features, they only function of the preparation of a new code, rather than amending spent the previous logic, a decrease of the new features bring added workload. In this paper, graphic element on the creation, preservation, modification, graphics interface, and other items flashing the basic problems encountered in a detailed description.Data Acquisition Module to collect data sent via Ethernet processing units of the real-time data, only to run in the running state. It industrial real-time data acquisition, View Add memory modules for the visit, such as real-time trend. Data Acquisition Module using shared "memory image files," namely FileMapping technology, and configuration software solution for the data-processing unit of interactive communications. Data Acquisition Module also on the data collected in accordance with the historical library, SOE, alarm processing, and other business logic.This paper introduces a buffer database access technology, and slow to resolve database access data buffer. Database buffer visit by more than one process can access the queue to achieve. The queue memory image files used to achieve, as the queue several different threads will visit at the same time, this paper is based on Windows kernel objects: Exclusive volume beacon synchronized. Need access to the database will process database requests for visits Add to queue from another database access module to carry out the actual data read operation. Application of the technology, improving speed access to the database, the system can increase the number of collection points, can reach 40,000 points collection.
