The Design And Implementation Of Incoming Inspection Information System For Power Meter Components

Currently,the manual inspection method is generally adopted during the process of incoming material inspection in power meter manufacturing.The problems including heavy workload,low efficiency and poor traceability exist in the process of manual checking,which is contrary to the concept of management with high manufacturing efficiency.The informatization management on incoming materials inspection has attracted the attention of most power meter enterprises.Building the information sharing platform and collecting the information based on the manufacturing platform during the process of incoming material inspection have become a primary means to promote the productivity and improve the product quality,thus decreasing the product cost and energy consumption.This subject originates from the practical project of Holley Technology Co.Ltd.,targeting at the practical needs in developing the information management system.The design requirement for incoming inspection information system was analyzed and the system development was realized through uniting the specific workflow of incoming inspection.The article mainly illustrates the incoming inspection process of manufacturing platform and the main contents are abstracted as follows:1)The practical needs in incoming inspection of the company was clearly known based on the investigation on Holley Technology.The designed system can meet the basic data requirements on the incoming inspection process proposed by the workshop,and have strong application reliability in the coming future.The SQL Server 2008 database was selected as database server,considering the huge data request and interaction during the incoming inspection process of each batch.2)The MVVM 3-tier architecture design mode was selected to make the best of the interlayer relationships among presentation tier,business tier and data tier and to separate business logic and page presentation,after serious consideration has been taken into the later software stability and function promotion.And this not only fits the principle of lower-coupling and higher-cohesion during software design and development,but also has the flexibility for functional expansion to meet the changes in functional requirements of the company in the secondary development of this system.3)Object-oriented method was used to build up object model to improve the reusability and scalability of the software due to the fact that the inheritance,encapsulation and polymorphism feature of this method can make the system more flexible and much easier to extend.4)Considering data analysis and judgment function of the software,the process capability analysis method and the variance analysis method are used to process the measurement data,so as to realize the effective analysis of the measurement data and improve the product quality.In this paper,the design mode was proposed for the incoming inspection information system in power meter field.Three main functional modules(information management,incoming inspection monitoring and data collection)were built and the relevant operation staff responsible for the incoming inspection management can manage the inspection for each batch with the aid of this system.The function of the system includes inspection sheet application,inspection items configuration,personnel and authority management,data query and statistical analysis and etc,which helps to cover the whole process of incoming material inspection.
