For Middle And Small Home Appliances Research And Application Of Measurement And Control Platform

With the development of modern science and technology, human beings constantly create all kinds of intelligent measurement and control system.Home appliance testing process to make use of the computer monitoring and control is widely used in modern society, and also plays a very important role in the safety and economy of industrial production running at the same time.In the domestic home appliance testing equipment, widely used single device equipped with the corresponding software system, thus increases the design personnel’s workload、the equipment development cycle and the work difficulty. For this series of problems, this research is mainly to the software system platform do generalization, extensible and can be embedded in, the convenient user use, and reduce the development cycle and increase equipment more functional.The system platform is mainly divided into upper/lower machine parts. First, barcode reader will judge the product model, and send the information to the host computer (PC), Call the product corresponding to the automatic operation program with the corresponding testing standards, PLC lower detection is responsible for collecting data, using wireless communication sent to the host computer, the host computer data processing, the product test data. Analyse and judge the percent of pass of products, and finally to save the product testing parameters in the database.The focus of this study is the communication, sharing, and data processing system. Aiming at the detection requirements for small and medium-sized household appliances industry, establishing a strong applicability, high efficiency, safety and reliable test platform.The main content of the research are as follows;1. Put forward the demand for home appliance testing, user requirements, in the process of detection, the connection between the components, to build a platform for small and medium-sized electrical appliances testing system.Including implant testing standards, product automated embedded operating procedures, etc. This platform has the function of extensibility can be continuously applied to all kinds of product testing.2. Establish a system of detection mode, can quickly and effectively to identify the product classification, detection standard analysis, discriminant classification to the final product.The personal computer connected to the PLC network can provide such as process flow diagram shows, dynamic picture display, report preparation, data storage, data window technology and production management and other functions, realize to monitor one or more PLC.3. The design of communication studies, this research for PLC and barcode, PLC and smart electricity meters. PLC and various devices with their specific communication protocol for serial communication.4. This platform of PC’s research, the main program framework established using MFC of VC. The original database created with Microsoft Access for the transfer of data storage and program of field device parameters. Completion of the execution of serial control, including start-stop operation of the read and write parameters, dynamic curve. Data query interface and adds a new record interface control variable associated with a corresponding field in the database, and realization of PLC control parameters, data transmission and storage of the equipment.The monitoring system of research, based on the context of the specific project, a comprehensive, efficient design, development and management of PLC bit machine monitoring system method. Compared to the previous software system, this system platform have updated the test automation management thinking, to increase the program can be embedded in it, versatility and so on, improved the security of the data information transmitted and accuracy.
