Design And Implementation Of A Fully Automatic Washing Machine Computer Software Based On LabVIEW

Today, washing machine plays an important role in human’s daily life. Because of the continuously big demand for washing machine in the market, the washing machine manufacturers are put forward higher requirements: Firstly, they need to increase the production to meet the demand and improve the market share. Secondly, they have to take more efforts to develop the new machines. Therefore, saving time and cost is very important. And the pricing should always be in a reasonable range. It leads the manufactures to pay attention to realize the automatic detection. The testing software of automatic washing machine in this paper is based on a LabVIEW platform. A method of graphical programming language is used here to develop the software, which can carry out mass automatic detection with certain data analysis function. First of all, complete all the functions of a full automatic washing machine, which is so-called a slave. Then, build up the communication between upper computer software and lower computer program. Finally, achieve the objective of automatically detection.This software uses the synchronization technology, common clock and the way to trigger signal, to realize the synchronous acquisition and display with multiple acquisition equipment. Using TCP/IP technology, it is also solved to achieve the simultaneous communication between multiple devices and the host computer. Through a simple data processing, the software can display the real-time collected data and quickly store them into an excel file. The excel files can be easily imported into the database. This is the reason why the way of designing a suitable database for storing the data. There are many advantages to store data with database: This method can meet different needs of different users. The database realizes the storages of different forms of data without storing the same data many times. It avoids wasting of the CPU space. In order to facilitate the operation, a data playback system is designed as an assistant of acquisition system. The data playback system is programmed with the combination of LabVIEW and database technology. It directly uses the LabVIEW interface to operate the database file. In this system, the simple functions of deriving and printing are also added, so that the user demand for data processing can be met very well.After lots of experiments, the software also exposed some shortages, such as the imprecision of data analyzing and the inconvenience of changing the acquisition devices. But the software has been used up in the producing. We hope that the software can be more practice with continuous improvements.
