【摘要】：洗衣机在人类如今的日常生活中扮演了不可或缺的角色,市场对于洗衣机的需求量始终十分的大,这就对洗衣机生产厂家提出了高要求:既要大量生产以满足市场需求,提高市场占有率,又要努力研发更加先进和人性化的新机型。在这个过程中,节省时间和成本是非常重要的一环,因为家庭日用品的定价始终应该在合理的范围内,这样使得自动化检测成为了洗衣机生产厂家逐渐重视起来的一个方向。本文介绍的就是一款基于LabVIEW平台开发出来的全自动洗衣机上位机测试软件,就是利用图形化编程语言开发的一款可以进行批量化自动检测并且带有一定数据分析功能的软件。首先,利用PLC实现全自动洗衣机作为下位机的所有功能,然后,要使得上位机测试软件与下位机程序之间实现通讯,并最终达到自动检测重要参数的目的。这款软件利用了同步技术,共用时钟和触发信号的办法,实现了多个采集设备的同步采集和显示;利用TCP/IP的技术,解决了多设备同时与上位机进行通讯的需要;经过简单的数据处理后,软件还可以实时地显示采集到的数据并将它们迅速存入到一个Excel文件中去。利用数据库对Excel文件可以轻松导入的原理,论文还介绍了如何用数据库软件设计一个适合存储所需数据并进行相关分析的数据库。数据库存储数据的优点是,可以按照不同的需要设计很多表单用于存储原始数据,但是,可以在不需要占用几倍资源的前提下,另外设计多个表单,用以存储形式不一样,但是源数据不改变的数据。为了操作的方便,本设计还增加了一个数据回放系统,用以配合数据采集系统的使用。这个数据回放系统是利用了LabVIEW与数据库的通讯技术,直接使用LabVIEW的界面对数据库中的文件进行操作,实现了数据再现的功能。在这个回放系统中,还增加了导出和打印的小功能,使得用户对于数据处理的各种需求都能得到很好的满足。在经过大量的理论论证和实验,这款软件也暴露出了一些不完善的地方,比如在数据处理上的一些不精确和更改设备时操作并不方便等。但是这款软件已经在生产实践中得以运用起来,希望通过以后对它不断的完善,这款软件的功能可以会越来越强大。
[Abstract]:Washing machines play an indispensable role in the daily life of human beings. The demand for washing machines is always very large in the market, which puts forward high requirements for washing machine manufacturers: to meet the needs of the market, it is necessary to produce a large quantity of washing machines.Increase market share, but also strive to develop more advanced and humanized new models.In this process, it is very important to save time and cost, because the price of household daily necessities should always be within a reasonable range, which makes automatic testing become a direction that washing machine manufacturers pay more and more attention to.This paper introduces a test software for automatic washing machine based on LabVIEW platform. It is a software which can carry out batch testing and data analysis by using graphical programming language.First, we use PLC to realize all the functions of the automatic washing machine as the lower computer. Then, the communication between the test software of the upper computer and the program of the lower computer is realized, and the purpose of automatically detecting the important parameters is finally achieved.The software uses synchronization technology, sharing clock and trigger signal, realizes synchronous acquisition and display of multiple acquisition devices, solves the need of communication between multiple devices and host computer simultaneously by using TCP/IP technology.After simple data processing, the software can display the collected data in real time and store them into a Excel file quickly.The principle that Excel files can be easily imported from database is introduced in this paper. The paper also introduces how to design a database which is suitable for storing needed data and analyzing related data with database software.The advantage of database storage data is that many forms can be designed to store raw data according to different needs, but you can also design multiple forms to store data in different forms without requiring a few times more resources.But the source data does not change the data.In order to operate conveniently, this design also adds a data playback system to cooperate with the use of data acquisition system.This data playback system uses the communication technology between LabVIEW and database, and directly uses the interface of LabVIEW to operate the files in the database, and realizes the function of data reproduction.In this playback system, the functions of exporting and printing are added, so that the user's requirements for data processing can be well met.After a lot of theoretical argumentation and experiments, the software also exposed some imperfections, such as some inaccuracy in data processing and inconvenient operation when changing the equipment.But the software has been used in production practice, hoping to improve it in the future, the function of the software will become more and more powerful.
