3、清理控制箱中的硬币,极为不方便。 而刷卡式自助洗衣机的出现解决了投币式洗衣机出现的问题,近年来得到 了快速的发展,但这种模式也需要事先购买储值卡。随着线上支付的出现 与完善,提供给了我们一种更加便捷的消费模式:线上支付模式,用户可 以通过网银支付或者是微信支付等线上的支付手段进行消费,彻底摆脱了 消费前需要准备硬币或者是储值卡的过程。为 了实现线上消费与线下服务 的对接以及对自助洗衣房洗衣机的集中管理,本文提出了一种基于嵌入式 Linux的自助洗衣房集中控制器的设计方案。 根据山西客来安洗涤机械有限公司对线上支付模式以及对现有的刷卡 消费数据管理的要求,提出了自助洗衣服务系统的总体设计方案,并
4、对实 现线上服务与线下操作对接以及对自助洗衣机集中管理的自助洗衣房集中 控制器进行了总体的设计。集中控制器以嵌入式 ARM处理器作为控制器的 核心,选用嵌入式 Linux作为控制器的软件开发平台。 控制器的硬件电路以 S3C2440的 ARM处理芯片作为主控核心,配合 I 太原理工大学硕士研宄生学位论文 控制器的功能要求设计了外围接口扩展电路。通过 CAN总线将洗衣房的多 台洗衣机接入集中控制器中,实现洗衣机与集中控制器的数据通信,同时 通过 WIFI将集中控制器与远程的服务器连接进而实现控制器与远程服务 器数据的传输以及对远程服务器操作指令的接收。集中控制器将洗衣机的 实时数据和刷卡消费数据
5、存入数据库,方便用户通过人机界面按条件进行 查询,当远程服务器需要某台洗衣机的某个时间的数据时,控制器将对应 洗衣 机的该时刻数据从数据库中提取出来后经由 WIFI发送给远程服务器。 利用 VB设计了上位机监控程序,采用 Access设计了刷卡消费用户的 消费数据的数据库,并通过 ADO的方式将 VB程序与 Access数据库进行了 连接,从而将集中控制器发送的消费卡的消费数据存入数据库中,方便对 数据的管理和查询。 最后,搭建控制器的实验平台并进行调试,通过测试验证了控制器对 洗衣机实时监控的准确性与稳定性,证明了线上与线下服务对接的可能性。 关键词:自助洗衣机,嵌入式, Linux, WI

Now, it is widely used in universities, factories and other collective apa
7、rtment to in order to meet user needs. As early as 2004 years, our country began to produce coin-operated self-service washing machines and it is obtained the rapid development in 2006. So far, self-laundry market has coin-operated washing machines and brush card self-service washing machine. In ter
8、ms of coin-operated self-service washing machine, the user need to prepare a certain amount of coins when using. At the same time, it is also need managers regularly clearing and cleaning the washing machine coins which is very inconvenient. However, the emergence of the brush card self-service wash
9、ing machine has solved the problems of the coin-operated washing machine which is obtained the rapid development in recent years. But this model also need to purchase the cards in advance. With the emergence of online payment and perfection, it is provided us a more convenient consumption patterns:
10、online payment mode. The user can through the online payment method such as e-currency payment or WeChat pay to make the consumption. Thus the III 太原理工大学硕士研宄生学位论文 consumer can thoroughly get rid of the process of preparing coin or cards in advance. In order to realize online consumption and offline
11、service, this paper proposes a centralized controller design scheme which is based on embedded Linux. According to the requirement of online payment mode which is commanded by the Shanxi guest Ann washing machinery co., LTD. This paper make the overall design of the concentration controller of washi

Centralized controller uses the embedded ARM processor as the core of the controller, choosing embedded Linux as the controller software development platform. Controller hardware circuit uses the ARM S3C2440 chip as contr

Through CAN BUS MODE to make several washing machine in laundry room to connect with the integrated controller. Thus we make the realization of the washing machine and the centralized con

Then we can implement controller to transmitting data and receiving instructions which is from the remote server. The controller saving washing machine real-time data to
