摘要
为解决传统一卡通售饭方式弊端,提高餐厅售饭的自助化和智能化,提出一种基于ARM和WinCE平台的称量销售式自助售饭系统设计方法。首先,运用传感器、RFID、ARM、语音播放、无线WiFi等技术构建自助售饭机硬件系统;其次,在WINCE操作环境下,采用C++和SQL设计售饭机人机交互、数据上传和后台数据监管部分软件系统;此外,为提高整机称量性能,采用稳定识别算法对DL101传感器模/数转换数据进行稳定识别处理,采用最小二乘法对称重数据进行非线性校正。测试分析表明,系统运行稳定,称量精度高,支付便捷,操作简单,具有较好的实用性。
A design method of weighing and selling self-service rice vending system based on ARM and WinCE platform is proposed,to solve the shortcomings of the traditional way of rice vending with one card and increase the self-service and intelligent restaurant sales vending.The hardware system of self-service rice vending machine is composed of the sensors,RFID,ARM,voice playing,wireless WiFi and other technologies.In the WINCE operating environment,the software systems of human-computer interaction,data uploading and background data monitoring parts of the self-service rice vending machine is designed by means of the C++and SQL.The stable identification processing of the DL101 sensor’s analog-to-digital conversion data is performed by means of the stable identification algorithm,and the nonlinear correction of the weighting data is conducted by means of the least square method,after which the weighting performance of the whole machine is improved.The testing analyzes show that the system runs stably,and has high weighing accuracy,convenient payment and simple operation,which has a certain practicability.
