摘要
为了扩大收银秤系统的功能及提高性价比,设计并实现一种新的收银秤系统.提出以ARM LPC1766为主控制器,实现收银秤系统中称量转换、数据管理及热敏打印功能的新方案.阐述了收银秤系统相关功能模块的设计方案,给出部分模块具体电路图及产品功能程序框图.为提高称重精度及稳定性,引入滑窗均值滤波及智能动态滤波算法.测试结果表明,在保证低成本的前提下,设计的收银秤系统满足设计功能需求.
In order to extend the function and improve the cost performance of cash register scale,a new cash register scale system is designed and implemented in the paper.The new project of weighing converter,weighing systems management unit and thermal printing function controlled by ARM LPC1766 is proposed.The design scheme of cash register scale system is describe in detail.Some specific circuit modules and program block diagram are given.The software filter using moving average filter and intelligent dynamic filter algorithm are adopted to improve the precision and stability.The test result shows that the cash register scale system achieves the design requirements with low-cost.
