【摘要】：随着我国城市轨道交通自动售检票(Automatic Fare Collection,AFC)系统的蓬勃发展,对相关技术的需求量很大,硬币处理装置是自动售票机(Ticket Vending Machine,TVM)中一个必不可少的模块,它可以实现硬币的接收和找零。针对上述现象,本文以实现进口硬币处理装置的国产化为背景展开研究,设计并开发出了一套硬币处理装置的控制系统。该系统可以完成多币种接收、多币种找零、原币退还和回收等基本功能,其性能指标为真币接收率在96%以上、假币拒收率在98%以上、平均收币2枚/秒、平均找零4枚/秒。根据功能和性能指标的需求,本文介绍了硬币处理装置控制系统总体方案设计,包括硬币识别器的选型,装置整体控制系统框图和整体处理流程的设计;选择嵌入式微控制器STM32F103ZE作为装置的主控芯片,进行了硬币处理装置总控板、硬币存储模块、硬币运送模块电路的设计和电路板的制作;介绍了硬币处理装置基本业务流程设计、控制系统主要功能实现、通讯协议设计和命令/响应详细设计以及硬币处理装置硬件电路、基本命令、性能指标和异常情况下的调试与测试。通过最终的测试结果分析,本文最终开发出能够实现硬币处理装置基本功能和性能指标的控制系统。
[Abstract]:With the rapid development of automatic Fare collection system of urban rail transit in China, there is a great demand for related technology. The coin processing device is an indispensable module in ticket vending machine.It can receive coins and change them.In view of the above phenomenon, this paper studies the localization of the imported coin processing device, and designs and develops a control system of the coin processing device.The system can complete the basic functions of multi-currency receiving, multi-currency change, return and recovery of original currency, etc. Its performance index is that the receiving rate of real currency is over 96%, the rejection rate of counterfeit currency is above 98%, the average receiving rate is 2 / s, and the average value is 0 4 / s.According to the demand of function and performance index, this paper introduces the overall scheme design of the control system of coin processing device, including the selection of coin recognizer, the block diagram of the whole device control system and the design of the whole processing flow.The embedded microcontroller STM32F103ZE is selected as the main control chip of the device, and the design of the main control board, the coin storage module, the coin delivery module circuit and the circuit board of the coin processing device are carried out, and the basic business flow design of the coin processing device is introduced.The main functions of the control system, communication protocol design and command / response detailed design, as well as coin processing device hardware circuit, basic commands, performance indicators and abnormal conditions of debugging and testing.Through the analysis of the final test results, this paper develops a control system which can realize the basic function and performance index of the coin processing device.
