文档介绍：西南交通大学本科毕业设计(论文)第I页摘要本文针对我校城轨实验室沙盘控制系统中的机车控制部分进行了相关的技术探讨与研究,并分别对机车控制部分的软硬件部分进行了设计与制作测试。本设计同时着重对控制系统的通信部分进行了深入的探讨与改进,最终实现了机车的信息无线传输、组网功能与控制机车运行等相关功能。对于整体机车控制部分的制作过程中,本设计将机车分为 MCU 部分、读卡设备部分、无线传输部分等几个模块进行分析与设计。对主控芯片选取了基于 51 系列的 STC12C5A60S2 芯片。读卡部分选择了 MFRC522 射频卡读写器,而对于核心的通信模块部分本设计选取了APC22 0及WIF I 无线通信模块作为前期与后期的通信模块来进行设计与制作的硬件。之后本设计在进行实际系统硬件设计中,从整体方案、电源电路、电机驱动、射频卡读写部分以及无线模块电路部分进行了设计与制作。并着重对无线通信部分的 WIFI 模块进行了组网设计制作。同样的,在对系统进行软件设计制作中,本设计也分别对机车控制的各个模块进行了编写与制作,并对组网功能进行了实现,在最后软硬连调连试中达到了本设计的预期目标。对于整个设计而言,是较好地完成了预期的目标,但仍在 MCU 控制部分及 wif i 模块自动切换部分存在着一定的改进空间。关键词机车控制;无线传输; WIFI 模块西南交通大学本科毕业设计(论文)第II页 Abst r act In this paper,we have discussed and designed the otive-vehicle control system of Urban Mass Transit Control munication Laboratory . At the same time, we deeply focus on the control system munication , and finish the achieved otive wireless transmission of information, networking function and control the operation of otive and related functions in the end . While we making the whole otive control , we separate the system as these parts : MCU,card reading service,Wireless transmission use the STC12C5A60S2 of C51 series as MCU , MFRC-522 as card reading service , APC220 as previous transmission service and replace itby use these hardware module to design our system. We also making our otive control system by some part of the overall scheme , power circuit, motor drive part and the wireless module circuit,and pay more attention to the munication of the WIFI module working the later period we have test every part ofour otive control system , especially for working , we reached our aim in the end. As for the whole design , we have finished our aim essfully , but still have some defects and need some improvements for MCU and WIFI devices .
