门禁读卡器功能测试仪设计

摘要

本设计是基于STM32系列的单片机进行的对SXG系列门禁读卡器的功能测试。在设计的同时对STM32单片机的理论基础和外围扩展知识进行了比较全面准备。对SXG系列门禁读卡器的功能测试在硬件与软件方面进行同步设计。硬件部分主要由STM32F107VCT6微处理器、LED显示电路、JTAG下载电路、电源转换电路、韦根通信电路、以及电机控制电路等组成，系统通过LED和米字型LED显示测试结果，所以具有人性化的操作和直观的显示效果。软件方面主要包括系统进入停止模式和退出停止模式、韦根通信、控制电机、键盘测试等。本系统以C语言进行软件设计，为了便于扩展和更改，软件的设计采用模块化结构，使程序设计的逻辑关系更加简洁明了，以便更简单地实现对SXG系列门禁读卡器的功能测试。所有程序编写完成后，在keil软件中进行调试, 确定没有问题后，焊接硬件测试SXG系列门禁读卡器。

THE DESIGN OF THE ACCESS CONTROL READER

FUNCTION TESTER

ABSTRACT

Taking the SXG series of access control reader for research object ,this paper designed the function tests which based on the series of STM32 microcontrollers. The theoretical basis of the STM32 MCU and peripherals expand your knowledge in the design, while a more comprehensive preparation. SXG series access functional test of the reader hardware and software aspects of the synchronous design. The hardware part is mainly microprocessors by STM32F107VCT6, LED display circuit, JTAG download circuit, the power conversion circuit, Wiegand communication circuit, and motor control circuit and other composition, the system LED-segment LED displays the test results, so humane operation and intuitive display. The software system enters stop mode and exit the stop mode, Wiegand communications, control, motors, keyboard testing. The system software design in C language, in order to facilitate the expansion and change, the software design is modular in structure, programming logic is more concise, in order to more easily achieve the functional testing SXG series access card reader. All programs after their completion, in keil software for debugging, there is no problem, welding SXG series access card reader hardware testing.
