【摘要】 随着计算机网络应用的日益普遍,许多场合对信息化管理要求的不断提高,如何设计一种支持多种身份识别方式、运行稳定的网络化闸机控制系统将很有意义。本文在综合利用了计算机技术、网络通信技术和嵌入式系统技术的基础上,对基于以太网的嵌入式闸机控制系统进行了深入研究。本文设计了以ARM7微处理器为核心、具备以太网通信能力、支持多种读卡设备的嵌入式闸机控制系统。完成了SQLite嵌入式数据库系统及相关模块设计,最后完成检测非法闯入控制策略的实现。更多还原

【Abstract】 With the more and more popular application of computer network, the requirements of information management have been enhanced, and it’ s meaningful of how to design a kind of supervisory control system of door entry based on Ethernet which can support multi-method of identifications and work steadily. Based on the using of the technology of computer, network communication and embedded system, the embedded supervisory control system of door entry is studied deeply. In the hardware design, the ARM7 MCU is its core and Ethernet communication and multi-method of identifications is realized. The embedded database named SQLite and different modules of the program is introduced in the software design. At last, the control strategy of illegal entry detection is realized.更多还原
