智能像卡联网门禁系统信息采集研究

智能像卡联网门禁系统为多门集中管理（如宾馆、办公楼等）提供了一种新型的工作模式,实现这一工作模式的首要任务是进行像卡信息的采集.该文提出一种基于PC机线程像卡测量空间自传送的方法.像卡测量空间由单片机系统控制红外对管阵列而获得,经RS232总线送往联网系统上位机即PC机,PC机采用串口线程工作方式实现实时接收,在主线程中对测量空间进行整定、规范等前置处理工作.此过程的高质量完成,不但为智能像卡联网门禁系统这一新型多门集中管理工作模式的成功实现打下坚实基础,而且为以智能像卡作信息载体的新型模式输入设备的研发提供了可行性依据.

Research of Sampling of IIC Card Based on Network Entrance System

The network entrance system of IIC card provide a new working pattern for multi-door centralized management (such as hotel, block of offices, etc.), and the sampling of IIC card is the most important task. The paper describes a method of measure space is auto-send to PC based on multi-thread. The measure space of IIC card is acquired from the array infrared pair-tubes, and then it is sent to PC by the RS232 bus. The serial thread in PC can receive the information from chip-controller in real-time, and the main thread can adjust and standardize the measure space. This work completed in high-quality not only builds a solid foundation for the network entrance system of IIC card, but also provides a feasible basis for the research of a new pattern-input device based on IIC card.
