pin18系列开发板应用说明
目前，在工业控制等应用领域中，大多数设备的通信接口都符合RS-232 通信标准。
RS-232 通信方式的数据传输半径十分有限，远远不能满足远程传输的需求，且不能与Internet 直接通信。
针对上述问题，在系统设计中，一般采用两种方法将串口设备进行有效改进后与Internet进行通信：①更新原有系统，采用能够接入Internet 的新产品，或者对原有系统的全部或局部进行重新设计。
这种方法可能从根本上解决系统连接到Internet 的问题，但是成本较高、周期较长；②在原来的设备上使用RS-232-Internet 的协议转换器，实现Internet 的接入。
本文主要讲述第二种方法，即如何利用P IC18F66J60 微控制器实现将因特网发送的数据包提取出来，通过串口送入用户设备，达到远程控制的目的。
1. 概述PIC18F66J60 微控制器实现的Ethernet- RS-232 协议转换器的Demo 板实物图如图1 所示，具有以下特征：①单芯片完成协议转换功能，大大降低系统成本和复杂程度。
②模块尺寸只有一张信用卡的一半大小，功耗不到1W，方便将其集成到系统设备中。
③ETORS232 内部集成TCP/IP 协议栈，用户无须编程TCP/IP 协议，即可将用户产品接入到以太网中。
④10MEthernet 接口，最大波特率为115200 b/s。
⑤支持动态(DHCP) 或静态获取IP地址。
⑥支持三种不同的网络连接模式：TCP SERVER 模式、TCP CLIENT 模式和UDP 模式。
⑦可以方便的使用Windows 应用程序NetConfig，进行网络参数查看和配置。
2. 硬件设计2.1 PIC18F66J60 微控制器PIC18F66J60芯片是Micro Chip公司新推出的一款以太网微控制器，具有出色的计算性能、丰富的功能集和极具竞争力的价格优势。
PIC18F66J60微控制器包含一系列串行通信外设：2 个独立的增强型US ART 和2个主控SSP 模块，能够进行SPI 和I2CTM（主控和从动）模式操作；通用I/O 端口中包含一个可重新配置为8 位并行从动端口，用于处理器之间的通信；本系列的所有器件均包含2 个捕捉/ 比较/PWM (CC P) 模块和3个增强型CCP（ECCP）模块，可方便灵活地实现控制应用，在同一时间内，微控制器最多可以使用4 种不同时基执行不同项目的操作。

第一章系统概述随着智能技术、信息技术的迅猛发展，对各类大中院校的通信自动化、办公自动化和管理现代化都提出了更高的要求。
在各类大中院校内采用非接触式门禁管理技术，将大大提高学校的综合管理和管理效率，为教师和学生提供一个安全、便捷的工作学习环境。
对学校而言，校门出入的管理是一项日常管理工作，其不仅直接关系到学校的安防问题，而且也会影响到学校的教学秩序和学习纪律。
目前，大部分学校都由门卫对人员的出入进行人为识别，然后进行登记、签证等方式处理，存在工作效率低、出错率高等问题。
学生宿舍门禁管理系统对于一个学校来说是必不可少的组成部分。
目前好多学校还停留在宿舍管理人员手工记录数据的最初阶段，手工记录对于规模小的学校来说还勉强可以接受，但对于学生信息量比较庞大，需要记录存档的数据比较多的学校来说，人工记录是相当麻烦的。
而且当查找某条记录时，由于数据量庞大，还只能靠人工去一条条的查找，这样不但麻烦还浪费了许多时间，效率也比较低。
蓝本校园门禁管理系统采用先进的智能卡门禁管理技术，它能够自动识别出入人员的身份、自动判别出入权限、自动记载出入信息。
不仅有助于学校的安防管理和人员管理，其先进性也更体现了学校管理工作的科学化与智能化，让学校校门的出入管理变成了一件轻松的事情。

目前，大多数的嵌入式系统是以MCU为核心，与一些监测、伺服、指示设备配合实现一定的功能。
在工业控制等多数领域中，大多数的设备的通信接口符合RS-232通信标准。
这种通信方式的数据传输半径十分有限，并不能满足远程传输的需求，而且不能接入Internet。
有两种方法可以将这些串口设备进行有效的改进，使其接入到Internet。
一种方法更新原有的系统，采用能够接入Internet的新产品，或者对原有系统的全部或局部进行重新设计。
这种方式可能从根本上解决系统接入到Internet问题，但是其成本较高、周期较长。
当系统的复杂程度较高或者价格较昂贵时，成本和周期的问题格外突出。
另外一种方法是在原来的设备上面使用RS-232到Internet的协议转换器，实现Internet的接入。
不论从复杂程度还是成本上面，这种方法明显优于第一种。
Microchip Technology针对嵌入式系统的Internet接入应用开发出8位集成以太网控制芯片的单片机PIC18F97J60，并发布了基于此芯片的TCP/IP协议栈。
