综上所述,现有技术中智能操作系统的程序架构开发方法存在当连接一些定制设备,例如RFID设备和其它特定传感器数据采集设备等时,需要每次都更新底层内核,操作比较繁琐,无法做到兼容各种底层设备,而且不利于设备维护的不足之处。

下面进一步结合附图2,以RFID设备做为待连接设备,对本方法进行进一步的详细说明。基于RFID的SDK设计程序架构如果所示,主要有3部分构成
①待连接设备,例如:RFID硬件设备,通过硬件通信接口,例如:串口与主板进行数据通讯。
②主板设备驱动程序
③应用层程序,包括SDK
工作流程:待连接硬件设备,例如:RFID硬件设备与SDK按照规定的协议进行通讯,读写标签及设置模块的各种性能参数;底层驱动程序采用透传模式,只对数据包进行判断,不对数据进行处理,增强了程序的灵活性;SDK通过动态链接库文件提供的接口函数,例如:so文件提供的Native()函数控制RFID硬件设备,实现设备硬件通信接口打开/关闭,收发数据,及通过控制脚控制模块的各种工作模式;SDK将RFID的工作流程封装,提供接口函数供用户调用,用户不要知道RFID的工作流程,及可以操作RFID模块。

SDK文件对外提供多种接口函数,例如:RFID设备接口函数、条形码识别器接口函数,用户通过这些函数实现设备功能。
最后,特别声明下,本发明中所提到的几个常用的英文缩写的具体定义如下:
SDK:Software Development Kit即软件开发工具包;RFID:Radio Frequency Identification即无线射频识别设备。
以上对本发明及其实施方式进行了描述,该描述没有限制性,附图中所示的也只是本发明的实施方式之一,实际的结构并不局限于此。总而言 之如果本领域的普通技术人员受其启示,在不脱离本发明创造宗旨的情况下,不经创造性的设计出与该技术方案相似的结构方式及实施例,均应属于本发明的保护范围。
