控制器模块 17中， 该模块包含无线数据通信控制模块和存储控制模块， 所述无 线数据通信控制模块和存储控制模块可以是独立的， 也可以合二为一。 所述控制器 模块 17 中固化有第一固化软件； 其主要功能在于： 通过标准 RS232 串口完成与无 线收发模块 8之间的通信； 同时兼有对串行、 并行或无线通信接口的控制功能， 并 通过接口模块 5完成与主机之间的通信。 如图 7所示， 本模块采用一块 64HN的专 用处理器芯片 U5， U5是具有 USB接口控制功能的微处理器， 图中 XT2为 6MHz 晶振。 所述控制器模块 17中还固化有第二固化软件。 其主要功能在于： 控制接口， 完成与接口模块 5之间的通信， 同时作为存储介质 (如快闪存储器)模块 11的主控制 芯片， 控制对存储介质的读写擦除等操作。 如图 11所示， 本模块采用一块 64PIN的 NT2007专用微处理器芯片 U9， U9是具有 USB接口控制功能的微处理器， 图中 XT3 为 8MHz晶振。 所述第一固化软件和所述第二固化软件可以是独立的， 也可以合二 为一。
当所述控制器模块 17中无线数据通信控制模块和存储控制模块是独立的时， 接 口模块 5与 USB HUB模块 6相连。 USB HUB模块 6的主要功能是给控制器模块 17 提供两个下行 USB端口分别连接所述控制器模块 17中的无线数据通信控制模块和 存储控制模块，完成控制器模块 17和接口模块 5之间的通信。如图 6所示， USB HUB 模块 6采用 NT005芯片来实现 USB HUB功能， 芯片 NT006是 NT005的电流保护 芯片， 外接 6MHz的时钟频率。

本发明中的固化软件是软件和硬件的结合部分， 是固化在微控制器中的软件， 微控制器上电复位后， 通过运行固化在其中的固化软件， 从而完成设计者需要的一 系列操作， 固化软件在本发明的应用系统中所处的地位、 与操作系统和驱动程序的 关系如图 13所示， 本发明的驱动程序运行在电脑主机系统的操作系统内。
第一固化软件主要完成的功能包括：
a. 上电初始化， 微控制器的串行端口配置为串行收发中断， 串行波特率可以是 9600 bit/s;
b. USB系统的配置， USB接口配置为消息传递接口及数据接口， 消息传递接口 定义为中断传输， 数据接口定义为批量传输； 厂商自定义类 (lass)—个， 目的是传递 用户识别码；
c控制无线收发模块 8;
d.完成数据在无线收发模块 8与 USB接口之间的双向传输。
本发明使用 32K SRAM作为数据缓存， 收发数据的速度大大增加。
第一固化软件的工作流程如图 14所示：
当用户将本发明的无线数据通信装置插入到电脑的相应接口时， 在上电的同时 操作系统自动寻找设备驱动程序， 微控制器立即开始执行固化在其中的固化软件， 包括如下步骤：
a.将微控制器及其外围接口芯片进行初始化；
b.操作系统会查询 USB接口芯片控制管道， 此时 USB接口芯片会产生中断给 微控制器， 然后微控制器通过操作 USB接口芯片与操作系统取得联系。 通过一系列 的标准 USB配置， 使得与本发明的无线数据通信设备相适应的全部驱动程序 (Driver) 得到加载； W c.通过厂商自定义的配置的请求， 微控制器来访问识别码模块 3， 从而给操作 系统一个唯一的号码， 这个号码在应用程序中将得到灵活的应用。 比如身份认证、 加密等。 微控制器根据操作系统的请求来控制无线收发模块 8的工作状况；
d. 当有数据传输请求时， 微控制器将数据在底层操作系统与无线收发模块之间 传送。
本发明的第二固化软件的工作流程图如图 15所示， 本发明无线数据通信和存储 装置接入数据处理系统后， 固化软件即对装置初始化并指示操作系统科移动存储装 置配置， 然后等待操作请求， 分别处理标准的 USB操作和快闪存储器特定操作， 然 后将处理结果或状态等信息返回， 经 USB接口返还给主机操作系统协助完成标准的 USB操作和快闪存储器特定操作， 继续等待操作请求。
本发明可以带有驱动程序， 所述驱动程序可以实现通信功能和存储功能。 一般 而言， 普通的驱动程序提供连接到计算机硬件的软件接口， 并被作为操作系统的一 部分加载， 这样用户应用程序即可以一种规范的方式访问硬件， 而不必考虑如何控 制硬件。 本发明的驱动程序也提供了这样的功能， 它使应用程序通过通用的编程接 口来操作本发明的设备， 例如无线数据收发驱动程序具有完成建立网络连接， 收发 短消息等功能， 同时还具有和主机的操作系统配合处理硬件设备的安装、 拔除等活 动的功能； 该驱动程序优先采用 USB标准， 为提高本发明产品的通用性和稳定性， 其不同于普通电脑外部设备的驱动程序的主要任务之一是将 USB接口的数据格式映 射成 RS232 串行接口的数据格式， 这样从操作系统和应用程序的角度来看， 本发明 是一个串行设备， 理论上传统的基于串行口的应用程序不加修改就可以应用于本发 明； 这就要求由本发明的驱动程序创建一个虚拟的 RS232 串行接口。 此外， 该驱动 程序还必须处理诸如多端口安装、 突然拔除设备等情况。
以下给出创建虚拟串行端口的几个关键步骤：
步骤一： 编写一个总线驱动程序 (Bus Driver), 它将为本发明提供功能驱动并枚 举一个串行口的物理设备对象 (PDO Physical Device Object)。 创建一个虚拟串行端口 的第一步是在该驱动程序中枚举它， 并在收到适当的通知后， 建立一个新的设备对 象宋代表这个虚拟端口。
虚拟端口创建之后， 总线驱动程序要通过调用 Iolnvalidate Device Relations通知 输入输出管理器 (10 Manager), 然后在收到 IRP— QUERYJD时返回唯一的硬件标识 符 (Unique Hardware ID)。 这将确保在安装过程中提示用户选择新的安装文件的位置。 同时驱动程序必须在收到 IRP—MN— QUERY— CAPABILITIES 时将此设备标识为原始 设备。
步骤二：
提供安装文件安装此新设备， 并告诉输入输出管理器， 在设备堆栈中没有功能 驱动程序 (Function Driver)。 因为这是一个原始设备， 所以将输入输出请求包直接交 由新建的物理设备对象处理。
步骤三：
为使旧有的基于串行口的应用程序能够访问本发明的设备， 还需：
1. 收到 IRP _MN_ START_DEVICE 时创建一个指向虚拟端口设备的符号名连 接；
2.在注册表中串口映象位置创建类型为 REG— SZ的注册表项， 其名称为虚拟端 口设备的设备名， 其数值为类安装服务提供者指派的虚拟端口设备的端口号。
步骤四：
现在驱动程序可以开始从任何串行口应用程序 (如超级终端 Hyperterminal, 拨号 网络 Dial— Up Networking等)接收输入输出请求包了， 通过处理各种串行控制输入输 出请求包 (Serial IOCTL IRPs), 虚拟端口将成为全功能的串行端口。
以上说明中 IRP_XXX表示输入输出请求包的名称， 其余未加说明的均为函数 名， 如 IoRegister Device Interface等。
USB协议支持设备热插拔， 但在安全拔除设备前， 用户应当首先运行安全移除 硬件程序 (Safely Remove Hardware application)，该程序将通知操作系统 (例如 Windows) 用户试图删除设备， 操作系统将中止当前的数据传输并卸载设备驱动程序。 如果用 户直接拔除设备而未事先运行安全移除硬件程序 (这通常被称之为突然拔除 Surprise Removal), 将有可能造成数据丢失或系统崩溃， 因为此时应用程序还持有设备句柄 (Device handle), 而这是即插即用管理器 (PnP Manager)所不允许的。 本发明在驱动程 序中解决了此问题， 即可通知应用程序在适当的时候释放设备句柄。
Windows 2000和 Windows 98提供了一种方法来通知用户模式和内核模式部件 刚发生的即插即用事件， 使得应用程序可以通过处理消息 WM—DEVICECHANGE来 监视或控制系统中的硬件和电源配置的改变， 还可以容易地检测到某驱动程序允许 或禁止寄存的设备接口。
其具体实现可分为设备驱动程序和应用程序两部分： 设备驱动程序： 在物理设备对象收到 IRP MN-START DEVICE时， 通过调用 Io egisterDevice erface函数来注册一个接口 GUID(GloballyUniqueldentifier) , 然后 调用 IoSetDevicelnterfaceState函数允许该接口。
应用程序： 创建或使用现有的含有窗口及消息循环的线程， 在其中调用 RegisterDeviceNotification函数， 这样 PnP管理器会在任何人允许或禁止驱动程序接 口 GUID 时向窗口发送一个 WM— DEVtCECHA GE消息， 现在， 应用程序应注意 wParam(事件代码）等于 DBT— DEVICEQUERYREMOVE ， devicetype 为 DBT—DEVTYP— HANDLE的 WM—DEVICECHANGE消息。 该消息意味着接口将要 被禁止， 因此应该关闭所拥有的设备句柄。 然后在该消息的处理程序中无条件地返 回 TRUE。
本发明装置可多端口安装， 多端口安装是指同一台数据处理系统带有多个本发 明的无线数据通信设备， 此时存在并发访问， 并发访问允许应用程序使用异步访问 方式来读写同一设备， 这样可以提高设备利用率， 增加系统的输入输出吞吐量。 使 用该技术， 本发明可以批量的收发短信而不会被阻塞， 这种功能很适合用于集团用 户使用。 并发访问的实现： 首先创建设备对象时需指定独占模式 (Exclusive mode), 其次在收到上层软件 (应用程序)的读写请求 (IRP—MJ— READ和 IRP— MJ—W ITE)时， 对其进行排队， 并在合适的时机完成它们。
本发明的存储驱动程序的流程如图 16所示。 所述驱动程序控制本发明的移动通 信设备完成初始化并指示操作系统可移动存储装置配置， 在通过用户认证后等待操 作请求， 并将写存储模块 11(可采用快闪存储器)的操作请求进行处理， 对存储操作 命令进行 USB打包并通过操作系统发给固化软件， 同时处理即插即用或者其它所支 持的操作。 在本发明的装置拔出以前始终等待操作请求， 拔出后指示操作系统消除 可移动存储装置配置。 实现通信功能的驱动程序和实现存储功能的驱动程序可以是 独立的， 也可以是合二为一的。
本发明可采用 USB接口与主机相连、 可热插拔， 融合通用串行总线、 移动存储 技术及移动通信技术， 直接使用移动电话公司提供的通信服务， 可实现无线移动电 话、 电脑之间的数据传输， 提供了优异可靠的移动存储和无线通信性能及无线上网 功能， 可以接收和发送无线数据信息， 包括语音、 数据、 短信息、 控制信息等。 本 发明装置能使计算机成为因特网的公用无线网络终端。
本发明可以通过 USB总线直接供电 (4.5V-5.5v)， 满足 USB1.1/2.0标准。 可适用 于 GSM、 GPRS、 CDMA, WCDMA、 CDMA2000、 CDPD等无线通信网络。 集成 电子身份证功能， 每个本发明的无线数据通信设备都有一个独一无二的序列号。
本发明可应用于银行、 证券、 保险、 期货等金融领域， 将原来的有线联网方式 改为无线连网方式， 速度更快、 安全度更高、 使用更方便， 费用更节省。 本发明也 可应用于民航、 铁路、 公安、 环保、 石化、 航运等行业部门， 如远程售票、 远程监 控等。
