图 1示出根据本发明拆卸监测装置的一种实施方式的结构示意图； 图 2示出根据本发明拆卸监测装置的另一种实施方式的结构示意图； 图 3示出根据本发明拆卸监测方法的一种实施方式的流程图； 图 4示出根据本发明方法另一种实施方式的流程图。 具体实施方式
下面通过具体实施方式结合附图对本发明作进一步详细说明。
图 1为根据本发明拆卸监测装置的一种实施方式的结构示意图，如图 1 所示， 该拆卸监测装置包括： 判断模块、 开关模块、 处理器和存储模块； 其中，
判断模块用于判断拆卸合法性；
开关模块用于在监控到非法拆卸、 即判断模块判定拆卸非法时， 向处 理器发出中断信号；
处理器用于在接收到来自开关模块的中断信号后记录非法拆卸信息； 存储模块用于存储处理器记录的所述非法拆卸信息。
本实施方式中， 该判断模块还用于监控是否输入授权码， 若监控到输 入授权码， 判断输入的授权码是否正确； 若输入的授权码正确， 判断为合 法拆卸； 若未监控到输入授权码或输入的授权码错误则判断为非法拆卸。
本实施方式中， 拆卸监测装置还可包括备用电源， 相应的， 开关模块 包括与保护壳接触的弹簧开关， 用于在保护壳被非法打开时启动该备用电 源供电。
本实施方式中， 开关模块与处理器的中断输入管脚相连， 开关模块在 保护壳被非法打开时触发低电平以产生中断。
本实施方式中， 开关模块还用于在监控到合法拆卸时， 启动备用电源 供电， 向处理器发出中断信号； 处理器还用于在接收到开关模块发送的所 述中断信号后记录合法拆卸信息； 存储模块还用于存储合法拆卸信息。
图 2为根据本发明拆卸监测装置的另一种实施方式的结构示意图， 其 为本发明在手持电子设备中的应用， 如图 2所示， 该拆卸监测装置包括： 主电源、 备用电源， 处理器、 存储模块、 键盘控制模块、 键盘、 LCD屏以 及开关模块等； 其中，
备用电源和开关模块， 用于配合手持电子设备的各功能模块， 通过程 序的判断和对存储模块的读写操作， 来监测是否非法拆卸。
开关模块硬件结构设计简单灵活， 本实施方式中可用一个接触式通断 开关的开关组合来实现。 开关模块一侧通过接触式弹簧开关与设备板级保 护壳接触， 另一侧连接到处理器的中断输入管脚， 当外壳被强制拆卸时， 弹簧开关与板级保护壳的连接通路断开， 启动备用电池供电， 供电部分包 括其自身的处理器和存储器， 该处理器和存储器可包括部分功能单元， 使 其保证主电源的断开不影响触发中断， 记录存储等监测功能的实现。 备用 电池的启动需要先于开关模块中开关的断开， 以保证处理器正常供电后， 中断的可触发性。 这取决于开关模块结构上的设计， 开关模块结构的设计 釆用两级开关， 非法拆卸时优先触发备用电池供电， 可通过简单的开关簧 片级联断开实现。 备用电源接管主电源履行一些供电职能， 通路断开触发 开关模块内部的开关接地处理， 从而把处理器的中断管脚置为低电平， 产 生中断。
本领域技术人员应该了解， 为了使处理器产生中断也可以釆用所公知 的一些技术如光电传感器等。 处理器通过判断中断源， 记录拆卸信息， 写 入存储模块中。 拆卸信息是人为规定的字符， 是系统判定为非法拆卸后， 存储到存储器内的信息， 如： "此设备被非法拆卸， 拆卸时间为： 2010年 4 月 19日 14时。"
如果厂商或售后服务人员拆卸， 则为合法拆卸， 厂商或售后人员需要 通过键盘控制模块和键盘输入唯一的拆卸授权码 (拆卸授权码由设备供应 商提供）， 从而触发键盘输入中断， 键盘输入中断程序中进行授权码正确与 否判断， 处理器中运行的程序起到判断模块的作用， 一种实施方式中， 若 授权码正确则可关闭拆卸监测功能， 软件进行中断使能关闭操作， 从而拆 卸时即使开关模块中断输入管脚为低电平， 也不会产生中断， 不会写入相 关拆卸信息到存储模块中。 另一种实施方式， 不关闭拆卸监测功能， 系统 可根据授权码的正确， 向存储模块写入合法的拆卸信息。 这样， 手持电子 设备被用户非法拆卸后， 一旦损坏， 售后服务或厂商可根据存储模块中记 录的非法拆卸信息， 不予保修或者不负责无法修复责任。

步骤 408: 监测键盘输入命令， 系统初始化后， 以键盘输入中断 INT2 触发方式监测键盘输入命令； 如果有正确命令符 （正确授权码）输入， 则 触发键盘输入中断， 进入步骤 414键盘输入中断程序； 如果没有命令符输 入， 则转到步骤 410继续执行程序；
步骤 410: 监测非法拆卸所触发的中断 INT1 , 非法拆卸， 即在没有授 权码输入或者输入授权码错误的情况下实施拆卸， 拆卸者无法得到合法授 权， 进行强制拆卸， 则由开关模块启动备用电池， 供电后， 开关模块接地 处理， 则把处理器中断输入管脚 INT1置为低电平， 从而触发中断 INT1 ; 若触发的 INT1转入步骤 412, 否则转入步骤 424;
步骤 412: 中断处理， 写入存储模块； 即触发 INT1中断后， INT1中断 程序根据检测到的输入授权码和当前时间， 记录非法拆卸以及拆卸时间等 相关信息， 存入存储模块中， 转入步骤 424;
步骤 414: 进行授权码比对， 判断输入的授权码是否正确， 若正确转入 步骤 418, 否则转入步骤 416;

步骤 418: 判断为合法拆卸， 软件关闭中断 INT1 , 开关模块即使在中 断输入管脚置为低电平， 也不会触发中断； 也可以不关闭中断 INT1 , 但监 测到中断时， 记录合法拆卸信息；
步骤 420: LCD提示可进行合法拆卸；
步骤 422: 用户实施合法拆卸， 向存储模块写入合法拆卸信息； 步骤 424: 继续执行程序；
步骤 426: 程序结束。
如果设备在保修期内损坏， 售后人员用专门的软件读取电子设备中的 存储模块内的信息， 以此来判断设备是否被用户非法拆卸过； 如果存储模 块中读出非法拆卸信息， 则根据设备情况， 厂商或供应商不承担因非专业 人员非法拆卸而引起的质量问题， 从而不附带保修保质责任； 如果存储模 块中没有存储非法拆卸信息， 则可按保质期保修保换。
