一种便携式多目标通讯装置及通讯方法 技术领域
本发明涉及通讯技术领域，尤其涉及一种便携式多目标通讯装置及通讯方法。
背景技术
想在新年第一天看到最美的日出，12名没有专业装备和登山经验的大学生决定登上海拔2434米的雪山赵公山顶峰。因预期不足、体力不支，其中8名大学生被困山上。大学生朝气蓬勃，把登山探险作为一种时尚的社会实践活动，本身并没有错，然而却屡屡出现大学生“驴友”野外被困的报道。这一现象暴露出来的问题不得不引起重视。一方面是缺乏自救的意识和团队互相帮助的经验，而另一方面，现有的通信设备依赖于GPS和无线通信信号，当在山区或者旅游风景区，信号塔信号传输差，信号覆盖范围小等原因，导致登山时携带的设备无法及时与外界保持联系。
量子纠缠是两个或多个粒子共同组成的一种量子状态。无论这些粒子之间相隔多远，只要一个粒子发生变化，另外的粒子也会即刻“感知”，也随之发生变化。2017年6月16日，量子科学实验卫星墨子号首先成功实现，两个量子纠缠光子被分发到相距超过1200公里的距离后，仍可继续保持其量子纠缠的状态；2018年4月25日，芬兰阿尔托大学教授Mika

  2. 一种权利要求1所述的便携式多目标通讯装置之间的通讯方法，其特征在于，该方法的步骤具体如下：
    (1)多个通讯装置中，每个通讯装置都有自己唯一的ID，任意两个装置之间建立量子纠缠关系，并保证任意两个装置之间可以相互通讯；若当前纠缠量子对遭到破坏，使用备份中的下一组量子纠缠对进行通讯；通过相互纠缠的量子对构成通讯网络，该通讯网络用于指定ID快速得到对方的状态信息；
    (2)装置将GPS和惯性传感器与发送单元的纠缠量子端进行耦合，然后用耦合的纠缠量子进行数据传送；
    (3)每个通讯装置之间每隔一定时间按照ID顺序自动互相进行数据收发，具体为，向其他ID装置发送自身的状态信息，在发送完信息之后，接受该装置的状态信息，并将自身和该装置的状态信息按照时间序列进行记录，发送和接收完成后，依次与下一ID装置进行数据收发，直到遍历所有装置；
    (4)通讯装置能够根据指定的ID，发送并读取指定ID装置的状态信息，即相对于循环遍历的方式，有更高的优先级，但自动遍历仍在后台运行，不会打断遍历的顺序；
    (5)通讯装置和智能终端相连，用于将当前装置和接收的其它ID装置的状态信息在离线地图上显示，绘制出当前装置和其他ID装置的行进路径以及当前在地图上的位置，根据装置中接收单元读取与GPS相对应的纠缠量子的状态信息，来判断是否可以接收GPS信号；当能接收GPS信号时，状态信息是由GPS和惯性传感器共同获得，当不能接收GPS信号时，状态信息只由惯性传感器获得。
  3. 一种权利要求1所述的便携式多目标通讯装置与基站之间的通讯方法，其特征在于， 该方法的步骤具体如下：
    (1)多个通讯装置中，每个通讯装置都有自己唯一的ID，基站中包含与通讯装置之间建立量子纠缠关系的接收端和发送端，每个装置均与基站之间建立量子纠缠关系，并保证任意装置和基站之间可以相互通讯；若当前纠缠量子对遭到破坏，使用备份中的下一组量子纠缠对进行通讯；通过多组相互纠缠的量子对构成通讯网络；
    (2)装置将GPS和惯性传感器与发送单元的纠缠量子端进行耦合，然后用耦合的纠缠量子进行数据传送；
    (3)每个通讯装置每隔一定时间按照ID顺序自动与基站进行数据收发，向基站发送自己的状态信息，当所有的通讯装置都向基站发送状态信息之后，基站进行记录，然后按照ID顺序依次与每个通讯装置进行数据收发，发送所有装置的状态信息；
    (4)通讯装置和智能终端相连，用于将当前装置和接收的基站的数据信息在离线地图上显示，绘制出当前装置和其他ID装置的行进路径以及当前在地图上的位置，根据装置中接收单元读取与GPS相对应的纠缠量子的状态信息，来判断是否可以接收GPS信号；当能接收GPS信号时，状态信息是由GPS和惯性传感器共同获得，当不能接收GPS信号时，状态信息只由惯性传感器获得。
