具体实施方式
为详细说明本申请的技术内容、构造特征、所实现目的及效果，以下结合实施方式并配合附图详予说明。
实施例一
参阅图1，本申请的一具体实施例为：一种可靠的低功耗通信方法，用于设备端与网关之间进行无线通信，所述通信方法包括，
S10、定期同步网关与设备端之间的时间节拍基准，以使网关与设备端的TX窗口与RX窗口精准对齐；

本实施例中，网关在添加设备时，通过通信协商初始时间基准，将当前设备的初始时间基准值记录到设备信息表，设备信息表包含设备ID、设备时间基准值、基准偏移值等信息。在网关需要与设备进行通信时，会查询设备信息表获取时间基准值及基准偏移值，计算下一个通信窗口的时间点，网关与设备端在下一个通信窗口的时间点进行通信。
在网关收到设备端主动上报的信息时，会打断设备的基准计时，网关需要在完成与设备端的通信后再重新协商通信时间基准并更新到设备信息表中，网关与设备端从此按照新的基准时间进行通信。
在网关接收到通信请求时，网关不会立刻与设备端进行通信，而是设备端在进入下一个通信窗口时间点时，网关再与其进行通信，不需要网关持续发送数据而造成信道拥挤，最大限度的减少了无效通信，一个或多个设备端通过dutycycle的方式进行周期性的休眠及周期性的打开RF、RX窗口，从而做到极低功耗的设备端待机功率。

参阅图5，网关需要定期与设备同步节拍(更新时间基准)，以保证网关的TX窗口总是与设备的RX窗口精准的对齐，从而确保数据可以可靠的到达设备。
由于网关与设备运行不同的操作系统，不同的硬件，因此两者间RF部分打开关闭的节拍随着时间的推移不可避免的存在一定的误差，我们根据实际测试以及 理论计算得到一个需要定期同步的经验值T。每次同步后，网关与设备按照新的节拍进行通信。
网关通过给设备发送特殊数据包的方式进行同步，设备在收到该指令后回复一个响应给网关然后马上按周期进行休眠，网关在收到响应后记录当前时间点，此时间点则作为网关与设备通信的基准时间点，从此网关与设备基于该基准时间点按周期进行通信。
