本实施例采用双向反馈的通信,防碰撞和重发机制使小无线设备传输过程更加稳定、健壮。本实施例使用了信道纠错编码机制,传输错误率极低;由于使用了AES滚码加密机制,有效防止真实数据被黑客破解和重放攻击。本实施例可以广泛地应用在各类物联网相关的应用场合,例如智能家居、智能楼宇等,经过信道Hamming编码后具有编码纠错功能。
本发明实施例还提供另一种基于Sub-GHz小无线射频的设备的绑定通信方法,首先配置好的云端设备、手机端、主机、第一通信单元和第二通信单元完成初始化,然后云端设备与手机端协商小无线设备的绑定并授权,手机与第一通信设备和第二通信设备之间的进入消息处理流程;
所述的消息处理流程包括绑定命令和解绑命令的处理流程,绑定命令和解绑命令对于主机是透明的,执行绑定命令和解绑定命令时同步返回主机;最后,第一通信单元和第二通信单元之间开始进行双向数据通信,并执行相应的场景动作。
在本实施例中,所述手机为可以连接第一通信单元和第二通信单元的第三方设备,在一些实施例中,该第三方设备还可以是平板电脑、可穿戴设备或者其他设备。
所述主机可为同时连接着第一通信单元和第二通信单元的控制器或控制电路等。
所述云端设备可为位于网络侧的设备,是可与分别与手机等第三方设备及主机连接的设备。
第一通信单元和第二通信单元之间开始进行双向数据通信包括发送步 骤和接收步骤:
发送步骤包括:
发送步骤一:原始数据经过加密,使得每次输出都是不同的随机数;
发送步骤二:对随机数进行编码后产生具有编码纠错功能的编码后数据;
发送步骤三:将编码后数据组成完整的一帧数据待发送;
发送步骤四:在信道空闲时段发送完整的一帧数据;
发送步骤五:发送数据后进入等待对方反馈ACK机制,如果在规定时间T内收到对方反馈ACK,则发射成功;如没有收到则进入重发机制;
发送步骤六:进行重发机制将继续重新发送相同数据帧;如果超过最大重发数则退出;
接收步骤包括:
接收步骤一:接收机收到数据后先解析帧,判别是否为有效设备ID;如校验无效则丢弃数据;有效则继续传递;
接收步骤二:经过信道解码纠错及校验后,如校验无效则丢弃数据;有效则继续传递;
接受步骤三:经过解码后,判别是否对应有效滚码;如无效则丢弃数据,有效则继续处理;
接受步骤四:继续判别数据是否是反馈ACK帧还是一般有效数据;如是反馈ACK帧则传递给发射端处理;如果是一般有效数据则上报给应用层处理;
接收步骤五:收到有效数据后产生一个ACK帧并发送。
在发送步骤一中,原始数据经过AES滚码加密。
在发送步骤二中,经过信道Hamming编码后产生具有编码纠错功能的编码后数据;在发送子步骤三中,将编码后数据再增加设备ID和网络地址 信息,组成完整的一帧数据。
在接收步骤二中:经过信道Hamming解码纠错及CRC校验后,如校验无效则丢弃数据;有效则继续传递。
在发送步骤四中,在发送前通过侦听信道的防碰撞机制,确定当前信道的空闲时段。
第一通信单元和第二通信单元是单个通信子设备或是若干个通信子设备的集合。
第一通信单元和第二通信单元的应用层负责保存绑定信息,绑定信息包括绑定的子设备和通信秘钥、每次上电初始化时调用的绑定接口和通知协议栈。
本实施例利用上述的小无线射频转绑定方式,具有如下优势:双向反馈的通信控制模式,使场景控制过程更加稳定、健壮。子设备之间绑定可以由用户自主选择,通信控制又不完全依赖主机。可以广泛地应用在各类物联网相关的应用场合,例如智能家居、智能楼宇等。经过信道Hamming编码后具有编码纠错功能。

步骤S101:原始数据经过加密产生随机数;这里的随机数即为加密后的数据,加密后的数据具有随机性,故可以称之为随机数。
步骤S102:对随机数进行编码后产生具有编码纠错功能的编码后数据;在本实施中这里的编码纠错能力的编码后数据可以携带纠错码,例如,前向纠错码或混合纠错码等,这样接收端可以基于纠错码对数据进行检错和纠错;
步骤S103:将编码后数据组成完整的一帧数据待发送;
步骤S104:在信道空闲时段发送完整的一帧数据;在本实施例中选择信道空闲时段发送,例如,通过信道侦听确定当前是否有其他设备占用信 道,若有则避退,在其他设备没有占用信道时,及信道空闲时发送数据,从而减少碰撞,提升了发送成功率。
步骤S105:发送数据后进入等待对方反馈确认字符ACK机制,如果在规定时间T内收到对方反馈ACK,则发射成功;如没有收到则进入重发机制;在本实施例中不仅会结合纠错来确保数据传输的成功率,为了确保数据的最终成功,还会结合重传机制,在无法进行纠错时,通过重传请求的发送等可以实现数据的成功传输,确保数据传输的稳定性。
步骤S106:进行重发机制将继续重新发送相同数据帧;如果超过最大重发数则退出。
