本申请要求2018年03月23日递交的申请号为201810249361.8、发明名称为“资源分配方法及相关设备、系统、存储介质”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请一般涉及无线通信技术领域,具体涉及电子标签技术领域,尤其涉及资源分配方法及相关设备、系统、存储介质。
背景技术
RFID(Radio Frequency Identification)技术是20实际90年代兴起的一种自动识别技术,在无需申请许可证的2.4GHz ISM(Industrial Scientific Medical)波段运行,带宽较宽,可利用资源多,且具有较其他频段更强的抗干扰能力。作为一种开放性的无线通信标准,它亦可以取代目前多种电缆连接方案,通过统一的短程无线链路,在各信息设备之间共享信息资源,实现方便快捷、灵活安全、低成本小功耗的话音和数据通信,但是该公共频段还被其他不同标准的无线网络使用,例如WIFI。因此,导致实际应用场景中该公共频段的可用信道资源非常稀缺。
现有布设基站时,采用人工方式分配信道资源,仅简单规避WIFI常用信道资源,且由于不同区域的无线环境存在差异,通过人工方式进行信道分配,实施效率低,无法根据真实的无线环境利用可用信道资源,还导致基站并发度少,基站通信效率低下。
发明内容
鉴于现有技术中的上述缺陷或不足,期望提供一种在电子标签通信前能够根据无线环境动态分配无线信道资源的技术方案。
第一方面,本申请实施例提供了一种无线资源分配的方法,该方法由中心管理设备执行,该方法包括:
获取第一信息集合,该第一信息集合包括待分配资源的基站群中任一基站监测的、基站群中的其他基站在预定的第一无线信道资源上无线广播的能量信息;
基于能量信息确定基站群中各基站之间的距离关系;以及
基于距离关系为基站群中每个基站分配与之对应的第二无线信道资源,该第二无线信道资源用于基站与其关联的至少一个电子标签建立通信。

具体实施方式
下面结合附图和实施例对本申请作进一步的详细说明。可以理解的是,此处所描述的具体实施例仅仅用于解释相关发明,而非对该发明的限定。另外还需要说明的是,为了便于描述,附图中仅示出了与发明相关的部分。
需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
电子标签也可以称为电子价签,或者电子货架标签(Electronic Shelf Label,ESL)。其具有快捷、准确的价格显示功能,能够提高客户的满意度。一套完整的电子标签系统,至少包括基站(或称为无线接入点)、电子标签、中心管理设备(也可以称为服务器系统)等。
本申请实施例的电子标签系统包括多个中心管理设备,多个基站以及归属各基站的多个电子标签,中心管理设备负责给各个基站分配无线信道资源以防止基站之间的相邻干扰。基站与归属该基站的各个电子标签使用预先分配的无线信道资源建立通信。由于现实应用场景中存在多个基站,例如50个以上,其管辖的电子标签总量约50000个以上,当基站附近存在不同程度的干扰,其可能导致基站所管辖的电子标签都无法避免地存在干扰。
本申请实施例通过中心管理设备针对能量信息来分析布设基站实际所处的无线环境,然后基于该环境动态地为基站分配无线信道资源。
请参考图1,图1示出了本申请实施例的电子标签通信的应用场景的示意性框图。
在图1所示的应用场景中,可以包括中心管理设备110,基站群包括多个基站,例如可以是基站120,121,122,123,124,125以及与其相关的多个电子标签,例如电子标签120-1,120-n,121-1,121-n,122-1,122-n,124-1,124-n,125-1,125-n等。
如图1所示,中心管理设备110,用于管理和调度各个基站和电子标签。基站120,121,122,123,124,125分别用于与其关联的电子标签进行通信,并执行信道扫描、跳频通信等功能。
其中,电子标签120-1,120-n归属基站120,电子标签121-1,121-n归属基站121等。
在图1所示的应用场景中,基站附近可能存在相同频段的其他无线网络的干扰,例如,干扰源E,F。这些干扰源可能是长期的,也可能是短暂或暂时的。考虑到2.4GHz 频段的信道资源有限,针对长期存在或短期存在的干扰源,期望能够提供一种应用于电子标签系统的无线资源管理方法,来动态调整无线资源,以实现电子标签通信协议与同频段其他通信协议的共存。
基于图1所示的应用场景,本申请实施例提出一种应用于电子标签系统的无线资源分配方法。
请参考图2,图2示出了本申请实施例提供的应用于电子标签系统的无线资源分配方法的流程示意图。
如图2所示,该方法包括:
步骤220,中心管理设备向待分配资源的基站群中每个基站发送第一信息指令,该第一信息指令用于指示基站群中每个基站在第一无线信道资源上有序地进行无线广播;
本申请实施例中,待分配资源的基站群,例如基站120,121,122,123,124,125,通过中心管理设备统一分配信道资源。中心管理设备先分别向待分配资源的基站群中的每个基站发送信息指令,该信息指令指示基站在第一无线信道资源f 1上有序地进行无线广播。该信息指令可以广播信道指示指令,或者携带广播信道资源的其他指令。
步骤240,基站群中任一基站向中心管理设备上报的第一信息集合,该第一信息集合包括待分配资源的基站群中任一基站监测的、基站群中的其他基站在预定的第一无线信道资源上无线广播的能量信息。
本申请实施例中,中心管理设备接收到基站上报的第一信息集合,每个基站都负责监测其他基站在第一无线信道资源f 1上无线广播的能量信息,并在获得监测结果之后,将其监测的其他基站的能量信息整合打包处理后,主动上报给中心管理设备。基站120上报的第一信息集合,例如可以包括{B 120-121,B 120-122,B 120-123,B 120-124,B 120-125},基站121上报的第一信息集合,例如可以包括{B 121-120,B 121-122,B 121-123,B 121-124,B 121-125},基站122上报的第一信息集合,例如可以包括{B 122-120,B 122-121,B 122-123,B 122-124,B 122- 125}等等,其中,B 120-121为基站120接收到基站121广播的信号的能量信息,B 120-122为基站120接收到基站122广播的信号的能量信息,其他理解类似。
中心管理设备接收到上报的信息集合之后,处理并获取各自的能量信息,用以判断基站之间的距离关系。
步骤260,中心管理设备基于能量信息确定基站群中各基站之间的距离关系;然后,基于距离关系为基站群中每个基站分配与之对应的第二无线信道资源,其中,第二无线信道资源用于基站与其关联的至少一个电子标签建立通信。
本申请实施例中,中心管理设备在接收到上报第一信息集合后,其处理器进一步获取第一信息集合进行分析判断。
中心管理设备基于能量信息可以判断出基站之间的相对距离,然后根据这样的相对距离为距离相关的基站分配的无线信道资源,从而使得距离相关的基站可以无干扰的与其相关的至少一个电子标签进行通信。
其中,能量信息可以是基站监测其他基站的能量值信息,例如可以是通过能量检测算法得到的能量值。
基于能量信息判断距离,例如可以通过能量值与预设能量阈值进行判断,或者通过能量值是否位于预设的能量阈值区间来判断。能量阈值区间可以根据机器学习算法学习得到,也可以根据工程经验预先设定。能量值越大则说明干扰越严重,或者正在进行无线通信,能量值越小则说明干扰程度越小。例如,对基站120上报的第一信息集合{B 120- 121,B 120-122,B 120-123,B 120-124,B 120-125}进行判断。
以判断能量值位于预设的能量区间为例,预设的能量区间例如可以是[0,60db],[60db-80db],[80db-100db],以及[100db,+]。当B 120-121位于[100,+]内,表示基站120和基站121距离很近,需要采用不同频段的无线信道资源,且不同频段还需要间隔较大。当B 120-121位于[0,60db]内,表示基站120和基站121距离较远,即使采用同频段的无线信道资源,也不会导致信号干扰。
步骤280,基站接收中心管理设备分配的第二无线信道资源。
本申请实施例,中心管理设备基于距离关系为基站群中每个基站分配与之对应的第二无线信道资源,该第二无线信道资源可以作为基站与其关联的至少一个电子标签的默认信道资源,通常情况,基站与其关联的电子标签是采用默认信道资源建立通信的,在当前通信结束后也不会更改默认资源。但是,默认信道资源可能随着无线环境的变化受到不同程度的干扰,从而导致中心管理设备分配的资源不能正常使用。
为了克服基站周边其他无线设备产生的干扰问题,本申请实施例还可以基于变化的无线环境调整默认无线信道资源,以提高系统的通信效率。
可选地,该方法还可以包括:
步骤290,由中心管理设备响应于触发事件来获取与该触发事件对应的预设时间范围的信道扫描结果,其中,信道扫描结果包括针对预先为基站群中每个基站分配的与之对应的第二无线信道资源的监测结果,该第二无线信道资源用于基站与其关联的至少一个电子标签建立通信;
基于与该触发事件对应的预设时间范围的信道扫描结果判断该第二无线信道资源存在的干扰类型;
基于干扰类型生成信道指示消息,其中,信道指示消息包括第三无线信道资源,该信道指示消息用于指示基站与其关联的至少一个电子标签针对第三无线信道资源的使用权限。
本申请实施例中,触发事件例如可以是中心管理设备110从基站120,121接收到上报的信道扫描结果和/或来自外部应用系统针对电子标签120-1,120-n和/或121-1,121-n的电子标签请求指令。
中心管理设备110在接收到基站上报的信道扫描结果时,或者中心管理设备110在接收到外部应用系统针对电子标签的电子标签请求指令时,会通过事件触发的方式,使得中心管理设备110的处理器获取与触发事件对应的预设时间范围的信道扫描结果。例如,触发事件是基站120上报信道扫描结果,中心管理设备110在接收到基站120上报的信道扫描结果时,触发中心管理设备110获取预定时间范围的信道扫描结果,然后中心管理设备110基于预设时间范围的信道扫描结果来判断预先为基站120分配的第二无线信道资源f 120是否存在干扰以及存在干扰类型。预设时间范围可以是过去24小时内基站120上报的信道扫描结果,对于具体时间的限定此处只是为了更好地理解本申请,不作任何限定。
再例如,触发事件例如可以是中心管理设备110接收到外部应用系统针对电子标签121-1,121-n的电子标签请求指令,触发中心管理设备110获取预定时间范围的信道扫描结果,然后中心管理设备110基于预设时间范围的信道扫描结果来判断预先为基站121分配的与之对应的第二无线信道资源f 121是否存在干扰以及存在干扰类型。预设时间范围可以是接收到触发事件之前的4小时内基站121上报的信道扫描结果,对于具体时间的限定此处只是为了更好地理解本申请,不作任何限定。
中心管理设备110的处理器基于获取的预设时间范围的信道扫描结果判断第一无线信道资源存在的干扰类型,然后根据干扰类型生成信道指示消息,并在信道指示消息中包括第三无线信道资源,用于指示基站与归属该基站的至少一个电子标签根据信道指示消息指示的第三无线信道资源的使用权限建立通信。
以判断第二无线信道资源f 120存在干扰类型为例,进一步说明本申请的实施例。
当中心管理设备110的处理器判断第二无线信道资源f 120存在长期干扰时,则分配第三无线信道资源f 120’,并指示基站121在使用第三无线信道资源f 120’与电子标签120 - 1,120 -n通信完成之后,将第三无线信道资源f 120’作为基站120与电子标签120 -1,120 -n之间默认的信道资源,并下次启动通信时,直接采用该第三无线信道资源f 120’进行通信,从而保证基站120与电子标签120 -1,120 -n之间的通信。
当中心管理设备110判断第二无线信道资源f 120存在短期干扰时,则分配第三无线信道资源f 120’,并指示基站102在使用第三无线信道资源f 120’与电子标签120 -1,120 -n通信完成之后,释放第三无线信道资源f 120’。下次启动通信时,仍然采用第二无线信道资源f 120进行通信,从而保证基站120与电子标签120 -1,120 -n之间的通信。
本申请实施例中,中心管理设备110会针对其管理的基站逐一判断,并根据判断结果逐一调整资源,从而实现针对性的跳频策略控制,动态调整通信资源,以保证通信效率。
可选地,该方法还可以包括:
基站从中心管理设备接收信道指示消息,然后,控制与其关联的至少一个电子标签按照信道指示消息指示的第三无线信道资源的使用权限建立通信。
本申请通过基站上报的能量信息分析,基站之间距离关系,并根据距离关系合理分配资源,实现资源的复用,提高了系统的并发度,提升了信道利用率。进一步地提供了信道资源的优化策略,基于干扰类型动态调整无线信道资源,从而有针对性的解决干扰问题。
基于图1所示的应用场景,本申请实施例提供一种无线资源分配方法。请参考图3,图3示出了本申请实施例提供的无线资源分配方法的流程示意图,该方法从中心管理设备110的角度进行描述。
如图3所示,该方法可以包括:
步骤310,获取第一信息集合,第一信息集合包括待分配资源的基站群中任一基站监测的、基站群中的其他基站在预定的第一无线信道资源上无线广播的能量信息。
本申请实施例中,在中心管理设备110接收各个基站120,121,122,123,124,125上报的各自的第一信息集合,该第一信息集合例如可以是{B 120-121,B 120-122,B 120- 123,B 120-124,B 120-125},其中,B为基站监测其他基站的在预定的第一无线信道资源上无线广播的能量信息。
步骤320,基于能量信息确定基站群中各基站之间的距离关系。
本申请实施例,中心管理设备从第一信息集合中获得各基站的能量信息,然后基于能量信息判断各基站的距离。例如可以通过能量值与预设能量阈值进行判断,或者通过 能量值是否位于预设的能量阈值区间来判断,或者将第一信息集合中的能量信息进行排序,然后根据排序结果来判断。
其中,预设能量阈值、能量阈值区间可以根据机器学习算法学习得到,也可以根据工程经验预先设置。能量值越大则说明干扰越严重,或者正在进行无线通信,能量值越小则说明干扰程度越小。
其中,能量阈值区间例如可以包括多个阈值区间。例如可以包括第一阈值区间[0,60db],第二阈值区间[60db-80db],第三阈值区间[80db-100db],第四阈值区间[100db,+]。其中,第一阈值区间对应的距离关系为第二距离关系,第二、三、四阈值区间、对应的距离关系为第一距离关系。本申请实施例可以将各基站之间的关系用距离关系来标识。距离关系又可以根据其影响频段使用的情况分位第一距离关系和第二距离关系。第一距离关系表示距离相关的两个基站分别采用不同的第二无线信道资源可以互不干扰地与其关联的至少一个电子标签建立通信。第二距离关系表示距离相关的两个基站分别采用相同的第二无线信道资源可以互不干扰地与其关联的至少一个电子标签建立通信。根据能量信息对应的不同阈值区间,第一距离关系还可以划分为多个子类型,例如第一子类型,第二子类型、第三子类型。
针对第二距离关系,待分配的无线信道资源可以是相同频段;针对第一距离关系,待分配的无线信道资源必须是不同频段,且不同频段之间要求存在一定的间隔。针对第一距离关系中第一子类型,待分配的无线信道资源之间的间隔可以较小,例如1M,或者2M。针对第一距离关系中第三子类型,待分配的无线信道资源之间的间隔可以较大,例如5M。
例如第二阈值区间对应的距离关系为第一子类型,表示两个基站的距离较远,干扰程度较小,所以待分配的无线信道资源需要满足间隔1M。第三阈值区间对应的距离关系为第二子类型,表示两个基站的距离相对于第一子类型近些,待分配的无线信道资源需要满足间隔要求更大,例如2M。第三阈值区间对应的距离关系为第三子类型,表示两个基站的距离相对于第二子类型近些,待分配的无线信道资源需要满足间隔要求更大,例如3M。
对于阈值区间的划分,频段间隔的具体数值1M,2M,3M都仅只作为示例性说明,不作具体限定。这些划分和取值可以根据具体环境调整设置。
优选地,能量信息包括能量值,并且基于能量信息确定基站群中各基站之间的距离关系,包括:
判断能量值所处的能量阈值区间;以及
根据能量值所处的能量阈值区间,确定与该能量值关联的两个基站之间的距离关系。
步骤330,基于距离关系为基站群中每个基站分配与之对应的第二无线信道资源,第二无线信道资源用于基站与其关联的至少一个电子标签建立通信。
本申请实施例,在步骤320判断基站之间的距离关系之后,可以根据距离关系对应的类型为基站分配无线信道资源。
根据能量信息位于预设的能量阈值区间的情况,可以判断得到基站之间的距离关系。当距离关系包括第一距离关系时,基于距离关系为基站群中每个基站分配与之对应的第二无线信道资源,可以包括:
以基站群中任一个基站作为基准基站,为该基准基站分配与之对应的第二无线信道资源;
为确定为第一距离关系的基站分配与之对应的第二无线信道资源,第二无线信道资源之间相差预设间隔频段,该预设间隔频段是与第一距离关系相对应的。
当第一距离关系包括至少两个子类型时,基于距离关系为基站群中每个基站分配与之对应的第二无线信道资源,可以包括:
以基站群中任一个基站作为基准基站,为该基准基站分配与之对应的第二无线信道资源;
为确定为前述子类型的基站分配与之对应的第二无线信道资源,第二无线信道资源之间相差预设间隔频段,该预设间隔频段是与前述子类型相对应的。
例如,中心管理设备110接收基站120上报的第一信息集合,该第一信息集合例如可以是{B 120-121,B 120-122,B 120-123,B 120-124,B 120-125}。基站120监测基站121的B 120-121位于[100,+]内,则表示基站120和基站121属于第一距离关系的第三子类型,第三子类型对应的无线信道资源的分配条件需要满足采用不同频段的无线信道资源,且不同频段之间需要间隔较大。
根据基站120与基站121的距离关系,如果中心管理设备为基站120分配第二无线信道资源f 2,则为基站121需要分配的第二无线信道资源至少应当满足f 2+间隔频段,间隔频段例如可以3M,5M等。
当距离关系包括第二距离关系时,基于距离关系类型为基站群中每个基站分配与之对应的第二无线信道资源,可以包括:
以基站群中任一个基站作为基准基站,为该基准基站分配与之对应的第二无线信道资源;
为确定为第二距离类型的基站分配与之对应的第二无线信道资源,第二无线信道资源相同。
例如,基站120监测基站121的B 120-121位于[0,60db]内,则表示基站120和基站121属于第二距离关系,第二距离关系对应的无线信道资源的分配条件可以是相同频段的无线信道资源。因为基站120与基站121之间的距离很远,即使采用同频段的无线信道资源,也不会导致信号干扰。
本申请实施例,在步骤360之后,还可以根据中心管理设备获取的触发事件来进一步对第二无线信道资源进行调整,来提高资源管理的效率。
可选地,该方法还可以包括:
步骤340,响应于触发事件来获取与该触发事件对应的预设时间范围的信道扫描结果,其中信道扫描结果包括针对预先为基站群中每个基站分配的与之对应的第二无线信道资源的监测结果,第二无线信道资源用于基站与其关联的至少一个电子标签建立通信;
步骤350,基于与该触发事件对应的预设时间范围的信道扫描结果判断第二无线信道资源存在的干扰类型;
步骤360,基于干扰类型生成信道指示消息,信道指示消息包括第三无线信道资源,信道指示消息用于指示基站与其关联的至少一个电子标签针对第三无线信道资源的使用权限。
在响应于触发事件来获取与该触发事件对应的预设时间范围的信道扫描结果同时,还获取与该触发事件对应的预设条件,或者响应于触发事件确定与该触发事件对应的预设条件,或者在接收到触发事件时进入默认的程序调用与触发事件对应的预设条件。这里的预设条件,例如可以是阈值。例如第一阈值和/或第二阈值。对于第一阈值和第二阈值的取值例如可以是根据系统历史统计的平均次数或根据经验设置的次数。取值方式这里不作限定。
基于与该触发事件对应的预设时间范围的信道扫描结果判断第一无线信道资源存在的干扰类型。
本申请实施例中,通过预设时间范围的信道扫描结果判断第一无线信道资源存在的干扰类型,从而确定基站的周边环境的实际情况。
可选地,基于与该触发事件对应的预设时间范围的信道扫描结果计算第一无线信道资源的干扰频度。
本申请实施例中,通过对预设时间范围内第二无线信道资源f 2,存在干扰次数进行统计,得到第二无线信道资源的干扰频度。
可选地,根据前述干扰频度与触发事件对应的预设条件进行比较来确定第二无线信道资源的干扰类型。
根据干扰频度与预设条件进行比较,来判断第二无线信道资源f 2存在的干扰属于哪种干扰,例如长期干扰,或短期干扰。
可选地,关于计算第二无线信道资源的干扰频度还可以包括:
从与该触发事件对应的预设时间范围的信道扫描结果中获取第二二无线信道资源的信道数据,其中信道数据至少包括实时测量接收信号指示强度和占空比;
通过接收信号指示强度和占空比识别第二无线信道资源的干扰状态;
计算该预设时间范围内存在干扰状态的次数与该预设时间范围内针对第二无线信道资源进行监测的总次数的比值,该比值作为干扰频度。
通过获取信道扫描结果中体现干扰问题的指标数据,例如可以是干扰测量信息、测量结果、接收信号指示强度、占空比等。以接收信号指示强度、占空比为例,
通过将信道扫描结果中的接收信号指示强度与预设的第三阈值进行比较,以及将信道扫描结果中的占空比与预设的第四阈值进行比较;
如果接收信号指示强度低于第三阈值且占空比高于第四阈值,则确定第二无线信道资源处于干扰状态。或者认为第二无线信道资源存在1次干扰。通过对预设时间范围的信道扫描结果进行统计分析,得到预设时间范围内第二无线信道资源出现的干扰次数,然后通过干扰次数与针对第二无线信道资源进行监测的总次数,可以确定第二无线信道资源在预设时间范围被干扰的程度,该程度与预设的第一阈值或第二阈值进行比较可以判断出第二无线信道资源的干扰环境。
可选地,关于判断第一无线信道资源的干扰类型还包括:

基于图1所示的应用场景,本申请实施例提供另一种应用于电子标签系统的无线资源分配方法。请参考图4,图4示出了本申请实施例提供的又一无线资源分配方法的流程示意图,该方法从基站的角度进行描述。
如图4所示,该方法可以包括:

本申请实施例中,基站120,121,122,123,124,125通过基站各自的接收装置从中心管理设备110接收各自的第二无线信道资源。然后利用第二无线信道资源与其相关的电子标签建立通信。
可选地,步骤460,向中心管理设备上报信道扫描结果,其中信道扫描结果包括针对预先分配的第二无线信道资源的监测结果,第二无线信道资源用于与其关联的至少一个电子标签建立通信。

可选地,步骤480,从中心管理设备接收信道指示消息,信道指示消息包括第三无线信道资源,其中,信道指示消息是由中心管理设备基于第二无线信道资源存在的干扰类型生成的,干扰类型是由中心管理设备基于响应于触发事件来获取与该触发事件对应的预设时间范围的信道扫描结果判断得到的。
本申请实施例中,信道指示消息包括第三无线信道资源,该信道指示消息是由中心管理设备基于第二无线信道资源存在的干扰类型生成的,干扰类型是由中心管理设备基于响应于触发事件来获取与该触发事件对应的预设时间范围的信道扫描结果判断得到的。
信道指示消息中还可以包括使用指示,或者根据信道指示消息获取对应的使用指示,该使用指示用于指示针对第三无线信道资源的使用权限。
可选地,该方法还可以包括:
控制与其关联的至少一个电子标签按照信道指示消息指示的第三无线信道资源的使用权限建立通信。
基站的接收装置接收到信道指示消息之后,触发基站的处理器利用信道指示消息提供的第三无线信道资源分别与其关联的电子标签建立通信。
例如,基站120与电子标签120 -1,120 -n使用第三无线信道资源f 3建立通信,并根据信道指示消息中的使用指示在通信完成之后修改第三无线信道资源f 3作为默认的信道资源,或者在通信完成之后释放第三无线通信资源f 3
即,若使用指示是第一使用指示,在与电子标签使用第二无线信道资源完成通信之后,修改第二无线信道资源作为第一无线信道资源;或者,若使用指示是第二使用指示,在与电子标签使用第二无线信道资源完成通信之后,释放该第二无线信道资源。其中第一使用指示和第二使用指示用于区别指示内容。对使用指示的形式不作任何限定。

本申请实施例中,通过基站的发送装置向归属的至少一个电子标签广播通知信道指示消息。
为了保证通信效率,进一步还可以通过增强广播信号的能量值或和/或延长广播的时间来广播通知信道指示消息。
本申请实施例,通过在变化的无线环境实时识别信道资源的干扰情况,提供智能化地跳频方案来解决电子标签系统与其他同频无线通信产品共存的问题,从而提升电子标签系统的通信效率。
基于图1所示的应用场景,本申请实施例提供了一种应用于电子标签系统的中心管理设备。请参考图5,图5示出了本申请实施例提供的中心管理设备的结构示意图。
如图5所示,该中心管理设备500可以包括:
第一获取单元510,用于获取第一信息集合,第一信息集合包括待分配资源的基站群中任一基站监测的、基站群中的其他基站在预定的第一无线信道资源上无线广播的能量信息。
本申请实施例中,在中心管理设备110接收各个基站120,121,122,123,124,125上报的各自的第一信息集合,该第一信息集合例如可以是{B 120-121,B 120-122,B 120- 123,B 120-124,B 120-125},其中,B为基站监测其他基站的在预定的第一无线信道资源上无线广播的能量信息。
确定单元520,用于基于能量信息确定基站群中各基站之间的距离关系。
本申请实施例,中心管理设备从第一信息集合中获得各基站的能量信息,然后基于能量信息判断各基站的距离。例如可以通过能量值与预设能量阈值进行判断,或者通过能量值是否位于预设的能量阈值区间来判断,或者将第一信息集合中的能量信息进行排序,然后根据排序结果来判断。
其中,预设能量阈值、能量阈值区间可以根据机器学习算法学习得到,也可以根据工程经验预先设置。能量值越大则说明干扰越严重,或者正在进行无线通信,能量值越小则说明干扰程度越小。
其中,能量阈值区间例如可以包括多个阈值区间。例如可以包括第一阈值区间[0,60db],第二阈值区间[60db-80db],第三阈值区间[80db-100db],第四阈值区间[100db,+]。其中,第一阈值区间对应的距离关系为第二距离关系,第二、三、四阈值区间、对应的距离关系为第一距离关系。本申请实施例可以将各基站之间的关系用距离关系来标识。距离关系又可以根据其影响频段使用的情况分位第一距离关系和第二距离关系。第一距离关系表示距离相关的两个基站分别采用不同的第二无线信道资源可以互不干扰地与其关联的至少一个电子标签建立通信。第二距离关系表示距离相关的两个基站分别采用相同的第二无线信道资源可以互不干扰地与其关联的至少一个电子标签建立通信。根据能量信息对应的不同阈值区间,第一距离关系还可以划分为多个子类型,例如第一子类型,第二子类型、第三子类型。
针对第二距离关系,待分配的无线信道资源可以是相同频段;针对第一距离关系,待分配的无线信道资源必须是不同频段,且不同频段之间要求存在一定的间隔。针对第一距离关系中第一子类型,待分配的无线信道资源之间的间隔可以较小,例如1M,或者2M。针对第一距离关系中第三子类型,待分配的无线信道资源之间的间隔可以较大,例如5M。
例如第二阈值区间对应的距离关系为第一子类型,表示两个基站的距离较远,干扰程度较小,所以待分配的无线信道资源需要满足间隔1M。第三阈值区间对应的距离关系为第二子类型,表示两个基站的距离相对于第一子类型近些,待分配的无线信道资源需要满足间隔要求更大,例如2M。第三阈值区间对应的距离关系为第三子类型,表示两个基站的距离相对于第二子类型近些,待分配的无线信道资源需要满足间隔要求更大,例如3M。
对于阈值区间的划分,频段间隔的具体数值1M,2M,3M都仅只作为示例性说明,不作具体限定。这些划分和取值可以根据具体环境调整设置。
优选地,能量信息包括能量值,并且基于能量信息确定基站群中各基站之间的距离关系,包括:
判断能量值所处的能量阈值区间;以及
根据能量值所处的能量阈值区间,确定与该能量值关联的两个基站之间的距离关系。
分配单元530,用于基于距离关系为基站群中每个基站分配与之对应的第二无线信道资源,第二无线信道资源用于基站与其关联的至少一个电子标签建立通信。
本申请实施例,在判断基站之间的距离关系之后,可以根据距离关系对应的类型为基站分配无线信道资源。
根据能量信息位于预设的能量阈值区间的情况,可以判断得到基站之间的距离关系。当距离关系包括第一距离关系时,基于距离关系为基站群中每个基站分配与之对应的第二无线信道资源,可以包括:
以基站群中任一个基站作为基准基站,为该基准基站分配与之对应的第二无线信道资源;
为确定为第一距离关系的基站分配与之对应的第二无线信道资源,第二无线信道资源之间相差预设间隔频段,该预设间隔频段是与第一距离关系相对应的。
当第一距离关系包括至少两个子类型时,基于距离关系为基站群中每个基站分配与之对应的第二无线信道资源,可以包括:
以基站群中任一个基站作为基准基站,为该基准基站分配与之对应的第二无线信道资源;
为确定为前述子类型的基站分配与之对应的第二无线信道资源,第二无线信道资源之间相差预设间隔频段,该预设间隔频段是与前述子类型相对应的。
例如,中心管理设备110接收基站120上报的第一信息集合,该第一信息集合例如可以是{B 120-121,B 120-122,B 120-123,B 120-124,B 120-125}。基站120监测基站121的B 120-121位于[100,+]内,则表示基站120和基站121属于第一距离关系的第三子类型,第三子类型对应的无线信道资源的分配条件需要满足采用不同频段的无线信道资源,且不同频段之间需要间隔较大。
根据基站120与基站121的距离关系,如果中心管理设备为基站120分配第二无线信道资源f 2,则为基站121需要分配的第二无线信道资源至少应当满足f 2+间隔频段,间隔频段例如可以3M,5M等。
当距离关系包括第二距离关系时,基于距离关系类型为基站群中每个基站分配与之对应的第二无线信道资源,可以包括:
以基站群中任一个基站作为基准基站,为该基准基站分配与之对应的第二无线信道资源;
为确定为第二距离类型的基站分配与之对应的第二无线信道资源,第二无线信道资源相同。
例如,基站120监测基站121的B 120-121位于[0,60db]内,则表示基站120和基站121属于第二距离关系,第二距离关系对应的无线信道资源的分配条件可以是相同频段的无线信道资源。因为基站120与基站121之间的距离很远,即使采用同频段的无线信道资源,也不会导致信号干扰。
本申请实施例,还可以根据中心管理设备获取的触发事件来进一步对第二无线信道资源进行调整,来提高资源管理的效率。
可选地,该中心管理设备500还可以包括:

可选地,关于计算第二无线信道资源的干扰频度还可以包括:

通过将信道扫描结果中的接收信号指示强度与预设的第三阈值进行比较,以及将信道扫描结果中的占空比与预设的第四阈值进行比较;
如果接收信号指示强度低于第三阈值且占空比高于第四阈值,则确定第二无线信道资源处于干扰状态。或者认为第二无线信道资源存在1次干扰。通过对预设时间范围的信道扫描结果进行统计分析,得到预设时间范围内第二无线信道资源出现的干扰次数,然后通过干扰次数与针对第二无线信道资源进行监测的总次数,可以确定第二无线信道资源在预设时间范围被干扰的程度,该程度与预设的第一阈值或第二阈值进行比较可以判断出第二无线信道资源的干扰环境。
可选地,关于判断第一无线信道资源的干扰类型还包括:
利用干扰频度与第一阈值进行比较;
如果干扰频度大于第一阈值,则确定第二无线信道资源存在长期干扰;或者,
利用干扰频度与第二阈值进行比较;
如果干扰频度大于第二阈值,则确定第二无线信道资源存在短期干扰。
基于干扰类型生成信道指示消息,其中,信道指示消息包括第三无线信道资源,信道指示消息用于指示基站与归属该基站的至少一个电子标签针对第三无线信道资源的使用权限。
本申请实施例中,根据第二无线信道资源存在的干扰类型,中心管理设备可以动态地为基站分配新的无线信道资源,以避免干扰影响,提升通信效率。
