具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
应理解,本发明实施例的电力通信系统可以应用各种无线通信方案进行通信,例如:全球移动通讯系统(GSM,Global System of Mobile communication),码分多址(CDMA,Code Division Multiple Access)系统,宽带码分多址(WCDMA,Wideband Code Division Multiple Access Wireless)系统,通用分组无线业务(GPRS,General Packet Radio Service)系统,长期演进(LTE,Long Term Evolution)系统,无线局域网(WLAN,Wireless Local Area Networks)等。
还应理解,在本发明实施例中,发送端设备或接收端设备可以为电力通信系统的终端设备,终端设备可以经无线接入网(RAN,Radio Access Network)与一个或多个网络侧设备进行通信,该终端设备可包括电闸、传感器或智能电表。
还应理解,在本发明实施例中,发送端设备或接收端设备可以为电力通信系统的网络侧设备,网络侧设备可用于与终端设备通信,该网络设备可以是GSM系统或CDMA系统中的基站(BTS,Base Transceiver Station),也可以是WCDMA系统中的基站(Node B),还可以是LTE系统中的演进型基站(eNB,Evolutional Node B),或者该网络侧设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的基站设备等。
本发明实施例的电力通信系统中传输数据的方法、装置和设备可以使用至少两个频段进行无线通信,其中,该至少两个频段的频段授权情况相异,具体地说,该至少两个频段包括电力通信系统的专用授权频段(或称为“专用频段”)、非授权频段和非专用授权频段中的至少两个,也就是说,该至少两个频段可以包括专用授权频段和非授权频段,也可以包括专用授权频段和非专用授权频段,还可以包括非授权频段和非专用授权频段,还可以包括专用授权频段、非授权频段和非专用授权频段。
其中,电力通信系统的专用授权频段仅对电力行业授权,设备使用时无需申请授权或竞争信道,因此专用授权频段传输信息的能力相对可靠,能够传输对QoS要求较高或对可靠性要求较高的信息;非授权频段对所有 行业开放,且频段的带宽较大,设备使用时无需申请授权,但是该频段容易受到干扰,并且设备使用时需要竞争信道,适用于传输信息量大且对可靠性要求较低或对QoS要求较低的信息;非专用授权频段的带宽也比较大,可靠性也较高,设备使用该频段无需竞争信道,但是在不同的地方分配给了不同的行业使用,因此非专用授权频段适用于有可靠性要求,但只在局部区域,而不是全国范围内,进行传输的信息。
本发明实施例中的目标频段为电力通信系统从上述至少两个频段中确定要使用的频段。
图1是适用本发明实施例的电力通信系统中传输信息的方法的示意图。应注意,图1的例子仅仅是为了帮助本领域技术人员更好地理解本发明实施例,而非限制本发明实施例的范围。例如,在图1中,电闸130、传感器140、智能电表150都属于电力终端设备,转发设备120和电力控制中心110属于网络侧设备,图1分别描述了一个电闸、传感器、智能电表、转发设备和电力控制中心,但电力终端设备的数目和网络侧设备的数目还可以是其它的数目,本发明实施例对此不作限定,也就是说,本发明实施例可以只包括一个电力终端设备和一个网络侧设备,也可以包括一个电力终端设备和多个网络侧设备,还可以包括多个电力终端设备和一个网络侧设备,还可以包括多个电力终端设备和多个网络侧设备。
应理解,本发明实施例可以包括一种电力终端设备和一种网络侧设备,也可以包括一种电力终端设备和多种网络侧设备,还可以包括多种电力终端设备和一种网络侧设备,还可以包括多种电力终端设备和多种网络侧设备。
还应理解,电力终端设备可以通过不同频段向网络侧设备发送信息,也可以通过不同频段接收网络侧设备发送的信息。如图2所示,图2举例描述了一种可接收或发送信息的传感器200,该传感器200包括:敏感器件210、处理器220、存储器230、总线系统240和收发器250。其中,敏感器件210、处理器220、存储器230和收发器250通过总线系统240相连,敏感器件210直接感受被测量信息,例如温度信息,并将其转换成电信号,存储器230用于存储指令,处理器220用于执行存储器230存储的指令,以控制该收发器接收信号或发送信号。
在电力通信系统中,电闸属于控制类终端,电闸的断开和闭合都受系统发送的控制信息控制,传感器属于监测类终端,可以监测电线的温度、电流 强度等信息,智能电表记录的数据属于计量类信息,因此,电力通信系统中传输的信息可以包括控制类信息、监测类信息和计量类信息。
目前,某些国家的电力通信系统的可用频段包括:(1)专用授权频段(例如,230MHz频段):电力通信系统在该频段内有1MHz带宽的专用频段,但该1MHz带宽的专用频段并非连续的频谱,而是一系列离散的频点,需要采用特殊的频谱聚合技术来利用,如表1和表2所示,每个离散频点带宽为25kHz,总共40个频点,共1MHz带宽。该频段的优点是频率低、波长长,覆盖范围广。(2)非专用授权频段(例如,1.8GHz频段):整体公开给各个行业申请,而非电力通信系统专用。目前,该频段已在不同的城市应用到电力、机场、航运、铁路、公路、地铁中,该频段的优点是带宽大,带宽可达20MHz(1785MHz~1805MHz)。(3)非授权频段:例如,2.4GHz频段、5GHz频段,该频段的优点是带宽大,带宽可达80MHz,甚至160MHz,缺点是频段存在干扰,不可靠,信道共享,发送端设备不一定能竞争到信道,信息发送可能有延迟。

表2电力专用频点二
Figure PCTCN2016071444-appb-000002
具体而言,传感器采集到的监测类信息可以按照LTE-A(LTE-Advanced,长期演进技术升级版)的帧格式生成数据包,通过230MHz频段或1.8GHz频段发送给基站,也可以按照IEEE(Institute of Electrical and Electronics Engineers,电气和电子工程师协会)802.11ac标准中的帧格式生成数据包,通过2.4GHz频段和/或5GHz频段发送给接入点;智能电表采集到计量类信息后可以按照IEEE 802.11ac标准中的帧格式生成数据包,通过2.4GHz频段和/或5GHz频段发送给接入点,也可以按照LTE-A的帧格式生成数据包,通过1.8GHz频段发送给基站。
相应地,电闸可以通过230MHz频段接收基站发送的信息,传感器可以通过230MHz频段或1.8GHz频段接收基站发送的信息,也可以通过2.4GHz频段和/或5GHz频段接收接入点发送的信息,智能电表可以通过2.4GHz频段和/或5GHz频段接收接入点发送的信息,也可以通过1.8GHz频段接收基站发送的信息。
图3是本发明实施例提供的电力通信系统中传输信息的方法的示意性流程图。图3所示的方法可以由发送端设备执行,该发送端设备可以是图1中的电闸130、传感器140或智能电表150,也可以是电力控制中心110,还可以是转发设备120。如图3所示,该方法300包括:
S310,根据待发送信息的信息类型和该信息类型与频段之间的对应关系,从至少两个频段中确定目标频段;
S320,通过该目标频段发送该待发送信息。
在S310中,具体而言,发送端设备首先需要确定能够使用的频段,在获取待发送信息后,根据该待发送信息的信息类型确定发送该待发送信息的频段。在本发明实施例中,发送端设备可以是终端设备(即,情况1),也可以是网络侧设备(即,情况2),下面,分别对以上两种情况进行说明。
情况1
可选地,终端设备根据待发送信息的信息类型确定发送待发送信息的频段,包括:
如果待发送信息为监测类信息,终端设备可以确定通过通信系统的专用授权频段、非专用授权频段或非授权频段发送待发送信息,具体地说,电力通信系统确定当前可使用频段为230MHz频段和2.4GHz频段,传感器属于监测类终端设备,传感器采集到的电线温度的信息属于监测类信息,可以确定通过230MHz频段发送该信息,也可以确定通过2.4GHz频段发送该信息,还可以确定不发送该信息,可选地,如果电力通信系统还申请到了1.8GHz频段的使用权,还可以确定通过1.8GHz频段发送监测类信息。
如果该待发送信息为计量类信息,终端设备可以确定通过通信系统的非专用授权频段或非授权频段发送该待发送信息,具体地说,电力通信系统确定当前可使用频段为230MHz频段和2.4GHz频段,智能电表属于计量类终端设备,智能电表采集到的用户用电度数信息属于计量类信息,可以确定通过2.4GHz频段发送该信息,如果电力通信系统还申请到了1.8GHz频段的使用权,还可以确定通过1.8GHz频段发送用户用电度数信息。
相应地,接收端设备可以根据事先约定的规则在相应的频段检测信号,准备接收终端设备发送的信息。
应理解,上述实施例仅是举例说明,本发明实施例不限于此,比如传感器采集的信息还可以是电流强度的信息,上述列举出来的具体频段也仅为方 便理解,任何可以根据待发送信息的信息类型和该信息类型与频段之间的对应关系,从至少两个频段中确定目标频段的方法都属于本发明保护的范围。
情况2
可选地,网络侧设备根据待发送信息的信息类型确定发送该待发送信息的频段,包括:
当网络侧设备为电力通信网中的控制类设备时,可以向其它设备发送控制类信息,网络侧设备可以确定通过通信系统的专用授权频段发送该待发送信息,例如,当网络侧设备为电力通信系统的控制中心时,电力通信系统确定当前可使用频段为230MHz频段和2.4GHz频段,控制中心准备向电闸发送闭合开关的信息,该信息属于控制类信息,可以确定通过230MHz频段发送该信息,该信息可以由基站转发,也可以由数传电台发送。
此外,网络侧设备还可能是转发类设备,可以接收其它设备发送的信息,并将其转发给相应的设备。此时,网络侧设备可以根据接收到的信息的信息类型以及信息类型与频段的对应关系类来确定目标频段,具体地,可以是基站接收电力控制中心发送的命令智能电表上传用电度数的信息,该信息属于控制类信息,基站可以确定通过230MHz频段向智能电表发送该信息,也可以是接入点接收该信息,并确定通过2.4GHz频段转发该信息,还可以是基站或接入点接收传感器发送的电线温度或电流强度的信息,并通过230MHz频段或2.4GHz频段转发给控制中心。
相应地,接收端设备可以根据事先约定的规则在相应的频段检测信号,准备接收网络侧设备发送的信息。
在S320中,具体而言,发送端设备在确定待发送信息的目标频段后,根据目标频段所使用的网络类型生成相应格式的数据包,将待发送信息发送出去。
例如,如果发送端设备确定通过230MHz频段发送信息,可以按照LTE-A的帧格式生成数据包,也可以按照其它蜂窝网络的帧格式生成数据包,还可以按照数传电台的数据格式生成相应的数据包;如果终端设备确定通过2.4GHz频段发送信息,可以按照IEEE 802.11ac标准中的帧格式生成数据包,如果系统还申请到了1.8GHz频段的使用权,并且确定通过1.8GHz频段发送信息,可以按照LTE-A的帧格式生成数据包,也可以按照1.8GHz频段所支持的其它网络生成相应的数据包。
应理解,上述实施例仅仅是举例说明,本发明实施例不限于此,只要满足使用至少两个频段传输信息、并且能够使所选择的目标频段的频段授权情况与待发送信息的信息类型相适应的电力通信网络都属于本发明保护的范围。
因此,本发明实施例提出的电力通信系统中传输信息的方法,基于待发送信息的信息类型,从至少两个频段中确定目标频段,并通过该目标频段发送该待发送信息,可以使所选择的目标频段的频段授权情况与待发送信息的信息类型相适应,从而可以灵活应对不同信息类型的信息的传输要求,提高电力通信系统的性能。
可选地,从至少两个频段中确定目标频段时,还可以根据待发送信息的紧急程度来确定目标频段,方法300中从至少两个频段中确定目标频段,具体包括:
S311,根据待发送信息的信息类型和该信息类型与频段之间的对应关系,从至少两个频段中确定候选目标频段;
S312,根据待发送信息的紧急程度,从候选目标频段中确定一个目标频段。
例如,电力通信系统确定电力传感器采集到的信息为监测类信息,从而可以确定专用授权频段、非专用授权频段和非授权频段中的至少两个为候选目标频段,如果电力传感器采集到电线温度与环境温度相同的信息,电力通信系统可以确定该信息属于紧急程度较低的信息,进而可以确定非授权频段为该信息的目标频段;如果电力传感器采集到电线温度比环境高5摄氏度的信息,可以确定该信息为紧急程度较高的信息,进而可以确定授权频段为该信息的目标频段。
再例如,电力通信系统确定电力控制中心发送的信息为控制类信息,从而可以确定专用授权频段和非专用授权频段为候选目标频段,如果电力控制中心向电闸发送断开电闸的信息,电力通信系统可以确定该信息属于紧急程度较高的信息,进而可以确定专用授权频段为该信息的目标频段;如果电力控制中心向智能电表发送上报用电度数的信息,电力通信系统可以确定该信息属于紧急程度较低的信息,进而可以确定非专用授权频段为该信息的目标频段。
应理解,上述实施例仅仅是举例说明,本发明实施例不限于此,只要满 足使用至少两个频段传输信息、并且能够使所选择的目标频段的频段授权情况与待发送信息的紧急程度相适应的电力通信网络都属于本发明保护的范围。
因此,本发明实施例提供的电力通信系统中传输信息的方法,可以根据待发送信息的紧急程度来确定目标频段,从而可以满足不同紧急程度的信息的传输需求,进而提高电力通信系统的性能。
可选地,方法300中电力通信系统使用的至少两个频段包括:专用授权频段、非专用授权频段以及非授权频段中的至少两个。
可选地,方法300中待传输信息的信息类型包括控制类型、监测类型或计量类型。
可选地,方法300中根据待发送信息的信息类型和该信息类型与频段之间的对应关系,从至少两个频段中确定目标频段,具体包括:
S313,如果待发送信息的信息类型为控制类型,则可以将专用授权频段确定为待发送信息的目标频段;
S314,如果待发送信息的信息类型为监测类型,则可以将专用授权频段、非授权频段或非专用授权频段确定为待发送信息的目标频段;
S315,如果待发送信息的信息类型为计量类型,则可以将非授权频段或非专用授权频段确定为待发送信息的目标频段。
具体而言,如果待发送信息是控制中心向电闸发送的信息,例如命令电闸断开的信息,则电力通信系统可以确定该信息为控制类信息,从而可以根据控制类信息对QoS或传输可靠性要求较高的需求和专用授权频段的可靠性较高的特征,确定专用授权频段为该信息的目标频段;如果待发送信息是电力传感器向控制中心发送的信息,例如电线温度信息,则电力通信系统可以确定该信息为监测类信息,从而可以根据监测类信息对QoS或传输可靠性一般的需求,根据具体情况确定专用授权频段、非授权频段或非专用授权频段为该信息的目标频段;如果待发送信息是智能电表向控制中心发送的信息,例如用户用电度数的信息,则电力通信系统可以确定该信息为计量类信息,从而可以根据计量类信息对QoS或传输可靠性要求较低且对带宽要求较大的需求,以及非授权频段或非专用授权频段的可靠性较低且带宽较大的特征,根据具体情况确定非授权频段或非专用授权频段为该信息的目标频段。
应理解,上述实施例仅仅是举例说明,本发明实施例不限于此,例如控 制类信息还可以是控制中心命令传感器改变监测周期的信息,任何满足在电力通信系统中,根据待发送信息的信息类型从与频段的传输特征之间的对应关系确定目标频段的方法,都属于本发明保护的范围。
可选地,方法300中,如果待发送信息的信息类型为监测类型,则将专用授权频段、非授权频段或非专用授权频段确定为待发送信息的目标频段,具体包括:
S316,如果待发送信息的信息类型为监测类型,且该待发送信息的紧急程度满足第一预设条件,则可以将非授权频段确定为该待发送信息的目标频段;
S317,如果待发送信息的信息类型为监测类型,且该待发送信息的紧急程度满足第二预设条件,则可以将非专用授权频段确定为该待发送信息的目标频段;
S318,如果待发送信息的信息类型为监测类型,且该待发送信息的紧急程度满足第三预设条件,则可以将专用授权频段确定为该待发送信息的目标频段;
其中,第三预设条件对应的紧急程度高于第一预设条件和第二预设条件对应的紧急程度。
由于待发送信息的信息内容可能不同,因此同一信息类型的待发送信息在电力通信系统中的紧急程度可能不同,可以根据预设的条件可以对信息的紧急程度进行判断。
例如,当监测类信息为电线温度相对于环境温度的差值时,预设的条件可以为:如果终端设备采集到的信息包括电线温度与环境温度的温差小于3摄氏度,则可以认为该信息的紧急程度较低,满足第一预设条件,可以确定传输可靠性较低的非授权频段为该信息的发送频段;如果终端设备采集到的信息包括电线温度与环境温度的温差大于3摄氏度小于5摄氏度,则可以认为该信息的紧急程度一般,满足第二预设条件,可以确定传输可靠性一般的非专用授权频段为该信息的发送频段;如果终端设备采集到的信息包括电线温度与环境温度的温差大于5摄氏度,则可以认为该信息的紧急程度较高,满足第三预设条件,可以确定传输可靠性较高的专用授权频段为该信息的发送频段。
应理解,上述实施例仅仅是举例说明,根据信息内容的不同或当前使用 的频段的不同,预设条件的判定方式也会不同,例如,终端设备采集到的信息为电流强度信息,可以根据电流强度的不同设定不同的预设条件,再例如,如果当前可以用频段只有230MHz频段和2.4GHz频段,则可以将预设条件划分两个等级,因此,本发明实施例不限于此,在电力通信系统中,任何可以根据预设条件确定待发送信息的目标频段的方法都属于本发明保护的范围。
因此,本发明实施例提供的电力通信系统中传输信息的方法,可以通过非授权频段发送紧急程度较低的监测类信息,可以通过非专用授权频段发送紧急程度一般的监测类信息,可以通过专用授权频段发送紧急程度较高的监测类信息,从而可以满足不同紧急程度的监测类信息的传输需求,进而提高电力通信系统的性能。
可选地,方法200中的专用授权频段为230MHz频段,非授权频段为2.4GHz频段或5GHz频段,非专用授权频段为1.8GHz频段。
因此,本发明实施例提出的电力通信系统中传输信息的方法,通过基于待发送信息的信息类型,从至少两个频段中确定目标频段,并通过该目标频段发送该待发送信息,能够使所选择的目标频段的频段授权情况与待发送信息的信息类型相适应,从而能够灵活应对不同信息类型的信息传输的要求,提高电力通信系统的性能。
图4是本发明实施例提供的电力通信系统中传输信息的方法的示意性流程图。图4所示的方法可以由发送端设备执行,该发送端设备可以是图1中的电闸130、传感器140或智能电表150,也可以是电力控制中心110,还可以是转发设备120。如图3所示,该方法400包括:
S410,根据待发送信息的紧急程度和该紧急程度与频段之间的对应关系,从至少两个频段中确定目标频段;
S420,通过该目标频段发送待发送信息。
例如,如果电力传感器采集到电线温度与环境温度相同的信息,电力通信系统可以确定该信息属于紧急程度较低的信息,进而可以确定非授权频段为该信息的目标频段;如果电力传感器采集到电线温度比环境高5摄氏度的信息,可以确定该信息为紧急程度较高的信息,进而可以确定授权频段为该信息的目标频段。
再例如,如果电力控制中心向电闸发送断开电闸的信息,电力通信系统 可以确定该信息属于紧急程度较高的信息,进而可以确定专用授权频段为该信息的目标频段;如果电力控制中心向智能电表发送上报用电度数的信息,电力通信系统可以确定该信息属于紧急程度较低的信息,进而可以确定非专用授权频段为该信息的目标频段。
应理解,上述实施例仅仅是举例说明,本发明实施例不限于此,只要满足使用至少两个频段传输信息、并且能够使所选择的目标频段的频段授权情况与待发送信息的紧急程度相适应的电力通信网络都属于本发明保护的范围。
因此,本发明实施例提供的电力通信系统中传输信息的方法,可以根据待发送信息的紧急程度来确定目标频段,从而可以满足不同紧急程度的信息的传输需求,进而提高电力通信系统的性能。
可选地,方法400中电力通信系统使用的至少两个频段包括:专用授权频段、非专用授权频段以及非授权频段中的至少两个。
可选地,方法400中,根据待发送信息的紧急程度和该紧急程度与频段之间的对应关系,从至少两个频段中确定目标频段具体包括:
S411,如果待发送信息的紧急程度满足第一预设条件,则将非授权频段确定为待发送信息的目标频段;
S412,如果待发送信息的紧急程度满足第二预设条件,则将非专用授权频段确定为待发送信息的目标频段;
S413,如果待发送信息的紧急程度满足第三预设条件,则将专用授权频段确定为待发送信息的目标频段;
其中,第三预设条件对应的紧急程度高于第一预设条件和第二预设条件对应的紧急程度。
由于待发送信息的信息内容可能不同,因此待发送信息在电力通信系统中的紧急程度可能不同,可以根据预设的条件可以对待发送信息的紧急程度进行判断。
例如,当待发送信息为电线温度相对于环境温度的差值时,预设的条件可以为:如果终端设备采集到的信息包括电线温度与环境温度的温差小于3摄氏度,则可以认为该信息的紧急程度较低,满足第一预设条件,可以确定传输可靠性较低的非授权频段为该信息的发送频段;如果终端设备采集到的信息包括电线温度与环境温度的温差大于3摄氏度小于5摄氏度,则可以认 为该信息的紧急程度一般,满足第二预设条件,可以确定传输可靠性一般的非专用授权频段为该信息的发送频段;如果终端设备采集到的信息包括电线温度与环境温度的温差大于5摄氏度,则可以认为该信息的紧急程度较高,满足第三预设条件,可以确定传输可靠性较高的专用授权频段为该信息的发送频段。
应理解,上述实施例仅仅是举例说明,根据信息内容的不同或当前使用的频段的不同,预设条件的判定方式也会不同,例如,终端设备采集到的信息为电流强度信息,可以根据电流强度的不同设定不同的预设条件,再例如,如果当前可以用频段只有230MHz频段和2.4GHz频段,则可以将预设条件划分两个等级,因此,本发明实施例不限于此,在电力通信系统中,任何可以根据预设条件确定待发送信息的目标频段的方法都属于本发明保护的范围。
因此,本发明实施例提供的电力通信系统中传输信息的方法,可以通过非授权频段发送紧急程度较低的信息,可以通过非专用授权频段发送紧急程度一般的信息,可以通过专用授权频段发送紧急程度较高的信息,从而可以满足不同紧急程度的信息的传输需求,进而提高电力通信系统的性能。
可选地,方法400中的专用授权频段为230MHz频段,非授权频段为2.4GHz频段或5GHz频段,非专用授权频段为1.8GHz频段。
因此,本发明实施例提出的电力通信系统中传输信息的方法,通过基于待发送信息的紧急程度和该紧急程度与频段之间的对应关系,从至少两个频段中确定目标频段,并通过该目标频段发送该待发送信息,能够使所选择的目标频段的频段授权情况与待发送信息的紧急程度相适应,从而能够灵活应对不同信息类型的信息传输的要求,提高电力通信系统的性能。
