为了解决在对抄表系统中的设备进行宽带升级时存在的升级成本高、升级难的问题，本申请实施例提供了一种抄表方法、装置及系统。
以下结合说明书附图对本申请的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本申请，并不用于限定本申请，并且在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
目前，抄表系统中的窄带载波集中器和窄带载波电能表之间使用窄带载波信号进行通信，考虑到窄带载波信号的传输距离较远，为了降低升级成本，可以不对窄带载波电能表进行升级，而窄带载波集中器一般还需兼具对各窄带载波电能表在一定时间段内的电量信息进行汇总处理的功能，数据处理量和数据传输量都比较大，因此，有必要对窄带载波集中器进行升级，以满足 主站对获取的电量信息的实时性要求，但此时，抄表系统中就同时出现了支持宽带载波通信的宽带载波集中器和支持窄带载波通信的窄带载波电能表，由于宽带载波和窄带载波的频段不同，宽带载波集中器和窄带载波电能表之间并不能进行通信。
为了解决这个问题，发明人想到在两者中间加入双模通信模块，利用双模通信模块实现宽带载波集中器发送的宽带载波信号与窄带载波电能表发送的窄带载波信号之间的相互转换，具体地，当宽带载波集中器需要向窄带载波电能表发送消息时，可将消息承载在宽带载波信号中发送给双模通信模块，双模通信模块负责将承载消息的宽带载波信号转换为窄带载波信号，然后，将承载消息的窄带载波信号发送给窄带载波电能表；当窄带载波电能表需要向宽带载波集中器发送消息时，可将消息承载在窄带载波信号中发送给双模通信模块，双模通信模块负责将承载消息的窄带载波信号转换为宽带载波信号，然后，再将承载消息的宽带载波信号发送给宽带载波集中器，这样，即可很好地解决两者之间的通信问题。
另外，窄带载波信号的传输距离比较远，但稳定性比较差，因此，在具体实施时，可能还会出现有些窄带载波电能表的电量信息无法读取的情况，为了解决该问题，可以将这些窄带载波电能表升级为宽带载波电能表，利用宽带载波电能表读取电能表的电量信息，因为需要升级的窄带载波电能表的数量也不会太大，所以升级成本也不会太高。
具体地，参见图2，图2示出了本申请实施例提供一种抄表系统的示意图，包括，宽带载波集中器、与宽带载波集中器相连的双模通信模块和至少一个宽带载波电能表，其中，宽带载波集中器可与上游的主站相连，双模通信模块可与下游的至少一个窄带载波电能表相连。
当满足抄表条件时，宽带载波集中器可向双模通信模块和宽带载波电能表同时发送承载有抄表指令的第一宽带载波信，对窄带载波电能表和宽带载波电能表进行抄表。
在具体实施时，当双模通信模块接收到第一宽带载波信号后，可对第一 宽带载波信号进行调制解调得到第一窄带载波信号，进而将第一窄带载波信号发送给与自身相连的各个窄带载波电能表，每个窄带载波电能表可根据第一窄带载波信号中承载的抄表指令读取自身的电量信息，并可将读取到的电量信息承载在第二窄带载波信号中发送给双模通信模块，双模通信模块还可对每个窄带载波电能表发送的第二窄带载波信号进行调制解调得到第二宽带载波信号，进而将第二宽带载波信号发送给宽带载波集中器，宽带载波集中器接收到第二宽带载波信号后，可存储第二宽带载波信号中承载的电量信息。
当宽带载波电能表接收到第一宽带载波信号后，可读取自身的电量信息，并将读取到的电量信息承载在第三窄带载波信号中发送给宽带载波集中器，宽带载波集中器接收到第三宽带载波信号后，可存储第三宽带载波信号中承载的电量信息。
此外，在具体实施时，宽带载波集中器在存储宽带载波信号中承载的电量信息之后，还可对存储的电量信息进行分析汇总，进一步地，在满足预设的上报条件时，将分析汇总数据承载在第四宽带载波信号中上报给主站。
参见图3，为本申请实施例提供的又一种抄表系统的示意图，包括宽带载波集中器、与宽带载波集中器均相连的宽带载波电能表和双模通信模块，以及与双模通信模块相连的窄带载波电能表，其中，宽带载波集中器包括集中器和集中器宽带模块；宽带载波电能表包括电能表和电能表宽带模块，窄带载波电能表包括电能表和电能表窄带模块。
在具体实施时，集中器与集中器宽带模块之间遵循《Q/GDW 1376.2—2013国家电网公司电力用户用电信息采集系统通信协议第2部分宽带载波集中器本地通信模块接口协议》，简称为国网376.2规约，或者遵循《广东电网有限责任公司计量自动化终端本地通信模块接口协议(2016版)》，简称为南网16规约；电能表与电能表宽带模块或电能表窄带模块之间遵循《DL/T 645—2007多功能电能表通信协议》，简称为645规约，其余模块之间遵循电力线载波协议。
下面对抄表过程进行介绍：
集中器发起抄表任务，通过376.2规约传输给集中器宽带模块，集中器宽带模块将抄表报文通过电力线宽带载波协议发送给电能表宽带模块和双模通信模块。
电能表宽带模块截取抄表报文中的645规约报文，通过645规约将截取的报文发送给电能表，电能表执行抄表指令，电能表在抄到电量数据后，通过645规约传输给电能表宽带模块，由电能表宽带模块再通过电力线宽带载波协议传输给集中器宽带载波模块，集中器宽带载波模块通过376.2规约传输给集中器。
双模通信模块将承载抄表报文的宽带载波信号转换为窄带载波信号，然后将窄带载波信号发送给电能表窄带模块，电能表窄带模块将抄表报文通过645规约传输给电能表，电能表执行相应的指令，电能表抄到电量数据后，通过645规约传输给电能表窄带模块，电能表窄带模块通过电力线宽带载波协议将电量信息再传输给双模通信模块，双模通信模块将承载电量信息的窄带载波信号转换为宽带载波信号，然后将宽带载波信号发送给集中器宽带模块，集中器宽带载波模块通过376.2规约传输给集中器。
在具体实施时，集中器还可对抄到的电量信息进行分析汇总，等待主站的抄录。
