Description

一种基于NB-Iot网络的物联网表用户停复电判断方法
技术领域
本发明涉及计算机网络技术及电力供配电技术领域，特别涉及一种基于NB-Iot网络的物联网表用户停复电判断方法。
背景技术
在现有非物联网电表数据采集情况下，电网采集系统只能通过终端上报的停复电告警信息进行停复电判断，而这种通过终端获取停复电事件信息的方法，只能感知用户所属台区是否停复电，而单个用户的停复电情况无法及时准确感知，因此当用户停电时或复电不及时时会出现投诉等情况，造成电网公司满意度下降，而在NB-Iot物联网表环境下，采集系统可以直接与用户使用的物联网表进行数据交互，物联网表通过加装电池、超级电容的方式对用户停电时对电表进行持续供电，从而可以将停复电事件信息及时上报告采集系统，采集系统就可以从过去的只能感知台区停复电向感知用户是否停复电进行转变。
发明内容
有鉴于此，本发明的目的是提供一种基于NB-Iot网络的物联网表用户停复电判断方法。通过在采集系统中建立与物联网表停复电事件交互进行用户停电的判断。
本发明的目的是通过以下技术方案实现的：
一种基于NB-Iot网络的物联网表用户停复电判断方法，其特征在于：通过采集系统与物联网表建立用户用电数据交互，解决现有的只能通过电力终端感知台区停复电无法感知用户停复电的情况。
其中，所述用户停复电判断方法，是指采集系统获取物联网表的停复电事件信息，由采集系统根据停复电事件信息对用户是否停复电进行判断。
进一步，所述采集系统获取物联网表上报的停电事件进行停电判断、获取物联网表上报的复电事件进行复电判断。
进一步，其中，所述停电事件判断是采集系统根据物联网表上送的主站停电规约进行用户是否停电判断，确认是停电告警信息后，在系统中提示该用户已停电。
进一步，通过确定是停电告警信息的，结合掉电信息最近15分钟内该电表的电压、电流示值曲线，判断该用户停电的真实性。
进一步，如果用户电表最近一段时间内电压、电流示值曲线正常，则判断该用户停电无效，反之如果用户电表最近一段时间内电压、电流示值停止变动，则结合停电告警信息判断该用户停电有效。
进一步，所述复电事件判断是采集系统根据物联网表上送的主站复电规约进行用户是否复电判断，确认是复电告警信息后，在系统中提示该用户已复电。
进一步，通过确定是复电告警信息的，结合复电信息最近15分钟内该电表的电压、电流示值曲线，判断该用户停电的真实性；
进一步，如果用户电表最近一段时间内电压、电流示值曲线依然停止变动，则判断该用户复电无效，反之如果用户电表最近一段时间内电压、电流示值开始变动，则结合复电告警信息判断该用户复电有效。
本发明的有益效果是：本发明有利于将过去的只能感知到台区停复电转变为及时感知用户停复电，降低了用户停电或未及时复电后带来的用户投诉，实现了电网对用户用电情况的及时感知，辅助客服在用户停电后及时感知并提前发布消息，有效提升了用户对电网服务的满意度。
本发明的其他优点、目标和特征在某种程度上将在随后的说明书中进行阐述，并且在某种程度上，基于对下文的考察研究对本领域技术人员而言将是显而易见的，或者可以从本发明的实践中得到教导。本发明的目标和其他优点可以通过下面的说明书和前述的权利要求书来实现和获得。
附图说明
为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步的详细描述，其中：
图1为停电判断方法图；
图2为复电判断方法图。
具体实施方式
以下将参照附图，对本发明的优选实施例进行详细的描述。应当理解，优选实施例仅为了说明本发明，而不是为了限制本发明的保护范围。
窄带物联网(Narrow Band Internet of Things,NB-IoT)已经成为万物互联网络的一个重要分支。NB-IoT构建于蜂窝网络，只消耗大约180kHz的带宽，可直接部署于GSM网络、UMTS网络或LTE网络，以降低部署成本、实现平滑升级。
NB-IoT是IoT领域一个新兴的技术，支持低功耗设备在广域网的蜂窝数据连接，也被叫作低功耗广域网(LPWAN)。NB-IoT支持待机时间长、对网络连接要求较高设备的高效连接。据说NB-IoT设备电池寿命可以提高至少10年，同时还能提供非常全面的室内蜂窝数据连接覆盖。
本发明的一种基于NB-Iot网络的物联网表用户停复电判断方法，是通过采集系统与物联网表建立用户用电数据交互，实现对用户停复电的情况判断；
其中，用户停复电的判断方法，是指采集系统获取物联网表的停复电事件信息，由采集系统根据停复电事件信息对用户是否停复电进行判断。具体是采集系统获取物联网表上报的停电事件进行停电判断、获取物联网表上报的复电事件进行复电判断。
如图所示，其中，在停电判断方法中，采集系统的具体分工如下：
1：采集系统根据物联网表上送的主站停电规约(本实施例采用南网2013规约停电告警编码E2000033)进行用户是否停电判断；
2：是停电告警则初步确定该用户停电。
3：通过确定是停电告警信息的，结合掉电信息最近15分钟内该电表的电压、电流示值曲线，判断该用户停电的真实性；
4：如果用户电表最近一段时间内电压、电流示值曲线正常，则判断该用户停电无效，反之如果用户电表最近一段时间内电压、电流示值停止变动，则结合停电告警信息判断该用户停电有效。该时间段的选择区间为10-30分钟，本实施例中以15分钟为宜。
在复电判断方法中，采集系统的具体分工如下：
1：采集系统根据物联网表上送的主站复电规约(本实施例中采用的是南网2013规约复电告警编码E2000034)进行用户是否复电判断，
2：是复电告警则初步确定该用户停电。
3：通过确定是复电告警信息的，结合复电信息最近时间段内该电表的电压、电流示值曲线，判断该用户停电的真实性；
4：如果用户电表最近一段时间内电压、电流示值曲线依然停止变动，则判断该用户复电无效，反之如果用户电表最近一段时间内电压、电流示值开始变动，则结合复电告警信息判断该用户复电有效。该时间段的选择区间为10-30分钟，本实施例中以15分钟为宜。
最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本技术方案的宗旨和范围，其均应涵盖在本发明的权利要求范围当中。
