本技术涉及一种电网无线数据监控仪。
技术介绍
在实际生产、生活过程中,各电业局需对其管辖内的企、事业单位、居民的用电情况进行实时监控和管理。目前,各电业局实时监控和管理的方式主要有两种一种是人工管理方式,即各电业局定期派人上门进行数据的抄表、统计、上报。这种管理方式的缺点是耗费大量的人力、物力、财力,生产效率低,管理水平落后,运营成本高;而且容易造成错抄、漏抄或人情电等现象。另一种可以概括为非人工管理模式。它主要包括以下四种类型1、通过一些测量仪器实时采集各变电所、重要用户台区的变压器数据,然后通过有线方式、数字微波方式、电力载波方式或集群方式将数据传送至生产调度中心。2、通过低压载波方式自动抄送用户电表数,然后通过有线方式将数据传至监控中心。3、通过单独的电网GIS地理信息系统,实现对电网的网络结构参数、重要性能指标、档案信息等的管理。4、通过单独的电费缴费系统、查询系统,对各区域的电费进行管理。以上这四种方式在技术上是成熟的,但是在数据传输、通信方式上存在以下问题1、通过有线方式传输数据,在市区内布线难度大,运行中的线路维护困难,系统建设周期长,可靠性、稳定性差,抗干扰能力不好,网络覆盖范围有限。2、采用数字微波方式只适用于点与点之间的局部通信,且数据定向传输,由于其直线传输的特点,不适用于地域分散的监控情况。3、集群方式用户首先需申请一个专用频点,并自建一个覆盖一定范围的基站,通过基站接收终端传来的实时数据,再传输至监控中心。这种方式网络覆盖范围小,监控范围受到网络范围的限制,用户需自建通信网络,经济投入大,维护量大,不具备可扩展性且保密性差。4、 ...
