Description

说 明 书 用电信息采集系统现场测试仪及其测试方法 技术领域
本发明涉及一种测试仪及测试方法,尤其是一种用于电力系统中的用电信息采集系统现 场测试仪及其测试方法。
背景技术
随着计算机技术和通信技术的发展, 在供电系统中已经不再采用传统的人工抄表方法, 取而代之的是智能化的远程抄表系统。 抄表系统包括智能电表、 采集器和集中器。 在住宅楼 的表箱内,安装有一个采集器和多个智能电表。所有电表都通过 RS485总线与采集器相连接, 由采集器采集所有电表上的数据, 工作人员只需将数据采集装置连接在采集器上, 就可以在 现场获得表箱内的所有电表的数据。某一区域内的所有采集器都可以通过有线通信网络或无 线通信网络与集中器相连接, 并可将数据发送至集中器上, 由集中器汇集区域内的所有电表 数据并进行分析处理。集中器可通过通信网络将指令发送给采集器, 由采集器完成相关的数 据采集工作并将数据传送给集中器, 实现远程抄表的功能。每个智能电表都具有一个唯一的 ID号, 该 ID号被输入至采集器和集中器中, 采集器和集中器根据 ID号来识别不同的电表。 设备安装结束后,由工作人员将 ID号记录下来,然后再回到单位将 ID号输入智能抄表系统, ID号一般为 10位数字, 工作量大而且繁琐, 人工抄写和输入的方式很容易出错。
在现场安装表箱时, 大量的智能电表和釆集器需要安装到用户现场。 为确认电表和采集 器之间有效连接, 通常在现场安装后进行测试。 在一个城市内, 智能电表的个数有几十万乃 至几百万, 采集器的个数也高达数十万。 由于电表数量众多, 调试和测试工作量非常大。 现 场采集器与智能电表的通信测试、集中器和采集器的载波通信、集中器的参数设置等工作非 常重要, 是保证用电信息采集系统正常运转的基础性工作, 是保证系统能够正常运行的基本 条件。 目前在施工过程中, 还没有能够对智能电表、 釆集器和集中器等设备进行调试和测试 的智能化仪器。 目前, 电表采集终端安装和调试以及核对均为独立的环节。 当发现集中器无 法抄到数据时, 无法辨别是载波问题、 采集设备问题还是 ^装问题, 工作人员只能逐一检测 各个工作环节, 对电表、 采集器和集中器分别进行检测, 故障诊断的工作非常复杂, 同时返 工的工作量很大, 解决问题的工作效率较低, 因而就迫切需要一种能够在表箱的采集器和电 表安装完成后立即测试的装置, 以提高智能抄表系统的测试效率。
另外, 采集系统使用后, 为确保电表的准确计量, 还需要工作人员定期到现场核对电表 的读数。现有的方式是工作人员先从集中器获取大量电表的读数, 然后到现场逐一核对。 由 于电表数量多, 从集中器获取电表读数的时间和现场读取电表的时间存在时间差, 两个读数 确认本 之间也存在差异。 如果两个读数相差不大, 工作人员就认为电表正常。 只有在两个读数相差 较大的时候, 才认为电表存在故障。 如此一来, 如果电表存在误差而且误差不大, 电表故障 就无法检测出来, 会影响抄表系统的准确性。

本发明的测试仪, 采用高效 ARM处理器作为微处理器, 具有超高速处理数据、 FLASH容 量随需而定、 突破擦写寿命限制和保证了数据的完成性和连续性等优点。
本发明的测试仪, 可以在现场高效地对采集器和智能电表的连接状态进行测试, 测试方 便快捷, 能及时发现智能抄表系统的故障; 在电表校核时, 在现场读取数据时就能核对电表 的读数, 避免了两个读数之间出现时间差而导致校核时无法获知电表的微小误差的问题。 本发明的测试仪, 以 ARM处理器为高效内核, 通过 ARM内置的数据分析处理程序, 对获 得的测试数据进行分析和处理,从而为工作人员分析智能抄表系统的故障位置和故障原因提 供了有效的数据来源, 能够直观的反应采集设备、 安装工艺以及核对出计量表计的准确性, 以期简化工作流程, 提高工作效率降低电网运行的人力成本并保证电力客户的正常供电。
