[0008] 作为优选, 在用户界面装置与表计时钟一致后, 所述用户界面装置抄读表计的表计 电量数据, 并将所述表计电量数据进行编码以整合至表计注销请求信息表中。
[0009] 作为优选, 所述表计电量数据包括当前电量数据和历史电量数据, 所述当前电量数 据由当前电量、 当前最大需量和当前瞬时量组成, 所述历史电量数据由历史电量、 时段最大 需量和累计最大需量组成。

[0012]作为优选, 此方法的数据传输和对功能的实现皆是通过数据加密来实现的。
[0013J 令牌(TOKEN)是一种特殊的帧, 用于控制网络结点的发送权, 只有持有 TOKEN 的结点才能发送数据, 由于发送结点在获得发送权后就会将 TOKEN删除, 在一个网络环路 上不会再有 TOKEN出现, 其他结点也不可能再得到 TOKEN, 保证环路上某一时刻只有一 个结点发送数据, 因此是一种无争用型介质访问方式, TOKEN有 "忙"和 "闲"两种状 态。 当网络环路正常工作时, 单向逐结点传送数据。
[0014] 当某一个节点要发送数据时, 需要等待空闲 TOKEN的到来, 获得空 TOKEN后, 将 其置为 "忙", 并以帧为单位发送数据, 如果下一节点为目的结点, 则将帧复制到设备缓冲 区, 在帧中标志出帧已被正确接收和复制, 同时将帧送回环上, 帧绕行一周后到达源结点 上, 源结点回收已发送的帧, 并将 TOKEN置为 "闲"状态, 再将 TOKEN 向下个结点发 送。
[0015] 本发明的表计自动注销方法又是通过一种预付费售电系统来实现的, 所述预付费售 电系统包括用户界面装置、 终端服务器、 电表和远端存储模块, 其中用户界面装置包括数据 处理模块、 输入模块、 输出模块、 显示模块和本地存储模块。 输入模块用于用户对界面装置 的操作输入, 显示模块用于显示轮显项目, 数据处理模块分别通讯连接至输入模块、 输出模 块、 显示模块和本地存储模块, 输出模块分别与终端服务器和电表通讯连接, 以抄读电表电 量数据并与所述终端服务器进行双向数据通讯, 终端服务器与远端存储模块通讯连接以迸行 数据存取。

具体实施方式
[0019] 以下将参照附图以详尽描述本发明的优选实施方式。 图 1 示意性描述了本发明预付 费售电系统的表计注销方法的第一优选实施例流程图, 该方法是通过图 2中示意性绘示的预 付费售电系统来实现的, 如图 2所示, 用户界面装置 10包括数据处理模块 11、 输入模块 12、 输出模块 13、 显示模块 14和本地存储模块 15。 在步骤 101中, 用户通过输入模块 12 输入注销该用户电表的请求并输入用户信息。 图 3 绘示了一种优选用户输入界面, 其中 "EDIT"表示可由用户自行输入的项目, 虚线方框 1010中为必须输入的项目。 用户界面装 置 10通过输出模块 13向终端服务器 20发送电表注销请求信息表, 此信息表包括表计厂商 信息表、 表计状态 /型号信息表, 这些信息表可以 "BASIC"作为前缀, 举例而言, 厂商信 息表 BASIC— MANUFACTURER包含 MANUFACTURER— ID、 MANUFACTURER— CODE、 CREATORJD 等信息, 表计状态 /型号信息表 BASIC— METER— TYPE 包含有 METER— MODEL_ID、 MANUFACTURER^ , CREATOR— ID。 TARIFF— UM等信息, 在 这两个信息表中, MANUFACTURER— ID和 METER— MODEL— ID信息起关键作用, 其中 BASIC_MANUFACTURER 信 息 表 与 BASIC— METER_TYPE 信 息 表 是 通 过 MANUFACTURER— ID和 CREATOR— ID来连接的。 电表注销请求信息表是数据处理模块 11 根据图 3所示的用户注销电表请求, 通过读取本地存储模块 15中的数据而自动生成。
[0020]在步骤 102 中, 当用户输入完成后, 选择图 3 中所示的 "销户"控键, 则用户界面 装置 10生成信息表并发送至终端服务器 20, 所述终端服务器 20接收电表注销请求信息 表, 并进行用户 /表计档案表査询。 用户 /表计档案表是设置于远端存储模块 40中, 其包括表 计档案表和用户档案表, 表计档案表和用户档案表可以 " INFO"作为前缀命名, 举例而 言, 表计档案表 INFO— METER包含有 METER— MODEL— ID、 METER— ADDR、 STATUS, SGCJD、 USER— ACCOUNTS ZONE— TYPE— ID和 REGION_TYPE— ID等信息, 用户档案表 INFO— USER 包含有 USER—ACCOUNT、 USER— ADDR、 METER— ADDR、 STATUS , USER— ID等。 其中, 当表计和用户进行信息关联时, 需要将 USER— ACCOUNT进行对应, 同时需要将 INFO_METER档案表的 METER— MODELJD与 BASIC— METER— TYPE信息表 的 METER_MODELJD相对应。
[0021]在步骤 103中, 若所述电表注销请求信息表中的这些信息符合远端存储模块 40中预 存的用户信息, 则所述终端服务器 20受理电表注销请求并反馈等待确认信息表, 若所述电 表注销请求信息表不符合终端服务器的用户 /表计档案数据, 则所述终端服务器 20反馈给用 户界面装置 10错误信息码, 例如返回值定义为 0, 代表信息符合, 即操作成功; 返回值为 1 则失败; 返回值为 8, 则代表用户输入参数不完整或格式错误。 用户界面装置 10识别这些 信息码, 并读取本地存储模块 15 中对应的数据信息, 生成用户操作提示信息, 以指导用户 的输入操作。
[0022]在步骤 104中, 用户界面装置 10接收等待确认信息表, 经用户确认后将确认信息表 发送至终端服务器 20。
{00231 图 4给出了终端服务器 20的一个操作界面的实施例示意图, 如上所述, 若信息符 合, 则终端服务器 20上生成如图所示的界面, 其中方框 1020 中是一个用户的若干信息项 目, 此界面也可以对多个用户同时操作。 当选中一个用户 1020时(本发明的系统确保 "用 户已装电表数"一栏不为 0), 界面即出现图 4中下方的表格栏 1040, 如图所示, 用户的表 计信息项包括例如表号、 表型、 厂商、 SGC、 Ή名称、 拆 /装表日期等, 这些信息项是分别 通过用户 /表计档案表的信息加以识别的, 终端服务器 20将这些信息项进行数据整合。
[0024]在步骤 105中, 终端服务器 20接收确认信息表, 选择虚线方框 1030中所示的 "销 户"控键, 生成注销请求记录并将其存储至远端存储模块 40, 随后反馈用户一系列 DM— TOKEN信息表。
[0025]在步骤 106中, 用户界面装置 10向电表 30录入 DM_TOKEN信息表, 所述电表读取 这些 DM— TOKEN信息表后, 反馈一系列 RC— TOKEN信息表。
[0026]在步骤 107中, 用户界面装置 10读取电表返回的 RC— TOKEN表, 控制电表继电器 跳闸, 并向所述终端服务器发送一系列 MCJTOKEN信息表。
[0027J在步骤 108中, 终端服务器 20录入所述 MC— TOKEN信息表, 并确认是否存在用户 余额。
【00281在步骤 109中, 若确认存在余额, 则所述终端服务器将所述 MCJTOKEN信息表进行 解码并计算出应退还余额, 生成注销完成记录并将其存储至远端存储模块 40, 若确认不存 在余额, 则直接生成注销完成记录并将其存储至远端存储模块 40。
[0029] 在上述步骤中, 数据 (例如信息表) 的传输和功能实现都是通过数据加密来实现 的。 密钥数据可以 "KEY"作为前缀命名, 例如设定 SG 加密因子、 Ή加密因子、 费率索 引加密因子、 费率版本加密因子和终端服务器 20端需要的加密设备因子, 对于用户而言, 某些信息表利用这些加密因子使信息表对用户不可修改, 例如费率等信息是需要电力公司来 设定的。 而且在传输过程中, 数据不被第三方获得, 以保障数据的安全性和完整性。 [0030]在步骤 101 中, 在用户界面装置发送电表注销请求信息表时, 所述用户界面装置 10 与电表 30对应以对应时钟是否一致, 若一致则发送电表注销请求信息表, 若不一致则进行 自身时钟校准以保证时钟一致, 随后发送电表注销请求信息表。
[0031]作为优选, 在用户界面装置 10与表计 30时钟一致后, 所述用户界面装置 10抄读表 计 30的表计电量数据, 并将所述表计电量数据进行编码以整合至表计注销请求信息表中。
[0032] 作为优选, 表计电量数据包括当前电量数据和历史电量数据, 所述当前电量数据由 当前电量、 当前最大需量和当前瞬时量组成, 所述历史电量数据由历史电量、 时段最大需量 和累计最大需量组成。
[0033]在步骤 107中, 用户界面装置 10将 RQ_ TOKEN表进行解码, 获得电表继电器 /辅助 继电器状态信息表、 继电器控制模式信息表和超负荷阈值信息表并进行数据处理, 随后提取 所述继电器控制信息并发送至电表, 以控制电表 30的继电器跳闸。
[0034]在步骤 109中, 在将 MCJTOKEN表进行解码后, 所述终端服务器 20获得结算命令 并从远端存储模块 40 中提取表计档案表和用户档案表, 并根据所述表计电量数据计算出应 退还余额。
[0035]本发明第一实施例是通过一种预付费售电系统来实现的, 其包括用户界面装置 10、 终端服务器 20、 电表 30和远端存储模块 40, 其中用户界面装置 10包括数据处理模块 11、 输入模块 12、 输出模块 13、 显示模块 14和本地存储模块 15。 输入模块 12用于用户对界面 装置 10的操作输入, 显示模块用于显示轮显项目, 数据处理模块 11分别通讯连接至输入模 块 12、 输出模块 13、 显示模块 14和本地存储模块 15, 输出模块 13分别与终端服务器 20 和电表 30通讯连接, 以抄读电表 30的电量数据并与所述终端服务器 20进行双向数据通 讯, 终端服务器 20与远端存储模块 40通讯连接以进行数据存取。
[0036]作为优选, 输出模块包括 GPRS通讯模块、 PSTN模块、 ZigBee通讯模块、 RF模块 和 PLC模块。
[0037]作为优选, 通讯设置参数包括 GPRS参数、 PSTN参数、 ZigBee地址参数、 RF地址 参数和 PLC模块地址参数, 分别用以提供所述用户界面装置对 GPRS通讯模块、 PSTN模 块、 ZigBee通讯模块、 RF模块和 PLC模块的通讯控制。
[0038] 作为一种优选实施方式, 电表注销请求信息表中可包含用户状态信息表, 而此用户 状态信息表在步骤 102中被终端服务器 20接收, 终端服务器会査询此用户是否 (例如)在 使用表计的过程中存在窃电行为, 而这个方式可通过本发明所用的信息产生和传输方式加以 实现。 10039] 本发明的表计注销方法的另一实施例, 即用于用户需要更换电表时, 首先需要拆 表, 然后再装上新表, 这个操作同样需要使用本发明的表计注销方法, 以便历史数据完整正 确和电表的合理管理。
[0040]按照步骤 102, 当用户输入完成后, 选择图 3中所示的 "销户"控键, 则用户界面装 置 10生成信息表并发送至终端服务器 20, 所述终端服务器 20接收电表注销请求信息表, 并迸行用户 /表计档案表査询。 用户 /表计档案表是设置于远端存储模块 40中, 其包括表计档 案表和用户档案表, 表计档案表和用户档案表可以 " INFO"作为前缀命名, 举例而言, 表 计档案表 INFO— METER 包含有 METER_MODELJD、 METER—ADDR、 STATUS . SGC_ID、 USER— ACCOUNTS ZONE— TYPE— ID和 REGION— TYPE—ID等信息, 用户档案表 INFO— USER 包含有 USER—ACCOUNT、 USER— ADDR、 METER— ADDR、 STATUS . USER— ID等。 其中, 当表计和用户进行信息关联时, 需要将 USER— ACCOUNT迸行对应, 同时需要将 INFO— METER档案表的 METER— MODELJD与 BASIC— METER— TYPE信息表 的 METER_MODELJD相对应。
【0041〗按照步骤 103, 若所述电表注销请求信息表中的这些信息符合远端存储模块 40 中预 存的用户信息, 则所述终端服务器 20受理电表注销请求并反馈等待确认信息表, 若所述电 表注销请求信息表不符合终端服务器的用户 /表计档案数据, 则所述终端服务器 20反馈给用 户界面装置 10错误信息码, 例如返回值定义为 0, 代表信息符合, 即操作成功; 返回值为 1 则失败; 返回值为 8, 则代表用户输入参数不完整或格式错误。 用户界面装置 10识别这些 信息码, 并读取本地存储模块 15 中对应的数据信息, 生成用户操作提示信息, 以指导用户 的输入操作。
[0042]按照步骤 104, 用户界面装置 10接收等待确认信息表, 经用户确认后将确认信息表 发送至终端服务器 20, 确认信息表中包含有需要用户确认拆表的信息, 并可补充用户拆表 原因信息。
[0043]按照步骤 105, 终端服务器 20接收确认信息表, 选择虚线方框 1030 中所示的 "拆 表"控键, 则会出现如图 5所示的拆表操作界面。 图中, 灰色标记的信息项均不能被用户界 面 10和终端服务器 20两端修改, 而用户在 "拆表原因"一栏可输入文字内容, 终端服务器 20端对此处无法修改, "COMOBOX"代表此信息受前述加密因子控制。 当选择 "确认拆 表"后, 终端服务器 20仅自动删除表计对应的用户号和相应的电力公司、 地区信息表, 而 生成注销请求记录和 "拆表原因"信息并将其存储至远端存储模块 40, 随后反馈用户一系 列 DM— TOKEN信息表。 作为优选, 若被拆下的电表仍可以继续使用, 则需要将此表计所对 应的信息表存储, 而在下次使用时方便调用和对照, 并进行表计信息更新。
[0044]按照步骤 106, 用户界面装置 10向电表 30录入 DM— TOKEN信息表, 所述电表读取 这些 DM— TOKEN信息表后, 反馈一系列 RC— TOKEN信息表。

I0047J按照步骤 109, 若确认存在余额, 则所述终端服务器将所述 MC— TOKEN信息表进行 解码并计算出应退还余额, 生成注销完成记录并将其存储至远端存储模块 40, 若确认不存 在余额, 则直接生成注销完成记录并将其存储至远端存储模块 40。 例如, 此时终端 20显示 出如图 6所示的一个装表操作界面, 首先判断用户下装表的数目或是否装表, 若拆表成功则 "已装电表数 "及时更新, 此时在用户端安装好新表, 安装成功后, 会显示图中所示的若干 用户项 1060。 这时选中一个用户项 1060 (可对多个用户同时操作), 出现图中下方区域的一 个表格栏 1040' , 其中可同样显示用户的表计信息项, 包括例如表号、 表型、 厂商、 SGC、 Ή名称、 拆 /装表日期等, 这些信息项是新表的各项信息, 终端服务器 20将这些信息项加以 编码后存储至远端存储模块 40以便査询。
[0048]在终端服务器 20确认信息正确后, 可选择 "装表"键, 此时出现图 7所示的装表界 面。 其中虚线方框 1080标识的例如 "所属电力公司"、 "所属辖区"或 "表计新增原因"需 要存储于远端存储模块 40中, 然后选择 "确认装表" 1090。
[0049]按照步骤 101, 在用户界面装置 10发送电表注销请求信息表时, 用户界面装置 10与 电表 30对应时钟是否一致, 若一致则发送电表注销请求信息表, 若不一致则进行自身时钟 校准以保证时钟一致, 随后发送电表注销请求信息表。
