下面结合上述应用场景, 对本发明的实施例提供的一种兼容收费方法进 行说明。
本发明的实施例提供了一种兼容收费方法, 实现了在二义性的路径上对 ETC车辆进行收费, 具体过程如图 2所示, 包括:
步骤 201、在车道入口处, OBU与 MTC/ETC车道子系统 1023中的 RSU 进行专用短程通讯, 该 RSU向 OBU发送入口信息, OBU将入口信息写入所 述双界面智能卡的标识文件; 或
在车道入口处, 所述复合读卡器向所述复合通行卡或所述双界面智能卡 写入入口信息。
本发明实施例中, 以涉及车道均为二义性车道为例进行说明。
本步骤中, 在车道入口处, ETC车辆的 OBU与 MTC/ETC车道子系统 1023中的 RSU进行专用短程通讯, RSU向 OBU发送入口信息, OBU将入 口信息写入路径标识文件, 具体流程如图 3所示, 包括:
步骤 301: OBE向 RSU发送 OBU的系统信息;
步骤 302: OBE向 RSU返回 OBU的系统信息;
步骤 303: RSU向车道计算机发送 OBU的系统信息;
步骤 304: 车道计算机验证后, 向 RSU返回验证确认;
步骤 305: SU向 OBE发送读取 OBU的应用文件的指示;
步骤 306: OBE向 RSU返回 OBU的应用文件;
步骤 307: RSU向车道计算机发送 OBU的应用文件;
步骤 308: 车道计算机给 RSU返回验证确认;
步骤 309: SU向 OBE发送获取双界面卡发行信息的指示; 步骤 310: OBE向 RSU返回双界面卡发行信息应答;
步骤 311 : RSU向车道计算机发送双界面卡发行信息应答;
步骤 312: 车道计算机指示 RSU写入入口路径标识;
本步骤之后, 车道计算机验证双界面卡信息;
步骤 313: SU指示 OBE写入入口路径标识;
步骤 314: OBE写入入口路径标识, 并向 RSU返回写入结果; 步骤 315: RSU向车道计算机返回写入结杲;
步骤 316: 车道计算机向控制器发送控制信息;
本步骤之后, 车道计算机形成交易记录。
步骤 317: 控制器向受控设备发送控制信息。 ETC车辆进入收费路段的流程由 RSU、 OBE、 车道计算机、 控制器和受 控设备共同完成, 受控设备指道闸、 LED显示屏、 车道通行灯等由控制器控 制的设备。 在 ETC车辆进入二义性的车道时, 不需要增加空口交互内容, 只 是在原有入口操作流程结束后, OBU将入口路径标识写入双界面卡中的路径 标识文件中。
如果进入车道的是 MTC车辆,则可以将 MTC车辆的复合通行卡上交收 费员进行入口操作。
本发明实施例中, 对 MTC的复合读卡器进行了软件升级, 该复合读卡 器能够读取双界面智能卡, 即当进入车道的车辆为 ETC车辆时, 可以通过复 合读卡器对双界面智能卡执行将入口信息写入路径标识文件的操作。
步骤 202、 所述 ETC路径标识设备向至少一条车道发送路径信息; 步骤 203、 所述 OBU接收到所述路径信息后, 緩存所述路径信息, 并将 所述路径信息写入所述双界面智能卡;
ETC车辆经过 ETC路侧标识设备时, 会收到 ETC路径标识设备发送的 路径信息, 并将路径信息存储在双界面智能卡上, 本步骤如图 4所示, ETC 路径标识设备不停地发送路径信息,当 ETC车辆经过 PRSU通信区域范围内 时, OBU就会接收到路径信息。 OBU收到路径信息后, 首先根据校验字段 判断收到数据的合法性, 如果不合法则丟弃信息。 如果收到的数据合法, 则 提取出路径信息和当前存储的最后一条路径信息进行比较, 如果相同则说明 该路径信息已经成功写入, 丢弃该信息; 如果不同, 则将该路径信息存储到 双面智能卡中。
步骤 204、 在车道出口处, 判断车辆的通行卡的类型;
如果车辆的通行卡为双界面智能卡, 刚认为该车辆为 ETC车辆, 此时, 开始对 ETC车辆的收费操作。
步驟 205、 由 ETC路侧单元 RSU控制车载单元 OBU从该双界面智能卡 中读取路径信息, 并由 RSU将所述路径信息上传给收费平台进行收费; 或, 由复合读卡器读取所述双界面智能卡中的路径信息, 并将所述路径信息 上传给收费平台进行收费。
本步骤中, 如果 MTC/ETC车道子系统 1023在车道出口处置有 RSU, 则 ETC车辆出口收费操作流程由 RSU、 OBE、 车道计算机、 控制器和受控 设备共同完成, 如图 5所示, 包括:
步骤 501 : RSU向 OBE发送读取 OBU的系统信息的命令;
步骤 502: OBE向 RSU发送 OBU的系统信息;
步骤 503: RSU向车道计算机发送 OBU的系统信息;
步骤 504: 车道计算机验证后, 向 RSU返回验证确认;
步骤 505: SU向 OBE发送读取 OBU的应用文件的指示;
步骤 506: OBE向 RSU返回 OBU的应用文件;
步骤 507: RSU向车道计算机发送 OBU的应用文件;
步骤 508: 车道计算机给 RSU返回验证确认;
步骤 509: RSU向 OBE发送读取双界面卡信息的指示;
步骤 510: OBE向 RSU返回双界面卡信息;
步骤 511 : RSU向车道计算机发送双界面卡信息;
步骤 512: 车道计算机验证 界面卡信息;
步骤 513: 验证通过后, 车道计算机计算通信费;
步骤 514: 车道计算机向 RSU发送写入的出口信息和收费信息;
步骤 515: SU向 OBE发送写入的出口信息和收费信息;
步骤 516: OBE向 RSU返回写入结果;
步骤 517: RSU向车道计算机返回写入结杲;
步骤 518: 车道计算机指示 RSU读取路径信息;
步骤 519: RSU向 OBE指示读取路径信息;
步骤 520: OBE向 RSU返回路径信息; 步骤 521: RSU向车道计算机返回路径信息;
步骤 522: 车道计算机向控制器发送控制信息;
本步骤之后, 车道计算机形成交易记录。
步骤 523: 控制器向受控设备发送控制信息。
增加二义性路径识别功能后, ETC车辆的出口操作流程需要增加读取路 径信息操作, 在原有交易操作结束后, RSU向 OBU发送读取路径信息指令, OBU将双界面卡中存储的路径信息上报给 RSU, 由 RSU将路径信息发送给 收费平台进行收费。
如果在车道出口没有 RSU, 而是使用升级的复合读卡器, 当 ETC车辆 在驶离高速公路时, 需要将双界面智能卡从 OBU上拔出, 交由收费员进行 出口收费操作。 在原出口操作流程结束后, 读取该双界面智能卡中的路径标 识信息。
此外, 当 ETC车辆经过 ETC路侧标识设备时, 如果双界面智能卡此时 未插入 OBU中, 则路径信息会緩存在 OBU中, 待双界面卡插入后进行路径 信息的同步。 ETC车辆在通过 MTC车道进行出口操作时, 收费员应监督司 机进行一次双界面卡插入 OBU的操作, 以确保路径信息的同步。
本发明的实施例提供的兼容收费方法,在不破坏 ETC原有系统流程的前 提下, 增加了若千个接口, 同时兼容了 ETC系统和 MTC系统。
从 ETC设备上来看, RSU、 OBU和双界面智能卡, 都可以支持二义性 路径, 不需要对其进行硬件改动, 只需要进行软件升级即可。
对于 RSU, 需要增加一个和 OBU之间的路径交互接口, 完成路径信息 的读取。 同时在向收费平台 (如计费计算机)上报交易结果时, 增加路径信 息内容。对于 OBU, 需要增加接收路径信息接口和向欢界面卡写入路径信息 接口, 同时增加向双界面智能卡同步路径信息的接口。 OBU的嵌入式安全模 块( Embedded Secure Access Module, ESAM ) 中的 ETC应用目录中的 0x03 文件为 ETC应用保留文件,可以用来缓存路径信息。对于双界面卡, 其 0008 文件为保留文件, 可以用来存储路径标识信息。
本发明的实施例提供了一种兼容收费方法, 通过在二义性路径上添加
ETC路侧单元, 在车道出口处, 通过 RSU控制车载单元 OBU从 ETC车辆 的双界面智能卡中读取路径信息,并由 RSU将所述路径信息上传给收费平台 进行收费; 或由复合读卡器读取所述双界面智能卡中的路径信息, 解决了在 二义性的路径上无法实现对 ETC车辆进行收费的问题。进一步的,路段收费 中心和管理中心的原有软件系统不需要做任何改动,可直接将 ETC路径标识 设备与原有路侧标识设备进行统一管理。对于异地无路径标识的 ETC车辆进 入本地时, 在正常交易后不发送读取路径信息指令, 而是按原有流程正常结 束交易。 本地车辆进入无路径识别的地区时, 其 RSU不会对 OBU发送读取 路径信息指令, OBU可按正常流程结束交易, 适用范围极广。

其中, 双界面只能卡收费模块 601和复合收费模块 602针对两种不同的 模式兌取路径信息, 并将该路径信息上报给收费平台以进行收费。
进一步的, 上述通行卡读写设备如图 7所示, 还包括:
入口信息写入模块 603, 其设置为: 在车道入口处, 与所述 OBU进行专 用短程通讯, 向所述 OBU发送入口信息; 或
向所述双界面智能卡写入入口信息。
