User Interface Does Not Update GPS Location

Usage:

- PL5
当"用户接口"中的 GPS 位置没有更新时,可以在驶入客户现场前执行特定步骤。 遵循 "场外诊断" 中的步骤,以帮助在驶入客户现场前确定故障。

注: 此步骤仅适用于使用 Caterpillar 提供的无线电和 GPS 的客户。

场外诊断

注: 部分 "场外诊断" 章节的步骤取决于现场的客户。

  1. 选择 VisionLink 上的 "Update(更新)"按钮后,确保 "User Interface(用户接口)"从设备接收新的数据。

    1. 如果网络管理器登录且 GPS 位置得到更新,则将系统重新投入使用。

    2. "用户接口"没有接收新数据。 请参阅系统操作、故障诊断与排除、测试和调整, M0079294, "蜂窝无线电无法通信"。

    3. "用户接口"接收来自设备的数据,但 GPS 位置不更新。 参考步骤 2。

  2. 请求设备位置。 询问客户设备位于何处以及无线电天线是否具有清晰的对空视野。

    1. 如果设备在建筑物内或位于大型障碍物下方/附近,则要求客户尝试将设备移至具有清晰的对空视野的更开阔的位置。

    2. 如果设备位于具有清晰的对空视野的位置,请参阅专门说明书, M0077632,了解蜂窝无线电的正确放置。

    3. 如果蜂窝无线电处于适当位置,请参阅 "现场诊断"。

现场诊断

  1. 目视检查无线电布置。 请参阅专门说明书, M0077632,了解正确的无线电安装,因为本设备只有内置天线。

    1. 如果无线电/天线布置不正确,并且没有对空视野,请更正天线布置,并检查新的位置报告。

    2. 如果无线电/天线布置良好,且无线电具有对空视野,则转至步骤 2。

  2. 检查 PL542 无线电上的橙色 LED。

    1. 如果橙色指示灯闪烁,则无线电无法获取 GPS 位置。 如果无线电具有对空视野,且橙色指示灯在 10 分钟内没有稳定点亮,则转至步骤 4。

    2. 如果橙色指示灯稳定点亮,则转至步骤 3。

  3. 为使 PL542 发送 GPS 位置, PL542 必须连接到因特网。 检查此因特网连接的黄色指示灯的状态。

    1. 如果黄色指示灯无法保持稳定亮起,请参阅 M0079294, 蜂窝无线电无法通信。

    2. 如果黄色指示灯和橙色指示灯稳定亮起,且设备无法发送有效的位置,则转至步骤 4。

  4. 更换无线电。

    1. 如果更换无线电排除了故障,则将系统重新投入使用。

    2. 如果更换无线电没有排除故障,则转至步骤 5。

  5. 通过您的代理商 TC 从 Caterpillar 获得更多服务技术帮助。 如果要发送服务请求,则 TC 可以通过 "PSCRM" 系统输入"产品技术"服务请求。
