1. 准备工作 / Preparation

(CN) 权限与环境

  • 位置权限：请确保授予“始终允许”位置权限。由于检测通常在熄屏下进行，后台位置权限是里程计算准确的基础。
  • 设备固定：请将设备水平或垂直牢牢安装在检测车辆上。震动传感器对晃动非常敏感，安装不牢会导致数据误差。

(EN) Permissions & Environment

  • Location Permission: Ensure "Allow all the time" is selected. As detection often runs with the screen off, background location is vital for mileage accuracy.
  • Device Mounting: Secure the device firmly (horizontal or vertical) on the vehicle. The sensors are highly sensitive; a loose mount will cause data noise.

2. 实时监测 / Real-time monitoring

(CN) 操作步骤

在什么都不配置的情况下，首页就是实时监测的UI界面，如果将手机合适的固定在移动的设备上，能够清晰的看垂直、水平两个方向的加速度。但是它没有记录的功能，也不会自动同步里程数据。

  1. 点击顶部中间的蓝色开始按钮：在主界面填写、选择“轨道线路名称、行别、车次、车型”等信息。
  2. 启动检测：点击底部的 [开始检测 / MISSION START] 按钮。
  3. 实时监控：
    • 垂加 (Z)：反映轨道高低不平。
    • 水加 (X)：反映轨道水平或拨道问题。
    • 波形图：蓝色代表正常，橙色/红色代表检测到超限波动。
  4. 结束检测： 点击结束检测按钮会立即结束当前的检测，并将检测结果生成检测记录，可以在检测记录里面查看。

(EN) Step-by-Step

Without any configuration, the homepage displays a real-time monitoring UI. If the phone is properly fixed on a moving device, you can clearly see the acceleration in both the vertical and horizontal directions. However, it does not record data and does not automatically sync mileage data.

  1. Click the blue start button in the middle of the top.: On the main interface, fill in and select information such as "track line name, up/down line type, train number, and train type".
  2. Launch: Click the [MISSION START] button at the bottom.
  3. Monitoring:
    • Vertical (Z): Reflects track surface/top errors.
    • Horizontal (X): Reflects alignment/lateral issues.
    • Waveform: Blue indicates normal; Orange/Red indicates threshold violations.
  4. End Detection: Clicking the End Detection button will immediately end the current detection and generate a detection record, which can be viewed in the detection record.

（CN） 警告

  1. 在检测开始记录按钮点击之后，你有6秒的时间将手机固定在合适位置，否则将会因为未固定好产生无效的超限检测数据。在结束时也一样，要先点击结束后，再移动手机。
  2. 必须要确保GPS信号接受正常，否则里程将会不准确。

(CN) Warning

  1. After clicking the "Start Recording" button, you have 6 seconds to fix your phone in a suitable position. Otherwise, invalid over-limit detection data will be generated due to improper fixation. The same applies to ending the recording; click "End" before moving the phone.
  2. Ensure a stable GPS signal reception; otherwise, the mileage will be inaccurate.

4. 线路坐标库管理 / Mapping Library

(CN) 导入与维护

  • 自动采集：开启检测后，系统会自动记录轨迹。
  • 手动校准：如果发现整段里程偏移，可以点击“线路数据”列表中的某条记录，将其设为“锚点”并修改其校准里程。
  • 导出备份：建议定期点击 [导出坐标库]，将测绘好的线路数据保存为 CSV 文件，防止数据意外丢失。

(EN) Management

  • Auto-Logging: The system records the track automatically during detection.
  • Manual Calibration: If the mileage is offset, tap a record in the "Mapping" list, set it as an "Anchor", and edit its calibrated mileage.
  • Backup: Regularly tap [Export CSV] to save your mapped line data to prevent data loss.

线路数据管理的核心功能：锚点与校准 / Core Feature: Anchor Points

(CN) 为什么要用“锚点”？
GPS 定位由于天气或遮挡会有几米的误差。锚点就像是在地图上钉下的“图钉”，它告诉系统：“此时此刻，我正站在精准的 K123+456 位置”。系统会根据这些图钉，自动拉伸或修正整条线路的里程。

(EN) Why use "Anchor Points"?
GPS positioning has an error of several meters. An Anchor Point is like a "Pushpin" on a map. It tells the system: "At this exact second, I am at K123+456". The system then automatically stretches or corrects the entire line's mileage based on these pins.

(CN) 如何插入锚点？

锚点数据需要在现场在基本静止的状态下来准确获取坐标信息来匹配里程。人员在轨道上，以静止的状态，点击插入高精度锚点，输入轨道名称、里程、轨道特征点（曲线、桥路、隧道、道岔）,选择行别，然后点击插入锚点。插入锚点之后系统会重新计算前后锚点之间的所有里程坐标，让里程坐标更加精准。

(EN) How to Insert an Anchor Point?

The operator, stationary on the track, clicks "Insert High-Precision Anchor Point," enters the track name, mileage, track feature points (curve, bridge, tunnel, turnout), selects the row type, and then clicks "Insert Anchor Point." After inserting the anchor point, the system recalculates all mileage coordinates between the preceding and following anchor points, making the mileage coordinates more accurate.

（CN）警告

错误的锚点将会适得其反，反而加大里程的误差，所以锚点的里程与GPS坐标必须做到完全匹配，为了便于核对锚点的正确性，插入锚点时尽量选择线路特征点比较明显的处所，比如曲线的头尾、道岔的最前端、桥梁的起点与终点、隧道的出入口、CPⅢ控制桩位。插入时一定要同步将线路特征点填写记录。

（EN）Wring

Incorrect anchor points will have the opposite effect, increasing the mileage error. Therefore, the mileage of the anchor point must be perfectly matched with the GPS coordinates. To facilitate verification of the anchor point's correctness, choose locations with obvious line features when inserting anchor points, such as the beginning and end of curves, the front end of turnouts, the start and end points of bridges, tunnel entrances and exits, and CPⅢ control stake positions. When inserting anchor points, be sure to simultaneously record the line features.

5. 常见问题排查 / Troubleshooting

(CN) 常见问题

  • 里程不跳动？：检查 GPS 信号是否正常（需在室外环境下）。
  • 波形太杂乱？：检查手机是否晃动，或调高“检测阈值”。
  • 重装应用数据丢了？：请先使用“导出记录”功能将数据存至手机文件夹。
  • 手机在静止状态也会跳动显示垂加、水加数据？： 请对手机GPS传感器进行校准。

(EN) FAQ

  • Mileage not moving?: Check if GPS signal is active (Outdoor environment required).
  • Messy Waveforms?: Check for device vibration or increase the "Threshold" in settings.
  • Data lost after reinstall?: Always use "Export" to save your records to the phone's local storage folder first.
  • Does the phone still display vertical and horizontal data even when stationary?: Please calibrate your phone's GPS sensor.
