Manhole Data Entry on Mobile Devices with WinCan MobileApp

Version: 2.2

Date: 10.12.2024

Introduction

Data entry for manholes can be done via the pipe inspection software WinCanVX or the WinCan MobileApp running on mobile devices.

This small application is available for free via Google PlayStore and has been designed for the following operating systems or platforms:

• Android tablet computer

• Android SmartPhone

• Apple-IPhone

An easy and self explanatory user interface allows TV operators to enter the following basic manhole data and upload them directly to the WinCan CLOUD:

• Manhole main data: name, town, street, depth to invert, X/Y coordinates…

• Manhole inspection data: date, operator, inspection type and purpose, wheather

• Manhole parts: cover, cone, chamber, bench…

• Inlets and outlets: drawn on photo or graphical clock sketch

The usage of the WinCan MobileApp always requires a WinCanWeb account with the FLEX mode activated. Once the account data are saved on your mobile device (SmartPhone or tablet computer) you can create a project, enter manhole data, link video clips and photos to each manhole and finally upload it to your workspace on the WinCan CLOUD.

The FLEX mode then allows the user to complete the manhole data and create the reports directly on the CLOUD where the project link is finally sent from to the end customer.

Data recording with built-in camera of SmartPhone or tablet computer

1.) Run the MobileApp, go to Settings, select the language for your country and set the video resolution to HD (High Definition).

2.) Check your Web account data (i.e. username and password), confirm all settings hitting the button Save settings. The command Back then always gets you back to the previous view:

3.) Create a new project based on the damage assessment standard which is mainly used in your country/region OR import an existing project from the CLOUD:

4.) Enter at least the following data for each manhole. Hit the arrow icon to the right to open or close the corresponding data input mask:

• Manhole name

• Manhole depth (measured from cover to bottom)

• Town

• Street

• Date of inspection

• Name of the operator

• Cover shape

• Cover diameter and width

• Manhole entries: type (inlet or outlet), clock position and drop. Hit the button From sketch to set the clock position of the inlet or outlet. Set the main outlet at the position 12 or 6 o’clock:

• Position of the manhole: the coordinates are provided by the GPS receiver of the mobile device (SmartPhone or tablet computer). Hit the button Set location, move the mobile device (green icon) to the center of the manhole and confirm the current position hitting the button set current as node position: a red icon then shows the manhole position. You can still move the red icon to adjust the manhole position keeping the finger on the desired location. Finally hit the SAVE button to return to the data entry mask.

4.) Manholes without defects: take 3 or 4 photos per manhole:

• Photo of the manhole and its surroundings (for easier localization)

• Photo of the manhole cover

• Photo of the manhole taken from the cover level (0.00 m)

• Photo of the manhole bottom

5.) Manholes with defects: take 1 picture per defect

6.) Record one video clip (app. 30 sec) per manhole

Data transfer

Go to Settings > Login, enter the user credentials for your Web account and save the settings.

• Go back to the project list, select the desired project and hit the cloud icon.

• Next hit the Upload button to have the project uploaded to the WinCan CLOUD: a user friendly display is going to inform the user continuously about the upload progress which is particularly important in case of large manhole projects.

• Launch your Internet browser and log in with your Web account.

• Check whether all manholes have been uploaded together with the corresponding video clips and photos. In case of large manhole projects it can last more than an hour until the videos can be played back.

Data recording with QV360 camera from iPEK

It is recommended that this job is done by 2 operators

1.) Run the Mobile App, go to Settings, select your country and check your Web account data (i.e. username and password). Finally save your settings.

2.) Hit the button Devices and enter Bluetooth as well as the camera serial number into the corresponding text field. You can get both serial numbers form your personal WebCloud Voucher:

3.) After you have entered both serial numbers, take the camera head, push the blue START button and activate the Bluetooth hardware interface with the small button located next to the camera lens.

4.) Go back to the MobileApp, hit the button Connect and mind the wireless connection icon that should switch from RED to WHITE: the MobileApp is now ready to receive the camera signal.

5.) Go back to the project list, select the language for your country and set the video resolution to 4K

6.) Create a project based on the damage assessment standard which is mainly used in your country (WRC, PACP, WSA, NZPIM etc.).

7.) Enter at least the following data for each manhole you are going to scan with the QV360 camera

• Manhole name

• Town

• Street

• Date of inspection

• Cover shape

• Cover diameter and width

• Position of the manhole: the coordinates are provided by the GPS receiver of the mobile device (SmartPhone or tablet computer). Hit the button Set location, move the mobile device (green icon) to the center of the manhole and confirm the current position hitting the button set current as node position: a red icon then shows the manhole position. You can still move the red icon to adjust the manhole position keeping the finger on the desired location. Finally hit the SAVE button to return to the data entry mask.

8.) Hit the button QV360 and make sure you are connected to the QV360 device.

9.) Set the luminosity slider to 75% or higher

10.) Click on Start preview to set the start point of recording; mind the cover ring appears on app. 75% of the image height:

The manhole depth will be measured automatically during video recording.

11.) Hit the button Start Inspection and confirm the cover diameter in the message that pops up:

12.) Slide down the camera pole vertically, steadily and slowly from the cover level to the bottom and mind the state of the information panel that flashes up in the WinCan Mobile App:

MOVE → movement OK

SLOW → slow down movement

STOP → recording finished → slide up the camera stick

13.) As soon as the video recording has finished the video clip is downloaded automatically from the QV360 camera.

14.) Go back to the manhole list, select the desired manhole and hit the button Media to play back the assigned video clip.

So you can make sure there is a clip available, check the video quality and repeat the inspection if necessary.

15.) Finally take 2 pictures for the selected manhole from the built-in camera of your SmartPhone or tablet computer hitting the command Add > Photos:

• Photo of the manhole and its surroundings (for fast and easy localization)

• Photo of the manhole cover

Data transfer

Go to Settings > Login, enter the user credentials for your Web account and save the settings.

• Go back to the project list, select the desired project and hit the cloud icon.

• Next hit the Upload button to have the project uploaded to the WinCan CLOUD: a user friendly display is going to inform the user continuously about the upload progress which is particularly important in case of large manhole projects.

Data processing

Data processing based on the video clip runs automatically after upload. Hit the button Project>AI scan jobs to follow the progress in a separate panel:

Once the AI scan jobs have finished, hit the menu button to the right of the desired manhole record and select the command Edit node:

Left to the data entry mask there will be available 3 different views for each manhole:

• 360° video view

• 3D view of the manhole structure. Use this view to measure the dimensions of the manhole and its parts (cover, cone, chamber, channel etc.)

• 2D view of the unfolded manhole wall. Use this view to measure the dimensions of the manhole parts and to clearly detect any kind of defect.
