BumpRecroder can be used without an ID, but if you register an ID, you can view only
your data or download data. There are two types of IDs: a free ID that does not require amonthly fee, and a paid ID that has a monthly or annual contract.
Data with no ID or free ID can be shared and viewed by others. Paid ID data is private
and only your group members can view it.
1.3.1. Get free ID

Access the following URL with a browser on
your computer.
https://map.bumprecorder.com
When the screen is shown in Fig. 1.3 opens,press the “Get Free ID” button at the top
right of the screen.
When the user registration screen is shownin Fig. 1.4 opens, enter your user name andpassword and click the “Register” button.

Fig.1.3. BumpRecorder Web initial
screenIf the ID has already been used, it cannot be registered. Please register with another name.
There is no monthly usage fee or annual usage fee, and there is no charge for browsing
the map screen or downloading measured raw data. Downloading analysis data such as
IRI will be charged at the time of download. (PayPal credit card payment)
1.3.2. Get paid ID

Paid ID requires a monthly contract or anannual contract. Please contact us for thecontract. After the contract, a group will
be set up for your company, and you will
be notified of your paid ID registration
URL. The paid ID registration screen isalmost the same as Fig. 1.4. If the ID you
are trying to register has already beenregistered (including a free ID), you
cannot register. Please register withanother name.

(Depending on the contents of the contract, there may be a charge for usage).
1.4. Application ID setting
Set the ID obtained from the browser on the computer to the application. Open the
Smartphone app BumpRecorder on your Smartphone. There are [Navi] [Graph] [Cam][List] [Web] [Settin] tabs for switching functions at the top of the screen.
When you tap (press) the [Setting] tab, the screen shown in Fig. 1.5. opens. Tap “User ID
not set” in the ID set at the top of the screen.
When the screen is shown in Fig.1.6. opens, enter the ID and password that you obtainedon the computer first and press the “Set” button.
* Note: If you open the ID setting screen in Fig. 1.6. after setting the ID, the ID andpassword are displayed. This is a display for when you have forgotten your ID or
password. Do not show this screen to others.

2.1. Installation in the car
The orientation of the Smartphone can be flat, vertical, horizontal, or diagonal (Figure2.1). However, please fix it firmly so that it does not scatter.
When installing using an in-vehicle mounted, if the lower surface of the Smartphone islifted as shown in Fig. 2.2, the mounted itself vibrates and the measurement is likely to beaffected. Make sure that the lower surface of your Smartphone does not vibrate against
the dashboard. Since the dashboard has wrinkles (fine folds), we recommend using a geltype sucker (sucking sucker) as the vehicle mounted.
It is also easy to cut the “seismic (vibration)
gel sheet” sold at home centers andelectronics stores and paste it on the back of
the Smartphone (Fig. 2.3.) and place it flaton the dashboard (Fig. 2.4). The dashboard
is curved, so if you have a single large gel
sheet, it will be scrambled per point. If it is
4 places, it will be the same as a 4 legs chair,etc. The trick is to put them apart to draw as
Fig.2.1. Installation in one carlarge a triangle as possible.

Fig.2.2. Bad example

Fig.2.3. Gel 3 points

holders)

Fig.2.4. Lay the Smartphone on
the Dashboard

2.2. Location of Smartphone
For road surface, property measurement vehicles, etc., measure with OWP (Outer Wheel
Path: left survey line), so if you want to compare with those data, install a Smartphone on
the left end of the dashboard. If you want to measure/evaluate IWP (Inner Wheel Path:
right line), install it at the right end of the dashboard.
* Note: Installation in the center of the dashboard is not recommended because it will be
underestimated because it will be smaller than both the left and right values.
62.3. Measurement start/end
It will be explained on the [Graph] tab screen. The [Navi] tab is the same, although thedisplayed content is different. For the measurement on the [Cam] tab, also check “4Advanced (front-side photography)”.
Launch the app and open the [Graph] tab.
• Upper left: Round graph showing GPS information (GPS circle);• Upper right: Round graph showing turning and acceleration/deceleration (turning
circle);• Center: Graph showing acceleration (Acceleration graph);• Lower: There is a [REC] button that starts and ends measurement. (Fig. 25 to Fig.
27).
The GPS circle turns red for a while after starting the app or when GPS is not available,
such as in a tunnel, and NOT Fix is displayed at the bottom right of the circle (Figure 2.5).
IRI cannot be calculated because the position is unknown even if measured in this state.
The number of GPS satellites visible at the bottom left of the circle is displayed.
Positioning (Fix) is not possible unless the number is 4 or more. If a gray dot appears in
the circle, the GPS satellite is visible, so it will be fixed if you wait for a while. When
fixed, the circle turns green, and the speed is displayed in the upper left corner of thecircle, and the altitude (example: H = 51m) and positioning accuracy (example: Acc =3m) are displayed in the lower right corner of the circle (Fig. 26). Please measure in thisstate.
The sampling frequency of the sensor is displayed above the [REC] button. A = 400Hz is
the sampling frequency of the acceleration sensor is 400Hz, G = 400Hz is the gyro sensor,
and M = 10Hz is the sampling frequency of the geomagnetic sensor.

Fig.2.6. GPS is available

When the [REC] button is pressed, measurement starts and the bar in the button changes
from gray to red. The acceleration graph and swivel circle
display start. The red line in the acceleration graph indicatesvertical acceleration, and the green line indicates verticaldisplacement. The remaining battery level and battery
temperature are displayed in the upper right of the graph.
The elapsed time from the start of measurement is displayedin the lower right corner of the turning circle and is counted
up. The white circle indicates turning, the orange circle
moves up and down the screen, and the left and rightmovements indicate centrifugal force.
If you press the [REC] button during measurement, themeasurement ends and the comment input screen appears asshown in Figure 2.8. Input is optional.
This is a memorandum function that allows you to know themeasurement conditions later.

Fig.2.8. At the end of measurement8* Note 1: Please note that the Smartphone’s OS shuts down when the battery temperaturereaches 50 degrees Celsius.
* Note 2: When measuring continuously for a long time, the measurement file isautomatically divided (automatically ends and resumes immediately) in about 2 hours.
2.4. Notes on measurement
BumpRecorder automatically corrects the inclination of the Smartphone and the different
type of vehicle. There are some caveats for this correction.
Essential• Acceleration sampling frequency must be at least 50Hz and recommended 200Hz
or higher;• Travel 2 km or more at 20 km/h or more;• Start, stop, right turn, left turn multiple times each;• Include roads that are not too flat (such as residential roads);• Secure your Smartphone.
Recommendation• It is recommended to measure while charging because the battery is depleted
quickly in order to obtain GPS at the highest speed, acceleration, and gyroscope
every second.
• For the same reason, the temperature of the Smartphone
tends to rise. Apply a black felt cloth to improveventilation and avoid direct sunlight. For white cloth,
black is recommended because it appears inside the front
window, making it difficult to see the front.
2.5. Upload
Obtain the index such as IRI and upload the measurement data
to the server for display on the map.
Open the [List] tab. A list of measurement data is displayed.
Displays the date and time when the measurement was started(this date and time become the file name of the measurementdata), the measurement distance, and whether or not it was
uploaded. If a comment has been entered, the comment is also
displayed.
Fig.2.9. List of data

Check the checkbox to the left of each row, and press the upload button (up arrow iconon the document) at the bottom right of the screen, a confirmation screen will be
9displayed, and if you click "Yes", the data will be uploaded (transferred) to the server.
About 10 minutes after uploading, the results will be displayed on BumpRecorder Web.
https://map.bumprecorder.com
2.6. Deleting data
Check the checkbox on the left of each line in the [List] tab,and press the delete button (trash can icon) at the bottom left ofthe screen to display a confirmation screen. Press “Yes” todelete the data. It cannot be revived. Please be careful.

3. Application (Fully automatic measurement)
If you take power from the car's cigar socket and permanently
install the Smartphone in the car, you can automatically start
the application → start measurement → end measurement →upload → end the application according to the engine ON/OFF.
Fully automatic measurement is possible without any operation.
Set the following three items on the [Setting] tab. The initial
setting when installing the app is OFF for all functions.
Fig.3.1. External power

3.1. External power supply interlocking
supply interlock
This is a setting for operating the USB cable to power the Smartphone (Figure 3.1).
• Select “Measure in conjunction with power” to turn on
the function. Start application and start measurement
when the power supply starts. The measurement ends
and the application ends when the power supply ends;• Selecting “Do not interlock with power” turns thefunction OFF, and measurement will not start or end
unless you manually press the [REC] button on the[Graph] tab.
The default setting is “Do not synchronize power”.
3.2. Data upload
Settings for uploading when power from the USB cable iscompleted (Figure 3.2).
• Select “Manual upload” to turn off the function and not
upload when the power supply ends. This is a setting for
uploading via Wi-Fi without using SIM (with mobile
network communication OFF).
Use the [List] tab to upload.
10

Fig.3.2. Data upload• Select “Automatically when finished / split” to turn on the function and uploadwhen the power supply ends. If you measure continuously for a long time and thedata is divided in about 2 hours, it will also be uploaded automatically.
The default setting is “Manual Upload”.
3.3. Automatic deletion settings
This function deletes unnecessary data when the application ends (Figure 3.3).
• Select “Manual delete” to turn off the function and do
not delete the data when the application is closed.
Select this if you want to keep the data on your
Smartphone. Use the [List] tab to delete it;• Select “Automatically when finished / split” to turn on
the function, and when the application ends, the datawith zero measurement distance and the uploaded data
are deleted.
The default setting is “Manual deletion”.
When operating with automatic measurement, data
accumulates on the Smartphone, and there is not enough freestorage space. In extreme cases, the operation of theSmartphone’s OS may become strange. This function deletes
unnecessary data to prevent this.
Fig.3.2. Automatic deletion
setting* Note 1: When operating on a Smartphone, if the remaining battery power of theSmartphone becomes zero after weekends or holidays, the Smartphone will only becharged with the power off even if the power supply is started. As a result, measurement
will not start. In this case, turn on the power manually;* Note 2: When operating on Biglobe's IoT terminal BL-02 provided by our company,
even if the power is turned off due to the remaining battery level being zero if the power
supply is started, the power of the terminal will be turned on for a while and themeasurement will begin. This is recommended because fully automatic measurement ispossible.

4. Advanced (front photo shooting)This is a method for acquiring a front image (road surface
image) with the back camera of the Smartphone
simultaneously with sensor information measurement (roadsurface property measurement). Settings are required on the[Setting] tab. Only the [Cam] tab can be used for shooting
during measurement. You cannot shoot on the [Graph] tab or[Navi] tab.
4.1. Front image capture interval
It is useless to shoot and upload the same images whileparked, such as when waiting for traffic lights. Therefore,
BumpRecorder shoots every fixed distance so that it doesn'tshoot while stopped (Figure 41).
・ Select “Do not shoot” to turn off the function, and even if
you start measurement on the [Cam] tab, it will not be shot.
・ If you select "Every 10m", a picture is taken every 10m.
(Same for other distances)
The default setting is “Do not shoot”.

Fig.4.1. Front image
capture interval

4.2. Image compression settings
Since images are quite large in file size, it takes time to upload
and requires a lot of storage size. This is a setting to reduce thesize by increasing the compression rate of the image (Fig. 42).
However, please note that increasing the compression ratio will
lower the image quality.
• If the slide bar is set to the right, the image quality will
be improved. (The compression ratio is worse and thefile size is larger).

• If the slide bar is set to the left, the compression rate will
increase. (Image quality will deteriorate).

4.3. Front image upload
Select the upload timing (Fig. 43).
• If you select “Post-upload”, the upload will not be
performed during measurement shooting. Use the[List] tab to upload.
• Select “Real-time automatic” to upload during
measurement shooting. A SIM card is required because
it will be uploaded via mobile communication. The
image is large in size and post uploading over Wi-Fi
takes a lot of time. This is useful when you want to
reduce the actual waiting time, or when you want toknow the actual situation at the office quickly.
The initial setting is “Post-upload”.

Fig.4.3. image upload

4.4. Installation in car
Use the in-vehicle mounter to place it vertically on the dashboard (Fig. 44). Current
version 5.0.8 is for vertical installation only.
As in “2.1 Installation on a car”, use the gel sucker
mounter and attach the lower surface of theSmartphone to the dashboard.
When mounted on the front window, it is easy for the
Smartphone to shake, and the road surface property
measurement is likely to be affected. Many mountersassume horizontal installation, but the current versionof the app does not support horizontal installation.
Not recommended from.
Fig.4.4.Smartphone installation for
front image capture* Note: When installing on the front window, please follow the “Safety Standard forRoad Transport Vehicles”.
Extract: “Camera for obtaining information on road and traffic conditions” as describedin “Article 29 (Window Glass) Window Glass Technical Standards” It sticks to a range
within 20% of the actual length of the glass opening on the vertical plane parallel to theline. "

4.5. Measurement start/end
Only the [Cam] tab can be used for shooting during
measurement (Fig. 45). You cannot shoot on the [Graph] tab or[Navi] tab.
Press the [Photo] button at the bottom right of the screen to
start measurement and shooting. Press the [Photo] button again
to stop measuring and shooting.
If you move to the [Graph] tab or [Navi] tab during
measurement, the measurement will continue but shooting willend. Shooting continues even after returning to the [Photo] tab.
To shoot again, stop the measurement and restart themeasurement on the [Photo] tab.
At the top of the screen, the elapsed time, speed, measurement
distance, GPS satellites visible below, battery level, battery
temperature, and air pressure are displayed from the left.
An acceleration graph is displayed at the bottom of the screen.
Fig. 4.5. Front image capture

4.6. Post-upload
To upload an image taken with the “Upload forward image” setting on the [Setting] tab
set to “Post-upload” or an image that could not be uploaded in real-time after
measurement, upload the corresponding data on the [List] tab. Measurement data andphotos are uploaded as a set. It is not possible to upload only data or photos.
4.7. Deleting images
Check the checkbox on the left of each line in the [List] tab, and press the delete button(trash can icon) at the bottom left of the screen to display a confirmation screen. Press“Yes” to delete the data. It cannot be revived. Please be careful. It is not possible to delete
only data or photos.
