1. Safety precautions
Use supply voltage and interfaces indicated in the machine specifications.
In connection/disconnection of cables, the machine power must be switched
off.
Do not use machine in locations close to powerful light sources.
To obtain stable results, wait about 20 minutes after machine activation to
achieve uniform scanner warm-up.
Avoid metal chips getting into the machine body;
Do not allow foreign objects to get between moving and stationary parts of
the measuring machine after turning it on;
Do not obstruct the movement of moving parts of the machine;
Friction parts of the ball screw assembly should be kept clean and be lubri-
cated;
The machine should be grounded and connected to ground line via a sepa-
rate lateral line;
It is not recommended to connect other devices and networks to the host
computer.

4. General information
The measuring machine is designed for non-contact measurement of geomet-
rical parameters of objects, specifically sunflower seeds, and is a standalone software/
hardware system.
Technical characteristics of the machine can be changed for a specific task.
5. Structure and operating principle
The work of the machine is based on the principle of 3D laser scanning of ob-
ject/objects with subsequent construction of a 3D computer model and determination of
geometrical parameters from the model.
The machine structural design is illustrated in Figure 1.
The machine consists of a table 1 whereon a frame structure 2 is located with a
guide 3. Installed on the guide 3 there is a carriage 4 with a laser scanner 5. The car-
riage 4 is driven by a stepper motor 6 by means of a ball screws assembly (not shown).
In the extreme positions of the carriage 4 there are limit switches (not shown). An indi-
cating unit 7 is mounted on the frame structure 2. On the side plate of the machine there
is a power connector 8 (220V) and two network jacks 9 for Ethernet connection. Connec-
tion of the machine to PC 10 is via the network switch 11.
Figure 1
Laser radiation 12 of a scanner 5 is formed into a line 13 and is projected onto
the table 1 where objects to be controlled are located. The laser line length corresponds
to the table width. The resulting images of the contour (section profile) of the objects lo-
cated on the table are analyzed by the scanner signal processor which calculates the

distance to the object (Z coordinate of points) for each of a plurality of points along the
laser line on the object (X coordinate of points).
The machine works as follows.
The laser scanner mounted on the carriage moves along the table 1, the direc-
tion of the movement being the coordinate Y. The laser scanner determines the coordi-
nates of the object profile points (X, Z) at fixed regular linear intervals along the Y coor-
dinate defined by the stepper motor drive. As a result, a 3D computer model of the
scanned area is obtained in the form of a cloud of points with known coordinates (X, Y,
Z). An example of the model is shown in Fig. 3. The required geometrical parameters of
the object are calculated from the resulting 3D model.

8. Preparation for work
Connect the machine according to Fig. 1.
Install Qt version 4.8.0 libraries, Microsoft redistributable package 2010. The
library set up program vcredist.exe is on CD which is part of the supply
package. The software is adapted to the ОS Windows XP, Vista, 7 environ-
ments.
Perform network settings. Ethernet network address space is 192.168.1.Х,
mask word is 255.255.255.0. IP address of the PC should be in the space
specified, Хmust not be equal to 10 (display unit address) and 15 (laser
scanner address).
It is not recommended to connect other network devices and networks to the
host computer.
Calibrate the machine in accordance with par. 9.4.
8.1. Necessary conditions
Necessary conditions to ensure correct operation of the machine are as follows:
seeds should not be in touch with each other so that the size of the gap must
be such that when the laser beam falls between the seeds the scanning area
should be lit by the beam.
seeds should not touch restrictive skirting around the table perimeter.

9. Operating the machine
The geometric parameters measurement cycle is fully automated and operation
of the machine is reduced to the work with the program
The program ensures:
control of the machine in the operation process and debugging modes,
receiving data from the scanner and construction of a 3D model
mathematical calculations
input of sorting parameters
logging of the results
control of the machine status
control of LED indications
calibration of the machine
9.1. Working window of the program
Run the RFSeeds program. When run, the program automatically scans the
network devices and connects to them. If the connection is successful the status line
displays "System Ready", and the working window emerges which is shown in Fig. 4.
Otherwise, description of the connection error emerges.
Picture 4
Control keys are located in the left part of the window. Key functions are as fol-
lows: Start new log report –deletion of all accumulated data;
Measurement –start measurement procedure;
Log report export –formation of log report with measurement results;
Calibration –start calibration procedure;
Last measurement rollback –deletion of the last measurement out of data ar-
ray. The right part of the window contains:

three tabs –Length, Width, Height, and the field boxes common for the tabs:
the box for displaying the histogram of the distribution of seeds in size,
the box for setting the group interval as well as the upper and lower limits of the
size range in histogramming.
9.2. Measurement procedure
Check (form) the parameters of the histogram.
Place the seeds on the table in accordance with the requirements of par. 8.1.
Click the Measurement key. Scanning session will start. If the scanner is not
located at the beginning of the range, it will first be moved to the starting posi-
tion and then scanning will start. The slider in the center of the program win-
dow will display dynamics of the scanning process.
When the scanning is finished, the program will display the number of
scanned seeds and their size distribution.
The result of each subsequent scanning is added to the previous results. To
delete the accumulated data before scanning, click Start new log report key.
If incorrect or incomplete scanning has been obtained, the results can be re-
moved from the accumulated data using the Last measurement rollback
key.
9.3. Logging the results
To obtain log report, click the Log report export key. An example of the report
is shown below.

9.4. Calibration
For the first start of the machine and once a month it is recommended to cali-
brate the machine. To do this, remove all items from the working surface of the machine
table and click Calibration. When the system status changes (e.g., because of transpor-
tation, reassembly), calibration must be carried in a mandatory manner.
9.5. Indicating lights
The indicating lights (see. Fig. 1) show the current status of the machine.
Red LED is lit –failure;
Blue LED is lit –machine is ready for operation
Yellow LED is lit –scanning is in process
10. Maintenance
10.1. General instructions
Maintenance of the machine is carried out to ensure constant-ready status and

Scanner displacement
Calibrate the machine
Scanner is out of
the scanning range
Return scanner to the scanning range with the help of TestSignalBlock.exe program
(included in delivery set)
The program fails to
connect with the
scanner
Perform diagnostics of the scanner with the help of rf620et-sp.exe program and us-
ing description of the scanner. When adjusting the system the DHCP server may
be necessary, it is included with the software (tftpd32) in the delivery set.
Connection to the
machine fails
Check network connections, run the TestSignalBlock.exe program with RFSeeds
out of line. If LEDs are not controlled by clicking checkboxes in this program, it
means that the indicating unit is out of order. If LEDs are controlled but there is no
connection to motor (all motor setting field values = 0), it means that the motor drive
is out of order.
Check Ethernet connection, the work of the network IC card (100 Mb/s connection
should be used), firewall and antivirus program settings. The network should also
allow broadcast access.
