1. Create a device in flespi. To do this, open the Devices tab in the Telematics Hub, click on the button  in the lower right corner of the screen, fill in the required fields, and click Save.
   
2. Create a channel to receive data in flespi: open the Channels tab, click on the button  in the lower right corner of the screen, fill in the name and protocol_id fields (the protocol corresponds to the type of the physical device), and click Save.
   
3. Point the physical device (tracker) to the channel address (IP and port).

4. Create a stream to redirect data. To do this, open the Streams tab, and click . Fill in the сonfiguration and uri (address of the flespi gateway device) fields, activate the ident option.

   IP varies depending on the data centre.

   

5. Assign the flespi device created in step 1 to the stream. To do this, go to the Devices tab and click on the line with the flespi device to open the settings window. Next, on the Streams tab, click  and select the required stream.
   
6. Copy a token on the flespi platform (the Tokens tab).
   
7. In Wialon, paste the copied token into the Token field on the Security tab of the top account settings.
   
8. Create a unit in Wialon. The device type should be the one indicated in the Device type field in step 1. It should be marked as flespi in brackets.
   
9. Create a new command in the unit properties in Wialon.
   
   When creating the command, you can configure its parameters in the flespi form. In this way, you will not have to do it manually every time before sending the command to the unit.
   
10. Send the command to the unit from the Monitoring tab.
    
11. If the parameters of the command were not configured in its settings, specify them in this step.
    

1. Empty the fuel tank. Make sure the car battery is charged and won't die during the calibration.
2. If the FLS is not installed yet, install it according to the manual.
3. Configure the tracker in such a way that the data is saved at least once every 10 seconds while you are calibrating the tank.

4. Prepare a table with two columns: X and Y. In the Y column, you should indicate the amount of fuel in the tank, and in the X column, the corresponding voltage value. To find out this value, request data messages from the unit in the Wialon monitoring system and find the value of the FLS parameter (this parameter is different for different trackers).

   We don't recommend using a voltmeter to determine the X value due to the voltage drop in the circuit and the accuracy difference between the voltmeter and the tracker.

   If you are using a digital FLS, you can take the values for the X column from the configurator (a special application for fuel level sensors).

   The table should contain as many rows as you conditionally divide the tank into parts, as well as an additional row corresponding to a volume of 0 litres.

5. Write down the start time of the calibration. You can also write down the time of adding each part of fuel to find the corresponding messages in Wialon easily.
6. In the X column of the first table row, specify the voltage value before adding the fuel. Enter 0 in the Y column of this row.
7. Divide the entire volume of the tank into 10-20 parts.
8. Pour a part of fuel. In the Y column, enter the resulting fuel volume in litres. Wait 2-3 minutes until the fuel level in the tank becomes even and the tracker records a few more messages.
9. Repeat the previous step until you fill the entire tank.
10. In Wialon, take several messages generated 2-3 minutes after adding each part of the fuel. In these messages, find the parameter with the voltage value from the FLS, calculate the average voltage value ​​for each such group and enter it in the X column.

Next, follow the instructions for filling out the calculation table in Wialon.

See the examples of configuring a calculation table for an FLS here.

Other command types

The data sent by the device, such as photo and video files, is stored on the CMSV6 server. Only links to these files are sent to Wialon. To get access to them, you should create a command of the corresponding type in the unit properties.

download_video

When this command is sent, video recordings are uploaded from the device to the CMSV6 server. If there is no connection to the device, the query execution is postponed until the device is connected to the server. To see if the video is uploaded to the CMSV6 server, execute a get_video_records_info command.

get_video_records_info

This command allows you to query information about the video that is stored in the device or on the CMSV6 servers. You can select the location of the data in the properties of the command.

After the command is executed, if there are available files, the icon  becomes active on the Monitoring tab (the Media option). Besides, a numeric indicator shows up over the same icon in the bottom panel.

Besides, you can query messages from units for the required interval (the Data messages type, show parameters as raw data). The icon  will be displayed in the Media column of the resulting table. Click on it to view the found photo and video files.

The messages with media files contain the following parameters:

• video uri: the link for playing the video;
• loc: the file location (loc=2 indicates that the file is stored on the CMSV6 storage server);
• cha_n: the number of the video channel.

get_gps_status

This command allows you to query the last GPS location.

get_photo

Using this command, you can query a photograph from the camera in real time.

get_track

The command allows you to query the telematic data of the unit for the indicated period (similarly to the import of messages in Wialon).

This guide describes how to prepare a device manufactured by Teltonika and to configure a unit which uses this device so that the Eco Driving application can work with this unit. The guide is suitable for all devices of the FMB, C, M, U lines, except for the FMC640, FMM640, FMB640 models.

1. Configure the 258 parameter (Eco Driving Maximum) in the device.
   
2. Open the Sensors tab of the unit properties in Wialon.
   
   
3. Create a custom sensor Accel_MAX. In the Parameter field, specify the following formula:
   (((io_258:48*const32768)-

   (io_258:33*const1+io_258:34*const2+io_258:35*const4+io_258:36*const8+io_258:37*const16+i

   o_258:38*const32+io_258:39*const64+io_258:40*const128+io_258:41*const256+io_258:42*cons

   t512+io_258:43*const1024+io_258:44*const2048+io_258:45*const4096+io_258:46*const8192+io

   _258:47*const16384))*io_258:48)/const1000
   
   

4. Create a custom sensor Brk_MAX. In the Parameter field, specify the following formula:
   ((-

   (io_258:33*const1+io_258:34*const2+io_258:35*const4+io_258:36*const8+io_258:37*const16+i

   o_258:38*const32+io_258:39*const64+io_258:40*const128+io_258:41*const256+io_258:42*cons

   _258:47*const16384))*(io_258:48-const1))/const1000
   
   

5. Create a custom sensor Crn_MAX. In the Parameter field, specify the following formula:
   (-

   (io_258:17*const1+io_258:18*const2+io_258:19*const4+io_258:20*const8+io_258:21*const16+i

   o_258:22*const32+io_258:23*const64+io_258:24*const128+io_258:25*const256+io_258:26*cons

   t512+io_258:27*const1024+io_258:28*const2048+io_258:29*const4096+io_258:30*const8192+io

   _258:31*const16384))*(io_258:32-const1))/const1000+(((io_258:32*const32768)-

   (io_258:17*const1+io_258:18*const2+io_258:19*const4+io_258:20*const8+io_258:21*const16+i

   t512+io_258:27*const1024+io_258:28*const2048+io_258:29*const4096+io_258:30*const8192+io

   _258:31*const16384))*io_258:32)/const1000
   
   

6. Open the Eco driving tab and add custom criteria for the created sensors.
   
   
   • The Acceleration criterion for the Accel_MAX sensor.
     
     
   • The Braking criterion for the Brk_MAX sensor.
     
     

   • The Cornering criterion for the Crn_MAX sensor.
     

     
     

Now you can track the driving quality of the unit in the Eco Driving application.

Some devices allow transferring user data. In Wialon, this data is registered as unsigned integers by default, regardless of the form in which it is sent from the device. In order for the reports and messages in Wialon to display  "clear values", that is, the values as they are sent from the device, you can use the bitwise parameter control method. This guide describes three examples of using this method to work with source data.

Example 1

Consider the case when a unit sends data, for example, in the user_d1 parameter as two double-byte unsigned integers. In Wialon, this data is registered as user_d1=2646793773.

1. Convert the received number in Wialon to the binary system: 2646793773 → 10011101110000101101111000101101.
   

   In Wialon, bits are calculated from one.

2. Divide the resulting number by two (according to the double-byte number count): 1101111000101101 and 1001110111000010.

3. Create a custom sensor numeral_1 in the unit properties in Wialon. In the Parameter field, specify the following formula:
   

   user_d1:1*const1+ user_d1:2*const2+ user_d1:3*const4+ user_d1:4*const8+ user_d1:5*const16+ user_d1:6*const32+ user_d1:7*const64+ user_d1:8*const128+ user_d1:9*const256+ user_d1:10*const512+ user_d1:11*const1024+ user_d1:12*const2048+ user_d1:13*const4096+ user_d1:14*const8192+ user_d1:15*const16384+ user_d1:16*const32768

   
   
   

4. Create a custom sensor numeral_2. In the Parameter field, specify the following formula:
   

   user_d1:17*const1+ user_d1:18*const2+ user_d1:19*const4+ user_d1:20*const8+ user_d1:21*const16+ user_d1:22*const32+ user_d1:23*const64+ user_d1:24*const128+ user_d1:25*const256+ user_d1:26*const512+ user_d1:27*const1024+ user_d1:28*const2048+ user_d1:29*const4096+ user_d1:30*const8192+ user_d1:31*const16384+ user_d1:32*const32768

   
   

As a result, the reports and messages in Wialon display the values of two double-byte sensors (numeral_1=56877 and numeral_2=40386) instead of user_d1=2646793773.

Example 2

In this example, consider the case when a unit sends data as a number with floating point (float). In Wialon, the data is registered as user_d3=1017282565.

1. Convert the received number in Wialon to the binary system: 1017282565 → 111100101000101000000000000101.

2. Create a custom sensor float in the unit properties in Wialon. In the Parameter field, specify the following formula:
   

   const-1^user_d3:32*const2^((user_d3:24*const1+user_d3:25*const2+user_d3:26*const4+user_d3:27*const8+user_d3:28*const16+user_d3:29*const32+user_d3:30*const64+user_d3:31*const128)-127)*(const1+(user_d3:1*const1+user_d3:2*const2+user_d3:3*const4+user_d3:4*const8+user_d3:5*const16+user_d3:6*const32+user_d3:7*const64+user_d3:8*const128+user_d3:9*const256+user_d3:10*const512+user_d3:11*const1024+user_d3:12*const2048+user_d3:13*const4096+user_d3:14*const8192+user_d3:15*const16384+user_d3:16*const32768+user_d3:17*const65536+user_d3:18*const131072+user_d3:19*const262144+user_d3:20*const524288+user_d3:21*const1048576+user_d3:22*const2097152+user_d3:23*const4194304)/const8388608)

   The formula for the sensor parameter is created on the basis of the formula for converting to the 32-bit IEEE 754 format: F=(-1)S2(E-127)(1+M/223).
   

As a result, Wialon displays the values of the float sensor instead of user_d3=1017282565.

Example 3

Consider the case of the Teltonika FMT100 device when the io_258 parameter registers the values of the accelerometer on three axes when exceeding the values specified in the device. The data of this parameter is useful when working with the Eco Driving application. In Wialon, the data is registered as io_258=932034904003. The values should be converted into g.

The image below shows the parameter structure.

The values on the axes are signed. In Eco Driving, only the values on the X and Y axes are used. On the X-axis, depending on the sign, the acceleration and braking are determined. On the Y-axis, the transverse acceleration is determined which will be used as an absolute value (module) because the sign (left/right) is not taken into account in Eco Driving.

1. Create a custom sensor Accel_MAX in the unit properties in Wialon. In the Parameter field, specify the following formula :
   

   (((io_258:48*const32768)-(io_258:33*const1+io_258:34*const2+io_258:35*const4+io_258:36*const8+io_258:37*const16+io_258:38*const32+io_258:39*const64+io_258:40*const128+io_258:41*const256+io_258:42*const512+io_258:43*const1024+io_258:44*const2048+io_258:45*const4096+io_258:46*const8192+io_258:47*const16384))*io_258:48)/const1000

   
   

2. Create a custom sensor Brk_MAX. In the Parameter field, specify the following formula :
   

   ((-(io_258:33*const1+io_258:34*const2+io_258:35*const4+io_258:36*const8+io_258:37*const16+io_258:38*const32+io_258:39*const64+io_258:40*const128+io_258:41*const256+io_258:42*const512+io_258:43*const1024+io_258:44*const2048+io_258:45*const4096+io_258:46*const8192+io_258:47*const16384))*(io_258:48-const1))/const1000

   
   
   

   

   
   

3. Create a custom sensor Crn_MAX. In the Parameter field, specify the following formula:
   

   (-(io_258:17*const1+io_258:18*const2+io_258:19*const4+io_258:20*const8+io_258:21*const16+io_258:22*const32+io_258:23*const64+io_258:24*const128+io_258:25*const256+io_258:26*const512+io_258:27*const1024+io_258:28*const2048+io_258:29*const4096+io_258:30*const8192+io_258:31*const16384))*(io_258:32-const1))/const1000+(((io_258:32*const32768)-(io_258:17*const1+io_258:18*const2+io_258:19*const4+io_258:20*const8+io_258:21*const16+io_258:22*const32+io_258:23*const64+io_258:24*const128+io_258:25*const256+io_258:26*const512+io_258:27*const1024+io_258:28*const2048+io_258:29*const4096+io_258:30*const8192+io_258:31*const16384))*io_258:32)/const1000

   
   

   
   

   
   Two bytes are provided for the Y-axis. The bit numbers in Wialon are from 17 to 32. Since the module (absolute) values are taken into account, the formula is a little longer than the previous ones.

The given examples show that the application area of the bitwise control is not limited to the control of a specific bit. This is a comprehensive tool which allows creating custom sensors in Wialon. You can formulate the logic and calculation of such sensors on your own to fulfil the most challenging tasks.

• how to configure units which use the Teltonika GH5200 device so that you can monitor the physical distance between them during the COVID-19 pandemic;
• how to create notifications and register events about distance violations;
• how to create and execute reports in Wialon to analyze contacts between units and detect violations.

Configuring units

To configure units, follow the steps below.

1. In the device settings, open the Bluetooth Features section, enable the Proximity detection function and specify the required parameters.
   
   
2. Go to the Bluetooth 4.0 section and specify the required parameters.
   
3. Go to the Beacon List section and select Teltonika in the settings.
   
   
4. In Wialon, create a unit. On the General tab, type the name of the person who should maintain the specified distance. In the Unit type field, select Person. In the Device type field, specify Teltonika GH5200.
   
5. Go to the Sensors tab and create a sensor of the Passenger sensor type. In the Parameter field, specify io_875.
   
   
   
6. If necessary, create a custom sensor to determine the battery level. In the Parameter field, specify io_113. In the Unit of measurement field, specify %.
   
   
   

7. Go to the Custom fields tab and create a custom field named MAC address. In the Value field, specify the MAC address of the device used. 

   To find out the MAC address of the device, contact the hardware supplier. You can also find out the MAC address using messages in Wialon. The units determine the MAC addresses of the nearest devices of the same type and send them to Wialon as the io_875 parameter in messages. For example:
   io_875 = 439931433244443739334561.

   

8. Create the required number of units following steps 4—7.
9. Create a unit group and add to it the units the distance between which you want to monitor.
   
10. On the Passengers tab, create a passenger named as the unit which corresponds to it. In the Code field, specify the same MAC address of the device as in the custom field of the corresponding unit.
    

11. Create the required number of passengers.
    

    You should create a passenger for each unit specifying the same name and MAC address as for the unit to which this passenger corresponds.

12. Select all the passengers and create the list of automatic assignment to all the units to which they correspond.
    

The units are ready. Now you can configure notifications and create a report for them.

Creating notifications

To receive notifications and register events about distance violations, follow the steps below.

1. On the Notifications tab, create a notification for units which should maintain the specified distance.
   
   
2. Select the Passenger activity trigger type.
   
3. Enable the Check-in and Check-out options.
   
4. Select the Register event for unit action and enable the Register as violation option. To display the notification in Wialon, select the Display online notification in a popup window action as well.
   
5. In the notification text, add the %UNIT% and %TAG_NAME% tags. Type the required text between the tags. For example:
   
6. Specify the notification name and save it.
   

Now you can monitor the physical distance between the created units and register events in Wialon. 

Creating a report

To get detailed information on distance violations, create and execute a report on the unit group created in step 9. To do this, follow the steps below.

1. Create a report template of the Unit group type.
   
   
2. In the report template, create a table of the Violations type and select the following columns:
   
3. In the table settings, enable the Detalization and Total options.
   
4. Save the report template.
5. Execute a report on the required unit group using the created template.

Thanks to the executed report, you can not only get detailed information on distance violations but also reduce the risks of spreading the virus. For example, if one of the employees you monitor tests positive, you can determine when and with whom the infected person has been in contact recently. In addition, you can get this information by executing a report on passenger assignments.

• how to configure units in Wialon for automatic toll payment via the HU-GO system with the help of the e-track platform;
• what you should do to start transferring data from Wialon to e-track.

Configuring units

1. If you use Wialon Hosting, authorize to get an access token. The token is generated in the address bar after successful authorization. For example:
   
   If you use Wialon Local, follow the authorization link and replace hosting.wialon.com with your monitoring site address. For example:
   

   https://your.wialonlocal.site.com/login.html?client_id=hw_e_track_retranslator&access_type=-1&activation_time=0&duration=0&lang=en&flags=1&response_type=token

   Save the generated token because you should specify it in the email to your manager.

2. Open the properties of the unit for which you want to configure automatic toll payment (or create a new one).
   
   

3. Go to the Custom fields tab and add a custom field named e-Track_ObuId. In the Value field, specify the on-board unit ID (OBU ID) received after signing up for the e-track platform.
   

   All names are case sensitive and should be specified as given in the guide.

   

4. Go to the Sensors tab and click New. If an ignition sensor has already been created for the unit, skip this and the following step.
   
5. Specify the sensor name and select the Engine ignition sensor type. If the unit does not have an ignition sensor connected, specify speed in the Parameter field. If the ignition sensor is connected, specify the ignition parameter.
   
6. Go to the Profile tab. In the Registration plate field, specify the same number you entered when signing up for the HU-GO system. Click OK.
   
7. If you want to configure several units, repeat steps 2–6 for them.
8. Create a unit group and add to it units for which you want to configure automatic toll payment.
   
   
9. On the Custom fields tab, add a custom field named e-Track. Leave the Value field blank. Click OK.
   

If the IMEI, registration plate, or OBU ID values are changed in the properties of the unit added to the group, remove this unit from the group and add it again to take into account the changes.

Transferring data from Wialon to e-track

Messages with data from the units are transferred from Wialon to the e-track platform where the cost of toll roads is calculated on the basis of the received data and sent to HU-GO for automatic payment.

To start transferring data from Wialon to e-track, contact your personal manager or the Business Development Department (sales@gurtam.com).

In the email, specify the following data:

• name of the created unit group;
• registration plates of the units added to the group;
• name of the authorized user;
• token generated after the authorization;
• your monitoring site address in case of using Wialon Local.

• fuel level sensor (FLS);
• temperature sensor;
• engine ignition sensor.

Fuel level sensor

Before configuring the calculation table for the fuel level sensor, calibrate the fuel tank to get a table in which the values X correspond to the sensor readings, and the values Y, to the fuel volumes.

Below you can see two examples of the table configured using the XY pairs tool.

Example 1

Consider the case when you calibrate the fuel tank and get a table with the following data:

To configure the calculation table based on this data, follow the steps below.

1. Activate the XY pairs tool on the Calculation table tab in the fuel level sensor properties.
   
   
   
2. Add the required number of lines according to the values from the table obtained after the calibration of the fuel tank.
3. Specify 100 in the Upper bound field.
4. Activate the Apply after calculation option.
5. Click Generate.
6. If necessary, click on the icon  above the table to open the calculation chart.
   
   
   
   
7. Click OK.

Note. You can see how the coefficient a and the displacement b were calculated. The first interval starts with 0 and influences all input values up to 86. At the last point, the output value should be 10. First, the displacement along the X-axis was calculated: ∆Х = 86 − 0 = 86. The displacement along the Y-axis was calculated in the same way: ∆Y = 10 − 0 = 10. Then, using the formula a = ∆Y / ∆X, the coefficient a was calculated, which is the tangent of the angle at the beginning of the coordinate axes: a = 10 / 86 = 0,11627906976744186.

For other intervals, the same calculation formulas were used:

Example 2

Consider the case when you calibrate the fuel tank and get a table in which the input values X are indicated in descending order, and the output values Y, in ascending order:

To configure the calculation table based on this data, follow the steps below.

1. Activate the XY pairs tool on the Calculation table tab in the fuel level sensor properties.
   
   
   
2. Add the required number of lines according to the values from the table obtained after the calibration of the fuel tank.
   
3. Click Generate. After that, the indicated values Y are shown in descending order automatically.
4. If necessary, click on the icon above the table to open the calculation chart.
   
   
   
5. Click OK.

In this example, the table with formulas for calculating intervals looks as follows:

Temperature sensor

Before configuring the calculation table for the temperature sensor, find out what temperature the different values of the specified parameter correspond to. Consider the case when the parameter sends only positive values but some of them correspond to negative ones, that is, to the temperature below zero. For example:

• interval of positive values, from 0 to 127;
• interval of negative values, from 128 (which corresponds to −128 degrees) to 255 (which corresponds to −1 degree).

To configure the calculation table, follow these steps:

1. On the Calculation tab of the temperature sensor properties, add two lines and specify the required values as follows:
   
   
   
2. If necessary, click on the icon above the table to open the calculation chart.
   
   
   
3. Click OK.

Engine ignition sensor

Consider an example of configuring the calculation table for a non-digital engine ignition sensor, when the ignition activation is determined by the parameter transmitting voltage. For example, at a voltage up to 0,5 V, the ignition is turned off, and at a voltage over 0,5 V, the ignition is turned on.

To configure the calculation table, follow these steps:

1. On the Calculation tab of the engine ignition sensor properties, add two lines and specify the required values as follows:
   
   
   
2. If necessary, click on the icon above the table to open the calculation chart.
   
   
   
3. Click OK.
