CONTINUOUS NETWORK CONNECTIVITY WITH AUTO TOP-UP FEATURE

Introduction

Many transport businesses are regulated by governments worldwide. For example, lorries must be equipped with digital tachographs so that the data is sent according to a schedule; E-TOLL, modern toll collection solutions, are governed and electronically charged. Reporting is being digitised and made mandatory at the government level. Given this, measures should be put in place to facilitate the ease of data transfer and ensure its stability.

Solution description

As most transport and logistics companies are controlled by public authorities, fleet owners are required to submit digital tachograph charts regularly based on strict rules. Failure to submit data on time will inevitably result in heavy fines. According to the UK government website GOV.UK, the maximum fine for failing to do so can reach up to £10,000 and as much as 2-year imprisonment!

In the case of E-TOLL, a GPS tracker sends information on the location of a vehicle, the data is processed in the payment collection system, and a local National Revenue Administration automatically taxes the vehicle or fleet owners respectively. For example, if the data is not submitted on time in Poland, a car owner has to pay a fine, which starts at €300 per violation, as stated on the Ministry of Finance website etoll.gov.pl.

But what happens if the data is used up or the mobile network SIM card expires? Of course, the tracking device will be disconnected from the GSM network and no data will be sent at all.

Fortunately, Teltonika Telematics has a practical solution to help corporate fleets avoid such needless fines and ensure that the SIM cards of GPS trackers are always connected to the GSM network.

Every single Teltonika vehicle GPS tracker has a placeholder for a plastic (regular) SIM card or a possibility to install an eSIM module. The SIM card or eSIM is part of the Teltonika Global Connectivity Solution and is used to connect to mobile networks, and the GPS device will be able to send and receive data to and from locations covered by the data plan.

For example, the Teltonika Global Plan currently allows you to prevent roaming costs in 110 countries around the world and uses the same amount of data anywhere. But the fact is, any data plan has a limited number of megabytes, and if they are used up, a GPS tracker loses an access to the mobile network.

How it works - to keep SIM cards up and running continuously without physical and manual interference, we offer the convenient and practical Auto Top-Up feature. As the name implies, when properly set up, this function automatically renews the same data plan under the same conditions when the remaining amount of data has been used up to a specified limit. Thanks to it, fleet managers and business owners will not run into trouble if a SIM card plan data is nearly used up, or expiration term is around the corner but a person in charge has missed all the notifications, off duty, or simply forgot to top up the plan timely.

With the SIM card management IoT Platform, you can set up specific SIM cards to be topped up, choose notification rules (via email or SMS) when 90% or any other percentage of data is used up, or inform a person in charge that the last top-up has been depleted and there are no more of them left. As a result, there is no point to monitor the amount of data or the expiry date anymore, as automatic top-ups reduce the need for manual maintenance of the SIM cards, and fleet GPS trackers will always remain connected to the GSM network with no service interruptions.

What you need for a solution?

• Any FMx device
• The GLOBAL CONNECTIVITY SOLUTION SIM card in order to get data to your server
• IoT Platform to manage SIM cards.
  

Installation

It’s important to hide the tracker, so it would not be a simple task for the thieves to find and unplug it. But also, please do not forget to follow mounting recommendations as well (using the FMB130 device as an example).

Although devices have high gain antennas it’s important to mount devices with stickers on top and in metal-free space. The device should be firmly fixed to the surface or cables. Please make sure, that device is not fixed to heat emitting or moving parts.

The main solution in this case is the automatic charging of traffic in the IoT platform. If the Truphone SIM card is not installed from the factory, then install it yourself.

To have a working solution it’s important to properly wire the devices. In the picture below it's shown how to correctly wire the devices.

During installation please follow recommendations in order to avoid damaging device and vehicle:

• Wires should be connected while the module is not plugged in.
• Be sure that after the car computer falls asleep, power is still available on the chosen wire. Depending on the car, this may happen in a 5 to 30 minutes period.
• When the module is connected, be sure to measure the voltage again if it did not decrease.
• The ground wire is connected to the vehicle frame or metal parts that are fixed to the frame.
  

Configuration

2. Car sharing configuration:

Parameter ID – Parameter name GPRS settings:

• 2001 – APN
• 2002 – APN username (if there are no APN username, empty field should be left)
• 2003 – APN password (if there are no APN password, empty field should be left)

Server settings:

• 2004 – Domain
• 2005 – Port
• 2006 – Data sending protocol (0 – TCP, 1 – UDP)

After successful GPRS/SERVER settings configuration, FMB130 device will synchronize time and update records to the configured server. Time intervals and default I/O elements can be changed by using Teltonika Configurator or SMS parameters.

Sleep settings:

• 102 – Sleep settings(0 – Disable, 1 – Gps sleep, 2 – Deep sleep, 3 – Online Deep sleep, 4 – Ultra sleep)

Note: This scenario will not work with Deep Sleep and Ultra Sleep modes, since they disable the device's GSM module to save power.

Can adapter settings:

• 45002 – CAN Adapter program number (This code is written in every connection diagram and it is specific for every vehicle model and make year)

• 45170 – Door status, Priority "Low" (0 – Disabled 1 – Low 2 – High 3 – Panic )

• 45130 – Fuel level, Priority "Low" (0 – Disabled 1 – Low 2 – High 3 – Panic )

• 45220 – Total milage (Counted), Priority "Low" (0 – Disabled 1 – Low 2 – High 3 – Panic )

• 45430 – Security State Flags, Priority "Low" (0 – Disabled 1 – Low 2 – High 3 – Panic )

Quickstart: From default configuration to Car sharing solution in one SMS:

"  setparam 2001:APN;2002:APN_user;2003:APN_password;2004:Domain;2005:Port;2006:0;102:3;45002:ProgramNumber;45170:1;45130:1;45220:1;45430:1"

This SMS will set up your device to report the Car Sharing scenario to the server and the possibility for remote control of vehicle components.

Note: Before SMS text, two space symbols should be inserted if no SMS username or password was set in SMS \ Call settings.

• 2) Unlocked doors 00 80 00 00 00 00 00 05

Convert HEX value to BIN value:

Then count 28'th BIT from the back (28'th bit value shows locked/unlocked states)

• 1) 10000000000000000000000000110000000000000000000000000101

If car is locked value is 1 and if car is unlocked value is 0

To test the car unlocking and locking use these GPRS commands

• 1) To unlock all doors use this command: "lvcanopenalldoors"
• 2) To lock all doors use this command: "lvcanclosealldoors"
