Professional Telematic Alarm

We have been working with transport companies in the Automotive Telematic branch for several years and certainly we can tell we understand the problems of our customers. To solve the main ones we have created an innovative device: a hybrid of a car alarm and a telematics device, which is intended for use in semi-trailers and truck trailers. What is the outcome? Security and access to a number of crucial information obtained from semi-trailers ensure an unprecedented level of support and safety of the supply chain.

Based on the knowledge gained during several years of work with devices mounted on semi-trailers, we have decided to focus on a premium class solution. The highest quality components will cope even with extremely unfavorable working conditions. Advanced alarm and logistics system will meet the expectations of the most demanding users.

Basic description

Professional Telematic Alarm (PTA) is a homologated device designed for installation in truck trailers. Regardless of the state of the main power supply, the terminal continuously performs two most important functions:

Anti-theft protection of the vehicle and the transported cargo, e.g.: *
- alarm arming/disarming control,
- control of connecting/uncoupling the tractor to the semi-trailer,
- control of the movement of the semi-trailer with the tractor disconnected,
- monitoring the opening of the cargo space,
- control of the fuel filler in the cooling tank,
- checking the opening of cargo boxes.

In the event of a violation, the alarm siren is being activated and the appropriate information is sent via GSM network.

* Depending on the type of additional security devices installed (e.g. opening sensors, motion sensors, digital seals and customs cords).

Supporting logistics processes through access to a lot of information obtained from the vehicle, e.g.:*
- geolocation of journeys and stops,
- vehicle speed,
- information about incidents, e.g. opening the loading door, disconnecting the tractor, opening the loading boxes,
- control of engine working hours (e.g. cooling unit),
- temperature control in the cargo space,
- VIN number,
- status of the semi-trailer counter,
- axle loads.

* Tools supporting logistics processes depending on the functionality of the application which downloads information from the PTA terminal.

Maintaining the continuity of the PTA terminal operation is possible thanks to the design of the proprietary buffer power supply system. It enables correct operation of both the terminal and additional safety devices (complete semi-trailer protection system) with the semi-trailer disconnected from the tractor.

The information obtained by the PTA terminal is transferred via the GSM network directly to the end user (via SMS with a limited amount of information). Also by using a full, open communication protocol, information is transferssed to the indicated address of the server receiving and processing the obtained data (Internet transmission of the GSM network).

The PTA kit includes:

Main board of the central unit designed from scratch by our engineers, performing most of the functions necessary in the security and logistics process.
Add-on expansion module board with specialized add-on functions to quickly adapt the PTA to individual, non-standard deployments.
Aluminum, hermetic, reinforced housing that meets the necessary requirements for proper operation of electronics in extremely unfavorable conditions outside the semi-trailers.
Specialized industrial connectors, external GPS/GSM antennas and a hermetic alarm siren built into the body of the housing guarantee a tight and durable monolithic construction.
Connection bundles secured with polyamide conduits terminated with screw plugs, enabling efficient installation in the vehicle.
Keyfob controlling the alarm functions of the terminal.

Alarm functions

Sound notifications of alarm status (e.g. armed, disarmed, line violation, service status).
The sound signal after detecting an alarm incident lasts 30 seconds and turns off. Optionally, you can program the number of repetitions of the sound signal.
Arming the alarm via the keyfob or sending an SMS.
Remote arming:

- After the first activation, the alarm is armed immediately, informing about the correct arming with a sound signal.
- If one of the alarm lines is violated (input C_01 or C_02 in a high state: e.g. opened loading door), the alarm will not be armed, informing about this event with a sound signal - the so-called failed attempt to arm the alarm.
- It is possible to activate an alarm when the alarm line is violated. The alarm should be reactivated within 6 seconds of the audible information about the failed arming attempt (e.g. arming the alarm with the loading door open).

Re-arming of the alarm after being accidentally disarmied. If the alarm has been disarmed and there is no change in the status of the alarm inputs for 10 minutes (e.g. opening the loading door, disconnecting the tractor), the alarm will be armed again, confirming it with a sound signal.
Programmable auto-arming function. After the alarm has been disarmed, it will be re-armed after the programmed delay time (not less than 10 minutes from disarming).
If, after the programmed delay time (10 minutes by default), the terminal detects a high state on the C_01 or C_02 input line (e.g. opened loading door), the alarm will be armed without these signals.
If the C_01 or C_02 input lines change their state to low, the alarm will arm the previously inactive line after 5 minutes (so-called alarm rearming).
Programmable Panic Button or Silent Alarm function. Holding the button on the keyfob for 5 seconds activates one of the selected functions:
- Panic Button turns on the alarm siren for 30 seconds and sends alarm information according to the programmed rules.
- Silent Alarm sends alarm information according to the programmed rules (the siren is not activated).

Both functions do not change the logical state of arming/disarming the alarm.

SMS and Voice Call notifications

The terminal enables programming of four mobile numbers, which will be receiving SMS about the generated alarm states along with the location of the transmitting terminal - Google maps link.

After activating the SMS, the Voice Call function starts - the terminal will call a defined mobile numer.

Broadcast configuration (sending records with information to the target server)

All information obtained by the PTA terminal is transmitted using the GSM network (data transmission based on public or private encryption). This is done using a full, open communication protocol. All information acquired by the terminal at a given moment is sent to the indicated address of the server that receives and processes data. Thanks to this, the PTA terminal enables integration with any IT system, ensuring the receipt of all data described in the protocol. Recording can be done in several ways.

Basic parameterization.
The basic configuration of sending records has been divided into three groups. Different parameters are programmable for each of them:
- Ignition switched on:
  - elapsed time since the last frame sent (second interval),
  - distance traveled (meter interval),
  - twist greater than XX degrees (turn angle interval).
- Ignition switched off:
  - elapsed time since the last sent frame (second interval).
- No main power:
  - elapsed time since the last sent frame (second interval).

Advanced, asynchronous parameterization.
- Incident record. Changes in the status of inputs or outputs of groups C, P, M and W each time generate a record with information about events, regardless of the status of the ignition switch and main power supply.
- RPM record (engine speed). Optionally, detection or loss of engine rotation generates sending information to the server.
- Temperature record. When performing temperature measurement, independent parameterization of sending records is available (programmable minimum time of sending information to the server).
- Battery safety record. After detecting a critical condition of the emergency power supply battery, the terminal can disable all alarm and transmitting functions by going into hibernation and transmitting a record in a defined time interval.

Configuration of terminal functions

Changing individual parameters is possible by:

Local configuration using the service program by connecting a cable to the terminal.
Remote configuration via dedicated SMS commands.
