Tracking System GPS
The DTS-4 (Data Tracking System) is a safety and satellite localisation system in GPRS/GSM with 4 inputs with an integrated GPS. The specially designed system has been created in an efficient and efficacious manner for the protection of all mobile vehicles (as single units or fleets). All the itineraries traversed and all the events affecting the vehicle can be saved in an incorporated memory file, together with the time and location. The peripheral unit is energised by the vehicle battery and also has automatic power saving functions.
The GPRS system
By adopting the mobile GPRS system, the DTS-4 guarantees instantaneous notification and reduced operating costs (depending on the quantity of data actually transmitted) with the possibility of using M2M-type SIMs that do not envisage any concession tax or actual monthly rentals.
Backup information in SMS format
The DTS-4 device uses the GPRS channel as its primary transmission system: in the event of unavailability of this carrier, the notifications can be sent by text messages in SMS format.
Reduced overall dimensions
A complete and complex design study together with painstaking research and integration of the components have allowed to minimise the size, facilitating installation on any type of vehicle needing to be monitored (cars, trucks, motor-homes, motorbikes, boats, motor-yachts, etc.).
The DTX-4 unit has 4 inputs for external interfacing. These inputs can be logic, configurable either as “general” or “specific” functions (e.g. vehicle starter key, wired-type emergency pushbutton, door opening, enabling/disabling of an existing antiintrusion system), with one analogue input (for checking values like temperature etc.)
Virtual input channels
The DTS-4 unit has 8 additional “virtual” input channels for constant monitoring of the peripheral unit; the itineraries and events detected are always stored in the memory file of the DTS-4 unit together with the date and time, and can be transmitted to the Operating Centre. This system also enables automatic management of the following:
- Parking status, which represents the first reduced consumption stage and turns off the GPS on the DTS-4 unit. It can be activated for short periods of inactivity (settable from 1 to 255 minutes).
- Garage status, which represents the second consumption stage. It turns off the GPS and the GPRS communicator and can be activated for long periods of time (settable from 1 to 255 minutes).
- Exceeding of set distance: transmission of the location where a set distance is exceeded. This can be set between a minimum of 100 m and a maximum of 25 km.
- Slowing down for a certain period: transmission of the location of the DTS unit in case of a drop in speed below the set parameters causes the DTS unit to transmit the position (the value “0” indicates that the vehicle has stopped).
- Speeding: transmission of the position whenever the set speed value is exceeded (from 0 to 300 km/h).
- Aggression and rescue: besides the possibility of connecting a wired-type anti-aggression control, the DTS-4 unit is also equipped with a 433MHz receiver and a remote control unit. Simply by pressing a button the request for help will be activated indicating the position of the vehicle. The rescue notification can also be sent thanks to the recognition of calls coming from 2 numbers set as desired. Once the numbers have been recognized, the DTS-4 unit automatically forwards the call (only with Vodafone SIMs).
- Obscuring of the GPS signal: whenever the GPS signal is obscured for a certain period of time (settable from 1 to 255 minutes) an alarm notification will be transmitted.
- Remote control unit battery flat: the DTS-4 unit is capable of transmitting information regarding the battery level of a remote control unit for forwarding aggression/rescue requests (only if RFM).
The DTX-4 unit also has 4 outputs that can be general (static or impulsive), or specific, meaning they can carry out special procedures such as activation of privacy function, sending commands via radio pushbutton (optional) or by mobile telephone with a set number.
Besides sending information pertaining to the inputs and outputs, the DTX-4 unit can also be set to transmit survival notifications at preset times, indicating the status of the connected channels and the location of the vehicle. Thanks to automatic checks, this procedure allows the Operating Centre to continuously monitor the perfect efficiency of the systems. The time interval between the spontaneous tests can be set for a minimum of 1 hour and a maximum of 255 hours, with a distinction between the OF and OFF status of the vehicle.
The privacy function allows for disabling the notification and saving the user’s location. It can be activated during the programming phase or by using an internal switch or a command from a mobile phone, or from the Operating Centre. Whenever this option is activated the data relating to the movements of the vehicle are not disclosed. The DTS-4 unit can transmit to all the channels set without indicating the information regarding location, however in the case of interrogation, it can only notify the status of the channels connected. Aggression and rescue events, as well as emergency alarms on the wired input are excluded from the privacy function and their current location will also be transmitted.
Use of text messages
Apart from the alarm communications sent to an Operating Centre in GPRS, the DTS-4 unit can also send brief text messages in SMS format (Short Message System) to 2 preset telephone numbers. These messages only contain information concerning the status of all the input channels (real or virtual). It is also possible to use a mobile phone to activate the commands and obtain information directly from the DTS-4 peripheral unit (such as privacy, geographical localisation of the vehicle, command of an output, passing over to energy savings). This can be carried out by using predefined texts recorded during the programming phase and protected by suitable passwords.
Event memory file
The DTS-4 unit can record all the events in its own memory file (such as variations in the inputs, activation of outputs, vehicle battery level, energy savings, exceeding distance, slowing down, speeding, aggression/rescue, obscuring of GPS, absence of GPRS) indicating the relative dates and times, geographic data (expressed in longitude and latitude), and a brief description. A maximum of 1,500 events can be saved (and overwritten once the file is full). The event memory file can be viewed locally, from a portable PC, or in remote mode through the GSM network.
Local or remote programming
The operating parameters can be set on the DTS-4 unit in a simple and intuitive manner from the SICEP MVC software for PCs that allows for viewing and modifying the parameters from Windows-style graphic pages. These can be stored and reloaded by files on the PC in order to create a basic personalised programming. The device allows for performing these operations either locally or in remote connection by exploiting the GSM network.
During the programming phase it is possible to use two diagnosticpages that are useful for checking the parameters of the GPS and GPRS operation and carrying out connection tests on the various communication carriers (GPRS and SMS).
