General description

The implementation of such system helps the automobile operating company to solve following issues:

• The monitoring of the deviation from the route by the automotive transport;
• Receiving of almost any kind of data about the automotive transport means in any place of Europe directly from the office;
• Calculation of the optimal route, definition of the kilometrage with the help of map, calculation of routing time of the truck-train, required fuel consumption and other necessary information;
• the possibility to of output of the route as the text document with mentioning traffic checkpoints, distance, geographical coordinates, and the direction of the traffic (it is convenient for the drivers).

Work process of the system:

Satellite modem defines the coordinates of its location and waits for the defined time of sending the message, transfers the information about its location in the space, about its condition and the state of the detectors connected to it, as well as the information about the power.

Via the satellite the information is transferred to the landline station, where it is processed and with the help of e-mail is transferred to the Datagroup server, where it is converted into data format, with which the software «Transport Means Controller» (TMС) is operating. All the information is saved in the central base on the Datagroup server, so that if for some reasons the client could not receive it (due to the absence of connection to the Internet, technical problems of because the server of the client was just switched off), then as soon as the work of the equipment of the client will be restarted, then all the information that concerns this client will be transferred to him within several minutes (the time depends on how long ago the last synchronization with the Datagroup server was performed).

The time of synchronization with the central base depends on the chosen time interval of sending the information by the satellite modem (5, 15, 60, 180 min.), and also on whether the client is going to use the option of position request, if yes, then it will be 5—10 min.

The scheme of the work process of satellite system of monitoring and traffic control for the moving objects can be seen.

Software for traffic control center

Possibilities:

• the traffic control of transport means (monitoring, location and state)
• preparing of the traffic schedule of the transport mean within the planned trip
• planning of the possible routes, as well as the routes within the planned trip.
• Registration of new clients in the system, that helps to form the requisitions for goods delivery and to control its fulfilment
• Traffic analysis within the trip (round trip)
• The possibility of web-control of the traffic of transport means by the client

Equipment

The equipment produced by our partner, SpaceChecker company, is used (it is one of European leaders on the market of satellite tracking, monitoring and management systems), satellite terminals with the modification SC100 and SC200. As the manufacturing of the modems SC100 is already stopped, only its comparing characteristics is given in this description to enable you to see the difference between its modern modification SC200.
