AutoGRAPH-GSM/SL controllers installed
on vehicles constantly receive coded signals
from Global Positioning System (NAVSTAR)
and GLONASS satellites. These signals are
used to determine exact coordinates of the
vehicle location.
The coordinates are written to the nonvolatile memory of the AutoGRAPH-GSM/
SL controller, either on a regular basis or
adaptively. Furthermore, the storage memory
records and stores the statuses of various
sensors connected to the tracker or data
buses, and other parameters required by the
software.
Either on a regular basis or upon occurrence
of a preset event, the collected data is
transferred to the dedicated AutoGRAPH
server over the Internet using General Packet
Radio Service (GPRS) supported by a GSM
mobile network operator.
The server is a computer running Microsoft
Windows Server or Linux/FreeBSD with an
Internet connection, permanent IP-address
and reliable data storage device. The
server is responsible for receiving data from
AutoGRAPH-GSM/SL controllers, storing
the data and transmission upon request to
the dispatcher stations. Key les are used to
provide data access security on the server.
Dispatcher workstations are personal
computers or laptops with the AutoGRAPH
dispatch software installed (and with the
key les required for particular vehicles)
that has either Internet access or server
connection via LAN. An Internet connection
and computer with the Dispatch Software
will enable users to obtain data from
anywhere in the world. Easy deployment of
the Dispatch Software without the need to
install third-party database support enables
users to immediately create new dispatcher
workstations with any PC running MS
Windows 2000/XP/Vista/7/8. The number
of workstations is unlimited. The Dispatch
Software is completely free of charge and the
latest version may be downloaded from the
ofcial website of TechnoKom: http://www.
tk-chel.ru.
Mobile users can easily track vehicle
movement in real-time using WEB based
AutoGRAPH.WEB Dispatch Software run on
any mobile device connected to the Internet.
Upon the user’s request or on a regular basis
the dispatcher workstation connects to the
server to update data on vehicles. Depending
on the AutoGRAPH server software version,
access to the data is offered by means
of the key les stored in the dispatcher
workstation or using personal login and
password. The received data is stored in a
local folder on the dispatcher workstation
that enables processing of the data without
being connected to the server. Furthermore,
to reduce the web trafc, the dispatching
network may be organized in such a way as
to send any missing data through the Internet
to only one workstation, while all other users
may use these downloaded data via LAN
by retrieving them from the local data folder
of the workstation. The users may use this
data to track the vehicles on a map, browse
through various parameters, events and
readings of various sensors. In addition, it is
possible to generate various types of reports
and charts both for each particular vehicle
and in groups.
To interact with various external applications
and handlers (including 1С), the AutoGRAPH
Software incorporates OLE server application
(COM server) which enables data exchange
between the AutoGRAPH Software and the
programs written in the majority of existing
programming languages which support OLEenabled data exchange, as well as programs
and systems based on their own embedded
programming language (1С Enterprise, MS
Ofce, various databases, etc.). Furthermore,
there is an option to upload all tracking data
and reports in the form of MS Excel, DBF
and CSV les, as well as to use an external
customizable reporting module which allows
users not only to generate a large number of
reports with fully customized layout, data and
