Introduction:
-
This system is ideal for owners of fleets of trucks
or busses who would like to keep track of the
locations of their vehicles at anytime.
-
It is an aid to Logistics & Supply chain management
and increases the efficiency of warehouse management
and vehicle management systems. It allows vehicle
owners to keep tabs on their vehicles and goods, and
also acts as a deterrent to drivers engaging in
untoward activities.

Web
Based |
|
|
| The
Web Based AVTS application software does not require the
installation of client software in clients’ PCs at
client end. The vehicle AVTS unit communicates with a
Web service hosted on the Web server via SMS or GPRS to
update position data on database server (MSSQL/MS
Access). Clients simply have to subscribe to Web service
and log on to Web server via the Internet to access
vehicle data on database server, and view latest vehicle
positions on map. |
|
|
|
Server-Client
Based |
|
|
The
Server-Client Based AVTS application software requires
the installation of client software in clients’ PCs for
vehicle data download from server. Client logs in to
client software using a valid username and password to
download vehicle data stored in central database
maintained by Local or Web server for monitoring and
analysis purposes.
The GSM modem receives data from vehicle AVTS
units via SMS or GPRS and the data is then stored at
Local or Web server. The central database contains all
vehicle data stored in different databases, i.e. vehicle
regular interval position report/activity report data,
over-speed report data, SOS report data, barcode report
data, vehicle configuration data, Point of Interest
(POI) report data, geo fencing violation report data and
route violation report data. Individual user is able to
view only the vehicle data which he/she is allowed to
view, depending on the user rights assigned to
individual user by the administrator. The software
administrator has the rights to view all vehicle data as
well as remotely configure hardware units. The GSM modem
can also send outgoing configuration messages to AVTS
hardware units installed in vehicles via SMS or GPRS.
Apart from requiring the installation of client
software at client end, every PC with client software
installed needs to have applicable map imported for
vehicle locations tracking or viewing. |
