EKV'
OPERATION
Before starting the engine the driver inserts his card into the reader
of the EKV unit. When starting the engine the system established. On the
display of the EKV unit information is shown that is being recorded on
the card:
- card ownership
- available space
on card
- travelled distance
from last emptying
The system is established
after starting the engine. The reader checks the authenticity of card,
if card is not suitable a sound signal is emitted that works all the time
the car engine is running.
GPS module starts
searching for satellites. During the search for satellites the display
emits the message "Please wait ". When the GPS gives the coordinates,
the time and current position (information about beginning of trip) is
recorded in the memory and card. During the trip the display shows information
about travelled distance, current position or just a kind message such
as: "Safe trip" or "We wish you a nice day ". Such
an uplifting message has a positive effect on the driver no matter how
many times he has seen it.
During the trip the information about travelled route (km, time, route)
is recorded on the driver's smart
card and memory that is installed in the EKV with the aid of the
GPS system. Setting the value of sampling distance is at choice, the card
can record more than 2000 km of travelled distances. The frequency of
recordings can be increased, which causes a decrease in accuracy of measurement
of travelled route.
If the GPS loses the satellite signal during the trip the display flashes
a warning "Please wait" that stays visible until the satellites
are found again (travelling through gorges, tunnels…). When turning
of the car the system automatically records the time and coordinates (information
about conclusion of trip).
All information that is recorded on smart cards is also stored in the
memory unit. It can record information for 32.000 km or 64.000 km (depending
on the size of the memory and setting of sampling distance). The recorded
data can be read, saved or deleted with the aid of a portable computer
and service card. In the event that the memory unit is completely full
(intervals of emptying are too long) new information is recorded over
the initial data (cyclical recording).
After travelled route it is necessary to transfer all recorded data into
the control system of organisation with the aid of the user's card. An
authorised person checks it, stores it appropriately or uses it for the
purpose for which it was collected.
The system also enables basic checking of the route distance beside precise
control of travelled distance that is recorded in two formats:
- As route on the
map, which requires entering the map of the whole area into the system.
- As relation base
where accurate data about travelled relation is gathered in register.
Because of the use
of the GPS system each point in space is defined by two variables; latitude
and longitude. The program enables naming any number of locations - points,
which is an aid when controlling trips. Naming is suitable for all locations
where a driver (service person) appears more often ex: home, client X,
company outlet.
After transferring
all this data the system operator (administrator) deletes the data saved
on the smart card. Before reusing
it the necessary data about driver and sample distance of recording should
be entered on the card. With this the card is prepared for the next use.
For the archive we
can save all travelled routes locally on the computer's hard drive or
we print them out.
