System
package:
1.
Digital controller – 6 channels; for operation with digital electrometer.
2. Radio modem specialized with scrambled protocol – ÍÌ-18.
3. Software for receiving and archiving the information
given by the electrometers.
4. Electricity supplying block.
5. Laptop.
The
data is stored under hour, date,
subscriber's number, electrometer's number and rate.
With this system not only panels in hard to access places can be operated
but normally mounted panels as well.
Through the laptop and an automobile the accounts of the electrical panels
equiped with digital electrometers, digital controllers and radio modems can
be rendered.
In the future it is possible, if a radio network is present, the data from
the electrical panels to be sent directly to the electricity supply company. |
The
system is developed by Technopol -
Stara Zagora on the basis of given by “Energorazpredelenie”
- Stara Zagora, branch Sliven electrometer type: KRIZIK - EJS210-D1AAM and
allows for remote measuring of the consumed electrical energy from digital
electrometers mounted in panels in hard of access places.

Features
of the system:
1.
Transmits the data from the electric panel to a laptop via low-powered radio
modems at distances from 100 to 500 m.
2. Simultaneous measuring of six electrometers using one
controller.
3. Allows for automatic switching between different rates
from the controller.
4. Allows for remote setting of the controller's clock
at each connection to the laptop.
5. Allows for remote switching on\off of the consumer of
each electrometer separately.
6. Connection by special hoping radio modems in ISM band
at distance from 100 to 500 meters.
Operation
principle of the system:
The laptop is used for starting the remote measuring software. It is accepted
that the readings of the counters of the electrometers
and the software are originally entered and equalized. For each measuring
the following is necessary:
Approach the electrometers panels with the laptop. Start the software and
connection through the radio modems HM-18 is made. The devices check the
quality of the radio connection and if it is good allow radio contact between
the controller in the electrical panel and the laptop. The software will
receive and archive only data from the electrometers for which radio contact
is allowed. First the controller's clock is synchronized with the one in
the laptop and then the radio contact is made. After confirmation of the
correct receiving of the data from the controller the radio contact is suspended.
