The invention
- The problem to be solved:
The separate tasks of supplying power and providing commands are resolved by an energetic
method without loading the line.
|
- Definition:
The frequency of the AC power source changes in an adjustable way. There is a filter tuned
to a certain specified frequency in the independent user units connected to a line shared
with the AC power source. One of the independent user units is supplied with power when
the filter tuned to a certain specified frequency passes the power of the AC source
operating on the same frequency.
|
- Presentation:
The frequency of the AC power source is determined by the value setting unit,
which is a potentiometer in the simplest case.
The input of the AC power source is the 230 V AC mains.
The output of the AC power source is the changing frequency "Uf" output, which
is connected to the two-wire power supply and communication line.
Through the inputs of their filters, the independent user units are connected to the line.
When the filters pass the power, the operation of the electronics coupled to the output is
enabled.
|
- Application:
Controlled and/or regulated drive of DC motors sharing a common line.
Measuring data acquisition at a retrieval rate of approx. 500 measuring points / sec.
Video surveillance system.
Area, property and site protection.
Environment protection and nature conservation monitoring.
Various applications in noisy industrial environments.
|
- Advantages:
The line is burdened by the current of one unit only at a time.
High interference protection due to AMPER magnitude operations.
Various kinds of applications are possible.
Suitable for both manual and computerised operations.
|
- Stage of development:
The operation is proven by circuit simulation on a component and system level.
The model that demonstrates the operation is ready.
Designing the circuitry of the system is in progress.
