Telemechanical control unit MTK - 30.CU
The use
The CU is software and hardware complex that is used for telemetric data processing transfer and receiving from telecontrol devices of a Controlled Unit.
The CU fields of use:
- The Automated Dispatching Control Systems ( ADCS):
- As a telecontrol lines data collection device;
- Corporate systems:
- As an information HUB for technological, operative and commercial information receiving and transfer.
The CU is a functionally independent part of “SYSTEL” Program-Technical Complex (PTC)
Functions
- Data receiving / transfer by different connection lines:
- Simultaneously by several independent lines;
- Using line adaptor on 16 full duplex or semi duplex connection lines.
- Using RS-232 (one or two):
- protocol ГОСТ Р МЭК 870-5-101-2001;
- Using Ethernet:
- protocol ГОСТ Р МЭК 60870-5-104-2004,
- Protocol SystelNet – internal protocol PTC «Systel» on the TCP/IP basis.
- Preliminary data processing on dispatching unit.
- Received data transfer to OIC for processing and display.
- Data retranslation:
- to CRTS, ТМ Server;
- To the lower and adjacent dispatching control levels.
- Formation of (if necessary):
- measurements archives
- Events protocols
- Providing interlevel data exchange:
- With other CUs – using different TM protocols, including protocols that comply with ГОСТ Р МЭК 870-5-101-2001 and ГОСТ Р МЭК 60870-5-104-2004.
- With OIC – using protocol ГОСТ Р МЭК 60870-5-104, РПТ-ЭВМ and SystelNet.
Data sources
- Telecontrol devices, installed on the controlled units (CU);
- Other CUs , installed on the dispatching points.
Software
The device software functions under Linux operative system control and consists of the following basic components:
- The “Real-Time Monitor” program complex.
- The in-built WEB-server for monitoring and diagnostics purposes.
- WEB-АРМ telemechanics.
- The CU device software includes the starting initialization programs.
- The CU device software includes the tools for CU configurational data creation and modification.
External connections
- 16 Current Telemetric Lines (CTL) from metric converters with fixed output current range of ±5 мА or ±20 мА,
- More lines are available;
- 16 discrete signal lines (ТС),
- More lines are available;
- 4-х проводные магистральные линии связи, к которым подключаются КП;
- 4 hard wire type trunk lines , to which a CU is connected
- RS-232 interfaces with galvanic interfaces.
