TELEMECHANICS
Software and technical tools (PTS)
As a PTS for the creation of automated systems and telemechanical complexes, we use domestic equipment and software both of our own development and of the foreign company ABB, of which we are official partners.
The basis of the aircraft-level complexes is the Multi-channel Collection and Management Controller (BKZU, TU U 31.2-25641912-001:2011), which provides full-scale data collection on electrical parameters on the aircraft and the transmission of teleinformation to the local and upper level of dispatching control. In the reverse direction, the BKZU relays discrete remote control commands of high-voltage switching equipment.
Built-in application software BCZU functions on the platform of the Linux real-time operating system and provides support for a series of data exchange protocols of international standards, such as:
- Modbus RTU Serial (Master/Slave);
- Modbus RTU TCP/IP (Master/Slave);
- IEC60870-5-101(Master/Slave);
- IEC60870-5-103(Master/Slave);
- IEC60870-5-104(Master/Slave);
- IEC61850-8 MMS (Master/Slave);
In addition, it supports exchange on a number of specialized protocols such as:
- AIST
- GRANIT (PU)
- KOMPAS (PU)
- TM120 (PU),
- MKT-3 (PU),
- MKT-2 (PU),
- TM-512,
- SPA (ABB company)
- GPS time
- NTP server/client
- SNMP
- WEB SCADA with TLS
- PLC functions aka IEC 61131
- 2GPIO channels
Configuration of built-in software for specific operating conditions is carried out remotely over a computer network using service software.
Communication with service personnel during repair and preventive works is supported via the WEB interface using a connected technological computer. Hardware BKZU is delivered in the form of a cabinet with modules mounted in it and a group of remote autonomous blocks for building a decentralized structure of the telemechanics complex.
Cabinet of telemechanics BKZU with electronic modules of custom configuration in floor or wall design
IP54 metal cabinet with electronic modules mounted on DIN rails. The operating temperature range is minus 20 to 50°C. The composition of the modules, in various quantities and ratios, may include:
— KPL32. The controller programmable logic based on the VDX-6358RD type industrial controller with installed Linux OS and built-in application software. Number of dedicated digital channels with RS-232 interface, 4, 8, 12. Network with Ethernet interface, 1 or 2 (can be used independly);
— MPDS-32M Modbus RTU module for inputting discrete signals of the «dry contact» type on 32 channels (can be used independly);
— BTU-32M Modbus RTU remote control unit for 32 two-position channels (5A; ~/=220 V) (can be used independly);
— AKON. Modbus RTU module for inputting analog signals of normalized current (0…5 or 4…20 mA) (can be used independly);
— MP-RS232/485-8k multiport module for converting the RS-232 interface into RS-485 with group galvanic isolation by means of 8 radial channels (can be used independly);
-MSAC. GPS system astronomical time synchronization module;
-PS. Mean Well power supply unit without backup and with backup from
batteries of the type DR 45-24 or AD 55B (with two batteries). Input power 220 V AC or DC.
