Microprocessor control and diagnostics system - MSKD
System purpose
MSKD system performs automatic control of the traction drive and electrical equipment, and also ensures monitoring of the parameters and technical condition of the systems, components, and assemblies of the locomotive
System ensures
- Reading analog and discrete input signals used for algorithm operation
- Information exchange with the locomotive units via digital CAN buses for algorithm operation
- Equipment control of the locomotive using algorithms, with discrete output signals
- Monitoring and detection of deviations in the operation of the locomotive equipment (exceeding critical and limit values of controlled parameters)
- Displaying on the screen of the onboard computer the data received from the locomotive devices in graphical and numerical formats and as emergency alerts with storage
- Recording information in the non-volatile memory of the onboard computer
- Connecting an external electronic storage device for reading data recorded in memory, for further decoding and archiving at the depot
- Internal diagnostics of its components with test results displayed on the screen
- Control of engine start/stop according to the algorithm agreed upon with the customer and engine manufacturer
- Operation control of the motor-compressor, using the pressure data of the supply line of the diesel locomotive
- Operation control excitation schemes of the auxiliary generator
- Operation management of the cooling system, including opening/closing blinds and turning the fan motor on/off
- Management of sanders of the locomotive
- Management and manual reset of the protection relay for the power transmission system
Structure
MSKD is built on a modular principle
System components: BRUEP, BUSI, KB, parameter sensors
01.
KB
On-board computer
Touchscreen panel computer with software for information display
02.
BRUEP
Power transmission regulation and control unit
BRUEP is designed to provide regulatory control over the power transmission by managing the excitation current of the traction generator
The unit receives signals from parameter sensors of the traction generator and traction motors, and sends signals to the power control equipment of the diesel locomotive
03.
BUSI
Control and information collection unit
Monitors and displays on the system unit's screen information about the state of the electrical transmission, main and auxiliary equipment of the diesel locomotive, as well as the status of discrete signals from the electrical system's actuators
In addition, it generates alarm and warning messages, which are used from the archive for quality maintenance of the diesel locomotive.
