Modularized Electrical Control System
Modularized Electrical Control System
Performance
This system mainly consists of the main controller module, analog data acquisition module, signal isolation module, communication isolation module, remote control receiver module and display module, etc.
The hardware part takes the single-chip microcomputer as measuring control core, integrating CAN controller and an array of analog and digital modules, each of which adopt the same microprocessor to improve the consistency of the system as well as simplify the system design.
The software uses reliable communication mechanism to meet the controlling requirements of high reliability. Programmers for analog acquisition, digital signal collection, SCM and PLC, as well as inverter communication procedures etc. are available.
Configuration software is used for programming to control the configuration.
Analog data acquisition module carries out functions as high accuracy measurement of current and temperature, encoding and data transmission.
The control module can set the shearer in either remote control or local control.
The communication interface module enables possible the data exchanges among PLC, inverter and CAN bus.
Efficient anti-interference measures are taken in the monitoring system.
It is proved in the field operation that the system demonstrates excellent performance characteristics as high stability, good real-time, simple construction and easy maintenance.
