1. Introduction to the Fully Digital DC Electric Control System
This product is a fully digital DC electric control system, specially designed for industrial automation control, particularly suitable for precise control of heavy equipment such as mine hoists.
1. System Composition
Operator Console and Host Computer: Connected via RS232 interface to operate and monitor the system.
PLC (Programmable Logic Controller): Acts as the core control unit of the system, responsible for logic control and data processing.
DC Motor: Serves as the actuator, driving the system operation.
- Frequency Converter: Regulates the motor speed to achieve speed control.
- Mine Hoist: The controlled object, driven by the motor to perform hoisting operations.
- DC Power Supply: Provides DC electrical energy to the system.
- High Voltage Cabinet: Handles high voltage power to ensure safe system operation.
- Metering Cabinet: Used for electrical energy measurement and monitoring.
- Main Control PLC: Responsible for overall system control and coordination.
2. Working Process
1. Operation and Monitoring: The system is operated and monitored through the operator console and host computer, with commands transmitted to the PLC via the RS232 interface.
2. Control Logic: The PLC performs logic judgment and data processing based on received commands, generating control signals.
3. Motor Drive: Control signals are sent to the DC motor, which starts and drives the mine hoist operation.
4. Speed Regulation: The frequency converter adjusts the motor speed as needed to achieve precise speed control.
5. Power Supply and Management: The DC power supply provides energy to the system, the high voltage cabinet handles high voltage power, and the metering cabinet measures and monitors electrical energy to ensure stable system operation.
