Constant Power Speed Control System for Portal Crane Based on Weight Sensor Signal Acquisition
In order to improve the working efficiency of the portal crane and reduce the working energy consumption,a constant power speed regulation system for poratl crane based on weight sensor signal acquisition is optimized and designed.The analog signal of the weight sensor is sent to the PLC for calculation and processing,the weight signal is converted into a corresponding speed signal and then sent to the frequency converter,so as to achieve constant power speed regulation for different loads and speeds.
