Abstract


Pendulum sand Saw the stone industry processing equipment , each set of equipment in a work cycle , the load of the main drive motor in the severity of load variation , nearly half of the time in the light load or no-load state , operating efficiency low energy wasted is very serious . Therefore, the operating characteristics of the stone processing equipment pendulum sand saw , study its main drive AC motor energy-saving technology , has a very important economic and social benefits . Thesis Stone Co., Ltd. Xiamen high ALCIONE-600-2B tilting sand saw energy saving object tilting sand saw detailed structure and work process , pointed out that the key to the energy efficiency of their system is that sand Saw regulator energy saving soft start process . And for the design and development of its energy-saving controller , specific work as follows : First, the paper combined with sand Saw basis compared to the commonly used motor soft starter , heavy-duty starting characteristics , discrete frequency soft starting method , when the motor starter discretized by frequency voltage into low-frequency voltage , so as to achieve the purpose of the starting torque , suppress the inrush current . The simulation results show that the discrete variable frequency soft start technology transformation sand Saw soft start is not only a substantial increase in starting torque , can effectively inhibit the starting inrush current . Followed by analysis and comparison of the main motor regulator energy saving strategies , and combined with the Tilting sand saw processing characteristics and load characteristics , energy-efficient design of a motor fuzzy controller , the controller as an input to the load factor and power factor amount trigger angle change in the output to achieve motor Voltage Energy Saving the Matlab simulation results verify the feasibility and effectiveness of the program through the development of the fuzzy rules . Finally, TMS320LF2407A DSP chip produced by TI as the core, tilting sand saw motor energy-saving controller hardware and software design . The hardware design of the system , including peripheral control circuit thyristor main regulator circuit , and DSP as the core design . The software design is mainly divided into the trigger pulse module , power factor detection module , load rate calculation module and the module of the design of energy-saving control algorithm .
