Multi-motor optimization control system and optimization control method thereof

Abstract

The invention provides a multi-motor optimization control system and an optimization control method thereof. The multi-motor optimization control system comprises multiple motors, wherein each motor is connected with a sensor I / O module and a driver; all drivers and sensor I / O modules are connected onto an upper computer; and a one-key tour round button is arranged on the upper computer. The control method comprises the steps of when using for the first time, determining the use quantity; preferably selecting and starting motors; automatically optimization controlling the use quantity of the motors: after a motor runs for a long time, clicking the one-key tour round button, automatically starting one standby motor through the system, stopping the motor running for the earliest time after the standby motor starts normally, and ensuring each motor is located at the optimal working state; and if the motor in use is disorderly shutdown, automatically starting the standby motor through thesystem. According to the multi-motor optimization control system and the optimization control method thereof provided by the invention, by adopting an intelligentized design and aperiodic manual tourround, each motor is located at the optimal state, the use quantity of the motors is intelligently ensured, and the multi-motor optimization control system and the optimization control method thereofare particularly suitable for applicably and conveniently controlling a large-scale modernized public workshop.

Description

technical field [0001] The invention relates to the technical field of motor optimization control, in particular to a multi-motor optimization control system and an optimization control method thereof. Background technique [0002] Compressed air, nitrogen, and oxygen are widely used in various industrial plants. Compressed air is compressed by an air compressor, and then passes through a drying and filtering device to absorb particles and moisture in the air to produce the final purified compressed air; nitrogen and oxygen are generally compressed by an air compressor, and after dehydration , Purification equipment, remove particles, moisture, carbon dioxide, acetylene and alkanes in the air, and then enter the fractionation tower, use the different boiling points of nitrogen and oxygen, separate nitrogen and oxygen through heat exchange, and obtain qualified nitrogen and oxygen. [0003] As the main equipment for preparing these gases, the air compressor mainly uses circu...

Problems solved by technology

If the flow rate of the circulating water pump is small, it will directly cause the temperature of the inlet water to rise and the inlet pressure to decrease, which will cause the air compressor to stop and cause production accidents; if the flow rate of the circulating water pump is large, the energy consumption of the pump will increase, which will affect economic benefits

[0004] The traditional water pump design only uses PLC for remote monitoring, and does not carry out accurate statistics on the running status of the motor equipment itself, such as the total running time, so it is impossible to optimize the selection of the motor equipment

[0005] For example, the intelligent control of motors in public workshops is generally based on the inlet pressure of all equipment, but the collection of pressure itself is closely related to the accuracy and installation of on-site equipment, such as the accuracy of on-site sensors, the technical level and sense of responsibility of construction personnel, etc. , often the fluctuation range of the signal is relatively large, and the real-time program uses PID intelligent control, which usually causes the motor to start and stop repeatedly, which has a negative impact on production and the equipment itself

[0006] In addition, in the past, the motors in public workshops were used for a long time without failure. The disadvantages of this usage method are obvious: motors that have been in operation for a long time affect their life, and motors that have not been used for a long time will directly result in scrapping
