Summary of the invention
For solving above-mentioned problems of the prior art, according to the size of current of electrical motor, can reflect intuitively this rule of payload of belt conveyer, the invention provides a kind of increase and decrease that can judge according to the motor current size automatically detecting driving motor quantity, and many motor driven belts formula conveyer that auto-controlled motor stops or starting subtracts intelligent motor control setup.
The invention provides a kind of many motor driven belts formula conveyer and subtract electrical machine energy-saving operation intelligent controlling device, comprise power supply, central process unit (CPU), digital quantity input/output module, analog input module, current transducer, change-over switch S1 and relay, wherein: change-over switch S1 connects digital quantity input module by relay; Central process unit (CPU) is connected by internal bus with digital quantity input/output module, analog input module; Current transducer is connected with analog input module; Power supply is whole system power supply;
Further, change-over switch S1 and relay are connected to load module by motor start-up, the danger signal of central control system output, startup, danger signal that central process unit (CPU) collects by coupled load module, and the motor current signal gathering according to the current transducer being connected with analog module, determine input and the excision of electrical motor, and the startup of electrical motor, danger signal are outputed on the contactless switch of electrical motor by output module, thereby control motor start-up and stop.
The motor that intelligent controlling device of the present invention is installed on belt conveyor system drives cashier's office in a shop, subtracts current transducer in intelligent motor control setup and is connected on conveyer drive motor current transformer; By current transducer, be input to analog module, central process unit (CPU) detects after analog input, by inner analog input module, detect the size of outside belt conveyor system motor current, and the current value detecting and setting value are contrasted, relatively input value and the difference of setting current value, by comparing result, judge the increase and decrease of driving motor quantity, determine the switching of motor, and then automatically send the order of controlling electric motor starting or disconnection, and output switching signal is to digital output module.Output module outputs to the contactless switch of motor driving cabinet, realizes input and the excision of motor.
Owing to adopting technique scheme, the present invention has the following advantages and effect:
Belt conveyer of the present invention subtracts intelligent motor control setup, and control system advanced person can realize length was controlled automatically apart from overall process, all the period of time of multiple-motor points driving for belt conveyor motor driven systems.
Accompanying drawing explanation
Fig. 1 is many motor driven belts of the present invention formula conveyor drive system diagram;
Fig. 2 is the circuit structure schematic diagram that belt conveyer of the present invention subtracts intelligent motor control setup.
The specific embodiment
With reference to figure 1, belt conveyer is driven with actuating device by 2 covers or 2 covers, is respectively the compositions such as electrical motor 11, fluid coupling 12, retarder 13, overriding clutch 4, driving drum 5, coupler 6, retarder 27, fluid coupling 28, electrical motor 29.Between electrical motor 11 and belt conveyor, by fluid coupling 12, retarder 13, overriding clutch 4, be connected with the driving of driving drum 5; Between electrical motor 29 and belt conveyor, by fluid coupling 28, retarder 27, coupler 6, be connected with the driving of driving drum 5.
With reference to figure 2, intelligent controlling device of the present invention comprises power supply, central process unit (CPU), digital quantity input/output module, analog input module, current transducer, change-over switch S1 and relay etc., wherein, change-over switch S1 connects digital quantity input module by relay; Central process unit (CPU) is connected by internal bus with digital quantity input/output module, analog input module; Current transducer is connected with analog input module; Power supply is whole system power supply, and the motor that this intelligent controlling device is installed on belt conveyor system drives cashier's office in a shop.
The current transformer of the electrical motor 29 of described belt conveyor system connects above-mentioned current transducer; Central control system outputs to startup, the shutdown signal that belt conveyer electrical motor 11 drives cabinet, is connected to belt conveyer and subtracts in the interior S1 change-over switch of intelligent motor control setup; Belt conveyer subtracts startup, the shutdown signal of intelligent motor control setup output, is connected to startup, shutdown signal that belt conveyor system electrical motor 11 drives cabinet; Belt conveyer subtracts motor control assembly built-in motor run signal and is parallel to belt conveyor system electrical motor 11 and drives electrical motor 11 run signal of cabinet.The current measurement value of electrical motor 29 is input to analog module by current transducer, central process unit (CPU) detects after analog input, relatively input value and the difference of setting current value, the switching of decision electrical motor 11, and output switching signal is to digital output module.Output module outputs to electrical motor 11 and drives the contactless switch of cabinet, realizes input and the excision of electrical motor 11.When after the input of electrical motor 11, by fluid coupling 12, retarder 13, overriding clutch 4 by transmission of power to driving drum 5; When after the excision of electrical motor 11, overriding clutch 4 separates simultaneously, and fluid coupling 12, retarder 13 shut down immediately.Thereby reach the object of controlling double motor operation or monomotor energy-saving run.
