Description
Technical field
The utility model relates to Motor Control, particularly a kind of multi-motor control system.
Background technology
At present, the application of multi-motor coordination motion control in industrial circle is more and more extensive, control precision and technological requirement also more and more higher.Only operate by certain proportionate relationship synchronous coordination between guaranteed multiple motor, just can guarantee the normal operation of system.Early stage Multi-motor control method is decentralized control, and system adopts multiple central processing unit to complete the control task of controlled device, that is, by adopting converter technique (PWM), implements man-to-man control with a frequency converter to a motor.This control mode, needs for each group of motors is equipped with a set of control system, and not only investment large management controllers is many, and control system also power consumption.Therefore, need badly multi_motor control mode is improved.
Utility model content
For the defect of prior art, the utility model provides a kind of multi-motor control system.
A kind of multi-motor control system, comprises the power subsystem, pwm pulse generation unit and the switching tube unit that connect successively; The input of described power subsystem is connected with the high frequency filter be made up of electric capacity C1 and inductance L 1 through fuse F1, and the output of high frequency filter connects bridge rectifier BD1, and the output of bridge rectifier BD1 connects filter capacitor C2; Described pwm pulse generation unit comprises switch subelement, TM320C5509 chip and supply voltage detection sub-unit, and after filter capacitor C2 filtering, TM320C5509 chip is exported on a road, and supply voltage detection sub-unit is exported on another road; Switching tube unit comprises multiple switching tube, and wherein each switching tube is connected with every road direct current machine and each direct current machine parameter is identical respectively.
The beneficial effects of the utility model are: the utility model by a set of control system, can adopt a central processing unit to control multiple motor and run, greatly reduce system cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model multi-motor control system.
Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail embodiment of the present utility model below in conjunction with accompanying drawing, make above-mentioned and other object of the present utility model, Characteristics and advantages will be more clear.Reference numeral identical in whole accompanying drawing indicates identical part.Deliberately do not draw accompanying drawing in proportion, focus on purport of the present utility model is shown.
As shown in Figure 1, system comprises the power subsystem, pwm pulse generation unit and the switching tube unit that connect successively.The input of power subsystem is connected with the high frequency filter be made up of electric capacity C1 and inductance L 1 through fuse F1, and the output of high frequency filter connects bridge rectifier BD1, and the output of bridge rectifier BD1 connects filter capacitor C2.System adopts AC-powered, input ac voltage is after fuse F1, through electric capacity C1, inductance L 1 High frequency filter, after bridge rectifier BD1, electric capacity C2 rectifying and wave-filtering, TM320C5509 chip is exported on a road, and supply voltage detection sub-unit is exported on another road.
Pwm pulse generation unit comprises switch subelement, TM320C5509 chip and supply voltage detection sub-unit, TM320C5509 chip is for generation of pwm pulse signal, switch subelement starts for control TM320C5509 chip or stops producing pwm pulse signal, supply voltage detection sub-unit is used for detecting supply voltage in real time, and testing result is sent to TM320C5509 chip, when TM320C5509 chip judges supply voltage lower than preset value, stop producing pwm pulse signal.Switching tube unit is used for described pwm pulse signal being converted to the drive singal driving multi-channel DC motor, switching tube unit comprises multiple switching tube, wherein each switching tube is connected with every road direct current machine and parameter is identical respectively, and described parameter comprises ON time, conducting resistance, turn-off time etc.In the circuit, pwm pulse generation unit produces pulse signal, this pulse signal controls the switching of multiple switching tube simultaneously, because the parameter of multiple switching tube is identical, identical according to conservation of energy principle and switching tube physics, electrical characteristic, the energy that every road direct current machine obtains is equal, so identical by the electric current of every road direct current machine, thus realize every road direct current machine uniform current coupling, realize multi-motor control.
Set forth a lot of detail in the above description so that fully understand the utility model.But above description is only preferred embodiment of the present utility model, the utility model can be much different from alternate manner described here to implement, and therefore the utility model is not by the disclosed concrete restriction implemented above.Any those skilled in the art are not departing under technical solutions of the utility model ambit simultaneously, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solutions of the utility model, or be revised as the Equivalent embodiments of equivalent variations.Every content not departing from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solutions of the utility model protection.
