The density motor (2) is controlled by the density motor controller (4) and used for detecting the moving step number of the stepping motor (1); the stepping motor controller (3) is used for driving the stepping motor (1); both the stepping motor controller (3) and the density motor controller (4) are connected with the microprocessor (5) through I/O (input/output) ports; and the encoder (6) is used for detecting the moving state of the density motor (2) and connected with the microprocessor (5) through an I/O port. The closed-loop control system realizes closed-loop control for the density motor, so that running reliability of the system can be further improved.
Description
Technical field
The utility model relates to electronic circuit field, relates in particular to a kind of controller of straight-bar machines, specifically is a kind of straight-bar machines density electrical machine closed-loop control system of using in the controller of straight-bar machines.
Background technology
Density electrical machine (in the industry sometimes also degree of title order motor) is the vitals of straight-bar machines control count, in the cross machine knitting control system, the closed-loop control system of density electrical machine is used for finishing the accurate measurement of stepper motor being moved step number, thereby step-out, out-of-control phenomenon feedback input signal are handled, the error correcting capability of enhancing system, high reliability.
The motion control of the density electrical machine in the straight-bar machines system is the control system of an open loop at present, if abnormal failure appears in density electrical machine, as situations such as machinery are stuck, thereby just can not realize then that in time the measurement of stepper motor being moved step number makes and can not carry out signal feedback to the operating condition of stepper motor.
The utility model content
The technical problems to be solved in the utility model is, thus provide a kind of can detect the motion state of density electrical machine make the straight-bar machines density electrical machine closed-loop control system that system's operational reliability improves.
Technical solution of the present utility model provides following a kind of straight-bar machines density electrical machine closed-loop control system, comprise stepper motor, controllor for step-by-step motor, density electrical machine, density electrical machine controller and microprocessor, density electrical machine is by the control of density electrical machine controller and be used to detect the detection that stepper motor moves step number, controllor for step-by-step motor is used for driving stepper motor, described controllor for step-by-step motor all is connected by the I/O mouth with microprocessor with the density electrical machine controller, also comprise the encoder of the motion state that is used for detecting density electrical machine, described encoder is connected by the I/O mouth with microprocessor.
After adopting above scheme; the utility model has been set up encoder to density electrical machine the running status of density electrical machine has been detected; if density electrical machine breaks down; then can feed back the signal of density electrical machine operation troubles and give microprocessor; feeding back to the density electrical machine controller after microprocessor is handled fault again realizes troubleshootings such as density electrical machine shutdown; realize the closed-loop control of density electrical machine, thereby made reliability of system operation be further enhanced.
