Technical field
The present invention relates to a kind of step-by-step control system, relate in particular to the control device of this step-by-step control system.
Background technology
Stepper motor can be defined as simply: according to the pulse signal of input, excited state of every change certain angle that just advances then keeps certain position and static motor as not changing excited state.The mechanism of stepper motor is based on the most basic electromagnet effect.Stepper motor, step actuator, controller constitute the indivisible three parts of robotization (stepping) control system, are one of exemplary practical schemes of electromechanical integration.Its system chart is as shown in Figure 1, and wherein: control module is upper control, and step actuator is a motion control unit, and stepper motor is a movement executing mechanism, and mechanical motion mechanism is a movement executing mechanism.
Develop rapidly along with electronic control system over past ten years; Robotization (stepping) control system has infiltrated into numerically controlled every field, particularly widespread use in many different fields such as OA machine (Office Automation), FA machine (Factory Automation) and computer peripheral.But in same machine (equipment), need different directions and equidirectional and when showing the mechanical motion of N item, need have N group step-by-step control system to control its mechanical motion jointly, to reach the purpose of its automatically working.Its system chart is as shown in Figure 2.This shows that N independent control arranged in this scheme altogether, the complex work that collaborative its interoperation is accomplished complete machine is extremely difficult, and the existence of N controller causes its cost too high.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of intelligent automation stepping control device of CAN fieldbus structure LAN formula, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme:

Adopt the CAN fieldbus and the CAN communication interface of prior art among the present invention:
The CAN fieldbus has non-destructive bus arbitration technology, keeps CAN fieldbus transmission state normal; Node on the network can reach 110; The field bus communication form adopts short frame format, and every frame information all has CRC check and other error detection measures, guarantees reliability of data communication; Node have the ability identification permanent fault and temporary transient disturbance, closing fault node automatically, anti-interference is good.The CAN fieldbus is from automobile industry development and the bus communication technology that comes, be at present in all bus communication technologies interference free performance best one of, thereby be fit to very much the special needs of plant processes control.
The CAN communication interface is the special IC of the translation function of communication driver and receiver electrical characteristics mode, is the bridge between CAN bus and microprocessor (CPU) unit.The communication speed of transfer rate and CAN bus is complementary.CAN communication interface special IC is implanted in hand-held controller or the intelligent stepper motor driver, more to be met very easily in interconnected requirement.
Intelligent automation (stepping) control system:
Form by the intelligent step actuator and the stepper motor of band scrambler; Because the CMOS microprocessor (CPU) that intelligent step actuator inside has eight low-power consumption is as information processing centre; Stack sensing and inner sampling function have had the basis of realizing motor function control, compensation calculating, parameter modification, warning, demonstration, monitoring, optimization and the incorporate comprehensive automation function of keyholed back plate.
Adopt the online manipulater of prior art:
Being one can grip by one hand, the manipulater of one-handed performance; Has the sixteen bit button as inputting interface; The interface of the big LCDs of one 2 inch as idsplay order and each node motion state arranged; Core is the CMOS microprocessor (CPU) of eight low-power consumption.It can be through the man-machine dialog interface of keypress function and LCDs composition; Through built-in CAN communication interface; Directly be sent to the work order that requires without control module on the embedded micro-processor of intelligent stepping motor system of assigned address, command the intelligent stepping motor system of this position to move and the parameter of inquiring about motion change shows on LCDs in real time.It is less demanding to user of service's technical ability, and very suitable FA machine slip-stick artist debugs nearby when carrying out plant maintenance or the operative employee adjusts production status work nearby.
The present invention directly connects with the main control unit of FA machine through a CAN communication interface, realizes tens groups to the motion control of the highest 110 groups of intelligent automations (stepping) control system and the management and control work of query State; Owing to adopt the CAN fieldbus as communication unit; Flexible and the extremely strong antijamming capability of communication that the CAN fieldbus is had; Ensure the stability and the high reliability of total system work, satisfied compoundization of function and the new demand of monitoring in real time of FA machine.
