Description
Technical field
The present invention relates to the X line machine in a kind of Medical Equipment, specifically a kind of X line lathe body movement controlling method and control device thereof.
Background technology
In recent years, AC servo has obtained general application as a kind of emerging motion control device and method in every field.In order to improve performance, reduce cost, in the design of X line lathe body, also begin to adopt AC servo to carry out corresponding motor control.But; because armarium has higher requirement to safety; promptly the motor on the bed body should be in complete uncharged state when not moving; so both reduced the risk that the user gets an electric shock; improved the ability of the anti-electromagnetic interference of system again; particularly when causing danger, need protect personal safety and device security in time.Therefore, on X line machine, use AC servo, just should satisfy this safe designing requirement.This with the common method of AC servo on the system structure and all have significantly different on the using method, so need be in conjunction with the safe designing requirement of X line machine, the structure of AC servo and using method redesign a kind of new X line lathe body motion control device and method.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of X line lathe body movement controlling method and control device thereof with high security.
For achieving the above object, the technical solution used in the present invention is:
The inventive method has following steps:
Whether decision operation person presses the motion button; If the motion button is pressed, then control assembly is carried out motor message, the motor rotation; Whether decision operation person the released movement button; If the motion button is released, then control assembly is cancelled motor message, and motor stops.
Wherein said control assembly is carried out motor message and be may further comprise the steps: responsive movement enable signal at first; Control rotates freely signal then; Respond the traffic direction signal at last.Described control assembly cancellation motor message may further comprise the steps: at first cancel direction of motion signal; Control rotates freely signal then; Cancel the motion enable signal at last.
The inventive method also has following steps: whether decision operation person presses the anxious button that stops; Stop button if press suddenly, then cut off the power supply of servomotor, the servo amplifier of control assembly control simultaneously is in servo closing state.
Apparatus of the present invention have servo amplifier and bed body motion servo motor, the control signal output ends of control assembly links to each other with the control signal input of servo amplifier, the outfan of servo amplifier links to each other with bed body motion servo motor by relay, the control coil of this relay links to each other with the motion Enable Pin of Programmable Logic Controller, and the axle anglec of rotation feedback signal of bed body motion servo motor is delivered to the signal input part of servo amplifier by encoder.The control signal of the control end of described control assembly output is servo enabling signal, rotate freely signal and direction of motion signal.Input at control assembly is provided with scram button.Described control assembly is Programmable Logic Controller or is the control core system with single-chip microcomputer or PLD.
The present invention has following beneficial effect and advantage:
1. safe.The present invention by to servo enabling signal, rotate freely the sequencing contro of signal and direction of motion signal, make servomotor when not moving, be in complete uncharged state, reduce human electric shock's risk, improved the ability of the anti-electromagnetic interference of system, satisfied the designing requirement of secure context;
2. reaction fast.When the operator uses emergency stop switch, directly cut off the power supply between servo amplifier and the motor, promptly make motor lose electric energy, can protect personal safety and device security timely and effectively.
Description of drawings
Fig. 1 is a control device structure principle chart of the present invention;
Fig. 2 is the control method flow chart of one embodiment of the invention;
Fig. 3 controls sequential chart for the present invention.
The specific embodiment
As shown in Figure 1, control device of the present invention comprises servo amplifier SD and bed body motion servo motor SM, present embodiment adopts Programmable Logic Controller PLC as control assembly, its control end links to each other with the control signal input of servo amplifier SD, the outfan of servo amplifier SD links to each other with bed body motion servo motor SM by relay J, the control coil of this relay J links to each other with the motion Enable Pin of Programmable Logic Controller PLC, and the axle anglec of rotation feedback signal of bed body motion servo motor SM is delivered to the signal input part of servo amplifier SD by encoder E.Input at Programmable Logic Controller PLC is provided with the anxious button JT that stops.
The control signal of the control end of described Programmable Logic Controller PLC output is servo enabling signal, rotate freely signal and direction of motion signal.
Below with reference to control flow chart shown in Fig. 2,3 and control sequential chart control procedure of the present invention is described.X line lathe body is not when moving, servomotor SM is in complete uncharged state, when the operator presses the motion button, PLC triggers the motion enable signal, and triggering rotates freely and direction of motion signal simultaneously, i.e. closing relay J at first, make servomotor be in readiness, behind the time-delay Δ T1, response rotates freely signal, servomotor SM is in rotatable state, delay time behind the Δ T2, responsive movement direction signal, servomotor SM begin to drive the motion of bed body again, this signal continuously effective, the then perseveration of bed body; When operator's released movement button, Programmable Logic Controller PLC at first cancels direction of motion signal, make a body stop motion, control rotates freely signal behind the time-delay Δ T3, the cancellation motion enable signal behind the Δ T4 of delaying time again, cut off the output of servo amplifier fully, so just can safety disconnection servo amplifier SD and the relay J between the servomotor SM, make servo electric SM machine return to complete uncharged state, reduce human electric shock's risk effectively and improved the ability of the anti-electromagnetic interference of system, satisfied the designing requirement of secure context.
In addition, in the motion of bed body, if dangerous situation, the operator can press the anxious button that stops, and Programmable Logic Controller PLC can at first control and rotate freely signal and make motor be in free rotation state immediately, the bed body also stops action immediately, even this moment, direction of motion signal was triggered always, the bed body can not move yet, behind the recovery emergency stop switch, the bed body also can keep motionless always, presses the motion button once more up to the user.
The present invention can also single-chip microcomputer or PLD be the control core device is realized apparatus of the present invention as control assembly function.
