Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Fig. 2 is the flow chart of roll location measurement method of the present invention.As shown in Fig. 2, shown roll location measurement method, packet
It includes:
Step 11: obtaining zero signal, the zero signal is the inductive signal close to switch.
Step 11 specifically includes:
Step A1: will be mounted on dead-center position close to switch, and the dead-center position is the minimum position of roll；
Step A2: control stepper motor reversion drives roll mobile towards the close direction close to switch；
Step A3: when obtaining the inductive signal of the close switch, the step motor stop is controlled.
Step 12: zero is set by the data of current magnetic head, specifically: data in high-speed counting pulse converter are clear
Zero, the high-speed counting pulse converter is arranged in the controller, the high-speed counting pulse converter and the magnetic head
Connection.
Step 13: control stepper motor rotates forward, and the stepper motor drives roll mobile；
Step 14: obtaining the position data of the roll of magnetic head acquisition；The magnetic head is disposed proximate to described close to switch
Position.
Step 15: judging whether the roll reaches setting position, obtain the first judging result.Such as on this production line
The square steel of 400 × 400 and 300 × 300 two kinds of models can be produced.When producing the square steel of 400 × 400 models, 12 on production line
The roll location of platform unit can be denoted as incremented by successively from 0-100；And when producing the square steel of 300 × 300 models, production line
The roll location of upper 12 units has corresponding adjustment, can be denoted as incremented by successively from 50-150.So for different types of side
Steel, different units have different roll location parameters, and the data that this parameter reference field worker manually adjusts are in program
Middle setting.
Step 16: if first judging result indicates that the roll reaches the setting position, controlling the stepping electricity
Machine stalling；
Step 17: according to the magnetic head acquire position data determine magnetic railings ruler pass through distance, the magnetic scale with it is described
Roll synchronizing moving；The magnetic scale is 1-3mm at a distance from the magnetic head, and the magnetic head senses the magnetic grid on the magnetic scale simultaneously
A/B phase pulse signal, which is converted, by location information is sent to high-speed counting pulse converter.Before rotating forward starts, high-speed counting pulse
Data in converter have been cleared, therefore its data is 0.After rotating forward starts, collected number in high-speed counting pulse converter
According to being exactly real value.This real value divided by 50 be exactly magnetic scale pass by actual range (because magnetic scale it is every by 1mm generate 50
Pulse).
Step 18: the distance passed through according to the magnetic scale and the position close to switch apart from unit determine the roll
Position.
The above method of the invention is realized in controller, wherein controller is using RS485 mechanics of communication and the magnetic head
Connection.
In addition, tele-control system selection of the present invention is siemens PLC SMART series of PLC.Industry is existing
Field bus technology is RS485 mechanics of communication, it can be achieved that telecommunication.Also there are a nets by siemens PLC SMARTPLC itself
Network interface can be extended by Industrial Ethernet Ethernet/IP and be communicated.
The measuring magnetic railings ruler in the position that the present invention uses is divided into magnetic head and magnetic scale two parts, and working principle is magnetic head induction
Magnetic coral on magnetic scale is away from being converted into distance.The advantages that sensor has precision high, is hardly damaged, waterproof and oilproof, can adapt to
The adverse circumstances at scene.
Fig. 2 is that the structure connection figure for the measuring device that roll location measurement method of the present invention uses (is not shown close in Fig. 2
The position of switch).As shown in Fig. 2, the roll location measuring device, comprising: rack 1, bearing 3, sliding block 4, magnetic scale 6, magnetic head 7
With head suspension 5；Bearing 3 is separately connected stepper motor (being not drawn into figure) and roll 2, between stepper motor and roll 2
Transmission adjusts the position of roll 2.Bearing 3 passes through rack 1, and sliding block 4 is fixed on bearing 3, moves with bearing 3, roll 2.
Magnetic scale 6 is fixed on one end of sliding block 4, moves as measuring device with sliding block 4.Head suspension 5 is L shape thin-slab structure, magnetic
The short side of head bracket 5 is fixed in rack 1, and the long side of head suspension 5 is used for fixed head 7, and magnetic scale 6 is being arranged in just in magnetic head 7
Top.The same side of rack 1 is arranged in magnetic scale 6 and magnetic head 7, and magnetic scale 6 is not contacted with magnetic head 7.When magnetic scale 6 is by magnetic head 7, magnetic
First 7 can incude and record the distance of the process of magnetic scale 6.
Method of the invention can be roughly divided into following steps:
Step 1: giving zeroing.When system electrification or remodel starts, system controls motor reversal, makes roll 2, bearing
3 is mobile towards close 1 direction of rack together with sliding block 4.When sliding block 4 is moved to close in front of switch, close to inductive switching
To the sliding block 4 of iron material matter, signal is issued to system.After receiving the signal, control motor stops system, while counting in high speed
Write-in 0 in number pulse converter, sets zero point for the position of magnetic head 7 at this time, and the position of magnetic head 7 is referred to as zero point position at this time
It sets.
Step 2: real time position measurement.It is returned in zero point and high-speed counting pulse converter after write-in 0 in roll location,
System controls motor and rotates forward, and adjusts roll to the target position of setting.In roll moving process, magnetic scale is fixed on sliding block 4
With roll synchronizing moving.Magnetic head 7 can sense and record the distance of magnetic scale process, that is, distance of the roll apart from zero point,
Referred to as real time position.The every mobile 1mm of magnetic scale, magnetic head 7 can generate lower 50 pulses accordingly, therefore the reachable ± 0.02mm of its precision.
Step 3: calculating roll location.For convenience of field worker operation, when needing the reading of magnetic scale 6 plus dead-center position
The distance of magnetic head 7 to rack 1 shows that on the touchscreen the distance referred to as roll location is used as adjustment roll position to field worker
The reference set.Its calculation formula is: roll location=real time position+dead-center position.
The present invention proposes that a kind of roll location measurement method based on magnetic railings ruler, this method pass through close to switch setting zero
Point acquires data measured by magnetic railings ruler by high-speed counting pulse converter, is then passed in PLC and is handled, obtain reality
The roll location on border.Network interface is left in PLC, and data can be remotely provided.
Used herein a specific example illustrates the principle and implementation of the invention, and above embodiments are said
It is bright to be merely used to help understand method and its core concept of the invention；At the same time, for those skilled in the art, foundation
Thought of the invention, there will be changes in the specific implementation manner and application range.In conclusion the content of the present specification is not
It is interpreted as limitation of the present invention.
