Specific embodiment
In order to make the application the technical staff in the technical field be more clearly understood that the application, with reference to the accompanying drawing,
Technical scheme is described in detail by specific embodiment.
The present invention provides a kind of Dynamic Trackings of rotary type annealing furnace furnace trolley position.
Currently, most of similar producing lines mostly use coding cable directly to measure the position of coil of strip or survey by photoelectric encoder
Dimension rolls up mobile angle to obtain location information, and test desk truck position precision is low.And then present invention employs physical location inspections
It surveys and theoretical position calculates the method that combines to track the position of trolley, broken the cognition of traditional position of steel coil tracking.
The present invention is suitable for the position positioning scenarios of more trolleys.
Implementation principle of the invention please refers to Fig. 1.
In Fig. 1, rotary type annealing furnace furnace be in circular ring type, be divided into multiple furnace areas (such as 8 areas Ge Lu), the quantity of trolley and
The quantity in furnace area is consistent, and the number in furnace area is in a direction incremental, such as counter clockwise direction；Secondly the number of trolley is and furnace
Area is opposite, and furnace area is counterclockwise to be incremented by, trolley is exactly to be incremented by clockwise, and each furnace area (can also be with comprising one
Referred to as one group) trolley.
The construction of each trolley all is the same size, but each trolley has respective number.8 trolleys are sequentially connected
(such as trolley shown in Fig. 1), and sequentially pass through each furnace area.
Coil of strip is all placed on each trolley.
And it is fitted with buting iron at the vehicle bottom of each trolley, contact is fixedly installed in some furnace area or several furnace areas
Switch.
During trolley passes through furnace area, pass through the buting iron of trolley and its contact-making switch triggering coding letter for passing through furnace area
Number, the number of the trolley is obtained by analyzing the encoded signal, and further with calculate obtain the trolley theory number into
Row comparison.The position of the trolley is obtained if number is consistent.
Since all trolley structures are all the same and are sequentially connected, and then can be according to the position of the trolley and other
The sequentially connected relationship of vehicle extrapolates the position of other trolleys.
Continuing with reference to Fig. 1,8 trolleys are sequentially connected (such as trolley shown in Fig. 1), and sequentially pass through each furnace area.
If the trolley is the 1st trolley, position is in the 1st furnace area, then according to the trolley and the trolley of front and back one
Connection relationship adds 1 in the number of the trolley, obtains the trolley number in the area Shang Yilu, subtracts 1 in the number of the trolley, obtain
The trolley in next furnace area is numbered.For example, the trolley is in the 1st furnace area, the trolley that the 8th furnace area is obtained after adding 1 is the 2nd platform
Vehicle, the trolley that the 2nd furnace area is obtained after subtracting 1 is the 8th trolley, since each trolley successively has connection relationship, and then can be calculated
Obtain the trolley number in other furnace areas.
Certainly, after the number for obtaining each trolley, judge whether the number is 0, if so, by next furnace area
Trolley number is defined as maximum number.
In the specific implementation process, Fig. 2 is please referred to below, is a kind of rotary type annealing furnace furnace trolley position of the invention
The implementation process figure of Dynamic Tracking.
S1, when front chassis rotates, by being installed on the buting iron of the current pallet bottom and being installed on a furnace area
Close to the mutual triggering of switch, the encoded signal for working as front chassis is obtained.
It is the gear by the pallet bottom for working as front chassis close to switch cooperation of fixed installation when the encoded signal of front chassis
This encoded signal is combined by iron to obtain according to binary coding.For example, being triggered close to switch by buting iron, believed
Number think " 1 " in binary system；It is not triggered close to switch by buting iron, its signal is thought to " 0 " in binary system.One group close
Switch forms one group of binary coding by practical triggering situation.
It referring to Fig. 3, is buting iron and the specific location schematic diagram close to switch.
In the specific implementation process, the fixation position in a certain furnace area of furnace bottom is mounted on close to switch, it is fixed；It is close
The quantity of switch is determined by trolley quantity, and the binary coding maximum value of the quantity composition close to switch is greater than institute
State trolley quantity.Such as the quantity of trolley is 50, and the value of binary number " 11111 " is 31, binary number " 111111 "
Value is 63, therefore minimum needs 6 detect the trolley position of 50 groups of trolleys close to switch (number 1,2,3,4,5,6).
Being assembled in the bottom of each trolley can trigger with the buting iron 7 for generating encoded signal close to switch triggering
Exactly the trolley of this group of trolley is numbered after the binary coding formed close to after switch is converted, in trolley rotary course,
Buting iron 7 is also moved together with trolley.Therefore, the quantity of the buting iron 7 of different trolleys and position are all different, and then different platforms
When vehicle is gone to close to the position of the switch, because of trolley difference, the encoded signals also different close to switch, and then obtaining of trolley triggering
It is different.
The quantity of the buting iron of each trolley is arranged according to the number of the trolley and close to the quantity of switch.And buting iron
Position with close to switch position it is related.Quantity close to switch determines binary-coded digit, and the number of trolley
Determine binary-coded code clerk.Such as No. 1 trolley, and the quantity of close switch is 6, then its number that buting iron is arranged
Amount is 1, and the position of buting iron can obtain encoded signal 000001 with close to switch triggering, obtain by the calculation process of PLC
To denary number 1, then the 1 actually detected trolley number of trolley, i.e. A=1 thus.Such as No. 9 trolleys again, go to close to the position of the switch
When, triggering close to switch be the 1st and the 4th, then this 6 close to switch form binary codings be
" 001001 " obtains denary number 9 by the calculation process of PLC, then the 9 actually detected trolleys number of trolley, i.e. A=9 thus.
As a kind of optional embodiment, when the position of front chassis is by the buting iron triggering with the current pallet bottom
Determine close to switch.Due to being fixed and invariable close to the position of switch, and then can be according to true close to the position of switch
It makes when the position of front chassis.It is then based on the connection relationship and size relationship when front chassis and other trolleys, determines residue
Trolley position.And before this, whether the number that the present invention needs detection to work as front chassis corresponds to, and can further obtain
When the position of front chassis.
S2 analyzes the encoded signal by PLC and obtains the number for working as front chassis.
This coding obtains decimal number by the operation of PLC, and as (reality) number A of front chassis, while PLC will work as
The actual number of front chassis sends the DCS system of server to.
S3 receives the number described in the PLC transmission when front chassis by server.
S4 is obtained based on the actual number of a upper trolley when the theoretical of front chassis is numbered by the server.
Theory is calculated based on numbering the actual number that calculating is a trolley of DCS system or more when front chassis correlation
Number.DCS system adds 1 on the basis of the actual number of upper primary trolley, obtains the theoretical number of this trolley, as currently
The theoretical number B of trolley.
As a kind of optional embodiment, after this, whether the present invention judges the theoretical number for working as front chassis
For trolley maximum number；If so, being lowest number by the theory value of next trolley.For example, working as the theory of front chassis
When number reaches maximum trolley, next time can restart when calculating from 1.
S5 passes through server comparison the numbering with described when the theoretical of front chassis is numbered when front chassis.
S6, if the number when front chassis and described when the theoretical number of front chassis is consistent, be based on it is described currently
The buting iron triggering of pallet bottom close to switch, determine the position for working as front chassis.
After physical location and theoretical position all calculate, the two is compared, if A=B, illustrate trolley position with
Track is normal, then based on the buting iron triggering with the current pallet bottom close to switch, determination is described when the position of front chassis；Such as
Fruit A ≠ B then illustrates trolley position tracking mistake.
In addition, when determining when the position of front chassis, it can be based on the connection relationship when front chassis and other trolleys
And size relationship, determine the position of other trolleys.It is, of course, also possible to derive the number of other trolleys.
As a kind of optional embodiment, the present invention is not restricted to carry out trolley position close to switch in an area Ge Lu
Detection can install multiple groups close to switch in different furnace areas, then further determine that pair by comparing the number of multiple trolleys
The position of trolley is answered, control system can be made relatively reliable in this way.
For example, the present invention is also equipped in the second furnace area close to switch.When the second trolley is (except other in addition to the front chassis
Trolley) when passing through the second furnace area, by the buting iron being thoroughly arranged of second trolley and it is fixed at connecing for the second furnace area
The mutual triggering closely switched obtains the encoded signal of second trolley；
The number by second trolley is obtained by the encoded signal that PLC analyzes second trolley；
The number for second trolley that the PLC is sent is received by server；
The theoretical number of the second trolley is obtained based on the actual number of a upper trolley by the server；
The number of second trolley and the theoretical number of second trolley are compared by the server；
If the number of second trolley is consistent with the theoretical number of second trolley, it is based on and described close to switch
In the position in second furnace area, the position of second trolley is determined.
The second furnace area herein can be one or several in other furnace areas in addition to above-mentioned furnace area, and quantity is not done
Limitation, and implementation principle is the same.
The advantage of doing so is that by the way that contact-making switch is arranged in multiple furnace areas, to detect through the trolley in each furnace area
It numbers, and then determines the position of each trolley, if the trolley number of each furnace area detection and position, be somebody's turn to do with what other furnace areas derived
The number and position consistency of trolley, then can then be further ensured that precision and reliability that the present invention is implemented.
This method have the advantage that used device is simple, calculating process and principle are readily understood, calculate accurate, of the invention implementation
Structure is simple, easy to maintain, meanwhile, detection accuracy and reliability are substantially increased because of the maintenance-free feature of close switch.
