Description
Technical field
The present invention relates to equipment operation positioning field, particularly a kind of localization method and positioning system based on spacing equipment operation.
Background technology
The equipment running location system is applied to industry-by-industry, take metallurgy industry as example, has a lot of equipment to come and go both direction when operation, need to judge that it is in service or residing position when stopping by limit switch.For example, the operation of ladle trolley, the opening and closing of dedusting kennel door, the lifting of thermometric, sampling gun etc.
Referring to Fig. 1, it has shown the general synoptic diagram based on spacing running location system.A kind of equipment is done back and forth the back and forth movement of both direction along same path, rely on a plurality of spacing different controls of carrying out in the way: slow down, accelerate or stop etc., also rely on spacing its current position that is positioned of judging simultaneously.Spacing can have a plurality ofly, and its input signal is used respectively " spacing 1 " to existing in Fig. 17 as example, and " spacing 2 ", " spacing 3 " ..., " spacing 7 " represent; The status signal that outputs to display unit of its correspondence is used respectively " website 1 ", and " website 2 ", " website 3 " ..., " website 7 " represents; The input signal of the state of two traffic directions of equipment is used " direction of motion 1 " (from right to left), and " direction of motion 2 " (from left to right) represents.Highway section between spacing and spacing is expressed as respectively: " highway section 1 ", and " highway section 2 ", " highway section 3 " ..., " highway section 6 " represents.
Existing control program generally is divided into two kinds: (1) adopts the control mode of signal self-insurance, and (2) adopt the mode of rest-set flip-flop set control.
The below is spacing with 1, and centre " website 4 " and " highway section 4 " of getting among Fig. 1 are example, set forth its control thought; The control mode of remaining " website " and the demonstration in " highway section " such as its are identical.
Referring to Fig. 2, it has shown the logical diagram of control program 1 in the present technology, adopts the control mode of signal self-insurance:
When equipment runs to the 4th when spacing, " spacing 4 " signal has come, and other all limit signals all do not have next the time, and " leaving website 4 signals " be 0 o'clock, output " website 4 " display.(this part is as logical one)
" website 4 " signal is not only as output display, and the participation logic control.
When equipment broken through the 4th spacing, operate in the 4th spacing and the 5th spacing between the time, " spacing 4 " signal has not had, other limit signal has not had yet, this moment, " website 4 " signal has replaced " spacing 4 " signal in " logical one ", and " website 4 " signal is kept.Herein, namely be the control mode of so-called " signal self-insurance ", namely use " website 4 signals " to keep " website 4 " signal of self.(this part is as logic 2)
Meanwhile, namely when equipment just broken through the 4th spacing, when " website 4 " signal comes, and all limit signals have not all had (i.e. " spacing 4 " just disappeared moment), to export " leaving website 4 " signal be 1.(this part is as logic 3)
Become for 1 moment at " leaving website 4 " signal from 0, the negate signal of " leaving website 4 " that " logical one " and " logic 2 " is inner becomes 0 from 1, then makes the display of " website 4 " become 0, indication equipment left the 4th spacing.(this part is as logic 4)
Same moment like this, " leaving website 4 " signal has replaced " website 4 " signal in " logic 3 ", and signal keeps will " to leave website 4 ".Also adopted the control mode of " signal self-insurance " herein.(this part is as logic 5)
At " leaving website 4 " signal sometimes, if this moment, equipment was " traffic direction 2 " (among Fig. 1 from left to right), then trigger " highway section 4 " display, display unit can awareness apparatus be operate in the 4th spacing and the 5th spacing between.(this part is as logic 6)
The same with top control thinking, can draw " leaving website 5 " signal.At " leaving website 5 " signal sometimes, if this moment, equipment was " traffic direction 1 " (among Fig. 1 from right to left), also trigger " highway section 4 " display, display unit can awareness apparatus be operate in the 4th spacing and the 5th spacing between.(this part is as logic 7)
When equipment continues operation, touch nextly when spacing, then " highway section 4 " display in " logic 6 " or " logic 7 " is become 0.(this part is as logic 8)
Then, according to the control thinking cycle control of front.
Referring to Fig. 3, Fig. 3 has shown the logical diagram of the control program 2 in the present technology, adopts the mode of rest-set flip-flop set control:
When equipment runs to the 4th when spacing, " spacing 4 " signal has come, and then directly outputs to display unit " website 4 " signal.(this part is as logic 9)
When equipment is run into the 4th when spacing, if this moment, equipment was " traffic direction 2 " (among Fig. 1 from left to right); Or, equipment run into the 5th spacing, and when this moment, equipment was " traffic direction 2 " (among Fig. 1 from left to right), by rest-set flip-flop with " highway section 4 " display SET set.After this, " highway section 4 " will remain 1 always, until be 0 by the RESET reseting signal reset of rest-set flip-flop.(this part is as logical one 0)
When equipment continues operation, touch nextly when spacing, can activate the RESET reset signal of rest-set flip-flop, " highway section 4 " signal is reset to 0.Consider next spacing might breaking down, the general employing touches lower two when spacing, just can activate the RESET reset signal of rest-set flip-flop.In the situation of two direction of motion, " highway section 4 " lower two spacing be exactly " spacing 3 ", " spacing 4 ", " spacing 5 " and " spacing 6 " are as long as just be reset to 0 with " highway section 4 " when wherein arbitrary signal comes.(this part is as logical one 1)
The control thinking in remaining " website " and " highway section " as before.
As seen from the above, the method based on spacing operation location in the existing technology generally all is the mode that adopts the mode of signal self-insurance or adopt rest-set flip-flop control, simultaneously, and other the limit signal of in control loop, having connected.Practical application is got off, and there is following drawback in existing control system under unusual condition, do not have error correction and robustness:
(1) in other limit switch generation signal fault or signal wrong report, all influential when aobvious to current spacing and location status.
(2) adopt the mode of signal self-insurance or the mode that adopts rest-set flip-flop set to control, do not consider in the thorough situation at various unusual conditions, can not in time cancel the self-insurance of signal or the signal of aaset bit resets, thereby often cause the demonstration of error signal.
(3) adopt the mode of signal self-insurance or the mode that adopts rest-set flip-flop set to control, just need the programmer to various unusual conditions consider very thorough, thereby the designer to program has proposed very high requirement, is unfavorable for design and the deciphering of program.
(4) sometimes the display of " website " or " highway section " not only is used for the output of display unit, and the simultaneously also operation of participation device control.In case when other limit switch signal fault, signal wrong report or some unusual condition occur, will cause the operation troubles of equipment.
(5) adopt the mode of signal self-insurance or the mode that adopts rest-set flip-flop set to control, sometimes because unusual or error signal cause the always set of certain signal, and program can't automatically reset to it, thereby affects the operation of equipment.If not for the analysis of program, can't find the reason of this fault, so general plant maintenance personnel can not in time fix a breakdown, and need to understand that the personnel of program process.Be unfavorable for like this control method safeguarded, prolong sometimes fault-time, enlarge fault effects, be unfavorable for the carrying out that produces.

Foundation with described spacing digital quantity point and the described highway section of the direction digital quantity point input mathematical model of obtaining, is exported the highway section digital quantity point of described equipment based on the highway section mathematical model of described spacing digital quantity point and direction digital quantity point through computing.
As an embodiment, described highway section mathematical model is:
Highway section digital quantity point=spacing digital quantity point+direction digital quantity point-2, wherein, when described equipment was the first traffic direction, described direction digital quantity point value was 1; When described equipment was the second traffic direction, described direction digital quantity point value was 2.
104, set according to step 101 with limit switch between highway section digital quantity point corresponding to highway section, the road section information of the equipment that obtains between limit switch.
According to the highway section digital quantity point of the described equipment of upper step output, and according to set with described limit switch between highway section digital quantity point corresponding to highway section, obtain the road section information of described equipment between described limit switch.
105, with the road section information that obtains and Real-time Collection to limit signal graphically show.
Lower mask body is introduced corresponding process:
Described method 100 can adopt two kinds of control models: manual mode and automated manner.Under manual mode, equipment can start and stop in any position.Under automated manner, the starting point of equipment and terminal point all must be on certain be spacing.
Referring to Fig. 6, fairly simple for the demonstration of " website " control among the figure, be exactly which limit switch equipment has met in the process of operation, the signal of this limit switch is through after certain time-delay, is transferred on the display unit to show.Having added a time-delay herein, is to be time of 1 in order to prolong limit signal, and this considers that mainly the time of touching limit switch during the equipment operation is sometimes very short, flashes across; Or less than refresh cycle of picture, and cause picture can not in time show spacing correct status; Be not easy to operating personnel to the assurance of the correct status of equipment operation.Delay time can be according to circumstances selected voluntarily, and for example 0 second, 200 milliseconds, or 1 second, 2 seconds etc.
Be implemented as follows;
If spacing 1 signal has come, time-delay triggers display unit " website 1 " signal so;
If spacing 2 signals have come, time-delay triggers display unit " website 2 " signal so;
If spacing 3 signals have come, time-delay triggers display unit " website 3 " signal so;
If spacing 4 signals have come, time-delay triggers display unit " website 4 " signal so;
If spacing 5 signals have come, time-delay triggers display unit " website 5 " signal so;
If spacing 6 signals have come, time-delay triggers display unit " website 6 " signal so;
If spacing 7 signals have come, time-delay triggers display unit " website 7 " signal so.
The core of the control flow among Fig. 6 is the demonstration control to " highway section "." highway section " shown three factors of main reference: (1) equipment limit switch that touches in service; (2) direction of equipment operation, equipment is herein made back and forth movement, so the traffic direction signal has two, these two signals all are collected in the input signal of the running status of equipment; What (3) select is automatic mode or manual mode, automatic mode must be rest in certain spacing on, and can stop at the optional position during manual mode.
For the locating and displaying in " highway section " of equipment operation, introduced formula of mathematical and controlled.Formula of mathematical is:
" highway section "=" spacing "+" traffic direction "-2
For this formula, at first need the digital quantity point of " spacing " and " traffic direction " input signal is carried out initialization definitions, specifically can be defined as follows:
If spacing 1 signal has come, the digital quantity point of " spacing " representative is 1 so;
If spacing 2 signals have come, the digital quantity point of " spacing " representative is 2 so;
If spacing 3 signals have come, the digital quantity point of " spacing " representative is 3 so;
If spacing 4 signals have come, the digital quantity point of " spacing " representative is 4 so;
If spacing 5 signals have come, the digital quantity point of " spacing " representative is 5 so;
If spacing 6 signals have come, the digital quantity point of " spacing " representative is 6 so;
If spacing 7 signals have come, the digital quantity point of " spacing " representative is 7 so;
If equipment moving direction 1 signal has come, the digital quantity point of " direction of motion " representative is 1 so;
If equipment moving direction 2 signals have come, the digital quantity point of " direction of motion " representative is 2 so.
According to the difference to the initialization definitions of the digital quantity point of " traffic direction " of " spacing ", " highway section " and equipment, need to revise or again selected this mathematical formulae.
System converts limit signal and the equipment moving direction signal that collects to digital quantity signal, participates in the mathematical operation of back.But, must after spacing 1 signal or spacing 2 signals or spacing 3 signals or spacing 4 signals or spacing 5 signals or spacing 6 signals or the arbitrary signal of spacing 7 signals have come, just begin mathematical operation; Otherwise " highway section " display remains unchanged.
Mathematical operation: " highway section "=" spacing "+" traffic direction "-2.
Before signal output, need to carry out initialization definitions to the digital quantity point of " highway section " output signal, concrete reality is as follows:
If " highway section " digital quantity is 1, trigger so display unit " highway section 1 " signal;
If " highway section " digital quantity is 2, trigger so display unit " highway section 2 " signal;
If " highway section " digital quantity is 3, trigger so display unit " highway section 3 " signal;
If " highway section " digital quantity is 4, trigger so display unit " highway section 4 " signal;
If " highway section " digital quantity is 5, trigger so display unit " highway section 5 " signal;
If " highway section " digital quantity is 6, trigger so display unit " highway section 6 " signal.
Then, according to " highway section " result of mathematical formulae computing, output signal triggers display unit and shows corresponding " highway section " signal.
In mathematical formulae " highway section "=" spacing "+" traffic direction "-2, the scope of " spacing " value is [1,7], the scope of " traffic direction " value is [1,2], so the scope of " highway section " value is [0,7], and the scope of actual highway section value is [1,6], calculated value just manys two states " 0 highway section " and " 7 highway section " than actual value like this, is about to extend about the highway section among Fig. 1.Only address this problem the signal output definition unit that needs in front and process and get final product, namely only define " highway section 1 " to " highway section 6 "; Although it is 0 or 7 that the mathematical formulae by the front can calculate " highway section ", do not have respective value to remove to trigger corresponding " highway section " state of display unit this moment.Be take 7 spacing situations as example, for N spacing situation, same method is processed herein.
Referring to Fig. 5 and Fig. 6, under automatic mode, suppose equipment according to direction of motion 2 operation, origin be the 2nd spacing, destination address be the 4th spacing, " traffic direction "=2 in mathematical formulae this moment then; When equipment be in operation touched the 3rd spacing, behind the spacing 30N signal of system delay, trigger display unit " website 3 " signal.Simultaneously, input system converts the signal that collects to digital quantity signal: " spacing "=3; In addition, flow process Rule of judgment " spacing signal parallel connection is 1 " satisfies (in fact among Fig. 6 at this moment, this condition is mainly used in manual mode, under the automatic mode can with reference to can be not yet with reference to), beginning computational mathematics formula: " highway section "=" spacing "+" traffic direction "-2=3+2-2=3, then the corresponding relation that defines according to signal output, the 3rd highway section can triggering display unit.
Then, equipment continues operation, touches next limit switch, and namely the 4th limit switch reached destination address, and equipment stops.The steering logic that press Fig. 6 this moment, " highway section 4 " is triggered, if this moment, equipment was parked on the limit switch, then " website 4 " state also is triggered, display unit all is triggered by " highway section 4 " and " website 4 ", the position of judgment device that can be very clear and definite; If broken through limit switch when equipment stops, becoming soon 0 after namely display unit " website 4 " state is triggered, this moment can by display unit " highway section 4 " state be triggered can judgment device the position.
Equipment moves under manual mode, and whether the equipment of need to considering stops on the limit switch.If, just as automatic mode.If not, namely equipment manually stopped at certain two spacing between, need the variation of consideration equipment " traffic direction " this moment, the change that brings to mathematical formulae.If equipment brings into operation from certain point in such as the environment of Fig. 1, from left to right, through the 3rd spacing after, manually stopped at the 3rd and the 4th spacing between, spacing owing to having triggered before the 3rd, satisfied " spacing signal parallel connection is 1 " this Rule of judgment, utilized mathematical formulae " highway section "=" spacing "+" traffic direction "-2=3+2-2=3, namely " the 3rd highway section " state all triggers and lights.After stopping, restarting equipment operation, two kinds of direction operations are just arranged, can be from left to right, also can be from right to left, variation just might occur in " traffic direction " in the mathematical formulae at this moment, thereby obtains two kinds of result of calculations, and in the reality, equipment or operation in " the 3rd highway section " are so Rule of judgment of needs this moment triggers the calculating of mathematical formulae, i.e. " spacing signal parallel connection is 1 " among Fig. 6.That is to say, only run into spacing after, " highway section " state just can change.
Referring to Fig. 5, Fig. 5 has shown a kind of positioning system 200 based on the operation of spacing equipment, can be regarded as the hardware system of realizing described method 100, and it comprises some limit switches that the path according to described equipment operation sets gradually, and also comprises:
