Description
Technical field
The utility model belongs to harbour facilities technical field more particularly to a kind of stockyard single machine traveling correction system.
Background technique
Using a traveling means for correcting close to switch form on the stacker at conventional harbour, for conventional harbour
Stockyard single machine traveling means for correcting.There is one on the single machine of stockyard close to switching, has a metal for every 100 meters on ground rail beam
It meets and discusses.When equipment is moved on ground metal meets and discusses, when meeting and discussing close to switch close to metal, signal will be sensed close to switch
And signal is transmitted to PLC system, PLC output module respective point becomes 0 by 1.There is first to meet and discuss at 0 point of track girder, track
There is second to meet and discuss at 100 meters of beam, there is third to meet and discuss at 200 meters of track girder ..., and so on have the at the n-th hundred meters of track girder
N+1 are met and discussed.PLC system remembers which brief meeting calculates corresponding position, assigns corresponding rice number to traveling encoder
Value is got up traveling corrective action using this principle.
Multiple traveling means for correctings close to switch form are also referred to as gray code format traveling means for correcting.Gray code is phase
Two adjacent numbers, only one position changes in binary digit.1 Gray code list: 0,1,2 Gray code list: 00,01,
11,10 3 Gray code lists: 000,001,011,010,110,111,101,100 ..., and so on.1 Gray code totally 2
A different value, 2 Gray codes totally 4 different values, 3 Gray codes totally 8 different values, the total 2^n different value of n Gray codes.Heap
Several close switches just corresponding several Gray codes are installed on traveling means for correcting on the single machine of field.The traveling of stockyard single machine corrects two o'clock
The stockyard distance l=single machine distance travelled L/ (2^n-1).The frequency and l of traveling correction are inversely proportional, and l and n are inversely proportional, traveling
The frequency and n of correction are directly proportional.N must be increased to improve the accuracy of distance travelled detection, that is, close open is installed more
The quantity of pass.The cost of early investment and the fault point of equipment also will increase.When there are three close switches, close to switch detection
At 001 point of 0 meter of correspondence, close to 011 point of l meter corresponding place of switch detection, it is close switch detect 010 point it is 2l meters corresponding at, successively class
It pushes away.
Said one close to switch form traveling means for correcting the advantages of: it is at low cost, traveling correct system only one
Close to switch, the metallic support of every 100 meters of welding one.Structure is simple, and mounting means is simple, and maintenance is convenient, daily only to one
It is a to be checked close to switch；The shortcomings that one traveling means for correcting close to switch form: maintenance rate is high, usually will be to each
A metal, which is met and discussed, to be checked, if n-th of metal meet and discuss deform close to switch can't detect when, stockyard single machine goes to n+
It is that n-th of position of meeting and discussing, at this time detecting distance and actual range differ 100 meters that 1 single machine of stockyard when meeting and discussing, which will be considered that, and stockyard is single
The system of machine testing traveling position can quote failure.Accuracy is low, every 100 meters just once traveling corrections, stockyard on track girder
Single machine position in stockyard is detected when single machine is between two metals are met and discussed can only lean on traveling encoder, set when encoder breaks down
The standby position that cannot detect stockyard single machine, two equipment on a possible track girder bump against in this case.Therefore
Barrier rate is high, and metal, which is met and discussed, to be simply mounted on track girder, slightly has external force that will deform, and restoring not in time will
There is the case where top is mentioned.And close metal can all be responded close to switch, when equipment is mobile in n-th and n+1 gold
When belonging between meeting and discussing, stockyard single machine will be considered that (n+1)th close to after switching a close metal and respond when equipment is goed ahead
The position that a metal is met and discussed.Traveling detection system can quote failure at this time.
The shortcomings that traveling means for correcting of above-mentioned gray code format: there is the shortcomings that meeting and discussing " can only lack cannot be wrong ".Such as connect
There are three nearly switches, close to 001 point of 0 meter of correspondence of switch detection place, close to 011 point of switch detection it is l meters corresponding at, close switch is examined
Survey 010 point it is 2l meters corresponding at, close to 110 points of switch detection it is 3l meters corresponding at when being deformed close to switching damage or meet and discuss 011
It meets and discusses when becoming 001 and meeting and discussing, stockyard single machine, which goes to 011, which reads 001 when meeting and discussing, to be assigned to distance travelled detection system 0 meter
System, detecting distance and actual range differ l meters at this time, and the system of stockyard single machine detection traveling position can quote failure.When the 011st
Meet and discuss when lacking close to switch can't detect when, only can exist the 011st meet and discuss when locating without traveling correct, there is no give away
Row distance detection device assigns the case where wrong value.
