Description
Technical field
The present invention relates to a kind of electric locomotive, motor-car monolever multi-mode control method, belong to locomotive driving actuation means and method class.
Background technology
When main line railway electric locomotive, motor-car operation, the master instruction controller---driver controller is set the height of the size and the limited speed of tractive force to the driver by handling, thereby reaches the purpose of regulating train running speed.In order to reach above-mentioned regulation and control purpose, the regulate and control method of home and abroad use at present has two kinds.One, it is the dual-handle driver controller that generally adopts with Europe, promptly this controller has two bar handles, one of them is used to set the size of tractive force by microcomputer, another sets the height of restriction running velocity by microcomputer, its control method both can have level, also can be stepless; Its step-less adjustment realizes that by changing the potential device output voltage having level to regulate then is by changing the incompatible realization of contact bank.Domestic what generally use is the monolever driver controller, and it directly sets the height of locomotive operation limited speed by handle, and the size of tractive force then is to provide indirectly by certain Characteristics Control algorithm.
In design function and practical effect contrast: the dual-handle driver controller obviously is better than the monolever driver controller, it has, and tractive force is regulated steadily, the locomotive impulsion is little, the sleet sky is difficult for advantages such as idle running, but there are inherent defects such as mechanism's complexity, cost of manufacture height, volumetric spaces be big again in it; Monolever driver controller by contrast, its advantage is simple in structure, cost of manufacture is low, volumetric spaces is little, but its greatest drawback then is: owing to can't realize the setting of artificial tractive force, and it is bigger to make locomotive control impulsion, the sleet sky easily dallies.
Therefore, can find and propose a kind of simple and easy driver controller and control method of taking into account above-mentioned both advantages, thereby realize the idealized of electric locomotive, motor-car speed adjusting performance and tractive force regulation and control; This has been a kind of expectation of domestic relevant industries scientific research and production, utilization department.
Summary of the invention
Purpose of the present invention: the monolever driver controller and the control method thereof that are intended to propose a kind of hold concurrently all dual-handle and monolever driver controller common advantage.
This electric locomotive, motor-car monolever multi-mode control method, it is characterized in that: it is by on the basis of existing monolever controller, between the microcomputer of this monolever controller and original joint control, increase two select switches and a corresponding microcomputer entrance point, and the Characteristics Control software in the microcomputer is made amendment with two selection functions; By two select switches on former monolever driver controller, setting up, make two select switches and monolever driver controller realize two kinds of different controller characteristic curves of former dual-handle control setup by two kinds of different connection approach; One links by the control system that limits locomotive speed in contact, position, " 0 " on the select switch (or " 1 ") and the microcomputer, allows locomotive enter the limiting operation state; Its two control system by the setting locomotive tractive effort on contact, position, " 1 " on the select switch (or " 0 ") and the microcomputer links, and allows locomotive enter Ideal Traction power running state.
" a kind of electric locomotive motor-car monolever multi-mode control method " according to above technical scheme proposition, compare with two kinds of driver controllers that generally use both at home and abroad now, its advantage is: both kept the advantage that domestic monolever driver controller is simple in structure, cost is low, volumetric spaces is little, simultaneously allow it have the operating characteristic of external dual-handle driver controller again, the speed limit regulation and control can be artificially realized, artificial tractive force setting regulation and control can be realized again very easily; Shortcomings such as the locomotive impulsion is big in order to overcome, the easy idle running in sleet sky find a desirable technique solution.
Description of drawings
Accompanying drawing 1 connects scheme drawing for monolever multi-mode control setup of the present invention;
Accompanying drawing 2 is the schematic flow sheet of controlling of the control method that the present invention relates to;
Accompanying drawing 3 is domestic locomotive monolever driver controller scheme drawing;
Accompanying drawing 4 is external dual-handle driver controller scheme drawing.
Among the figure: 1-driver controller, two select switches of 2-, 3-microcomputer.
The specific embodiment
This electric locomotive, motor-car monolever multi-mode control method that the inventor proposes are a kind of foolproof technical schemes: it only is to increase a select switch 2 and a corresponding microcomputer entrance point more than two or two on the existing domestic monolever driver controller 1 that generally uses, and again the Characteristics Control software that microcomputer Central Plains has been imported is carried out a few modifications just.
Its specific practice is: a multidigit change-over swith 1 is set on the electric locomotive motor-car of monolever driver controller.Be example with two position conversion switch below, described this two position conversion switch are provided with " 0 " or " 1 " two kinds of switching states, just can realize different controller characteristic curves by selecting different states.Its simplest way is: state " 0 " (or " 1 ") is set the height of limited speed, promptly enters limiting operation, this moment tractive force by microcomputer 3 according to train real-world operation speed with set limited speed relatively finish automatically regulating; State " 1 " (or " 0 ") is set control tractive force size, and can not consider limited speed (can be considered as ∞) this moment.
Yet, the manipulation custom of considering existing main line railway driver is difficult to change for the moment, preferably can take into account existing manipulation controller characteristic curve, therefore the inventor advises adopting following setting: state " 0 " (or " 1 ") is that handle is kept existing controller characteristic curve (as the accurate constant speed of the constant current of handing over straight electric locomotive or the permanent torque constant velocity characteristics of friendship orthogonal electric locomotive), state " 1 " (or " 0 ") is that handle is set at and controls the tractive force size, it is steadily adjustable that the largest benefit of doing like this is that tractive force applies, the locomotive impulsion is less, and the sleet sky is difficult for idle running.
The above-mentioned this monolever driver control system that has two select switches setting up makes monolever driver controller after the improvement locomotive control characteristic under handling can be in two kinds of alternative regulation and control states (seeing accompanying drawing 2) simultaneously.From this control flow block diagram as can be seen: when two select switches 2 switch to " 0 " state, this moment, handle was in " speed control mode " of control rate size, allow locomotive in microcomputer, be in the comparison state of a control of limited speed under the instruction of individual features Control Software, locomotive is moved with the speed after regulating according to instruction; And when two select switches 2 switched to position, " 1 " (or " 0 "), this moment, handle was in " the Torque Control pattern " of setting the tractive force size, moved under the tractive force effect after the adjusting according to instruction thereby be directed at locomotive.
In technique scheme, if when two select switches selecting are multidigit select switches more than two, not only can realize the dual mode operated of dual-handle driver controller with the monolever controller, can also realize more regulation and control model; But, adopt two select switches just can satisfy the execute-in-place requirement according to existing locomotive operation regulation and control requirement.
About modification problem to Characteristics Control software; In present monolever driver controller control system, though the monolever driver controller can directly be set the size of limited speed, tractive force can only convert by certain indirect algorithm and draw.Handing over the accurate constant velocity characteristics of constant current of straight electric locomotive with SS8 is example, when handle is adjusted to the n=16 level, the expression train running speed is no more than 160km/h, but the size of tractive force depends at that time speed v and level n, represent armature electric current I a (A)=Min (120n of tractive force size, 875n-87.5v, 1450) and must not surpass maximum current envelope restraining line in the full range of speed of motor, be that tractive force depends on the convert size of the value that obtains of above-mentioned characteristic, numerical value can be from 0 until maximum permissible value, the conversion driver of this complexity can't predict and control, and therefore can not artificially set the size of tractive force; And this also may cause the locomotive impulsion big just, and the sleet sky is prone to the major reason of phenomenon generations such as idle running.And after adopting two select switches, when change-over switch was in position, " 0 " (or " 1 "), its Characteristics Control software only played the instruction effect to setting the speed limit degree; And when change-over switch was in position, " 1 " (or " 0 "), its Characteristics Control software was also only regulated the setting of tractive force and is worked; To be the common software personnel make a few modifications to system of existing monolever driver modulator function software to this regulation and control form can realize.
