Description
Technical field
The present invention relates to a kind of motor control assembly of rail vehicle, is a kind of three phase electric machine rotation direction specifically
Control device.
Background technology
Rail traffic vehicles door system is to be related to train operation and the product of personal safety, the crucial security of the product
It is required that when being train operation, it is necessary to ensure that door system is in reliable locking states.Rail traffic vehicles door system, which is realized, to open the door
Or the controlled motor closed the door mainly has two types：Brush direct current motor and DC brushless motor.Brush direct current motor belongs to
Two-phase induction motor, DC brushless motor belong to three phase electric machine.There is cost than relatively low using brush direct current motor, be simple to manufacture, hold
Manageable feature.When brush direct current motor is used for into the control of train-door system, generally use " H " bridge control structure, such as Fig. 2
It is shown, one of passage is disconnected using relay in " H " bridge, for example disconnect M1, M4 passage so that electric current can only flow through
M2, M3 passage.Thus brush direct current motor is easier to meet above-mentioned requirements, but the structure of brush direct current motor limits,
The brush in motor must be regularly replaced, the maintenance cost of product is higher.Brush is not regularly replaced using brushless electric machine
It is required that operated but a disadvantage is that can not easily be controlled as brush direct current motor toward same direction.It is as shown in figure 3, right
When DC brushless motor is controlled, the Partial Power switching tube of driver is opened, other power switch pipes is simultaneously closed off, passes through
Change to open and can realize different rotation directions from the order closed.Motor rotation direction depend on open power switch pipe
Various combination, and the order of adjacent combination.
The enabled pin of power drive device is the precondition that controlled motor operating must is fulfilled for, by controlling this enabled
The level signal of pin, it is possible to achieve limit the rotation direction of motor.
In the prior art, it is conventional scheme using the control of software progress motor rotation direction.How software matter is ensured
The problem of amount is one extremely complex, for software integrity after certain level is brought up to, the efficiency of input will become very low.But
It is that the reliability of hardware circuit then reaches very high level easily by appropriate design method.
Personal safety of the rotation direction of rail traffic vehicles door system for ensureing passenger is extremely important.In train operation
When, move and be allowed to shutdown direction, the motion to enabling direction is definitely forbidden.If the rotation direction of motor obtains
Less than effective control, the personal safety of passenger is on the hazard.
The content of the invention
Goal of the invention：It is an object of the invention to provide the track vehicle door system that a kind of safety coefficient is high, complexity is low
Rotation direction control method.
Technical scheme：The present invention is realized by following technological means：A kind of three-phase DC motor rotation direction control
Device, including power model, power drive device, programmable controller, restriction control module, the programmable controller connection
Power drive device, power drive device connection power model, power model connection motor, set location encodes on motor
Device, position coder are connected with limiting control module.
Six kinds of status informations and two rotation direction information, each status information corresponding electricity are set in the restriction control module
Angle position residing for machine rotor, each rotation direction information correspond to the rotation direction of motor.
The logic for limiting control module and obtaining position coder in real time, and carried out with oneself state information with contrast
Compared with so as to obtain the rotation direction information of motor.
The rotation direction information for limiting control module output is input to power drive device, the carry out rotation direction limit to motor
It is fixed.
Beneficial effect：Compared with prior art, the invention causes three phase electric machine being used for control door system the present invention
Security performance be easier obtain.Door system can not be opened this requirement when vehicle is run, and depend not only upon software control,
Also ensured simultaneously by limiting control module using hardware, so play the effect of double shield.And vehicle it is out of service when,
Door system normally can open the door or close the door.Door system need not increase extra electric device and carry out redundancy to locking system
Design, has been able to the security of guarantee system, thus can reduce software development and material cost.

Embodiment
The present invention is described in further detail with reference to Figure of description：
The present invention relates to a kind of control system of the direction of motion of three phase electric machine, as shown in figure 1, it include power model,
Power driver module, programmable controller, control module is limited, the programmable controller connects power drive device, power
Driving element connects power model, and power model connection motor, the set location encoder on motor, position coder is with limiting
Control module is connected.
As shown in figure 4, because DC brushless motor is typically taken turns to operate to motor by six power tubes in the running
Direction is controlled, therefore six kinds of status informations and two rotation direction information are set in control module, and each status information is corresponding
Angle position residing for rotor, each rotation direction information correspond to the rotation direction of motor.When rotor is in some
During angle position, the position coder of motor sends status information to restriction control module.
The logic for limiting control module and obtaining position coder in real time, and carried out with oneself state information with contrast
Compared with.It is respectively S1-S6 that specifically we, which define 6 states, then motor rotation direction must be S1, S2 ... S6 or S6,
S5 ... S1, the logic of control module built-in motor operating first is limited, is changed when such as rotating forward for S1, S2 to S6, and it is anti-
Changed when turning for S6, S5 to S1, when status information, which is delivered to, limits control module, module reads information and matched, state
Information is sent to successively in sequence, the order being sent to according to status information, can be limited control module and be may determine that electricity
The rotation direction of machine, limit control module and send the instruction level signal of rotation direction to power drive device, analog line driver
If part receives the level signal for forbidding operating, power model is controlled to stop power supply at once, motor stops.
