Detailed description of the invention
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the embodiment of the present invention below in conjunction with accompanying drawing.
Embodiment one
Refer to Fig. 1, it is the method flow diagram of a kind of middle low speed magnetic suspension train control method that the embodiment of the present application one discloses, and specifically comprises:
Step 101: the levitating current detecting suspension system;
Preferably, detected by the levitating current of current sensor collection suspension system.
Step 102: judge whether described levitating current is greater than rated value;
Step 103: when described levitating current is greater than default rated value, reduces the tractive force of straight line traction motor.
Medium-and low-speed maglev train relies on electromagnetic attraction that train is suspended into certain altitude, achieves train and contacts with the interorbital mechanical in place, then utilize linear electric motor train operation.The lift force of train suspension system is the attractive force controlling between the electromagnet that produced by the size of current of electromagnet and track by suspension system, and levitating electromagnet is positioned at the below of track, and therefore lift force relative to car body upwards, contrary with gravity direction.Suspension system, by the adjustment regulating levitating current size to realize lift force, makes lift force and keeps one to balance to ensure that train can normally suspend between train gravity and normal force.Therefore when normal force reduces, the lift force of suspension system also will reduce.When lift force reduces, levitating current needed for suspension system will just reduce, and the energy consumption of suspension system will reduce.
When described levitating current is greater than rated value, controls traction convertor according to control command and export to reduce tractive force; Cause the reduction of the normal force of straight line traction motor according to the reduction of described tractive force, and then described lift force is reduced, the reduction of described lift force causes the levitating current of suspension system to reduce.The tractive force size of conservative control linear electric motors, thus the normal force controlled in train travelling process is in the minimum value meeting system requirements all the time indirectly, suspension system needs the normal force overcome to reduce to cause the reduction of lift force, thus realizes the reduction of levitating current.
When described rated value refers to that locomotive dispatches from the factory, for the lowest high-current value that can bear of the normal job design of suspension system.When electric current overrate size, suspension system load is crossed conference and is caused suspension system job insecurity, can produce and build into the operating troubles that suspension is fallen a little and suspension power supply transships.
Can be found out by above-described embodiment: by judging the size of levitating current, when levitating current is greater than rated value, by reducing the size of tractive force thus reducing normal force, thus cause the reduction of lift force, final suspension system controls the reduction of levitating current, under making suspension system return to rated load, nominal load, solve because suspension system load is excessive cause the operating troubles that MagLev trainset train suspends a little and suspension power supply transships.
Embodiment two
Owing to implement in the one in low speed magnetic suspension train control method by judging levitating current whether off-rating, and then whether decision carries out the adjustment of tractive force.Changing because levitating current can be subject to the impact of several factors, is not only the levitating current change finally caused because the change of normal force causes the change of lift force.So more accurate in order to make judgement and control result, present invention also offers low speed magnetic suspension train control method in another kind, specifically refer to the method flow diagram shown in Fig. 2, specifically comprise:
Step 201: the normal force of detection of straight lines traction motor and the levitating current of suspension system;
Preferably, by the normal force of suspension controller detection of straight lines traction motor.
Under traction working condition, the normal force of straight line traction motor, measures by detecting device, also derives by the relation between tractive force, lift force, gravity.Certainly also detect by other modes, at this, which kind of detection mode of employing is not specifically limited, as long as can detect the size of normal force.
Preferably, detected by the levitating current of current sensor collection suspension system.
Step 202: judge whether described normal force is greater than predetermined threshold value, judges whether described levitating current is greater than rated value;
Step 203: when described normal force is greater than predetermined threshold value and described levitating current is greater than rated value, reduces the tractive force of straight line traction motor.
The lift force of suspension system is the attractive force controlling between the electromagnet that produced by the size of current of electromagnet and track by suspension system, and levitating electromagnet is positioned at the below of track, and therefore lift force relative to car body upwards, contrary with gravity direction.The normal force of so-called straight line traction motor is of outwardness in the linear electric motors power vertical with tractive force, is to act on the attractive force between the tablet on linear electric motors and track, identical with gravity direction.Suspension system, by the adjustment regulating levitating current size to realize lift force, makes lift force and keeps one to balance to ensure that train can normally suspend between train gravity and normal force.Change due to tractive force can cause the change of normal force, and when tractive force reduces, normal force will reduce thereupon, and when normal force reduces, the lift force of suspension system also will reduce.Required levitating current will just reduce, and the energy consumption of suspension system can reduce.
Because the size of the size of current and lift force that flow through levitating electromagnet in suspension system is proportional, suspension system is the control by controlling the size being realized lift force by the electric current of levitating electromagnet.Meanwhile, suspension system detects the distance between electromagnet and track by rang sensor, guarantees that suspension distance remains in a rational scope, thus realize the stable suspersion of train by Current adjustment.Suspension system, by the adjustment regulating the size of levitating current to realize lift force, makes lift force and keeps between train gravity and normal force balancing, to ensure that train normally suspends.Therefore, when the tractive force of straight line traction motor reduces, the normal force of linear electric motors will reduce thereupon, in order to ensure the normal suspension of locomotive, lift force can reduce along with the reduction of normal force, and final suspension system is by reducing levitating current to realize the reduction of lift force.
Can be found out by above-described embodiment: by judging whether the size whether size of normal force is greater than predetermined threshold value and levitating current is greater than rated value, determine whether reduction process is carried out to tractive force, reduction due to tractive force can cause the reduction of normal force, and then the lift force of suspension system will reduce, the levitating current of suspension system will reduce accordingly, by the reasonably optimizing between levitating current and tractive force, by polling power controlling in the reasonable scope, control to keep balancing between the normal force of generation when straight line traction motor runs and lift force.Such process can determine that the levitating current overrate of current suspension system causes because normal force is excessive more accurately, under such process can make suspension system return to rated load, nominal load, solve because suspension system load is excessive cause the operating troubles that MagLev trainset train suspends a little and suspension power supply transships, reduce the energy consumption of suspension system, improve the stability of suspension system work, to strengthen the practicality of medium-and low-speed maglev train.
