Description
Technical Field
The invention relates to the field of maglev trains, in particular to a method and a system for monitoring falling of an induction plate of a maglev train.
Background
At present, the main parts of a medium-low speed magnetic suspension traffic vehicle driven by a short stator linear motor at home and abroad comprise a track beam, a vehicle body, a suspension controller, a suspension frame module, an induction plate, a suspension electromagnet, a suspension sensor, an air spring, a linear motor primary part, an F track and the like.
The suspension principle of the existing magnetic suspension vehicle is as follows: the suspension electromagnet arranged on the suspension frame module generates exciting current after being electrified to form a controllable magnetic field, thereby generating electromagnetic attraction for attracting the F track. The electromagnetic attraction force is transmitted to the vehicle body through the air spring, so that upward supporting force is provided for the vehicle. The suspension controller continuously adjusts the working current of the suspension electromagnet according to the suspension gap value fed back by the suspension sensor, so that the electromagnetic attraction between the suspension electromagnet and the F track is continuously adjusted, the gap between the suspension electromagnet and the F track is kept stable, and the stable suspension of the train is realized.
The prior magnetic suspension vehicle has the following disadvantages: the induction plate is usually installed on the upper surface of the F rail in a bonding and bolt fastening mode, the vehicle rail coupling vibration can be caused when a vehicle runs on the rail, the induction plate and the F rail are made of different materials and have different thermal expansion coefficients, and after the induction plate is subjected to the action of outdoor environmental factors such as sunshine, rain and the like for years, the bonding and fastening of the induction plate can be failed, so that the induction plate falls off from the F rail. Considering that the train runs in a long-distance line, a device and equipment for directly monitoring the falling of the aluminum induction plate are not suitable to be arranged along the line. Especially, full automatic driving train, no driver watch the control, can only discover unusually when the machineshop car was overhauld at night routinely, consequently can't discover and eliminate the tablet at the very first time and drop the trouble, bring danger for driving safety.
Disclosure of Invention
In order to solve the problem that the prior art cannot find and eliminate the falling fault of the induction plate at the first time and bring danger to the driving safety in the background technology, the invention provides a method for monitoring the falling of the induction plate of a maglev train, and the specific technical scheme is as follows.
A method for monitoring the falling of an induction plate of a maglev train comprises the following steps:
s1, judging whether the output current of each suspension controller is larger than a preset current or not;
if the output current of a certain suspension controller is larger than the preset current, jumping to S2;
s2, judging whether the output currents of all the suspension controllers positioned behind the same side of the suspension controller with the output current larger than the preset current are larger than the preset current or not;
if yes, judging that the induction plate has a falling fault;
if not, returning to S1;
the value range of the preset current is 2-3 times of the normal output current value of the suspension controller. The inventor researches and discovers that when the induction plate falls off, due to the fact that only the acting force of the primary part of the linear motor and the F track is expressed as attractive force, the repulsive force of the suspension normal force is partially lost, the original force balance is broken, the force difference is enlarged, the output current of the suspension controller is increased sharply, and the inventor discovers that the increasing amplitude is 2-3 times of the normal amplitude through research. Based on the principle, the method provided by the invention can judge the falling fault of the induction plate by monitoring the output current of the suspension controller. When the output current of each levitation controller exceeds the predetermined current, it may be caused by instability of the levitation control itself, and therefore it is necessary to continuously monitor whether all the levitation controllers on the same side exceed the predetermined current. If the levitation controllers on the same side exceed the preset current, the shedding situation can be judged, and the output currents of all the levitation controllers on the same side of the train are obviously characterized in that the output currents of all the levitation controllers do not have the characteristic, so that the possibility of misjudgment does not exist.
Preferably, step S3 is further included after S2, a corresponding vehicle driving distance is obtained when the output current of the levitation controller is greater than the preset current, and the specific position where the sensing plate falls off is obtained. When the output current of the suspension controller is larger than the preset current, the induction plate corresponding to the position of the suspension controller falls off, and therefore the specific position where the induction plate falls off can be obtained by obtaining the corresponding vehicle driving mileage when the output current of the suspension controller is larger than the preset current.
Preferably, step S4 is further included after S3, the occurrence time of the sensing board falling fault and the specific position of the sensing board falling are sent to the dispatching center. Therefore, the fault type and the fault position can be found at the first time and processed in time, and the influence on the safe operation of the vehicle is avoided.
Based on the same inventive concept, the invention also provides a magnetic-levitation train induction plate falling monitoring system, which comprises:
the suspension controller current monitoring module is used for acquiring the output current of each suspension controller;
and the control module is used for judging whether the output current of each suspension controller is greater than the preset current or not, and judging that the induction plate falls off when the output current of one suspension controller is greater than the preset current and the output currents of all the suspension controllers positioned behind the same side of the suspension controller are greater than the preset current. The value range of the preset current is 2-3 times of the normal output current value of the suspension controller.

Preferably, the device further comprises a fault position acquisition module, which is used for acquiring the corresponding vehicle driving mileage when the output current of the levitation controller is greater than the preset current, so as to obtain the specific position of the sensing plate falling. When the output current of the suspension controller is greater than the preset current, the sensing plate corresponding to the position of the suspension controller falls off, and therefore the specific position where the sensing plate falls off can be obtained by obtaining the corresponding vehicle driving mileage when the output current of the suspension controller is greater than the preset current.
Preferably, the system further comprises a fault reporting module, which is used for sending the occurrence time of the sensing board falling fault and the specific position of the sensing board falling to the dispatching center. Therefore, the fault type and the fault position can be found at the first time and processed in time, and the influence on the safe operation of the vehicle is avoided.
