Description

Technical Field

[0001] The present invention relates to the technical field of maglev train control, and in particular to a maglev train parking system and method. Background Art

[0002] Maglev trains rely on electromagnetic attraction to suspend the vehicle to a certain height, so that there is no mechanical contact between the vehicle and the ground track. The electromagnetic attraction generates a guiding force, and the traction force generated by the linear motor drives the train, fundamentally overcoming the adhesion limitation of wheel-rail trains. The biggest feature of maglev trains is that they achieve contactless operation, which is also the biggest difference and advantage between maglev trains and wheel-rail trains.

[0003] When a maglev train is being debugged on a test line, running on the main line or at some stations, the train may rush to or run out of the end of the line due to a train system failure or the driver's inattention. In the worst case, the train may be damaged or people may die, causing significant economic losses.

[0004] Currently, because maglev trains maintain a certain clearance from the ground during operation and the suspension system is significantly affected by mechanical braking forces, excessive application of emergency braking can easily cause vehicle instability. Current suspension control technology is unable to address the technical challenge of preventing train instability under emergency braking. Therefore, simply applying emergency braking when a train shows signs of over-advancement is not suitable for preventing over-advancement and emergency stopping maglev trains. Furthermore, existing maglev train parking systems are susceptible to weather conditions and rely too heavily on ground-based systems.

[0005] Therefore, it is an urgent problem for those skilled in the art to provide a maglev train parking system and method that is not affected by weather and does not rely too much on ground devices, can avoid the adverse consequences of the train running out of the end of the line, and effectively improves the overall safety and stability of the train. Summary of the Invention

[0067] The embodiments of the present invention are written in a progressive manner.

[0068] The embodiments of the present invention provide a maglev train parking system and method, which primarily address the technical problems in the prior art that train parking systems are susceptible to weather influences or overly rely on ground devices, and may cause trains to run off the end of the line.

[0076] The signal execution module is used to execute the corresponding parking operation according to the judgment result.

[0077] The maglev train parking system provided by the present invention is provided with a ground parking trigger device and an onboard parking control device. The onboard parking control device includes a signal receiving module, a signal judgment module, and a signal execution module. The signal receiving module is connected to the ground parking trigger device, and the signal judgment module is connected to the signal receiving module and the signal execution module, respectively. During operation, when the train travels on the track, the signal receiving module in the onboard parking control device installed on the train receives a stop signal sent by the ground parking device installed on the track surface. The signal receiving module sends the stop signal to the signal judgment module. The signal judgment module determines the type of stop signal and sends the judgment result of the stop signal type to the signal execution module. At the same time, the signal judgment module compares the current train speed with a preset speed threshold to determine whether the current train speed exceeds the speed threshold and sends the speed judgment result to the signal execution module. The signal execution module performs a corresponding stop operation based on the speed judgment result. The signal execution module also performs a corresponding stop operation based on the judgment result of the stop signal type.

[0078] like Figure 2 As shown, preferably,

[0079] The ground parking trigger device includes: a first signal trigger device, a second signal trigger device and a third signal trigger device;

[0080] The signal receiving module is connected to the first signal triggering device, the second signal triggering device and the third signal triggering device respectively;

[0081] The types of parking signals include: quick brake signal, emergency brake signal and landing brake signal;

[0082] a first signal triggering device, configured to send a rapid braking signal to the signal receiving module under a first triggering condition;

[0083] a second signal triggering device, configured to send an emergency braking signal to the signal receiving module under a second triggering condition;

[0084] The third signal triggering device is used to send a vehicle landing brake signal to the signal receiving module under a third triggering condition.

[0085] During actual operation, the ground parking trigger device is equipped with a first signal trigger device, a second signal trigger device, and a third signal trigger device; the signal receiving module is connected to the first signal trigger device, the second signal trigger device, and the third signal trigger device respectively; and the parking signal includes three types, specifically a rapid braking signal, an emergency braking signal, and an alighting braking signal. During operation, the three signal trigger devices in the ground parking trigger device are set with different trigger conditions. When the first trigger condition is met during the train's travel, the first signal trigger device sends a rapid braking signal to the signal receiving module; when the second trigger condition is met during the train's travel, the second signal trigger device sends an emergency braking signal to the signal receiving module; when the third trigger condition is met during the train's travel, the third signal trigger device sends an alighting braking signal to the signal receiving module.

[0086] like Figure 3 As shown, preferably, the first signal triggering device includes: a first signal sensing sub-device and a first signal emitting sub-device;

[0087] The first sensing sub-device is used to sense the current running speed of the train and obtain a first interval distance between the current train and the first sensing sub-device;

[0088] The first signal transmitting sub-device is configured to send a rapid braking signal to the signal receiving module when the first interval distance is greater than a first distance threshold.

[0089] In actual operation, the first signal triggering device is provided with a first signal sensing sub-device and a first signal emitting sub-device. The first sensing sub-device is used to sense the current train speed and obtain a first distance between the current train and the first sensing sub-device. The first signal emitting sub-device is connected to the first signal sensing sub-device. When the first distance obtained by the first sensing sub-device exceeds a pre-set first distance threshold, the first signal emitting sub-device transmits a rapid braking signal to the signal receiving module. During operation, the first sensing sub-device senses the current train speed and transmits the current train speed to the first signal emitting sub-device. At the same time, the first sensing sub-device obtains the first distance between the current train and the first sensing sub-device and transmits the first distance to the first signal emitting sub-device. After obtaining the current train distance, the first signal sensing sub-device transmits the current train distance to the signal judgment module (or obtains the current train speed through the train's own speed display device). When the first distance exceeds the first distance threshold (i.e., the first trigger condition), the first signal emitting sub-device transmits a rapid braking signal to the signal receiving module.

[0090] like Figure 3 As shown, preferably, the second signal triggering device includes: a second signal sensing sub-device and a second signal emitting sub-device;

[0091] The second sensing sub-device is used to sense the current running speed of the train and obtain a second interval distance between the current train and the second sensing sub-device;

[0092] The second signal transmitting sub-device is configured to send an emergency braking signal to the signal receiving module when the first signal transmitting sub-device fails and the second interval distance is greater than a second distance threshold.

[0093] In actual operation, the second signal triggering device is provided with a second signal sensing sub-device and a second signal transmitting sub-device. The second sensing sub-device is used to sense the current train speed and simultaneously obtain a second distance between the current train and the second sensing sub-device. The second signal transmitting sub-device is connected to the second signal sensing sub-device. When the second distance obtained by the second sensing sub-device exceeds a pre-set second distance threshold, the second signal transmitting sub-device transmits a rapid braking signal to the signal receiving module. During operation, the second sensing sub-device senses the current train speed and transmits the current train speed to the second signal transmitting sub-device. At the same time, the second sensing sub-device obtains the second distance between the current train and the second sensing sub-device and transmits the second distance to the second signal transmitting sub-device. After obtaining the current train distance, the second signal sensing sub-device transmits the current train distance to the signal judgment module (or obtains the current train speed through the speed display device on the train). When the second distance is greater than the second distance threshold and the first signal transmitting sub-device fails (i.e., the second trigger condition), the second signal transmitting sub-device sends an emergency braking signal to the signal receiving module.

[0094] like Figure 3 As shown, preferably, the third signal triggering device includes: a third signal sensing sub-device and a third signal emitting sub-device;

[0095] a third sensing sub-device, configured to sense a current train running speed and obtain a third interval distance between the current train and the third sensing sub-device;

[0096] The third signal transmitting sub-device is used to send a vehicle landing brake signal to the signal receiving module when both the first signal transmitting sub-device and the second signal transmitting sub-device fail and the third interval distance is greater than a third distance threshold.

[0097] In actual operation, the third signal triggering device is provided with a third signal sensing sub-device and a third signal transmitting sub-device. The third sensing sub-device is used to sense the current train speed and simultaneously obtain a third distance between the current train and the third sensing sub-device. The third signal transmitting sub-device is connected to the third signal sensing sub-device. When the third distance obtained by the third sensing sub-device exceeds a pre-set third distance threshold, the third signal transmitting sub-device transmits a rapid braking signal to the signal receiving module. During operation, the third sensing sub-device senses the current train speed and transmits the current train speed to the third signal transmitting sub-device. Simultaneously, the third sensing sub-device obtains the third distance between the current train and the third sensing sub-device and transmits the third distance to the third signal transmitting sub-device. After obtaining the current train distance, the third signal sensing sub-device transmits the current train distance to the signal judgment module (or obtains the current train speed through the speed display device on the train). When the third distance is greater than the third distance threshold and both the first signal transmitting sub-device and the second signal transmitting sub-device fail (i.e., the third trigger condition), the third signal transmitting sub-device transmits a landing brake signal to the signal receiving module.

[0098] Preferably, the first signal triggering device is further used to: send a rapid braking signal to the signal receiving module when the current train running speed is greater than a speed threshold.

[0099] During actual use, after the first, second and third signal sensing sub-devices send the current travel distance of the train to the signal judgment module (or obtain the current speed of the train through the speed display device in the train), the signal judgment module determines whether the current train running speed is greater than the speed threshold (i.e., the overspeed judgment result). If so, the judgment result is fed back to the first signal triggering device. After receiving the overspeed judgment result, the first signal triggering device sends a rapid braking signal to the signal receiving module; the rapid braking signal is transmitted to the signal execution module via the signal receiving module and the signal judgment module, and the signal execution module performs the rapid braking operation.

[0100] like Figure 4 As shown, preferably, the vehicle-mounted parking control device further includes: a bypass module;

[0101] The bypass module is arranged between the signal receiving module and the ground parking trigger device;

[0102] The bypass module is used to shield or cut off the stop signal sent by the ground stop trigger device when the train is running normally or abnormally.

[0103] In actual operation, a bypass module is also provided, which is arranged between the signal receiving module and the ground stop trigger device. During operation, if the train is operating normally, the current speed does not exceed the speed threshold, and the first, second, and third trigger conditions are not met, then the ground stop trigger device mistakenly sends a stop signal. The bypass module can shield or cut off the stop signal sent by the ground stop trigger device. After shielding or cutting off the stop signal, the train can continue to operate normally. If the train is operating abnormally and the trigger condition is met to trigger the stop signal, that is, the train is in the braking state or the landing state, the bypass module can shield or cut off the stop signal sent by the ground stop trigger device. After shielding or cutting off the stop signal, the train can continue to operate normally.

[0104] like Figure 5 As shown, preferably, the signal execution module includes: a rapid braking submodule, an emergency braking submodule and an alighting braking submodule;

[0105] A rapid braking submodule, configured to perform a rapid braking operation according to a rapid braking signal;

[0106] An emergency braking submodule, configured to execute an emergency braking operation according to an emergency braking signal;

[0107] The landing brake submodule is used to perform the landing brake operation according to the landing brake signal;

[0108] The rapid braking deceleration used during the rapid braking operation is a,

[0109] The emergency braking deceleration used during the emergency braking operation is b.

[0110] The deceleration rate of the vehicle braking during the vehicle braking operation is c.

[0111] a=b≤c.

[0112] During actual use, the signal execution module is provided with a rapid braking submodule, an emergency braking submodule and a landing braking submodule, which correspond to different types of parking signals respectively. During operation, the decelerations used for rapid braking and emergency braking are a and b respectively, while the deceleration used for landing braking is c. The relationship between them is a=b≤c. Rapid braking and emergency braking are applicable to milder situations, and the required deceleration is lower than the deceleration of landing braking. The situation of landing braking is more critical and requires a higher deceleration. In this embodiment, rapid braking is specifically electric braking, emergency braking is specifically air braking, and landing braking is specifically when the vehicle loses suspension and falls and friction is achieved by the skid.

[0113] like Figure 6 As shown, preferably,

[0114] The distance between the first signal triggering device and the second signal triggering device is S1;

[0115] The distance between the second signal triggering device and the third signal triggering device is S2;

[0116] The distance between the third signal triggering device and the end of the track where the train is currently traveling is S3;

[0117] The maximum running speed of the train is preset as Vmax, and the safe length of the current track of the train is preset as S0;

[0118] Among them, the values of S1, S2 and S3 satisfy: S1+S2+(S3-S0)≥V 2 max / 2a.

[0119] During actual application, the distances between the first signal trigger device, the second signal trigger device, the third signal trigger device and the end of the current travel track are defined as S1, S2 and S3 respectively. The maximum operating speed of the train is preset as Vmax, and the safe length of the current travel track of the train is S0. Then the relationship between S1, S2, S3 and S0, the maximum operating speed of the train and the deceleration of rapid braking satisfies the above formula.

[0120] A method for parking a magnetic levitation train comprises the following steps:

[0121] S1 obtains the parking signal sent by the ground parking trigger device;

[0122] S2. Get the current train speed and preset the speed threshold;

[0123] S3 determines the type of stop signal and determines whether the current train speed is greater than the preset speed threshold;

[0124] S4. Execute corresponding parking operations based on the judgment result.

[0125] In step S1, the onboard parking control device in the maglev train obtains a parking signal sent by the ground parking trigger device;

[0126] In step S2, the onboard parking control device obtains the current train running speed and presets a speed threshold;

[0127] In step S3, the onboard parking control device determines the type of the parking signal and whether the current train running speed is greater than a preset speed threshold, and generates a plurality of types of parking signal determination results and a speed determination result;

[0128] In step S4 , the vehicle-mounted parking control device performs corresponding parking operations according to the judgment results of the multiple types of parking signals and the speed judgment result.
