Illustratively, the hydraulic brake system comprises a brake control unit 44, a hydraulic control unit and a brake execution unit, wherein the brake control unit 44 is used for generating an emergency brake signal when the emergency brake control circuit is disconnected, the hydraulic control unit is used for transmitting required hydraulic brake force to the brake execution unit according to the emergency brake signal, and the brake execution unit is used for converting the hydraulic brake force into mechanical brake force to realize braking.
For example, the brake control unit 44 includes an electronic control unit and an electromagnetic valve, the hydraulic control unit includes a hydraulic drive cylinder, and the brake execution unit includes a brake caliper; furthermore, the hydraulic brake system comprises an accumulator for supplying oil. In the working process, the electronic control unit is used for controlling the electromagnetic valve to lose power when emergency braking is applied, the energy accumulator is communicated with the hydraulic driving oil cylinder when the electromagnetic valve loses power, and hydraulic oil in the energy accumulator can enter the hydraulic driving oil cylinder, so that the hydraulic driving oil cylinder drives the braking clamp to hold the rail tightly, and braking is realized.
Among these, it is understood that: the structures and implementation processes of the suspension control system 3 and the hydraulic brake system are not limited thereto, and the embodiment is only illustrated here.
The falling brake switch 1 may be electrically connected to a levitation control unit 31 in the levitation control system 3. The falling brake switch 1 is used for generating a falling brake instruction when receiving a control instruction input by a driver, and the falling brake instruction is used for triggering the suspension control system 3 to control the vehicle to fall. The falling brake instruction is used for triggering the suspension control unit 31 to generate a control instruction for controlling the falling, the suspension control unit 31 transmits the corresponding instruction to each suspension control module 33, and each suspension control module 33 controls the corresponding suspension to execute the falling action.
The levitation switch 32 and the landing brake switch 1 are electrically connected to the levitation control unit 31. The driver can control the falling through the suspension switch 32 and the falling brake switch 1 respectively.
The delay control module 2 is used for being electrically connected with the falling brake switch 1, and is used for being electrically connected with the emergency brake system 4, and is used for triggering the emergency brake system 4 to apply emergency brake to the vehicle after delaying preset time according to a falling brake instruction of the falling brake switch 1.
Wherein, the delay control module 2 can be electrically connected with the brake control unit 44 in the emergency brake system 4. The delay time may be determined according to actual conditions, and for example, the delay time may be 1.5 milliseconds, 1.6 milliseconds, and the like. So, at the in-process that falls the car, emergency braking can not apply immediately, and emergency braking is applied after the delay of predetermineeing the time again, for the certain buffering time of maglev train car that falls for can apply emergency braking after the execution falls the car, do benefit to and avoid the problem that emergency braking in-process suspension frame directly descends, reduce the impact to the vehicle, thereby do benefit to the security of guaranteeing the vehicle and passenger's travelling comfort.
In one possible implementation manner, as shown in fig. 2, the delay control module 2 includes: and the delay relay 21, wherein the delay relay 21 is provided with a control part and a delay contact 21a, the control part is connected with the falling brake switch 1 in series, and the delay contact 21a is used for disconnecting an emergency brake control loop in the emergency brake system 4 after delaying preset time.
In a specific implementation, the falling brake switch 1 may be at least one of the following: a button, a toggle switch and a touch screen. The implementation process of the present embodiment is not illustrated below by taking the falling brake switch 1 as a button, that is, taking the falling brake switch 1 as a falling brake button.
As shown in fig. 2 and 4, when the parking brake button is pressed to switch to the closed state, the closed parking brake button connects the control part of the time delay relay 21 to the power supply, so that the control part of the time delay relay 21 is powered. After the control part is electrified and delays for a preset time, the delay contact 21a is controlled to be opened, so that the emergency braking control loop is disconnected. After the emergency brake control circuit is disconnected, the control part of the emergency brake relay 43 is electrified, and the contact part 43a of the emergency brake relay is closed; in this case, the brake control unit 44 may be triggered to control the application of the mechanical brake, or the traction inverter 45 and the brake control unit 44 may be triggered to control the application of the dynamic brake and the mechanical brake, respectively.
The application of the mechanical brake, or the superposition of the mechanical brake and the dynamic brake, may be determined according to actual conditions, and the specific implementation process may be similar to that of the related art.
In addition, the contact part 43a of the emergency brake relay is also electrically connected to the network system 5, and the network system 5 is used for recording the state of the contact part 43a of the emergency brake relay, so as to facilitate subsequent inquiry. At this time, the contact part 43a of the emergency braking relay is connected in series with an ATP (Automatic Train Protection) cut-off switch 7, a device in the network system 5, and a power supply; the contact portion 43a of the emergency brake relay 43 is also connected in series with another device of the network system 5.
Optionally, a time delay contact 21a is used in series with the emergency brake button 41 in the emergency brake system 4. That is, the emergency brake control circuit can be disconnected when at least one of the delay contact 21a and the emergency brake button 41 receives a corresponding command.
Of course, in other examples, the delay control module 2 may also be implemented by a circuit structure having a delay function. The present embodiment and the following embodiments are not described by taking the delay relay 21 as an example.
Optionally, the emergency braking system 4 comprises two braking control branches arranged in parallel; the brake control branches each comprise an emergency brake button 41 and a time delay contact 21a connected in series. Therefore, double-loop control can be realized, and when one brake control branch fails and the function of delayed braking is difficult to realize, the other brake control branch can still be disconnected in a delayed manner, so that normal application of hydraulic braking can be ensured. Wherein, the brake control branch circuit, the cab occupation switch 6, the ATP brake switch 8, the power supply and the like form an emergency brake control loop.
Of course, in particular implementations, the braking control branch is not limited to two. For example, the number of brake control branches may be three or four, etc. In the present example, by setting the two brake control branches, it is possible to ensure that the hydraulic brake is normally applied, which is beneficial to reducing the cost.
In a specific working process, when the two brake control branches are normal, current passes through the two brake control branches; when the time delay contacts 21a in the two brake control branches are opened, the emergency brake control circuit is opened, and accordingly, the control part of the emergency brake relay 43 is powered and enables the brake control unit 44 to generate an emergency brake signal, which is used to trigger the execution of an emergency braking operation.
When one brake control branch circuit fails and cannot be electrified, current can still pass through the other normal brake control branch circuit; when the time delay contact 21a in the normal brake control branch is opened, the emergency brake control loop is opened, accordingly, the control part of the emergency brake relay 43 is powered and the brake control unit 44 is enabled to generate an emergency brake signal, which is used to trigger the execution of the emergency brake operation. And after the operation of the magnetic suspension train is finished, the brake control branch with the fault can be overhauled and maintained.
Optionally, the braking control device for the falling vehicle further includes a master control handle 42, the master control handle 42 has a plurality of working positions, one of the working positions is a release position, and the master control handle 42 controls the emergency braking system 4 to release when switching to the release position. Thus, when the main control handle 42 is in other working positions, the emergency brake cannot be relieved, so that the emergency brake cannot be relieved accidentally.
In one possible implementation manner, in addition, a network relay electrically connected with the network system 5 is further arranged in the emergency braking system 4, and a contact part 46a of the network relay is arranged in series in the brake control branch; the network relay is used to control the contact portion 46a of the network relay to open the emergency brake control loop in the emergency brake system 4 when receiving a high level signal of the network system 5.
In this example, once the network system 5 receives a signal of overspeed from the vehicle or a door opening during operation of the vehicle, the network system 5 sends a high signal to energize the control portion of the network relay, which controls the contact portion 46a of the network relay to open, so that the emergency brake control circuit is opened, and the vehicle is applied with emergency braking.
In one possible implementation manner, the falling brake switch 1 is further configured to be electrically connected to a network system 5, and the network system 5 is configured to record an operation state of the falling brake switch 1 so as to facilitate query during subsequent repair and maintenance.
In addition, in the related art, if the emergency brake button 41 fails, the suspension-down command of the train can be sent by the suspension switch 32, but the emergency brake of the train cannot be applied, so that the train can be caused to fall down emergently during the driving process but cannot stop, which has a great influence on the safety of the train and human body.
In this example, however, the application of the emergency brake may still be accomplished by the drop brake button upon failure of the emergency brake button 41. Accordingly, emergency braking may also be applied by the emergency brake button 41 in the event of a failure of the landing brake button. Therefore, when the magnetic suspension train meets an emergency and needs to be stopped suddenly, the emergency braking operation can be reliably realized, and the safety of vehicles and people is further improved.
Furthermore, it is understood that: regarding the levitation control system and the emergency braking system, the parts not described in this embodiment can be configured conventionally in the field.
The present embodiment also provides a magnetic levitation train comprising: a vehicle body and a falling brake control device; the falling brake control device is mounted to the vehicle body. As shown in fig. 2 and 4, two head cars are respectively shown on the left and right sides of the longitudinal center in the figure; the driver can operate the falling brake control system in any vehicle and realize falling and delay applying emergency brake.
