Background
With the continuous development of social economy, rail transit plays an increasingly important role in public transport systems in China. During the operation of the rail vehicle, the safety of the rail vehicle mainly depends on an Automatic Train Protection (ATP) subsystem in an Automatic Train Control (ATC) and manual observation of a Train driver. However, sometimes rail vehicles operate in a degraded mode with ATP removed, such as: when no signal is covered in a motor car in a section of a vehicle, a parking lot, a test line and other areas, or a fault circuit needs to be isolated and degraded to be operated to a down-line position, the protection function of the ATP is cut off due to manual operation of a driver, and in this case, the ATP cannot continuously ensure safe and stable operation of the rail vehicle.
Currently, various train protection systems for ATP failure mode have been developed to solve the above problems, such as: RFID (Radio Frequency Identification), RCAS (rail Collision avoidance System), ACDN (Anti Collision Device Network), etc., however, such train auxiliary protection systems all need to be equipped with a complete set of complete equipment in the rail vehicle, and also need to change and change the original design structure of the rail vehicle, thus greatly increasing the equipment installation cost and the maintenance difficulty of the rail vehicle. At present, no effective solution exists for the phenomenon.
Therefore, how to reduce the installation cost and the maintenance difficulty of the equipment of the railway vehicle is a technical problem to be solved urgently by the technical personnel in the field.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic view of a safety protection system of a rail vehicle according to an embodiment of the present invention, where the safety protection system of the rail vehicle includes:
the communication module (11) is arranged at the end position of the target railway vehicle running line and used for receiving UWB signals;
the vehicle-mounted host (12) is connected with the communication module (11), arranged in a driving platform of the target rail vehicle facing the communication module (11) and used for sending a target UWB signal to the communication module (11), calculating a target distance between the target rail vehicle and a terminal position and a target running speed of the target rail vehicle at the current moment according to a feedback signal returned by the communication module (11), and sending a target trigger instruction to the brake controller (13) when the target distance and the target running speed reach preset conditions;
and the brake controller (13) is connected with the vehicle-mounted host (12), arranged in the driving platform and used for sending a target brake instruction to a brake control system of the target railway vehicle when receiving the target trigger instruction so as to trigger the brake control system to perform emergency braking on the target railway vehicle.
In the embodiment, the safety protection system of the railway vehicle is provided, which can reduce the installation cost and the maintenance difficulty of the railway vehicle equipment. In the safety protection system, a communication module (11) for receiving UWB (Ultra Wide Band) signals is arranged at the end position of a target railway vehicle running line, and then a vehicle-mounted host (12) and a brake controller (13) are arranged in a driving platform of the target railway vehicle facing the communication module (11).
In the process of safely braking a target rail vehicle by a rail vehicle safety protection system, a vehicle-mounted host (12) firstly sends a target UWB signal to a communication module (11) arranged at the end position of a target rail vehicle running line, then calculates the target distance between the target rail vehicle and the end position and the target running speed of the target rail vehicle at the current moment according to a feedback signal returned by the communication module (11), and sends a target trigger instruction to a brake controller (13) when the calculated target distance and the target running speed reach preset conditions.
When the brake controller (13) receives a target trigger command sent by the vehicle-mounted host (12), the brake controller (13) sends a target brake command to a brake control system of the target railway vehicle so as to trigger the brake control system of the target railway vehicle to perform emergency braking on the target railway vehicle.
Compared with other wireless communication technologies, the UWB wireless communication technology has a unique frequency spectrum width, so that when the UWB signal is used to calculate the target distance between the target rail vehicle and the end point and the target running speed of the target rail vehicle at the current time, the influence of the frequency spectrum widths of other frequencies on the calculation accuracy can be avoided, and the accuracy and reliability of the target distance and the target running speed in the calculation process can be further improved. In addition, by using the UWB wireless communication technology, because the information is transmitted by using the extremely short pulse without the carrier, when the transmitting end transmits the target UWB signal, a power amplifier and a frequency mixer are not needed, and intermediate frequency processing is not needed at the receiving end, thereby greatly reducing the complexity of hardware realization and the design cost. In addition, because the power consumption required by the UWB wireless communication technology is very low, the stable and reliable operation of the rail vehicle safety protection system can be ensured.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating the in-vehicle host and the communication module in communication. Firstly, the vehicle-mounted host (12) sends a target UWB signal requesting for measuring the distance between the target railway vehicle and the end position to the communication module (11), and when the communication module (11) receives the target UWB signal sent by the vehicle-mounted host (12), a feedback signal corresponding to the target UWB signal is returned to the vehicle-mounted host (12); when the vehicle-mounted host (12) receives the feedback signal returned by the communication module (11), the feedback signal can be used to calculate the Time of flight (Time of light, Time of flight ranging method) of the target UWB signal between the communication module (11) and the vehicle-mounted host (12), so that the target distance between the target rail vehicle and the end point position and the target running speed of the target rail vehicle at the current moment can be calculated according to the Time of flight and the target UWB signal.
In practical application, the brake control system of the target railway vehicle adopts hard-wire control, and is a loop triggered by power failure, that is, if a high level disappears once any position in the brake control system of the target railway vehicle forms a broken circuit, the emergency brake of the target railway vehicle is triggered, and the target railway vehicle is caused to stop.
The open circuit state of a circuit breaker (EBTLCB) in the brake control system of the target railway vehicle is a sufficient condition for triggering emergency brake, wherein two ends of the circuit breaker (EBTLCB) are usually connected with a plug-in terminal strip, when the circuit breaker (EBTLCB) is short-circuited into an on-board device of the target railway vehicle, the normal work of the rest part of an emergency brake loop cannot be influenced, and the emergency brake triggered by other conditions can still be normally applied. If the vehicle-mounted host (11) of the target railway vehicle has a fault, the contact replacing the breaker is maintained in a normally open state, the target railway vehicle can automatically trigger emergency braking due to the disconnection of an emergency braking loop, and a motor car cannot be driven, so that the safe running state of the target railway vehicle is ensured.
In this embodiment, a circuit breaker (EBTLCB) in a target rail vehicle is selected as an emergency braking trigger point, then two interfaces TB04CREC/13 and TB04CREC/131 are reserved on the on-board host, and the interfaces TB04CREC/13 and TB04CREC/131 are connected with the circuit breaker, specifically please refer to fig. 3, and fig. 3 is a schematic diagram when the circuit breaker is connected with the interface in the on-board host.
After the connection is carried out, the vehicle-mounted host (12) can control the on-off of the emergency brake safety loop of the target railway vehicle by controlling the on-off of the interfaces TB04CREC/13 and TB04CREC/131, and directly control whether the emergency brake of the target railway vehicle is applied or not.
Referring to fig. 4, fig. 4 is a schematic diagram illustrating a connection between the on-board host and an internal circuit of the target rail vehicle. In actual operation, a logic device inside the on-board host (12) can be used instead of the circuit breaker (EBTLCB). Specifically, two interfaces may be reserved on the on-board host (12), which are named as X1A and X1B (or two connection points of the same interface are reserved on the on-board host), and then the interface XA and the interface XB are connected in series through a logic device inside the on-board host (12), so as to replace a circuit breaker to control the target rail vehicle.
Before the equipment of the vehicle-mounted host (12) is not accessed, the emergency braking safety loop of the target railway vehicle is shown as an upper half broken line block diagram, after the vehicle-mounted host (12) is accessed, the breaker (EBTLCB) is broken, a circuit diagram shown as a lower half broken line block diagram is connected, at the moment, a logic device K1 inside the vehicle-mounted host (12) replaces the original breaker (EBTLCB), and therefore the logic device K1 can act according to the logic shown in the table 1 and control the on-off condition between XA and XB.
TABLE 1 logic actions corresponding to Preset conditions
That is, when the on-board host (12) recognizes that the current 'speed-distance' parameter of the target railway vehicle meets the preset condition, the normally closed contacts 11 and 12 of the relay K1 can be tripped by controlling the power loss of the coil of the relay K1, so that the emergency braking safety loop of the target railway vehicle is disconnected, and at the moment, the target railway vehicle can immediately apply emergency braking and realize safe parking.
It should be noted that, in this embodiment, only two interfaces TB04CREC/13 and TB04CREC/131 on the target rail vehicle are taken as examples for specific description, in practical applications, the two interfaces may be replaced by other types of interfaces, and the preset conditions may also be adaptively modified according to different vehicle types in different rail vehicle projects, which is not described in detail herein.
In addition, in practical application, the target rail vehicle can run from the starting position to the end position, and can also return to the starting position again from the end position, therefore, in order to facilitate the convenience of the target railway vehicle in the actual operation process, the communication module (11) can be arranged at the initial position and the end position of the target railway vehicle running line, namely, a communication module A is arranged at the initial position of a target railway vehicle running line, a communication module B is arranged at the end position of the target railway vehicle running line, and then, a vehicle-mounted host (12) and a brake controller (13) are arranged in the driving platforms at the head end and the tail end of the target railway vehicle, namely, a vehicle-mounted host A and a brake controller A are arranged in a driving platform at the head end of the target railway vehicle, and a vehicle-mounted host B and a brake controller B are arranged in a driving platform at the tail end of the target railway vehicle. Referring specifically to fig. 5, fig. 5 is a block diagram of another safety protection system for a rail vehicle according to an embodiment of the present invention.
Obviously, in the safety protection system for the rail vehicle provided by the embodiment, only the communication module (11) is required to be arranged at the end point of the running line of the target rail vehicle, and the vehicle-mounted host (12) and the brake controller (13) are arranged in the driving platform of the target rail vehicle facing the communication module (11), so that the target rail vehicle can be safely and emergently braked without changing and changing the original design structure of the target rail vehicle, and therefore, the equipment installation cost and the maintenance difficulty of the rail vehicle can be greatly increased.
It can be seen that, in this embodiment, first, a communication module for receiving a UWB signal is disposed at an end position of a target rail vehicle travel route, then, a vehicle-mounted host is disposed in a driving platform of the target rail vehicle facing the communication module, and the vehicle-mounted host sends the target UWB signal to the communication module, so that the vehicle-mounted host can calculate a target distance between the target rail vehicle and the end position and a target travel speed of the target rail vehicle at the current time in real time according to a feedback signal returned by the communication module. When the target distance and the target running speed reach preset conditions, the vehicle-mounted host sends a target trigger instruction to a brake controller arranged in a target driving platform; when the brake controller receives a target trigger instruction sent by the vehicle-mounted host, the target brake instruction is sent to a brake control system of the target railway vehicle so as to trigger the brake control system of the target railway vehicle to perform emergency braking on the target railway vehicle. Obviously, in the railway vehicle safety protection system provided by this embodiment, only the communication module needs to be set at the end point of the target railway vehicle operation line, and the vehicle-mounted host and the brake controller need to be set in the cab of the target railway vehicle facing the communication module, and the original design structure of the target railway vehicle does not need to be changed and changed, so that the equipment installation cost and the maintenance difficulty of the railway vehicle safety protection system can be greatly reduced.
Based on the above embodiment, this embodiment further describes and optimizes the technical solution, and specifically, the safety protection system for a railway vehicle further includes:
and the power supply module is used for supplying power to the brake controller (13).
It can be understood that the brake controller (13) plays an extremely important role in the operation process of the target railway vehicle, so in the embodiment, in order to ensure the normal use of the brake controller (13), a power supply module for supplying power to the brake controller (13) is also arranged in the safety protection system of the railway vehicle, so that the power supply module can provide a stable power supply source for the brake controller (13). Specifically, the power supply module may be set as the power supply module of the AC 220V.
Therefore, the technical scheme provided by the embodiment can further improve the stability and reliability of the safety protection system of the railway vehicle.
As a preferred embodiment, the in-vehicle host (12) further includes:
and the display is used for displaying the target distance, the target running speed and power supply data of the power supply module to the brake controller (13).
In the running process of the target railway vehicle, the target distance between the target railway vehicle and the end point position, the target running speed of the target railway vehicle at the current moment and the power supply data of the power supply module to the brake controller (13) all influence the running state of the target railway vehicle in the running process, so in the embodiment, in order to enable a worker to more clearly and intuitively check the data, a display is arranged on the vehicle-mounted host (12), namely, the target distance between the target railway vehicle and the end point position in the running process, the target running speed at the current moment and the power supply data of the power supply module to the brake controller (13) are displayed by the display.
Therefore, through the technical scheme provided by the embodiment, the target distance between the target railway vehicle and the terminal position, the target running speed at the current moment and the power supply data of the power supply module can be displayed more clearly and intuitively.
As a preferred embodiment, the brake controller (13) further includes:
and the indicator light is used for displaying the power supply state of the power supply module.
It can be understood that the power supply module plays an important role in the safe and stable operation of the brake controller (13), so in order to further improve the safety performance of the brake controller (13) in the use process, an indicator lamp for displaying the power supply state of the power supply module is also arranged on the brake controller (13), and obviously, the power supply state of the power supply module can be displayed in real time by the indicator lamp in such a way.
