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 obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
The core of the invention is to provide a redundant train passenger emergency braking control device and method, which are used for improving the reliability of emergency braking so as to ensure that the emergency braking request of passengers can be normally realized.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a block diagram of a redundant train passenger emergency brake control device according to an embodiment of the present invention. As shown in fig. 1, the apparatus includes a first emergency brake control apparatus 1 electrically connected to a TCMS3, and further includes: and the second emergency brake control device 2 is synchronously operated with the first emergency brake control device 1, the second emergency brake control device 2 comprises an emergency brake switch 20 arranged in a passenger compartment and an air path control device 21 connected with a train pipe, when the emergency brake switch 20 is triggered, the air path control device 21 controls the air pressure change of the train pipe, and the TCMS3 is also used for detecting the air pressure change of the train pipe and carrying out emergency brake operation processing according to the electric signal output by the first emergency brake control device 1 and the air pressure change of the train pipe.
In a specific implementation, each passenger compartment is provided with a train passenger emergency brake control device, and one passenger emergency brake control device or a plurality of passenger emergency brake control devices can be arranged. As a preferred embodiment, the passenger compartment is normally provided with a plurality of first emergency brake control devices 1 and a plurality of second emergency brake control devices 2. The first emergency brake control device 1 and the second emergency brake control device 2 are operated synchronously, the first emergency brake control device 1 is the same as the prior art, when an emergency brake switch of the first emergency brake control device is pressed, an electric signal can be sent to the TCMS3, the electric signal indicates that the emergency brake switch in the corresponding compartment is pressed, meanwhile, the emergency brake switch 20 in the second emergency brake control device 2 is also triggered, and when the emergency brake switch 20 is triggered, the air circuit control device 21 controls the air pressure of a train pipe to change, for example, the pressure of the train pipe can be reduced. Under the condition that the train is normally operated, the pressure of the train pipe is kept at a certain value, usually 500kPa or 600kPa, only then the train can normally operate, and once the air pressure of the train pipe is reduced to a preset value, the train cannot operate. The TCMS3 will detect the pressure change of the train pipe in real time, and once the pressure change of the train pipe reaches a preset value, it indicates that the second emergency brake control device 2 also generates an emergency brake signal. At this time, the TCMS3 detects two different emergency braking signals, one is the electric signal of the first emergency brake control device 1, and the other is the air pressure change of the train pipe generated by the second emergency brake control device 2, and then the TCMS3 performs the emergency braking operation processing according to the electric signal and the air pressure change of the train pipe.
It should be noted that the emergency braking operation processing in this embodiment does not necessarily mean that the TCMS3 necessarily controls the train emergency braking, but it is only said that the TCMS3 has confirmed that the emergency braking signal is currently generated, and whether the emergency braking is actually performed needs to be comprehensively determined in combination with other situations. In addition, if the TCMS3 needs emergency braking, the method is the same as the existing emergency braking method, and the description of this embodiment is omitted.
In a specific implementation, if both the first emergency brake control device 1 and the second emergency brake control device 2 can operate normally, the TCMS3 receives two emergency brake signals, but the first emergency brake control device 1 transmits an electric signal, which has low reliability and may cause the TCMS3 not to receive the electric signal, whereas in this embodiment, the second emergency brake control device 2 operates synchronously with the first emergency brake control device 1, so even if the TCMS3 cannot receive the electric signal, the pressure change of the train pipe can be detected, and therefore, the TCMS3 can still perform emergency brake operation processing. In other words, the TCMS3 may perform the emergency braking operation only based on the electric signal, may perform the emergency braking operation only based on the air pressure change of the train pipe, or may perform the emergency braking operation based on both the electric signal and the air pressure change of the train pipe.
In a preferred embodiment, the emergency brake switch 20 of the second emergency brake control device 2 is provided integrally with the emergency brake switch 20 of the first emergency brake control device 1. The occupied area of components can be reduced by adopting the integral arrangement, certainly, the components can be arranged in a split manner besides the integral arrangement, and if the components are arranged in a split manner, a linkage manner can be adopted, namely, one emergency brake switch 20 is triggered, and the other emergency brake switch 20 is also indirectly triggered.
In addition, the emergency brake switch 20 is embodied as a pull ring type or a push button type. The pull ring type or the push button type may be a touch type, and the present invention is not limited thereto.
The redundant emergency braking control device for train passengers provided by the embodiment comprises a first emergency braking control device and a second emergency braking control device, wherein the first emergency braking control device and the second emergency braking control device work synchronously, generate electric signals and control the air pressure change of a train pipe respectively, can detect the two signals simultaneously, and perform emergency braking operation processing according to the two signals. Therefore, the emergency braking control device is provided with two emergency braking control devices which are redundant mutually, and the problem of low reliability caused by a single device can be solved. And secondly, the air channel control device in the second emergency brake control device controls the air pressure change of the train pipe, belongs to mechanical pure air control, and has higher reliability than an electric control mode.
Fig. 2 is a schematic diagram of a redundant train passenger emergency brake control device according to an embodiment of the present invention. In fig. 2, the emergency brake switch 20 of the second emergency brake control device 2 is provided integrally with the emergency brake switch 20 of the first emergency brake control device 1. As shown in fig. 2, the air path control device 21 specifically includes a pilot control device (not shown in the figure) controlled by the emergency brake switch 20, a pilot control pipe 210 having an air inlet communicated with the train pipe and an air outlet at the other end, the air outlet of the pilot control pipe 210 is connected to the atmosphere, and the pilot control device controls the air outlet of the pilot control pipe 210 to open after detecting a trigger signal of the emergency brake switch 20, or close otherwise.
Because the air inlet of the pilot control pipe 210 is communicated with the train pipe, air in the train pipe can enter the pilot control pipe 210, and when the emergency brake switch 20 is not triggered, the air outlet of the pilot control pipe 210 is closed, namely the pilot control pipe 210 is sealed, so that stable air pressure can still be maintained in the train pipe; when the emergency brake switch 20 is triggered, the pilot control device controls the exhaust port of the pilot control pipe 210 to be opened, that is, the pilot control pipe 210 is communicated with the atmosphere at this time, and the air in the train pipe is released into the atmosphere, so that the air pressure in the train pipe is reduced, and the stable air pressure cannot be maintained, and at this time, the TCMS3 performs the emergency brake operation processing after detecting the air pressure change.
In this embodiment, the pilot control tube 210 with an exhaust port is connected to the train pipe, so that whether the exhaust port is opened or not is determined according to the state of the emergency brake switch 20, thereby realizing the change of the air pressure in the train pipe.
Fig. 3 is a block diagram of another redundant train passenger emergency brake control device according to an embodiment of the present invention. On the basis of the above embodiment, as a preferable implementation, the emergency brake disabling device 4 connected to the TCMS3 is further included, and is configured to control the air pressure of the train pipe to be maintained in a preset state and to disable the electric signal output by the first emergency brake control device 1 when the TCMS3 determines that the current operating environment prohibits the emergency brake operation processing.
Although the passenger emergency brake control device is used for emergency braking of passengers in case of emergency, the train is in different environments and may run on the line, if the train runs on the line, a certain position cannot be subjected to emergency braking, or if other trains follow the train, the emergency braking brings about a greater safety hazard. In the light of the above scenario, the emergency braking disabling device 4 is adopted in the present embodiment to disable emergency braking. Specifically, after receiving the electric signal and detecting the air pressure change, the TCMS3 determines whether the current operation line is listed in the emergency braking scheme by using a preset emergency braking prohibition scheme, and if so, controls the air pressure of the train pipe to be maintained in a preset state, that is, the air in the train pipe is not in a continuous emptying state, so that the train can normally run. In addition, since the TCMS3 also receives the electric signal, the electric signal needs to be ignored at this time, and the specific operation may be to set a priority level, and when the current operating environment prohibits the emergency braking operation process, the priority level for prohibiting the emergency braking is higher than the priority level of the electric signal, so that the TCMS3 may perform the operation for prohibiting the emergency braking first.
As a preferred embodiment, the TCMS3 is specifically configured to determine that the current operation environment prohibits the execution of the emergency braking operation process when it is determined that the emergency braking is prohibited on the current operation route or a train follows within a preset distance behind the current operation route.
It should be noted that the TCMS3 needs to determine that the current operation line prohibits emergency braking by means of the position location module, and determine whether a train is following within a preset distance behind by means of the train operation schedule and the dispatching center.
Fig. 4 is a schematic diagram of another redundant train passenger emergency brake control device provided by an embodiment of the present invention. As shown in fig. 4, the emergency brake disabling device 4 specifically includes a suppression solenoid valve 40 and an exhaust valve 41 provided between the pilot control pipe 210 and the train pipe;
the first port of the exhaust valve 41 communicates with the train pipe, the second port of the exhaust valve 41 is connected to the first port of the suppression solenoid valve 40, the second port of the suppression solenoid valve 40 is connected to the intake port of the pilot control pipe 210, and the control end of the suppression solenoid valve 40 is connected to the TCMS 3.
In the present embodiment, the exhaust valve 41 and the suppression solenoid valve 40 are added between the train pipe and the pilot control pipe 210, so that the air in the train pipe and the pilot control pipe 210 is divided into two sections, the section between the exhaust port of the pilot control pipe 210 and the exhaust valve 41 is referred to as the upstream of the pilot control pipe 210, the section between the exhaust valve 41 and the train pipe is referred to as the downstream of the pilot control pipe, and the on/off state between the upstream of the pilot control pipe and the downstream of the pilot control pipe is controlled by the suppression solenoid valve 40.
1) Can be emergently braked
When the TCMS3 determines that the emergency braking operation process can be performed in the current operating environment, the control solenoid valve 40 is de-energized, and the first port and the second port of the solenoid valve 40 are communicated, which is equivalent to the communication between the train pipe and the pilot control pipe 210, and when the exhaust port of the pilot control pipe 210 is opened, the air in the train pipe is exhausted to the atmosphere, so that normal emergency braking is realized.
2) Inhibiting emergency braking
When the TCMS3 determines that the current operating environment prohibits the execution of the emergency braking operation process, the control solenoid valve 40 is energized, the first port and the second port of the solenoid valve 40 are blocked, which means that communication between the upstream of the pilot control pipe 210 and the downstream of the pilot control pipe 210 is not possible, and even if the exhaust port of the pilot control pipe 210 is opened, only the air upstream of the pilot control pipe 210 is exhausted, and the air downstream of the pilot control pipe 210 is not exhausted, it is listed that the air in the pipe is equivalent to being maintained in a stable state, thereby disabling the current emergency braking.
It should be noted that in the specific implementation, the exhaust valve 41 with an exhaust port may also be used, but in most cases, for example, in the case of ineffective emergency braking, the exhaust port is closed in normal operation of the train, and only in the case of emergency braking, the exhaust port may be opened to rapidly release the air in the train pipe.
On the basis of the above-described embodiment, as a preferred embodiment, a reset device 5 for resetting the emergency brake switch 20 is further included.
It should be noted that the resetting device 5 is the same as the prior art, and the description of this embodiment is omitted. The reset device 5 is the only device that can reset the emergency brake switch 20, and passengers cannot realize the reset device by themselves, and the reset device needs a worker to realize the reset device through a specific key.
The above embodiments have been described in detail with respect to a redundant train passenger emergency braking control device, and the present invention also provides a control method applied to the device. Fig. 5 is a flowchart of a redundant train passenger emergency braking control method according to an embodiment of the present invention. As shown in fig. 5, the method includes:

S11: and carrying out emergency braking operation processing according to the electric signal output by the first emergency braking control device and the air pressure change of the train pipe.
