Description
Technical Field
The invention relates to the technical field of control, in particular to a control device and a control method for emergency braking and a train.
Background
When the train enters and exits the station, passengers select to get on or off the train according to destinations. When a train driver controls a vehicle door to be closed and controls a vehicle to drive away, if a passenger meets an emergency and requests to get off the vehicle, the prior art mainly determines whether to stop the vehicle or not through subjective judgment of the driver. However, in the subjective judgment process, drivers often cannot accurately judge whether the vehicle has completely driven off the platform. For example, assuming that the length of a certain train is 180 meters, when the train is started and the distance between the head of the train and the nearest edge of the platform is less than 160 meters, if a passenger meets an emergency and requests to get off, the train can still stop running theoretically because part of the carriages of the train do not drive off the platform, and the doors are opened for the passenger to get off. However, the driver cannot accurately know the driving distance of the train by subjective judgment in the cab, and cannot determine whether the train completely drives away from the platform.
In summary, in the prior art, in the case that passengers require emergency braking, drivers determine whether parking is easy to cause adverse consequences through subjective judgment. On the one hand, drivers are conservative in subjective judgment, passengers are not allowed to get off even if the train is not completely at a platform, and riding experience of the passengers is seriously influenced. On the other hand, the driver is too bold when subjective judgment, and the personal safety of passengers is damaged.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. 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.
Fig. 1 is a schematic structural diagram of a control device for emergency braking according to an embodiment of the present invention, and as shown in fig. 1, the control device for emergency braking according to the embodiment of the present invention includes: the emergency braking control system comprises a signal receiving module 101, a position judging module 102, an emergency braking control signal generating module 103 and an emergency braking realizing module 104; the signal receiving module 101 is connected to the position determining module 102 and the emergency braking control signal generating module 103, respectively, the position determining module 102 is further connected to the emergency braking control signal generating module 103, and the emergency braking control signal generating module 103 is further connected to the emergency braking implementing module 104.
The following further describes each module in the control device.
The signal receiving module 101 includes an emergency braking trigger signal receiving unit and a position signal receiving unit. Wherein, the emergency braking trigger signal receiving unit is connected with an external emergency braking trigger device. The emergency brake triggering device is arranged in a train carriage, when a passenger triggers the emergency brake triggering device, the emergency brake triggering device can send an emergency brake triggering signal to the outside, and the emergency brake triggering signal receiving unit receives the emergency brake triggering signal. After receiving the emergency braking trigger signal, the emergency braking trigger signal receiving unit transmits the emergency braking trigger signal to the emergency braking control signal generating module 103.
The position signal receiving unit is used for receiving a position signal of the train at a first moment, and obtaining the position coordinate of the train at the first moment from information contained in the position signal. Wherein the first moment is the moment when the emergency braking triggering device is triggered.
The position signal receiving unit has multiple implementation modes, such as a GPS signal receiving device, a Beidou signal receiving device and the like. In the embodiment of the invention, the GPS signal receiving device can be adopted for implementation.
As is known to those skilled in the art, trains have a certain length. In the embodiment of the invention, for convenience of comparison in the subsequent steps, the position coordinate of a certain part on the train at the first moment is taken as the position coordinate of the train at the first moment, for example, the position coordinate of a GPS signal receiving device installed at the head of the train at the first moment is taken as the position coordinate of the train at the first moment.
The position signal receiving unit transmits the position coordinates of the train at the first time to the position judging module 102.
The position determining module 102 receives the position coordinate of the train at the first time from the position signal receiving unit in the signal receiving module 101, determines whether the train completely leaves the platform at the first time based on the position coordinate of the train at the first time and the position coordinate of the platform side, and transmits the determination result to the emergency braking control signal generating module 103.
As is known to those skilled in the art, a docking station has a certain length, and the distance from one edge end of the docking station to the other edge end is typically several kilometers. In the embodiment of the present invention, for the convenience of comparison, the position coordinates of one edge end of the platform are used as the position coordinates of the platform side. The platform has two edge ends, and the position coordinate of which edge end of the platform is specifically selected as the position coordinate of the platform side, so that the uplink and downlink signals of a line need to be combined. The running direction of the train can be known through the uplink and downlink signals of the line, and the position coordinate of the edge end of the platform where the train finally runs away is used as the position coordinate of the platform side according to the running direction of the train. Since the position coordinates of the edge of the station are fixed, they can be pre-stored in the position determination module 102. And when the comparison and judgment are carried out, the specific platform edge end coordinates are called by combining the uplink and downlink signals of the line.
After the position coordinates of the train at the first time and the position coordinates of the station side are obtained, a position determination signal indicating whether the train has completely left the station is generated based on the two position coordinates. In the description of the background art, it has been mentioned that, because the train has a certain length, even if the train head has moved away from the platform, the train can theoretically stop running as long as some cars have not moved away from the platform, and the doors are opened for passengers to get off (i.e., to respond to the emergency braking request of the passengers). Therefore, when generating the position determination signal, the first distance value needs to be used in addition to the position coordinates of the train at the first time and the position coordinates of the station side. Specifically, the method comprises the following steps:
if the position coordinate of the train at the first moment does not exceed the position coordinate of the station side along the running direction of the train, or the position coordinate of the train at the first moment exceeds the position coordinate of the station side, but the distance between the position coordinate of the train and the station side is within a first distance value, the train does not completely leave the station at the first moment;
if, in the direction of travel of the train, the position coordinate of the train at the first time exceeds the position coordinate of the station side and the distance to the position coordinate of the station side exceeds a first distance value, the train is completely separated from the station at the first time.
The size of the first distance value may be determined according to the actual condition of the train, considering that the train lengths of different consists are different. If the train length is 120 meters, then the magnitude of the first distance value may be set to 100 meters, and if the train length is 180 meters, then the magnitude of the first distance value may be set to 160 meters.
After obtaining the determination result of whether the train has completely driven off the platform, the position determination module 102 sends a position determination signal describing the determination result to the emergency braking control signal generation module 103. For example, a high level indicates that the train has not completely left the platform, and a low level indicates that the train has completely left the platform. Of course, in other embodiments of the present invention, other forms of position determination signals may be used to describe the determination result.
The emergency braking control signal generation module 103 determines whether to generate an emergency braking control signal according to the position determination signal and the emergency braking trigger signal received in real time.
When an emergency braking trigger signal exists and the position judging signal indicates that the train does not completely leave the platform at the first moment, generating an emergency braking control signal; and when the emergency braking trigger signal exists and the position judging signal indicates that the train completely leaves the platform at the first moment, the emergency braking control signal is not generated. The emergency brake control signal may be implemented in a variety of ways, such as being represented by a high signal or a low signal.
The emergency braking implementation module 104 receives the emergency braking control signal generated by the emergency braking control signal generation module 103, and implements emergency braking according to the emergency braking control signal. In one embodiment of the present invention, the emergency brake implementation module 104 may be implemented using a relay, wherein the connection and disconnection of the circuit in which the relay coil is located is controlled by the emergency brake control signal, and the contact (e.g., normally closed contact) of the relay is disposed in the existing train emergency brake loop. The emergency braking control signal controls the connection or disconnection of a circuit where the relay coil is located, and the connection or disconnection of the relay contact is influenced by the power-on or power-off of the relay coil, so that the existing train emergency braking loop is influenced. In another embodiment of the present invention, the emergency brake implementation module 104 may be implemented using a communication interface that transmits emergency brake control signals to the existing train emergency brake loop, which is in turn affected by the emergency brake control signals.
The control device for emergency braking provided by the embodiment of the invention can automatically realize the comparison between the position coordinate of the train at the moment when the emergency braking trigger device is triggered and the position coordinate of the platform side when the passenger triggers the emergency braking, and determine whether to carry out the emergency braking on the train according to the comparison result, thereby avoiding the error caused by purely depending on the manual judgment of a train driver and being beneficial to ensuring the safety of the passenger.
Based on any one of the embodiments, in the embodiment of the invention, the device further comprises a passenger emergency bypass, wherein the passenger emergency bypass is used for shielding an emergency braking triggering signal generated by triggering the emergency braking triggering device by a passenger.
After the passenger triggers the emergency brake triggering device, even if the train has not completely driven off the platform, the operation of the train is still not suitable to be stopped and the doors of the train are opened under certain conditions. For example, a fire occurs near a train and the train needs to be driven away from the site quickly. Therefore, in the embodiment of the invention, the device also comprises a passenger emergency bypass, and train staff (such as a train driver) activates the passenger emergency bypass through a control switch in the passenger emergency bypass so as to shield an emergency braking trigger signal. Namely: when the passenger emergency bypass is enabled, the emergency brake control signal generation module 103 cannot generate the emergency brake control signal even if there is an emergency brake trigger signal and the position determination signal indicates that the train has not completely left the platform at the first time.
According to the control device for emergency braking provided by the embodiment of the invention, the passenger emergency bypass is arranged, so that the train can not be braked emergently even if the passenger triggers the emergency braking triggering device and the train does not completely leave the platform, and the safety of the train and the passenger is ensured.
