Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
FIG. 1 is a schematic diagram of an interface between a door control system and a signaling system in the prior art, and can be referred to in FIG. 1, in which the same door is controlled by only one set of interlocking devices, the on-board ATP of the train sends an open/close command to the interlocking devices, and after the interlocking devices receive the open/close command, the command is forwarded to the door control system; meanwhile, the platform door control system feeds the real-time state information of the platform door back to the interlocking equipment, and the interlocking equipment forwards the state information to the vehicle-mounted ATP. Fig. 2 is a schematic diagram of an interface circuit structure between a platform door system and a signal system in the prior art, and as shown in fig. 1 and 2, a relay interface circuit is adopted between a platform door control system and the signal system for information transmission, so that all trains can monitor the platform door through the same set of interlocked interface circuits. In fig. 2, the left side relay is used for the platform door to send the door status to the signal system, wherein MGJ indicates that the door is closed and the locking relay MPLJ indicates that the door bypasses the relay, and this part of the circuit is the existing circuit structure, which is not specifically described in the present invention.
Along with the large modification of a part of the track traffic line signal system which is opened at an early stage, in order to ensure that the normal operation requirement of the existing line is not interrupted, when the part of the line is modified and implemented, the requirement that a plurality of different types of train vehicle-mounted equipment control the same platform door can exist. In the current scheme, for trains which cannot be interconnected and communicated with the existing ground interlocking equipment, the platform door cannot be monitored. Because the monitoring of the vehicle-mounted ATP to the platform door needs to be transferred through the interlocking equipment, the situation that the mixed operation of different types of vehicle-mounted trains (such as a train A and a train B) cannot be met by arranging one set of interlocking equipment in the prior art. Therefore, the invention realizes the receiving of the ATP command and the forwarding of the related information of the corresponding train (such as the train B) by adding a set of interlocking equipment, and can meet the requirement that the trains of different types can switch and control the same platform door through the corresponding interlocking equipment.
In the invention, the existing interlocking equipment is used as first interlocking equipment, and the train to which the vehicle-mounted ATP communicated with the platform door control system through the first interlocking equipment belongs is a first type train; and taking the newly added interlocking equipment as second interlocking equipment (for example, other types of trains introduced by line modification, and configuring corresponding interlocking equipment for the newly introduced types of trains), wherein the train to which the vehicular ATP communicated with the platform door control system through the second interlocking equipment belongs is the second type of train.
Fig. 3 is a schematic structural diagram of a platform door switching control circuit provided by the present invention, and as shown in fig. 3, the present invention provides a platform door switching control circuit, which includes a door opening relay module 301 and a door closing relay module 302, wherein:
The door opening relay module 301 is electrically connected to the first interlocking device and the second interlocking device, and is configured to generate a corresponding door opening signal according to a door opening instruction sent by the first type train or the second type train, and send the door opening signal to the platform door control system, so that the platform door control system controls the platform door to open according to the door opening signal.
The door closing relay module 302 is electrically connected to the first interlocking device and the second interlocking device, and is configured to generate a corresponding door closing signal according to a door closing instruction sent by the first type train and/or the second type train, and send the door closing signal to the platform door control system, so that the platform door control system controls the platform door to be closed according to the door closing signal.
Fig. 4 is a schematic diagram of a platform door monitored by different interlocking devices through different types of vehicular ATP provided by the invention, as shown in fig. 4, by arranging two sets of interlocking devices, namely an interlocking a and an interlocking B, which are respectively and electrically connected with a door opening relay module 301 (meanwhile, the interlocking a and the interlocking B are also respectively and electrically connected with a door closing relay module 302), the vehicular ATP of the train a monitors a platform door control system through the interlocking a, and the vehicular ATP of the train B monitors the platform door control system through the interlocking B, thereby realizing command receiving and relevant information forwarding between the vehicular ATP of different types of trains and the corresponding interlocking devices. In the present invention, the type of the train is not particularly limited, and the first type of train may be a newly introduced train, and the second type of train may be a train that communicates with the existing interlocking device.
Specifically, the door opening relay module comprises a first door opening relay and a second door opening relay; the first door opening relay is driven according to a door opening instruction sent by the first interlocking device, and the second door opening relay is driven according to a door opening instruction sent by the second interlocking device.
The door closing relay module comprises a first door closing relay and a second door closing relay, wherein the first door closing relay is driven according to a door closing instruction sent by the first interlocking device, and the second door closing relay is driven according to a door closing instruction sent by the second interlocking device.
In the invention, in order to ensure the safety monitoring of the platform door, the control command interface of the signal system and the platform door control system needs to ensure uniqueness, namely, a scene that a plurality of interlocking devices are not allowed to send door opening commands/door closing commands to the same platform door at the same time. Further, taking two interlocking devices and the same platform door interface as an example for explanation, fig. 5 is one of interface circuit diagrams between a platform door control system and a signal system provided by the present invention, as shown in fig. 5, assuming that KMJ-a and GMJ-a are a door opening relay and a door closing relay corresponding to a current first set of interlocking devices, and configuring a door opening relay KMJ-B and a door closing relay GMJ-B corresponding to a second set of interlocking devices according to a newly introduced train type. In the invention, the door opening and closing commands of the two sets of interlocking equipment and the platform door adopt pulse level signals (high level is an effective signal), and as the high level effective signal of the door opening and closing is only existed in the period of train station entering and station stopping, the condition that two trains simultaneously send the door opening and closing commands to the same platform door at the same moment is ensured not to exist. Therefore, the invention can adopt a mode of connecting the contacts of the two sets of interlocking separately driven door opening relays (KMJ)/door closing relays (GMJ) in parallel to send door opening/closing commands to the platform door, namely when the train A enters the station, the KMJ-A is driven by the interlocking equipment A so that the door opening command of the interlocking equipment A is effectively commanded, and when the train B enters the station, the door opening command of the interlocking equipment B is effectively commanded by the interlocking equipment B, and the door opening command of the interlocking equipment B is specifically commanded by referring to FIG. 5.
In the present invention, when the door opening and closing command of the two interlocking devices and the platform door adopts a continuous level signal (high level is an active signal). For the door opening command, because the condition that two trains simultaneously send the door opening command to the same platform door does not exist at the same moment, the door opening command can be sent to the platform door in a mode that the interlocking A and the interlocking B drive the contacts of the corresponding door opening relays (KMJ) to be connected in parallel; for the door closing command, normally, after the train B starts from the platform, the interlocking B is a continuous level signal interface with the platform door, and the interlocking B always sends the door closing command to the platform door until the next train which controls the platform door through the interlocking B sends the door opening command; however, during this period, if the train a enters the station to stop and issues a door opening command, the door control system will receive the door opening command from the interlock a, and at this time, the door opening command of the interlock a and the door closing command of the interlock B are both in an effective state, so that the door control system determines that the door is in an abnormal state, and does not act on the door, which will affect the normal operation and reduce the availability of the station area, and fig. 6 is a timing diagram of the present invention when there is an abnormal state in the input/output between the door control system and the signal system, specifically, refer to fig. 6. Therefore, when the two interlocking devices and the door opening and closing command of the platform door adopt continuous level signals (high level is an effective signal), the parallel door closing relay in the double-set interlocking scene needs to be optimized to avoid the abnormal state.
In the present invention, when the door closing command is a continuous level signal, the door closing relays (i.e., GMJ-a and GMJ-B) corresponding to the interlocks a and B are connected in series to send the door closing command to the platform door based on the door closing relay module 302. FIG. 7 is a schematic diagram of an interface between a control system and a signaling system of a platform door according to the second embodiment of the present invention, referring to FIG. 7, after a train A enters a stop and issues a door opening command, an interlocking A control GMJ-A drops (i.e. GMJ-A is in an off state), at this time, the control system of the platform door will only receive the door opening command sent by the interlocking A to be in an active state, and the remaining commands are in an inactive state, i.e. the door closing command of the interlocking B will not cause an abnormal state, and the control system of the platform door will normally open the platform door; when the stop of the train A is finished, a door closing command sent by the vehicle-mounted ATP is a continuous level signal, the interlocking A drive GMJ-A is sucked up (namely GMJ-A is in a closed state) and the interlocking B drive GMJ-B is sucked up (namely GMJ-B is in a closed state), so that a platform door closing circuit is jointly conducted, and the platform door is controlled to normally close the platform door. Fig. 8 is a timing diagram of the normal status of input/output between the platform door control system and the signaling system according to the present invention, and specifically, refer to fig. 8.
In this embodiment, two circuit structures are provided for the door closing relay module 302, and when the door closing command is a continuous level signal, a structure in which relays are connected in series is adopted, and when the door closing command is a pulse level signal, a structure in which relays are connected in parallel is adopted.
The platform door switching control circuit provided by the invention realizes that different types of trains control the same platform door through the double-set interlocking equipment, solves the problem of interface control between the platform door and the signal system in the compatible operation scene of a plurality of different systems in the process of modifying and upgrading the signal system, avoids the platform door switching control in a manual or other non-automatic mode, and improves the safety of the platform door area.
Fig. 9 is a schematic flow chart of a method for controlling a platform door according to the present invention, and as shown in fig. 9, the method for controlling a platform door according to the present invention includes:
step 901, generating a corresponding door opening signal based on a door opening instruction sent by the first interlocking device or the second interlocking device;
step 902, sending the door opening signal to a platform door control system to control the opening of the platform door through the platform door control system.
In the invention, two sets of interlocking equipment are arranged to realize the control of the same platform door for different types of trains, wherein the first interlocking equipment and the second interlocking equipment are respectively connected with the corresponding door opening relay in a parallel mode. The door opening command (door opening command) of the two sets of interlocking equipment and the platform door adopts pulse level signals or continuous level signals (high level is an effective signal), and as the door opening high level effective signal exists only in the period of train entering and stopping, the condition that two trains simultaneously send door opening and closing commands to the same platform door at the same moment is required to be ensured not to exist. Therefore, the invention can adopt a mode of connecting the contacts of the two sets of interlocking separately driven door opening relays (KMJ) in parallel to send a door opening command to the platform door, for example, when a train A enters the station, the door opening relay KMJ-A corresponding to the interlocking equipment A is driven by the interlocking equipment A, so that the door opening command of the interlocking equipment A is received by the platform door system as a valid command, and when a train B enters the station, the door opening command of the interlocking equipment B is received by the platform door system as a valid command by the interlocking equipment B.
Step 903, generating a corresponding door closing signal based on a door closing instruction sent by the first interlocking device and/or the second interlocking device;
step 904, sending the door closing signal to a platform door control system to control the closing of the platform door by the platform door control system.
In the present invention, when the door closing command (door closing command) is a continuous level signal, the door control command is continuously transmitted during the process because the train leaves the platform and the train enters the platform before entering the platform. Therefore, in the time period of sending the instruction, the door closing relays (namely GMJ-A and GMJ-B) corresponding to the interlocking A and the interlocking B send a door closing command to the platform door in a contact series connection mode, after the train A enters the station to stop and sends out the door opening command, the interlocking A controls the KMJ-A to be in a suction (closed) state, the GMJ-A falls (namely GMJ-A is in an open state), at the moment, the platform door control system only receives the platform door opening command sent by the interlocking A to be in an effective state, and other commands are in an ineffective state, so that the platform door control system normally opens the platform door; when the stop of the train A is finished and a door closing command is sent, the interlocking A controls the KMJ-A to be in a falling (off) state, the driving GMJ-A is in a closed state, the interlocking B drives GMJ-B to be in a closed state, the interlocking A and the interlocking B jointly conduct a door closing circuit, and the platform door controls the platform door to be normally closed. When the command of closing the door is a pulse level signal, the train only sends a high level of closing the door during stop, and at this time, the relays are connected in parallel.
The platform door control method provided by the invention realizes that different types of trains control the same platform door through the double-set interlocking equipment, solves the problem of interface control of the platform door and the signal system under the compatible operation scene of a plurality of different systems in the process of modifying and upgrading the signal system, avoids the switching control of the platform door by manual or other non-automatic methods, and improves the safety of the platform door area.
On the basis of the embodiment, if the door closing command is a continuous level signal, the door closing relay correspondingly driven by the first interlocking device and the second interlocking device is connected in series;
If the door closing command is a pulse level signal, the door closing relay correspondingly driven by the first interlocking device and the second interlocking device is connected in parallel;
