As shown in fig. 1, fig. 1 is a schematic structural diagram of a multi-group platform door control system according to an embodiment of the present invention, which includes a central control panel 1 and a plurality of intelligent DCU modules 2, wherein the central control panel 1 includes a safety driving module 3 and a plurality of intelligent interface modules 4.
The input end of the intelligent interface module 4 is used for being connected with the platform door control equipment, receiving a multi-group control signal sent by the platform door control equipment, and generating a corresponding multi-group control initial instruction according to the multi-group control signal; the first output end of the intelligent interface module 4 is connected with the input end of the safety driving module 3, and is used for sending a multi-group control initial instruction to the safety driving module 3.
In this embodiment, the central control panel 1 includes a plurality of safety driving modules 3, wherein an input end of each intelligent interface module 4 is used for being connected with a platform door control device and receiving a multi-group control signal sent by the platform door control device. Wherein different multi-consist signals are used to control the actuation of platform doors corresponding to different consist trains. For example, assume that a consist of 8 consists, 1 consists corresponding to 2 train doors, i.e., where the multi-consist signal is used to control the platform door motion corresponding to 16 train doors of the train; similarly, when the consist of a train is 6 consists, then the multi-consist signal is used to control the platform door motion corresponding to the 12 train doors of the train.
After receiving the multi-group control signal sent by the platform door control device, the intelligent interface module 4 needs to further convert the multi-group control signal into a multi-group control initial instruction which can be identified by the platform door system, so as to realize conversion between an external signal and an internal signal. Then, since the first output end of the intelligent interface module 4 is connected with the input end of the safety driving module 3, the intelligent interface module 4 further sends the multi-group control initial instruction to the safety driving module 3 for processing after generating the multi-group control initial instruction.
The first output end of the safety driving module 3 is connected with the input ends of the intelligent DCU modules 2, and is used for carrying out signal conditioning on the multi-grouping control initial instruction, generating the multi-grouping control instruction and sending the multi-grouping control instruction to the intelligent DCU modules 2.
In this embodiment, the first output end of the safety driving module 3 is connected to the input ends of the plurality of intelligent DCU modules 2, and after receiving the multi-group control initial command, the safety driving module 3 further performs signal conditioning on the multi-group control initial command, for example, performs operations such as amplifying the multi-group control initial command, so as to obtain the multi-group control command. And then the safety driving module 3 sends the multi-group control instruction to the intelligent DCU module 2 through the first output end of the safety driving module so that the intelligent DCU module 2 controls the platform door.
On the basis of the above embodiment, the safety driving module 3 and the intelligent interface module 4 are connected through a hard wire, and the safety driving module 3 is connected with the intelligent DCU module 2 through a hard wire. Specifically, the first output end of the intelligent interface module 4 is connected with the input end of the safety driving module 3 through a hard wire, and the first output end of the safety driving module 3 is connected with the input ends of the intelligent DCU modules 2 through hard wires.
The output end of each intelligent DCU module 2 is connected with the control end of one platform door, and the intelligent DCU module 2 is used for controlling the corresponding platform door to execute corresponding actions when the corresponding platform door is determined to need to be controlled according to the multi-group control instruction.
Each intelligent DCU module 2, after receiving the multi-group control command outputted by the safety driving module 3, further determines whether to control the platform door controlled by itself according to the multi-group control command. If so, the corresponding platform door is controlled to execute corresponding actions according to the multi-group control instruction, for example, the platform door is controlled to execute door opening actions or door closing actions. In one embodiment, the multi-group control instruction includes the number information of the platform door to be controlled, the intelligent DCU module 2 also stores the number information of the platform door connected with the intelligent DCU module 2, and the intelligent DCU module 2 matches the number information stored by the intelligent DCU module with the number information in the multi-group control instruction, if the number information is matched with the number information, the platform door connected with the intelligent DCU module can be controlled.
In the above-mentioned embodiment of the present invention, when the platform door is required to be opened or closed in response to control of the multi-group vehicle, the intelligent interface module in the central control panel receives the multi-group control signal sent by the platform door control device, converts the multi-group control signal into the multi-group control initial command, and then transmits the multi-group control initial command to the safety driving module, and the safety driving module conditions the multi-group control initial command to generate the multi-group control command, and sends the multi-group control command to the intelligent DCU module, so that the intelligent DCU module controls the corresponding platform door to act according to the multi-group control command. The embodiment of the invention can be adapted to trains with different marshalling to control the platform door, has strong applicability and flexible operation, and solves the technical problem that the platform door system in the prior art cannot be adapted to the operation requirements of the multi-marshalling trains.
In one embodiment, as shown in fig. 2, fig. 2 is a schematic structural diagram of another multi-group platform door control system provided in an embodiment of the present invention, and in fig. 2, a plurality of intelligent interface modules 4 includes a first intelligent interface module 41, a second intelligent interface module 42, and a third intelligent interface module 43, and a platform door control device includes an integrated monitoring device, an in-situ control panel, and an integrated backup panel.
The integrated monitoring system is also called an integrated monitoring system, and is used for collecting state information of each device on the rail transit line, monitoring each device according to the state information, and simultaneously, the integrated monitoring system can also respond to input of a user, issue multi-group control signals and issue the multi-group control signals to the intelligent interface module 4. An in-situ control panel is a device by which a train operator interacts with a platform door system for enabling operation of the platform door by the train operator in an abnormal condition, such as a signaling system failure, or in an emergency condition. The comprehensive backup disc is used for carrying out emergency management on the station when a station operator on duty fails in a station equipment server or a man-machine interface; or directly operating buttons, key switches and the like on the comprehensive backup disc in emergency, and performing operation in a running mode and remote single-action operation of certain equipment in a manual intervention mode. In this embodiment, the integrated monitoring system, the on-site control panel and the integrated backup panel can all control the platform door by issuing a multi-group control signal to the intelligent interface module 4.
The input end of the first intelligent interface module 41 is used for being connected with the comprehensive monitoring equipment and receiving a multi-group control signal sent by the comprehensive monitoring equipment; and generating a corresponding multi-group control initial instruction according to the multi-group control signal.
In fig. 2, an input end of the first intelligent interface module 41 is configured to be connected to the integrated monitoring device, and is configured to receive a multi-group control signal sent by the integrated monitoring device, and then the first intelligent interface module 41 starts a corresponding group logic to convert the multi-group control signal into a multi-group control initial instruction, and then sends the multi-group control initial instruction to the safety driving module 3, so that after the safety driving module 3 conditions the group control initial instruction, the multi-group control instruction is sent to the intelligent DCU module 2, thereby implementing control of the platform door.
The input of the second intelligent interface module 42 is configured to connect to the local control panel and is configured to receive the multi-group control signal sent by the local control panel.
The input end of the second intelligent interface module 42 is connected to the local control panel, and when the integrated monitoring system fails and the local control panel is required to perform the station door, the operator can operate the local control panel to send a multi-group control signal to the second intelligent interface module 42, and after receiving the multi-group control signal sent by the local control panel, the second intelligent interface module 42 converts the multi-group control signal into a multi-group control initial command and sends the multi-group control initial command to the safety driving module 3, where the specific process is the same as that of the first intelligent interface module 41, and details are not repeated in this embodiment.
The input end of the third intelligent interface module 43 is used for being connected with the integrated backup disc and receiving the multi-group control signal sent by the integrated backup disc.
The input end of the third intelligent interface module 43 is connected to the comprehensive backup disc, and when an emergency fire accident occurs and the comprehensive backup disc is required to control the platform door, the third intelligent interface module 43 is configured to receive the multi-group control signal sent by the comprehensive backup disc, convert the multi-group control signal into a multi-group control initial command, and send the multi-group control command to the safety driving module 3, where the specific process is the same as that of the first intelligent interface module 41, and details are not repeated in this embodiment.
In the embodiment of the invention, three intelligent interface modules 4 are arranged in the central control panel 1, and the three intelligent interface modules 4 are respectively connected with the comprehensive monitoring equipment, the on-site control panel and the comprehensive backup panel, and the three intelligent interface modules 4 can respectively receive the multi-group control signals sent by the comprehensive monitoring equipment, the on-site control panel and the comprehensive backup panel, so that the control of the platform door is realized. So that the multi-group platform door control system can be adapted to different platform door control devices, and the applicability and flexibility of the multi-group platform door control system are improved.
On the basis of the above embodiment, the priority port of the first intelligent interface module 41, the priority port of the second intelligent interface module 42, and the priority port of the third intelligent interface module 43 are connected to each other, and the priorities of the third intelligent interface module 43, the second intelligent interface module 42, and the first intelligent interface module 41 are sequentially lowered.
In one embodiment, as shown in fig. 3, priority ports are disposed on the first intelligent interface module 41, the second intelligent interface module 42, and the third intelligent interface module 43, where the priority ports are used for receiving and sending priority signals, and the priority ports of the first intelligent interface module 41, the priority ports of the second intelligent interface module 42, and the priority ports of the third intelligent interface module 43 are connected with each other. In addition, in this embodiment, in order to avoid the collision caused by the simultaneous control of the platform doors by different platform door control systems, the priorities of the third intelligent interface module 43, the second intelligent interface module 42 and the first intelligent interface module 41 are sequentially reduced, wherein the priority is the priority of each intelligent interface module 4 for controlling the platform door, that is, in this embodiment, the priority of the integrated backup disc for controlling the platform door is the highest, the priority of the integrated monitoring system is the lowest.
When any one intelligent interface module 4 receives the multi-grouping control signal and determines that the intelligent interface module is not in a disabled state, a priority signal is generated, and the priority signal is sent to a priority port of the intelligent interface module 4 with a priority lower than that of the intelligent interface module 4 through the priority port, wherein the priority signal is used for indicating the intelligent interface module 4 to enter the disabled state, and the intelligent interface module 4 prohibits sending a multi-grouping control initial instruction to the safety driving module 3 in the disabled state.
In this embodiment, when any one of the intelligent interface modules 4 receives the multi-group control signal sent by the corresponding platform door control device, it is first determined whether the intelligent interface module 4 is in a disabled state, where the intelligent interface module 4 enters the disabled state when the priority port of the intelligent interface module 4 receives the priority signal, and in the disabled state, the intelligent interface module 4 prohibits sending the multi-group control initial command to the security driving module 3. After determining that the intelligent interface module 4 is not in the disabled state, the intelligent interface module 4 can generate a multi-group control initial instruction according to the multi-group control signal and send the multi-group control initial instruction to the safety driving module 3. Meanwhile, the intelligent interface module 4 generates a priority signal and sends the priority signal to all the intelligent interface modules 4 with lower priority than the intelligent interface module 4 through the priority port, so that the intelligent interface modules 4 with lower priority are forbidden to control the platform door. For example, when the third intelligent interface module 43 receives the multi-group control signal, it generates a multi-group control initial command according to the multi-group control signal, and at the same time, the third intelligent interface module 43 generates a priority signal and sends the priority signal to the second intelligent interface module 42 and the first intelligent interface module 41 through the priority port, so that when the integrated backup disc controls the platform door, the in-situ control disc and the integrated monitoring system are prohibited from controlling the platform door. In addition, it can be understood that, in the process of controlling the platform door by the on-site control panel or the integrated monitoring system, if the integrated backup panel controls the platform door, the control right of the platform door will be returned to the integrated backup panel at this time, and the on-site control panel or the integrated monitoring system cannot continuously control the platform door.
In the embodiment of the invention, the priority mechanism is set for the intelligent interface module, and when the intelligent interface module with higher priority controls the platform door, the intelligent interface module with lower priority is forbidden to control the platform door, so that the conflict generated when different intelligent interface modules control the platform door is avoided, and the normal operation of a platform door system is ensured.
Based on the above embodiment, the safety driving module 3 is specifically configured to amplify and isolate the multi-group control initial command, generate the multi-group control command, and send the multi-group control command to the intelligent DCU module 2.
In one embodiment, when the safety driving module 3 conditions the multi-group control initial command, the amplifying circuit is used to amplify the multi-group control initial command first, wherein the amplification is because the magnitude of the multi-group control initial command output by the intelligent interface module 4 is smaller, and the safety driving module 3 needs to drive the plurality of intelligent DCU modules 2, so that the multi-group control initial command needs to be amplified. After amplifying the multi-group control initial instruction, the amplified multi-group control initial instruction needs to be isolated, so as to generate the multi-group control instruction. The purpose of isolating the intelligent DCU module 2 from the multi-consist station door control system is to avoid the influence of the multi-consist station door control system on the intelligent DCU module 2. In one embodiment, an isolation circuit formed by combining a plurality of safety relays may be disposed in the safety driving module 3, and the amplified multi-group control initial command is isolated by using the plurality of safety relay combinations, so as to generate the multi-group control command. After generating the multi-group control command, the safety driving module 3 may send the multi-group control command to the intelligent DCU module 2.
On the basis of the above embodiment, each intelligent DCU module 2 includes a platform door control sub-module 21 and an instruction transmission sub-module 22.
The input end of the platform door control sub-module 21 is connected with the first output end of the safety driving module 3, and is used for receiving the multi-group control instruction sent by the safety driving module 3, and generating a platform door control instruction when the corresponding platform door is determined to be controlled according to the multi-group control instruction; the output end of the platform door control sub-module 21 is connected with the input end of the command transmission sub-module 22, and is used for sending the platform door control command to the command transmission sub-module 22, wherein the multi-group control command comprises the information of the platform door needing to be controlled.
In one embodiment, as shown in fig. 4, each intelligent DCU module 2 includes a platform gate control sub-module 21 and an instruction transmission sub-module 22. The input end of the platform door control sub-module 21 is connected to the first output end of the safety driving module 3, and is configured to receive the multi-group control instruction sent by the safety driving module 3. After receiving the multi-group control command sent by the safety driving module 3, the platform door control sub-module 21 determines whether to control the platform door connected with the intelligent DCU module 2 according to the information of the platform door to be controlled included in the multi-group control command. In one embodiment, the information of the doors to be controlled included in the multi-group control command is the number information of the doors, and each door control sub-module 21 also stores the number of the door connected to the intelligent DCU module 2. The platform door control sub-module 21 matches the stored platform door number with the platform door number included in the multi-group control command, and if the matching is good, it indicates that the corresponding platform door needs to be controlled, otherwise, the corresponding platform door does not need to be controlled.
The output end of the platform door control sub-module 21 is connected with the input end of the instruction transmission sub-module 22, and after determining that the platform door corresponding to the platform door needs to be controlled, the platform door control sub-module 21 further generates a platform door control instruction and transmits the platform door control instruction to the instruction transmission sub-module 22.
The output end of the command transmission sub-module 22 is connected to the control end of the platform door, and is used for controlling the platform door according to the platform door control command so as to enable the platform door to execute corresponding actions.
After receiving the platform door control command sent by the platform door control sub-module 21, the command transmission sub-module 22 controls the platform door through the control end of the platform door so that the platform door performs a corresponding door opening or closing action.
On the basis of the above embodiment, the central control panel 1 further comprises a data monitoring module 5.
The first input end of the data monitoring module 5 is connected with the second output ends of the plurality of intelligent interface modules 4 and is used for collecting first state data of the plurality of intelligent interface modules 4; the second input end of the data monitoring module 5 is connected with the second output end of the safety driving module 3, and is used for collecting second state data of the safety driving module 3.
In one embodiment, as shown in fig. 5, the central control panel 1 further includes a data monitoring module 5, where a first input end of the data monitoring module 5 is connected to a second output end of the plurality of intelligent interface modules 4, and is configured to collect first status data of the plurality of intelligent interface modules 4, and monitor an operation status of each intelligent interface module 4 according to the first status data. In addition, a second input end of the data monitoring module 5 is connected with a second output end of the safety driving module 3, and is used for collecting second state data of the safety driving module 3, and monitoring the safety driving module 3 according to the second state data. In an embodiment, the data monitoring module 5 is further connected to a cloud server, and when the data monitoring module 5 determines that the state of the intelligent interface module 4 or the safety driving module 3 is abnormal according to the first state data of the intelligent interface module 4 or the second state data of the safety driving module 3, the data monitoring module 5 is further configured to send abnormal information to the server, and the server notifies the user terminal according to the abnormal information, so that the user can overhaul the abnormal intelligent interface module 4 or the abnormal safety driving module 3 in time, and normal operation of the multi-grouping platform door control system is ensured. In addition, in the present embodiment, the data monitoring module 5 is connected to the intelligent interface module 4 and the security driving module 3 through hard wires.
In another embodiment, the data monitoring module 5, the intelligent interface module 4, the safety driving module 3, the platform gate control sub-module 21 and the command transmission sub-module 22 are all of a two-by-two redundant microprocessor architecture, and the safety driving module 3 is provided with a redundant isolation circuit.
