Description

Technical Field

[0001] The present application relates to the technical field of rail transit, and specifically, to an acquisition-driving integrated system and a signal acquisition-driving device that implement redundant configuration. Background Art

[0002] The acquisition of input signals is an important link in the field of rail transit. By acquiring and monitoring the input voltage fed back by external load devices, the state of external devices can be accurately judged. Digital quantity safety output is also a basic function of rail transit, and through double-break control, the safety control of external devices is realized.

[0003] Since the types of external load devices used in the railway signal field are diverse and the device voltage range is wide, at present, the acquisition system and the driving system in the railway signal system are separated separately to form an independent acquisition system sub-rack or driving system sub-rack, so as to realize the acquisition or control function of the external device state respectively. In practical applications, due to the differences in platform scales, the number of external devices at each station is different. Therefore, the acquisition sub-rack system or driving sub-rack system with fixed configuration ability lacks flexibility in application and there is serious resource waste. Moreover, there are many peripheral devices that need to collect states and control outputs at each station. Conventional interconnections require a large number of interconnection hard wires, making it difficult to control the project cost, and at the same time, there are safety risks brought by the interconnection.

[0041] Embodiment 1

[0042] In this application, through a safe and reliable direct plug-in connector, a compatible design is made between the signal acquisition unit board and the signal drive unit board, innovatively enabling the coexistence of the acquisition subsystem and the drive subsystem, and improving the flexibility of the integrated system application.

[0043] By adopting highly integrated signal acquisition unit boards and signal drive unit boards, the load-carrying capacity of the integrated system is improved, so that the redundant configuration of the acquisition subsystem and the redundant configuration of the drive subsystem can be completed within only the same subrack, facilitating the acquisition or drive control of more external devices.

[0044] As Figure 1 shown, in order to adapt to the various external load devices used in the railway signal field and the wide external voltage input, and to improve the flexibility of the application of the acquisition subsystem and the drive subsystem, an acquisition-drive integrated system with redundant configuration is innovatively designed. This integrated subsystem can make a compatible design between the conventional acquisition subrack system and the drive subrack system, and coexist the two subrack systems within the same subsystem, optimizing the railway signal design in terms of security, flexibility, availability, cost reduction, etc.

[0045] In the first aspect of this application, an acquisition-drive integrated system with redundant configuration is provided, including:

[0046] A communication control board for communicating with the upper-level ECU-MPU system; the communication control board is used to communicate with the upper-level ECU-MPU system and convert the network communication method of the ECU-MPU into CAN bus communication.

[0047] A signal acquisition unit board for collecting and monitoring the input voltage fed back by the external load device to accurately judge the state of the external load device; the signal acquisition unit board is used to realize the collection and monitoring of the input voltage fed back by the external load device to accurately judge the signal of the state of the external device.

[0048] A signal drive unit board for dual-break safety control and safety control of the external load device;

[0049] An acquisition and drive backplane for expanding the signal acquisition unit board into a redundant acquisition subsystem, expanding the signal drive unit board into a redundant drive subsystem, and simultaneously designing the redundant acquisition subsystem and the redundant drive subsystem to be compatible and coexist, and connecting to the external load device;

[0050] The communication control board, the signal acquisition unit board, and the signal drive unit board are all configured on the acquisition and drive backplane; moreover, the signal acquisition unit board and the signal drive unit board are respectively communicatively connected to the communication control board, and the communication control board is communicatively connected to the ECU-MPU system.

[0051] Specifically, both the signal acquisition unit board and the signal drive unit board adopt a secure two-out-of-two architecture, and securely and reliably perform information interaction with the communication control board that also adopts a two-out-of-two architecture.

[0052] The communication control board receives the IO command data packet from the control system ECU-MPU through the network, splits the data packet, and sends it to the signal acquisition unit board and the signal drive unit board through the CAN bus.

[0053] The signal acquisition unit board communicates with the communication control board, receives the CAN instruction, is used to collect the status of the external load device, and sends the securely collected device status to the communication control board through the CAN bus for uploading. Each single board has a rich, powerful and wide voltage range of acquisition interfaces, and each single board can independently collect the status of 24 external devices with an input voltage range of 0 to 60 VDC in a two-out-of-two manner at most.

[0054] The signal drive unit board communicates, receives the CAN instruction, is used to achieve secure drive control of the external load device, simultaneously feedbacks the control status, and sends the result to the communication control board through the CAN bus for uploading. Each single board also has a rich, powerful and wide voltage range of control interfaces, and each single board can independently control 10 external devices with an output voltage range of 0 to 60 VDC in a two-out-of-two manner at most.

[0055] The above redundant configuration structure specifically realizes the redundancy of the communication function through two communication control boards installed in slots 11 to 12 configured in this embodiment Figure 1 in the configured slots.

[0056] Next, the composition of the redundant acquisition system will be specifically described.

[0057] As an alternative embodiment of the present application, optionally, at least two of the signal acquisition unit boards are provided on the acquisition drive backplane, and two adjacent signal acquisition unit boards are configured as the redundant acquisition subsystem.

[0058] As an alternative embodiment of the present application, optionally, at least one redundant acquisition subsystem is configured on the acquisition drive backplane.

[0059] A total of 12 single boards can be embedded in the acquisition drive backplane. Taking two adjacent single boards as a group, six identical groups are formed.

[0060] If both of the adjacent ones are signal acquisition unit boards, then this group is configured as a redundant acquisition subsystem.

[0061] Therefore, at least one redundant acquisition subsystem is configured on the acquisition drive backplane, and six groups are preferably configured in this embodiment.

[0062] As an alternative embodiment of the present application, optionally, at least two of the signal drive unit boards are provided on the acquisition drive backplane, and two adjacent signal drive unit boards are configured as the redundant drive subsystem.

[0063] As an alternative embodiment of the present application, optionally, at least one redundant drive subsystem is configured on the acquisition drive backplane.

[0064] A total of 12 single boards can be embedded in the acquisition drive backplane. Taking two adjacent single boards as a group, six identical groups are formed.

[0065] If both of the adjacent ones are signal drive unit boards, then this group is configured as a redundant drive subsystem.

[0066] Therefore, at least one redundant drive subsystem is configured on the acquisition drive backplane, and six groups are preferably configured in this embodiment.

[0067] A redundant configuration of the acquisition subsystem or a redundant configuration of the drive subsystem is formed.

[0068] As Figure 1 shown, each acquisition drive backplane can be configured with a maximum of six acquisition subsystems or six drive subsystems or a convergence system of six acquisition subsystems and drive subsystems in a redundant manner. The acquisition subsystem and the drive subsystem are made to be compatible and coexist within one system and are directly connected to external load devices used in the railway signal field.

[0069] Both the signal acquisition unit board and the signal drive unit board have a relatively high degree of integration, which improves the load-carrying capacity of the integrated system. They have rich, powerful and wide-voltage-range acquisition and drive interfaces. Each board can independently acquire the status of 24 external devices with an input voltage range of 0 to 60 VDC, and each board can independently control 10 external devices with an output voltage range of 0 to 60 VDC in a double-break control mode.

[0070] The acquisition and drive integrated system forms an acquisition subsystem by combining two adjacent signal acquisition unit boards to complete redundant acquisition of the input voltage fed back by external load devices. The acquisition and drive integrated system forms a drive subsystem by combining two adjacent signal drive unit boards to achieve redundant and safe control of external devices. At the same time, the signal acquisition unit board and the signal drive unit board are designed to be compatible, innovatively enabling the coexistence of the acquisition subsystem and the drive subsystem, which improves the flexibility of the integrated system application. As a result, redundant configuration of the acquisition subsystem and redundant configuration of the drive subsystem can be completed within just the same subrack, facilitating the acquisition or drive control of more station devices.

[0071] In this application, the specific number of redundant acquisition subsystems and redundant drive subsystems can be determined according to the required number of interfaces, and this embodiment can be not limited.

[0072] As an optional implementation of this application, optionally, at least one of the redundant acquisition subsystems, at least one of the redundant drive subsystems, and at least one communication control board are configured on the acquisition and drive backplane.

[0073] According to the above redundant configuration method, in this embodiment, a convergence system of 6 acquisition subsystems and drive subsystems can also be configured. It enables the compatible coexistence of the acquisition subsystem and the drive subsystem within one system. As Figure 1 shown, the redundant acquisition subsystem, the redundant drive subsystem, and the communication control board are simultaneously configured on the acquisition and drive backplane. Only the number of installation slots for the communication control board needs to be configured and installed according to the principle of saving interfaces and slots.

[0074] By adopting a standardized pin layout design for connectors, the present invention enables two adjacent signal acquisition unit boards to form an acquisition subsystem to complete redundant acquisition of the input voltage fed back by external load devices. Two adjacent signal drive unit boards form a drive subsystem to achieve redundant and safe control of external devices.

[0075] The acquisition and drive integrated system designed by the present invention to achieve redundant configuration uses an innovatively designed acquisition and drive backplane to complete all the interconnection lines required for redundant configuration in the form of internal PCB traces, reducing external wiring, improving safety and reliability, and reducing costs.

[0076] Embodiment 2

[0077] Based on the implementation principle of Embodiment 1, this embodiment provides a mounting device.

[0078] The second aspect of this application provides a signal acquisition and drive device, including:

[0079] The acquisition and drive integration system that realizes redundant configuration described in the first aspect.

[0080] A 6U-sized rack is adopted to fixedly install the acquisition and drive integration system that realizes redundant configuration in the above Embodiment 1. In this embodiment, as the rack for fixedly installing the acquisition and drive integration system that realizes redundant configuration, its specific size, structure, and the design position of the slots, etc., are not limited in this embodiment, as long as it is designed according to the system configuration described in the above Embodiment 1.

[0081] As an optional implementation scheme of this application, optionally, it further includes:

[0082] A rack on which the acquisition and drive integration system that realizes redundant configuration is fixedly installed;

[0083] A number of slots are configured on the rack and correspond to the connectors on the acquisition and drive backplane in the acquisition and drive integration system that realizes redundant configuration;

[0084] The communication control board, signal acquisition unit board, and signal drive unit board of the acquisition and drive integration system that realizes redundant configuration are respectively fixedly connected to the corresponding connectors on the acquisition and drive backplane through the slots.

[0085] The 6U-sized rack adopts standard dimensions, and the rear part of the rack is used to fix the acquisition and drive backplane.

[0086] As Figure 1 shown, slots serving as plug-in interfaces are fitted and installed on the rack. In this embodiment, 12 slots (consisting of odd and even slots) are provided on one side of the rack for fixing the communication control board, signal acquisition unit board, and signal drive unit board, so that they are vertically inserted into the connectors on the acquisition and drive backplane to achieve connection.

[0087] Among them, the signal acquisition unit board can be placed in any slot from slot 01 to 12, the signal drive unit board can be placed in any slot from slot 01 to 12, and the communication control board is placed in two slots, slot 11 and slot 12.

[0088] The acquisition drive backplane is fixedly installed on the rack (or inside), and its connectors need to correspond to the slots on the rack for easy plugging according to the slots. The system uses an acquisition drive backplane with an innovative design, which completes all the interconnection wires required for redundant configuration in the form of internal PCB traces, reducing external wiring, improving the overall safety of the system, reducing costs, having a relatively high economic value, and greatly enhancing the reliability and usability of the acquisition drive integrated system.

[0089] Through this plugging method, the load-carrying capacity of the integrated system can be improved. It has rich, powerful and wide-voltage-range acquisition drive interfaces. Each board can independently acquire the status of 24 external devices with an input voltage range of 0 to 60 VDC, and each board can independently control 10 external devices with an output voltage range of 0 to 60 VDC in a double-break control manner.

[0090] Through the slots, the communication control board, signal acquisition unit board and signal drive unit board can be plugged into the corresponding connectors on the acquisition drive backplane.

[0091] As an optional implementation of this application, optionally, the several slots include:

[0092] The signal acquisition unit boards of two adjacent slots are configured on the rack and are connected to external load devices through a remote interface on one of the acquisition drive backplanes to implement a redundant-configured acquisition integrated system;

[0093] The signal drive unit boards of two adjacent slots are configured on the rack and are connected to external load devices through a remote interface on one of the acquisition drive backplanes to implement a redundant-configured drive integrated system.

[0095] Odd interfaces are configured on the acquisition drive backplane and are connected in parallel with the signal acquisition unit board and the signal drive unit board on the odd slots through an internal interface on one of the acquisition drive backplanes;

[0096] Even interfaces are configured on the acquisition drive backplane and are connected in parallel with the signal acquisition unit board and the signal drive unit board on the even slots through an internal interface on one of the acquisition drive backplanes.

[0097] Such as Figure 1As shown in the figure, in order to ensure the independence of the single boards in the odd slots and the single boards in the even slots of the system, in this embodiment, a number of slots are divided into odd slots (1, 3, 5, 7, 9, 11) and even slots (2, 4, 6, 8, 10, 12). By separating the odd interfaces and the even interfaces, the independence of the single boards in the odd slots and the single boards in the even slots of the system is ensured. At the same time, the odd interfaces and the even interfaces can be interconnected with another acquisition drive integrated system to achieve further expansion of the system.

[0098] The internal interface 01 of the acquisition drive backplane of this application is interconnected with the external output terminals of the single board in the odd slot, and the internal interface 02 is interconnected with the external output terminals of the single board in the even slot. Both are finally interconnected with the external load device through the remote interface.

[0099] The odd interface of the acquisition drive backplane provides functions such as independent power supply, CAN communication, and slot address recognition for the single board in the odd slot through the internal interface 03; similarly, the even interface provides functions such as independent power supply, CAN communication, and slot address recognition for the single board in the even slot through the internal interface 03. By separating the odd interface and the even interface, the independence of the single board in the odd slot and the single board in the even slot of the system is ensured. At the same time, the odd interface and the even interface can be interconnected with another acquisition drive integrated system to achieve further expansion of the system.

[0100] The above are only selected embodiments and are not used to limit this application. For those skilled in the art, this application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included within the protection scope of this application.
