Compared with the conventional device in which each function module is provided with an independent power supply module, an independent processing module and an independent communication module, the technical scheme of the application realizes multiplexing of the power supply board card, the processing board card and the exchange communication board card, and reduces the rest unnecessary power supply board card 20, the processing board card 30 and the exchange communication board card 40, so that the management and control device can realize multiple functions and fully saves the occupied space of the device; on the other hand, the power supply board card, the processing board card and the exchange communication board card are shared, so that the utilization rate of the shared board card is improved, and the comprehensive cost of the equipment can be reduced.

In some embodiments, as shown in fig. 3, a power bus is disposed on the backplane 10, and the power board 20 is electrically connected to the processing board 30, the switch communication board 40, and the at least one function board 50 respectively through the power bus.

The power board 20 may provide power to other boards, such as the processing board 30, the switch communication board 40, and the functional boards 50, through a power bus disposed on the backplane 10. In some embodiments, the power supply voltage of each board is the same and is the voltage of the power bus, so that each board can share one or a group of power supply boards 20, which is convenient for designing and installing the circuit. The voltage of the power bus may be a 5V power supply voltage, a 12V power supply voltage, or a 24V power supply voltage, which is not specifically limited in the present application.

Alternatively, the power supply board 20 may be directly connected to the power supply bus, OR may be connected to the power supply bus via the OR-ing circuit 210. The OR-ing circuit 210 is generally used for a plurality of power supply circuits, can ensure mutual independence among a plurality of single power supplies, is internally provided with a diode, ensures unidirectional conduction of the circuit, and does not generate a current backflow phenomenon, so that the OR-ing circuit is connected to a power supply bus to realize functions of double current equalization, backflow prevention, fault isolation and the like.

In some embodiments, as shown in fig. 3, a communication bus is disposed on the backplane 10, and the switch communication board 40 is electrically connected to the processing board 30 and the at least one function board 50 through the communication bus.

The communication bus may be referred to herein as a high-speed communication bus for enabling high-speed transmission of data. For example, referring to fig. 5 in combination, the communication bus may be an ethernet bus, and the present application does not limit the type of the communication bus. The switching communication board 40 can provide data exchange for other boards through a communication bus, the switching core 410 is a core block of the switching communication board 40, has a data forwarding function, and can forward data transmitted by the board to other boards receiving data, and each board can realize data communication between boards through the data forwarding function of the switching communication board 40. For example, data communication between one processing board 30 and another processing board 30 may be implemented, data communication between one functional board 50 and another functional board 50 may be implemented, and data communication between the processing board 30 and the functional board 50 may be implemented.

In addition, the exchange communication board 40 may further be provided with an optical port 411 and an electrical port 413 capable of being connected to an external device, for implementing data communication with an external system, where the optical port 411 may be connected to an optical fiber device, the electrical port 413 may be connected to a wire device, and the number (denoted by N in fig. 5) of the optical port 411 and the electrical port 413 may be set autonomously according to a requirement, which is not limited in number in this application.

In some embodiments, as shown in fig. 3, a board management bus is disposed on the backplane 10, and the processing board 30 is electrically connected to the power board 20, the switch communication board 40, and the at least one function board 50 through the board management bus.

The board management bus is used for processing boards to manage all the functional boards, and functions of card insertion detection, board information identification, low-speed bus communication and the like are achieved. The card detection is used for detecting whether a card is inserted into the corresponding slot of the card, the card information identification is used for identifying which card is inserted, and the low-speed bus is used for accessing data of the low-speed card. Illustratively, an I2C bus can be adopted to realize card insertion detection and card information identification, and an RS485 bus can be adopted to access data of a low-speed card. The I2C bus is one of serial buses, and the RS485 bus is one of low-speed communication buses.

The processing board 30 may perform function management on other boards through a board management bus, where the processing board 30 may be configured to: sending an inquiry command carrying a target slot position identification through a board card management bus, wherein the target slot position identification is the identification of a target slot position in a plurality of slot positions; and if response information corresponding to the query command is received, determining the relevant information of the board inserted into the target slot position according to the board information contained in the response information.

For example, referring to fig. 6 and fig. 7 in combination, the backplane 10 is provided with a plurality of slot positions, and each slot position of each slot is configured with a set of slot ID circuits, and the signal identification of the slot ID can be implemented by a combination of a set of high and low level signals. For example, 1 corresponds to a high level, 0 corresponds to a low level, a binary slot ID number may be performed for each slot, the binary ID number corresponding to slot 1 may be 0001, the binary ID number corresponding to slot 2 may be 0010, and 0 and 1 herein may represent other meanings, which is not limited in this application. When the board card is inserted into the slot, the corresponding slot ID circuit can read the slot ID number of the slot, that is, the position information of the slot where the board card is located can be obtained. The target slot ID is a slot ID of a target slot among the multiple slots, and the slot ID may be used as a communication address of the board, and the processing board 30 may send a board inquiry command to a board corresponding to the slot ID through the board management bus, so as to obtain information of the board inserted into the target slot. If the board card of the target slot receives the query command sent by the processing board card 30 for the slot ID number, the board card may respond to the query command and feed back response information. The response information may include type information and function information of the target slot board, and the processing board 30 may determine what board is inserted into the target slot according to the response information. If no board is inserted into the target slot, the board query command cannot be received, and response information cannot be fed back to the processing board 30, so that the processing board 30 can judge whether the board is inserted into the target slot according to whether the response information is received.

In addition, if the volume of the communication data is small and the data information can be transmitted through the low-speed communication bus, the processing board 30 sends a board query command to the board of the target slot and receives feedback response information from the processing board, and the data information can be directly transmitted through the low-speed communication bus without passing through the exchange communication board 40. If the volume of the communication data is large and the low-speed communication bus cannot realize the transmission of the volume of data information, the processing board 30 and the target slot insertion board need to complete the communication via the exchange communication board 40. The processing board 30 sends a board inquiry command of the target slot to the exchange communication board 40, where the inquiry command includes a slot ID of the target slot and an instruction for inquiring board information inserted in the target slot. After the exchange communication board 40 receives the board query command, the exchange core 410 confirms the board object to be forwarded according to the slot ID of the target slot, and forwards the query command to the board of the target slot. When feeding back the response information, the board card of the target slot needs to send the response information to the exchange communication board card 40, where the response information includes the information of the board card inserted into the target slot, and also includes the slot ID of the response object. After the switching communication board 40 receives the response information, the switching core 410 forwards the response information to the processing board 30 according to the slot ID of the response object. If no board is inserted into the target slot, the exchange communication board 40 cannot find the forwarding object when confirming the board object to be forwarded, and the board query command is not forwarded. The processing board 30 sends a board inquiry command through the board management bus after the equipment is started, so that information inquiry is performed on the ID numbers of all the slots, and according to whether each slot feeds back response information and the board information in the response information, a board insertion detection function of a target slot can be realized, whether a board is inserted into a corresponding slot of the board is detected, and the information identification function of the processing board on other boards is realized, so as to identify which board is inserted into the slot.

The board management bus can adopt buses with different performances to implement corresponding transmission functions for transmission requirements of different data. For example, a serial bus (e.g., an I2C bus) may be used to implement the card insertion detection function and the card information identification function, where the I2C bus is composed of a serial data line and a serial clock line, and has a simple structure, and does not need a special interface circuit, and thus, the backplane wiring may be simplified and the wiring cost may be reduced. The low-speed communication bus (such as an RS485 bus) can be used for accessing data of the low-speed board card, some function board cards do not need to use a high-speed communication bus such as an Ethernet, when the quantity of transmitted data is small, the RS485 low-speed communication bus can be used for data communication, the RS485 low-speed communication bus is low in cost, and the wiring cost of the backboard can be reduced by combining the RS485 bus with other types of buses.

In some embodiments, as shown in fig. 7, the plurality of slots includes: the system comprises a power supply slot position 60, an exchange communication slot position 70 and at least three general slot positions 80, wherein optionally, the number of the power supply slot positions 60 is at least two; the interfaces of the power supply slot 60 comprise a power supply bus interface and a board management bus interface, and the power supply board 20 is electrically connected with the backboard 10 through the power supply slot 60; the interfaces of the exchange communication slot 70 include a power bus interface, a board management bus interface and a plurality of communication bus interfaces, and the exchange communication board 40 is electrically connected with the backplane 10 through the exchange communication slot 70; the interfaces of the universal slot 80 include a power bus interface, a board management bus interface, and a communication bus interface, and the processing board 30 or the functional board 50 is electrically connected to the backplane 10 through the universal slot 80.

The exchange communication board 40 inserted in the universal slot 80 cannot provide a data exchange function, and can be used as a communication interface to access data information of an external device, for example, the optical port 411 and the electrical port 413 can be connected to the external device to implement data communication with an external system. The universal slot 80 can be inserted into any type of processing board card 30, switching communication board card 40 and functional board card 50 at will, and each universal slot 80 does not limit the type of the inserted board card to be the processing board card 30, the switching communication board card 40 or the functional board card 50.

And the first processing board card and the second processing board card are configured and synchronized at regular time. If the processing board 30 in the active mode is the first processing board, when the device works normally, the first processing board completes all processing operations, and after a set time, the first processing board needs to perform synchronous transmission backup of working information with the second processing board, including sending information of a board query command, receiving response information of feedback, board information in the response information, and the like. Meanwhile, the first processing board card and the second processing board card need to perform heartbeat package interaction at regular time so as to determine whether the two parties are in a normal working state. If the first processing board does not receive a response reply from the second processing board within a specified time after sending the heartbeat packet, the second processing board may be in an offline state or a failure state. If the second processing board card does not receive the heartbeat packet sent by the first processing board card after the specified time, it may be determined that the first processing board card is in an abnormal working state, and at this time, the second processing board card may be changed to be in the active mode to temporarily perform the processing work of the device. The second processing board needs to send a query command to the first processing board at a fixed time in the subsequent operation to confirm the working state of the first processing board, and if the second processing board receives response information from the first processing board in the working process, the second processing board indicates that the first processing board recovers the normal working state, the first processing board is in the active mode again, and the second processing board is in the standby mode. Through the backup of the data information by the two processing board cards 30, the data loss or damage caused by the fault problem of the processing board cards 30 can be avoided, and the arrangement of one standby processing board card 30 can ensure that the standby board card can still ensure the normal operation of the equipment even if the board card in the main mode is in an abnormal state.
