In order to better understand the technical solution and technical effect of the present application, an integrated access device in the embodiment of the present application is first described.
In an embodiment of the present application, the integrated access device includes a management module, an access module slot, and an access module in the access module slot. The access module is used for providing an access interface, and is connected with other devices needing to be accessed through the access module, the devices needing to be accessed can be a telephone, a computer, a switch, a gateway and the like, and one or more services of data, voice, multimedia and the like can be accessed to a user through the integrated access device. The management module is a module for managing the access module, and generally, the management module performs data communication with the corresponding access module according to a received control instruction.
In specific application, the management module can be arranged in a slot position of the management module or directly arranged in a circuit board, the management module is connected with each access module slot position through a preset electric connecting line in the circuit board, the connection mode comprises communication connection of a serial port bus and an Ethernet bus, and after the access module is accessed to the access module slot position, a data port of the access module is connected with a port corresponding to the access module slot position, so that the access module can communicate with the management module through the serial port bus or the Ethernet bus.
It should be noted that, whether the access module can communicate with the management module through the serial port bus or the ethernet bus, because whether the access module itself supports the serial port bus connection or the ethernet bus connection, that is, when the access module supports the serial port bus connection, the data port in the interface module related to the serial port bus connection is connected with the port corresponding to the slot serial port bus connection of the access module, so that the access module can communicate with the management module through the serial port bus; similarly, when the access module supports ethernet bus connection, the data port of the interface module associated with the ethernet bus connection is connected to the port corresponding to the slot ethernet bus connection of the access module, so that the access module can communicate with the management module via the ethernet bus.
Based on the above integrated access device, the embodiments of the present application provide a flowchart of a data transmission method of an integrated access device. Referring to fig. 1, the data transmission method may include the following steps S101 to S102:
s101: and judging whether the access module supports Ethernet bus connection, if so, communicating the management module and the access module through the Ethernet bus.
In practical applications, compared with a mode of communication through a serial port bus, a mode of communication through an ethernet bus has an advantage of faster data transmission rate, and therefore a mode of communication through the ethernet bus should be preferentially selected. In addition, the access device in the access module slot may support the communication mode corresponding to the bus only when it needs to be connected to the bus in the access module slot, otherwise, the access device does not support the communication mode corresponding to the bus. For example: the access device in the slot of the access module can support the communication mode through the Ethernet bus only when being connected with the Ethernet bus on the slot of the access module, otherwise, the access device does not support the communication mode through the Ethernet bus. It can be seen that the communication modes supported by each access module are not necessarily identical, for example: the access module A only supports a mode of communication through an Ethernet bus; the access module C may support two modes of communication via a serial bus and an ethernet bus.
In this embodiment, it is first determined whether the access module supports ethernet bus connection, and if the access module supports ethernet bus connection, that is, if the access module supports the mode of communication through the ethernet bus, the management module may communicate with the access module through the ethernet bus.
S102: if not, whether the access module supports the connection of the serial port bus is judged, and if so, the management module and the access module communicate through the serial port bus.
In this embodiment, it is determined that the access module does not support ethernet bus connection, that is, the access module does not support a communication mode through the ethernet bus; it may be determined whether the access module supports serial bus connection to determine whether it supports a mode of communicating through the serial bus, and if so, the management module may communicate with the access module through the serial bus.
In an implementation manner of this embodiment, if the access module does not support serial bus connection, an error notification message is returned.
In this embodiment, if it is determined by the determination that the access module does not support both ethernet bus connection and serial bus connection, it may be determined that the access module does not support both the communication mode through the ethernet bus and the communication mode through the serial bus. At this point, an error prompt message may be returned to the management module.
In an implementation manner of this embodiment, a connection manner supported by the access module may be obtained in advance, specifically, the access module in the access module slot is marked with the supported connection manner in advance, and the supported connection manner includes ethernet bus connection and serial bus connection; then the process of the first step is carried out,
judging whether the access module supports the Ethernet bus connection or not, including: judging whether the access module supports Ethernet bus connection or not through the supported connection mode marked in advance by the access module;
judge whether access module supports serial port bus connection, include: and judging whether the access module supports serial port bus connection or not through the supported connection mode marked in advance by the access module.
In this embodiment, the connection mode supported by the access module in each access module slot may be predetermined and marked. The connection mode supported by the access module may include ethernet bus connection and serial bus connection. For example: if the access module A in the slot position of the access module is only determined to support the Ethernet bus connection in advance, marking the mode that the access module A supports the Ethernet bus connection; if the access module B in the slot position of the access module is only determined to support serial bus connection in advance, marking the mode that the access module B supports the serial bus connection; if it is determined in advance that the access module C in the slot position of the access module supports both ethernet bus connection and serial bus connection, the tag access module C supports both the ethernet bus connection and the serial bus connection. If it is predetermined that the access module D in the slot of the access module does not support the ethernet bus connection nor the serial bus connection, the tag access module D does not support the ethernet bus connection nor the serial bus connection. In a specific application, for example, the connection modes supported by the access module may be marked by text, table, database, assignment, and the like.
In an implementation manner of this embodiment, referring to fig. 3, this figure is a flowchart of a method for pre-marking a connection manner supported by an access module according to an embodiment of the present application, and may include the following steps S201 to S202:
s201: performing a first poll, the first poll comprising: the management module sends inquiry information to the access module in the slot position of the access module through the serial bus, and if the management module receives a response, the management module marks the access module as supporting the serial bus connection.
In this embodiment, first, it is marked whether the access module in each access module slot supports serial bus connection in a first polling manner. The method specifically comprises the following steps: the management module sends inquiry information to the access module in each access module slot position through the serial port bus, and if the management module receives the response of the access module, the management module marks the access module to support the serial port bus connection; and if the management module does not receive the response of the access module, marking the access module that the serial port bus connection is not supported. Therefore, the access module in each access module slot can be marked whether the access module supports serial bus connection.
S202: performing a second poll, the second poll comprising: the management module sends inquiry information to the access module in the slot position of the access module through the Ethernet bus, and if a response is received, the access module is marked as supporting the Ethernet bus connection.
In this embodiment, after the first polling manner is performed to mark whether the access module in each access module slot supports serial bus connection, the second polling manner may be performed to mark whether the access module in each access module slot supports ethernet bus connection. The method specifically comprises the following steps: the management module sends inquiry information to the access module in each access module slot position through the Ethernet bus, and if the management module receives the response of the access module, the management module marks the access module to support the Ethernet bus connection; if the management module does not receive the response of the access module, the management module marks that the access module does not support the Ethernet bus connection. The access module in each access module slot can thus be marked whether it supports ethernet bus connections. It should be noted that, in this embodiment, the order of the first polling and the second polling is not particularly limited, and step S201 may be performed first, and then step S202 may be performed; step S202 may be performed first, and then step S201 may be performed.
In a specific application, a polling thread may be added to the polling portion of the management module to query the connection mode supported by the access module in each access module slot.
Therefore, after marking the connection modes supported by the access module in each access module slot, the method for determining whether the access module supports ethernet bus connection may include: and judging whether the access module supports Ethernet bus connection or not through the supported connection mode marked in advance by the access module. For example: according to the connection mode of the access module A for supporting the Ethernet bus connection, the access module A can be judged to support the Ethernet bus connection; according to the connection mode of the access module B for supporting serial bus connection, the access module B can be judged not to support Ethernet bus connection. Similarly, it can be determined that the access module C supports ethernet bus connection and the access module D does not support ethernet bus connection.
Similarly, the method for judging whether the access module supports serial bus connection may include: and judging whether the access module supports serial bus connection or not through the supported connection mode marked by the access module in advance. For example: according to the connection mode of the access module A for supporting the Ethernet bus connection, the access module A can be judged not to support the serial bus connection; and according to the connection mode of the access module B for supporting the serial port bus connection, judging that the access module B supports the serial port bus connection. Similarly, it can be determined that the access module C supports serial bus connection and the access module D does not support serial bus connection.
To sum up, in the data transmission method of the integrated access device provided in the embodiment of the present application, the management module in the integrated access device is connected to the slot of the access module through the serial bus and the ethernet bus, and then the data transmission method of the integrated access device includes: judging whether the access module supports Ethernet bus connection, if so, communicating the management module and the access module through the Ethernet bus; if not, whether the access module supports the connection of the serial port bus is judged, and if so, the management module and the access module communicate through the serial port bus. By the method, the management module can be ensured to communicate with the access module through the Ethernet bus with higher transmission rate, so that the data transmission efficiency is improved; in addition, the management module and the access module can communicate in two communication modes of an Ethernet bus and a serial bus, so that the possibility of communication abnormity between the management module and other access modules caused by abnormal communication between the management module and one access module is reduced, and the reliability of data transmission is further ensured.
