Embodiment Construction

[0031] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] figure 1 Shown is a switching device, in order to improve reliability, the switching device includes a main control board and two Ethernet switching boards with the same function. Among them, the main control board judges the running status of the two Ethernet switching boards by receiving the status report Ethernet packets of the two Ethernet switching boards. When the main Ethernet switching The network package controls the active / standby switchover of the Ethernet switch board.

[0033] refer to figure 2 , an FPGA-based Ethernet switch board status monitoring transceiver, including a Gigabit Ethernet module 100, an Ethernet switch module 110, a CPU module 120, an FPGA module 130, a temperature measurement module 140 and a power supply module 150. figure 2 It is an electric principle logic block diagram of an embodiment...

Abstract

The invention discloses an Ethernet exchange board card state monitoring transmitting and receiving device based on an FPGA, and belongs to the technical field of communication networks. In the device, a gigabit Ethernet module is used for realizing level conversion, coding and decoding and framing and de-framing functions; an Ethernet switching module is used for realizing an Ethernet packet switching processing function; a CPU module is used for realizing control and protocol processing and initialization and configuration query functions of each functional module; an FPGA module is used formonitoring and collecting various state information in real time and reporting and receiving a main / standby switching instruction; the temperature measuring module is used for measuring the surrounding temperature of the main chip; the power module is used for power supply and power conversion. According to the invention, the independent state monitoring Ethernet interface is adopted to transmitinformation, the normal function of the switching equipment is not influenced, the FPGA is adopted to automatically monitor the state of the board card, parallel processing and real-time monitoring can be realized, real-time reporting of state information and rapid switching of the main state and the standby state can be realized, and the reliability of the switching equipment is enhanced.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to an FPGA-based Ethernet switching board status monitoring transceiver. Background technique [0002] In recent years, with the rapid development and widespread popularization of network technology, various industries have put forward higher and higher requirements for the stability and reliability of network equipment. In some key high-performance and complex applications, it is necessary to ensure long-term stable and error-free work, and any tiny fault will cause immeasurable losses. [0003] In actual systems, redundancy means are generally used to realize system fault tolerance and improve system reliability. A redundant system usually adds one or more systems or modules that are identical to the original system or some important modules in the original system on the basis of the original system. When one set of modules or systems fail to operate normally, oth...
