Problems solved by technology

[0006] For the clamping abnormality that occurs on the bus, the first two solutions currently given can only solve soft faults. If a physical failure of a node device occurs, the faulty node cannot be isolated and the blocked bus cannot be restored; the third method can Realize the isolation of faulty communication nodes, but all nodes need to be isolated, and the location of faulty nodes cannot be given

Embodiment Construction

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0032] figure 1A schematic structural diagram of an isolating device 10 for a bus working node of the present invention is given. As shown in the figure, the isolating device 10 is set in a working node 20 connected to the bus and includes an isolating unit 12 and a control unit 14 . The isolation unit 12 is connected between the bus 18 and the working nodes 20 , and is used for communicating or isolating the bus 18 and the working nodes 20 . That is, the bus signal transmitted from the bus 18 to the working node 20 will be transmitted ...

Abstract

The invention discloses a bus and working node isolation device. The isolation device is arranged in a working node of a bus, and comprises an isolation unit and a control unit, wherein the isolation unit is connected between the bus and the working node and used for connecting or isolating the bus and the working node; and the control unit detects the working state of a bus signal output to the working node through the isolation unit, and controls the isolation unit to connect or isolate the working node and the bus according to the detected working state. The isolation device can effectively isolate a fault node connected on the bus.

Description

technical field [0001] The invention relates to a bus clamp fault solution, in particular to a bus clamp fault recovery system and method. Background technique [0002] There are multiple working nodes connected to the communication bus. Therefore, in practical applications, an abnormality of one node will cause the entire bus to be clamped (normal data transmission and reception cannot be performed), which will cause the collapse of the chassis management system and seriously affect the system. reliability and stability. Node abnormalities are sometimes caused by physical wiring failures (short to ground), and some are caused by abnormal operation of devices on the bus. [0003] For example, in the use of the Advanced Telecommunications Computing Architecture (ATCA, Advanced Telecommunications Computing Architecture) specification, the Intelligent Platform Management Bus (IPMB, Intelligent Platform Management Bus) communication bus adopts the Inter-Integrated Circuit Inter...
