Embodiment Construction

[0051] According to the Compact PCI bus protocol, when a certain data transmission begins, the master device needs to send the address of the target single board at the same time. Using this feature, in order to realize the purpose of locating the faulty single board and making the faulty single board return to normal in the present invention, the key of the present invention It is to add a function module in the system, which realizes the real-time monitoring of the operation on the bus. This module acquires and stores the address of the target board. When the number of retries of the board corresponding to the address exceeds the preset When the upper limit is reached, the functional module generates a reset signal to the faulty single board, so that the faulty single board returns to normal.

[0052] The present invention will be described in detail below with reference to the accompanying drawings.

[0053] Referring to FIG. 4 , it is a composition diagram of an embodiment...

Abstract

One method using for insulating bus failure can get address of the current visited goal board from Compact PCI bus and judge whether the tautology response happened on the Compact PCI bus. If it is true, add one count unit to the tautology counter according to goal board address. Judge whether the count overruns the limit of the tautology time, and if it is true, send replacement order to goal board. Meanwhile, it sends intermit signal to processor and the failure message send by the latter according to the address of the goal board to remind servicing people. It also offers one set of equipment to insulate bus failure and one board. It can renew the broken-down equipment of the system and is easy for exterior maintenance.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a method and system for isolating bus faults. Background technique [0002] The PCI (Peripheral Component Interconnect) bus was released by Intel Corporation in 1992. It complies with the increasing demand for bus bandwidth of multimedia computers. It has plug-and-play, processor-independent, and good scalability. And other advantages, and can expand the bus width or operating frequency according to the needs of the application, and maintain software compatibility, so it has been widely promoted and applied. [0003] With the promotion of the PCI bus in the field of personal computers, it has gradually been applied to other fields, such as servers, notebook computers, embedded systems, etc. In 1994, PICMG (PCI Industrial Computer Manufacturers Group, PCI Industrial Computer Manufacturers Association) released the Compact The PCI (CompactPeripheral Component Interconnec...
