Problems solved by technology

[0002] The current VPX architecture computers are mostly used in occasions with high environmental adaptability requirements such as high temperature, high humidity, and vibration. The current VPX architecture computers mainly include power boards, main control cards, and service boards. All business boards are connected to the main The control card is used to complete specific services. When the main control card fails, it will cause all the business cards to fail to operate normally.

Embodiment Construction

[0025] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0026] like figure 1 As shown, a dual-control master-slave switching method based on VPX architecture includes the following steps:

[0027] Step 1, the system is powered on, the FPGA startup is completed, the FPGA determines the master-slave relationship of the dual master control, and initially establishes the master-slave relationship;

[0028] Step 2: Start the BMC. After the BMC is started, through the heartbeat synchronization between the BMCs and the status of the single board, determine the master-slave relationship of the dual master control again, and complete the reconfirmation of the master-slave relationship of the dual master control;

[0029] Step 3: After the CPU is started, boot into the operating system, and confirm the m...

Abstract

The invention discloses a double-control master-slave switching method based on a VPX architecture, and the method comprises the following steps: 1, electrifying a system, completing the starting of an FPGA, judging the master-slave relation of double master controls through the FPGA, and preliminarily building the master-slave relation; step 2, starting the BMC, after the BMC is started, judging the master-slave relationship of the double master controllers again through heartbeat synchronization and single board state between the BMCs, and confirming the master-slave relationship of the double master controllers again; and step 3, after the CPU is started, the CPU is guided to enter an operating system, and the master-slave relationship of the double controls is confirmed through CPU interaction state synchronization between the double controls. By the adoption of the double-control master-slave switching scheme, when any master control card breaks down, all service systems can be seamlessly switched to the other master control card, and the reliability of the system is greatly improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a dual-control master-slave switching method based on VPX architecture. Background technique [0002] The current VPX architecture computers are mostly used in occasions with high environmental adaptability requirements such as high temperature, high humidity, and vibration. The current VPX architecture computers mainly include power boards, main control cards, and service boards. All business boards are connected to the main If the main control card is used to complete specific services, when the main control card fails, it will cause all the service boards to fail to operate normally. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, provide a kind of dual control master-slave switching method based on VPX framework, comprise the steps: [0004] Step 1, the system is powered on, the FPGA startup is completed, the...
