Problems solved by technology

[0004] 1. The inter-board protocol depends on the driver of the protocol stack and Ethernet. For most general-purpose operating systems, the driver of the protocol stack and Ethernet can only be used at a later stage of system startup, so in the main system The status of the subordinate system can only be known at the later stage of startup, and there is a lag in the response to the status of the subordinate system;
[0005] 2. In some cases, the inter-board agreement confuses the shutdown or crash status of the subordinate system with the status of link abnormality, and cannot fully identify the shutdown or crash status of the subordinate system
If the Ethernet uses the inter-board protocol to confuse the abnormal link of the subordinate system with the status of crash or shutdown, and the user switches the main system to the control port of the subordinate system when the subordinate system is in crash or shutdown, at this time, no matter what characters are input Subordinate systems do not respond, and the user interface is very unfriendly, so the main system cannot distinguish the status of the subordinate system such as crash, shutdown, and link abnormality through the Ethernet port

Embodiment Construction

[0025] FIG. 2 is a flow chart of Embodiment 1 of the method for acquiring system status in the present invention. As shown in Figure 2, this embodiment includes:

[0026] Step 1: the first system sends detection information to the second system via the basic input and output interface of the second system;

[0027] Step 2: The first system judges whether it has received the return information from the second system within the predetermined time. If no return information is received, it will prompt the second system for abnormal status information; otherwise, it will receive the return information and know that the second system is in normal state. state.

[0028] This embodiment provides a method for obtaining system status by using the basic input and output interface. The first system is connected to the second system through the basic input and output interface, and the second system connects the basic input and output of the serial port or parallel port corresponding to t...

Abstract

The related method for acquiring system state comprises: the system sends detection message through I / O interface of the second system, and decides whether receiving the response in pre-et time; if not, it prompts the second system is on abnormal state. This invention avoids operating a system on abnormal state, and benefit to successive operation.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and device for acquiring system status. Background technique [0002] In a multiprocessor system, the main system (Main-system) and the subordinate system (Sub-system) have independent processors and software systems. The two systems exchange data and control information through the relatively connected serial port and Ethernet port. As shown in Figure 1, in order to realize the centralized management of the multiprocessor system without changing the physical connection mode of the system, the console of the user PC is connected to the control port (console) of the main system, the control port in Figure 1 is physically a serial port ) to control the main system through the control port. At the same time, another serial port of the main system is connected to the control port of the subordinate system. When the user needs to control the subordinate system, the serial ...
