Description

server system

The present invention relates to a system for processing electronic digital data, in particular to a servo system which is interrupted due to abnormal operation.

Referring to Fig. 1, the existing servo system comprises a system chip 7, a plurality of management modules 8, a plurality of peripheral components 1, the system chip is a central processing unit 71, and a platform path controller electrically connected to the central processing unit 72. Each management module 8 separately monitors the operation status of several peripheral components 1, and when a peripheral component 1 occurs, for example, a failure event, the corresponding management module 8 triggers a system management interrupt, and transmits the interrupt via the platform path controller 72. The corresponding signal is sent to the central processing unit 71, and then the central processing unit 71 provides the corresponding service type

However, in the existing architecture design, when a fault event occurs in each peripheral component 1, the corresponding management module 8 must trigger a system management interrupt through an independent physical circuit, such as a system management interrupt (SMI: System Management Interrupt) circuit 9 That is to say, the number of physical lines electrically connected to the platform path controller 72 of each management module 8 and the system chip 7 must be the same as the number of peripheral components 1 electrically connected to the management module 8, and according to the management module 8 also needs to trigger system management interrupts according to their own needs. The number of interrupt types is the same as the number of physical lines electrically connected to the platform path controller 72 of the system chip 7. For example: when the number of management modules 8 is M, each management module The number of peripheral components 1 electrically connected to 8 is N, and the number of interrupt types that each management module 8 itself needs to trigger system management interrupts is P, then the number of physical lines of all management modules electrically connected to the platform path controller 72 There will be up to M×(N+P), because each physical line will occupy at least 8 pins of the management module, so that the space for configuring other components or lines inside the servo system will be limited Moreover, the number of pins that can be configured for other functions of the management module 8 is also limited, so there is a need for improvement.

Therefore, the object of the present invention is to provide a servo system that can improve the disadvantages of the prior art.

The corresponding electrical connection of the transmission interface is between the management module and the system module.

When the management module detects an interrupt event, the management module generates an interrupt trigger signal and a corresponding interrupt code according to the interrupt event, and transmits the interrupt trigger signal to the system module through the corresponding transmission interface .

The system module sends an inquiry signal to the management module according to the received interrupt trigger signal.

The management module transmits the interrupt code corresponding to the interrupt event to the system module.

The system module looks up and executes the corresponding service type from the comparison table according to the received interrupt code.

The effect of the present invention is that when the management module detects an interrupt trigger signal, the system module switches to the system interrupt mode and sends an inquiry signal to the management module through the transmission interface in a polling manner, and The corresponding service type is searched according to the error code returned by the management module that detected the interruption event, thereby greatly reducing the physical lines for system module configuration to detect abnormal operation events.

The number of types of interrupt trigger signals that are triggered to generate interrupt trigger signals is irrelevant, so the number of physical lines between the system module 2 and all management modules 3 will only change according to the number of management modules that are designed to send interrupt trigger signals, for example, by The number of management modules designed to send interrupt trigger signals is M, then the number of physical lines related to system management interruption between these management modules and the system module is 2×M, and the number of these lines is far Each management module in the prior art needs to design a physical line related to system management interruption for each different service type, that is to say, when there are M management modules in the prior art that all have N types of service requirements , then the previous technology needs to design N×M physical lines on the system module for the implementation of the system management interruption mechanism, so the implementation of the technology of this case will greatly reduce the number of connections between the system module 2 and all management modules 3 for the implementation of system management Interrupt the number of configured physical lines, that is to say, this embodiment can simplify the design, reduce the setting of the lines related to the servo system, improve the compatibility between platforms, and then shorten the development time schedule and reduce costs, so it is true Reach the creative purpose of the present invention.
