Problems solved by technology

Although this commercial platform can provide convenience for fault detection, recovery, and fault debugging and diagnosis of the system platform, it is difficult to detect bugs (errors) in large-scale control systems, especially OS (operating system) and application-level bugs, by relying on this information. (error) positioning analysis and debugging, so non-platform-related errors often appear uncontrollable, and this type of error is difficult to avoid in the actual system, especially for large and complex communication systems even more so
In addition, although the general-purpose OS (operating system) with a high-reliability protection mechanism can meet the needs of system protection functions such as hot backup and restart recovery, it is precisely because of this generality that it inevitably brings problems when the system is working normally. The protection load is too large and the recovery time is long, which is relatively cumbersome for a dedicated communication system that requires high real-time performance, and even cannot meet the needs

Embodiment Construction

[0007] Such as figure 1 As shown, the present invention is provided with an exception handling module 1 in the driver program and the application layer of the main processor of the communication system, to support functions such as exception detection, exception handling, exception recovery, exception strategy control, and exception information storage of the system processor ; In each application module 4, there is a detection point unit 2 for supporting abnormal detection and abnormal recovery. Through the exception handling module 1, the detection point unit 2 in the application module, and the system control module 3, the protection of the system software is jointly completed, and the external debugging environment and other modules cooperate to complete the debugging of the software system, thereby reducing the system service failure time and improving stability.

[0008] The exception handling module 1 is composed of an interface unit 15 , an exception detection and ana...

Abstract

In the system control module of the main processor of the communication system is set an exception processing module for supporting the functions of exception detection, exception handling, exceptingrecovery, exception strategy control and exception information storage of system processor, and in every application program module a detection point unit is set for supporting exception detection and exception recovery. The adoption of said invention can make the communication system normally and better work under the condition of that its normal load is less than 70%, and has the great significance for debugging system and finding latent error.

Description

(1) Technical field [0001] The invention relates to a trap-based protection and debugging device for a communication system (2) Background technology [0002] The designs of existing communication systems are all based on commercial development platforms, and these commercial development platforms generally only provide some error information related to the platform for abnormal situations in various systems. Although this commercial platform can provide convenience for fault detection, recovery, and fault debugging and diagnosis of the system platform, it is difficult to detect bugs (errors) in large-scale control systems, especially OS (operating system) and application-level bugs, by relying on this information. (error) positioning analysis and debugging, so non-platform-related errors often appear uncontrollable, and this type of error is difficult to avoid in the actual system, especially for large and complex communication systems Even more so. In addition, although ...
