Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] The invention provides a VxWorks program automatic discrimination and operation method, monitors the slave machine through the heartbeat packet process, re-runs the program when the slave machine fails, and tests whether the network is smooth through the delay heartbeat test method, and passes the most The optimal heartbeat binary search method is used to find the optimal heartbeat value. When the network is not smooth, the fast heartbeat method is used ...

Abstract

The invention discloses a VxWorks program automatic discrimination and operation method, which comprises a slave computer and a host computer, a main program and a heartbeat packet process for monitoring the operation state of the main program are operated in the slave computer, the host computer performs heartbeat processing and sends a query command to the heartbeat packet process, processing isnot performed when normal feedback is obtained, when insufficient resource feedback is obtained, an operation command for reducing the resource demand of the master program system is sent to the slave computer, an operation command created by the process is sent to the slave computer when feedback of program crash is obtained, and the slave computer is reconnected when heartbeat response of the host computer to the slave computer fails. According to the invention, a slave host program is monitored through the heartbeat packet process, and normal operation of the system is ensured.

Description

technical field [0001] The invention relates to the field of computer operating systems, in particular to a method for automatic identification and operation of a VxWorks program. Background technique [0002] The VxWorks operating system is an embedded real-time operating system (RTOS), which is a key component of the embedded development environment. The VxWorks operating system has high real-time performance and is widely used in engineering. Usually, there are multiple computers in a system, and multiple computers operate according to a certain master-slave relationship. When the system is running normally, usually multiple VxWorks programs will work together with each other. If a VxWorks program of a certain computer fails, it will affect the performance and normal operation of the system. [0003] Therefore, a reliable VxWorks program automatic identification and running method is needed. When a VxWorks program of a slave machine is down, the host computer in the syst...
