Abstract

The invention discloses an operating system kernel level real-time dongle monitoring device and a monitoring method thereof, which comprises a dongle module. The device is characterized in that the dongle module is arranged in a system kernel and carries out the operations of registration, canceling of the registration and reset of applications via kernel level drivers. The kernel dongle at least includes a timing module which is used for detecting whether each registered application is overtime when the time set in a timer is due; when the registered application is overtime, the dongle module starts a reset module to do the reset operation on the operating system; when the registered application is not overtime, the time set in the timing module continues to cycle; and when the time set in the timer is not due, the dongle module carries out corresponding operations according to the applications starting or canceling the registration module or resetting the module. Via the drivers operated in the kernel, the device finishes the real-time monitoring on the applications and has simple operation and high real-time capability.

Description

technical field [0001] The invention belongs to the technical field of application program monitoring of embedded systems, in particular to a method based on the realization of an embedded system kernel driver and a monitoring application program, especially a method for monitoring application programs by using a kernel watchdog (Watchdog) method. Background technique [0002] In recent years, with the continuous deepening of informatization in various industries, embedded systems have been widely used in network communications, consumer electronics, manufacturing, industrial control, security systems and other fields due to their customizability. [0003] In order to adapt to the increasing functional density of software, the number of applications must become larger and larger, which brings many unstable factors to the reliability of the system. Due to the characteristics of the embedded system software itself, after a long period of operation, there may be applications T...
