Embodiment Construction

[0026] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] refer to figure 1 , a schematic flow chart of the first embodiment of the fault tracing method of the display terminal in the present invention, the fault tracing method of the display terminal includes:

[0028] Step S10, dividing a part of the physical memory of the display terminal and defining it as a bare area for storing event information;

[0029] In this embodiment, the Linux operating system is taken as an example. When the display terminal is started, when the physical memory of the display terminal is in the initialization stage of mapping, the physical memory is divided. A part of the area is reserved in the physical memory, and this area is defined as a bare area, which is used to record and store traces and states of operation behaviors of all software in the display terminal. In the above proce...

Abstract

The invention discloses a fault backtracking method of a display terminal. The method includes the following steps: partitioning a part of area in physical memory of the display terminal to define thesame as a bare area used for storing event information; obtaining the event information in the bare area; and determining a fault of the display terminal when event information at an end position ofthe bare area is not resetting information. The invention also discloses a computer-readable storage medium and the display terminal. According to a scheme of the fault backtracking method of the display terminal of the invention, all software behaviors or software states which are in a system and are recorded or stored through the bare area are more comprehensive, various details cannot be misseddue to excessive network server data pressure, and high-precision monitoring and backtracking are realized; and at the same time, a manner of collecting the event information offline does not dependon a network server, and a case where the event information of the fault cannot be collected cannot occur due to network disconnection.

Description

technical field [0001] The present invention relates to the technical field of fault detection, in particular to a fault traceback method for a display terminal, a computer-readable storage medium, and a display terminal. Background technique [0002] Embedded systems have been widely used in various intelligent display terminals, such as televisions, and a large part of them are Linux operating systems. Due to the large number, it is very difficult to collect fault information when abnormal faults occur in these systems, especially for occasional abnormalities, or abnormal resets, task deadlocks and other information collection is even more difficult. [0003] In the prior art, since the operating system of the display terminal is generally connected to the Internet through Wi-Fi, a network server is usually used to collect or monitor event information in real time. But the disadvantage is that when the number of display terminals is large, the data pressure on the server ...
