After acquiring the fault information, the device management platform 131 is further configured to acquire target device parameters of the target device, which are acquired by the target acquisition device and associated with the fault information, where the device management platform 131 generally maintains a device association table in which association relationships between the display screen and each device in the control system 10 are stored; the device management platform 131 may determine a target device associated with the fault information through the device association table, for example, when a certain display screen is blank, determine that the target device is a device of the display screen itself and a sending card, a receiving card, or the like associated with the display screen, and then obtain target device parameters of the target device acquired by the target acquisition device.

s211, checking whether the terminal sets program rotation;

s2111, when the rotation angle is greater than 0, outputs: the current rotation angle is x, and the terminal version is continuously checked;

s21111, when the version is higher than V3.7.2, determining that the version of the terminal is normal;

s21112, when the version is lower than V3.7.2, outputting a fault reason: program rotation causes a local black screen to be played; a proposed solution is given: please upgrade the terminal to the final version;

s212, checking whether the resolution of the terminal and the display screen is normal;

s2121, determining that the resolution is normal when the resolution of the display screen is less than or equal to the endogenous resolution;

s2122, when the resolution of the display screen is greater than the resolution of the internal source, outputting a fault reason: a resolution configuration error; a proposed solution is given: please adjust the resolution of the display screen to be less than the endogenous resolution of the terminal;

s2123, when the resolution ratio is not acquired, outputting a fault reason: resolution is not obtained; a proposed solution is given: please check whether the equipment is operating normally;

s22, the video source is an external source, and the following output is performed: the current video source type is an external source;

s221, checking whether the resolution of the external source is smaller than that of the display screen;

s2211, if yes, outputs the failure cause: the resolution of the external source is less than that of the display screen; a proposed solution is given: please start full screen zoom;

s2212, if the result is negative, determining that the resolution is normal;

and S2213, outputting the fault reason when the data cannot be acquired: the version does not support the acquisition of exogenous resolution; a proposed solution is given: please upgrade to the latest version for diagnosis.

It should be noted that the decision tree is only an example, and different decision priorities, decision logics, and the like may be set in practical application; meanwhile, due to the complex variability of equipment fault reasons, a decision tree structure and a preset rule in the fault diagnosis engine are not invariable but are dynamically updated, so that the accuracy of a diagnosis result is ensured, and the diagnosis efficiency is improved.
