Specifically, the display signal processing module can be used to generate the second valid signal in the embodiment of the present invention, and the safety signal generating module can generate the first detection code in the embodiment of the present invention. Further, optionally, it can also generate a second safety diagnostic signal corresponding to the above-mentioned first safety diagnostic signal. The second safety diagnostic signal has different transmission trajectory information from the first safety diagnostic signal.

Figure 4 The multi-dimensional failure detection method for display signals described above can be applied to a display device, and specifically, can be applied to a display signal transmission system of a display device, and the display signal transmission system can be as follows: Figure 2 As shown, please refer to Example 1 for the supplementary description of the display signal transmission system, which will not be described in detail in the embodiment of the present invention. Further, optionally, the method can also be applied to smart devices associated with the above-mentioned display signal transmission system, which include but are not limited to battery devices, cloud devices, edge computing devices, relay devices, base station devices, city management devices, and one or more of smart network devices, which are not limited in the embodiment of the present invention. Figure 4 As shown, the multi-dimensional failure detection method of the display signal may include the following operations:

[0115] 201. Analyze a first safety diagnostic signal and a first valid signal in a received first display signal, wherein the first safety diagnostic signal is in a blanking area of ​​the first display signal;

[0116] 202. Analyze transmission status information of the first display signal according to the first safety diagnosis signal and the first valid signal, where the transmission status information is used to indicate a state change during the transmission of the first display signal;

[0117] 203. Determine, according to the transmission state information, whether the first display signal satisfies at least one target failure condition in a preset multi-dimensional failure condition set;

[0118] 204. When it is determined that the first display signal satisfies the target failure condition, it is determined that the first display signal has a failure condition that matches the target failure condition.

[0119] In the embodiment of the present invention, for the supplementary description of step 201 to step 204, please refer to the supplementary description of step 101 to step 104 in the first embodiment, and the embodiment of the present invention does not specifically limit this.

[0121] 206. Calculate a failure response degree coefficient according to the failure richness value and a preset failure richness threshold, the failure response degree coefficient corresponds to a failure response measure, and the failure response measure includes at least one of switching a display signal, sending a display failure prompt message, remote assistance display, remote prompt display information, and remote guidance repair.

[0122] In an embodiment of the present invention, optionally, the above-mentioned switching display signal may be a switching backup display signal. Specifically, the style information such as the color splendour of the backup display signal may be simpler than that of the above-mentioned first display signal. Further optionally, the prompt method for sending the display failure prompt information may be a combination of one or more of sound, light and image. Further optionally, the above-mentioned remote assistance display may be in the form of remote assistance, switching the display signal to other screens in the application scenario, such as by transferring the domain controller. Further optionally, the remote prompt display information may be to explain the display information and its corresponding failure status in the form of voice, text and the like. Further optionally, the above-mentioned remote guidance repair may be to repair the above-mentioned display signal failure problem in the form of remote guidance, which is more inclined to guided repair.

[0123] It can be seen that the implementation of this optional embodiment can, after determining that the first display signal has a failure condition that matches the target failure condition, further calculate the failure richness value used to represent the multi-dimensional failure degree of the first display signal according to the specific failure condition, thereby calculating the failure response degree coefficient according to the failure richness value and the preset failure richness threshold, and then determining the failure response measure corresponding to the failure response degree coefficient to match at least one of the failure response measures including switching display signals, sending display failure prompt information, remote assistance display, remote prompt display information, and remote guidance repair. On the basis of improving the accuracy, real-time and comprehensiveness of multi-dimensional failure detection of display signals, it is possible to further improve the matching accuracy and scientificity of failure response measures, which is conducive to improving the safety of display signal use in application scenarios.

[0128] A first detection code is generated according to all blanking area detection codes.

[0129] It can be seen that the implementation of this optional embodiment can generate the original transmission signal of the first display signal, that is, the second valid signal of the second display signal, according to the target transmission link and the target transmission protocol, and obtain the multi-dimensional verification code of each second signal frame by performing a multi-dimensional verification based on a preset multi-dimensional verification algorithm on each second signal frame of the second valid signal. The blanking area detection code of each blanking area is generated by the multi-dimensional verification codes of all second signal frames corresponding to each blanking area, and the first detection code is further generated based on all the blanking area detection codes, thereby improving the generation accuracy and scientificity of the first detection code, and can effectively reflect the multi-frame joint verification of the first display signal, which is conducive to further improving the accuracy of multi-dimensional failure detection of the display signal.

[0131] See also Figure 5 , Figure 5 1 is a schematic diagram of a multi-dimensional failure detection device for display signals disclosed in an embodiment of the present invention. The multi-dimensional failure detection device for display signals can be applied to a display device, and specifically, can be applied to a display signal transmission system of a display device. The display signal transmission system can be as follows: Figure 2 As shown, please refer to Example 1 for the supplementary description of the display signal transmission system, which will not be described in detail in the embodiment of the present invention. Further, optionally, the method can also be applied to smart devices associated with the above-mentioned display signal transmission system, which include but are not limited to battery devices, cloud devices, edge computing devices, relay devices, base station devices, city management devices, and one or more of smart network devices, which are not limited in the embodiment of the present invention. Figure 5 As shown, the multi-dimensional failure detection device for display signals may include:

[0132] The parsing module 301 is used to parse the first safety diagnostic signal and the first valid signal in the received first display signal, wherein the first safety diagnostic signal is in the blanking area of ​​the first display signal;

[0135] The determination module 304 is configured to determine that the first display signal has a failure condition matching the target failure condition when the determination module determines that the first display signal meets the target failure condition.

[0136] It can be seen that the implementation of the embodiment of the present invention can further analyze the transmission status information used to represent the state change during the transmission of the first display signal by parsing the first valid signal in the received first display signal and the first safety diagnosis signal in the blanking area of ​​the first display signal, and judge whether the first display signal satisfies at least one target failure condition in the preset multi-dimensional failure condition set according to the transmission status information. When it is judged that the first display signal satisfies the target failure condition, it is determined that the first display signal has a failure condition matching the target failure condition. Compared with the prior art, the blanking area in the display signal can be fully utilized to add a safety mechanism to the system without reducing the original display performance of the display system, that is, the accuracy of the failure detection of the display signal is improved while ensuring the transmission quality of the display signal and the user experience. Moreover, compared with the general protocol that only uses the verification technology, the present solution can cover the detection of more failure modes, further improving the accuracy and comprehensiveness of the failure detection of the display signal. At the same time, compared with the failure detection scheme of the display signal at a specific node such as the display function initialization stage and the terminal node before sending the display, the present solution can improve the real-time and full-link troubleshooting accuracy of the display signal failure detection, which is conducive to improving the transmission stability and security of the display signal and protecting the life and property safety of the user.

[0137] In an embodiment of the present invention, as an optional implementation, the first safety diagnostic signal includes a first detection code and transmission trajectory information of the first display signal, the first detection code is calculated based on the original transmission signal of the first display signal and the first multi-dimensional calculation processing algorithm, and the transmission trajectory information is dynamically generated based on the transmission trajectory of the first display signal;

[0141] The transmission status information of the first display signal is analyzed according to the first safety diagnosis signal and the second detection code.

[0142] It can be seen that the implementation of this optional embodiment can match the second multi-dimensional computing and processing algorithm of the first valid signal according to the first multi-dimensional computing and processing algorithm, calculate the second detection code corresponding to the first valid signal and the first detection code according to the second multi-dimensional computing and processing algorithm, and analyze the transmission status information of the first display signal according to the first safety diagnostic signal and the second detection code, which can further improve the analysis accuracy and analysis breadth of the transmission status information, and is conducive to improving the failure detection accuracy and real-time performance of the display signal.

[0143] In this optional embodiment, as an optional implementation manner, the above-mentioned transmission trajectory information includes at least one of signal frame counter information, signal frame identification information, and signal transmission timestamp information. The judgment module 303 judges whether the first display signal satisfies at least one target failure condition in the preset multi-dimensional failure condition set according to the transmission state information. The specific manner includes:

[0144] Determining whether the second detection code matches the first detection code;

[0145] Determining whether the transmission trajectory information matches the preset expected transmission trajectory information, the preset expected transmission trajectory information corresponds to the transmission trajectory information;

[0146] When it is determined that the second detection code does not match the first detection code and / or the transmission trajectory information does not match the preset expected transmission trajectory information, it is determined that the first display signal satisfies at least one target failure condition in the preset multi-dimensional failure condition set.

[0147] It can be seen that the implementation of this optional embodiment can further determine whether the first display signal satisfies at least one target failure condition in the preset multi-dimensional failure condition set by judging whether the second detection code matches the first detection code and judging whether the transmission trajectory information matches the corresponding preset expected transmission trajectory information, and can further improve the accuracy and comprehensiveness of failure detection of the display signal by covering the detection of more failure modes.

[0148] In this optional embodiment, as another optional implementation, the specific manner in which the determination module 304 determines whether the first display signal has a failure condition that matches the target failure condition includes:

[0149] Determine abnormal matching information of the first display signal, where the abnormal matching information includes at least one of abnormal position information, mismatch value information, and abnormal transmission node information in the first display signal that causes the first display signal to meet a target failure condition;

[0155] The first display signal is analyzed to determine whether there is a failure condition matching the target failure condition according to the abnormal matching sub-information of all target signal frames.

[0156] It can be seen that the implementation of this optional embodiment can further determine, based on the abnormal matching information, at least one target signal frame that makes the first display signal meet the target failure condition among all the first signal frames of the first display signal, so that for each target signal frame, based on the abnormal matching information, the abnormal matching sub-information used to indicate that the target signal frame is at least one of a damaged abnormal match, a frozen abnormal match, a missing abnormal match, an unexpectedly inserted abnormal match, and a misaligned match is analyzed, and then based on the abnormal matching sub-information of all target signal frames, the first display signal is analyzed for failure conditions that match the target failure condition, which can further improve the granularity of failure detection of the display signal, and further improve the comprehensive analysis degree of multi-dimensional failure detection of the display signal, and improve the accuracy of multi-dimensional failure detection of the display signal.

[0161] A first detection code is generated according to all blanking area detection codes.

[0162] It can be seen that the implementation of this optional embodiment can generate the original transmission signal of the first display signal, that is, the second valid signal of the second display signal, according to the target transmission link and the target transmission protocol, and obtain the multi-dimensional verification code of each second signal frame by performing a multi-dimensional verification based on a preset multi-dimensional verification algorithm on each second signal frame of the second valid signal. The blanking area detection code of each blanking area is generated by the multi-dimensional verification codes of all second signal frames corresponding to each blanking area, and the first detection code is further generated based on all the blanking area detection codes, thereby improving the generation accuracy and scientificity of the first detection code, and can effectively reflect the multi-frame joint verification of the first display signal, which is conducive to further improving the accuracy of multi-dimensional failure detection of the display signal.

[0163] In another optional embodiment, optionally, as Figure 6 As shown, the device may also include:

[0164] A calculation module 305, used to calculate a failure richness value of the first display signal according to the failure condition, where the failure richness value is used to represent a multi-dimensional failure degree of the first display signal;

The failure response degree coefficient corresponds to the failure response measure. The failure response measure includes at least one of switching display signals, sending display failure prompt information, remote assistance display, remote prompt display information, and remote guidance repair.

[0166] It can be seen that the implementation of this optional embodiment can, after determining that the first display signal has a failure condition that matches the target failure condition, further calculate the failure richness value used to represent the multi-dimensional failure degree of the first display signal according to the specific failure condition, thereby calculating the failure response degree coefficient according to the failure richness value and the preset failure richness threshold, and then determining the failure response measure corresponding to the failure response degree coefficient to match at least one of the failure response measures including switching display signals, sending display failure prompt information, remote assistance display, remote prompt display information, and remote guidance repair. On the basis of improving the accuracy, real-time and comprehensiveness of multi-dimensional failure detection of display signals, it is possible to further improve the matching accuracy and scientificity of failure response measures, which is conducive to improving the safety of display signal use in application scenarios.
