The network central control device 10 is connected to the multimedia device 20 and the cloud server 40, and the feedback device 30 is connected to the multimedia device 20.
Optionally, the multimedia device 20 further comprises an electronic component 21. Wherein the electronic component 21 is arranged corresponding to the feedback device 30. For example, when the electronic component 21 is a projection device, the feedback device 30 may be a camera. For another example, when the electronic component 21 is a power amplifier speaker, the feedback device 30 may be a sound pickup.
It should be noted that the electronic component 21 includes, but is not limited to, a projection device, a power amplifier, and the feedback component 30 includes, but is not limited to, a camera, a sound pickup, and the like.
In one embodiment of the invention, the network central control device 10 is configured to send a detection instruction containing the component identifier to the multimedia device 20 in the rest state. Further, the multimedia device 20 parses the detection instruction to obtain the component identifier, and sends a detection mode operation instruction to the electronic component 21 and the feedback device 30 corresponding to the component identifier.
As a possible implementation manner, the usage state of the classroom may be detected, for example, a human body is detected around the multimedia device 20, and if no human body is detected, the multimedia device 20 is determined to be in the rest state.
Optionally, the detection instruction may include a component identification and an operating mode. For example, the operation mode may be a standard mode and a power saving mode. For another example, the operation mode may be a stereo mode, a parallel mode, a bridge mode, etc.
As an example, the electronic component 21 includes a and B, corresponding component identifications are 1 and 2, respectively, and corresponding feedback devices are a and B. The network central control apparatus 10 first detects whether the electronic component a is operating, and transmits an instruction to detect a standard mode and a component identification 1 to the multimedia apparatus 20 when the electronic component a is in a non-operating state. Further, the multimedia device 20 transmits an instruction to detect the standard mode operation to the electronic component a and the feedback device a according to the component identification 1.
The component identifier may be in a digital form, a text form, or the like, and is not limited herein.
It is understood that the multimedia device 20 may include a plurality of electronic components 21, for example, one multimedia device may include a desktop projector, a floor-type projector, and the like, and therefore, the detection system of the multimedia device according to the embodiment of the present invention may select a corresponding electronic component for detection according to the component identifier.
Optionally, when the network central control device 10 is connected to a plurality of multimedia devices 20, in order to more intuitively and conveniently select the corresponding multimedia device 20, the network central control device 10 may further include a display screen, so as to display a location map of the multimedia device in a rest state through the display screen.

In an embodiment of the present invention, the multimedia device 20 is further configured to extract first feature data of the detection data, obtain second feature data of pre-stored reference data according to the component identifier, calculate a similarity between the first feature data and the second feature data, determine a detection result of the electronic component corresponding to the component identifier according to the similarity, and feed back the detection result to the network central control device 10.
As an example, taking the projection device as an example, the multimedia device 20 may perform feature extraction on detected picture data preset by the projection device, acquire image feature data of the picture as second feature data, such as RGB color feature data, and store the component identifier of the projection device and the image feature data in the database. Further, after receiving the image data fed back by the camera, the multimedia device 20 may extract RGB color feature data of the image data as first feature data, and query the database according to the component identifier to obtain second feature data. Further, the similarity between the first characteristic data and the second characteristic data is calculated through a correlation algorithm, when the similarity is greater than or equal to a preset threshold value, it is determined that the projection device is operating normally, and the detection result is sent to the network central control device 10.
The preset threshold of the similarity may be determined according to a large amount of experimental data, or may be set according to actual needs, for example, may be set to 80%, which is not limited herein.
Further, in consideration of the possibility of an error in the feedback device 30 when acquiring the detection data, in order to improve the accuracy of the detection result, a first preset threshold and a second preset threshold may be set respectively to determine the detection result of the electronic component 21 corresponding to the component identifier.
As an example, the first preset threshold is 80%, the second preset threshold is 75%, and when the similarity is greater than 80%, the electronic component is determined to be normal; when the similarity is less than or equal to 80% and greater than 75%, determining the detection result as re-detecting the electronic component; and when the similarity is less than or equal to 75%, determining that the detection result is the electronic component fault.

For another example, the network central control device 10 may send the detection result to the cloud server 40, and then the cloud server 40 sends the detection result to the mobile terminal of the registered user. Therefore, automatic detection of the multimedia equipment is realized, so that an administrator can timely and quickly acquire a detection result, and the timeliness of detection of the multimedia equipment is ensured.
The detection system of the multimedia device in the embodiment of the invention receives the detection instruction sent by the control device in the network through the multimedia device, and sends the detection mode working instruction to the electronic component and the feedback device corresponding to the component identifier. And then, the electronic component sends preset detection data, and the feedback equipment receives the detection data and feeds the detection data back to the multimedia equipment. Further, the multimedia device extracts first feature data of the detection data, acquires second feature data of pre-stored reference data according to the component identifier, and determines a detection result of the electronic component according to the similarity between the first feature data and the second feature data. Therefore, automatic detection of the multimedia equipment is realized, the detection efficiency is improved, and the manual workload is reduced.
