The monitoring equipment provided by the embodiment of the invention can automatically identify the network data, so that a tired machine can replace manual auditing, and human error can be effectively avoided.
In order to facilitate understanding, on the basis of the foregoing embodiment, the embodiment of the present invention further provides another electronic screen information monitoring device, where, when the authentication result of the video stream is that the authentication passes, the network data processing unit transfers network data acquired by the first network card from the broadcast control host to the second network card, where the network data processing unit is further configured to: transmitting the network data acquired by the first network card from the broadcasting control host to the information authentication unit; the information authentication unit is also used for performing authentication processing on the network data to obtain an authentication result corresponding to the network data, and feeding back the authentication result to the network data processing unit; and the network data processing unit is also used for sending the network data to the second network card when the authentication result of the network data is that the network data passes the authentication, and sending the network data to the electronic screen unit through the second network card so that the electronic screen unit displays the display content included in the network data.
When the network data is acquired through the first network card, the network data processing unit and the information identification unit of the monitoring equipment process the program. The network data processing unit is used for analyzing the network data, recovering the picture information corresponding to the network data and transmitting the picture information to the information identification unit; the information authentication unit is used for performing authentication processing on the picture information according to a pre-stored information authentication algorithm to obtain an authentication result corresponding to the network data, and feeding back the authentication result to the network data processing unit. When the information authentication unit authenticates the picture information of the network data, if the information authentication algorithm does not find bad content, the authentication result corresponding to the picture information is characterized as that the picture information passes through authentication, and at this time, the network data processing unit can completely forward all the network data to the designated electronic screen receiving card through the second network card.
The network data processing unit not only transmits the network data formed by processing the video stream by the broadcasting control host to the second network card when the video stream data passes through the identification in the electronic screen information editing process, but also transmits the network data to the second network card when the identification result of the network data is that the identification passes through, and the monitoring equipment carries out information identification on the content of the electronic screen before and after the transmission, so that the data transmitted to the electronic screen unit is ensured to have no bad information, and bad content error playing can be effectively avoided.

The method specifically comprises stopping sending the network data to the second network card when the authentication result of the network data is that the authentication fails, and stopping forwarding the network data to the second network card when the authentication result of the video stream is that the authentication fails.
Specifically, if the information authentication algorithm finds bad content in the network data, the network data processing unit receives a feedback result that the network data authentication does not pass, at this time, the network data processing unit stops forwarding the network data to the second network card, at this time, the network data will not be received by the electronic screen receiving card, and bad video content can be avoided being played. Further, the monitoring device is configured with an operation and maintenance platform, the network data processing unit can also feed back network data abnormality reminding to the user through the operation and maintenance platform based on the authentication without feedback, so that the user can process the network data in the broadcasting control host in time until the internal operation and maintenance platform of the monitoring device is restored manually, and the network data processing unit can continue to execute work.
In a specific implementation, the video acquisition unit may include an HDMI video acquisition card, and the broadcast control host needs to manually edit the program on the broadcast control host at the present of the broadcast section. The display of the broadcast control host can see the content of the program, and the content of the program can be sent to the content of the electronic screen. Therefore, the embodiment of the invention can also collect the video stream sent to the display of the broadcasting control host by the broadcasting control host through the video collecting unit so as to monitor the data of the video stream in the process of editing the program by the broadcasting control host. Specifically, since the broadcast control host is connected with the broadcast control host player through the video line, at the moment, a video converter can be installed on the video line, and the video acquisition unit of the monitoring equipment is connected with the video converter, so that the video acquisition unit of the monitoring equipment can acquire the same picture as the broadcast control host player. When the video acquisition unit acquires the video stream corresponding to the broadcasting control host, the video acquisition unit can periodically acquire pictures through the video acquisition card to generate pictures.
Furthermore, the video acquisition unit provided by the embodiment of the invention not only adopts a standard HDMI interface to acquire the video stream of the broadcasting control host, and uses the video converter to divide a path of video access monitoring equipment to acquire the display interface of the broadcasting control host, but also can be realized in the following manner according to the actual situation: a. if the broadcasting control host has a plurality of video interfaces, the video converter can be omitted, and the video interfaces are directly connected with the video acquisition unit; b. if the video interface of the broadcasting control host is VGA, SDI, DVI, AV, RAC, the video interface can be converted into HDMI access through a converter.

When the acquisition card does not receive an effective video state, the acquisition interface corresponding to the video acquisition unit is considered to be not connected to a video source, namely, the acquired video data is invalid data, at the moment, the network data processing unit also stops sending the network data to the second network card, the network data corresponding to the program sent by the subsequent broadcast control host cannot be forwarded into the electronic screen receiving card, the monitoring equipment detection is avoided being skipped manually in a mode of pulling out the video line until the video line is recovered manually and recovered through the operation and maintenance platform inside the equipment. When the network data processing unit receives feedback that the authentication result of the network data or the video stream is characterized as failed authentication and the invalid instruction, the network data processing unit alarms through an operation and maintenance platform inside the network data processing unit, and in addition, the monitoring equipment can trigger an alarm when detecting any problem.

Specifically, the embodiment of the invention can use NLP, fuzzy matching, neural network algorithm, semantic segmentation and other technologies to identify the extracted text information with one or more of fuzzy matching, pinyin matching and synonym matching of the sensitive word stock so as to determine whether the sensitive word meeting the text threshold corresponding to the text information exists in the sensitive word stock. The sensitive word library stores various types of words such as pornography, abuse, politics and the like, and the information identification algorithm considers the pictures and the words as bad information when finding any word in the picture and the words matched with the sensitive word library.
