Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, a clear, complete and detailed description of the present invention is provided below with reference to the accompanying drawings and detailed description.

In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

Referring to fig. 1, a flowchart illustrating steps of an embodiment of an information processing method according to the present invention is shown, and as shown in fig. 1, the method may be applied to a first server, and specifically may include the following steps:

step 101, responding to a monitoring resource request sent by a terminal device, and acquiring a monitoring resource list corresponding to the monitoring resource request.

In the embodiment of the present invention, the first server refers to a server that can obtain the corresponding monitoring resource according to the monitoring information. The first server may obtain the corresponding monitoring resource according to a request of the terminal device, or may obtain the corresponding monitoring resource at regular time. Optionally, the first server may set an inspection client, so as to inspect the acquired monitoring resource and acquire corresponding information. In addition, the first server can also accept login, setting modification, management and the like of the administrator authority account. The embodiment of the present invention is not particularly limited to this.

In the embodiment of the invention, the monitoring areas can be classified, the monitors in the same monitoring area are classified into the same directory, the monitoring information corresponding to the monitors in the same directory, such as monitoring ID, monitoring position, monitoring responsible person, monitoring serial number and the like, is classified into the same list, namely the monitoring resource list in the directory, and when the first server receives a monitoring resource request aiming at a certain directory, the monitoring resource list in the corresponding directory can be obtained.

In the embodiment of the present invention, the monitoring resource request may be triggered for at least one target monitoring area in the multiple monitoring areas, where each target monitoring area may correspond to one directory, each directory may correspond to at least one monitoring resource list, and each monitoring resource list includes at least one monitoring information corresponding to monitoring. In addition, different monitoring resource requests may also be triggered for the same target monitoring area, which is not specifically limited in the embodiment of the present invention.

For example, the first server responds to the monitoring resource request 1 for the B street of the beijing a district, and obtains a monitoring resource list AB corresponding to the monitoring resource request.

In the embodiment of the present invention, the process of receiving and responding to the monitoring resource request by the first server and then obtaining the corresponding monitoring resource list according to the monitoring resource request may be implemented in the internet or in the video network.

Step 102, traversing the monitoring resource list, and determining availability information corresponding to each monitoring resource in the monitoring resource list.

In the embodiment of the invention, after the monitoring resource list corresponding to the monitoring resource request is obtained, the monitoring resource list can be traversed, and the availability information corresponding to each monitoring resource in the monitoring resource list is determined. The video network can realize the transmission of end-to-end high-definition video data through a real-time high-definition video exchange technology, and is widely applied to the fields of high-definition video conferences, video monitoring, network teaching, live broadcasting and the like. When the monitoring resources are shot and transmitted through the video network, the monitoring information corresponding to the monitoring resources is stored in the monitoring resource list, so that the corresponding monitoring resources can be obtained in the video network according to the monitoring information. Optionally, other network protocols other than the video network may also be used to perform shooting and transmission of the monitoring resource, and this is not particularly limited in the embodiment of the present invention.

In the embodiment of the invention, due to the difference of different monitored transmission lines, network transmission conditions and the like, the problems of data loss, damage and the like of different monitored resources in the transmission process can be caused, so that the phenomena of blocking, frame loss, screen splash and the like of the monitored resources in the playing process can be caused, namely the use degree is reduced and the watching experience of the monitored resources is influenced. The availability information may indicate a possibility that the corresponding monitoring resource may be successfully downloaded and normally played, and the availability information may be indicated by a probability value or by a level, which is not limited in the embodiment of the present invention. Optionally, the availability information may be availability information corresponding to the current acquisition of the monitoring resource, or may be availability information of the historical acquired monitoring resource. When the availability information is the availability information corresponding to the obtained monitoring resource, the corresponding monitoring resource can be obtained first, and the corresponding availability information is determined, so as to ensure the real-time performance and the accuracy of the availability information. When the availability information is availability information corresponding to historically acquired monitoring resources, the availability information corresponding to the monitoring resources can be determined first, and when the monitoring information selected according to the availability information is received, the corresponding monitoring resources are acquired according to the monitoring information, so that the problem of network resource occupation possibly caused by acquiring multiple monitoring resources is avoided.

Optionally, the step 102 includes:

In the implementation of the present invention, when the availability information is the availability information corresponding to the currently acquired monitoring resource, the acquisition of the monitoring resource may be performed first, optionally, the second server may be a server for storing, maintaining, and managing the monitoring resource, such as a video network monitoring management server, and the first server may acquire the corresponding monitoring resource from the second server according to the monitoring information in the monitoring resource list. When the second server and the first server belong to networks with different protocols, a corresponding protocol conversion server can be added so as to monitor the successful transmission of the data of the resources. In addition, according to a mode of managing the monitoring resources by the second server, or in order to ensure stability and safety of the monitoring resources in the acquisition process, a link may be established with the second server for each monitoring resource in the monitoring resource list, and optionally, a link may be established through a socket, so as to implement end-to-end transmission of data of the monitoring resources.

In the embodiment of the present invention, optionally, when the first server obtains the monitoring resources from the second server, the first server may perform a predetermined number of request operations on each monitoring resource according to the link. The preset number can be determined according to the actual network condition or the user requirement, and can be any integer greater than or equal to 1, for example, the preset number is 1, 2, 3. The preset times corresponding to different monitoring resources can be the same or different. If the monitoring resource is successfully acquired before the request acquisition operation reaches the preset times, the acquisition of the monitoring resource can be stopped, and the request acquisition operation of the monitoring resource can be continuously executed until the preset times is reached so as to facilitate the statistical calculation.

In the embodiment of the present invention, in the process of acquiring the monitoring resources, the response time and the response times of successfully acquiring the first I frame image of each monitoring resource from the second server may be counted, where the I frame generally refers to the first frame in each Group of Pictures (GOP) in an MPEG (moving picture Experts Group) code. In MPEG coding, the picture frames in each group of pictures are divided into three types, I-frame, P-frame and B-frame, wherein I-frame is an intra-decoded frame, P-frame is a forward predicted frame, B-frame is a bidirectional interpolated frame, I-frame is a complete picture, and P-frame and B-frame record the change of the subsequent pictures relative to I-frame. Therefore, if the data of the I frame is lost and damaged, the monitoring video picture cannot display the black screen phenomenon, and the subsequent decoding of the P frame and the B frame cannot be carried out. In addition, each monitoring resource may have a plurality of picture groups, so that it is convenient to calculate the response time and the response times for successfully acquiring the first I-frame image of each monitoring resource, or the response time and the response times for successfully acquiring the I-frame images of all the picture groups of each monitoring resource, which is not limited in this embodiment of the present invention.

In this embodiment of the present invention, the response time may be a time interval from when the first server executes a monitoring resource request obtaining operation to the second server to when the first server successfully receives the first I frame image of the monitoring resource, or may be a time interval from when the first server receives a monitoring resource request sent by the terminal device to when the first server successfully receives the first I frame image of the monitoring resource, so that the response time can more truly reflect a delay from when the terminal device requests the monitoring resource to when the terminal device actually obtains the monitoring resource. Optionally, in order to avoid that the actual determination of the availability information of the monitoring resource is affected by too short or too long response time of a certain time, the response time may be an average value of response times corresponding to the past request obtaining operation and the current request obtaining operation of the monitoring resource, where the past request obtaining operation may be for monitoring resource requests sent by different terminal devices, or may be for only monitoring resource requests sent by the current terminal device.

In this embodiment of the present invention, the response times may be the number of times of success in acquiring the first I-frame image for the request acquisition operation of the monitoring resource request of this time, and for example, when the first server executes the request acquisition operation of the preset times 3 times to the second server for the monitoring resource, where the number of times of success is 2 and the number of times of failure is 1, the response times is 2, or after 1 time of failure and 1 time of success of the request, the request acquisition operation is stopped being executed, and the number of times of response is 1. Optionally, the response times may also be the total work times of the request obtaining operation of the monitoring resource request for all times of the monitoring resource and the request obtaining operation of the current monitoring resource request for the monitoring resource.

For example, the first server receives the monitoring resource request for the monitoring resource history and this time for 3 times in total, and the preset number of times of executing the request acquisition operation each time is 2. The request acquisition operation is executed according to the first monitoring resource request, wherein the operation is failed for the 1 st time and is successful for the 2 nd time; executing the request acquisition operation aiming at the second monitoring resource request, wherein the request acquisition operation is failed for the 1 st time and failed for the 2 nd time; and when the execution request acquisition operation is successful for the third monitoring resource request in the 1 st time, stopping executing the request acquisition operation. Therefore, the number of responses corresponding to the monitoring resource is 2.

Taking the time interval from when the response time is the monitoring resource request received from the first server and the first server successfully receives the first I frame image of the monitoring resource as an example, the response time of the 2 nd time is 100 milliseconds in the request acquisition operation executed for the first monitoring resource request; in performing the request acquisition operation for the third monitor resource request, the response time of the 1 st time is 50 milliseconds. Thus, the response time for this monitoring resource is 75 milliseconds.

In the embodiment of the invention, the response time and the response times are related to the playing quality of the monitored resources, so that the availability information of the monitored resources can be accurately judged according to the response time and the response times, so that a user can select proper monitored resources, and the working efficiency is improved.

In practical application, some monitoring resources have more request times and more response times, such as 10 requests and 5 responses; some monitoring resources have fewer requests and fewer responses, such as 5 requests and 3 responses. The number of responses of the first monitoring resource is greater than that of the second monitoring resource, but it can be seen that the probability of successful acquisition of the second monitoring resource is higher in an actual single request. Therefore, in order to avoid the influence of the above situation on the judgment of the availability information, the success rate of the response of obtaining the first I-frame image of each monitoring resource from the second server can be determined according to the response times. Optionally, the response success rate may be a ratio of the number of times of successfully obtaining the first I-frame image after the current preset number of times of request obtaining operations to the total number of times of request obtaining operations, or may also be a ratio of the number of times of successfully obtaining the first I-frame image to the total number of times of request obtaining operations, so as to obtain the response success rate.

For example, the first server receives the monitoring resource request for the monitoring resource history and this time for 3 times in total, and the preset number of times of executing the request acquisition operation each time is 2. The request acquisition operation is executed according to the first monitoring resource request, wherein the operation is failed for the 1 st time and is successful for the 2 nd time; executing the request acquisition operation aiming at the second monitoring resource request, wherein the request acquisition operation is failed for the 1 st time and failed for the 2 nd time; and when the execution request acquisition operation is successful for the third monitoring resource request in the 1 st time, stopping executing the request acquisition operation. At this time, the number of responses corresponding to the monitoring resource is 2, and the success rate of the responses is 40%.

In the embodiment of the invention, the availability of the monitoring resource can be divided into different grades according to different actual requirements, such as excellent, good, medium and poor, and different success rate intervals and response time intervals corresponding to different grades, such as response success rate of [ 90%, 80%), availability grade of excellent response time of (0,100] millisecond, response success rate of [ 80%, 60%), response time of (100, 200] millisecond and medium, and so on, and the corresponding availability grade is determined by matching the response success rate, the success rate intervals, the response time and the response time intervals to obtain corresponding availability information. Optionally, when the success rate interval matched with the response success rate of the monitoring resource and the response time interval matched with the response time are not in the same level, in order to ensure the accuracy of the availability information of the monitoring resource, a lower availability level may be selected as the availability information of the monitoring resource, so that the availability of the monitoring resource is greater than or equal to the availability level, and the accuracy of the availability information is ensured to the minimum.

In the embodiment of the invention, optionally, different grades can also correspond to different comprehensive scores of response time and response success rate. For example, the composite score [20,16) is excellent, [16,12) is excellent, [12,8) is good, [8,4) is medium, [4,0) is poor, etc.

Wherein, the composite score can be the sum, mean value, etc. of the response time score and the response success rate score. The response time scoring may be a result of scoring the response time according to a preset scoring mechanism, the preset scoring mechanism may correspond the scoring result to the response time interval, and determine a corresponding response time scoring according to the response time interval matched with the response time, or write a corresponding scoring algorithm, thereby scoring the response time. Response success rate scoring may be analogized. In addition, in practical application, for the monitoring resource, it can be considered that the shorter the response time is, the higher the response success rate is, the better the response success rate is, therefore, it can be determined that the shorter the response time is, the higher the response success rate is, the higher or lower the scoring result is, and the consistency between the scoring result and the availability of the monitoring resource is ensured. For example, the response time is rated as 10 in (0, 100) ms, 8 in (100, 200) ms, etc., the response success rate is rated as 10 in [ 100%, 90% >), and 9 in [ 90%, 80% >, etc., thereby comprehensively considering various parameters of the monitoring resources and further ensuring the accuracy of the availability information of the monitoring resources.

For example, the monitoring resource corresponds to a response success rate of 40% and a response time of 75 ms. At the moment, the success rate interval of the response success rate of 40% matching is more than or equal to 40% and less than or equal to 60%; the response time interval matching 75 ms is within 100 ms, which is excellent. The availability information corresponding to the monitoring resource may be determined as an availability level difference.

Or, the response success rate corresponding to the monitoring resource is 40%, and the response time is 75 milliseconds. At this time, the score of the response success rate corresponding to the response success rate of 40% is 4, the score of the response time corresponding to the response time of 75 milliseconds is 10, and the comprehensive score of the monitoring resource is 14, which corresponds to the available level, and so on. The availability information corresponding to the monitoring resource can be determined to be of a medium level.

Step 103: and sending the monitoring resource list and the availability information corresponding to each monitoring resource in the monitoring resource list to the terminal equipment.

In the embodiment of the present invention, after determining the availability information corresponding to each monitoring resource in each monitoring resource list, the monitoring resource list and the availability information may be sent to the terminal device, and optionally, each availability information may be sent after being attached to a row or a column of a corresponding monitoring resource in the monitoring resource list.

Optionally, after the step 101, the method further includes:

In the embodiment of the invention, after the corresponding monitoring resource list is obtained according to the monitoring resource request sent by the terminal equipment, the corresponding monitoring resource can be obtained according to the monitoring information stored in the monitoring resource list. The thumbnail corresponding to the monitoring resource can be generated according to the first I-frame image of the monitoring resource, and the thumbnail can reflect the general information of the monitoring resource, such as the monitoring environment, the monitoring object, and the like, because the thumbnail is generated according to the first I-frame image of the monitoring resource. In addition, because the I frame is a complete picture, and the subsequent P frame and B frame record changes relative to the I frame, the thumbnail generated by the first I frame image can also roughly reflect the monitoring content of the monitoring resource and reflect the definition of the monitoring resource to a certain extent, thereby helping a user obtain information of the monitoring resource except ID, name, location and the like, and facilitating the user to select a proper monitoring resource.

In the embodiment of the present invention, a first I frame of a monitoring resource in an h.264 format may be converted into a Picture in a jpg (Joint Photographic expert group) format as a thumbnail of the monitoring resource by ffmpeg (fast forwarding Moving Picture expert group). The Ffmpeg is a set of open source computer programs that can be used to record, convert digital audio, video, and convert them into streams. H.264 is a digital video compression format, and can obtain digital video streams with low code rate, high quality images, strong fault tolerance rate and strong network adaptability. A person skilled in the art may also convert the first I frame image of the monitoring resource in other ways to obtain a thumbnail corresponding to the monitoring resource, which is not limited in this embodiment of the present invention.

In the embodiment of the invention, after obtaining the thumbnails of different monitoring resources, the thumbnails can be sent to the terminal equipment which sends the monitoring resource request, and optionally, the thumbnails can be attached to the rows or columns corresponding to the monitoring resources in the monitoring resource list, so that a user can correspondingly view the monitoring resources and the thumbnails.

Referring to fig. 2, a flowchart illustrating steps of another embodiment of an information processing method according to the present invention is shown, and as shown in fig. 2, the method may be applied to a terminal device, and specifically may include the following steps:

step 201: a monitoring resource request is sent to a first server.

In the embodiment of the invention, the terminal equipment can send the corresponding monitoring resource request to the first server according to the input of the user. The input of the user may be that the user inputs or selects a name, a coordinate, a serial number, and the like of a geographical location that the user wants to view monitoring, or the user selects a corresponding geographical location on a map displayed by the terminal device, and then the terminal device sends a monitoring resource request for monitoring resources in the geographical location to the first server according to the input.

For example, the terminal device receives the geographical location name of the "beijing haichi district" input by the user, and sends a monitoring resource request aiming at the "beijing haichi district" to the first server.

Step 202: and receiving a monitoring resource list returned by the first server aiming at the monitoring resource request and availability information corresponding to each monitoring resource in the monitoring resource list.

In the embodiment of the present invention, the monitoring resource list returned for the monitoring resource request includes monitoring information corresponding to the monitoring resource request, that is, all monitoring information included in the geographic location input by the user, and the availability information corresponding to each monitoring resource is counted by the first server in the process of acquiring the monitoring resource according to the monitoring resource list in the monitoring resource list.

Step 203: and displaying the availability information corresponding to each monitoring resource in the monitoring resource list in a display interface of the monitoring resource list.

In the embodiment of the present invention, the terminal device may display the monitoring list in the display interface, and optionally, may display the monitoring information in the monitoring resource list and the availability information corresponding to the monitoring resource in the same display interface, for example, display the availability information in a row or a column of the corresponding monitoring information. The terminal device may determine to play the corresponding monitoring resource according to a selection operation of the user for the monitoring resource list. At this time, the user can refer to the availability information and select a proper monitoring resource for playing and viewing.

Optionally, after the step 201, the method further includes:

In the embodiment of the present invention, the terminal device may further receive a thumbnail corresponding to the monitoring resource returned by the first server, and display the thumbnail on a display interface of the monitoring resource list, optionally, the thumbnail may be displayed in a single column or in double columns, and further, corresponding monitoring information and availability information may be displayed on the back side by turning over the thumbnail according to the display of the thumbnail by the user.

In the embodiment of the invention, for the monitoring resource request of the terminal equipment, the first server can determine the corresponding monitoring resource list, and determine the availability information corresponding to each monitoring resource in the monitoring resource list by traversing the monitoring resource list, and finally send the monitoring resource list and the availability information corresponding to each monitoring resource in the monitoring resource list to the terminal equipment for identification, so that when a user checks monitoring through the terminal equipment, the user can obtain the available information of the monitoring resources besides the original monitoring information such as the name, the serial number, the position, the responsible person and the like of the monitoring resources from the monitoring resource list, and the user can select the monitoring resources corresponding to the available information according to the requirement, thereby improving the efficiency of calling and checking the monitoring resources.

2. Video networking packet definition

2.1 Access network packet definition

The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.

As shown in the following table, the data packet of the access network mainly includes the following parts:

DA

SA

Reserved

Payload

CRC

wherein:

the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;

the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);

the reserved byte consists of 2 bytes;

the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;

the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.

2.2 metropolitan area network packet definition

The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.

In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.

As shown in the following table, the data packet of the metro network mainly includes the following parts:

DA

SA

Reserved

label (R)

Payload

CRC

Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
