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 application: 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.

Based on the characteristics of the video network, the embodiment of the application provides one of core concepts for solving the technical problems, the client sends a target data acquisition instruction which accords with a video network transparent transmission protocol, the video network server sends the target data acquisition instruction to the service terminal, then the service terminal can start the intelligent acquisition equipment to acquire target data according to a data object information and a data format information in the target data acquisition instruction, and the service terminal packs the target data into video network data and sends the video network data to the client. The technical purpose that the user can acquire the target data acquired by the intelligent acquisition equipment in the video network is achieved.

Example one

Referring to fig. 5, a flowchart illustrating a first step of a data acquisition method applied to a video network according to an embodiment of the present application is shown, where the video network includes a client, a video network server in communication connection with the client, and a service terminal in communication connection with the video network server, the service terminal is connected with an intelligent acquisition device, and the service terminal is configured with a plurality of driving interfaces.

Among them, the client may be, but is not limited to, the following devices: personal Computers (PCs), smart phones, tablet computers, televisions, and the like. The service terminal can be a microcomputer, and the intelligent acquisition device can be, but is not limited to, the following devices: high-speed shooting instrument, scanner. In the embodiment of the application, the service terminal can be connected with the intelligent acquisition equipment to form an integrated device, for example, the service terminal and the intelligent acquisition equipment form an integrated machine.

In this embodiment of the present application, the driving interface may be understood as a software interface in the service terminal, where the software interface is used to drive each data acquisition interface in the intelligent acquisition device, and the data acquisition interface of the intelligent acquisition device may be connected to a hardware device configured on the intelligent acquisition device, and in practice, the data acquisition interface may include, but is not limited to, a camera interface, a USB interface, a bluetooth interface, and the like. The service terminal can trigger the data acquisition interface of the intelligent acquisition equipment by starting the corresponding driving interface, and further awaken the corresponding hardware equipment, and in practice, different driving interfaces can drive different data acquisition interfaces of the intelligent acquisition equipment so as to acquire target data in different formats.

The method in the embodiment of the application may specifically include the following steps:

step 501, the video network server receives a target data acquisition instruction which is sent by the client and accords with a video network transparent transmission protocol, and sends the target data acquisition instruction to the service terminal based on the video network transparent transmission protocol.

In the embodiment of the application, the client and the service terminal can be registered in the video networking server in advance, and can join the video networking after the registration is successful. In practice, the target data obtaining instruction may be generated by the client when receiving an operation of obtaining the target data from the user, or may be generated by the client when a certain service is triggered, for example, the client detects that a service for changing the contact is triggered.

In the embodiment of the application, the target data acquisition instruction is an instruction according with a video networking transparent transmission protocol, the video networking transparent transmission protocol is one of a plurality of video networking protocols, the video networking transparent transmission protocol can be a protocol for unidirectional transmission of the instruction, the target data instruction encapsulated by the video networking transparent transmission protocol is unidirectional transmission in the video networking, and when the service terminal receives the target data acquisition instruction, whether to reply or not can be determined by self according to the content of the target data acquisition instruction, namely the service terminal can not send a reply signaling to the client according to the target data acquisition instruction. Therefore, the signaling frequency between the client and the service terminal can be reduced, the forwarding burden of the video network server and the instruction processing and analyzing burden of the client and the service terminal are reduced, and partial memories of the client and the service terminal are released.

In practice, the video network server may not analyze the payload data in the target data acquisition instruction, but directly send the target data acquisition instruction to the service terminal according to the protocol packet header in the target data acquisition instruction, and the service terminal analyzes the payload data in the target data acquisition instruction after receiving the target data acquisition instruction. Therefore, when the video networking transparent transmission protocol is adopted, the video networking server can not analyze the payload data therein, so that the transmission confidentiality of the target data acquisition instruction is improved, and the instruction is prevented from being intercepted.

In this embodiment of the present application, the payload data may refer to data information carried in the target data obtaining instruction, and may include, but is not limited to, the following information: target data object information, target data format information, time information, port information, intelligent acquisition device information, and the like.

Step 502, the service terminal analyzes the data format information and the data object information from the target data acquisition instruction.

In the embodiment of the application, after receiving the target data acquisition instruction, the service terminal may analyze the data object information and the data format information from the target data acquisition instruction by using the video networking transparent transmission protocol. The data object information may refer to information of an object of target data to be captured, and the object may include a certificate, a stereoscopic model, a photograph, and the like. The data format information may refer to a format of the acquired target data, and may include a picture format, a PDF format, a video format, and the like. In specific implementation, the service terminal can also display the data object information, so that a user can determine a target object to be acquired according to the displayed data object information.

Step 503, the service terminal determines a data acquisition mode corresponding to the data object information, and starts a first driving interface corresponding to the data format information.

In practice, after the service terminal analyzes the data object information and the data format information, the service terminal may determine a corresponding data acquisition mode according to the data object information, and start the corresponding first driving interface according to the data format information. The data acquisition mode may be an acquisition mode adopted when acquiring the target data, and if the data object information indicates that the data object to be acquired is an identity card, the data acquisition mode may be determined as an identity card scanning mode. In specific implementation, a plurality of data acquisition threads can be set in the service terminal, and each data acquisition thread corresponds to one data acquisition mode.

Step 504, the intelligent acquisition device acquires target data of a target object according to the data acquisition mode based on the started first driving interface.

In practice, the intelligent acquisition device may trigger the target data acquisition interface in communication connection with the first driving interface based on the started first driving interface, and the triggered target data acquisition interface may wake up a hardware device connected to the intelligent acquisition device itself, and the woken up hardware device may be configured to acquire target data of the target object according to the data acquisition mode. When the first driving interface is driven, the intelligent acquisition device correspondingly triggers the target data acquisition interface connected with the first driving interface, the triggered target data acquisition interface can further awaken the corresponding hardware device, and the hardware device can acquire the target data of the target object according to the data acquisition mode. During specific implementation, a user can place a target object into the intelligent acquisition equipment according to the displayed data object information, and further the intelligent acquisition equipment can acquire target data of the target object.

For example, taking data object information as information representing that an object to be acquired is an identity card, taking data format information as information in a picture format as an example, a data acquisition mode determined by a service terminal is an identity card acquisition mode, the identity card acquisition mode corresponds to an identity card data acquisition thread, an intelligent acquisition device triggers a picture data acquisition interface of the intelligent acquisition device based on a started first driving interface, and further starts a camera configured by the intelligent acquisition device, and the camera automatically adjusts a focal length and a shooting range of a lens of the camera under the operation of the identity card data acquisition thread to adapt to shooting requirements of the identity card, and further acquires a picture of the identity card, wherein the specific format of the picture can be a JPG format, a JFPG format, and the like, and the embodiment of the application is not limited herein.

And 505, the service terminal acquires the target data, packages the target data into video networking data conforming to a video networking protocol, and sends the video networking data to the video networking server.

In practice, the service terminal can automatically acquire target data acquired by the intelligent acquisition equipment through a communication data line connected with the intelligent acquisition equipment, add a video networking protocol packet header to the target data, further obtain video networking data conforming to a video networking protocol, and send the video networking data to a video networking server. In the embodiment of the application, the video networking data is data conforming to a video networking protocol, and the video networking protocol may be different from a video networking transparent transmission protocol. In this way, the video network server can analyze the target data when receiving the video network data, so that the storage and backup operations of the target data can be performed.

Step 506, the video network server sends the video network data to the client.

In this embodiment, the video networking server may send the video networking data to the client according to the address of the client recorded in the protocol packet header of the video networking data. Further, the client acquires target data of a target object required by the client.

In the embodiment of the application, a target data acquisition instruction which accords with the video networking transparent transmission protocol is sent by a client, and then the service terminal can determine a corresponding data acquisition mode and start a corresponding first driving interface according to data object information and data format information in the target data acquisition instruction, so that the intelligent acquisition equipment can trigger the target data acquisition interface to acquire target data of a target object according to the data acquisition mode based on the started first driving interface, and the target data is packaged into video networking data through the service terminal and returns to the client through a video networking server. Furthermore, the target data of the target object, which accord with the specified data format, is acquired through the first driving interface, and in the acquisition process, the data acquisition mode is flexibly adjusted according to the target object represented by the data object information, so that the matching degree of the acquired target data and the target object can be improved. Therefore, the data of other formats besides the audio and video data acquired by the intelligent acquisition equipment can be acquired in the video network, the service application field of the video network is widened, and the problem that data such as photos or scanned files acquired by some acquisition equipment cannot be acquired in the video network in the past is solved.

Referring to fig. 6, a flowchart illustrating steps of a further data acquisition method applied to a video network according to an embodiment of the present application is provided, where the video network includes a client, a video network server in communication connection with the client, and a service terminal in communication connection with the video network server, the service terminal is connected with an intelligent acquisition device, and the service terminal is configured with a plurality of driving interfaces.

Among them, the client may be, but is not limited to, the following devices: personal Computers (PCs), smart phones, tablet computers, televisions, and the like. The service terminal can be a microcomputer, and the intelligent acquisition device can be, but is not limited to, the following devices: high-speed shooting instrument, scanner. In the embodiment of the application, the service terminal can be connected with the intelligent acquisition equipment in a USB mode to form an integral device, and for example, the service terminal and the intelligent acquisition equipment form an integrated machine.

The method specifically comprises the following steps:

step 601, the client generates a target data acquisition instruction conforming to the video networking transparent transmission protocol.

In an application scenario in which a client generates a target data acquisition instruction in the embodiment of the application, the client may be provided with a function interface for providing a user with a selection operation, and the function interface may include multiple selections of data objects, for example, a selection of data objects such as "acquire an id card photo" and "acquire a certificate photo", and after the user selects "acquire an id card photo", the function interface may further display a selection of a data format of the data object, for example, a selection of "PDF format" or "picture format". And the client can generate a corresponding target data acquisition instruction according to the selection of the user.

In another application scenario in which the client generates the target data acquisition instruction in the embodiment of the application, the client may be a client server, and may provide background service and audit for handling various services, for example, provide background service and audit for a reserved information change service of a policy, a mobile phone loss report service, and the like. When a user sends a corresponding service transaction application to a client, the client can automatically generate a target data acquisition instruction according to the type of service transaction to be applied. If the service type of the application is a loss report service type of the mobile phone, the target data acquisition instruction may include data object information and data format information that need to be acquired in the process of handling the loss report of the mobile phone.

Step 602, the video network server receives a target data acquisition instruction which is sent by the client and conforms to a video network transparent transmission protocol, and sends the target data acquisition instruction to the service terminal based on the video network transparent transmission protocol.

In practice, the client sends the generated target data acquisition instruction to the video network server, and the video network server in turn sends the target data acquisition instruction to the service terminal.

As an optional example of the embodiment of the present application, the step of sending the target data obtaining instruction to the service terminal by the video network server in step 602 specifically includes the following sub-steps:

sub-step 6021, the video network server removes the first MAC address and the first device number from the target data acquisition instruction, and acquires the second MAC address and the second device number of the client.

In this embodiment of the application, the target data obtaining instruction is an instruction conforming to a video networking transparent transmission protocol, and a protocol header of the target data instruction may include a first MAC address and a first device number of a service terminal, so that, after obtaining the target data obtaining instruction, the video networking server may remove the first MAC address and the first device number in a protocol header of the target data obtaining instruction based on the video networking transparent transmission protocol, and obtain a second MAC address and a second device number of the client.

In specific implementation, because the client is registered in the video network server in advance, the video network server can store the information such as the MAC address, the device number, the device name and the like of the client, and the target data acquisition instruction can only include the device name of the client, so that the video network server can search the MAC address and the device number of the client from the information stored in the video network server according to the device name of the client.

Sub-step 6022, the video network server writes the second MAC address and the second device number into the protocol header of the target data acquisition instruction.

When the video network server acquires the second MAC address and the second device number of the client, the second MAC address and the second device number of the client may be encapsulated in the protocol packet header of the target data acquisition instruction.

And a substep 6023, sending the target data acquisition instruction written with the second MAC address and the second device number to the service terminal by the video network server.

In practice, after writing the second MAC address and the second device number, the video network server may send the target data obtaining instruction to the service terminal, so that when the service terminal receives the target data obtaining instruction, the address of the service terminal may be determined according to the second MAC address and the second device number recorded in the protocol packet header, so as to subsequently send the acquired target data to the service terminal.

Step 603, the service terminal analyzes the data format information and the data object information from the target data acquisition instruction.

In the embodiment of the application, after receiving the target data acquisition instruction, the service terminal may analyze the target data acquisition instruction by using a video networking protocol, so as to obtain a protocol packet header and payload data in the target data acquisition instruction, and may record a second MAC address in the protocol packet header and the second device number, where the payload data may include data object information and data format information.

For example, taking the above application scenario as an example, when the client performs an operation of "acquiring a certificate photo" and selecting a "picture format" according to the user, in the generated target data acquisition instruction, the data object information may be the "certificate photo", and the data format information may be the "picture format".

For example, when the client receives a request for a loss report service of a mobile phone, in the generated target data acquisition instruction, the data object information may be an "identification card photo" or a "driver card photo", and the data object information may be in a "picture format".

Step 604, the service terminal determines a data acquisition mode corresponding to the data object information, and starts a first driving interface corresponding to the data format information.

In the embodiment of the application, when the data acquisition mode is determined according to the data object information, the data acquisition threads corresponding to the data object information can be operated in the preset data acquisition threads, and the operated data acquisition threads can support the acquisition of target data according to the determined data acquisition mode. If the data object information is the 'certificate photo', the certificate acquisition thread can be started, if the data object information is the 'driver license photo', the driver license photo acquisition thread can be started, and if the data object information is the 'declaration file', the declaration file acquisition thread can be started.

As an embodiment of the present application, the data format information is text format information, video format information, or picture format information, and specifically, in this step 604, if the data format information is text format information, the service terminal may start a second driving interface corresponding to the text format information. In practice, the second driving interface may be a software interface for driving a text data acquisition interface in the smart acquisition device.

If the data format information is the video format information, the service terminal may start a third driving interface corresponding to the video format information. In practice, the third driving interface may be a software interface for driving the video data acquisition interface in the intelligent acquisition device.

If the data format information is the picture format information, the service terminal may start a fourth driving interface corresponding to the picture format information. In practice, the fourth driving interface may be a software interface for driving the picture data collecting interface in the intelligent collecting device.

It should be noted that the second driving interface, the third driving interface, and the fourth driving interface in this embodiment are driving interfaces under different data format information, that is, in the case of text format information, the first driving interface is the second driving interface, in the case of video format information, the first driving interface is the third driving interface, and in the case of picture format information, the first driving interface is the fourth driving interface.

Step 605, the intelligent acquisition device acquires target data of a target object according to the data acquisition mode based on the started first driving interface.

In practice, when the service terminal starts the first driving interface, the corresponding target data acquisition interface in the intelligent acquisition device is driven, and then the hardware device connected with the data acquisition interface is awakened, and the driven hardware device acquires target data of a target object according to a data acquisition mode.

In specific implementation, if the data object information is a 'declaration file' (a target object is a declaration file) and the data format information is text format information, the determined data acquisition mode is a file acquisition mode, a declaration file acquisition thread is correspondingly started, the started first driving interface is a second driving interface corresponding to the text format information, correspondingly, the text data acquisition interface of the intelligent acquisition equipment is started, and then a USB connected with the text data acquisition interface is started, the started USB can read the declaration file under the operation of the declaration file acquisition thread, and specifically, a user can connect a storage device storing the declaration file to the USB by using an existing data line so as to transmit the declaration file to the USB.

If the data object information is a 'driver license photo' (the target object is a driver license), and the data format information is video format information, the determined data acquisition mode is a driver license acquisition mode, a driver license acquisition thread is started, and the started first driving interface is a third driving interface, so that the video data acquisition interface in the intelligent acquisition equipment is started, and then the camera is awakened, and the awakened camera shoots the driver license under the operation of the driver license acquisition thread to acquire the video data of the driver license.

If the data object information is a certificate photo (a target object is a certificate) and the data format information is picture format information, the determined data acquisition mode is a certificate photo acquisition mode, a corresponding started certificate acquisition thread, and the started first driving interface is a fourth driving interface corresponding to the picture format information.

If the data object information is a 'mold' (a target object is a mold) and the data format information is video format information, the determined data acquisition mode is a mold acquisition mode, a corresponding started mold acquisition thread is provided, the started first driving interface is a third driving interface corresponding to the video format information, correspondingly, a video data acquisition interface in the intelligent acquisition equipment is started, and then a camera is awakened, and the awakened camera shoots the mold from four directions of top, bottom, left and right under the operation of the mold acquisition thread so as to acquire the video data of the mold.

And 606, the service terminal acquires the target data, packages the target data into video networking data conforming to a video networking protocol, and sends the video networking data to the video networking server.

In this embodiment of the application, the process of the service terminal encapsulating the collected target data into the video networking data of the video networking protocol may be:

and the service terminal adds a video networking protocol packet header to the target data, wherein the networking protocol packet header comprises the first MAC address, the first equipment number, the second MAC address and the second equipment number.

The first MAC address and the first equipment number are the MAC address and the equipment number of the service terminal, and the second MAC address and the second equipment number are the MAC address and the equipment number of the client. Thus, the protocol header of the video networking packet includes the address of the source device (service terminal) and the address of the destination device (client).

Step 607, the server sends the data to the client.

In this embodiment of the present application, since the video networking data is data conforming to a video networking protocol, and the video networking data includes an address of a source device (service terminal) and an address of a destination device (client), the video networking server may not process a protocol packet header of a video networking data packet, so as to directly forward the video networking data to the client. Thus, when the video networking data is transmitted through the video networking protocol, the client can return the state of receiving the video networking data to the service terminal, for example, when the target data is data in a video format, the target data can be firstly packaged into data of a real-time data transmission RTP protocol, and then the RTP data is packaged by adopting the video networking protocol, so that the client confirms the receiving state of the video networking data to the service terminal in real time.

As an optional example of the embodiment of the present application, after the step of acquiring the target data in step 606, the following steps may be further included:

at step s1, the service terminal determines whether the target data matches the data format information.

In practice, due to reasons such as poisoning of a service terminal, the first driving interface of the driver is an incorrect driving interface, which causes starting of an incorrect hardware device, and thus, a format of target data of a target object acquired by the incorrect hardware device may be inconsistent with data format information, for example, the data format information is video format information, but the first driving interface of the driver is determined to be the fourth driving interface (for text), and a format of the target data acquired in this way is also a picture format, instead of a video format. In order to discriminate such a situation, after the service terminal acquires the target data, it may determine whether the format of the target data matches the data format information, specifically, if the data object information is video format information, it determines whether the format of the target data is a video format, for example, the format of the target data is MP4 format, and is a video format, it may be determined that the target data matches the data format information, and if the format of the target data is JPG format, it is not a video format, it may be determined that the target data does not match the data format information.

In step s1, if it is determined that the target data matches the data format information, the service terminal performs an operation of encapsulating the target data into the internet-of-view data and a subsequent operation of sending the internet-of-view data to the internet-of-view server. If it is determined that the target data does not match the data format information, the service terminal proceeds to step s 2.

Step s2, the service terminal generates error information including the data object information and displays the error information.

In practice, when the service terminal determines that the format of the target data is inconsistent with the data format information, the service terminal may generate error information, where the error information may include data object information, so that a user may know, according to the error information, which type of target object has an error in data acquisition, so as to provide a solution in a targeted manner. Wherein the error information may be code information, for example, 40021#, and the error information may be displayed on the display device.

Through the step s1 and the step s2, the service terminal has the function of intelligently identifying whether the target data is the required data, and the acquisition accuracy of the target data is enhanced.

At step 608, the client displays or stores the received video networking data.

In the embodiment of the application, the client can display the video networking data and can also store the video networking data.
