(8) and a left indicator light of the network cable on the WAN port link is on to indicate that the network port is normal.

Further, the server runs a Linux system, and the video streaming media server program is a Live555 server program.

Specifically, the Live555 server program provides the RTSP video protocol service with the format of.264.

Specifically, the RTSP video protocol has port numbers 554 and 8554, where the 554 port requires administrator privileges.

Further, the server also runs a gSOAP program and a video monitoring client conforming to ONVIF standard, wherein the gSOAP program reads a WSDL file in ONVIF protocol and calls and runs at least one of the following functions: and a device discovery service function and a device service entry function are adopted, so that the video monitoring client can receive the RTSP video stream sent by the NVR camera.

Specifically, the frame buffer size of the server is set to 150000K.

In particular, the ONVIF specification describes a model, interfaces, data types, and modes of data interaction for network video. And some existing standards, such as WS series standards, are reused. The ONVIF specification aims to implement a network video framework protocol, so that network video products (including video recording front ends, video recording equipment and the like) produced by different manufacturers are completely communicated.

The interfaces defined by the device management and control section of the ONVIF specification are all provided in the form of Web Services. The ONVIF specification covers the full XML and WSDL definitions. Each terminal device supporting the ONVIF specification must provide a Web Service corresponding to the function. And the data interaction between the server and the client adopts a SOAP protocol. Other parts of the ONVIF, such as audio video streaming, are done through RTP/RTSP.

SOAP is an abbreviation of Simple Object Access Protocol. SOAP provides a standard way for applications running on different operating systems and using different technologies and programming languages to communicate with each other. Is a protocol based on XML. A SOAP message is a generic XML document containing the following elements:

the required Envelope element can mark the XML document as a SOAP message;

an optional Header element containing Header information;

the necessary Body element, which contains all call and response information;

an optional Fault element that provides information about the sheath error that occurred during the processing of the message.

In the SOAP request sent to the Web Service, the fields in the Body element need to conform to the data types in WSDL. In the process of constructing the SOAP, the corresponding relation must be acquired from the WSDL file and mapped. However, such a corresponding process would be repetitive and mechanical, and a compilation tool named gSOAP should be developed to avoid unnecessary human errors and save development time.

The gSOAP compiling tool provides SOAP/XML implementation about C/C + + language, so that the work of developing web services or client programs by C/C + + language is much easier. The contents related to the implementation details of the development-independent SOAP protocol are hidden from the developer. Because SOAP provides a standardized approach, the compiler of gSOAP can automatically translate user-defined localized C or 0+ data types into XML-syntax-compliant data structures, thus freeing the user from SOAP detail implementation by using only a simple set of APIs, and can concentrate on the implementation of application logic. And the code framework for developing the SOAP communication protocol aspect of the Web Services can be generated by using gSOAP across a plurality of operating systems, language environments and different groups behind the firewall, and developers only need to realize the called function of the server and then can call the function at the far end like calling the local function at the client end. gSOAP contains two tools, wsdl2h and soapcpp2, to generate a code frame.

Specifically, refer to the data flow diagram of video transmission using ONVIF standard shown in fig. 4; the ONVIF standard includes three types of devices, which are a central management unit CMU, such as a management center in the drawing, a monitoring front-end unit PU, such as an NVR camera in the drawing, and a monitoring client-end unit CU of a monitoring system, such as a server in the drawing, and the communication flows are as follows:

1. and after the device is on line, sending a HELLO message to the CMU.

And 2, when the CMU needs to search the equipment, sending a PROBE message to the PU.

And 3, carrying out signaling interaction between the CMU and the PU, requesting a capability set, and acquiring configuration.

And 4, enabling the CU to be on line, registering with the CMU, and establishing connection.

And 5, signaling interaction is carried out between the CMU and the CU, and the device list is transmitted.

6. Under the coordination of the CMU, the CU and the PU establish connection to transmit code streams.

The ONVIF standard has the advantages that the interaction mode of the PU and the CMU is changed, and the CMU is not connected with the PU for a long time any more; following the ONVIF specification, there is a unified standard for signaling and message content.

The ONVIF specification introduces the concept of Web Service to video surveillance. The actual functions of the equipment are abstracted to the Service of Web Service, the control unit of the video monitoring system appears in the form of the identity of the client, and the control operation is completed in the form of Web request.

The ONVIF specification can bring the advantages to a video monitoring system

(1) The interface of the function is abstracted. The configuration of the devices and the manner of operation are unified.

(2) The control end is not concerned with the model of the equipment, but the Web Service provided by the equipment regulates the behavior out of the range of the Web Service in the video system.

(3) ONVIF provides WSDL of each module, and has a development mode with high efficiency.

Referring to fig. 5, a flowchart of a third embodiment of the all-in-one door access control machine with NVR provided by the present application includes the following steps:

s301) creating a development environment;

s302) reading the WSDL file of the ONVIF through gSOAP to generate a code frame;

s303) carrying out RTSP video docking;

s304) operating a live555MediaServer server;

s305) starting the Onvif Device Manager test.

Here, WSDL refers to Web service Description Language (Web Services Description Language). WSDL is a document written using XML. Such a document may describe a certain Web service. It may specify the location of the service, and the operation (or method) provided by the service.

Specifically, a WSDL file of ONVIF is read through gSOAP, and a generated code frame, as shown in fig. 7, is generated by an NVR all-in-one gate inhibition machine using a gSOAP tool, and the code frame is composed of some files required by automatic generation of remote calls.

In addition, some ONVIF interfaces need to carry authentication information when calling, and need to use the soap _ wsse _ add _ usernamentokendigest function for authorization, so that a # import "wsse.h" needs to be added at the beginning of an onvif.h header file, otherwise, compilation will be wrong.

The commands are as follows:

# Access onvif directory

cd gsoap-2.8/gsoap/samples/onvif

File # Modify onvif.h, add # import "wsse.h" at the beginning "

vi onvif.h。

Referring to the HTTP digest authentication flowchart shown in fig. 9 and the device authentication flowchart of the Onvif protocol shown in fig. 10, an authentication flow of digest includes the following processes:

1. the client wishes to fetch a resource on the server and sends a Get request to the server.

2. After receiving the request from the client, the server finds that the resource needs authentication information, determines whether the request message has an Authorization header, and returns a message 401(Unauthorized) to the client if the request message does not have the Authorization header. In this 401 reply, the server will add a WWW-Autothenate header at the same time

3. After receiving the server's 401(Unauthorized) reply, the client uses the nonce value in the server reply message, plus username, password, http method, http uri, and uses MD5 (or other algorithm specified by the server) to calculate the request-digest as the value of the repson header field. And resend the request;

4. after receiving the request sent by the client, the server finds out the password of the user according to the username, and calculates the request-digest (response) by the same method as the client. And then comparing with the received request-digest, if the request-digest is consistent with the received request-digest, successfully verifying, receiving the request of the client, and successfully returning a result. With an Authentication-Info header. The client side carries out server authentication according to the parameters in the message header.

The authentication process of the Onvif initialization equipment is as follows:

1. the client obtains the time through the GetSystemDateAndTime

2. The client and server perform a time comparison and, if necessary, a time synchronization. If the time difference between the client and server is too great, the server may reject WS _ UsenameToken, at which point the NTP or setSystemDateAndTime command may be used for time synchronization

3. The client checks to see whether the server has a registered user, and if no user exists, a user is newly built and authenticated.

User management:

creating a user:

the creating user needs to provide 3 parameters:

1.name:

2,password

userlevel for setting user rights

The client creates users and sets the parameters by using CreateUsers commands; after successful creation, the device can be authenticated using an authentication procedure like HTTP digest. The authentication process has two request-response interactions: the first time is abstract inquiry, the server returns an authentication message header to request the terminal to do message abstract. In the second interaction, the client has an authentication message header in the request, which contains abstract information and other parameters, the server authenticates the client after receiving the authentication message header, and sends back a response after the authentication is successful, and the server has the authentication message header. The client side carries out server authentication according to the parameters in the message header.

Specifically, referring to the flowchart of the fourth embodiment of the all-in-one entry control machine with NVR shown in fig. 6, the step S303RTSP video docking further includes the following sub-steps:

s3031) the management center CMU discovers the equipment;

s3032) after the device discovery is successful, the monitoring front end unit PU sends requests for acquiring a device end capability set and the like;

s3033) the monitoring front end unit PU sends and obtains audio and video source information and audio and video coding and decoding information;

s3034) the monitoring front end unit PU sends and acquires the stream media URL information.

Wherein, the server of live5555MediaServer is operated to complete the RTSP function.

Specifically, default ports for RTSP are also modified to 554 and 8554, and the default is to try to use the port 554 first and unsuccessfully reuse the port 8554. When the live555MediaServer program is run on the Linux server, the sudo or root authority user can open 554 the port. Otherwise, the 8554 port is opened.

Referring to fig. 8, a flowchart of a data transmission method of an all-in-one gate inhibition machine with NVR provided by the present application includes the following steps:

s100) connecting an access control mainboard with an identity recognition module, an NVR camera, a router and a management platform with a server in an internet mode;

s200) acquiring video and image information, and performing data transmission by using an RTSP (real time streaming protocol) transmission protocol through a router after encoding;

s300) discovering the camera device by using an ONVIF standard, transmitting video and image data through a router and storing the video and image data in a server;

s400) displaying the video and the image data on a display device.
