s3, generating a national standard code of a virtual national standard protocol according to the identification information;

s4, binding identification information and national standard codes;

s5, taking national standard codes as identifiers of the camera equipment, and registering the camera equipment to a superior monitoring platform through a GB28181 protocol;

and S6, performing data interaction between the camera equipment and a superior monitoring platform based on an ONVIF protocol and a GB28181 protocol.

In this embodiment, the method for converting the ONVIF device to the GB28181 device may be applied to the system shown in fig. 2. Referring to fig. 2, steps S1 to S6 may be performed by a collaboration server provided between the camera device and the upper monitoring platform.

In this embodiment, when step S1 is executed, that is, the step of adding the camera device supporting the ONVIF protocol is executed, the following steps may be specifically executed:

s101, adding camera equipment through an equipment searching function of an ONVIF protocol;

or alternatively

S102, reading a table in a csv format; the table contains the device IP, the device port, the device account, and the device password of the camera device;

and S103, traversing the content in the table, and adding the camera equipment.

Step S101 is a step of automatically adding a camera apparatus, and steps S102 to S103 are steps of manually adding a camera apparatus.

In steps S102-S103, the functions of the rows and columns of the table may be implemented in a format similar to csv. The table contains four columns representing device IP, device port, device account, and device password, respectively, and then each row represents a device. When the server reads the table, the camera equipment is manually added in a traversing mode.

In this embodiment, when step S2, that is, the step of acquiring the identification information of the camera device, is executed, the following steps may be specifically executed:

s201, acquiring an equipment IP and an equipment port of camera equipment;

and S202, forming identification information of the camera equipment by using the equipment IP and the equipment port.

By performing steps S201-S202, the obtained device IP and device port (port) can be identified by IP: and the port form forms unique identification information of the camera equipment.

In this embodiment, when step S3, that is, the step of binding the identification information and the national standard code, is executed, the following steps may be specifically executed:

s301, setting a data table in a database;

and S302, recording the identification information and the national standard codes in a data table.

The national standard code is specified in gbt28181.P83 (GB 28181 protocol), "coding rule a is composed of 20 decimal numeric characters consisting of four code segments of central code (8 bits), industry code (2 bits), type code (3 bits), network identifier (1 bit), and serial number (6 bits), i.e., system code = central code + industry code + type code + network identifier + serial number. "outside the 6-bit serial number, other 13-bit national standards are specified in detail, so that one hundred thousand serial numbers are available for user-defined, at this time, a table can exist in the database of the server, two columns of the table are respectively the device unique identifier and the virtual national standard code, and the method is similar to the method of' 192.168.1.2:34567< - >44010600491327000001 "to bind the unique identifier and the national standard number, wherein the serial number of the last 6 bits can be increased by itself according to the order of adding the equipment.

In this embodiment, when step S6 is executed, that is, a step of performing data interaction based on the ONVIF protocol and the GB28181 protocol between the camera device and the upper monitoring platform is executed, the following steps may be specifically executed:

S601A, when the upper-level monitoring platform needs key broadcasting, pulling an audio and video stream from camera equipment through an ONVIF;

S602A, converting the audio and video stream into a format supported by a GB28181 protocol;

and S603A, sending the audio and video stream to a superior monitoring platform.

In this embodiment, steps S601A to S603A are the first execution manner of step S6. Referring to fig. 3, when step S601A is executed, the ONVIF uses an RTSP protocol to pull an audio/video stream, and the RTSP uses an RTP to encapsulate an audio/video protocol, for example, the video protocol H264 of the main stream of the camera is encapsulated by RFC 6184. However, GB28181 has a specified audio-video encapsulation protocol, in which H264 is encapsulated into PES and then encapsulated into PS and then RTP is transmitted, i.e. ISO/IEC 13818-1:2000, the original audio and video streams, such as H264 and AAC, can be analyzed from the audio and video stream of ONVIF according to RFC6184, and then encapsulated into RTP packets supported by GB28181 according to ISO/IEC 13818-1 for push.

By executing steps S601A-S603A, the compatibility between the camera device using the ONVIF protocol and the upper monitoring platform using the GB28181 protocol can be achieved, and even if the camera device using different protocols and the upper monitoring platform are used, the data can be transmitted and received, and the on-demand function of the upper monitoring platform is achieved, which is equivalent to converting the camera device using the ONVIF protocol into the camera device using the GB28181 protocol without replacing hardware of the camera device.

In this embodiment, when step S6 is executed, that is, when data interaction based on the ONVIF protocol and the GB28181 protocol is performed between the camera device and the upper monitoring platform, the following steps may be specifically executed:

S601B, when the upper-level monitoring platform needs PTZ control, obtaining a PTZ instruction of GB28181 from the upper-level monitoring platform;

S602B, converting the PTZ instruction of GB28181 into a PTZ instruction of ONVIF;

and S603B, sending the PTZ instruction of the ONVIF to the camera equipment.

In this embodiment, steps S601B to S603B are a second execution manner of step S6.

By executing steps S601B-S603B, the compatibility between the camera device using the ONVIF protocol and the upper monitoring platform using the GB28181 protocol can be achieved, and even if the camera device and the upper monitoring platform using different protocols can also receive and transmit data, the PTZ control function of the upper monitoring platform is achieved, which is equivalent to converting the camera device using the ONVIF protocol into the camera device using the GB28181 protocol without replacing hardware of the camera device.

S601C, when the upper monitoring platform needs to play back a video, acquiring a video playback instruction of GB28181 from an instruction issued by the upper monitoring platform;

S602C, converting the video playback instruction of GB28181 into a video playback instruction of ONVIF;

S603C, sending the video playback instruction of the ONVIF to camera equipment;

S604C, acquiring audio and video streams from the camera equipment;

S605C, converting the audio and video stream into a format supported by a GB28181 protocol;

and S606C, transmitting the audio and video stream to a superior monitoring platform.

In this embodiment, steps S601C to S606C are a third execution manner of step S6.

By executing steps S601C-S606C, the compatibility between the camera device using the ONVIF protocol and the upper monitoring platform using the GB28181 protocol can be achieved, and even if the camera device and the upper monitoring platform using different protocols can also receive and transmit data, the video playback function of the upper monitoring platform is achieved, which is equivalent to converting the camera device using the ONVIF protocol into the camera device using the GB28181 protocol without replacing hardware of the camera device.

In conclusion, by executing steps S1 to S6, the camera device using the ONVIF protocol can be made compatible with the upper monitoring platform using the GB28181 protocol without replacing hardware of the camera device, which is equivalent to converting the camera device using the ONVIF protocol into a camera device using the GB28181 protocol; the steps S1-S6 can be realized through computer software, new hardware equipment does not need to be purchased, and the original camera equipment can be continuously used, so that the use cost is reduced, the public network does not need to be connected, the bandwidth or data safety problem does not need to be considered, the software function is special, and the cost performance is high.

In this embodiment, the method for converting the ONVIF device to the GB28181 device further includes the following steps:

s7, periodically calling the ONVIF to carry out heartbeat detection on the camera equipment;

s8, establishing an ONVIF equipment list;

and S9, according to the ONVIF equipment list, carrying out directory query of GB 28181.

Steps S7-S9 may be performed on the basis of performing steps S1-S6.

In step S7, the request for acquiring device information of ONVIF may be periodically called to determine whether the camera device is online, so as to implement the heartbeat function of GB28181 and keep the camera device normally in use.

In steps S8-S9, the directory query function of GB28181 is implemented by the list of ONVIF devices that have been added. Specifically, a GB28181 client can carry multiple devices to register together with the upper platform, where the device list (how many devices are contained) of the current client is detected through a device directory query instruction. And caching data information of the equipment, such as national standard numbers, online states and equipment information, in the server while adding the camera equipment in the second, third and fifth steps. The data may be returned to the upper level platform as the device directory for the client.

The same technical effects as those of the conversion method from the ONVIF device to the GB28181 device in the embodiment can be achieved by writing a computer program that executes the conversion method from the ONVIF device to the GB28181 device in the embodiment, writing the computer program into a computer apparatus or a storage medium, and executing the conversion method from the ONVIF device to the GB28181 device in the embodiment when the computer program is read out and run.
