Problems solved by technology

[0005] The application scenarios of the existing GB28181 protocol make it impossible for the public security platform to monitor network devices other than the public security platform at any time through the external network, so it is impossible to conduct timely emergency dispatch based on real-time images

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] like figure 1 In the described embodiment, the SIP protocol wireless network monitoring method under GB28181 specifically includes the following steps:

[0026] (1) The IPC starts the GB28181 module, and according to the set SIP_SVR, device id and port number, forms a SIP registration package and registers with the SIP_SVR central server;

[0027] (2) After the SIP_SVR central server is started, it monitors the configured IP and port. When receiving the SIP registration packet, it judges whether the authentication header is empty; if it is empty, returns a random number to the requested device and enters the next step; if not If it is empty, verify whether the username and password are correct; if it is correct, enter step (4), if it fails, return 401 authentication failure;

[0028] (3) IPC receives a 401 authentication failure error,...

Abstract

The invention discloses a wireless network monitoring method under the SIP protocol under GB28181. It connects to the corresponding sip server in the cloud through the sip protocol, and the sip server controls the interaction, pushes the corresponding RTP data packet to the cloud multimedia server, transcodes it through the decoding module, and monitors it for multiple external network clients through rtmp . The beneficial effect of the present invention is: through the 4G dial-up mode and the sip protocol, the devices in different physical locations are centrally managed and controlled and streamed and played in real time, so that the administrator can manage and control the devices in time, and real-time scheduling can be performed for emergency scenarios.

Description

technical field [0001] The invention relates to the technical field related to security video, in particular to a wireless network monitoring method under the SIP protocol under GB28181. Background technique [0002] GB28181 "Technical Requirements for Information Transmission, Exchange, and Control of Security Video Surveillance Networking System" was proposed by the Science and Technology Information Bureau of the Ministry of Public Security, under the jurisdiction of the National Security Alarm System Standardization Technical Committee (SAC / TC100), and the No. 1 Institute of the Ministry of Public Security, etc. A national standard jointly drafted by the unit. [0003] This standard stipulates the interconnection structure and communication protocol structure of information transmission, exchange and control in the urban monitoring and alarm network system, the basic requirements and security requirements for transmission, exchange and control, as well as the technical r...
