Contents of the invention

The object of the present invention is to provide a substation video surveillance system based on SIP protocol for cross-domain cruising, which realizes the hierarchical, layered and domain-specific cruising functions of the upper and lower platforms in order to solve the above problems.

In order to achieve the above object, the present invention adopts the following technical solutions:

The present invention includes a lower-level platform, an upper-level platform and a SIP protocol gateway, the lower-level platform includes a lower-level Web server, a lower-level management server, a lower-level communication server and a plurality of cameras, and the described upper-level platform includes an upper-level Web server, an upper-level management server and an upper-level communication server The signal output ends of a plurality of said cameras are respectively connected to the video signal input ends of said lower-level Web server, the management communication port of said lower-level Web server is connected to said lower-level management server, and the network communication interface of said lower-level Web server Connected to the lower-level communication server, the control signal input end of the lower-level communication server is connected to the control signal output end of the lower-level management server, and the remote communication port of the lower-level communication server is connected to the upper level through the SIP protocol gateway The remote communication port of the communication server is connected, the upper-level communication server is connected with the network communication interface of the upper-level Web server, the management communication port of the upper-level Web server is connected with the upper-level management server, and the control signal of the upper-level communication server The input end is connected with the control signal output end of the upper management server.

In practical applications, the upper and lower platforms can manage camera preset position information and set different cruising routes according to their own needs. When setting camera presets, you can encode different presets of the same camera. Since the use of the upper and lower platforms is layered and divided into domains, the use of cameras by each platform is different and irrelevant, so it is necessary to satisfy the requirements that the upper and lower platforms can use the same camera differently according to their own needs. The upper and lower platforms do not need to interact with the preset information set separately, but only need to use different codes to distinguish the preset positions of the camera, for example, use 1-50 to represent the presets set by the lower platform For setting information, use 51-100 to represent the preset information set by the superior platform. The upper and lower platforms add corresponding cruising routes to the pre-position information set respectively to realize the hierarchical, layered and domain-divided cruising function.

The beneficial effects of the present invention are:

In the present invention, the upper platform and the lower platform set different preset information for the same camera according to the actual business needs, and formulate the cruising route according to the preset information, so as to realize the cruising function of the upper and lower platforms.

Below in conjunction with accompanying drawing, the present invention is described in further detail:

As shown in the accompanying drawings, the present invention includes a lower-level platform, an upper-level platform and a SIP protocol gateway. The lower-level platform includes a lower-level Web server, a lower-level management server, a lower-level communication server and a plurality of cameras. Among the figures, the cameras include a first camera, a second camera, ..., the Nth camera, the upper-level platform includes a higher-level Web server, a higher-level management server, and a higher-level communication server. The server is connected, the network communication interface of the lower-level Web server is connected with the lower-level communication server, the control signal input end of the lower-level communication server is connected with the control signal output end of the lower-level management server, and the remote communication port of the lower-level communication server is connected with the upper level through the SIP protocol gateway. The remote communication port of the communication server is connected, the upper-level communication server is connected with the network communication interface of the upper-level Web server, the management communication port of the upper-level Web server is connected with the upper-level management server, the control signal input terminal of the upper-level communication server is connected with the control signal output of the upper-level management server end connection.

As shown in the attached figure, in the application, the city-level substation platform is used as the lower-level platform, and the provincial-level substation platform is used as the upper-level platform. The upper-level platform and the lower-level platform configure different preset position information of the station-side cameras according to the needs. Each camera corresponds to different monitoring areas according to different preset position information, and uses different codes to distinguish them, so that the upper-level and lower-level platforms can distinguish the same Different preset positions for cameras. After the preset position is set, the upper and lower platforms can formulate corresponding cruise routes according to the preset position information to realize hierarchical, layered and domain-specific cruises.

Combined with the accompanying drawings, the following uses the specific resource push process to describe the process of setting preset positions on the upper and lower platforms and realizing hierarchical, layered, and domain-specific cruising:

1. After the lower-level platform registers with the upper-level platform through the standard SIP process (Http Digest) authentication method, the upper-level platform knows that the lower-level platform is online;

2. The upper-level platform and the lower-level platform respectively set the preset position information of the camera according to their own needs, and encode different preset position information, and this information is stored in the camera.

3. The upper-level platform and the lower-level platform respectively set the cruise route on this platform according to the camera preset information.

4. When the lower-level platform calls the cruising route of this platform, it directly transfers the control action of the cloud mirror (including the PTZ, lens and auxiliary equipment) to the encoding device to complete the review of the cruising route.

When the upper-level platform calls the cruising route of this platform, according to the preset position of the camera, the upper-level platform sends INFO to the lower-level platform to control the PTZ (including PTZ, lens and auxiliary equipment), and the message carries the user level and command action; PTZ After the control action is transmitted to the encoding device, the lower-level platform returns a success or failure response. After success, the upper-level platform can successfully access the video resources set in the cruise route.
