Embodiment 1

[0036] Embodiment 1. The discovery message of the ONVIF discovery process is a Hello message sent by the NVT, and the NVT actively announces its own services in the network.

[0037] Such as figure 2 shown, including the following steps:

[0038] Step S1, the NVT accesses the wireless access point AP, and actively sends a notification message carrying the SSID of the accessed AP in the network through multicast to announce its own service.

[0039] In this embodiment, the video devices in the video surveillance system are interconnected and intercommunicated through the ONVIF protocol. After the NVT accesses the wireless AP, it actively announces its own service in the network through the multicast announcement message Hello message.

[0040] In this embodiment, the Hello message carries a field whose field type is APSSID, and the content is the SSID of the wireless access point AP connected by the NVT.

[0041] Step S2, the wireless access point AP receives the notification...

Embodiment 2

[0047] Embodiment 2: The discovery message of the ONVIF discovery process is the Probe message sent by the NVC, and the NVC actively detects and monitors the front-end NVT in the network.

[0048] Such as image 3 shown, including the following steps:

[0049] Step F1, the NVC accesses the wireless access point AP, and actively sends a detection message carrying the SSID of the accessed AP in the network through multicast.

[0050] The mobile monitoring platform NVC approaches the wireless access point AP while moving, and automatically establishes a wireless connection with the AP. Then actively send a Probe message carrying the SSID of the accessed AP. In this embodiment, the Probe message carries a field whose field type is APSSID, and the content is the SSID of the wireless access point AP accessed by the NVC.

[0051] Step F2, the wireless access point AP receives the detection message sent by the NVC, queries the SSID carried in the detection message, compares it with ...

Abstract

The invention discloses a method for automatic discovery of a network video transmitter (NVT) through a mobile monitoring platform. An ONVIF protocol is expanded, and a discovery message in an ONVIF discovery process carries identification information of an AP accessed by a sender of the discovery message, such that the mobile monitoring platform NVC can automatically discover the NVT, obtains equipment information of the NVT and initiates a service request for the NVT according to the obtained equipment information. According to the method provided by the invention, the mobile monitoring platform NVC can automatically discover the NVT, and at the same time, the multicast discovery message is only forwarded in the AP, such that message flooding of discovery messages of an ONVIF, caused because a destination address is a multicast address, can be reduced.

Description

technical field [0001] The invention belongs to the field of video technology, in particular to a method for a mobile monitoring platform to automatically discover a monitoring front end. Background technique [0002] With the development of the video surveillance industry, wireless video surveillance is becoming more and more common. Each surveillance front-end NVT (NetworkVideoTransmitter), including encoders and network camera IPCs, can be connected to the network wirelessly to monitor the client or mobile The monitoring platform NVC (NetworkVideoClient) can also be connected to the network wirelessly. [0003] At present, the video monitoring system of Safe City includes many wireless monitoring parts. The network camera IPC is connected to the wireless access point AP. The video images collected by the network camera are live-streamed to the mobile monitoring platform. In addition, after the mobile monitoring platform on a mobile vehicle such as a subway train or a bu...
