Embodiment Construction

[0046]The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] At present, the router will prohibit some ports from interacting through NAT, which will cause data to fail to pass through NAT. For example, when the client obtains the audio and video data of the monitoring device in the NAT, because the RTSP port 554 is disabled, the audio and video streams cannot be transmitted through NAT. , the actual situation and playback black screen will appear on the client side. However, the actual e...

Abstract

The invention discloses a method, device, device, system and computer-readable storage medium for establishing a connection between monitoring equipment; After the response, if the next request sent by the client is not received, the monitoring device automatically modifies the mapping relationship between the router and the monitoring device by replacing the original port with the alternate port, so that the response request can be sent to the client through the modified mapping relationship. , in order to successfully establish the connection between the client and the monitoring device, so that when the client obtains the live and playback data of the monitoring device, the black screen will not appear due to the port being disabled by the router; and this cancellation of the original port mapping relationship retains the router. The internal port method can ensure that the NAT networking is normal, and there will be no abnormal flow interruption caused by the change of the internal port.

Description

technical field [0001] The present invention relates to the technical field of data interaction, and more particularly, to a method, apparatus, device, system and computer-readable storage medium for establishing a connection between monitoring equipment. Background technique [0002] At present, in the field of monitoring, the commonly used standard networking is NVR (Network Video Recorder, network video recorder) and IPC (IP CAMERA, network camera) under the local area network, through the router port mapping to the external network, through RTSP (Real Time Streaming) Protocol, real-time streaming protocol) for audio and video stream transmission for remote access by users, see figure 1 , is a schematic diagram of a common monitoring network in the prior art, through figure 1 It can be seen that the NVR and IPC perform audio and video interaction with the cloud service website of the WAN and the mobile client through the router. However, at present, some common routers ...
