Problems solved by technology

[0002] In the wireless transmission service (Wireless Kit), the network camera (IPC, IP Camera) needs to scan the wireless AP first to obtain its Received Signal Strength Indication (RSSI, Received Signal Strength Indication) when connecting to the indoor wireless access point (AP, Access Point). ), and then select the link connection according to the strength of RSSI. After the connection is successful, it will take a period of data transmission to judge whether the currently selected link is suitable for video transmission. If the current link quality is poor, you need to disconnect and restart. As a result, the wireless IPC takes a long time to judge the entire link

Abstract

The invention discloses a link quality judgment method, a network camera and a computer readable storage medium. The method comprises the following steps: acquiring working channel information broadcasted by routing equipment; detecting each channel of the routing equipment based on the working channel information to obtain evaluation parameters of the channels; and scoring the evaluation parameters to obtain a quality score of the channel. According to the method, the link quality can be quickly and accurately judged.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a link quality judging method, a network camera and a computer-readable storage medium. Background technique [0002] In the wireless transmission service (Wireless Kit), the network camera (IPC, IP Camera) needs to scan the wireless AP first to obtain its Received Signal Strength Indication (RSSI, Received Signal Strength Indication) when connecting to the indoor wireless access point (AP, Access Point). ), and then select the link connection according to the strength of RSSI. After the connection is successful, it will take a period of data transmission to judge whether the currently selected link is suitable for video transmission. If the current link quality is poor, you need to disconnect and restart. As a result, the wireless IPC takes a long time to determine the entire link. Contents of the invention [0003] The present application provides a link ...
