Method for self-adapting regulation of running parameter and monitoring frontend equipment

Abstract

The invention aims at providing a method for adjusting the working parameters adaptively and a monitoring terminal equipment; in this way, the monitoring front terminal can adjust the working parameters adaptively according to the monitoring pattern; on one hand, the video and audio information quality could be altered and storage space can be saved; on the other hand, a plurality of areas could be monitored with one monitoring front terminal, which is characterized in simple operations and promoted monitoring performance.

Description

technical field [0001] The invention relates to the field of monitoring, in particular to a method for adaptively adjusting working parameters and monitoring front-end equipment. Background technique [0002] A monitoring system usually includes a monitoring front end, an information transmission part and a monitoring terminal. Among them, the main work of the monitoring front end is to obtain the audio and video information of the monitored area, process the audio and video information, and transmit the processed audio and video information to the monitoring terminal through the information transmission part. Some monitoring front-ends are also equipped with an audio and video intelligent analysis module. The audio and video intelligent analysis module performs intelligent analysis such as motion detection and decibel detection on the collected audio and video information, and judges whether there is an abnormal situation and the current situation based on the analysis resu...

Problems solved by technology

[0003] Usually, the monitoring front-end needs to perform a series of processing on the collected audio and video information, such as A / D conversion, compression coding, etc., and as the main parameters for processing audio and video information, they are all set to a fixed value, so that even In the state where there is no alarm, the monitoring front-end still needs to process the current audio and video information with the parameters used to process audio and video when an alarm occurs, which will lead to a waste of storage space, and in some cases it is difficult to meet the user's requirements.

For example, in the alarm state, the resolution of the video surveillance image is a fixed value; while in the non-alarm state, the user does not have high requirements for video quality, and if the image resolution in the alarm state is still used at this time, it will Causes a waste of storage capacity; and when the alarm enters a more advanced state, the user needs to obtain a higher-quality image and hopes to increase the resolution of the image. Since the resolution of the video surveillance image cannot be adaptively adjusted in the prior art, it is difficult to meet the user request

[0004] Another situation is that the monitoring system in the prior art usually sets a monitoring front end with a fixed monitoring direction for each monitoring position, which will increase the complexity of system implementation and increase the cost

Therefore, in some monitoring solutions that are more sensitive to system costs, such as home monitoring systems, it is necessary to use one monitoring front end to monitor multiple monitoring areas; Mode or fixed direction plus stepping mode to adjust the direction of the monitoring front end. In this way, when switching between multiple monitoring areas, the remote user has more operating procedures. Due to the possible delay in line transmission, the precise control and real-time performance of the system are at a certain level. Difficult to achieve satisfactory results in some applications
