Low-power-consumption wireless photographing access and transmission method

Abstract

The invention discloses a low-power-consumption wireless photographing access and transmission method, and the method comprises the following steps that a low-power-consumption camera transmits a network access application to a concentrator, and the concentrator records the field intensity values of all signals transmitted by the low-power-consumption camera to form a field intensity record table;the server reads the field intensity record tables of all the concentrators at set intervals, judges whether the low-power-consumption camera in the field intensity record chart is allocated to the concentrator for management or not; if the low-power-consumption cameras are not allocated, the low-power-consumption cameras are allocated to the proper concentrators according to a camera address allocation algorithm, and then the low-power-consumption camera addresses are issued to the corresponding concentrators by the server by using a camera allocation command; and when the concentrator receives a network access application of the low-power-consumption camera managed by the concentrator, the low-power-consumption camera is configured to enter a network of the concentrator, and the low-power-consumption camera can execute a photographing task only after accessing a certain concentrator. According to the invention, the camera is low in power consumption and cost and high in transmissionrate.

Description

technical field [0001] The invention relates to a low-power wireless camera access and transmission method, which is suitable for low-power wireless camera access, photographing and photo transmission, and is suitable for application scenarios where the camera is powered by a battery and the photos are not continuous and non-real-time , such as the photo taking and transmission of supermarket commodity display management photos. Background technique [0002] In recent years, with the development of the Internet of Things technology and the advancement of image recognition technology, it has brought convenience to the monitoring and management of on-site conditions. However, in many practical applications, the camera can only be powered by batteries, does not need to take pictures continuously, and does not have high requirements for real-time acquisition of pictures. For example, in the display management of supermarket commodities, on-site photos can be obtained regularly ...
