Method for implementing wireless multimedia sensor node apparatus

Abstract

The invention discloses a realization method for the node device of wireless multimedia sensors. A video sensor module (1) takes a processor module (11) as the core to coordinate all tasks and uses a complex programmable logic component module (13) to provide a high frequency clock to cooperate with a video collection module (12). Meanwhile, the processor module (11) can set the parameters of an imager by I 2 C serial communication interfaces and shares a SRAM (static random access memory) module (14) and a flash module (15) with the complex programmable logic component module (13) by a data bus and an address bus; the software system of the video sensor module is compiled by adopting nes C language, and is operated in a Tiny OS (17) operation system environment, which mainly comprises the realization of the following three components: a driving program (18), a database function set (19) and a sensor application program (20). The node device is low in design cost and can be deployed at a large number in a detection area in order to achieve better coverage.

Description

technical field [0001] The invention relates to a solution method for video application in the field of wireless communication, which belongs to the intersection field of embedded development and computer network technology. Background technique [0002] With the rapid development and maturity of communication technology, embedded computing technology and sensor technology, miniature sensors with perception, computing and communication capabilities have begun to appear and have attracted great attention. The resulting sensor network can coordinately perceive, collect and process various environmental or monitoring object information in the network coverage area, and release it to users who need this information. The sensor network integrates the logical information world and the real physical world, which profoundly changes the interaction between human and nature, and can be widely used in many fields such as military, industrial and agricultural control, biomedicine, and e...

AI Technical Summary

Problems solved by technology

[0006] During the research process, the inventor found that most of the existing wireless multimedia sensor node design schemes are biased towards applications that require high power consumption and high video quality, which requires the nodes to have strong processing capabilities

However, there are relatively few video solutions for some lightweight hosts with low power consumption and simple processing capabilities, so some applications with limited energy consumption and low image quality requirements in real life are limited.
