Problems solved by technology
However, there is an imbalance between the energy collected by renewable energy and the energy required for wireless video transmission, so it is necessary to design an energy control scheme that combines dynamic energy harvesting and wireless video transmission
At present, there is no wireless video selective transmission scheme for dynamic energy supply combined with dynamic energy harvesting and video summarization technology at home and abroad.

Embodiment Construction
[0069] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.
[0070] The wireless video monitoring node system researched in the present invention based on energy dynamic collection is a video stream efficient transmission scheme that integrates video frame collection and environmental energy extraction technology.
[0071] Such as figure 1 As shown, the system includes two independent acquisition sources of video acquisition and energy acquisition, and four parts of signal sending end and signal receiving end. The energy collection process is a random process with the difference of the environment and time, and at the same time, the video collection process is also a random process with the environment change. The energy collected by the energy collection terminal and the video frames collected by the video collection termin...

The invention discloses a wireless network video transmission system based on energy dynamic collection, wherein: the energy collection source is used for random dynamic energy collection with the environment difference and time; the video collection source is used for the environment change Randomly collect video to obtain a video frame summary sequence; the dynamic energy collection and the video collection are imported into the signal sending end, and the signal sending end performs dynamic energy transmission and video frame summary sequence transmission through a wireless channel, and finally reaches the signal The receiving end; the wireless video transmission module, used for wirelessly transmitting the video frame summary sequence received by the signal receiving end. The present invention uses the given energy and the collected video frames to determine the optimal transmission video frame sequence, which provides a reference for the transition from data transmission to video transmission in the development of the Internet of Things, and strongly supports the national green energy-saving industrial technology. development, and contributed to the establishment of a "low-carbon" communications industry.
Description
technical field [0001] The invention relates to wireless video transmission for dynamic energy harvesting. Background technique [0002] When the world is facing serious problems such as energy shortage and climate warming, human beings turn to find and utilize clean energy technologies for survival and development. Clean energy includes solar energy, wind energy, thermal energy, vibration energy, ocean energy, and other energies such as human kinetic energy and biochemical energy. These energies are dynamic and changing, and cannot be used directly. They need to be stored in supercapacitors or chemical batteries with the help of dynamic energy harvesting technology before they can be used. [0003] With the development of science and technology, wireless sensor technology has penetrated into all aspects of human production and life. The wireless communication network has gradually developed to the Internet of Things that can provide communication between any person and an...
