[MGI30-P08] Visual IoT Transmission System with Low Power Consumption Using a One-board Microcontroller from a Place without a Commercial Power Supply
Keywords:Video transmission, Low Power Comsumption, One-board microcontroller
Abstract
For the purpose of watching over the area or monitoring disasters, a video transmission system that operates with as low power consumption as possible using a solar panel and a battery is desirable when a camera is installed in a place without a commercial power supply.
Introduction At last year's conference, we proposed a system using a Raspberry Pi powered by a solar panel and battery as a method of video transmission from a place without a commercial power supply.
This paper reports on a video transmission system that uses an Arduino board, a one-board microcontroller that operates with even lower power consumption than the Raspberry Pi and does not need a commercial power supply.
System configuration Figures 1 through 5 show, respectively, an image of a possible installation of this system, a system configuration diagram, a photograph of the system actually mounted on a freestanding stand, a photograph of a microcomputer board with a built-in camera, and a waterproof case housing the battery and charge controller.
The system is pre-programmed to upload images from either the SPI camera embedded on the microcontroller board or an externally installed ONVIF IP camera via mobile network to a web server at the same intervals.
In this system, it is not possible to remotely change the capture interval or the number of pixels in the camera image as in the video transmission system using the Raspberry Pi, and the program must be written directly to the microcontroller board from a PC in advance. However, the power consumption of the Raspberry Pi alone is always around 6 to 8W, whereas this system requires only 1W even when the built-in camera is working, making the entire system including a solar panel and a battery more compact.
The image transmission time for the built-in camera is less than 3 minutes for 1600 x 1200 pixels, and about 8 minutes for the maximum 2048 x 1536 pixels.
Issues for future consideration When an externally installed ONVIF IP camera is used, pan-tilt and other camera operations must be performed via http, and since a program for this is currently under development, future experiments based on this program are an issue.
Conclusions We reported on a low-power visual IoT transmission system using a one-board microcomputer with a solar panel and a battery as a method of installing an IP camera for disaster monitoring and other purposes in a location where a commercial power source is not available.
