Title: Hiroyuki Ikegami: Innovator in Photovoltaic Technology and Survey Systems
Introduction
Hiroyuki Ikegami is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the fields of photovoltaic technology and surveying systems. With a total of 5 patents to his name, Ikegami continues to push the boundaries of innovation.
Latest Patents
One of his latest patents is a "Transmission device for current signal of solar string." This invention provides a technique capable of improving the signal-to-noise ratio (SN ratio) of a current signal superimposed on a power line in a photovoltaic string. It efficiently specifies a failure location by connecting a current source to a power line in parallel with each photovoltaic element. A controller manages the current value of the current source to generate a current signal. Additionally, a bypass capacitor is connected to the power line, allowing it to transmit the current signal from the negative electrode side to the positive electrode side of the photovoltaic string.
Another notable patent is a "Survey system," which includes a movable photographing device, a surveying device, and an analysis device. The movable photographing device features a camera mounted on a UAV that captures multiple images for photogrammetry. It also includes a GPS unit that timestamps the photographing time on each image. The surveying device determines the position of the movable photographing device and timestamps the surveying time on the survey results. The analysis device associates each survey result with the respective photographing position, generating data for photogrammetry.
