TL;DR: In this article, a remote security supervisory control system for an unmanned facility having a door locking device and a lighting device for internal lights is presented, characterized by comprising a management server (10) which is arranged in a remote site to remote control the locking devices and the lighting device; a detection sensor (20) for detecting a human body in the unmanned facility; a camera for photographing an image when the detection sensor detects the human body, generating image data and transmitting the image data to the management server(10); and a sound collector (40) for collecting a sound

TL;DR: In this paper, a long-distance automatic remote-control monitoring controller for waterworks and sewage is provided to maximize the process efficiency of a dehydrator by using a consecutive sludge density measuring device, and to reduce the electrical energy consumption and chemical costs.

TL;DR: In this article, an IoT-linked smart visible light communication device and method to signal light object peripheries through color light information of an LED signal light, in which a visible light LED ID data communication signal including position information and multi-information of a desired positioning point is emitted, such that visible light communications is performed in a 1:1 target manner between position and multi information toward a smart device and a vehicle adjacent to the light at a short distance of 0.1 m to 10 m.

TL;DR: In this article, a wireless data transceiver with a smart pipe robot located in an old pipe based on wireless communications is proposed to solve the problem of image data and location data are difficult to obtain due to difficulty in stable wireless data communications due to interference and attenuation of a signal.

TL;DR: In this paper, a smart pipe line robot for decrepit pipe line measurement is presented, which comprises a main control board (100) and a smart robot (200) having a long-distance endoscope function.
