Case Studies
This section contains case studies on AIoT-related products and systems.
It details the services of EcoBike and GreenBike, which are public bike systems in Korea. This product is a smart traffic information system for pedestrians. While pedestrians are waiting for the signal at crosswalks, this system detects jaywalking in advance and provides voice warning messages. In particular, EcoBike has established a system capable of accommodating over 3,000 bicycles across approximately 160 stations for rental and return.
This configuration diagram illustrates a system configuration that enables rental and return between stations and bicycles using ZigBee and RFID.
The emergency bell uses a proprietary ZigBee interface and is a system that operates by configuring a mesh network.
** Introduction to Anyang City's Smart Transportation City System and Voice Guidance Assistance Device The Smart Transportation City System was developed to establish smart road infrastructure based on central road traffic control and autonomous driving services. The system consists of an autonomous shuttle bus operation designed to provide user safety and convenience, a central control system for monitoring and managing shuttle operation status, road traffic conditions, and smart road service operations, and a Smart Pedestrian Care System linked with a traffic signal control system for pedestrian safety. As part of the Smart Pedestrian Care System, our company has developed a Smart Voice Guidance Assistance Device that broadcasts warnings to pedestrians exhibiting dangerous behavior at crosswalks and surrounding areas within autonomous driving zones. By linking with traffic signal controllers, the Smart Voice Guidance Assistance Device broadcasts warnings regarding detected jaywalking and transmits status information to the central control server, ensuring the smooth operation of the autonomous driving and smart road systems. Key functions of the Smart Voice Guidance Assistance Device include voice guidance broadcasts based on pedestrian signals, a Text-to-Speech (TTS) function that converts specific messages from a remote server into voice broadcasts, and a function that transmits real-time information, such as jaywalking situations, to the server.
** Introduction to the Wirye District Tram Operation System and Voice Guidance Auxiliary Devices The tram operation system is a control system that monitors tram operations, track conditions, and signal operation status. Through integration with the road traffic signal system, it also includes the function of controlling voice guidance devices for pedestrian safety. The tram operation system consists of the control center's server control unit, tram signal control unit, traffic signal control unit, and voice guidance auxiliary device unit. The voice guidance auxiliary device unit, developed and installed by our company, provides a function to promote pedestrian safety by broadcasting voice guidance for each pedestrian signal through integration with the tram traffic signal controller. Key functions of the voice guidance auxiliary device include pedestrian signal detection based on integration with the traffic signal controller, detection of pedestrians within crosswalks installed on the tram tracks, voice guidance broadcasting based on integration with audible signals for the disabled, and voice guidance broadcasting based on remote commands from the server control unit.
