Automobile assembly plant: A moving relief man. Solved with a call bell system.

Automobile assembly plant: A moving relief man. Solved with a call bell system.

Are you having trouble finding a relief worker when you need help during work? Sonnet-kun can come right away and contribute to reducing "choco stops."

A wireless Andon system has been introduced for the purpose of "calling the relief man in times of trouble." ★ We were able to reduce the "choco stop time" that halts the process. ■ Main issues during "times of trouble": - There are scratches on the parts - The worker cannot make a judgment - There is an abnormality with the equipment - I need to go to the restroom - I feel unwell ■ Before implementation: Workers: They would go to call the relief man when in trouble. Relief man: He was wandering around the site to check for any issues. ■ After implementation / Usage: - Workers carry a card-type transmitter and press it when in trouble (a slim-type transmitter is installed in places where it cannot be held). - The relief man goes to the called location to resolve the issue. - A one-sided receiver with a rotating light and buzzer is installed in a visible position. - Even if the one-sided receiver is not visible, it can be checked with a mobile receiver. The order of calls can also be seen in the history. ■ Log data collection: Log data can be generated on a computer. The one-sided receiver is LAN-compatible, and with the log generation software, the called number and time are saved in a CSV file. The computer is dedicated to log collection and is set to prevent sleep mode to continuously collect logs.

School bus abandonment prevention system. Released in July 2023. Designed specifically for microbuses. Wagon types like Hiace are not usable. Compatible with all vehicle models (horn requires separate installation) CAPS-189B, released simultaneously! To all those managing shuttle buses, As of April 2023, safety devices for school buses have become mandatory. The installation of devices that meet the safety device guidelines set by the Ministry of Land, Infrastructure, Transport and Tourism has been made compulsory. We propose a system that requires confirmation upon disembarking. Benefit 1: Low Cost Only the cost of the equipment itself is needed, making it inexpensive and easy to implement. Benefit 2: Easy Installation Installation can be easily done by anyone, eliminating the need for installation costs. Benefit 3: Habitual Visual Confirmation Rather than relying solely on the device, make the most reliable visual check a habit. 1. Departure: Engine ON - Announcement from the unit installed in the driver's seat. 2. Arrival: Engine OFF - Announcement from the unit. 3. Press the button installed at the rear to check if anyone is left inside the vehicle and press the button. If you do not confirm and do not press the button... an abnormal alarm will sound loudly.
