Recently, I came across an interesting project showcased at the 2nd Hubei Province College of Physics Experiment Innovation Design Competition held at Jianghan University. This invention, developed by four students from Wuhan Engineering University, caught my attention. Their creation is an electric vehicle speeding alarm system that aims to enhance safety by monitoring and controlling the speed of electric vehicles.
Imagine this: as soon as an electric vehicle approaches its maximum speed limit—set at 25 km/h—the device triggers a voice alert. If the rider continues to exceed the limit, the system doesn’t just warn but takes action. It reduces the current supplied to the motor via a computer chip, forcing the vehicle to slow down automatically. This feature could potentially prevent accidents caused by reckless speeding.
One of the designers, Jiang Liang, who specializes in measurement and control systems, explained how they managed to keep the cost of this device low. He emphasized that integrating this technology into electric vehicles wouldn’t significantly impact their overall production costs. This makes the idea even more appealing for manufacturers looking to improve safety without adding too much expense.
The team’s approach was collaborative and systematic. They worked together to assemble various components like sensors, SCM (Single-Chip Microcomputer), displays, buzzers, and voice chips into what they call an “electric vehicle speeding alarm.†Through multiple trials, they fine-tuned the device to ensure its effectiveness. For instance, if drivers ignore initial warnings, the system escalates its response with repeated audio alerts urging them to slow down. Should these warnings go unheeded, the device intervenes directly by cutting off power supply.
What struck me most about their presentation was not only the technical innovation but also the potential real-world benefits. With urban areas increasingly adopting electric vehicles, ensuring safe usage becomes crucial. Projects like this one highlight how creative solutions rooted in physics experiments can address practical challenges faced daily on our roads.
Overall, while attending this competition gave me insight into cutting-edge student projects, it also reminded me of the importance of fostering such initiatives globally. Encouraging young minds to explore inventive ways to solve everyday problems ensures progress toward smarter cities and safer communities.
