One morning, I was about to send my son to school. Suddenly my son said to me: "Dad, stop driving, let's take the bus together!"
I was curious to ask him why, and my son said to me solemnly: "The teacher said that everyone now promotes green travel, and car exhaust will pollute the environment and affect human health."
Hearing what my son said, I was very moved. Every child understands low-carbon, environmentally friendly and green travel. How can we as parents not support it!
When I got on the bus, my son asked, why did the bus tell us which station to go to and how did it know?
This can stump me, hurry up and popularize science!
Check the information through Baidu Encyclopedia, in fact, every bus will be equipped with an intelligent bus stop announcer. This automatic stop announcer is based on the global satellite positioning system, which realizes the automatic stop announcement of the bus without manual operation.
It is almost the same as the navigation on a private car. The staff will first store all the stops passing by on the way into the stop announcer and collect the coordinates.
When the bus enters the coordinate range (under normal circumstances, the distance between the bus and the station is about 20 meters), the stop announcer will accurately predict the name of the station. When the bus leaves the preset range of the station coordinates, the stop announcer will predict the name of the next station.
In addition, the bus stop announcer also supports dialect announcements, which is why we can hear local dialect announcements or English announcements on the bus.
