In today's increasingly serious global environmental problems, the proper treatment of urban domestic waste is one of the important starting points to improve environmental quality. In terms of urban waste treatment, Germany is second to none in the world.
First of all, Germany has passed legislation to let manufacturers control waste from the source. People all over the country consciously perform waste classification and there will be special recycling places for special waste.
The waste treatment modes of cities all over the world have their own advantages. Some countries are not only free from waste, but also can turn waste into treasure through recycling while keeping the environment clean.
Aiming at the problem of waste management, Finland has long used sensor trash can for systematic management of waste bins. Ultrasonic sensors mainly transmit the collected sensor data of waste bins and waste recycling places to waste recycling stations thousands away through low-power networks and then to servers.
By analyzing the data, the dustbin management station can intuitively understand the saturation state of dustbins in various regions through the sensor trash can provided by trash bin manufacturers and arrange appropriate routes for cleaning vehicles to save costs for environmental protection.
1. Automatic sensing function
Traditional dustbins generally need manual or foot stepping, but the dustbin feels very dirty. There are many bacteria on it and everyone is reluctant to touch it. The cover of the sensor trash can is opened and closed through the sensor. For example, when you want to throw garbage in kitchen, just approach the dual sensor kitchen bin and the cover will open automatically. It will close automatically 3-4 seconds after throwing. You don't need to touch the bucket at all. It can completely solve the potential safety hazards and effectively prevent the spread of mosquito bacteria.
2. Detection function of whether the trash can is full
There are garbage cans in every corner of the city, but the filling degree of each garbage can is different. In terms of management, it is impossible to deal with it in time all the time. Some dustbins are full and overflow. There is rubbish everywhere. Flies and mosquitoes fly all over the sky. It's disgusting. Some have only a little garbage. It is impossible for sanitation workers and garbage trucks to check every garbage can every day and clean it in time, which requires a lot of human, material and financial resources. Sensor trash can generally monitor the amount of garbage in the trash can through infrared sensor or ultrasonic sensor. When it is detected that the trash can is almost full, the garbage can be compressed through high-energy compressor. When the garbage is full again, it will automatically connect to the Internet and send the location to the garbage transfer station for people to clean up the garbage.
The problem of using sensor trash cans to deal with garbage has sprouted. According to data statistics, by reducing vehicle fuel and labor costs caused by unnecessary garbage recycling, the information data transmission system established by using ultrasonic sensors can help environmental sanitation institutions save 20% - 40% of operating costs.
