Smart bin is a subdivision product under the concept of smart city. The biggest advantage of this product is “smart”. By installing various types of sensors, the front end of a smart bin not only can detect temperature, humidity, odor, smoke, etc., but is also able to realize the automatic overflow alarm function. In other words, this type of rubbish bin can automatically detect whether it is full or not, prompting users to empty the rubbish bin in a timely manner.

Therefore, how to detect the remaining amount of rubbish in a rubbish bin accurately and rapidly will be an important criterion for testing such sensors. Light Detection and Ranging (LiDAR) uses the Time-of-Flight (ToF) principle to measure distance. By installing LiDAR in a rubbish bin, the distance from the top of the rubbish bin to the rubbish is detected. Then, a message is sent to the monitoring system to determine whether the rubbish bin is full or not. Benewake LiDAR offers two types of detection solutions for different types of rubbish bins.

 

1. Small but tall rubbish bins

 

The Benewake TF Series Distance Sensors can detect the distance of the nearest object in a range of up to 12 m by actively emitting small near-infrared light. The interference of individual special objects can be effectively eliminated without relying on external light sources and the integration of special algorithms.

Feature Overview:


  • Small light spots, which can effectively solve problems related to misjudgments resulted from ultrasonic and microwave detection of bins due to wide detection angles.
  • Small in size, which makes integration easy
  • Very low power consumption, which supports battery power
  • Able to output the distance of the nearest obstacle and simulate switching output
  • Multiple communication ports, which support remote data transmission

2. Large and wide rubbish bins

 

The Benewake CE30 Series 3D LiDAR Sensors have a pure solid-state structure, and emit near-infrared beams through the Flash technology, with a detective field of view of 132° ´ 9°. These sensors can receive signals on 3D horizontal planes, output the distance of the nearest objects and describe the status of rubbish in rubbish bins through point cloud data.

Feature Overview:

Wide field of view, which prevents false alarms due to oversized bins and small detection range of other sensors Two modes available to choose from, i.e. directly outputting distances along the X-, Y- and Z-axes or point cloud data 4m or 28m detection ranges available to choose from Able to output the distance of the nearest obstacles and simulate switching output Multiple communication ports, which support remote data transmission.

With this method of detecting the remaining amount of rubbish in rubbish bins intelligently, waste management-related departments can perform proper monitoring and deploy manpower to provide more accurate data and reduce waste of resources, thereby laying a good foundation for welcoming smart cities and a better life.

 

Data Collecting


Data is the new oil, Clive Humby said it in 2006. LiDAR has benefits of compact size, small power consumption, small data size and privacy protection. Those characters make it the perfect sensor in IoT area. It can be used for traffic flow statistics, not only for vehicles, but for human traffic in shopping centers, theme parks, factories and construction sites.
