Smart Trigger

Smart Trash Bins are of the products that promote the smart city concept. The most favorable feature of a smart trash bin is its intelligence. Equipped with various kinds of sensors on the front, a smart trash bin is able to detect temperature, humidity, odor, smoke, and even can automatically send alerts when it is full or overstuffed. In other words, a smart trash bin as such can sense its fullness, and therefore, to inform sanitation workers so that they can clean it up on time.

TF Series LiDAR developed by Benewake achieves intelligent and touch-free garbage recycling. It provides two solutions for monitoring a trash bin – detecting if lid is open, and measuring the height of garbage within. Benewake LiDARs have already been applied on smart trash in many cities. These smart trash, not only being able to facilitate touch-free waste disposal, will also send real-time data to garbage trucks and request garbage collection when they are 80% full. Therefore, seamless garbage collection and transportation becomes possible. 

LiDAR Application on Smart Trash

1. Automatic Lid-opener: The product features an automatic lid-opener. When installed above a garbage recycling station and facing down to the front ground, the LiDAR is able to detect people (taller than 130cm) coming from the front. When people who come to disposal of the garbage approach, the lid of the bin will be automatically opened, so as to make people’s hands free from touching it. In this way, we can reduce the possibility of bacterial infections, and make garbage disposal trouble-free for citizens.

2. Garbage Amount Measuring System: Installed on the inner top of the lid and facing downwards, the LiDAR is able to measure garbage amount within a trash bin. When garbage amount reaches 80% of bin’s capacity, it sends data to a garbage truck to request garbage pickup. In this way, seamless garbage collection becomes possible. 

Solution Advantages 

1. Long detection range for black trash, 2° detection angle to prevent false alarms caused by touching the bin walls.

2. Low power consumption (<0.35W), supports battery power; 100Hz high-frequency precise real-time measurement, configurable parameters, safe for human eyes.

3. Plug and play, consumer-level pricing, lighter than a one-yuan coin, easy to install and integrate, modular structure, can be equipped with a protective casing.

4. Smart waste management helps reduce the overall collection and transportation costs of waste by nearly 50%.

This solution applies LiDAR to control the opening and closing of automatic doors, especially in office areas, shopping malls or factories where there is a lot of traffic. The use of wall buttons or pushing doors is inconvenient, therefore automated door opening solutions are needed to reduce crowding and improve accessibility.

The Application in Benewake's Office

Trigger Scheme of Roller Shutte Switch LiDAR

Install a single-point LiDAR TF-Luna, TFmini Plus or TF02-Pro above the roller shutter door to detect the designated area diagonally downward. Different installation heights / angles can choose products with different ranges.

Place markers on the ground (the position of the radar spot can be observed with an infrared camera). Whenever a vehicle or person enters a marker, the change in distance is detected to determine whether a vehicle or person has entered, triggering the automatic opening of the rolling shutter door. After the vehicle or person leaves the marker, the change in distance is detected to trigger the automatic closing of the rolling shutter door.

Distance Commissioning

Firstly, power on the sensor after fixing it and the red light on the sensor will light up; when the obstacle in front of the sensor is less than 0.2m or more than 8m, the orange light will light up to indicate that it is out of range. Place an obstacle directly in front of the sensor within the protective distance of the sensor and press and hold the SET button on the sensor (for more than 3 seconds), the red light will flash and the green light will go out, at which point the distance setting is complete.

After the distance setting is completed, as long as there is an obstacle within the set distance, the green light on the sensor will light up and a switch signal will be output to the automatic door through the relay to realise the automatic door open state. When the obstacle leaves, the automatic door will be closed.

Note: The factory protection distance is set at 2.5m, which can be reset according to the usage requirements.

Customer Benifits

Trigger scheme of roller shutte switch LiDAR achieves moving from manual control to automatic control. It reduces the duplication of workers' work caused by opening doors and improves the efficiency from the side, making the workers' labour experience rise. Our LIDAR installed on the customer's roller shutter door works well, with accurate detection and no false alarms. It has won the praise of both the customer and the workers.

Projector Assisted Focusing / Elevator Projection Advertising Switch Control

Installing TF-Luna inside the projector for automatic or assisted focusing upon projector activation ensures optimal projection quality and clarity.Elevator Projection Advertising: The radar detects the distance of obstacles in front. If the distance is greater than the actual distance from the radar to the elevator door, it assumes the elevator door is open and doesn't activate the projector. Otherwise, it activates the projector.

Solution Advantages 

1. Technical Advantages: Active detection, compared to camera algorithms, it has a smaller data footprint, is unaffected by changes in ambient light, enabling more accurate and efficient judgment, with precise ranging and stable high performance.
2. Implementation Advantages: Modular design facilitates integration.
3. Competitive Advantages: More reliable than distance analysis through image algorithms, not affected by projector light interference.
4. Product Advantages: High cost-performance ratio, small footprint, low power consumption.

TF-Luna detects whether individuals have entered the access control turnstile and triggers auxiliary facilities such as sound and light signals, as well as opening the turnstile. TF-Luna detects the presence of individuals near the automatic door and controls the automatic door's opening and closing.

TF-Luna detects whether someone is passing near a street light and triggers the automatic switching on of the street light.

1. Technical Advantages: High precision, narrow field of view, stable and reliable ranging, immune to lighting interference, low false alarm rate, high refresh rate. 
2. Implementation Advantages: Small size, modular design for easy integration. 
3. Competitive Advantages: More stable and reliable than infrared, resistant to interference. 
4. Price Advantages: Consumer-level pricing. 
5. Product Advantages: Wide voltage design (DC8~36V/AC8~24V), suitable for automatic door voltage requirements.
