The LiDAR volume detection system is a high-precision detection LiDAR with a 120°*120° wide field of view that generates high-density point clouds. It has built-in algorithms that directly output volume measurements, making it suitable for 3D reconstruction and volume detection systems for targets such as material levels, coal piles, and grain silos. The system integrates different ranges of Benewake TF series LiDARs, with a maximum range of up to 180 meters to meet the distance measurement needs of different customers.
Material level volume detection / Coal pile volume detection / Grain silo volume detection / 3D reconstruction ......
The LiDAR volume measurement system is installed at the top or side of a storage tank to monitor the grain surface distance in real-time. The built-in main control board calculates the remaining material volume in real-time, facilitating timely feed replenishment.
1. Self-Cleaning (Dust Removal) Function
The system includes a wiper configuration to prevent excessive dust from affecting the sensor's distance measurement accuracy.
2. Multi-Line Scanning Function (Adjustable Angle | Speed | Time)
The system includes a servo that sweeps at fixed intervals, performing one back-and-forth sweep between 0° and 120°.
The current highest resolution of the system is one point per degree (14400 points for a 120° scan). The current scan step for the secondary joint is 1° with a 50ms delay (adjustable threshold 20-100ms), and the primary joint step is 1° with a 500ms delay (adjustable threshold about 80ms-1000ms). Scanning 120°120° takes about 60 seconds, and scanning 60°60° takes about 30 seconds. The smaller the angle, the faster the scan time.
3. Wireless Transmission Function
The system is equipped with a wireless transmission module, allowing the wireless monitoring center to receive real-time information on the remaining material volume at the monitored point. The data transmission is stable, and wireless transmission can use LORA to transmit signals to the DTU for transparent transmission.
4. Parameter Configuration
Users can configure the scanning angle, cone angle, self-cleaning time, device self-check, and basic parameters of the silo for secondary development.
5. External Trigger Measurement
Upon receiving an external trigger signal, the system completes a scan and outputs the volume value.
6. Step Grid Scanning Method
By performing arc scans with two rotating servos, the system can generate a grid-like planar map, forming a fitable 3D point cloud.

Coal, as one of the primary sources of conventional energy in the country, is also a crucial pillar of the national economy. According to statistics, China's annual coal production exceeds 3 billion tons. To improve the management efficiency of coal companies, it is necessary to monitor coal production and transportation in real-time, providing reliable data support for the coal management and operation system. Benewake's single-point LiDAR, with its compact size and low cost, can implement a networked solution for coal flow volume detection. This assists in the real-time monitoring and statistical analysis of coal loading and conveyor belt transportation.

A series of LiDAR products are installed side by side above the conveyor belt. Based on the height variations of the coal blocks obtained by the networked LiDAR during the conveyor belt operation, the system records and calculates the height variation curve, actual belt speed, and coal flow cross-sectional area. This data is then used to compute the volume and weight of the loose coal per unit of time.
1. Detection Range: 0.1-350m, adaptable to various inspection scenarios. The dual-axis servo detection angle can reach 120*120°, and the ultra-wide field of view can be adjusted according to the warehouse or material level volume. The volume measurement error is only 1%. Non-contact detection ensures no wear and long lifespan.
2. High-Frequency Detection: With a default frequency of up to 100Hz, it can detect coal flow data in real-time, providing good timeliness.
3. Cost-Effective Networked LiDAR: Using multiple single-point LiDARs in a network is cost-effective. If one device fails, the others remain unaffected, ensuring stable data.
4. High Point Cloud Density: With over 14,400 points, the measurement volume error is less than 1%. The built-in algorithm directly outputs volume values.
5. Dust Removal: Some products come with a dust removal device that periodically cleans the lens surface. The system has strong anti-interference and environmental adaptability, with added anti-static quartz glass protection against dust and dirt.
6. Easy Operation and Installation: Simple operation, easy integration, and convenient installation.
