Crane anti-collision system solution

The intelligent cooperative battle devices installed at the construction site, training, display, checkpoint and maintenance platform have cross-working areas. To ensure the safe and efficient operation of these devices within the maintenance working area and avoid accidents and casualties caused by collisions. Rite has launched a multi-device protection system, which aims to prevent vehicle collisions in cross-working areas through intelligent means, improve on-site work efficiency, and ensure the safety of equipment and personnel.

The signal of the single manufacturing function of the radar host monitoring device is detected to see if there are any obstacles in the area space, thereby avoiding the safety of the area space between vehicles and the Internet of Vehicles due to collision signals with other objects, Bridges and surrounding objects. It will issue sound and light alarms in the safe zone and during intrusion, and even control signals from dust extraction to achieve active anti-collision monitoring and ensure the safety of the equipment.

Tower crane anti-collision system

(1) Core Technologies and System Architecture

By adopting millimeter-wave radar sensor technology and through the design of multi-transmission and multi-reception antennas, it accurately detects obstacles within 0.5 to 30 meters (the smallest can recognize a 15mm steel wire rope), and acquires distance and speed in real time
Parameters such as degree and Angle. The system is composed of a main control host, radar sensors, display terminals and networking modules, supporting CAN bus data transmission to ensure stable signals.

(2) Multi-scenario anti-collision function

Tower cranes work together to prevent collisions
By networking through a wireless bridge, the positions and movement data of multiple tower cranes can be shared in real time. A warning will be issued when the distance between two tower cranes reaches 15 to 30 meters, and an automatic shutdown command will be output when the distance is 5 to 10 meters.
Intelligent obstacle recognition
For large obstacles such as buildings, truck cranes and crawler cranes, a warning will be issued when they are 10 meters away and the machine will stop when they are 5 meters away. Support the boundary limit of the operation area to prevent the boom from intruding into risky areas such as roads and residential areas.
Adaptation to harsh environments
It has the capabilities of anti-fog, anti-dust and anti-electromagnetic interference, supports wide temperature operation from -20 ℃ to 70℃, and meets the all-weather construction requirements.

(3) System Advantages

Proactive early warning and control
Real-time sound and light alarm combined with hierarchical control (deceleration → shutdown), the operation interface supports custom parameter Settings, and is compatible with different tower crane models.
Compliance and convenience
We provide qualification guarantees such as the type test certificate of the torque limiter. The sensor adopts U-shaped clips for non-destructive installation and supports quick disassembly and reuse between construction sites.

3. Crane anti-collision system

In the operation of special lifting equipment, the overhead crane, as the core transportation tool, is exposed to complex and changeable working environments as well as high safety risks. The traditional anti-collision methods that rely on manual observation have problems such as limited field of vision and delayed response, making it difficult to deal with dynamic obstacles (such as pedestrians and equipment), which can easily lead to collision accidents and threaten personnel safety and equipment operation. With the increase in the volume of work, the demand for driving safety and intelligence is urgent, and it is imperative to achieve precise monitoring and proactive protection through technological upgrades.

This system is mainly divided into two parts: anti-collision for multiple cranes on the same track and anti-collision for cranes on upper and lower layers.

(1) Core technical architecture

Lidar scanning system

High-precision lidars (with a single coverage radius of 20 meters and an accuracy of ±2cm) are installed at both ends of the main beam. They conduct 360° hemispherical spatial scanning to collect point cloud data in real time and construct a three-dimensional space

The model accurately identifies the position, distance and movement trajectory of obstacles.

(2) Preset three-level security zones: Information zone (1m), Warning zone (0.8m), and Alarm zone (0.5m), supporting dynamic adjustment of background parameters (security password required).

Intelligent video surveillance system

Four Hikvision high-definition cameras are deployed, covering the driving track, the large vehicle operation area and the top. They support automatic zooming and switching in collision risk areas, and the video is synchronized in real time to the driver's cab display screen. The recorded video is saved for 72 hours for future reference.

Sound and light alarm and data management

Multi-level sound and light alarm

As the distance decreases, the voice prompts "Warning", "Attention" and "Stop" increase in frequency step by step. Real-time audible and visual alarm for radar failure.

Data statistics

Automatically record the alarm time, location and type, and support 15-day historical data query.

(II) System Advantages

Modular design

Compatible with the existing driving control system, it is easy to install and can be expanded for multi-radar collaborative monitoring.

Anti-interference ability

Lidar is not affected by electromagnetic interference, is suitable for complex industrial environments, and in combination with video complementarity, it reduces the impact of bad weather.

Three-dimensional visualization

The driver's cab display screen presents the three-dimensional outline of the surrounding environment and the dynamics of obstacles in real time, with blind spots clearly visible.

4. Components of the crane anti-collision system

01 Position Detection

By using various sensors such as height, amplitude and rotation sensors, the three-dimensional position information of each crane is accurately obtained. These sensors can provide real-time feedback on the dynamic changes of the equipment, ensuring the system's comprehensive perception of the environment.

02 Information Exchange System

Through the local area network communication module, tower cranes and crawler cranes can exchange position information and operation instructions in real time. This efficient data interaction mechanism ensures that all devices are updated synchronously within the same time window, reducing the risks of information delay and misjudgment.

03 Remote control processing system

As the "brain" of the system, the industrial control computer is responsible for processing data from various sensors and establishing three-dimensional models through complex algorithms. When a potential collision risk is detected, the industrial control system will immediately issue an audible and visual alarm and output a shutdown command to ensure that the equipment stops in time and prevent accidents.

04 Personnel Interaction System

The system is equipped with an intuitive operation interface. Operators can monitor the equipment status in real time, view alarm records and historical data through touch screens or remote terminals. In addition, the system also supports sending data to the server via 4G network to achieve remote management and maintenance.
