DHR NLS3000 NLC System (Navigation Control System)

Product basic positioning and core functions

1. Product positioning

The NLS3000 NLC System is a high-precision real-time navigation and positioning control system, designed for devices that require precise position monitoring, path planning, and dynamic control. Typical applications include:

Port terminal: positioning and path correction of container cranes (shore bridges, yard bridges);

Industrial scenario: Autonomous navigation of heavy-duty transport vehicles (AGVs), position synchronization of track mounted equipment;

Maritime assistance: guidance for small ships to dock and fixing the position of water operation platforms.

The system supports multi-sensor fusion and can be combined with GPS, LiDAR, encoders and other devices to improve positioning accuracy, in compliance with EU CE certification and industrial equipment electromagnetic compatibility (EMC) standards.

2. Core functions

Specific Capability Value Explanation for Functional Categories

High precision positioning static positioning accuracy ± 5mm (close range laser assistance), dynamic positioning accuracy ± 10mm (speed ≤ 5m/s); Support switching between absolute coordinates (latitude and longitude) and relative coordinates (device local coordinate system) to meet the strict requirements of high-precision operations for position errors, avoiding accidents caused by equipment collisions or positioning deviations

Path planning and control support preset path storage (up to 100 custom paths) and real-time path correction (response delay<100ms); It is possible to set a "prohibited area" (electronic fence), which will automatically slow down/stop when triggered to reduce manual operation intensity, lower the risk of misoperation, and adapt to multi scene operation processes

Data collection and communication: Real time collection of position, velocity, attitude (inclination, heading) data, with a sampling frequency of 100Hz; supports industrial communication protocols such as RS485, EtherNet/IP, Profinet, etc., and can be connected to the upper computer (SCADA system) to achieve remote monitoring of equipment status, facilitating production scheduling and data tracing

Fault diagnosis and alarm built-in sensor fault detection (such as GPS signal loss, LiDAR obstruction), communication interruption alarm; Support fault code storage (up to 50 historical fault records), with sound and light alarm prompts to shorten troubleshooting time and improve system reliability

System composition and hardware architecture

1. List of core components

The NLS3000 NLC System is designed with modularity, and the standard configuration includes the following components, which can be added or removed according to the application scenario:

Component Name, Model/Specification, Function and Function

The main controller NLC-3000-MC system core is responsible for data computation, path planning, and device control, with a built-in Linux real-time operating system

Positioning sensor module - GPS receiver: NLC-GPS-01 (supports Beidou/GLONASS dual-mode, positioning update rate 10Hz)

-Lidar: NLC-LIDAR-20 (measuring distance 0.5-20m, accuracy ± 2mm)

-Incremental encoder: NLC-ENC-1024 (resolution 1024 lines/rev, adapted to wheels or tracks) multi-sensor fusion, ensuring positioning accuracy in different environments (such as indoor/obstructed areas with weak GPS signals)

Display and operation unit NLC-HMI-10 10 10 inch touch screen (resolution 1280 × 800), supporting parameter settings, real-time status display, and fault inquiry; Equipped with a physical emergency stop button human-machine interaction interface, convenient for on-site operation and status monitoring

The NLC-IO-16 execution control module has 16 digital inputs/outputs (DI/DO) and 4 analog inputs (AI, 0-10V/4-20mA), used to connect motor drivers, solenoid valves, and other actuators to achieve dynamic control of equipment by the controller (such as speed regulation, steering, braking)

The power module NLC-PWR-24 has an input voltage of 110-240V AC and an output of 24V DC/5A. It is equipped with overvoltage and overcurrent protection to provide stable power supply for various components of the system and is suitable for different on-site power conditions

2. Hardware architecture logic

The system adopts a "layered control" architecture, and the data flow is as follows:

Perception layer: GPS, LiDAR, encoder and other sensors collect position and motion data and transmit it to the main controller;

Control layer: The main controller performs fusion operations on data, generates control instructions based on preset paths and real-time status;

Execution layer: The execution control module receives instructions, drives the motor, brake and other execution mechanisms, and feeds back the execution status to the main controller;

Monitoring layer: HMI and upper computer receive status data sent by the main controller, realizing display, alarm and remote operation.
