High-precision sensors for optimal intralogistics

Automated guided vehicles (AGVs) perform a key function in Industry 4.0 applications in the smart factory: They connect production lines with each other to boost the efficiency of intralogistics processes. However, this requires that the vehicles reach their destination safely and via the shortest route. High-precision inertial sensors from ASC enable reliable vehicle dynamics as well as precise navigation of AGVs to ensure the smooth flow of materials.
Applications in the logistics industry
The volume of worldwide freight transport is constantly growing, together with the demand for special vehicles to transport the containers in the harbor. The transport of the containers is performed primarily by AGVs (automated guided vehicles), which are controlled by a control center. Such automation is technologically very complex and requires maximum precision.

Without modular material supply systems the factory of the future would be inconceivable. Highly automated equipment plays a key function in optimizing internal logistics processes. Goods receipt and dispatch, warehousing, order picking and transport itself are increasingly controlled by digital technologies.

Automated guided vehicles for example enable the goods-to-person principle, which increases the efficiency of material deliveries for modern production lines.

Robots and cobots perform the loading and unloading processes, making material flow safer and more ergonomic. Functional safety and structural durability must be ensured at all times

Monitoring of inertial measurements such as angular rates and acceleration is therefore important in assessing the reliability of intralogistics processes.

Automated guided vehicles must be designed so that they do not endanger employees, other AGVs or machines and systems.

Whether analog or digital: Inertial measurement units (IMUs) from ASC continuously detect the position and motion of objects with high precision. For high-precision position measurement, the analog ASC IMU 8 and the digital IMUs HG4930 and HGuide i300 from Honeywell are the ideal solution.

The analog IMUs allow maximum freedom in the processing of data and a modular concept for optimal application-specific configuration. The digital versions are especially suited for test applications, since they feature numerous pre-configured settings for fast start-up with the Honeywell HGuide data reader software.

In addition, the HGuide Navigators n580 and n380 are designed for the integration of GNSS signals such as GPS, GLONASS, BeiDou or Galileo by means of SBAS, PPK, RTK, single or double antennas.

In order for automated guided vehicles to navigate reliably to their destination, they must be equipped with inertial sensors. The more flexible the route regarding the degrees of freedom of motion, the more powerful the sensor system has to be, since the requirements for safety, detection of the environment and localization of the AGV are more complex.

Especially suitable for automated guided vehicles are the compact gyroscopes ASC 271 and ASC 273 as well as the ASC IMU 7. The uniaxial and triaxial gyroscopes detect angular rate of the vehicles, which makes them ideal for optimization of curve speed.

If linear components also have to be monitored – such as in the control of vehicle behavior during acceleration and braking – the ASC IMU 7 is recommended.
