DATA RADIO TRANSMISSION AS A KEY PILLAR IN INTRALOGISTICS
Intralogistics as an organization, control, execution and optimization of the in-company material and material flow
In industry and trade, in-house material flow has gained such a high importance that in 2004 the VDMA (Verband Deutscher Maschinen- und Anlagenbau = Mechanical Engineering Industry Association) introduced the term “Intralogistics“ as a clear differentiation to logistics in the exterior such as e.g. rail and road. Intralogistics is characterized by a particularly high degree of automation of processes with usually wireless communication of transport equipment (“intelligent warehouse and storage“) associated with high demands on safety and availability in view of frequently confined and indistinct space conditions. For this reason, data radio transmission has become a key pillar of intralogistics; its ability to replace wires has decisively supported growth in intralogistics. Relevant applications are amongst others known under the terms automated guided vehicle or electric monorail conveyor.
The provision of component parts or comprehensive assembly groups (for production sequences) or objects of any kind (for shipping or warehouse processes) must be guaranteed reliably even in case of indistinct, narrow and also varying space conditions. In this process, safety and availability are the most important criteria, making high demands on control and drive technology of all intralogistics components. This includes also radio data transmission applied for wireless operation which Schildknecht AG in Murr has addressed for 35 years with high intensity. The core competence is the highest reliability of the radio link to avoid downtimes. That is achieved with the patented-registered data pre-processing technology. A very particular characteristic of this company is its business model in which the development of innovative devices and project-specific application consultancy feature the same value.
In applications like electric monorail conveyors, automated guided vehicles (AGV) or storage system the Slaves are located decentrally in cabinets.

The use of our patented filter technology guarantees a high-availability and reliable radio connection. All devices that have a Profibus DP interface can be connected by radio. Transmission speeds of up to 1.5 Mbit / s are supported.
The Dataeagle 4000 series for Wireless Profinet has been specially developed for the transparent transmission of PROFINET IO using various radio technologies. All devices that have a PROFINET IO interface can be connected by radio. The DATAEAGLE 4002 series also supports safety-related devices with PROFIsafe for PROFINET IO.
OPTIMIZED AXLE ASSEMBLY BY AUTOMATED GUIDED VEHICLES AND PROFIBUS RADIO LINKS
AGVs and the Data Transmission System DATAEAGLE 3000 Especially in engineering companies, requirements for shorter throughput times and low volumes of stock have made internal material flow indispensable. In this process, automated guided vehicles and electric monorail conveyors play an important part: here, workpieces within an assembly line are transported from one assembly station to the next one by vehicles of most different types of construction.
