The first reversible electric drive in the world was built by Siemens for a blooming train at the Georgsmarien steelworks near Osnabrück in 1906/07. It had a maximum performance of 6,800 kW.
Although the change-over to AC at the end of the 19th century brought considerable improvements, reconversion to DC was needed for many applications. The generator transformers first used for this purpose caused relatively high losses. The breakthrough came in the 1920s with the introduction of electronic rectifiers operating with mercury vapor.
In 1959, Siemens introduced the SIMATIC system of control and regulation modules based on transistorized circuits. They replaced relays, contactors and electron tubes and enabled circuits to be developed for logic, memory and computing functions.
The SINUMERIK modular system introduced in 1960 led to advances in automation in the production technology sector. SINUMERIK streamlined the positioning and linear-path control of machine tools and other production equipment.
Macao airport, constructed as a turn-key project by Siemens in a consortium with a construction company, was opened in 1996. Siemens was responsible for the power supply systems, the air traffic management systems including radar and navigation aids, the runway lighting and the building automation.
Siemens offers mining companies turn-key trolley-truck solutions for open-cast mining. The trolley-truck system consists of an overhead line, portable rectifiers and converted trucks with pantographs and hybrid engines. As a result, diesel consumption is reduced and the speed of the vehicles is increased.
Totally integrated automation is an entirely new approach to industrial automation. It enables a wide variety of technologies to be used within a single overall system with common data management.
The contract to automate the U.S. postal service, the largest enterprise of its kind in the world, involved several systems. One of their distinguishing features is extremely high speed, enabling up to 40,000 letters per hour to be sorted into the correct dispatch compartments.
Augmented Reality is an advanced technology for superimposing computer data onto real images to show 'hidden' information about all kinds of objects. For example, a portable computer inserts assembly instructions or service guidelines into the field of view of a worker wearing special 'data glasses'. The result: a combined real/virtual working environment.
In 2004, with a newly developed analysis technique, Siemens took fire detector technology an important step further. The Sinteso fire detectors have a number of sensors which are linked with intelligent evaluation technology. If, for example the curtains catch fire in a hospital ward, two separate optical and thermal sensors register smoke, heat and the particles streaming into them. The system analyses the signals, evaluates them and assesses the situation. False alarms are thus virtually excluded.
Siemens' Corex manufacturing process is making iron production much more environmentally friendly. Instead of coking coal, the normal energy source, Corex uses conventional hard coal. Corex steel mills operate without coking plants, a major source of emissions. For example, the conventional blast furnace process generates 1.4 kilograms of sulfur dioxide per ton of pig iron. According to measurements taken by TÜV Rheinland, the German technical inspection organization, Corex reduces this figure to just 40 grams while cutting dust and nitrogen oxide emissions by more than
90 percent. In addition, the gases produced in the process can be directly used for heating or generating electricity in combined cycle power plants.
At the end of 2010, Siemens introduces a new, extremely user-friendly engineering framework. The so-called Totally Integrated Automation Portal (TIA Portal) enables users to perform tasks in the automation and drives field quickly and intuitively, thus eliminating the time-consuming and costly integration of additional software packages that was previously required. Designed for high efficiency and user-friendliness, the completely redeveloped software architecture is suitable for both first-time and experienced users.
