DRIVE TECHNOLOGIES 02 Visual PowerPack The creature in action This video shows the dragonhorse „walking“ through the city of Nantes, France. required lifetime and the constraints in terms of use and availability into account, Dintec selected Sodium Nickel batteries for their high power and energy density and supplied 5 sets of 23.56 kWh each fitting to the 620Vdc net and weighing a total of 1,000 kg. While each set features its own cooling system, the batteries are designed to be charged from the grid but can also be directly charged from the embedded PowerPack when necessary. Animating such an animal smoothly and realistically means over 50 speed and position regulations for the movements of the head, the body, the legs and the displacement (hydraulic propelling and steering). To handle these numerous functions and also the communication between the 24 HMI (display, joysticks, keypads) and more than 200 sensors (angles, length for cylinder heads, pressures, temperatures, etc.), Dintec defined a complex network of 16 embedded controllers communicating through 17 different CAN-buses. The STW ESX-3XL was selected as the central control unit and brain of the system. The ESX-3XL can handle up to 124 I/Os and offers plenty of computing power and memory to run the sophisticated application. The steering and propelling get managed through the off-the-shelf STW ESX-C which is fully capable of controlling the rolling chassis. Dintec used the ESX-C to implement the power management algorithms. These are capable of adjusting permanently the power generation to the machine requirements and make sure all requested movements can be operated at the right speed. Two ESX-IOX and eleven ESX-IOXp decentral I/O control systems for the hydraulic movement control of the head, legs, and eyes were deployed by Dintec. Also, efficient communication between all CAN participants was established. At last, a STW ESX-C2C with mobile communication capabilities was added so that diagnosis, software updates and machine follow-up was possible remotely using Dintec’s wellproven web server. Unforgettable moments After intensive testing in Nantes, France, Long-Ma passed all controls and certifications handled by TUV Belgium which is specialized in unusual and therefore special applications. Long-Ma then left Nantes in September 2014 aboard an Antonov 124 to land the next day in Beijing, China. After being re-assembled and after several days of testing and Long Ma Jing Shen, Original creation of François Delaroziere & Cie La Machine as part of France China 50 and supported by Institut Français. rehearsals for the ceremony, Long-Ma performed 3 days of intensive shows, leaving unforgettable memories to the Chinese public. Finally, Long-Ma returned back to Nantes in June 2015 for a couple of presentations and performances. After those Long-Ma is due to be permanently located in China as part of a larger project. Both companies, Dintec as the system integrator and STW as the provider of the control system, the power generation and motors were proud to work on a project of this scale. This pride reached its peak when after 12 months the engineered system gave life to the animal which took part in the big show for the celebrations of the 50 th anniversary of China’s and France’s diplomatic relations. This project could be realized on time only due to the long term relationship between Dintec and STW. Only this way the requirements of the machine manufacturer could be met as all technical challenges could be solved by seamless communication. Dintec’s deep know-how in electrification and electrohydraulic systems combined with the quality of the STW components once again achieved customer satisfaction.
