Munich, Germany - EnOcean launched its Dolphin system architecture at electronica 2008. It enables energy-autonomous actuators, bidirectional communication of sensors and innovative routing concepts. The new architecture allows on-demand matching and continuous optimisation of central system features such as energy budget, peripheral functionalities and wireless communication. The length of wireless telegrams, for example, is minimised dynamically to the data content for transmission, and in programming only those software function blocks actually needed by the user are saved to memory.
EnOcean technology is already being used to wirelessly link hundreds of thousands of energy-autonomous sensors in buildings worldwide. The Dolphin architecture was developed to enable non-proprietary systems to match the increasing demands of very different applications, and grow in their functionality together with the demands of such applications. The launch of the platform marks an entry into new industrial control and automation systems, an expansion of existing applications to save energy, to enhance comfort, convenience and security, for access control and consumption data metering in building services. Dolphin system architecture, through its modularity, is suited for future demands such as encryption or meshNet routing.
STM 300 and TCM 300 modules for bidirectional sensor communication
New modules based on the Dolphin system architecture enable bidirectional communication of energy-autonomous sensors. The bidirectional plug&play TCM 300 transceiver module for wireless systems has half the standby power requirement compared to its predecessor (2.5 to 3.3V, receiving approximately 30mA and transmitting approximately 15mA) cutting the costs for the power supply and reducing power consumption by around 50%.
Compared to its forerunner, the 10-bit A/D converter produces greater measuring accuracy and four times the resolution for sensors. An optional repeater function, activated by a pin, reduces the number of system components needed and simplifies start-up. The mini operating system and new API enable straightforward programming of applications. Parameters can be changed using software updates during installation or in operation.
Complex software functions such as SMART ACK (bidirectional wireless transmission), encryption and routing can be integrated as ready macros, maintaining the interoperability of end-user equipment and shortening time to market. The module offers a number of ready programmed operating modes for switching and dimming. A bidirectional serial interface serves for integration in external logic or an automation system.
The STM 300 is the bidirectional module for energy-autonomous device applications. It differs from the TCM 300 through its extensive energy management of miniature converters which harvest energy from differences in temperature, rotation, light or vibration. Central parts of the integrated circuit are the ultra-low-power wake-up, threshold switch and voltage limiter. Like its predecessor, the new module has a number of basic plug&play operating functions removing the need to program STM before start-up. These functions are three analogue inputs, four digital inputs, configurable wake and presence cycles and wake-up pins.
The Dolphin system architecture, together with the new TCM 300 and STM 300 modules, is next generation EnOcean system architecture, and is fully backward compatible with earlier products and installations. In addition to the introduction of new platform the company has also further developed its wireless standard and has created new space for innovative non-proprietary solutions. Dolphin is a technical system platform for worldwide standardisation because it ensures interoperability, backward compatibility and maximum flexibility well into the future.
