KNX controller is designed for building automation which adopts a standardized (EN 50090, ISO/IEC 14543), OSI-based network communications protocol. KNX is the successor to, and convergence of, three previous standards: the European Home Systems Protocol (EHS), BatiBUS, and the European Installation Bus (EIB or Instabus). The KNX standard is administered by the KNX Association.
The standard is based on the communication stack of EIB but enlarged with the physical layers, configuration modes and application experience of BatiBUS and EHS.
KNX is designed to be independent of any particular hardware platform. A KNX Device Network can be controlled by anything from an 8-bit microcontroller to a PC, according to the needs of a particular implementation. The most common form of installation is over twisted pair medium.
The KNX system includes sensors that send telegrams, actuators that receive telegrams and KNX bus that connects the sensors and actuators and transmits telegrams.
All the devices for a KNX installation are connected together by a two wire bus (the most common form of installation), thus allowing them to exchange data. The function of the individual bus devices is determined by their project planning, which can be changed and adapted at any time.
Sensors are the starting point for every action, because they gather information and send it on the bus as a data telegram. This can be information about room temperatures, movements, wind measurements or manually input instructions (Push buttons). Sensors are selected depending on the required application.
Actuators receive data telegrams which are then converted into actions. This can include controlling blinds, dimming lights or controlling heating and air conditioning systems. Actuators are also selected depending on the required application and consist of a bus coupler and an application module with the corresponding application program.
The application program is loaded into the devices together with the project design and commissioning software via a system component called interface (either serial or USB interface) connected to the PC and the bus. The two-wire installation bus is routed in parallel to the 230 V electrical power supply connects all devices and systems of the household technology together, and transmits all the control signals. It looks the same as the DALI protocol bus.
KNX controller can be configured to switch and dim LED lighting, and many more functions can be configured to the controllers:
3D Moon Lamp for Creating Right Atmospheres
Lighting is a very important aspect for creating right atmospheres for dating, parties and holidays. Compared to traditional lighting design, 3D Moon Lamp is a more flexible and portable LED moon lamp that adopts LED light source and is powered by rechargeable battery.
FDM 3D Printer Widely Used for Prototyping and Concept Model Building
Fused Deposition Modeling builds concept models, functional prototypes and end-use parts in standard, engineering-grade and high-performance thermoplastics. It’s the only professional 3D printing technology that uses production-grade thermoplastics, so parts are unrivaled in mechanical, thermal and chemical strength.
DLP 3D Printer To Print High Precision Objects With Ultra Smooth Surface
DLP stands for digital light processing that is one of the popular technologies used for 3D printing. Unlike FDM technology, this technology uses light from projectors to turn liquid resin into a solid object, one layer at a time and accumulates layer by layer finally to form an object.
