Embodiment Construction

[0012] Different implementations are possible for this:

[0013] The interface circuit can contain a very low-power and inexpensive microcontroller with non-volatile memory.

[0014] However, the interface circuit can also be implemented by means of FPGA (Field Programmable Gate Array) logic circuits with corresponding memories.

[0015] The interface circuit is programmed by the controller of the working device. In a preferred embodiment, the interface circuit is galvanically separated from the operating device. In principle, unidirectional or bidirectional communication is possible by means of galvanic separation. Here, not only the parameters and addresses of the digital interface can be sent to the interface circuit, but also operating parameters such as the operating hours of the device, the burning duration of the connected lamp and the maximum temperature occurring during the operating time to date . It is also possible to store internal fault states which, in the e...

Abstract

The invention relates to a circuit arrangement for mirroring parameter sets for operating devices of digitally controlled lighting systems, comprising at least one control input and one control output for controlling the operating device that is connected to the circuit arrangement, the circuit arrangement being configured for control by a digital control unit and having a memory component, which stores the address assigned to the operating device and the programmable parameters and / or individual device parameters, and said data being able to be read by an external service device, or data from an external service device being able to be stored in the memory of the circuit arrangement according to the invention.

Description

technical field [0001] The invention relates to work machines with digitally controlled inputs, which are driven by a numerical control in lighting devices. [0002] A very widely used digital lighting control protocol is the so-called DALI protocol. DALI stands for Digital Addressable Lighting Interface and is a control protocol for controlling working devices of digital lighting technology in buildings such as electronic transformers, EVG (electronic ballasts), electronic power dimmers, etc. Each working device with a DALI interface can be activated individually via a DALI short address. The DALI control device or the DALI gateway can interrogate the state of the luminaire or the operating device of the illuminant and set a status by means of a bidirectional data exchange. DALI can be operated as an "island system" with up to 64 operating devices or as a subsystem via DALI gateways in modern building automation systems. DALI uses a serial asynchronous data protocol with a...
