Abstract
A bus system, a shelf edge strip bus system in particular, which comprises a first line for determining an electric reference potential, a second line for providing a supply voltage with a desired value in relation to the reference potential, at least one third line, preferably a single third line, for communication of signals and/or data, a supply device, which is electrically conductively connected to the lines and is designed for electric power supply as well as for communication supply of electronic devices which can be connected to the bus system, wherein the supply device is designed to supply different device types both with electric power and with communication, particularly in a device-type-specific manner.
Claims23
A bus system, comprising:
- a first line for determining an electric reference potential,
- a second line for providing a supply voltage with a desired value in relation to the reference potential,
- at least one third line for communication of signals and/or data,
- a supply device, which is electrically conductively connected to the first line, the second line and the at least one third line, and is designed for electric power supply as well as for communication supply of electronic devices which can be connected to the bus system,
- wherein the supply device is designed to supply different device types both with electric power and, following identification of the device type, with communication in a device-type-specific manner,
- wherein the supply device is designed for a temporary change of the supply voltage in order to introduce a change of an operating mode of the supply device, and
- wherein the supply device comprises a detection mode, in which the supply device is designed for detecting identification data, which uniquely identify an electronic device which is connected to the bus system, of one or more electronic devices which are connected to the first line, the second line and the third line, and the supply device is designed to assume the detection mode for the purpose of introducing the change of the operating mode of the supply device.
An electronic device, which electronic device comprises a bus interface designed for connection to lines of a bus system, wherein
- the bus system comprises:
- a first line for determining an electric reference potential,
- a second line for providing a supply voltage in relation to the reference potential,
- at least one third line for communication of signals and/or data,
- a supply device, which is electrically conductively connected to the first line, the second line, and the at least one third line, and is designed for electric power supply as well as for communication supply of other electronic devices which can be connected to the bus system,
- wherein the electronic device is designed for the identification of the electronic device with respect to the supply device for the purpose of subsequent device-type-specific communication with the supply device,
- wherein the electronic device comprises a detection stage which is designed for detecting a temporary change of the supply voltage, wherein the electronic device is designed to change its operating mode in the event of such a detection,
- wherein the electronic device comprises identification data which are used for the unique identification of the electronic device,
- wherein the electronic device comprises an identification mode in which the electronic device is configured for delivering the identification data via the at least one third line, and
- wherein the electronic device is designed for assuming the identification mode for the purpose of changing an operating mode of the electronic device.
