Abstract
Disclosed are a method and a device for supplying electrical power for two or more technical systems, which are connected to an electrical supply line with a feed point, arranged in a connecting rod, and for data transmission between the feed point and the technical systems, supplying power to the technical systems is done with essentially constant current intensity. Data transmission from the feed point to the technical systems is done by modulating the current intensity, and data transmission from the technical systems to the feed point is done by modulating the voltage.
Claims16
A method for supplying electrical power for two or more technical systems, which are connected to an electrical supply line with a feed point, arranged in a connecting rod, and for transmitting data between the feed point and the two or more technical systems, the method comprising:
- supplying the electrical power to the two or more technical systems with essentially constant current intensity;
- and
- said transmitting the data from the feed point to the two or more technical systems by modulating the essentially constant current intensity,
- wherein said transmitting the data from the two or more technical systems to the feed point is done by modulating a voltage in the two or more technical systems,
- wherein a fed of the essentially constant current intensity is electronically limited to a maximum permissible short-circuit current, and
- wherein the voltage present at at least one of the two or more technical systems is defined by a constant-voltage two-terminal device on the electrical supply line.
A device for supplying electrical power for two or more technical systems, which are connected to an electrical supply line with a feed point, arranged in a connecting rod, and for data transmission between the feed point and the two or more technical systems, the device comprising:
- a constant-current source configured to supply the electrical power to the two or more technical systems;
- a current intensity modulation system configured to modulate a current intensity for the data transmission from the feed point to the two or more technical systems;
- a voltage modulation system configured to modulate a voltage in the two or more technical systems for the data transmission from the two or more technical systems to the feed point;
- and
- an electronic system in order to limit a fed of the current intensity to a maximum permissible short-circuit current,
- wherein the voltage present at at least one of the two or more technical systems is defined by a constant-voltage two-terminal device on the electrical supply line.
