Abstract

A system for detecting an object in a monitoring area with a plurality of sensors, each including a transmitter and a receiver, and an electronics unit for evaluating the receivers. The electronics unit is capable of assigning a contact address to a transmitter and/or to a receiver, wherein address assignment is effected such that after the address assignment it is possible for the electronics unit to associate receivers with transmitters.

Claims

1. A system for detecting an object in a monitoring area comprising a plurality of sensors, each comprising at least one transmitter and at least one receiver, and an electronics unit for evaluating the receivers, wherein the electronics unit assigns a contact address to at least one of a transmitter and receiver so as to allow the electronics unit to associate specific receivers with specific transmitters.

2. The system as claimed in claim 1, wherein at least one of the transmitters and receivers are arranged in separate units.

3. The system as claimed in claim 1, wherein the electronics unit selectively evaluates the receivers.

4. The system as claimed in claim 1, wherein the receivers produce a receiver-related object recognition signal.

5. The system as claimed in claim 1, wherein the electronics unit addresses the receivers sequentially for evaluation.

6. The system as claimed in claim 1, wherein the electronics unit evaluates patterns for the order in which receivers recognize an object.

7. The system as claimed in claim 1, wherein the receivers operate on the basis of light.

8. The system as claimed in claim 1, wherein the receivers operate on the basis of ultrasound.

9. The system as claimed in claim 1, wherein at least one of the receivers and transmitters are connected to one another by means of plug connectors.

10. The system as claimed in claim 1, wherein the electronics unit comprises an indicator for indicating which receiver detects an object.

11. The system as claimed in claim 1, wherein the electronics unit actuates transmitters specifically.

12. The system as claimed in claim 1, wherein at least one of the transmitters and receivers are connected to the electronics unit by means of a bus system.

13. The system as claimed in claim 1, wherein the transmitters and receivers are arranged on opposite sides of the monitoring area.

14. The system as claimed in claim 13, wherein all transmitters are arranged on one side of the monitoring area and all receivers are arranged on the other side of the monitoring area.

15. The system as claimed in claim 13, wherein, in a first transmitter/receiver pair, the transmitter is arranged on one side of the monitoring area and the receiver is arranged on the other side of the monitoring area, and in an adjacent transmitter/receiver pair, the transmitter is arranged on said other side of the monitoring area and the receiver is arranged on said one side of the monitoring area.
