The invention presents a method and a device for bidirectional IR data transfer between a medical treatment table, particularly an operating table (10a to 10d), and an operator control device (12a to 12d) which are subscribers in the IR data transfer and which each comprise an IR transmitter and an
The invention presents a method and a device for bidirectional IR data transfer between a medical treatment table, particularly an operating table (10a to 10d), and an operator control device (12a to 12d) which are subscribers in the IR data transfer and which each comprise an IR transmitter and an IR receiver, where the data to be transferred by a subscriber (10a to 10d, 12a to 12d) are split into data blocks which are transmitted in succession, with a respective break being observed between the transmission of the individual data blocks, and where data from another subscriber are transmitted within the breaks.

1. A method for bidirectional IR data transfer between a medical treatment table and an operator control device which are subscribers in the IR data transfer and each comprise an IR transmitter and an IR receiver, wherein the data to be transferred by a subscriber are split into data blocks which are transmitted in succession, with a respective break being observed between the transmission of the individual data blocks,wherein data from another subscriber are transmitted within the breaks,wherein the transmission of a data block is preceded by a check to determine whether IR signals are present and is held until a predetermined waiting time has elapsed after the disappearance of the IR signal if IR signals are present,wherein the subscribers receive their transmitted signal themselves, check their transmitted signal, and retransmit the associated data if the signal has been disturbed,wherein the predetermined waiting time is selected at random, andwherein the predetermined waiting time for the operator control device is shorter than the predetermined waiting time for the medical treatment table. 2. The method according to claim 1, wherein a plurality of medical treatment tables and associated operator control devices having at least partly overlapping IR signal reception ranges are provided, and wherein each of the subscribers is allocated a different waiting time. 3. The method according to claim 1, in which the carrier frequency for the IR signals is more than 120 kHz. 4. The method according to claim 1, in which each data block contains an identification code which is associated with a subscriber, and in which each subscriber identifies from the identification code whether the data block is intended for it. 5. The method according to claim 1, in which the signal length of a data block is between 1 ms and 50 ms. 6. The method according to claim 1, in which the break between the transmission of two data blocks by the same subscriber is 5 to 50 times the signal length of a data block. 7. The method according to claim 1, in which the data to be transferred from the operator control device to the medical treatment table relate to adjustment commands for adjusting the bearing surface of the medical treatment table. 8. The method according to claim 1, in which the data to be transferred from the medical treatment table to the operator control device relate to one or more of the following states of the medical treatment table: the current attitude and position of the bearing surface, the arrival at stored attitudes and positions of the bearing surface, error messages, information about functions which are not possible, connection to the power supply, the charge state of storage batteries, and a warning about a collision between the medical treatment table and accessories. 9. The method according to claim 1, in which the operator control device is formed by a portable, hand-held remote control, by a footswitch or by a wall-mounted remote control. 10. The method according to claim 9, in which the operator control device has a display. 11. A device for bidirectional IR data transfer between a medical treatment table and an operator control device, having a first IR data transfer unit which is arranged in the treatment table and which comprises an IR transmitter and an IR receiver, and having a second IR data transfer unit which is arranged in the operator control device and which comprises an IR transmitter and an IR receiver, in which the first and/or the second IR data transfer unit is programmed such that it splits data which are to be transferred into data blocks and transmits them in succession to the second or first data transfer unit, wherein it observes a respective break between the transmission of the individual data blocks and where the second or first data transfer unit is programmed to transmit data to the first or second data transfer unit within the breaks,wherein the first and/or the second IR data transfer unit is programmed such that it checks whether IR signals are currently present, and if IR signals are present, then it holds transmission of the data block until a predetermined waiting time has elapsed until the disappearance of the IR signal,wherein the first and/or the second IR data transfer unit is programmed such that it receives its transmitted IR signal itself, checks it and, if the signal has been disturbed, retransmits the associated data,wherein the predetermined waiting time is selected at random, andwherein the predetermined waiting time for the operator control device is shorter than the predetermined waiting time for the medical treatment table. 12. The device according to claim 11, which is suitable for carrying out a method.
