Abstract

The invention relates to a maintenance system for a control device (1) of hydrostatic drives. Said system comprises a control unit (16) and a first interface (12a) that is connected to the control device (1) via a data line (6a), for the bi-directional transfer of data and a maintenance device (3) comprising a second interface (12b) that is connected to the maintenance device (3) via a data line (6b), for the bi-directional transfer of data. The first and the second interface (12a, 12b) have a respective transceiver (4a, 4b) and an antenna (5a, 5b) and data is transferred between the control device (1) and the maintenance device (3) in a wireless manner by radio.

Claims

1. Maintenance system for a control device (1) of hydrostatic drives with a first interface (12a) for bi-directional data transmission connected via a data line (6a) with a control unit (16) of the control device (1), and a maintenance device (3) with a second interface (12b) for bi-directional data transmission connected via a data line (6b) with the maintenance device, characterised in that the first and second interfaces (12a, 12b) each have a transmitter/receiver (4a, 4b) and an antenna (5a, 5b) and the data transmission between the first and the second interfaces (12a, 12b) takes place wireless by radio.

2. Maintenance system according to claim 1, characterised in that the first transmitter/receiver (4a) is arranged in the control device (1).

3. Maintenance system according to claim 1 or 2, characterised in that the second transmitter/receiver (4b) is arranged in the maintenance device (3).

4. Maintenance system according to claim 2, characterised in that the antenna (5a) is arranged in the housing of the control device (1).

5. Maintenance system according to claim 3, characterised in that the antenna (5b) is arranged in the housing of the maintenance device (3).

6. Maintenance system according to any of claims 1 to 5, characterised in that the first interface is an RS 232 or a CAN-bus interface.
