Abstract

The disclosure relates to a system for monitoring wind influences on a working machine, such as a mobile crane or crawler crane, comprising at least one detection unit that is arranged on the working machine and by means of which a current wind speed can be detected, a recording unit that is configured to receive, to store, and to transmit data of the detection unit during and outside the operation of the working machine, a controller of the working machine that is configured to determine a current working machine state, an external processing unit that is configured to directly or indirectly receive and process data from the detection unit relating to an current wind speed and data from the controller, and an output device that is configured to receive data from the external processing unit.

First claim

The invention claimed is:

1. A system for continuously monitoring wind influences on a working machine, comprising:
at least one anemometer that is arranged on the working machine and by means of which a current wind speed can be detected;
a recording unit that is adapted to receive, to store, and to transmit data of the at least one anemometer during and outside operation of the working machine, the recording unit powered by a recording unit energy source that is separate and independent from a working machine energy source configured to provide power to the working machine for operation of the working machine, the recording unit energy source and the recording unit configured so as to receive, to store, and to transmit data of the at least one anemometer both during operation of the working machine and when the working machine energy source is out of operation or turned off, and the recording unit energy source comprising a solar cell;
a controller of the working machine that is configured to determine a current working machine state, the current working machine state comprising at least a work position and whether in the work position a boom is within or outside a payload curve range, a parked position and whether in the parked position the boom is upright or is completely placed on a ground surface, and a jack knife position and whether in the jack knife position the boom is partially placed on the ground surface, and the controller configured to determine a current working machine configuration, the current working machine configuration comprising at least boom lengths used, whether the boom is with or without a needle boom/folding tip, and a height or position of the at least one anemometer that is arranged on the working machine;
an external processing unit that is configured to receive and to process data from the anemometer relating to the current wind speed and data from the controller directly or indirectly; and
an output device that is configured to receive data from the external processing unit, wherein at least one of the controller or the external processing unit is/are configured to determine a limit value for a wind speed in dependence on the current working machine state and on the current working machine configuration;
wherein the output device is configured to, during and outside operation of the working machine, output a warning on at least one of a reaching or exceeding or impending reaching of the limit value by the current wind speed, and
wherein during and outside operation of the working machine comprises both during operation of the working machine and when the working machine energy source is out of operation or turned off.

2. The system in accordance with claim 1 , wherein an energy source is provided by means of which the recording unit is also suppliable with energy with a working machine out of operation.

3. The system in accordance with claim 1 , wherein the output device is configured to graphically present data relating to at least one of a current wind speed or the limit value or to a weather forecast or to the current working machine state or to the current configuration of the working machine.

4. The system in accordance with claim 1 , wherein the external processing unit is configured to determine with reference to a transmission interval of the data by the controller, that the working machine is out of operation and to continue to receive data from the recording unit relating to a current wind speed.

5. The system in accordance with claim 1 , wherein the external processing unit is configured to compare the data received from the recording unit relating to the current wind speed and the data received by the controller relating to the limit value with one another, with the external processing unit further being configured to use a limit value last received by the controller in operation in a time period in which the working machine is out of operation for a comparison.

6. The system in accordance with claim 3 , wherein the external processing unit is configured to receive data from the controller relating to at least one of the work position of the working machine or to the current working machine state or to the current working machine configuration or to payload values of the working machine or to limit values for wind speeds in dependence on the working machine state or to receive data from an external service relating to a weather forecast.

7. The system in accordance with claim 1 , wherein at least one sensor is provided at the working machine by means of which a parameter of the current working machine state is detectable, with the controller being configured to receive data from the at least one sensor.

8. The system in accordance with claim 1 , wherein at least one transmission unit is provided at the working machine and is configured to transmit data from at least one of the controller or from the recording unit wirelessly to the external processing unit.

9. The system in accordance with claim 1 , wherein the controller is configured to receive the data from the at least one anemometer.

10. The system in accordance with claim 3 , wherein data relating to the current configuration of at least one of the working machine or payload values or limit values for wind speeds in dependence on the working machine state or on the configuration of the working machine are stored in at least one of the controller or in a memory readable by the controller or by the external processing unit.

11. The system in accordance with claim 6 , wherein a position detection unit arranged at the working machine for the detection of the current position of the working machine is provided, with the controller being configured to receive position related data from the position detection unit.

12. The system in accordance with claim 1 , wherein the at least one anemometer is a rotatably supported cup anemometer.

13. The system in accordance with claim 1 , wherein the at least one anemometer works without an energy supply and generates a signal, with the recording unit being configured to receive this signal.

14. A working machine comprising a system for monitoring wind influences on a working machine, having:
at least one anemometer that is arranged on the working machine and by means of which a current wind speed can be detected;
a recording unit that is adapted to receive, to store, and to transmit data of the at least one anemometer during and outside operation of the working machine, the recording unit powered by a recording unit energy source that is separate and independent from a working machine energy source configured to provide power to the working machine for operation of the working machine, the recording unit energy source and the recording unit configured so as to receive, to store, and to transmit data of the at least one anemometer both during operation of the working machine and when the working machine energy source is out of operation or turned off, and the recording unit energy source comprising a solar cell;
a controller of the working machine that is configured to determine a current working machine state, the current working machine state comprising at least a work position and whether in the work position a boom is within or outside a payload curve range, a parked position and whether in the parked position the boom is upright or is completely placed on a ground surface, and a jack knife position and whether in the jack knife position the boom is partially placed on the ground surface, and the controller configured to determine a current working machine configuration, the current working machine configuration
