Abstract

In order to provide rowers, when training on land, with movement and force sequences that are close to reality, through the simulation of movements and acting forces of a real boat, in particular during team rowing, the following steps are proposed: actual errors in the rowing technique on the rowing ergometer or in the rower are detected, processed and stored as data by means of parameters (6.1); correction values are calculated; and said values are input as control variables by means of a control device (6) for step-free resistance change in a damping system (5), wherein a control system that can be integrated in the rowing ergometer can thus be produced for training on land.

Description

Patent Application Method for processing training data in a rowing ergometer and

Rowing ergometer for carrying out the method

Technical Field The invention relates to a method for processing training data in one

Rowing ergometer and a rower ergometer for carrying out the method to give rower training in the countryside by simulating movements and acting forces of a real boat realistic movement and power sequences, especially for team rowing.

State of the art

The relevant experts have long recognized that training rowers a real competition adapted to the real competition concept with a rowing ergometer - too

Rowing trainer, rowing trainer or sculling trainer called - can be offered.

In a so-called Ergometerrudern movement and moment sequences must match the rowing in real rowing boats. Related settings in the rowing boat, such as the Stemmbrettposition are readily transferable in the rowing ergometer.

The rower to use in real boats and so called

Resistance is measured in known rower ergometers e.g. by flywheels with

mechanical brake or generated by electromechanical drives by means of torque output, which counteract the or the trainees.

Furthermore, software controls are known, which are the kinematics of rowing and the hydrodynamic resistance of a real rowing boat depending on his

Take into account speed, the weight of oarsmen and other oars that counteract or assist conditions. Overall, the Ergometerrudern a realistic rowing feeling by a correct simulation of all movements and moment sequences for a nearly identical

Movement feeling like being mediated on the water. Rowing ergometers can be internally or externally linked or electronically networked for training the team rudder with regard to individual movement and moment sequences in order to harmonize mutual influences and the so-called rowing technique. Since the real rowing, both the oars or belts and the entire boat, which is connected via the Stemmbrett with the rower, move, point

Rower ergometer always arranged on a frame assemblies, such as rolling seat,

Stem and handle for simulated rudders or belts. On such rower gauges, the respective rower can at least be a real boat

take appropriate sitting and working position.

Much moreover, in a rower ergometer, to simulate the complex motions and forces acting on a boat and its real, i. Through the belt or rudder generated movement in the water, assemblies are used, which should work analogous to the real conditions.

In order to solve the problem of giving the rower in the land training with the evaluations a realistic helm feel about a realistic presentation, it is therefore no longer sufficient, after e.g. US 4,396,188 A known stationary rudder units to use as rower ergometer.

On the contrary, rowing ergometers must have such determining elements as damping systems and controls or systems with feedback systems whose functions enable a realistic feeling of pulling through, similar to individual rowing and team rowing.

It is customary to use systems with e.g. Flywheel, adjustable friction mechanism such as brake and other drive means referred to as damping systems.

For this purpose, the expert knows - as well from EP 376403 Bl - largely complex designed rowing machines, which essentially a frame (frame) with a rolling seat and footrest as Stemmbrett and a via a transmission mechanism with Rudder simulation drivable flywheel with adjustable friction mechanism and

Have overrunning clutch.

According to EP 376403 Bl acting as a damping system flywheel and the adjustable friction mechanism by operative connection with the pulling of the handle, the seat and the means of the frame already meet the basic requirements of a rowing ergometer shown above, but this damping system is not controlled or regulated. For example, regarding the mandatory in a rowing ergometer Stemm board as the local footrest despite elastic arrangement has no effect on the

Damping system.

In addition, however, said rowing machine does not teach any linking functions

Team rowing.

Specifically, further damping systems for rower ergometers are known, such as

■ According to CA 2723332 AI and DE 102004051806 AI a rotary ergometer, a

Magnetic brake or a motor control, but which does not change the

Translation, high energy consumption and no energy use;

■ according to DE 102011107855 AI with purely mechanically generated resistance, which is not adjustable as a damping system;

■ According to WO 2004026412 AI a rotary ergometer with controlled hydraulic brake, which does not allow a change in the translation and no use of the energy applied by the rower. There are also control units for rowing ergometer according to CA 2723332 AI, DE 102004051806 AI and WO 2004026412 AI known. While these may provide the resistance, e.g. control in the damping system, but not adjust a required change in a required translation or even as data aufhehmbare errors in the rowing technique at the rowing ergometer or rower in the system.

In detail, also described in DE 10200405806 Al a rower ergometer to the applied by the exerciser forces with an electromechanical drive

counteract. According to this rower ergometer teaches a solution, after which the rower introduces a moment in the drive train in the fulcrum of the simulated belt. The drive train has an elastic coupling with two coupling halves. The absorbed torque is transmitted via a spring mechanism to a gearbox with servo motor or a torque motor. A change in the torque causes a relative rotation between the two coupling halves, and the torque is calculated.

Here, the control of the rower ergometer is such that a relative rotation of the coupling halves is queried and then calculated in conjunction with the kinematics of rowing, the hydrodynamic resistance of a rowing boat as a function of speed, the weight of the rower and opposing or supporting conditions, a virtual boat speed.

Thus, this device also works according to a controlled, but not a controllable robot arm, the only active compensation of

Belt vibrations taken into account.

Other designs of this rowing ergometer show the expert that, although torques of individual ergometer positions in the sense of team rudders can influence each other. Errors of posture and movement by querying e.g. the roll seat position, belt angle and height are also detected. About a torque correction can be met. The dynamic forces between the real rowboat and the oarsman can be simulated.

The disadvantage is that this control can exert on the flywheel and the rigid adjustable friction mechanism formed damping system no effect in terms of a control system.

Required joins of rowing gauges for team rowing are indeed partially disclosed in CA 2723332 AI. However, solutions for adjusting resistances according to the individual parameters of a respective rower are not proposed.

Finally, with rower ergometer feedback systems for training evaluation required and known. So reveal

■ US 20050085348 AI a feedback system as an additional device, but with no feedback on the behavior while team rudder is enabled; ■ DE 10164117 AI a feedback on horizontal movements;

■ WO 2013006145 AI feedback on the calculation of specific

Rowing errors;

■ DE 10164117 A 1 a feedback on vertical distances.

In addition to these special systems for the genus rowing ergometer, general ergometry or training arrangements have also been known as in DE 102010003344 AI. With which at least one or current vital parameters of a subject is recorded by a measuring device, stored in an electronic unit and displayed visualized on a display. Although the attribute data can be assigned to the respective vital parameter load parameter record, the requirements of the rowing sport can not be simulated realistically.

This solution presented hereafter in DE 102010003344 A1 does not provide a stimulus for solving the problem, since the vital parameters are individual and the response of the boat is independent of the individual relative load. Thus, the relative load would only be used to control training intensity but not to simulate rudder requirements. Accordingly, even such solutions for rower ergometer are not readily usable, because realistic simulations, a comparison of the vital parameters and an evaluative assignment of the applied force with the environmental parameters to an existing existing in the boat grip speed. In summary, the person skilled in the art, after analytical evaluation of the state of the art, turns out to be

■ with known rower gauges or related genera errors of a respective oarsman in rowing training are not completely recognizable on the basis of data,

■ a change in data in this regard, subject to change

Resistors at best einsteuerbar, but not nearly the characteristics of a

Control system are einregelbar and

■ thus the energy potential of a rower or a rowing crew in the

Land training is not optimally usable.

Presentation of the invention The invention is based on the object to provide a method initially described for processing training data in a rowing ergometer and a rower ergometer for performing the method, wherein the rolling seat, Stemmbrett, handle device for simulated oars or belts and damping system having ergometer means for detecting specific errors in the rowing technique both in the individual and in the

Mannschaftsrudern by capturing parameters by means of sensor data and for entering correction values to errors compared to the real rowing on the water and to change the resistance to receive such that the ergometer can be operated against previously only individually controlled correction variables with the quality of a complex control system.

According to the invention, this object is achieved with the independent claims 1 and 10. Individual features and embodiments of the invention can be found in the dependent claims 2 to 8 and 11 to 21.

Accordingly, the method includes the processing of training data in the

Rowing ergometer the new and innovative complex of steps, such as

a) Recognition of specific errors in rudder technique at the rower ergometer or rower using parameters measured as data,

b) acquisition, processing and storage of at least one parameter of data of a grip speed, seat velocity,

Flywheel speed and distribution of the mass of a rower on the rower ergometer and

Calculation of correction values for a slowing down of a boat speed caused by the faults analogous to the real rowing on the water, which are used as control variables for the change of resistance in the water

o roll seating position x _rj ,

o rolling seat speed τ ^ ₃ ,

o Boat speed at a last time «^. _j

the grip speed according to the function

ν'β, ί ⁼ S (* ^x ß, i ^jm b> ^ rt ^ st ⁱ '^ -s ^ ^ &, ΐ) is calculated, the input variables being the grip position x _g , the mass of the simulated boat m _b , the mass of the rower m _^ , the rolling seat position the rolling seat speed t ^. _s , the force on the handle F and the boat speed v _b apply, and

Grip speed data, seat velocity,

Flywheel speed and mass distribution can be entered as abstracted data of the last strokes to control the resistance in the damping system.

Here, the functions / for determining the boat speed and g for determining the grip speed of an Taylorfunktion n-th degree correspond.

Thus, by combining the above-defined functions with the respective technical functional elements of a rowing boat, the invention reveals surprising, technically-functional merging effects which create the prerequisite for a new and actually realistic concept for landlaining.

In essential embodiment of these steps according to the invention is by means of

Control _device from recorded data an actual grip speed Vg, - ^ compared with a calculated _{grip speed} according to the relationship> v ^ _saU and calculated, after which a greater or lesser resistance is entered as a controlled variable in the damping system.

With several rowing gauges as for a rowing crew, the inputs of all oarsmen become according to the relationship calculated and recorded by the control device, processed and adjusted.

It will be the input variables

a) the grip position x _e by a sensor,

b) the mass of the simulated boat m _b corresponding to the real boat,

c) the mass (weight) of the rower corresponding to the real value,

d) the rolling position ae _ra and

e) the seat speed v ^. _s through a sensor,

f) the acting force F on the gripping device and

g) the boat speed at the last time u ^ -n

detected by the control device, processed and in the damping system

entered. The method involves the use of a CVT continuously variable transmission

Resistance change in the damping system. It is practically simply completed by the use of a CVT gearbox associated with the stepping motor, in which a larger or smaller translation factor can be entered as a controlled variable in very small steps control.

The use of a program integrated in the control device with at least one of the program steps, such as

a) recording, processing, storing and outputting of the data for calculation of the boat speed and calculation of the grip speed, b) recording, processing, storage and output of all data from

Parameters of the grip speed, roll seat speed, flywheel speed, distribution of the mass of a rower as abstracted data of the last strokes and

c) input of the data in the damping system by means of the control device further forms the method as a control system in view of a high degree of automation.

The method allows the application as storage of the respective rower assigned, designated here "athlete's technique data set" in the

Control device simulating a virtual boat with a concrete oarsman. Thus The rowing style of a rower can be quasi described by means of said data set and read by another rower on the ergometer and the virtual boat can be simulated with a concrete rower. Absent or pausing rowers are meanwhile simulated by means of the "athlete technique data set" and their

Performance parameters compared. Thus, the "athlete's technique data set" can be used to determine which oarsmen are also to be selected for a crew in real rowing on the water, for example, to enable the fastest rowing.

In accordance with this method, the rower ergometer is conventionally provided with a rolling seat, a stiffening board, a simulated rudder or belt gripping device, a variable speed flywheel damping system, but also with a regulating device and a feedback system, with which regulating device one boat speed at a time i according to the function * and a grip speed according to the function ^v s ° i are calculable and data of parameters of

Gripping speed, roll seat speed, flywheel speed, distribution of the mass as abstracted data of the last oars strikes are entered into the damping system. The control means makes it possible to compare and calculate the actual grip speed with a calculated grip speed vr ^ s ^ n according to the relationship> v _{afio &} after which a greater or lesser resistance can be input as a controlled variable into the damping system. The control device secures at the same time at several rower ergometers for a

Rowing team that the inputs of all oarsmen according to the relationship

,

calculable and can be entered in the damping system.

Furthermore, the rower ergometer for data acquisition has a sensor as

Handle position indicator and a sensor as a rolling seat position indicator. The damping system is associated with a CVT transmission for stepless resistance change and a stepping motor for setting a variable transmission factor, wherein the control device, the cyclic adjustment of the stepping motor is effected. Thus, the damping system realizes the procedure according to the regulation in very small steps control input resistance change in a practically simple design.

The networking of several rower ergometers is easily possible.

With a built-in remote control in the grip device also a manual influence on the resistance change in the damping system is ensured.

A graphical output of the acquired, processed, stored and input data which can be executed as a display forms the feedback system with the regulating device. The invention also makes it possible to use a simple or conventional rowing ergometer, comprising only a rolling seat, stalking board, gripping device and damping system, by means of an equipment set comprising one or more assemblies combined into a functional unit, such as

a) continuously variable CVT transmission with the variable ratio factor

adjustable stepper motor,

b) Control device with integrated program and connections for the

Recording and entering the parameters,

c) in the grip device integrated remote control and

d) display executable graphic output,

may include to use according to the invention.

With the method and the subsequently developed ergometer, the invention of known generic rowing ergometers stands out by the following criteria:

One of the task corresponding

■ Recognition of concrete errors in the rowing technique based on sensor data on the rower ergometer or on the rower by data of the grip speed,

Roll seat speed, flywheel speed, to determine the mass distribution and calculation of a feedback and a calculation of the theoretically caused by this error slowing down on the water in real rowing and

■ Resistance change for a rowing ergometer through a stepless

Resistance change between e.g. conventional train as an arm of the rower rudder force-transmitting element and flywheel during a

Rudder impact, whereby the flywheel can be damped at will, e.g. also by windmill or magnetic brake.

2. A jump in quality to a regulation of the resistance change by using the data recorded by sensors for errors to be processed, wherein

■ by networking with several rower ergometers the adjustment of the data is made possible, equally dependent on the data of these rower ergometers as well as the recorded parameters of the rower, and

■ a calculation of the displayed on the graphic output (display)

rudder speed

with the aid of the weight of the rower using the measured values recorded by weight sensors,

- taking into account the water displacement simulated on the water and

- if the abovementioned boat decelerations are deducted, which are not automatically simulated by the mechanics of the rower ergometer,

can be done.

Compared to the detailed interpretation of the prior art is to be emphasized that with the invention by the simulation of exact, realistic motion and

Momentary movements a nearly identical movement feeling as on the water only by the described control system and the simulation of different crew boats is made possible. Thus, the invention is also characterized by the fact that one or more rudders are missing and can be simulated by the control system. The simulation of powerful rowers - e.g. from a real national selection eighth - causes other rowers to adapt to their performance.

Thus, the possibility exists in competition mode against real or simulated

Challenger in single or crew boat to compete. Performances of different oarsmen are summarized for the first time around a realistic model of the

Represent boat speed. The performance of several rowers is not but added up according to the performance increase in real rowing by several rowers calculated and regulated.

The invention also makes it possible to simulate environmental conditions such as headwind and currents to various training and challenge scenarios and to integrate relevant parameters in the control system.

Bearing in mind this potential of processing and control of technical, bionic and environmental parameters in a rower ergometer according to the invention, this can partially or completely take over a tramer function, on the other hand in this regard

Spare admissions.

In general, the ergometer can also be used for strength exercises, in particular for the row-typical arm pull, for which the resistance is dynamically optimally adjustable.
