Tempodicting device, in particular for guiding the competitors in cyclic sports

Field of application of the invention :

The invention relates to a tempodiktierende device, in particular for guiding the competitors in cyclic sports in which the competition result (also) is measured as time.

Characteristic of the known technical n 'solutions:

In all so-called cyclical sports, especially swimming, running, cycling, rowing, paddling, canoeing and, indirectly, equestrian sports, the information about the time results of the entire route and the part-time is extremely important. "This information is partly in competition conditions prescribed, in addition to which they promote the scientific

speed and effectiveness of training and training. The emphasis on even force development is a fundamental category in the theory of training. It has been scientifically proven that the competitor's energy consumption is proportional to the square of the plus speed reached in sections. The correct tempo, the regulation of the movements can be learned - the device according to the invention has the purpose of promoting the practice and acquisition of the correct tempo. The device acts practically like a tempo generator, at the leadership pace of which several independent parameters (real-.data and 'plan data) have an influence, and whose' leadership speed - transmitted to the athlete - influences the actual speed of the athlete's movement. The restoration of the normal biological rhythm is also indicated by the re-establishing accuracy of the sense of time. This is important for the biorhythm shifts that occur in acclimatization when traveling in east-west direction. By appropriate experiments with the device according to the invention can thus be determined when the disturbed because of the time lag biological balance has re-established. Maximum training loads can only be tolerated in the state of biological balance.

The course of the cyclical time results has been analyzed for a long time in many sports branches, and for some time different means have been used to influence the tempo of the competitor in the meanwhile (during the competition) and by technical means of control a subsequent evaluation or a partial analysis of the course of the competition to enable.

In the individual competitions or between their sections, local measurements are made (for example

with a device measured down to the swimming pool, the instantaneous pulse is measured), the result of the cooling is fixed and then compared with the result of the competition, the correlations are evaluated.

Purely the leadership of athletes during training has recently begun the spread of two modern coats. The one is a central transmitting device whose signals receive a attached to the body of the athlete, perceptible to the athlete signals emitting personal receiver, whereby the athlete can receive certain signals in the meantime. These devices work. ¹ in general in single-channel operation, but there is no technical obstacle to the fact that the central transmitting system transmits simultaneously over several channels and the personal receivers of the individual athletes each receive only the signals of its own channel.

• Another method of guidance is that, for example along the swim signal means (for example, lamps) are arranged, and according to the pace prescribed by the coach always glow those lamps indicating the speed of locomotion on the lying directly in front of the athlete stretch ,

By using this remedy it was possible to increase the effectiveness of the training, but only to a limited extent. When guided by light signals was undoubtedly advantageous that with relatively little distraction of attention the swimmer information could be transmitted, whose appearance also instinctively suggested the prescribed pace, nevertheless, the attention of the athlete had to be distracted to some extent. Also, the actual reaction of the organism was not always optimal, considering the condition of the organism of the athlete,

only subsequently evaluable data with. compared to the prescribed pace and the actual result.

Object of the invention:

The aim of the invention is to provide a device with which to be unfolded in a unit time effort of participating in a competition athlete on the individual cycles of the entire competition optimally set v / ground, the peculiarities of each sport and the individual disposition of the athlete . can be taken into account.

presentation; the essence of the invention;

Basis of the invention is the recognition that by combining the mentioned as well as other technical means, a guide mechanism can be created, which allows the creation of a closed (two-sided) control chain instead of the previously applied unilateral 'leadership in the connection between coaches and athletes .. Bei the known guidance methods were sent information from a central transmitter - or indicated via lines through the row of incandescent lamps - and the competitor perceived the instructions directly (by eye) or by equipment (receiver). If a personal transceiver is used instead of the personal receiver mounted on the body of the athlete and a central transceiver instead of the central transmitter, a complex device can be created in the current state of the art which at the same time determines the state of the transponder The athlete's information and corrects the program prescribed in the training plan, thereby Athlete will always receive instructions for the optimal tempo change appropriate to the current situation. With the help of a

The type of instruction transmission may also be combined, which allows the athlete to be sure of receiving the instructions in every instantaneous body position, and in every attentional direction. The central transceiver may partially emit the instruction, "and the transceiver located on the athlete's body can simultaneously sense multiple stimuli (auditory, tactile, with the bones, and electromotive stimuli, etc.). On the other hand, the central transceiver system can be connected via lines or wirelessly to the control unit of the light signaling device arranged along the track. In this case, the athlete feels on the visual, acoustic and the path of the signal. The sense of touch is one and the same stimulus, and it exerts itself on all its movements without any particular distraction of attention.

The guide according to the invention is thus characterized essentially by the closed control chain. Accordingly, the invention is that the personal receiving device forms part of the personal transceiver and the modulating signal input of the transmitting device is directly or indirectly connected to the signal output 'at least one receptor attachable to the athlete's body, and the central Transmitter forms part of the central transceiver device, wherein the output of the receiving apparatus of this device is connected to the signal input of a signal processing device and the Moduliersignalingang the transmitting apparatus of the device to the signal output of the signal processing device. Such a signal processing device generally has an evaluation unit connected to the output of the receiving device, a program-setting unit connected to the basic signal input, and a difference-forming unit, at the two inputs of which an output of the respective program is output.

unit or the signal-evaluating unit, while the output of the difference-forming unit is directly or indirectly connected to the Moduliersignalingang the transmitter. The connection is instantaneous if the output signal of the difference-forming unit already directly represents the tempo to be transmitted to the athlete; it is indirect if, in the intermediate adaptation signal of the difference-forming unit, it must still be converted into a signal form directly perceptible by the athlete.

Preferably, a device is equipped with a display unit composed of a large number of elementary display devices (for example lamps) arranged along the path, the latter being connected via lines or wirelessly to the corresponding output of the central transceiver.

The personal receiver has expediently an acoustic stimuli and / or tactile stimuli and / or electromotive heaters generating signal generator.

The personal transceiver may include batteries, an accumulator, or a power supply unit powered by the distributed energy of the central transceiver.

Explanatory note: -

The invention will be explained in more detail with reference to an embodiment with reference to the drawings. Show it:

1 shows the activation mechanism which is to be realized

Pig. Fig. 2 is the block diagram of the embodiment chosen as an example.

At the one in Pig. 1 of the apparatus, the trainer sets the tracer 'the fundamental signal A, i. provided on the basis of the previous evaluation and planning. The time course of the value struggle. At the start time of the athlete's personal transceiver device, no information concerning the process F of forward movement reaches the receiving device of the central station, and therefore the basic signal A is applied to the difference-forming unit K at only one input, while at its other Input the fact signal T = O arrives, ie the originally planned tempo arrives at the competitor's personal receiver in the form of the A-T (A-O) control signal. The receptors arranged on the body of the competitor now deliver signals which arrive as lead signals V in the signal processing unit J, from there as a corresponding fact signal T to the second input of the differentiation unit K. ! Do the control signal A-T is no longer necessarily equal to Hull, it is usually different from zero and passes through the transmitting apparatus of the central station to all places where influencing stimuli are awakened, i. In the first place, the control signal reaches the personal receiver, which is attached to the body of the athlete, where it exerts on the various sense organs acting stimuli, possibly also to the control unit of the arranged along the route lamp row whose lamps in the expressing the correct movement If it does, it will glow in the appropriate order.

It is obvious that with this mechanism, the sound and light signals transmitted to the competitor of the speed necessary to travel the course can be programmed accordingly. By virtue of the signals supplied by the competition-mounted dual-wavelength transmitters operating on different wave bands, e.g. At any moment the actual speed can be compared with the planned during the

square mean of the actual speed gives information about the energy reserves and the instant adaptability of the athlete. There is a presupposed but not proven relationship between the dynamics of the change of the pulse under load and the port movement speed. By determining this relationship, the training load process, ie the dynamics of the load, may change significantly. There is opened up a possibility for the verbal regulation of the speed of movement, thus for the reinforcement or for changing the assumed tempo. Of course, the electroacoustic transducer of the personal receiver can not only pass tempo impulses, but also textual instructions if necessary, although the tempo impulses influence the heavily loaded competitors so that they basically do not disturb him, while textual instructions may possibly interfere with the ongoing process can. Therefore, these two forms of intervention, although carried out with one and the same technical means, are technically seen as two completely different procedures.

FIG. 2 shows an exemplary embodiment of the device according to the invention as a block diagram, specifically the receiver channel 200 of the receiver 20 of the central transceiver station, which has η channels (eg 10), a transmission channel 100 of the transmitter 10 having η channels the input 10a, the personal receiver 300 of the athlete's body mountable transceiver, and the personal transmitter 400. The output of the transmission channel 100 is labeled 100c.

Of all the channels of the device switched on, a multiplicity of instructions carrying signals from the transmitter 10 of the central transceiver system are transmitted to the antenna, are emitted from there and are transmitted to the antenna.

Tenneneingang samtlioher personal receiver 300, where the selection of the person's intended signal can be made with any known Selektierungsverfahren of the directional technology.

Similarly, each of the personal transmitters 400 transmits a signal containing the information about the athlete concerned, the antenna of the central receiver 200 receives all the signals broadcast by all the personal transmitters 400, and each receiving channel 200 also selects by known means the ' signal assigned to the respective channel. Accordingly, the various parts constituting the entire system are constructed.

The personal receiver 300 includes in series a selector 301, a decoder unit 302, an amplifier 303 and a buzzer 304. In the personal transmitter 400 are connected in series an oscillator 401, a modulator 402 and a power amplifier 404, and at the modulating signal inputs of the modulator are the outputs of the body of the athlete mounted Meßorgane tind receptors - directly or via a Signalvereinigungstufe -. on. For this reason, the measuring elements and receptors connected to the modulating signal input are collectively referred to as measuring unit 403. The concrete structure of the above-enumerated different units of the personal transceiver device is known by the 8Ji.

Each receive channel 200 of the central transceiver includes in series a selector 201, a decoder 202 and a signal processing unit 204e. One output of the selector 201 is connected to the input of the decoder 202, while another output of the selector is applied directly to the signal ver -

operating unit 204 connected iat. The output of the decoding unit 202 is connected to the input of a first registering unit 203, and an output of the signal processing unit 204 is connected to the input of a second registering unit 205. Of course, the two registration units 203 and 205 do not necessarily have to be implemented as structurally separate units; they may be the different fields of a single latch in a manner well known in modem data processing technology, but in this case they are system independent as two independent ones. to consider each other existing units. The second output of the signal processing unit 204 is simultaneously the output of the transmission channel 200.

The transmitter 10 of the central transceiver includes. ' per channel - a programmer 101 and a difference unit 102. The input 101a of the programmer is directly or indirectly connected to the unillustrated control of the channel, the output 101b is connected to one input 102a of the difference unit 102. At the second input 102b of the difference formation unit 102 is the output of the receiving channel 200. The transmitter 10 includes at least one Dodiereinheit 103 and at least one power amplifier 104. If only one coding unit 103 is present, so are the outputs 102c of the differentiation units 102 of the individual transmission channels and though via a multiplex organ. Of course, each transmission channel 100 may also have its own coding unit 103 and its own power amplifier 104. * The inputs and outputs of these two stages are 103a, 104a and 103b respectively; 104b. In Fig. 2, this is the sake of clarity, so shown, in general, it is. However, not appropriate. It is also possible to assign an encoding unit 103 to each transmission channel 100 and to encode the already encoded signals of all transmission channels.

channels 100 to the input of a common power amplifier 104. The operation is basically the same in all cases and can be well taken from Fig. 2.

The device operates as follows: The trainer feeds the tempodictive instructions corresponding to the training plan which he has worked out into the program generator 101 of the individual transmission channels 100 (an operator console, not shown, serves this purpose). These instructions either proceed unchanged (if, according to the mechanism mentioned in connection with Fig. 1, the signal reaching the second input 102b of the differencing unit 102 has the value Hull) or correspondingly corrected into the coding unit and amplified to the antenna. Of course, the coding unit not only effects the conversion of the instruction information into output signals but also the emission of identification bits which enable the addressed personal receiver 300 to select the instructions intended for it from the transmitted signal set. By decoding the selected signal, the instruction signals are produced in the personal receiver and transmitted to the athlete after appropriate amplification by means of the signal transmitter 304. The signal generator 304 may have different signaling means and in this way simultaneously transmit the instruction acoustically, visually and via the sense of touch to the athlete. At the same time, the instantaneous signals of the different measuring organs and receptors attached to the body of the athlete modulate the carrier signal of the oscillator 401. This is then amplified and radiated. The selector 201 of the corresponding receiving channel 200 is sensitive to the wearer of this personal transmitter 400 and forwards the selected "signal to the decoding unit 202 and to the signal processing unit 204. The decoding unit 202

If the medical-biological data supplied by the measuring unit 403 is recovered from the modulated signal, it is written into the first registration unit 203 and forwarded to the signal processing unit 204. The signal processing unit 204 also receives the received signal directly from the selector 201 and derives therefrom the data characterizing the movement of the athlete, ie the data relating to the actual tempo. The data relating to the tempo is written by the signal processing unit 204 into the second registration unit 205. The evaluating circuits of the signal processing unit 204 are designed by those skilled in the art using the usual methodology in data processing technology such that the unit provides the medical biological data and relates the tempo data to the setpoints assumed by the trainer. If, at the actual tempo, the athlete's load exceeds the desired level that is detrimental from a health point of view or condition for the prepared competition, then the resulting information with a weakening sense enters the difference unit 102 of the transmission channel 100. If the condition of the competitor indicates reserves which allow an increase in the tempo, the resulting information with an increasing sense enters the difference-forming unit 102 of the transmission channel 100. Of course, this is just the basic case of the signal processing mechanism. The load capacity of the carrier signal may be changed, ie the transmission channel 100 may be suitable for receiving different interference signals and their incorporation into the instruction signal. Also, the expansion of the signal processing unit 204 may be different, for example, a single merging signal may modify the tempo instruction according to a resulting magnitude obtained from a plurality of independent variables.

The personal broadcasting equipment may be attached to the competitor's head or to his cap, further by means of a belt on the arm, on the back or on the chest, etc., so that. the device does not hinder the competitor in the movements under the conditions of the respective sport, the receptors are in good operative connection with the signaling organs.
