DE102009015331A1 - Transmitter-receiver system e.g. heart rate monitor, for use during crawl stroke in swimming pool, has receiver designed such that receiver registers input into transmission range of transmitter - Google Patents

Abstract

The system has a receiver (2) that is designed such that the receiver registers an input into a transmission range of a transmitter (1) in a digital or analog manner. The receiver is active and passive, and registered data is computationally or mathematically processed and evaluated. A transmitter is adjusted in a specific range, where frequency of the system is adjustable. The receiver ignores repeated perception of the input into the transmission range within a certain time interval.

Description

Field of the invention

The The invention relates to a transceiver system, in particular a device for detecting the repetition of movements, which over has a transmitting and receiving system.

State of the art

The Exercising various activities takes place often in such a way that a certain movement (for example, the laying back a track in the sport, passing a checkpoint) several times is performed. For the evaluation of the rendered Performance is in addition to the total time required above all the number of passes at one or more points along the route - hence how often the defined Route (passing a checkpoint in the work process, laps on the sports field, tracks in the swimming pool, etc.) became important. In the course of the activity occurs the "round counting" at the performer However, experience shows often by the focus on the service to be provided, the control the own exercise or simple drifting away the thoughts in the background. An error-free detection of the Cycle number or the exact achievement of a target is usually so prevented. As a result, the affected person is counted and the service provided is ultimately not beyond doubt to determine.

At the moment, individual and collective data collection systems are available, especially in the field of sport. Individual systems have the task of determining the services provided by individual persons. The required information is either with the aid of positioning systems, for example by means of a "GPS speed and distance monitor", as in DE 69920438 T2 described or autonomous, for example, in a "foot pod" as in the DE 69921040 T2 described by analysis of physical data, eg. B. acceleration, duration of motion won. That from the DE 69921040 T2 known system can be considered as a development of pedometer, which originally by means of mechanical, controlled by inertia flip-flops, such as. B. in the DE 29614528 or specifically for swimming in the area DE 29903149 respectively. DE 20212166 discloses the repetition rate of certain movements of the user. To record the repetition rate, as in the DE 3447171 C2 described, also electronic sensors are used. The aforementioned devices for detecting movements would have to be carried by the person concerned.

Next The systems for the individual performance recording are systems for the Collective service recording (so-called group-monitoring systems) known become. Such systems are stationary and received Performance data from multiple people with channels. For this count u. a. RFID-based chip systems, which For example, in mass sporting events (eg, endurance, marathon, Triathlon runs) find use. Also radio receiver to control z. B. count heart rate data of several athletes in training mode For this.

equipment for individual performance tracking are often due to their technical complexity correspondingly expensive and complicated to use. Their function is often dependent from a power supply to be carried (eg Foot Pod, GPS-S & DM, heart rate transmitter) and sometimes also the availability of more efficient Infrastructure (eg GPS). Especially with the simple devices increases the risk of failure with the service provided. This is because the overall result is determined indirectly: Recorded performance data is based on previously entered Parameter extrapolated, so that even with precise detection of Performance data the accuracy of the overall results of the strong Correctness of the basic assumptions (eg assumed average Step length) depends.

RFID systems aim both in their active, d. H. the chip sends independently Data, as well as in their passive form, d. H. the chip is added Migration of an induction field based on its specific Reaction to this recognized on the controlled capture of Performance data of a majority of persons. The data are in the Moment of capture not the affected but only one at the receiver available person. Furthermore, these require Systems regularly have a significant technical, organizational and thus financial expenses.

Description of the invention

task The invention is to provide a simple device to provide that overcomes the disadvantages of the prior art and with their help, the repetition number of one or more movements, d. H. the number of cycles determined reliably and without error can be. The control should be exercised by the movement Person can be performed at any time, without to demand their constant attention and thus theirs Focus on the exercise of the actual activity limit.

This object is achieved by a transceiver system having a transmitter and a receiver ger, wherein the receiver is designed such that the receiver registers each entry into a transmission range of the transmitter digitally, ie binary or analog, ie differentiated by signal strength, ie the registration of the cycle number is transmitted to the usually carried by the person receiving , The receiver is designed such that it detects the relative movements of transmitter and receiver to each other via the detection of the varying depending on the distance to the transmitting part, received signal in digital (= digital) or analog (= differentiated by signal strength) form and to process such that the number of motion repeats can be detected.

In the device according to the invention or the transmitter-receiver system, two complementary devices are used:
On the one hand, a signal generator is placed at a certain point along the route to be traveled. It transmits a signal with a short range (eg - but not necessarily or exclusively - a Bluetooth signal). Ideally, the range of the signal is variably adjustable to allow adaptation to the local conditions and the peculiarities of the activity performed. On the other hand, the person carries with him a receiver, which registers the signal as soon as it enters the transmission range of the signal generator.

Around to prevent the signal from passing slowly through the Transmission range or with repeated entry and exit with only one Cycle of the cycle is registered multiple times, it is advantageous on the receiver to make the repeating distance adjustable. If such a repeating distance is set and becomes the signal within this repetition interval or this period of time several times captured, all perceptions after the first are ignored and thus do not lead to an increase in the count. Conveniently, both devices, d. H. Receiver and transmitter, be multi-frequency constructed, by means of individual settings interference by other persons with the same equipment ("interference", "crosstalk") to prevent. Also, this would be a common use possible from signalers. In a community use several people could use the same station. At a Line segment measurement uses a person several stations or more People use the same channels.

Further possible functions or optional functions of the invention Systems, z. B. an acoustic / optical control, which can be designed permanently or on request, the signal reception or the current / remaining cycle number to achieve a previously programmed destination. Such a control can be one flowing transition into a count of the predetermined target exceeding cycles or the renewed Redemption of the target.

A automatic frequency detection and search function of the device can make sure of the alternatives available a signal is selected which does not match one already The frequency used on site is identical.

By Attaching appropriate devices (eg opening for Kensington-Lock) is an effective protection against theft possible.

One (Splash /) water protection, for example, the recipient and / or Sender would also use the outdoor area or in wetlands (eg swimming pool).

One special field of application of the invention Transmitter-receiver system is the reliable one Detection of the repetition of swimming movements, for example the capture of swimming laps or the capture of floated ones Tracks in a swimming pool. Especially when capturing the Repetition of swimming movements, it is advantageous if through Specification of a repeat distance or a time span the multiple Detecting the entry into the transmission range in the same cycle avoided becomes.

The Invention will be described below by way of example with reference to the drawings, without limitation, will be described.

It demonstrate:

1 basic operation of the system according to the invention;

2a - 2d Example of a multiple entry of a receiver in the transmission range of a transmitter at Crawl swimming;

3 Example of multiple senders and multiple receivers;

4 sharing a signal generator by multiple receivers.

In 1 is the basic operation of a transmitter-receiver system according to the invention for detecting the repetition of movements, in particular swimming movements, shown.

This in 1 shown system has a transmitter 1 on. The transmitter 1 emits a short-range radio signal, for example a radio signal in a royalty-free ISM band between 2.402 GHZ and 2.480 GHZ, as it is also emitted by so-called Bluetooth devices.

Concerning the establishment of radio links in the short-range range with so-called Bluetooth signals is added to the entry "Bluetooth" in the encyclopedia Wikipedia referenced.

Instead of a short-range radio transmitter, for example, with a Bluetooth protocol works, the transmitter could also be one Be infrared transmitter.

The transmission range of the short-range transmitter 1 is with 3 referred to in the present drawing.

The recipient 2 for the short-range signal is from a person 9 worn along the path 5 emotional. Kick the person 9 along the train 5 , which moves in the direction of the arrow, at the point 7 in the radio range of the transmitter 1 a, then the count becomes the receiver 2 that of the moving person 9 is carried, increased by one. In this way, it is possible to grasp exactly how many times the moving person is cycling 5 has gone through. Example of a movement, as in 1 shown is the use as a lap counter during the lap run on a sports field. Alternatively, the number of laps in a pool or the number of laps in a swimming pool could be counted. If you want to count the number of floated lanes, then the count number of the receiver 2 in each case back and forth along the track increased by one. So you can get the exact train number to the receiver 2 remove. The person 9 in the present case carries the receiver on the arm.

It is very important that the count only when the recipient 2 is increased in the count range by one. In a simple movement such as a lap run, care must be taken not to increase the number of counts in the same round by repeatedly entering the receiver. For more complex movements, especially when swimming, preferably at crawl swimming, but this would be the case and must be suppressed accordingly. The suppression of a false count on multiple entry into the counting range or radio range of the transmitter can be done for example by means of a repeating pitch adjustment. The mode of action of such a repeating distance adjustment using the example of a crawl swimming movement is shown in FIGS 2a - 2d shown.

2a shows, with reference number 10 characterized, the movement of the right arm when Kraulschwimmen.

In 2 B is the movement of the right arm over the ground with the crawl swimming with reference numeral 20 characterized.

2c shows the repeated movement of the right arm (a total of five arm movements) over the ground at the crawl swimming and is with reference numeral 30 designated.

In 2d in turn is represented as by the in 2c Repeated movement of the right arm, to which the receiver is attached, for example, in a watertight execution, several times in the radio range 3 a transmitter 1 entry. The transmission range is with the reference number 3 , as in 1 , marked. Further characterized is the first entry point A of the receiver mounted on the right arm of the crawl float, the second entry into the transmission area at point B and the third entry into the transmission area at point C of a crawl swimming movement. To prevent the entry of the recipient at the in 2a - 2d is counted three times and thus leads to a false result, it is provided to set a repetition interval or a time period for the multiple detection of entering into the transmission range of the transmitter at the receiver. For example, knowing that a lane is swimming in one minute, but the movement of the crawl movement is completed in one second, a repeat distance can be set to 30 seconds. This will ensure that despite three times entering the crawl swimming, as in the 2a - 2d shown, the receiver in the radio range of the transmitter 1 the count is increased by only one, which coincides with the actual number of cycles.

If several users want to use the transmitter-receiver system according to the invention, crosstalk and interference can occur. To prevent this, it can be provided that the transmitters are designed to be multi-frequency, ie that transmit radio signals at different frequencies depending on the setting by the user. In 3 this is the example of lap counts of three users on three different tracks 5.1 . 5.2 . 5.3 shown. Each user on different tracks 5.1 . 5.2 and 5.3 is a separate station 1.1 . 1.2 . 1.3 assigned. Each of these transmitters transmits a radio signal in a range at different frequencies. The radio signal with a first frequency of the transmitter 1.1 sends in the area 3.1 , The radio signal of the second transmitter 1.2 with second frequency sends in the area 3.2 , The third radio signal of the third transmitter 1.3 sends in the area 3.3 with third frequency.

As the different users enter the different areas, the rounds become individual due to the different frequencies of the stations 1.1 . 1.2 . 1.3 for every user on every lane 5.1 . 5.2 , 5.3 detected.

In 4 is the shared use by several persons of the same sender or a segment measurement, in which several people use the same channels. The paths of the persons are with 50.1 . 50.2 . 50.3 marked, the transmitter with 100.1 . 100.2 and the associated transmission ranges with 103.1 . 103.2 ,

By the invention becomes a reliable determination of cycle numbers in the context of any spatial movement (eg paid / professional, athletic or therapeutic activity) possible. Neither the actual activity nor the attention the practitioner is affected, which, under otherwise equal conditions, the accuracy of the performance as well as the quality of the activity should be increased.

The Assignment of the active role to the usually stationary Sender and the passive role to the usually mobile receiver allows a minimization of the practitioner to be moved Mass, because the energy requirement arises mainly at the transmitter. Nevertheless the active person always has up-to-date information to disposal.
