Translation of description of equivalent WO 2015117735 A2

Zeitmessaniage

The invention relates to a timing system for measuring the duration of a rotor according to the preamble of claim 1. Such a timing system is known by EP 1 646 432 81. Here, in a running competition to the presence of a predetermined points

Running path generates a presence signal of the rotor, for example, the start signal and the target signal. For this purpose, at each point the presence of a light source is placed, which crosses the traveling path perpendicular and impinges on a reflector. The light beam to the light source, said back exactly throws a light beam receiver Upon interruption of the light beam generated by the

Beam receiver a presence signal. This is established as a measurement pulse over a situated in the area of ​​the signal transmitter radio to the head of the gangplank

transmitted timepieces and serves as a switching signal by which the timer is set on or off in transition.

This timing system has the drawback that for detecting the presence of a runner (2) at any of the running track intersecting line presence, a light barrier, consisting of a light beam source with constant or constant pulsating beam of light, a

must be light beam receiver, and a reflector arranged and connected to the centrally disposed timer for transmitting the switching signal. This is to

Establishment of a running track with such a timing system requires a considerable expenditure of time and it is to avoid Fehlem a good training of the staff employed with the installation and operation of Zeitmeßanlage personnel required.

Object of the invention is to provide a timing system that will be built in a short time kan and thereby requires no electrical installation or adjustment, the proper execution of a special training and monitoring requires that performed particularly well in schools of the teaching staff with little effort or monitored can be.

The solution includes a timing system for timing the duration of a runner on a running track between two attendance lines crossing the running track, with detection means for detecting the presence of the rotor on each of the

Presence of lines, said detection means consist:

from a light beam source, whose constant or constant pulsating light beam is aligned along the presence of line and the path of travel crosses on a measuring axis which is perpendicular to the presence of line, a reflector which is arranged in the light beam and the light beam as a measuring beam along the

Attendance line reflects, a Meßstrahlempfänger (beam receiver), which is arranged in the direction of the reflected measurement beam on the presence and line generated by interrupting the Meßstrahlempfangs a presence signal of the rotor which, the

Timepieces in the timing system is transmitted as a switching signal, said

Lichtstrahlquelie (6) and the light beam receiver (7) structurally to a pairing signal (5) are combined. It is according to the invention before the head of the running track a unit is installed, which contains the timing system and the running track has been created such that all for detecting the presence of the rotor provided on the

Presence lines required signal pairings (each consisting of

Light beam source and light beam receiver) integrated into the constructional unit and are disposed on at least one of the path facing outer sides of the assembly, in particular in the embodiment of Claim 1.

This timing system all electrically operated components are centrally and openable

Preferably (claim 2) integrated in one structural unit.

, For electrical equipment the running track only the pairing of the light beam source and the light beam receiver must be so placed in front of the top of the running track centrally aligned with the light beam parallel to the running track and electrically switched. For battery operation, a wiring is not needed. In addition, is at all present lines where the presence of the rotor detected and should be made the subject of a time measurement, only the installation of reflectors, ie, each of a deflecting mirror and a

End mirror required a purely mechanical activity that does not require precise knowledge of the time measurement technology. The necessary for timing adjustments can be made on an input device of the headend through switch, a keyboard or the like. The headend may also include a computer and storage capacity ,.

The unit also offers the advantage that the formation and arrangement of the light beam sources and light beam receiver set and therefore no special

Prior knowledge can be carried out. By appropriate equipment this unit, referred to in this application as a head end, several different running routes and games can be specified. The timing system is particularly suitable for schools, where sometimes playful applications sporting applications are in demand times, can be ensured by varying the running routes but always for variety and interest. In particular, in the embodiment according to claim 1 can be realized these benefits. Developments of the invention featuring several basic arrangements and embodiments of the head-end station and it would set up running distances. It follows that by means of a suitably equipped headend running tracks with different length, different courses and different timing, the entire running track between the start and finish (claim 4, Fig.1 & 3); can be staked; from sections existing runs (Fig.2,4,5,6 claims 3,5,7).

The running tracks can extend in a direction (Figure 1,2,3;. Claim 3.4) or U-shaped folded (FIG 4,5,6;. Claim 4,5,7). The running tracks can be straightened (Fig.1- 4) or zigzag or extend serpentine wound. (Fig.5,6).

In addition to lying on the front side of the headend signal generators also lateral switch with Lichtstrahquelle and light beam receiver can be attached to one or both of the running track facing sides of the head station to get more options for varying the running tracks. In this case the reflectors are simple mirrors which are situated on the other side of the running track and pointed directly at the respective signal transmitter (2 to 6;. Anspruch6 and 7).

The settings required at the headend can be programmed so that only the required adjustment program must be called by the input device / keyboard. It also test runs can be programmed so that when calling a certain running program, the establishment of the necessary presence of lines with the right

Statement of reflector systems can be automatically monitored and verified at the headend, each with a tilted mirror and a cooperating end mirror.

Thus, the invention focuses the establishment of a running track at the head-end, ie the formation and adjustment without the need for the installation and wiring or other electrical connection to other electrical equipment is required.

In the following embodiments of the invention will be described with reference to the drawing. Show it:

Figures 1-6: different equipment of timing systems with examples of

Running tracks, which can be set up so ..

In the following functionally identical parts are provided with the same reference numerals. The following description applies equally to all embodiments shown, unless it is pointed at an individual embodiments to special features.

The timing system is the basic equipment of a radiation source as 6.2

LSG light beam source, a light beam receiver 5, and a data processing device (computer) including timer and input means such as keyboard, and switches. As

Light beam source is a laser beam source in particular those in which the light beam is sufficiently bundled energetic and strong, so that measurement errors can be avoided by light scattering.

The headend is a box or a rectangular housing 9. It is in the starting line 10 and set up the standby line 11th The rotor 2 is waiting outside this range before the standby line 11th

The head station 9 comprises one or more structural units, referred to as a signal generator 5 and consisting of light-ray source 6 and light beam receiver 7, both of which are directed in the running direction. Such units are commercially available. It is light beam sources, the continuous or pulsating light beams to emit and receive especially laser beams can. By receiving or by interruption of the reception (negative pulse) is proposed for an electrical signal to the computer

Further processing can be abandoned and may be given the timepiece as a start signal or stop signal with appropriate programming of the computer.

The signal generator 5 are mounted in the head station preferably that light beam source 6 and light beam receiver 7 lie horizontally side by side and the transmitted and the received light beam in a horizontal plane, the light beam plane lying.

In the light beam level them is opposite the reflector system, in this application generally referred to as "reflector 10" respectively. The reflector consists of a reflecting mirror 0.1, something besides the running track located, and the end mirror 10.2, located on the other side of the running track.

The reflector 10 is satisfied by the establishment of these two levels on an attendance line the task of directing the to the running track emitted toward or parallel light beam to the presence line and the emitted light beam to return the reflected return beam to the light beam receiver 7 parallel again.

For this purpose, the two mirrors of the reflector system are on the line in the presence

placed horizontal light beam plane and aligned in vertical planes, prism-like to each other. The light beam source 6 is therefore directed to the deflection mirror 10.1. The vertical plane of the deflecting mirror 10.1 forms with the light beam coming into the light beam, an angle of 45 °. Thus, the reflected light beam from it crosses the running distance substantially at an angle of 90 °, and strikes the end mirror 10.2. The vertical plane of the end mirror 10.2 is on the other side of the running track and forms with the deflected in the presence of line light beam in the light beam, an angle of 90 °. This means that the light incident on the presence of line light ray is reflected back in the same direction to the deflection mirror 0.1 and from the latter to the light beam receiver. 7 Thus, the light beam crosses between the deflecting mirror 10.1 and the end mirror 10.2 two Times the running track. If the light beam between the deflection mirror 10.1 and the end mirror 10.2 or between the signal generator 5 and the reflector system interrupted by the passing on of the running distance runner, this negative pulse is -As establishing a time point of the barrel used geschildert-.

On each line presence 3 So each one reflector 10 consisting of deflecting mirror 10.1 and 10.2 end mirror is arranged, provided that the presence of line -in Laufrichtung- is before the headend. can- If the presence of line equal to the headend, as especially in the start and / or finish line to be the case as the signal transmitter 5 with light beam source 6 and light beam receiver 7 is attached to the side and perpendicular to the running track. In this trap, the reflector consists of a single end mirror, which is positioned on the other side of the running track and throws back the light beam directly to the associated light beam receiver.

As attendance line each line is referred to in this application, on the rotor to be detected when running over the running track for the purpose of recording time. A significant presence of line is therefore the starting line 3.1, another the finish line 3.2. In addition, sections 4.1, 4.2 or the reverse path 4.3 of the total running distance may be labeled to detect partial and interim periods by the presence of lines but.

If the runner crosses a line presence which to intersecting light beam is interrupted briefly. This means that the light beam receiver 7 receives no signal. This negative pulse is detected by a built-in head-9 computer, microprocessor 14 and, as a start signal or stop signal or intermediate signal to the timer 8, which is also part of the computer capacity and is integrated visible in the head station from the outside. The computer 14 also includes input devices, in particular a keyboard 16. In addition, the computer-capacity also includes an internal memory. Therefore, inputs can be made to program different running routes and set to the corresponding running tracks and the importance of the individual signals

pretend.

it is also very advantageous if the headend includes a printer, which will be notified by the rotor, the length and the course of the running track and the duration and possibly the intermediate times.

The timing system of Figure 1 shows that in such a headend 9 two switches are 5 integrated on the front side of the housing, each with Lichtstrahquelle 6 &

Beam receiver 7. Both are oriented towards the running track 4 and located slightly beside the running track. The right signal transmitter 5.2-operates with a reflector 10, together with deflection and end mirrors 10.1 10.2 that the presence on the first line, Starting Line 3.1, are arranged. The left signal transmitter 5.1 cooperates with a reflector 10 with a reflecting mirror 10.1 and end mirrors 10.2, which on a second

Attendance line, the finish line 3.2 are arranged. In both cases, the deflected light beams cross the running track 4 at an angle of 90 °.

To set up this running track headend 9 erected shortly before the planned start line 3.1 and aligned with the Signalgebem to the planned start line 3.1 and finish line 3.2. Then called the keyboard 16 a program right the

Signaler 5.2 assigns the function to set the timer 8 in gear and the left signal transmitter 5.1 assigns the function to stop the timer.

The rotor 2 takes before its run at the standby line 11 formation and dissolves by its presence on the starting line 3.1 the starting signal for the timer 8 and by his presence at the finish line 3.2 the stop signal.

The determined time can be made, for example, on a display of the timer 8 visible and / or printed to a printer.

The timing system of Figure 2 has a terminal 9, which is also in two

Direction directional signal transmitter 5.1 and 5.2 has, but in addition also a lateral signal transmitter 5.3. Opposite the side signal encoder 5.3 is a reflector 10, in this case, a simple mirror, placed on which the light beam receiver 7 of the lateral

Signal generator is 5.3 aligned. This right-side signal transmitter 5.3 detects the presence of the runner on the starting line 3.1, which is at the same height as the head end 9 ..

Situated in front of the head left signal transmitter 5.1 detects the presence of the runner at the finish line 3.2. The second right-hand front of the head signal generator 5.2 is a

targeted intermediate Attendance line 3.3 through which the entire running track is 4 divided into two sections 4.1 and 4.2.

To set up such a running track, the headend is 9 something placed beside the running track and so that the side signal encoder 5.3 is on the starting line 3.1 and the running track 4 of the rotor 2 crosses with its light beams at a perpendicular angle. Incidentally, requires the establishment of the running track a few simple steps by the

desired presence lines 3.1,3.2 and 3.3, respectively, a reflector or a

Reflector mating is 10 set by deflecting mirror 10.1 and 10.2 rear mirror. At the headend, a switching device may be provided through which the light beam source 6 taken up briefly and is determined based on a control light of the associated light beam receiver 7 if the reflectors are placed properly. The lateral right reflector 10 can be checked in the same way. Then called at the head 9 by means of the keyboard 16, a pre-input program, through which the negative pulses of the light beam receiver 5.3 of the side signal encoder 5.3 for starting the timer 8, the negative pulses of the right signal transmitter 5.3 to decrease an interval and the negative pulses of left signal generator from 5.1 serve to decrease the total time.

Here waits the rotor 2 at the standby line 11th

The headend contains 9 in this embodiment in addition to the signal transmitters 5 and the timepiece 8 also a willingness traffic light 13 for discharging a ready signal for the waiting runners. Also in this willingness traffic light 13 is connected to the timer 8 to pass the call time signal.

The embodiment of Figure 3 shows a very simple implementation. Only at the starting line 3.1 is a side signal transmitter 5.3 and above the top of the head station 9, a signal generator 5, each provided with light beam source 6 and optical signal receiver. 7 The details, in particular the function of the individual elements and the establishment and formation of the head station have already been described.

Figure 4 shows a timing system which is suitable for detecting the elapsed time and split times of a U-shaped folded running track.

The peculiarities consist in. There are two side signal transmitter 5.3 right and 5.4 left available with the corresponding reflectors 10. The headend 9 is set up so that these signal generators are 5.3 and 5.4 with their reflectors 10 at the start and finish line, the light beams are directed opposite .. the light beam receiver 7 of the right-hand signal generator 5.3 detects the presence of the rotor 2 on the start line 3.1, so when you start the light beam receiver 7 of the left-side signal generator detects the

Presence of the runner at the finish line 3.2.

The course consists of a Way 4.1, a return path 4.2 and the reversal length 4.3.

A traffic light with the direction of traffic lights 12, shows the waiting runner by a

Right signal or left signal on which side of the race begins and that the launch is imminent, and furthermore by the standby signal of readiness lights 13 that he has to start running. This also allows the reaction time of the rotor, ie the time interval between the standby signal and the presence on the start line are determined 3.1. Part of the running track of Figure 5 a terminal is used 9 in the equipment according to FIG. 4 However, the left side signal transmitter 5.4 is not used, so there is no reflector is installed. It will set up a folded transfer line, as shown in principle with reference to FIG. 4 However, the running track is carried out so that the start and finish are here on the same side of the housing 9 and are detected by the right signal transmitter 5.3 and the associated reflector. The course consists of the forward path 4.1 between the starting line 3.1 and the first reversal line 3.4, from the reversing 4.3. between the first and the second

Reverse line 3.4 and 4.2 the way back. This is done serpentine. The runner must run around the pylons 17, which directed on both sides parallel to the running track

Beams of the signal generators are installed 5.2 and 5.3. Then must return the runners to the finish line 3.2 on the right side of the housing. 9 It is seen that on the way back 4.2 negative pulses are received by the light beam receiver 7 of the signal transmitters 5.2 and 5.3, when the rotor, the light beams of the signal transmitter 5.2 or 5.3 crosses. This results in the ability to capture more part time to the pre-programmed presence lines 3.5 of the individual turning points.

It will be appreciated that instead of the return path and the paths can extend in serpentine fashion. In Figure 6 is shown that return trips run serpentine. The runner must circumnavigate on the run 4 pylons 17 so that it passes on the way (in Figure 6) to the right, on the way back to the left from the head 9 and -beginnend and ending at the start / finish line 3.1, 3.2- both on the way there and on the way back a

wavy path travels around the pylons 17 and conversely between the reversal lines 3.4.

In this course of the running track and the left side signal transmitter 5.4 is used and placed there auc the reflector 10, because in this case the starting line 3.2 is on the left side of the housing 9, so the rotor starts The goal is to the right of the head station. The rotor is there captured by the right-side signal transmitter when it reaches the finish line 3.2.

It is clear from these examples of different tracks, the invention and its meaning, namely, that a variety of different tracks can be defined solely by the equipment, programming, good positioning and adjustment of the head-end without further

electrical installations, apart from the purely mechanical installation of reflectors. numeral
