Description

GERMAN

The invention relates to a method for determining the resultant from one behind the other Crossing points of four cores with different labeling containing line structures, in particular telecommunication cable quads. To the mutual influence of telecommunication lines and the It is known to reduce or eliminate the influence of external interferers on these lines Swap lines according to certain intersection schemes. As is well known, the elimination of the mutual influence in the transmission technology on symmetrically operated lines of a of the main main problems. Whenever lines are operated in parallel over a longer distance, energy passes from one line to the other and there more or less disrupts the transmission. this applies to both cable and overhead lines. In the course of the development to ever higher frequencies the crosstalk that occurs with overhead lines and stranded cables has also increased, so that you can partly through constructive measures, z. B. by a uniform structure of the lines as possible and cables, partly through a subsequent compensation that is as perfect as possible for the cross-talk properties seeks to improve these lines. The ones to eliminate crosstalk in telecommunication cables Required crossings made simply because of the large number of in the crossing sleeves existing number of cable pairs and the associated constant risk of interchanging wires extreme care of the assembly personnel and largely require specialists for the examination and determination of the intersection schemes.

A number of methods are known per se for testing the conduit passage. One known method is used to determine the individual lines running in a bundle. In this method, the individual ends are grounded at the starting point of the line bundle in any basic division via resistors of the same size connected between them or connected to an auxiliary line, while At the point where the determination is to be made, a current indicator, which is also earthed or connected to the auxiliary line, and the current source are connected to the individual lines one after the other. Another method is used to search out faulty lines from a bundle of several lines running towards one another. The defective line is electrically operated from one of the terminals, e.g. B. with a spark gap, excited. The disturbed point can be determined with the aid of a wave-sensitive display element, which is guided along the bundle of cables. It is also a device for the process

Checking multi-core cables for correct core sequence of the individual conductors known. Here are at the one end is connected between the individual wires and earth with equal resistances, while at the other end End of relay matched to the resistors connected to indicate the correct cable cores are. The known methods are therefore intended for the passage of a line or the beginning and seek out the end of a conductor located in a cable.

The general object of the invention is to develop a method that, in addition to determining the resultant of any number of consecutive intersection positions in the Four also the control of the crossing positions practically carried out in the cable and the determination of mixed-ups, tearing of four and broken veins in the shortest possible time and on The simplest way, reliably and error-free, also made possible by assistants.

To carry out the method mentioned at the outset, according to the invention, at one end of the line a DC voltage source to each wire pair and to the other end of the line in the same

Assignment of the wire identification to each wire - the series resistors for setting the currents emitted by the pair of a current intensity and direction-dependent DC voltage sources, z. B. connected in the display device and the two currents ratio 1: n, are used. This set so that it can be differentiated as desired and the deflection ratio can of course also be achieved without series resistances of the display devices as a criterion for the 5 by a battery using a multi-result crossing position. The voltage of the other battery can be as high as the voltage of the other battery, the current intensity and direction-dependent display. In general, the setting of the current ratios from devices arranged next to one another with an instrument is not very critical, as long as only the given zero mark exist or currents can still be clearly distinguished permit. The display devices in the system bilio auxiliary device, which consists of pointer and contact track, are used to control the fours present in the cable when the current passes through them. the beginning of the quadruplets to be tested are used in the correct color of the intersection positions for the minimal display. It is closed, especially when it comes to operation. In the case of faultless crossings of measuring devices by auxiliary staff, the display of the display devices must often average the resultant of the crossing points when reading the pointer positions on instruments, which correspond to the direct reading of a value found. In the event that there is no flap on which the relevant intersection position as an instrument gives a display, the one written in the number and triggered by the step device and the pressure switch located in the auxiliary device are avoided. The 20 keys are pressed, which results in a quick and reliable result of the cross-checking of non-permissible crossings, z. B. Use positions could also be taken from tables that had been torn apart beforehand or that had been mixed up with four cores; this determination interruption is carried out. The check would be cumbersome and time consuming. In order to be able to determine the fours of the four in the cable on the core bottom sum of the intersection points for intrusions, interchanges of four or the like, it is known to be able to determine a number of times, quickly and reliably.

In a further embodiment of the invention, the invention is to be created on the basis of some preparatory auxiliary devices that explain at least representations. For crossings in four three, preferably four fixed in this device, a total of eight switching or crossing positions placed four with the interposition of one 30 are permitted, the eight-pole in Fig. 1 of the drawing, left column I, eight-pole, the usual eight crossing positions are arranged one below the other are. At the beginning the production selector switch is connected in series, the following should be noted: While the intersection point during the ends of the series connection with currents 1 to 4 consist of intersections in the respective trunk sources and display devices according to the procedure, at the intersection positions 5 to 8 according to the Invention are connected. This Wahlschal- 35 a crossing out of the trunk, so that, for. B. ter can be equipped with two switchable areas according to position 5, the trunk 1 behind the intersection, in such a way that the usual point continues as trunk 2 in the first area, and vice versa. Crossing positions 1 to 4, in the second area which are carried out in place of the usual colored representation of crossing positions 5 to 8. Four with the wires white, red, green and blue. The second area can also be blocked mechanically, the wires a, b, c, d in FIG. 1 by means of dots. This measure avoids distinction between crosses and dashes. According to the voltage error, -da in some cable systems, z. B. in Fig. 1, left, arranged crossing position of the Federal Railroad, only the crossing positions 1 to 4 fours are in the next following column II which are permitted and thus with separation of the two trunks I and II the four with batteries and instruments, the crossing positions 5 to 8 containing elements 4-5 connected ΛI and StII . So is z. B. when setting the switch in the auxiliary trunk I with its cores a, b to the battery BI device this determination is right from the start, which is carried via the adjustable series resistor R 1 the voltage. In order to determine the flow that causes a corresponding resultant of the individual intersection positions and corresponding deflection in the instrument StI. The battery B II is connected to the trunk II of the necessary setting of the multiple fours c, d via the pre-pole switch in the device, which causes an unnecessary deflection resistance R 2 to be avoided Setting of R2 provides a deflection in a push-button which only corresponds to the «-fold current of StI, eg the setting of the crossing positions in the fixed current 2 i, after the completed .SiII. The four-way selector switches with a zero mark moved see the display, which connects the positive and negative current direction to devices with their circuits. For the pointing instruments StI and ΛII, however, with their case that one wants to observe the resulting intersection position next to one another in the next column III after each switch setting, one can see that this push button is not used . Pointer position for the respective intersection position of the addition to the determination of the resultant behind 60 fours is characteristic. In the individual intersections lying one above the other, the procedure is used, according to the invention, among other things, the control of the connection of the wires with the batteries and instruim cables, which run over several sleeves, has been retained, only the cross fours . For this purpose, in a further exposed position of the quad, the device for passage I is changed in accordance with the left configuration of the invention, so that the deflections of the procedure are created in such a way that the instruments StI and ΛII are also different at each end of the line with a pair of wires and a direct voltage source that is characteristic for the respective crossing position, along with its statistical value.

B. given on stepping mechanisms, a number of the corresponding Trigger a flag containing the intersection position and thus a direct numerical one Enable display of the respective intersection position. To realize this thought is FIG. 2 shows a device which, instead of the directly readable instrument scale, has a pointer 1 contains, which when the instrument deflects a

To answer this question, the intersection scheme has been shown in drawings or in thought presented and followed the single foursome through each sleeve of the route to the desired one To determine overall or end intersection position. We have this previously usual way in Fig. 4 and it can be seen from this that the foursome viewed over the entire route is the total cross

A zero position is equipped with the contacts 2, 3, 4, 5, another embodiment of the inventive concept based on the positive and negative taps of one is that an auxiliary device for the eccentrically earthed battery 6 is located. Now this exercise of the method according to the invention created instrument z.

or electrical lock ensures that when you return

such instruments provided with contact tracks, on the other hand, deviate from this in 30 subsections

the trunk I and trunk II are switched on, the display of the respective crossing position of the Also represent fours with the help of characteristic pulses, such as those in Fig. 1 in the right Columns IV and V are indicated.

After this preparatory illustration, a practical case is now shown in Fig. 3 in which a Telecommunication cable 1 is provided with three junction sleeves I, II and III. The different one after the other

have switch positions, a switch must also be available for each section. At the end and beginning of the quad in the auxiliary device are again, as was the case in the preparatory illustration carried out at the beginning, two batteries 51.511 with the currents ι and 2j, which can be regulated via series resistors Rl, R2, and the two display instruments StI and StII.

Fig. 6 shows the switches I, II, III of the

This result is used here for certain reasons, e.g. B. to reduce is in accordance with the by the tedious change of the crosstalk, transferred to the intersection point and very often error-prone tracking of the individual lung 2, runs in this example in the

while position 1 should be present again in the following route. The number of intersections and intersection positions can also be _{expanded as required} by operating the auxiliary device, of course, but it is intended to determine learned forces. If z.

from which the four must be transferred in the correct color into an end closure, which overall crossing position the four has in the entire section. In the present example in FIG. 3, 65 goes

Cores of the quad in Fig. 4 determined result.
This therefore results in the following for the auxiliary device

So the question as to what overall crossing position does the quad have over the entire cable route or In other words, to which total intersection position the intersection positions 2, 5 add up and 7.

position for a cable section with twenty junction sleeves is to be determined and the existing auxiliary device contains only five switches, you can proceed as follows: You set the crossing positions of the first three sections and the two junction sleeves located in this route on the switches of the measuring device and reads the intermediate result on the instruments StI and ΛII. Let us assume that this would result in the crossing position 6. This crossing position 6, which represents an intermediate result for the entire cable route, is now set on switch 1 of the device and on the second, third, fourth

and fifth switches will then continue to be the intersection positions of the next in sequence Sections and sleeves are set and a new intermediate result is then determined, the is again stored in switch 1 of the device, etc. In this way, any number of consecutive subsections and sleeves, and yet only needs a limited one Number of switches in the auxiliary device.

Another task, which can also be solved in an elegant manner with the aid of the method according to the invention and which is of practical importance, can also be as follows: There are already a number of intersection positions carried out in the subsections and intersection sleeves. Which crossing position must be made in any sleeve to z. B. to get the total crossing position 1? Such tasks can also be solved very easily with the auxiliary device. In this case, only three switches are required, the first and third of which simulate the overall crossing position of the two sections, while the second switch is changed until the instruments StI and St II show the deflection required for overall crossing position 1. The switch setting required for this then corresponds to the crossing position to be carried out in the socket.

However, the use of the auxiliary device is by no means only for determining the resultant of the intersection positions determined, but can also be done in the following area:

As shown in FIG. 7, the instruments StI and StII in the measuring device M can also be switched to the sockets w, r, gr, bl with the aid of the switch 6 ″. contains three junction sleeves I, II, III, the quad to be measured is inserted in the correct color, while at the other end of the cable 1 the quad is fed via a portable auxiliary device H containing the batteries BI and SII with series resistors Rl, R2 and key T. For the In the event that the overall crossing position determined by the auxiliary device corresponds to the practically implemented crossing positions in the cable, the instruments StI and StII must display the same value when the key Γ is pressed. If this is not the case, errors have occurred when performing the crossings. The ohmic resistance of the conductors present in the cable can be taken into account by the series resistors Rl, R2 and is also not critical, since the instruments in their Deflection only need to show the difference between i and the selected value ft'i. In the event that none of the instruments gives a display, as shown in FIG. 8, the pushbuttons present in the measuring device M and auxiliary device H are used. If you press z. B. the built-in in auxiliary device H pushbutton 2 ', the wire in question is connected to earth. If now the push button 2 in the measuring device M is pressed, the instrument I should show a deflection in cooperation with the battery B. If this is not the case, press one of the other pushbuttons 1, 3, 4 until you see a rash. If this is the case, for example when pushbutton 3 is pressed in measuring device M ₁ , it can be said that the red and green wires of the quad have been interchanged in a junction sleeve.
