Description

The invention relates to a device for the central visual display of. Switch positions For test stations where several measuring devices are individually operated via rotary switches or other multi-stage switches. or switched on in connection with each other.

It is known to combine several measuring devices in one measuring station for test purposes to different To enable measurements by separately or jointly switching on these measuring devices. The connection these measuring devices to the test object and the setting of the various measuring ranges takes place mostly via rotary switches or other multi-stage switches, which in turn are group-like Distribution can be selected by means of a preselection switch.

It is a disadvantage of the known arrangements for such measuring stations that with multi-digit, e.g. decadic Distribution of the switch positions a good overview of the measuring devices that have just been switched on and the measuring ranges set is missing and the setting may also cause difficulties if z. B. the graduation around the Switch is arranged and thereby partially for the operator through the switch button or the Hand is covered.

The invention is based on the object of providing a device for the central visual display of To create switch positions, which by summarizing the displays at one point of view a enables fast, reliable observation of all the respective previous settings, but in spite of the use of separate display elements for the different ones Place values, e.g. B. One, tens, etc.%, the multi-digit, z. B. decadic, subdivided labels of the switch positions with only one switching point that is used for the Arizei control for each to be displayed Switch position allowed to get along.

This object is achieved according to the invention in that to display a switch position by a multi-digit code only one switching point is provided and this switching point with the individual Aiizeigcorgawcti and decoupling represent the multi-digit code number of the switch position Rieluleiter is connected.

Circuits are known in measurement technology in which measured values are displayed optically on a central device. But these circuits require a separate connection between the display device and the measuring device for a number display constructed on a decadic basis for each target digit of a multi-digit number. In the case of a malnutrition, however, this would be useful for various measuring instruments. lead to a large circuit complexity, device to the central optical

since each rotary switch, via which the display device is connected to the measuring device, has a corresponding number of switch arms and switch contacts would have to be equipped.

In contrast, a device constructed according to the invention for a central optical display is required Due to the decoupling light guides used, it is completely independent of the multiple digits of the to be displayed WVrtes only a single connection between the display device and the Measuring device. ■

If, for example, it is a two-digit decade display, then each identification of a switch position is made up of two digits, e.g. B. in the first decade from the digit 0 for the Zeliner place and one of the digits from 0 to 9 for the corresponding units, in the second decade from the digit 1 for the tens and again one of the digits from 0 to 9 for the units, etc. The resulting parallel connection of a single switching point to several display elements and a single display element to several switching points is made possible by the decoupling circuit according to the invention without the parallel connections influencing one another.

When using a Lampciitableaus for the display this can be set up in decadic form, so that the required number of lamps is limited to a minimum. For the decadic display of one hundred column positions (00 to 99; ), only twenty lamps are required, ten for displaying the tens (0 to 9) and ten lamps for displaying the units (0 to 9) So this becomes

with low miud ;; a very space-saving and clear central display »-; achieved. This arrangement can also be used without changing or expanding the Richtleiteriddc1 and the display elements for several, individually operable switches, of which by means of appropriate Eiiistelluni, 'a' preselection switch can always be used in; the. For the display, certain switching points d <i individual switches with the same identification can be activated in parallel. By using the guide field, it is achieved in this case that only the display elements characterizing the position of the selected switch gate At a measuring station equipped with such an optical display, the media operator can easily and safely set the individual switches using the optical display to the measurement object and the setting of the various measuring ranges without regard to the legibility of the scale division on the switch itself or the size and spatial arrangement of the individual switches can be carried out and read. be kept free. H ier makes it possible to use a decoupling directional conductor field according to the invention, also to use the Koutaktbähn serving for display control for switching purposes, for example for controlling relays. An exemplary embodiment of the connection is shown schematically in the drawing. A denotes the path of a main switch, which is provided with six contact points 0 to V according to the illustration in the figure. In the circuit of the contact points I to V there is a lamp / 1 to LV. About the train /? This main switch is connected to small rotary switches D1 to D3. This series connection of two switches ensures that the numerous control buttons on the individual measuring devices are omitted and that a uniform principle is used for all measurements. The Kontaktbahiien this Klcindrehschalter, of which z. B. each comprises twenty-five contact points, are connected in parallel and connected via a decoupling Riclitleiterteld G, which is composed for example of rectifiers, with Laiu vu £ 0 to E9 and ZO to Z2. With R is a tableau in which the LiAnipen are arranged centrally. The Stromversorgui - this facility takes place via a TiansformatM- '/'. which shows, for example, at the same time: that the device is under tension and. is ready for use. Then the main switch is operated first, the positions of which characterize individual main measuring groups, such as pulse time measurement, line testing, etc. If the main switch is set to contact TI, for example, the lamp LIl in the panel next to the letter G lights up a 2. This position of the main switch is assigned to the small rotary switch D2 in the figure, via which the final setting is made (e.g. line test - measuring the resistance of the line loop ajb). If, for example, the small rotary switch has now been set to contact 19, the lamps Z1 and £ 9 receive voltage and light up the number 19 behind the letter i7 on the panel, so that the final display is now G2 F19. The lamp panel can of course be designed differently with regard to the size and arrangement of the points to be displayed. Assuming that the main switch has twelve and each small rotary switch has twenty-five contact positions, three hundred different settings can be displayed centrally with little effort. The exemplary embodiment described and shown is not restricted to test stations. The device according to the invention can be used for all setting and switching tasks.
