The invention relates to a device for monitoring a plurality of devices assigned in groups arranged signal points that cover a plurality of display devices mask with openings contains, the number of which corresponds at least to the number of display devices, and which the Characters indicating individual groups are assigned, which are sequentially assigned by a setting device can be conveyed to the relevant opening, an electrical circuit being provided, each of which a connection between several signal points of the same arrangement within the groups and the same Display device can be produced.

Devices of this type are used for data processing systems, e.g. B. for digital computers and Tabulators needed when a large number of signal points within the machine are on a relatively small space z. B. to be monitored for errors to the operating staff Area to show where the cause of an error lies. Smaller machines often do not have enough Space for large billboards, and the initial cost must be as low as possible are held, so that there is a need for a monitoring device which, despite sufficient Compactness but a large number of signal points of the machine can be detected.

A device for remotely displaying the coordinates of a defective fuel element in a nuclear reactor is known. The fuel elements are arranged in 12 groups of 24 bundles each, the latter having four channels for receiving one fuel element each. If one of the more than 1000 elements becomes defective, the detector assigned to this element emits a signal which controls the electromechanical monitoring device so that this defective element is indicated to the operator. The monitoring device contains an endless belt that can be driven by two electric motors, on one side of which the symbols indicating the groups and bundles are attached, and on the other side of which there are four symbols for the channels combined to form the bundle. The belt runs behind a narrow transverse slot along a mask and is driven by one motor until the signs of the bundle in which the defective element is located appear, and then continues to be driven by the other motor until the Character of the group concerned appears. In addition, one of four lamps behind the belt lights up to monitor several

additionally display the channel within the bundle that contains the defective element.

When operating nuclear reactors, it is extremely important to have all of the fuel elements at the same time to be able to monitor their deficiencies. When operating calculating machines, on the other hand, it is sufficient to if the operator also supervises signal points arranged in groups in groups.

The invention is based on the task of selecting the group to be checked or monitored the defective point or the signal point through to the operator without delay to indicate any mechanical adjustment movements.

This task is assigned to a device for monitoring several signal points in Devices with multiple display devices indicated by a mask corresponding to one of the number of display devices corresponding number of openings is provided, are covered, with several each Opening associated markings, an adjustment device, which one after the other the idea each of the individual characters behind the associated opening is made possible and with a group of several AND gates, one input each with a

Signal point is connected and its outputs via an OR gate are combined, achieved according to the invention in that the signal for the further Input of each of the AND gates through a switch controlled by that setting device is controlled, which corresponds to the characteristics that can be imagined behind the corresponding openings, so that each indicator is used to monitor multiple signal points.

According to a further embodiment of the invention, neon lamps can be used as display devices, which indicate the magnitude of the voltage at the signal point Show.

The characters indicating the group of signal points can be printed on a translucent plate be arranged, which is adjustable with the help of a rack relative to the mask opening, and in the Toothed rack can engage a manually rotatable adjusting wheel. On the other hand, they can also do the group of signs indicating signal points mounted on a rotatable drum and through an opening the mask be visible, and the drum can be relative to the adjustment device via a gear Mask opening can be adjusted by hand. The cross section of the drum can be polygonal where the number of sides of the polygon corresponds to the number of groups of signal points. the Mask openings can be arranged side by side in several parallel rows, each of which a drum is assigned.

The invention is described below with reference to the drawings. It shows

F i g. 5 is a plan view of the mechanical part of the display panel of FIG. 4,

The in F i g. The gate circuit shown in FIG. 1 processes binary signals, i. H. Signals from two different Values which are hereinafter referred to as "low signals" and "high signals" and from those the low signal more negative than the high signal and the high signal more positive than the low Signal is regardless of which pole of the voltage source is grounded. F i g. 1 shows on the right four output lines, each of which is connected to one of the Neon Ibis 4 neon lamps. Any of the output lines is connected to one of the inverting amplifiers 10 to 13. Used for the inverting amplifier A low signal is supplied, then the output line and the neon lamp connected to it receive a high signal. Each of the inverting amplifiers 10 to 13 is connected to the output of one of the OR gates 4 to 17 for low signals. Each of these OR gates 4 to 17 buffers nine inputs, from each of which is fed by one of the AND gates 18 to 53 for low signals. The in F i g. 7 shown The display board contains a total of 32 neon lamps, which are controlled by eight gate locks Fig. 1 are provided.

The low OR levels 14.15, 16 and 17 produce a low output when either input is low and produce a high output, when all inputs are high. The low AND levels, such as AND level 27, generate a low output when all inputs (two in this case) are low and produce one high output when the input is high. The inverting amplifiers 10, 11, 12 and 13 generate high output signals when their inputs are low and produce low output signals, when the input signals are high.

ίο The input to each of these AND gates is controlled by a switch which is connected to the character selector in FIG. 2 is connected. In the exemplary embodiment, nine switching positions are provided, and only one of the vertical lines according to FIG. 1 is negative for a selected brand. The lines are labeled A to /. The other input to each AND gate comes from the test site in the system to which the display device is connected, e.g. B. data processing system, calculator, tabulating punch, etc. One of the 36 inputs that belong to this part of the circuit, for example, to the carry flip-flop of the counter of a computer or a processing system and another to the switch, which with the card feed of a punch card reader or punch, etc. is connected. The 36 input terminals are designated 54 to 89, the input terminals 54 to 62 being connected to the AND gates 18 to 26. The outputs of these AND gates control the lighting up of the neon lamp 1 via the OR gate 14 and the inverting amplifier 10. The inputs 63 to 71 are connected to the neon lamp 2, the inputs 72 to 80 are connected to the neon lamp 3 and the inputs 81 to 89 connected to the neon lamp 4.

A detailed description of the operation of this circuit should be superfluous. If, for example, a character position is selected which provides a negative signal on line A , then a first negative input is applied to each of AND gates 26, 35, 44 and 53. Thereafter, if a low signal appears at one or more of the terminals 62, 71, 80 or 89, the relevant AND stages 26, 35, 44 or 53 introduce a low signal at both inputs, which causes the relevant AND stage to generate a low output signal. AND stages that receive high inputs produce high outputs. The output signals of the AND stages 26, 35, 44 and 53 are passed to the corresponding OR stages 14, 15, 16 and 17. Those OR stages which receive low input signals produce low output signals which are reversed by the respective inverting amplifiers 10, 11, 12 and 13 to produce high output signals which illuminate the associated neon lamps 1, 2, 3 or 4, whereby the presence of a test signal is displayed. Those OR stages which receive high input signals produce high output signals which are converted to low signals by the inverting amplifiers. These low signals cannot illuminate the associated neon lamps, indicating the absence of test signals. If the circles are followed in a similar way which are connected to the character positions marked by the lines B to /, then the same results are obtained. Each of the

nine input lines switches one of the nine AND gates, which with each of the four neon lamps are connected. The neon lamp is then controlled by the input line of the selected gate.

In Fig. FIG. 2 shows a circuit for the signals which are transmitted on one of the lines yl to / the F i g. 1 occur. The output lines of FIG. 2 are corresponding to the lines in FIG. 1 marked with A to I. It can be seen from this figure that when the contact arm 90 of the switch 91 is rotated, a negative potential of approximately -30 volts is applied to lines E, H, I, D, C, G, B, F and A in sequence . At the same time, the rotary selector 92 switches eight of the nine lines to ground to which the voltage of -30 V is not applied. As the F i g. 5 and 6, the contact arm 90 and portion 92 are controlled by a wheel or disc which is manually operated to change the characters on the display panel.

FIG. 3 shows a schematic diagram of part of the circuit shown in FIG. 1 in logical form will be shown. This circuit consists of a switching or driver element for controlling a every neon lamp on the scoreboard. In the embodiment there are 32 neon lamps and hence 32 driver elements are available, the driver element being one transistor and two in the circuit Transistors are used, which are marked with ßl and β 2.

The output signal for controlling the neon lamps is taken from the collector of each transistor. The emitter is grounded and the base is the input. Although PNP transistors are shown, NPN transistors can also be used if necessary with a corresponding change in bias and signal levels. Considering transistor β1 and the lines leading to the base as the equivalent of amplifier 10 and OR gate 14 in FIG. 1 and transistor β 2 as the equivalent of amplifier 11 and the OR gate of FIG then the transistor β1 controls the neon lamp 1 and the transistor β 2 controls the lamp 2, as indicated at the outputs of the two transistors. The input terminals on the left in the figure are marked in such a way that they correspond to the terminals of FIG. 1 match. It will be understood that, for example, if a signal at terminal 54 is negative, that signal will have no effect on transistor β 1, which is normally biased or off or non-conductive when the signal on line E is not is also negative. Only in this case do the diodes 93 and 94 have the effect that the base of the transistor ß1 receives a higher negative voltage, so that this transistor passes more current and emits a higher positive signal at the collector.

In Fig. 4 shows an embodiment of the display panel according to the invention. This board, which is attached to the system to be monitored, consists of the mask part 95 with the four longitudinal openings 96, 91, 98 and 99. Since 32 signal or neon lamps are provided in the illustrated embodiment, each opening comprises eight subdivisions or windows, each window is connected to a signal or neon lamp. By means of the control wheels shown in the following figures, a transparent plate or translucent membrane, which is attached to the left behind the panel 95, can be moved up or down and adjusted with its differently marked plate positions to the four openings.

A translucent sheet attached to the distributor plate of FIG. 4 can work together and also with the circuit arrangement of FIG. 2, has nine different positions, so that nine different Displays in the windows, such as window 100; can be arranged. Some or all of them Fields of the plate that are visible through the openings 96 to 99 are marked at a certain point, which indicate the machine point to which the signal lamp of a certain window is switched is. If z. B. at the opening 96, the window 100 is connected to a flip-flop, which is at a If the error in the card reader takes effect, the sign »READ« appears in this window only if there is an error in the card reader part of the system on which the display board is attached is present.

Since each point of the transparent plate can indicate 32 points in the system to be monitored and since there are nine plate locations, a total of 288 locations can be displayed. Always with one This structure can be expanded in a very simple manner by still saving significant space either more than nine transparent plate positions are provided or the number of windows is increased per slot, whereby the displays or neon lamps are increased accordingly. It is also clear that the openings, although they are horizontal on the panel 95 shown, can just as well run vertically; in this case the transparent plate moves from the right to the right Left.

F i g. 5 shows a rear view of the machine part with the display panel of FIG. 4. As shown in the figure As can be seen, the two support plates 101 take the display panel and the associated parts of the monitoring system. As in FIG. 4 the reference number 95. On the support plates 101 are the four rows of signal or neon lamps with the reference numerals 102, 103, 104 and 105 appropriate. Each signal or neon lamp in each of these four rows is behind a window, as in the description of FIG. 4 was found. The transparent plate shown in FIG. 4 mentioned, but was not shown, has the reference numeral 106. It can consist of glass or plastic material and is connected to the rack 107 which is operated by a pinion and the corresponding gears 108 will. The gears 108 in turn are driven by the wheel 109, which is shown in FIG Execution is to be operated manually.

The rear derailleur of FIG. 1 is located on the same shaft as the wheel 109. 2. When the wheel is 109 is rotated, the rack 107 moves the transparent plate 106 behind the mask 95 by means of Rack and pinion 108 up or down. Just like the transparent plate, each of the nine Passes through digits, the switch 91 is associated with one of the corresponding nine digits and thereby closes the circle of FIG. 2 the corresponding switching contacts. At a given Place one of the nine lines of switch 91 is connected to the gate circuit of FIG. 1 laid. At that time-

Punkt, the corresponding signals from the machine points to be monitored light up a certain signal or neon lamp, so that the symbol marked on the transparent plate 106 is visible on this window.

In Fig. 6 is a further embodiment of the mechanical movement, which with the circuit of the F i g. 1 to 3 can be connected, shown. The rows of signal or neon lamps are hidden in this figure, while the terminal strips for the lamps are visible and have the reference numerals 110, 111, 112 and 113 . Instead of the transparent plate 106 of FIG. 5, four drums with the reference numerals 114, 115, 116 and 117 are provided. These drums are nine-cornered in cross-section and each of the nine panels has eight fields, each field corresponding to a window on the display board itself. Some or all of the fields can be marked accordingly to indicate a point in the system to be monitored that is connected to the signal or neon lamp on one of the windows. The gear of FIG. 5 is also shown in FIG. 6 uses and bears the same reference number 109, but instead of the rack and pinion drive of FIG. 5, a gear transmission is provided in which a gear is actuated directly by gear 109 and drives each gear connected to the four drums via intermediate gears. The gears are marked with the reference number 118 . The switch of the F i g. 2 is also used in this embodiment and has the same reference number, ie 91.

The advantages of the construction of this embodiment emerge clearly in FIG. 7 emerges, which is a front view of a display panel associated with the mechanical part of FIG. 6 cooperates. This display board does not require a transparent plate as the row of neon lamps remains uncovered and only the sign under each neon or signal lamp is illuminated and by rotation the drums is changed. This gives you a larger field for both labeling of the window as well as for the visible light.
