Description

EVENT REPORTING LOGICAL CIRCUIT The invention relates to a logic circuit for reporting events, series of events.

In the field of operations management and business management, but also Various events can occur in other areas. These events claim the implementation of various measures after their publication or precautions.

The complexity, or the time and effort required the precautions required by the emergence of events grow to a large extent with the number of possible events and with the number of locations, where their appearance is to be expected. Through the development of economic Life such a display system is claimed, with which the communication of those who have entered Events with the interested parties and thus the implementation of the If the events occur, the measures that have become necessary are carried out quickly and continuously can be. This process should also involve the frugality necessary in doing so Work force to be taken into account. The occurring tasks can e.g. In connection with the used in the operation of a Rotel, the assigned or occupied rooms or apartments can be recognized well.

In the hotel establishments appear in connection with the to be awarded Rooms or apartments: - the room is unoccupied and can be forgiven; - the room is taken, therefore occupied; - the occupied Room is just being tidied up (repeated daily); - the room becomes free, the guest has paid his bill: - a will be made in the vacated room general cleaning and tidying up; - the tidying up is finished; - the controller checked and accepted the condition of the room after it was cleared. That Room can be reassigned.

The individual reported events generally claim to be carried out of certain measurements and the implementation of the latter form the same reporting events.

The notification of the same takes place in the rooms (apartments) or to the individual workplaces the company; such workplaces are the cash register, the entrance gate (reception), the manager's office, the room of the carpenter, the telephone exchange. lia result of the messages can be sent to the, with signal lamps working boards the occupied rooms, the vacant rooms, the whereabouts of the the carpenter who arranged the clean-up work, the payment of the Bill, etz. can be identified clearly and quickly. In the event of one contemporary hotels with several hundred to several thousand rooms the advantages of such a signaling system are evident.

The well-known event display systems that work with complicated logic would have such a complicated circuit and structure have a practical one Would make it almost impossible to use. When using electromagnetic Relays would further the large number of movable mechanical construction elements as well as the complicated yard wiring also give rise to frequent defects.

In addition, there would also be a large, professional one for constant maintenance trained staff required. Operational disruptions would occur all the time. Also the The space required for such a facility would mean such a relay system could not be designed in such a way that the circuit belonging to the same room would form a single assembly unit.

Therefore, the complexity increases with such a design and searching for errors that occur will often be necessary.

The purpose of the invention is to provide a logic circuit and a Create circuit za made of semiconductor elements that do not contain movable components built up and 80 is simple that the logical circuits necessary for each room in the form of cards with printed circuits, each forming a unit are. Therefore, wiring and troubleshooting should be simpler and one event.

Repairs consist entirely of a card swap.

The subject matter of the invention relates to / for reporting events serving circuit. The invention is based #### on the knowledge that the Circuit used AND gates can also be controlled by interrupting the inputs. Pie interruption of one input of the two inputs and one output AND Tore has 11 cases if this input is neither on a character level of 1 or 0 - the effect as if the AND gate was only its only one Own entrance would. In this case the character level is the other input and output the same, 80 that the interrupted input behaves in such a way: as if character level 1 were present at the same.

You would have to instead of the mentioned grip - namely instead of the interruption of the input of the AND gate - at this input in the appropriate case the character level 1 switch, this would have the disadvantage that the switch does not single-pole, but two-pole, i.e. not one for each circuit, but two conductors would have to be led so that the circuit is more complicated making it difficult to use a single print card per room. Ultimately, troubleshooting and fixing it would become much more complicated will.

With the help of the commercially available logic semiconductor switching units the task can only be solved with significantly greater effort. These switching units cannot due to their dimensions and arrangements on a single print card are provided. so that both the dimensions of the device and the difficulties the detection of errors has increased or increased significantly.

The invention therefore relates to one for reporting events or event series serving logical circuit in the one controlled by AND gates Toggle switches existing storage elements, as well as other AND controlling OR gates Gates are provided. The essence of the invention is that with the AND gates of the storage elements in the circuit of one input hand-operated breaker worry are seeing. The circuit also has so many, controlled by toggle switches and further AND gates actuating OR gates, like the itt one reduced number the toggle switch. These AND gates have at most eo many entrances, £ the number the storage elements. At the outputs of the OR gates are amplifiers and at the Outputs of the amplifier visual signals provided.

To emit flashing signals, the input of the, for actuation one or more AND gates serving the OR gate a generator with one, an output having a variable character level is connected. The repetitive Logical elements of the circuit are in a common assembly unit, e.g. provided on a card with a printed circuit. Close the connection points join a common row of plugs mounted on the card.

In the case of a hotel signaling system, the circuit has in the apartments key-operated underbreakers and in the individual workplaces of the company visual signal panels.

An example embodiment of the invention is in a device to display the occupied or free hotel rooms. Fig. 1. is that Scheme of the logic circuit. Fig. 2. shows the card with the printed circuit, almost in real size.

The main part of the equipment are: K1 and K2, key operated Interrupter in the hotel room, N1 a mandatory push button for control the device, N2 a closing push button in the cash register, N3 an interrupting one Push button at the entrance (at the reception) B a generator with variable exit characters level. L1 .... L4 are at the hotel entrance, at the manager's office, in the telephone exchange, or in the cash register, given away with signal lamps, with green signal lamps in parallel connection; are those to whom, in the reception, with the managing director, in the telephone exchange, by the housekeeper, there were red panels Signal lamps in parallel, in simultaneous actuation and finally for each hotel room (Appzrtemont) there is a waiting room with a printed circuit, which contains the logic circuit. A direct current of 12 V is used as the power source Tension.

The main parts of the logic circuit are: The toggle switches F1, F2, F3 as well as the memory elements consisting of the AND gates E4, E5, 2, E7. Switched to the outputs P, Q of the aforementioned storage elements or toggle switches AND gates E1, E3; the one connected to the interrupter Kl AND Gates,; the OR gates connected to the outputs of the latter three AND gates V1 and V2; the amplifiers Al and connected to the outputs of the OR gates The logic circuit is connected to the external circuits via the series connector terminals D. connected. A voltage of - 12 V reads at terminal U1, and the at terminal Earth.

The states of the circuit are as follows for the messages: I. When the breaker pushbutton N3 is pressed, all of the light bulbs L1 go out .... L8. In this way, the entrance of the hotel indicates that the room is pre-rented became.

II. By actuating the interrupter K2 with the insertion of the Key, the red light bulbs L 5 ..... L8 will give a flashing signal, while the green light bulbs L1 ..... L4 remain dark. The housekeeper clears in the room and can be reached there - also via the telephone. After peeling of the key, the original state I. is restored, all lamps are dark.

The switch key is with the housekeeper.

Conditions 1. and II. Are repeated when the room is handed over Day after day.

III. If the closing push button N2 pressed, the light bulbs L1 ..... L8 light up continuously. The cashier gives In this way, the customer is informed that the guest has paid his bill and off moved out of the room.

IV: The interrupter K1 is after the state III.

actuated by inserting the key, removing all the light bulbs L1 .... L8 light up continuously. So this state is different from the state II. Before which the state I.

was present. This shows. the maid said that she was free become Raua a big cleanup.

V. After removing the key, the interrupter K1 closes, after which the green light bulbs light up continuously, while the red The light bulbs go out and the big cleaning up is over.

VI. The interrupter K2 is now actuated by means of the key and then removed the key. The green light bulbs stop flashing and the lighting of the same L1 ..... L4 becomes continuous. This key is at the room controller, who in this way reports that the clean-up work is a satisfactory one and the room can now be rented again. As a result of the repeated riveting of the room, the state T has recently occurred.

Vii. By pressing the sporrent push button N1, the Incandescent lamps L1 ..... L8 all light up continuously and evenly. This control process does not change anything in the state of the displays. With the release of the push button it sets the previous state is set again, so that this control on the Sigrealen no change caused.

The activity of the logic circuit, as well as the occurrence of the different message. states can be based on Fig.1. be inferred.

In the basic state, the push buttons N1 and N2 are in their break position, the push button N3 and the switches K1 and K2 in their closed position. The logic character level is present at the outputs P1, P2, P3 of all toggle switches F. 1.

There is at least one of the inputs of the AND gates E @, E2, E6 that voltage level 0 of terminal U2, so that these AND gates block. Sound the exits 21 and P2, there is E7 at both inputs of the AND gate and therefore also at the output of the same a logic character level 1. The AND gate E1 receives from the output Q1, the AND gate E2 via the interrupter K1 and the gate E3 of output Q2 a 0 Signal so that the output of all three AND gates receives a logic 0 signal are the outputs of the OR gates V1 and V2 and the outputs of the amplifiers A1 and A2 at level 0. All light bulbs L1 ..... L8 are dark. This is the state I.

If the interrupter K1 is actuated from state I., 80 this results in state II. In this case, one input becomes deß AND gate E2 will be interrupted and the gate will act as if it were just a single one Would have input, but which would have a variable starting level Generator B is connected.

So this output character level changes between 0 and 1, see above that alternates between the output character of the ODSR gate V2 and the output character of the Amplifier A2 comes into its own. The red light bulbs L5 ..... L8 flash accordingly.

Removing the key, thus closing the key breaker restores the previous state I.

As a result of the closing of the push button N2, the original AusSan67 P1 located on level 1 to stand on level O come, whereby the tilting circle tilts and the output Q1 comes to character level 1. This is possible because the one input of the UltD Gate E5 is via the push button N3 and therefore also the output - namely R1 - are at character level 0. This The event does not affect the toggle circuit F3, although it is the output of the AND gate changes to 0, the output of the AND gate E6 is also 0 as a result of the am Output Q1 appearing character level 1 are all inputs of the AND gate El and so the output is also on character level 1. This creates -the output characters both OR gates V1 and V2 as well as the output character of both amplifiers A1 and A2 are on character level 1, so that all signal lamps L1 ..... L8 light up. This is the state III. The actuation of the interrupter K1 results, if this according to state III. occurs, state IV. which differs from state II. As a result, the one input of the AND gate E4 is interrupted, whereby the AND gate E4 80 is designed as if it had only one entrance, at which, in the present case, character level 1 is available from output Q1 is, also at the output of the AND torc E4; d. H. the tilt circle F2 tilts. The drawing level of output P2 changes to 0 and the character level of Q2 to 1; the AND gate and block the OR gates V1 and V2, the output character of the amplifiers A1, A2 is O. The AND gate E2, however, leaves the one given by Gonerator B to its one input Signs of varying levels through, as its other entrance at the breaker K1 is interrupted and therefore acts as if there was no such thing. In the same way, however, Bs leaves the alternating one switched to one input Sign also through the AND gate 5, as it is level 1 of the Auaganges Q2 owns. In this way, both OR gates V1, V2 and thereby both Amplifier A1, Al characters of varying levels so that all light bulbs L1 ..... L8 flash.

If the interrupter K1 is again due to the removal of the key blocks, the AND gate E2 receives a 0 character via its one input and blocks, whereby the OR gate and the amplifier A2 also block. The red light bulbs L5 ..... L8 are therefore dark, whereas the green light bulbs L1 ..... L4 remain unchanged flash. This is state V.

When the interrupter Ka is actuated, it interrupts one input of the AND gate E6, whereby the character level 1 of the output Q2 comes into play at the other input and lets the character through. The tilting circle B3 therefore overturns and character level 1 appears at output Q3; this forms the character sent by the OR gate V1 and the amplifier instead of ### the previous variable character level whereby the previous Minking of the green incandescent lamps L1 ..... L4 is followed by a continuous glow of the same. The state II. Remains upright even after the interruption K2 has been withdrawn, since the character 0 is present at both inputs of the tilting circle F3, whereby the position of the tilting circle remains unchanged.

The interruption of the push button N3 sets the state I. again. This means that only the character 1 of the output is displayed at AND gate E5 Q3 come into play, the tilting circles and F2 tilt over, at the outputs Pl, P2 character level 1 appears. The output located at character level 1 of the AND gate E7 connected to the two outputs tilts the trigger circuit F3 into such a location. that the character level of the output P3 becomes 1. This matches with the initial state.

It is very important that the buttons N2 and N3 and the interrupters K1 and B: 2 follow only in the order described, in which the stated conditions can also result while actuating them in a other order is ineffective. The AND gates E4, B5 E6 lock namely the Rib circles J1 F2, P3 such that the actuation of the same nut in the corresponding Step of the logical chain is possible.

The control of the light bulbs L1 ..... L8 as well as the amplifier A1, A2 is done by closing the push button N1 with the help of the OR gates V1, V2 given character.

This is state VII.

The actuation of the push button N1 changes the state of the tilting circles F1, F2,13 not.

The claimed by the establishment. Performance amounts to without the incandescent lamps, in the case of a hotel with 500 rooms to 350 watts
